Digital Display Alignment Tool (DDAT) 5.X About DDAT Version 5.x



2. About DDAT Version 5.x

The Digital Display Alignment Tool (DDAT) software application residing in the control station computer of the Image Generator (IG), allows qualified personnel to perform a wide range of calibrations to ensure the projection system operates at optimum performance. Calibrations executed from the DDAT software application are performed either on a periodic basis, in order to maintain the projection system operating properly or, on a corrective basis when a physical hardware component is replaced. DDAT calibrations, settings and functionalities as displayed on the DDAT Home page are grouped into three options: System Status, Configuration and Calibration. Each of those options expands into more options as illustrated in the DDAT menu hierarchy (see Figure 2-1 and Figure 2-2). To perform calibrations or alignments, DDAT must communicate with the Image Generator, auto-alignment camera, spectrometer and the projector control software to ultimately control each projector (see Figure 2-3). That is why upon launching DDAT, an initialization process verifies that all the various hardware/software elements are functioning properly. Alignment correction commands issued by DDAT are sent either to Image Generator channels or projectors depending on the type of alignment being performed. For example, geometry correction commands issued by DDAT are sent to the IG channels as the image geometry is corrected in the IG, not in the projector. However, other types of correction issued by DDAT such as focus, zoom, and lens shift are sent to the projectors by way of the Projector Control software residing in the control station computer. For detailed descriptions of the main features and functions of this DDAT version, refer to the following paragraphs. NOTE: The DDAT software as described in this user reference guide should

only be used by qualified personnel understanding the DDAT effects on the projection system.




Figure 2-1 DDAT – Home Page NOTE: DDAT software by default opens as a full screen menu page. To

reduce/maximize menu page size on monitor, toggle keyboard function key F9. To minimize DDAT window press function key F8. Equally acceptable if so configured clicking on DDAT button in taskbar will toggle menu page between minimized to taskbar and visible on desktop. For an overview of menu tree and menu/submenu groupings refer to “Reference – Illustrated Presentation of DDAT Menu Pages & Hierarchy”.

Figure 2-3 DDAT and Projection System (Typical)




2.1 System Status The System status page provides an overall status of various hardware/software elements required by DDAT which are available from the Hardware status and Visual status buttons (see Figure 2-4). Clicking on the Hardware status button displays the Hardware System Status page as shown in Figure 2-5. Clicking on the Visual system button displays the Visual System Status page as shown in Figure 2-6.

2.1.1 Hardware System Status

This page provides an overall system status and individual status of systems listed below:

• IG system (channels) • Projector system • Auto calibration system • VCM Management system

The individual status of systems is shown by a red, yellow and green light indicator. A red light indicator signifies a major problem and must be fixed otherwise certain DDAT functions will not work. A yellow light indicator signifies a minor problem that should be addressed but DDAT may still work. A green light indicator signifies system operates properly. The overall system health indicator summarizes by consolidating each system individual status that is then represented in the form of a percentage and a yellow and green light indicator. NOTE: Since DDAT goes through an initialization process shortly after

launching DDAT, it is good practice to verify the overall status of systems as shown in Figure 2-5.

2.1.2 Visual System Status

This page provides an overall status of all projector lamps used in the projection system. At a quick glance the user can see the remaining lamp hours for each projector and determine whether or not it is time to change the lamps.

2.2 Configuration The Configuration Main page as shown in Figure 2-7 provides the capability of configuring, interfacing and troubleshooting several types of DDAT hardware and software parameters, either during an initial installation or as corrective action. The configurable DDAT hardware and software parameters are listed below and described in the following paragraphs:

• Network • Camera • Spectrometer • Lamp Management Configuration • Color Reference • Day Luminance Reference • Hardware Inspection - Calibration • Designer Mode

Entering the Configuration menu should only be done by qualified personnel as inadvertently entering a wrong parameter could cause the projection system not to operate as intended.

2.2.1 Accessing Configuration Page

To enter the Configuration Main page, proceed as follows: (1) From the DDAT Home page (see Figure 2-1), click on Configuration.

NOTE: A password entry window appears (see Figure 2-8). (2) Enter the following password in lower case: maxvue

NOTE: maxvue is a typical password that can be modified. If the password is not entered correctly; a wrong password window appears (see Figure 2-9) but if the password is entered correctly, then the configuration Main page appears Figure 2-7.

2.2.2 Network

The Network page as shown in Figure 2-10 allows the user to select a Station (IG channels or the auto-alignment camera) in order to view and enter the relevant information (IP address and/or PC name if PC name is selectable) to ensure that they match with the ones entered in the IG Main UI. Otherwise if the parameters entered in DDAT are not the same as the ones entered in the IG Main UI, communication between DDAT and the IG channel will not occur. The Get from RTS config button if operational is intended to retrieve the PC host name and the IP address from the IG main UI and load them in DDAT for a selected Station. The test button checks the network connection between DDAT and the selected station (IG channel or the auto-alignment camera). It also establishes an administrator connection. If the connection is good, then a message as shown in Figure 2-11 appears. Figure 2-12 shows information displayed when Detail button is pressed.

2.2.3 Camera

The Camera page as shown in Figure 2-13 allows the user to manually move and configure the auto-alignment camera. Moving the camera manually can be done to observe a different area of the BP screen or simply to troubleshoot the camera and see if it is working properly. If camera settings are changed and the camera does not move it is indicative of a camera related problem (camera, cable connection, power adapter, etc). This page includes: a live view window, a Configuration Settings window and various position, focus, zoom and iris dropdown boxes to alter camera parameters.

Figure 2-13 Camera Page




This Camera page also includes several control buttons listed below:

• IR filter and Auto • Backlight • Restart Camera

The IR filter button removes the colors from the camera video image. This button improves the camera view in low visibility images. The toggle Auto/Manual button controls the IR filter. In Auto mode the camera will adjust itself to the image it is viewing while the Manual button forces the IR filter. The Backlight button when pressed adjusts the video image being displayed in the live view window by rescaling the video image. This is useful when the image displayed on the live view window is too bright. The backlight button then attenuates the video image to a useful viewable video image. The Restart Camera button simulates a power ON/OFF that simply resets the camera to the reference position as well as resetting its indexes. The live view window is discussed in paragraph 2.4.




2.2.4 Spectrometer

The Spectrometer page (see Figure 2-14) allows qualified personnel to analyze the data received from the spectrometer.

Figure 2-14 Spectrometer Page




2.2.5 Lamp Management Configuration

The Lamp Management Configuration page as shown in Figure 2-15 gives the user access to lamp profiles and analysis tools for each/all of the projector channels. For an example of how this page is used refer to paragraph 5.2.1.

Figure 2-15 Lamp Management Configuration




2.2.6 Color Balance Reference

The Color Balance Reference page as shown in Figure 2-16, allows the user to adjust the individual Red, Green and Blue (RGB) color intensity of each projector, in order to obtain a balance between the desired white and the white generated by each projector without losing luminance. A technician performing the color balance reference calibration uses the DDAT Color Balance Reference page in conjunction with a chromaticity meter to adjust each projector RGB color intensity, in order to obtain the same white chrominance X and Y coordinates on all projectors. Typically for Sony VW60 projectors the X and Y coordinates of each projector should be X = .299 and Y = .334 when a white color is displayed (see chromaticity diagram, Figure 2-17). Typical values for Sony GH10 projectors are X=.307 and Y = .335. Once the X and Y chrominance coordinates are obtained on all projectors, then the user must start the automated process of acquiring the color settings that was just performed during the color balance reference adjustments, by selecting the Start reference acquisition button. Once saved, the stored values then become the color balance reference. The concept of this calibration is illustrated in Figure 2-18. This page includes the following buttons and utilities:

• Projector selection • Color selection • Up/Down intensity adjustment • Color intensity level indicators • Live view window

The projector selection buttons allow the user to select a single projector to be adjusted or all projectors if the All channels button is pressed. The color selection buttons allow the user to select the either one of the RGB colors to be adjusted for a given projector. If the All channels button is pressed and the white square is selected, the adjustment will affect all three colors for all channels equally. Selecting the Up/Down intensity adjustments buttons increases or decreases the intensity of the selected color. The color intensity level indicators show the percentage of the color intensity.




The live view window displays the area of the BP screen as seen by the camera lens. This window includes basic camera functions (see Figure 2-48). The functionality of these buttons is explained in paragraph 2.4. Selecting the Start reference acquisition button starts the process of acquiring the color settings that was just performed during the color balance reference adjustments. Selecting Clean all color references button cleans away all color references (They are set back to default values). Selecting the Restore default color settings restores the default color settings set during the initial projection system installation. Selecting Restore calibrated color settings restores color settings just performed. Selecting the Save button stores the latest color settings.

Figure 2-16 Color Balance Reference Page




Figure 2-17 Chromaticity Diagram




Using the DDAT Color Balance Reference page, displays a white field.

Using DDAT, select the desired projector to adjust.

Using the chromaticity meter aimed at the channel screen center, measure the white color intensity. Read the X and Y coordinates on the meter: For Sony VW60 projectors coordinate reading should be X=0.299 and Y=0.334. or For Sony GH10 projectors coordinate reading should be X=0.307 and Y=0.335.

If the X and Y coordinates are not as specified above, use DDAT to adjust each color individually until the white chrominance X and Y coordinates are obtained. Note: The red value should not exceed 247.

Figure 2-18 Color Balance Reference Concept




2.2.7 Day Luminance Reference

The Day Luminance Reference page as shown in Figure 2-19, allows the user to adjust the luminance (in Foot-Lamberts) in the blend zone edges of adjacent projectors, in order to obtain the same luminance reading on each side of the blend zone between channels (see Figure 2-20). A technician performing the luminance calibration uses the Day Luminance Reference page in conjunction with a luminance meter to adjust the iris and lamp of each projector, in order to obtain a luminance variation of less than 2% on each side of the blendzone between channels. This is obtained by measuring the luminance in the squares next to the blend zones of each projector (see Figure 2-20). Typically this is done by the technician:

• Finding the weakest blendzone • Putting Iris to 80 % on dimmest projector • Match adjacent to the weakest • Adjust all other adjacent

Once the luminance between channels is adjusted to the desired result, then the user must start the process of acquiring the luminance settings that was just performed during the calibration, by selecting the Start reference acquisition button. Once saved, the stored values then become the Day Luminance Reference. To Set Day Luminance Reference refer to paragraph 5.3.1. This page includes the following buttons and utilities:

• Projector selection • Iris Up/Down • Lamp Up/Down • Live view window

The projector selection buttons on left side of the page, allow the user to select a single projector to be adjusted or all projectors if the All channels button is pressed. Selecting the Iris Up/Down buttons increases or decreases the iris opening of the projector, therefore controlling the amount of light to the display screen. Selecting the Lamp Up/Down buttons sets it to HIGH or LOW. Usually for the day luminance the lamp is set to HIGH. The live view window displays the area of the BP screen as seen by the camera lens. This window includes basic camera functions just like the one used in the Color Balance Reference page (see Figure 2-48). The functionality of these buttons is explained in paragraph 2.4.




Selecting the Start reference acquisition button starts the automated process of acquiring the Luminance settings just performed during Day Luminance Reference adjustments. Selecting the Restore default luminance settings restores the default Luminance settings set during the initial projection system installation (typically iris set at 75% and the lamp set to High). Selecting Restore calibrated luminance settings restores lumin. settings performed. Selecting the Save button stores the latest Luminance settings.

2.3 Calibration The Calibration Main page allows the user to perform calibrations on individual projectors or on all projectors at the same time. Calibrations are either fully automated or performed manually (see Figure 2-22). Calibrations and alignments available from the Calibration Main page are listed below:

• Projector alignment • Geometry • Blend plate alignment • Auto calibration • Manual Calibration • Miscellaneous Tools

2.3.1 Accessing Calibration Main Page

Accessing the Calibration Main page is done simply by clicking on the Calibration button of the DDAT Home page (see Figure 2-1).

Figure 2-22 Calibration–Main Page


Calibration 12 Apr 2010 Page 28


2.3.2 Projector Alignment

The Projector Alignment page allows the user to adjust the projector Focus, Zoom and Lens Shift parameters in order to align the projector image to a display reference. The display reference used can be a grid of dots and crosses generated by an alignment projector or reference markers (sticky dots) located outside the Field Of View (FOV) of the Back Projection (BP) screen. NOTE: The alignment reference method used can vary depending on the

visual system type. The Focus, Zoom and Lens Shift adjustments are interdependent as one affects the other, therefore adjusting the projector Focus, Zoom and Lens Shift must be done iteratively and subsequently until the proper result is achieved. Clicking on the Projector Alignment page Focus button activates the Focus In and Focus Out buttons (see Figure 2-23). Clicking on the Projector Alignment page Alignment button activates both, the Zoom and Lens Shift buttons (see Figure 2-24). NOTE: On a Sony VPL-VW60 projector only the vertical lens shift is

motorized. Therefore only the Shift Up and Shift Down buttons are functional.

On a Sony VPL-GH10 projector both the horizontal and vertical lens shift are motorized. Therefore all Shift buttons are functional.

CAUTION: BEFORE DOING FOCUS, ZOOM OR LENS SHIFT

ADJUSTMENTS, ALWAYS ENSURE THAT THE PROJECTOR INTERNAL LENS IS UNLOCKED. USUALLY THESE PROJECTORS HAVE A LENS CLAMP LOCKING THE LENS TO THE PROJECTOR. FAILURE TO DO SO WILL CAUSE DAMAGE TO THE PROJECTOR ELECTRIC MOTORS.

The Projector Alignment page includes the following buttons and utilities:

• Projector selection • Focus & Alignment selection • Zoom In & Zoom Out • Shift Up, Down, Left and Right • Live view window




Figure 2-23 Projector Alignment - Focus

Figure 2-24 Projector Alignment – Zoom & Lens Shift




The projector selection buttons located on left side of the page, allow the user to select a single projector to be adjusted or all projectors if the All channels button is pressed. Selecting the Focus buttons reveals the Focus In and Focus Out buttons. Selecting the Focus In and Focus Out buttons changes the lens focal distance. Selecting the Alignment selection button reveals the Zoom In & Out buttons and the lens Shift Up, Down, Left and Right buttons. Selecting the Zoom In & Out changes the internal lens magnification. Selecting the lens Shift Up, Down, Left and Right moves the projector internal lens in the selected direction. The live view window displays the area of the BP screen as seen by the camera lens. This window includes basic camera functions just like the one used in the Color Balance Reference page (see Figure 2-48). The functionality of these buttons is explained in paragraph 2.4.

2.3.2.1 Focus

To focus the projector, proceed as follows: (1) From the Projection Alignment page (see Figure 2-23), select the desired

projector from the list of projectors located on left side of the page.

(2) Click the Focus button.

NOTE: A focus ‘H–shaped’ test pattern as shown in Figure 2-26 or Figure 2-27 appears on screen (pattern may vary). This pattern can also be viewed from the live view window.

(3) Select one of the three increments representing coarse, fine and ultra fine

movements (see Figure 2-25). (4) Use the Focus In and Focus Out buttons to focus the test pattern to achieve an

overall best image focus.

Figure 2-27 H Test Pattern (Variant 2)




2.3.2.2 Zoom and Lens Shift

The zoom and lens shift alignment involves aligning a test pattern to a display reference. Display references are usually one of two types: reference markers (sticky dots) or a grid of dots and crosses generated by alignment projector(s). Depending on the projection system configuration, the alignment test pattern used and the alignment reference method may vary. In most cases, an alignment test pattern as shown in Figure 2-28 is used. The alignment then consists in using the zoom and lens shift buttons, to size and position the test pattern in such a way that the test pattern green surfaces overlay the reference markers. NOTE: Aligning the test pattern green surface to exactly overlay the reference

markers as shown in Figure 2-28 might be difficult. Distribute the error evenly across each of the four corners. The final alignment will be completed using the DDAT Geometry functions.

To adjust the projector Zoom and Lens Shift, proceed as follows: (1) From the Projection Alignment page (see Figure 2-24), select the desired

projector from the list of projectors located on left side of the page. (2) Click the Alignment button.

NOTE: An alignment test pattern appears on screen. This pattern can also be viewed from the live view widow.

(3) Use a combination of the zoom and lens shift buttons to overlay the test

pattern green surfaces on the reference markers. (4) Once satisfactory results are achieved, tighten the lens clamp to lock the

projector internal lens.

NOTE: Aligning the pattern to reference dot might be difficult to perfectly center. Distribute error evenly on all four corners. Reference dot(s) should be inside the (green) cone pattern.

If an alignment slide projector is used and switched ON, then a reference grid of dots and crosses as typically shown in Figure 2-29 could be used. The zoom and lens shift alignment then consists in aligning the outside corners of the test pattern indicated with an X on the reference grid (see Figure 2-30).

2.3.3 Geometry

The Geometry Correction page allows the user to correct the displayed image and align it to a display reference. Aligning the image consists in distorting different surface areas of the displayed test pattern by applying geometry corrections. Geometry corrections issued by the user via the DDAT software, adjust the image at the IG level and not at the projector level. The Geometry Correction page includes the following buttons and utilities (see Figure 2-31): • Projector selection • Image surface selection • Cursor • Cursor increment • Live view Window • Test Pattern Selected Button The projector selection buttons located on left side of the page, allow the user to select a projector from the projection system configuration. The image surface selection buttons allow the user to select a portion of the selected channel image. To select a surface area, click on the required button (refer to Table 2-1). The button changes color and a cursor appears on screen. Cusor markers include the Ref Slide and Camera Auto Centering. Clicking the Ref: Slide Projector button inserts a white marker on the display test pattern. The white marker indicates the adjacent channel reference with respect to the Geometry Surface Area Selection (refer to Table 2-1). The objective is to overlap the green cursor onto the white marker using the cursor movement direction buttons. Clicking the Camera Auto Centering button toggles camera auto centering mode between three states. The cursor increment buttons allow the user to determine the increment by which the cursor will move. Selecting Coarse moves the cursor in large increments, Fine moves cursor in small increments and Ultra-Fine moves the cursor in very small increments. The live view window displays the area of the BP screen as seen by the camera lens. This window includes basic camera functions just like the one used in the Color Balance Reference page (see Figure 2-48). The functionality of these buttons is explained in paragraph 2.4. The pattern button indicates pattern name (SAPF colored shown) and when clicked allows the user to select other test patterns to better evaluate the image in order to perform geometry alignments.

(4) Use the cursor buttons to align the cursor to the BP screen reference marker (see Figure 2-32).

• This is initially done as a first approximation.

• Redo starting with the four corners in order to get properly overlapping

red and green test pattern lines within the blendzone areas.

NOTE: The reference channel (center channel in a three channel system, and in a four projection system is the pilot left channel for a fixed wing aircraft or the pilot right channel for a helicopter platform) must only have its four corners adjusted. Also the top and bottom center dots should only be adjusted vertically. This is to allow maximum image linearity in the system’s reference channel. Blendzone mis-linearity issues are addressed by adjusting top and bottom center dots of non reference channels horizontally.

Figure 2-32 Geometry Alignment Example




• Use the “SAPF colored” test pattern. This test pattern provides both vertical and horizontal lines. The Selected channel shows GREEN colored lines and all non-selected channels have RED colored lines. The goal here is to ensure that all lines found within the blend zones are properly overlapped and being seen as YELLOW. Figure 2-33 shows need for an alignment as seen in the blend zone. See how green and red lines are not overlapping properly. Figure 2-34 shows good alignment as seen from the blendzone. See how green and red lines are overlapping properly and optically add to yellow lines.

2.3.4 Blend Plate Alignment

The blend plate alignment uses the DDAT Optical Mask page to fully extend or retract the projector (external) blend plates, while a technician physically adjusts the blades mounted on the projector. The purpose of the blend plate alignment is to dim the projector light intensity in the blend zone areas of a multiple-projector displayed image. The Optical Mask page as shown in Figure 2-35 appears by clicking on the Blendplate Alignment button found on the Calibration–Main page (see Figure 2-22). NOTE: The blend plates can also be referred to as blades or optical masks.

When the blend plates are retracted or extended, a loud clicking noise is heard from the projectors located on the visual deck.

The Optical Mask page as shown in Figure 2-35 includes the following buttons and utilities:

• Projector selection • Test Patterns • Remove Plates • Insert Plates • Live view window

The projector selection buttons located on left side of the page, allow the user to select a single projector or all projectors to be viewed in the live view window. The Test Patterns selection buttons offers several test patterns to evaluate the image and align the blades alignment. Selecting a test pattern will display the pattern on the display for selected projector(s). The Remove Plates button opens or retracts the blend plates on the projector(s). The Insert Plates button closes the blend plates in order to dim the projector light intensity in the blend zone areas. The live view window displays the area of the BP screen as seen by the camera lens. This window includes basic camera functions. The functionality of these buttons is explained in paragraph 2.2.3.

2.3.5 Auto Calibration

The Auto Calibration page (Home page, Calibration, Autocalibration) as shown in Figure 2-36 appears by clicking on the Auto Calibration button found on the (Main) Calibration page (see Figure 2-22). This page allows the user to perform the auto calibrations listed below:

• Initial calibration • Full calibration • Luminance touchup

At the end of an auto calibration operation, DDAT will prompt the user to save the new autocalibration settings, evaluate the image and if results are satisfactory save the results.

Figure 2-36 Auto Calibration Page




2.3.5.1 Initial calibration

An initial calibration automatically adjusts the individual Red, Green and Blue colors (chromaticity) and the iris (luminance) of each projector in order to obtain a uniform chrominance and luminance across all channels. This calibration will initialize with a new default gamma table. This procedure assumes that day luminance and color balance were performed. All manual corrections to the gamma table will be reset. The golden alignment includes an initial calibration as per paragraph 5.3.3. To run an initial calibration click on Initial calibration (Home page, Calibration, Autocalibration, Initial Calibration).

2.3.5.2 Full Calibration

A full calibration is similar to the initial calibration except the calibration initializes with the existing gamma table. If intensity and color balance are unsatisfactory, rerun initial calibration. If full calibration fails, rerun initial calibration. Full calibration is usually run as part of regular maintenance as per paragraph 5.4.1. To run a full calibration click on Full calibration (Home page, Calibration, Autocalibration, Full Calibration).

2.3.5.3 Luminance Touchup

A luminance touchup automatically adjusts the iris of each projector, in order to obtain a uniform luminance across all channels. This touchup calibration performs luminance image calculations from existing Day Luminance Reference values already established and saved in the system (see paragraph 2.2.7). Based on the calculation results, iris adjustment control commands are sent to each projector. This function is valid where colors still match at all times of day. A possible color shift can occur if iris values change significantly. If color balance is unsatisfactory, run a full calibration. A Luminance touchup is run as required as a part of regular maintenance as per paragraph 5.4.1.




2.3.6 Manual Calibration

The Manual Calibration page allows the user to perform calibrations on individual projectors or on all projectors at the same time. Calibrations available from this page are shown in Figure 2-37 and listed below:

• Gamma • Bias-Gain adjustment • Day Luminance • Night Luminance • Projector settings

NOTE: DDAT software by default opens as a full screen menu page. To





2.3.6.1 Gamma

The Gamma Correction page as shown in Figure 2-38 appears by clicking on the Gamma button found on the Manual Calibration page (see Figure 2-37). This Gamma Correction page allows the user to apply a gamma correction on each projector RGB color individually for a selected intensity point of the graph, in order to obtain an overall uniform match between channels and in the blend zone areas. The Gamma Correction page as shown in Figure 2-38 and Figure 2-39 and includes the following buttons and utilities:

• Projector selection • Color selection • Correction increment • Correction arrows • Live view window • Selectable pattern • Load linear table • Restore default table • Restore calibrated table • Save

The projector selection buttons located on left side of the page, allow the user to select a single projector to be adjusted or all projectors if the All channels button is pressed. The color selection buttons on the top right side of the page allow the user to select the color to be corrected for gamma. The color selection buttons at the bottom right of the page allow the user to select which color(s) to display onto the mirror for cockpit observation. The Correction increment buttons are for a coarse, fine or ultra-fine gamma correction. The Correction Up/Down arrows increases or decreases the gamma correction for the selected color in accordance with the selected correction increment button. The live view window displays the area of the BP screen as seen by the camera lens. This window includes basic camera functions. The toggle pattern button indicates name of selected pattern and if clicked selects following pattern from list available. It allows the user to select a different pattern to better evaluate the image and ease the gamma correction.

2.3.6.3 Day Luminance

The Day Luminance page allows the user to fine tune the day luminance by adjusting the iris opening and the lamp intensity of a selected projector from previously established Day Luminance Reference settings (refer back to paragraph 2.2.7). The purpose of this adjustment is to obtain the same white (Day scene) across the entire image when all projectors are ON. In the day luminance, a white test pattern usually appears on all channels. Refer to paragraph 5.5.2 for a typical Day luminance match calibration. The Day Luminance page as shown in Figure 2-41 includes the following buttons and utilities:

• Projector selection • Iris Up/Down arrows • Lamp Up/Down arrows • Live view window • Selectable test pattern • Restore default luminance settings • Restore calibrated luminance settings

The projector selection buttons located on left side of the page, allow the user to select a single projector to be adjusted or all projectors if the All channels button is pressed. The Iris Up and Down arrows controls the opening of the projector iris. Selecting the Up arrow increases the iris opening, allowing more projector light (i.e. increasing the light intensity); selecting the Down arrow decreases the iris opening, allowing less projector light (i.e. lowering the light intensity). The lamp Up and Down arrows sets the lamp to either High of low. Usually for the Day Luminance, it is set to High. The live view window displays the area of the BP screen as seen by the camera lens. This window includes basic camera. The test pattern button toggles to several test patterns in order to better evaluate the image and perform the alignment. The Restore default luminance settings button allows the user to restore the default iris opening value and lamp setting. Press this button if an incorrect iris setting is mistakenly entered. The Restore calibrated luminance settings button allows the user to restore the recently calibrated luminance iris opening value and lamp setting.




Figure 2-41 Day Luminance Page




2.3.6.4 Night Luminance

The Night Luminance page allows the user to adjust the iris opening and the lamp intensity of a selected projector. The purpose of this adjustment is to obtain the same black (Night scene) across the entire image when all projectors are ON. In the night luminance, a black test pattern usually appears on all channels. Refer to paragraph 5.3.4 or 5.5.3 for a typical Night luminance match calibration. The Night Luminance page as shown in Figure 2-42 includes the following buttons and utilities:

• Projector selection • Iris Up/Down arrows • Lamp Up/Down arrows • Live view window • Selectable test pattern • Restore default luminance settings • Restore calibrated luminance settings

The projector selection buttons located on left side of the page, allow the user to select a single projector to be adjusted or all projectors if the All channels button is pressed. The Iris Up and Down arrows controls the opening of the projector iris. Selecting the Up arrow increases the iris opening, allowing more projector light (i.e. increasing the light intensity); selecting the Down arrow decreases the iris opening, allowing less projector light (i.e. lowering the light intensity). The lamp Up and Down arrows sets the lamp to either High of Low. Usually for the Night Luminance, it is set to Low. The live view window displays the area of the BP screen as seen by the camera lens. This window includes basic camera functions. The test pattern button when selected toggles to next test pattern from those available to system. A technician may have a preference to better evaluate the image and perform the alignment. The Restore default luminance settings button allows the user to restore the default iris opening value and lamp setting. Press this button if an incorrect iris setting is mistakenly entered. The Restore calibrated luminance settings button allows the user to restore the recently calibrated luminance iris opening value and lamp setting.




Figure 2-42 Night Luminance Page




2.3.6.5 Projector Settings

The Projector Settings page offers the capability to individually adjust projector parameters such as iris, contrast, brightness, RGB gain and bias in order to fine tune a selected projector so as to optimize the day and night scenes. The Projector Settings page includes the following buttons: • Projector selection • Night mode and Day mode • Brightness • Contrast • Iris control • R,G,B Gains (3 buttons – one for each color) • R,G,B Biases (3 buttons – one for each color) • Restore initial values • Restore calibrated values • Save The projector selection buttons located on left side of the page, allow the user to select a single projector to be adjusted or all projectors if the All channels button is pressed. Selecting the Day mode button restores and adjusts all projector settings for a day scene. In this mode, all other control buttons have effect on the day parameters. For example, restoring calibrated settings will only restore day values. Selecting the Night mode button restores and adjusts all projector settings for a night scene. In this mode, all other control buttons have effect on the night parameters. For example, restoring calibrated settings will only restore night values. The Iris control includes a left and right button. Selecting the left button decreases the iris opening, allowing less projector light (decreasing the light intensity); selecting the right button increases the iris opening, increasing the amount of projector light (increasing the light intensity). The brightness and contrast control buttons works in the same fashion as the iris button described just above. The Restore default settings button allows the user to restore the default day or night values. The Restore calibrated settings button allows the user to restore the calibration day or night values from the last save. The Save button allows the user to save the actual settings (values that are displayed) as new calibrated values. It also passes this information to the projector control (an application that is responsible for managing settings for day and night scene).

Start Up and Shutdown and Preventive Maintenance manuals for detailed visual system operation and maintenance and a complete listing and detailed presentation of procedures to maintain the visual system.

In addition to periodic and replacement procedures selected manual tuning procedures are presented under a separate subheading as they are particularly beneficial if spectrometer or camera is not available (broken or other reason). DDAT information is presented as follows:

• Prerequisites For Luminance and Color Alignment

• Calibrations To Integrate Specific Hardware (referenced in Table 5-2)

• Golden Alignment (procedures referenced in Table 5-1 and Table 5-2)

• Regular (Periodic) Maintenance (procedures referenced in Table 5-1)

• Manual adjustments (Color Correction, Luminance Match (Day) and Luminance Match (Night) are presented as these are beneficial if spectrometer or camera is not available)


Prerequisites For Luminance and Color Alignment 12 Apr 2010 Page 74


5.1 Prerequisites For Luminance and Color Alignment The following steps are necessary in order to run DDAT:

• Reboot the IGs via the CAE IG Main UI.

• Load IGs (only a load is desired, not a Load and Run) NOTE: Before Starting DDAT the CAE IG Main UI should be loaded

only (not running). • Verify that projector control is running.

• Start DDAT (Refer to Note below after ending a DDAT session).

NOTE: At the end of a DDAT session a reboot of the IGs is required to

reset the video cards. This may be done automatically (typical for NVIDIA platforms), if not a manual reboot is required (typical for ATI platforms) using the CAE IG Main UI.

On a new projector verify: • Projector settings (Sony VW60s - see Table 5-3, Sony GH10s - Table 5-4).

Set as required. • Convergence (Panel Alignment). • Projector alignment and geometry. • Blendplate alignment.

Unless otherwise indicated all calibrations are to be done in a darkened cockpit. NOTE: When using a light meter, avoid measuring close to cockpit window

edges. Left channels should be measured from the left seat and right channels from the right seat. Center channel (if applicable) should be measured from the pilot eye point.

Some visual systems have projectors that have lens clamp features. If this is the case ensure that lens clamps are loosened (clamp is released) to allow projector lens adjustment/movement before attempting any projector(s) calibrations. For systems with lens clamps refer to visual maintenance manual for details.


Selected Calibrations To Integrate Specific Hardware

12 Apr 2010 Page 75


5.2 Selected Calibrations To Integrate Specific Hardware When a visual system is being integrated for the first time or a projector, spectrometer, fiber optics item, or camera is being replaced the following is a standard approach to achieve optimum results. • Set Display Intensity. • Perform a Hardware Inspection – Calibration. • Set the projector Bias and Gain.

5.2.1 Set Display Intensity

This is an optional procedure that is necessary upon initial integration of a visual system and can be used to change mode (Maximum output versus constant light output) of operation of display system. (1) Select Lamp Management Configuration page (Home, Configuration,

Lamp Management Configuration). See Figure 5-1. NOTE: If prompted for password – enter the following password (maxvue

is a typical password that can be modifed) in lower case: maxvue

Figure 5-1 Lamp Management Configuration


Selected Calibrations To Integrate Specific Hardware 12 Apr 2010 Page 76


(2) Working from the Lamp Management Configuration menu page observe DDAT operation (either maximum output or constant luminance output).

(3) Select one of the following two options (default operation is maximum):

OPTION 1: Select Set to max button to obtain maximum balance

intensity that the lamp can provide. or

OPTION 2: Enter a value (6.1 for example) in Luminance correction

target box and press Enter. This will allow a constant luminance to be maintained as long as possible (a higher value (than 6.1) may be chosen).

(4) Select Back.

(4) Measure all blendzone edges and determine the dimmest channel.

NOTE: Avoid measuring close to cockpit window edges. Left blendzones should be measured from the left seat and right blendzones from the right seat.

(5) Select the dimmest projector and set the iris to 80 %. (6) Adjust the iris of the other projectors so that the luminance is within 2%

between adjacent channels.

• Use iris until 0 % then change the lamp power.

• Because of interchannel interaction, usually two iterations are required to achieve acceptable tolerances of 2% between adjacent channels.

• During the final adjustment the dimmest channel can be increased if

required. (7) Select Save settings for all channels. (8) Ensure cockpit is darkened and perform a Start reference acquisition.

• With a light meter, perform an intensity reading on the checker pattern

bright center square and enter dimmest reading in the message box and then select continue.

NOTE: Avoid measuring close to cockpit window edges. Left channels

should be measured from the left seat and right channels from the right seat. Center channel (if applicable) should be measured from the pilot eye point.

(9) Save results when asked. (10) Select Back to quit Day Luminance Reference menu.




5.3.2 Set Color Reference

For Sony VW60 projectors x=.299, y=.334. For Sony GH10 projectors x=.307, y=.335. (1) Select Color Reference page (Home, Configuration, Color Reference). See

Figure 5-7. NOTE: If prompted for password – enter the following password (maxvue

is a typical password that can be modifed) in lower case: maxvue

(2) Select All channels. (3) Select Restore default color settings.

(4) Select a channel.

(5) Measure the center square and adjust the RGB such that the desired color is

achieved (+/- 0.001). Do not go over 97% (248/255).

NOTE: Avoid measuring close to cockpit window edges. Left channels should be measured from the left seat and right channels from the right seat. Center channel (if applicable) should be measured from the pilot eye point.

(6) Repeat for other channels.

(7) Measure all channels again, and verify that stability has been reached.

• Note: There is interaction between channels.

(8) Select Save settings for all channels. (9) In a darkened cockpit select Start reference acquisition.

(10) Save results when asked.

(11) Select Home to quit Color Balance Reference menu.




5.3.3 Automatic Calibration

(1) Start Autocalibration – Initial calibration (Home, Calibration, Auto

Calibration, Initial calibration). NOTE: When this calibration is performed it will set a typical low end gamma

curve. Manual tuning may be required if the low end color and blendzone are not satisfactory, i.e. perform Color match at the Low end (night) procedure.

(2) Subjectively evaluate visually shades of grey pattern across all channels for a

good match between and across all channels. (3) Save results when prompted.

5.3.4 Luminance Match (Night)

(1) Select Night Luminance page (Home, Calibration, Manual Calibration, Night Luminance). See Figure 5-8.

Figure 5-8 Night Luminance Menu Page




(2) Select All channels.

(3) Select/switch to Full black field pattern. (4) Select Restore default luminance settings (All irises will be set to 0% and

the lamp power to low).

(5) Select a channel.

(6) Set lamp power to Low on Sony VW60 projector(s) or set lamp power to High on Sony GH10 projector(s).

(7) Subjectively evaluate the image and adjust the dimmest image to the brightest

image. Ensure that the brightest channel has its iris set to 0%. To do this find brightest projector, open irises of dimmer projectors until they are as bright as the brightest.

NOTE: Avoid evaluating close to cockpit window edges. Left channels

should be evaluated from the left seat and right channels from the right seat. Center channel (if applicable) should be evaluated from the pilot eye point.

(8) Select Save settings for all channels. (9) Quit Night Luminance menu.




5.3.5 Color Match at the Low End (Night)

The purpose of the gamma correction in general is to adjust the gamma of each projector Red, Green, and Blue colors individually, in order to obtain an overall uniform color and intensity match between channels and with least noticeable blendzones. Gamma adjustments are subjective and should be done from inside the flight compartment in total darkness. The technician’s eyes should be adapted to the environment prior to performing this correction (i.e. the eyes should not be exposed to light). The maintenance laptop intensity should be dimmed to minimum. In an ideal situation, one person should control the DDAT software while another person evaluates the projected image.





5.3.5.1 Adjust Color and Intensities of All Channels.

The overall channels correction consists in selecting predefined intensity points from the graph, evaluating the overall image of each channel and correcting projector(s) gamma individual colors to obtain an overall grey color across all channels. (1) Select Gamma Correction page (Home, Calibration, Manual Calibration,

Gamma). See Figure 5-9. Select the Dot mode and then Adjust channel. (2) Set correction level to 9. Subjectively evaluate intensity and color between

and across channels. Adjust intensity and color to obtain desired effect. NOTE: Distribute adjustment between channels to obtain desired result.

(3) Set correction level to 18. Subjectively evaluate intensity and color between and across channels. Adjust intensity and color to obtain desired effect. NOTE: Distribute adjustment between channels to obtain desired result.

(4) Repeat above for levels 29, 41, 54, and 77.

NOTE: Distribute adjustment between channels to obtain desired result.

5.3.5.2 Adjust Color and Intensities of the Blendzones.

The blend zone correction consists in setting the evaluation intensity at a certain level in order to evaluate the blend zone between channels, and correcting projector(s) gamma individual colors to obtain an overall grey color in the blendzone. (1) Select Gamma Correction page (Home, Calibration, Manual Calibration,

Gamma). See Figure 5-9. Select the Dot mode and then Adjust blendzone. (2) Set evaluation level to 18. Subjectively evaluate the blendzone and adjust

intensity and color to obtain desired effect.

NOTE: Adjust adjacent channels (up/down) to obtain desired result.

(3) Set evaluation level to 29. Subjectively evaluate the blendzone and adjust intensity and color to obtain desired effect.

NOTE: Adjust adjacent channels (up/down) to obtain desired result. (4) Repeat above for levels 41, 54, and 77. Subjectively evaluate the blendzone

and adjust intensity and color to obtain desired effect. NOTE: Adjust adjacent channels (up/down) to obtain desired result. (5) Select All channels, then select Save. Select Home to quit.
