II. OPTICAL SYSTEM
A. Outline
The optical system consists of the scanning lamp, lens and mirrors. When scanning areflective document, the scanning lamp in the scanning unit exposes the document andfocuses the reflected light from the document on the light-sensitive device CCD (charge-coupleddevice) via the lens and mirrors.
When scanning a film, FAU lamp in the Film Adapter Unit transmits the film and focuses thetransmitted light on the CCD.
When using FARE system, infrared LED transmits a film after FAU lamp does, and FARE unitoperates to scan the film.

B. Lamp Lighting Circuit
1. Scanning Lamp Lighting Circuit
When the scanner is powered on, or the host computer sends a scan command, ASIC turnsthe scanning lamp lighting signal (LAMP) ON to light the scanning lamp. The reflected light from the document is focused on the light-sensitive device CCD (charge-coupled device) via the five mirrors, lens and FARE unit. The scanner is provided with a lamp OFF function for energy saving. A built-in timer to be setby the device driver is counted during lamp ON and turns the scanning lamp OFF when noscan command is sent for a certain period.

2. FAU Lamp Lighting Circuit
When the host computer sends a film scan command, ASIC turns the scanning lamp lightingsignal (LAMP) OFF then turns FAU lamp lighting signal (XPA) ON to light the FAU lamp.
The FAU lamp light is converted into a flat light source by a light guide plate, then diffused via1st diffusive film, brightness enhancement film and 2nd diffusive film. As a result, exposedlight from a transparent plate has equal light intensity which transmits a film and focuses onthe CCD in the scanning unit.
The FAU lamp also has a lamp OFF function for energy saving as in the case of the scanninglamp.
3. Infrared LED Lighting Circuit
When the host computer sends a command to light an infrared LED, ASIC turns IRLED signalON to light the infrared LED. The infrared LED light is converted into a flat light source by a light guide plate as in the caseof the FAU lamp, which transmits a film via 1st diffusive film, brightness enhancement film,2nd diffusive film and transparent plate.

C. FARE (Film Automatic Retouching and Enhancement)
1. Outline
FAU-S13 attached to D2400U employs an infrared LED in addition to the FAU lamp (coldcathode fluorescent lamp) in order to remove scratches and dirt on a film by transmitting a filmby two light sources. This system is called FARE (Film Automatic Retouching andEnhancement).
The infrared LED scans only scratches and dirt on a film as image data. This image data iscompared to the full image data scanned by the FAU lamp, and the overlapping data ofscratches and dirt is subtracted, then this area is compensated for by sampling the ambientdata. Accordingly, the image without scratches and dirt is reproduced.

2. Operation of FARE system
The frequency of the FAU lamp (cold cathode fluorescent lamp) is 380-700nm, while that ofthe infrared LED is 880nm, therefore, their light refractive indexes differ resulting in out offocus (Figure 2-10-2). As a solution, D2400U employs FARE unit between the CCD and lens, which consists of arefraction glass for changing the light refractive index and of an electromagnetic switch forchanging the position of the refraction glass. Firstly, the FAU lamp scans a film passing through the refraction glass. Secondly, theinfrared LED scans a film, at the same time, the electromagnetic switch is turned ON to movethe refraction glass to the position where the infrared LED light does not pass through (Figure2-10-3). Finally, the FAU lamp and infrared LED can scan a properly focused film.

D. Motor Control Circuit
Control program analizes a command sent from the host computer, and sends a motor clockgeneration command to ASIC. Gate array generates four-phase motor drive pulse signals [I01,I11, I02, I12], which are sent to the drive motor via motor driver.
When the host computer sends a command to change scaling/resolution, the control programcommands the ASIC to change the frequency of the motor drive pulse signal to change thedrive motor rotating speed.

1. CCD
The CCD is a single chip photoelectric conversion device which consists of several thousandphotosensitive devices of each several microns square, for reading RGB image signals, with abuilt-in scanning circuit. D1230U employs 3-line CCD, and D2400U employs 6-line CCD.
1) 6-line CCD 6-line CCD has two rows of staggered photosensitive devices for RGB each. The 6-line CCDtherefore can scan at 1200dpi x 2 = 2400dpi.

1) D/A Converter D/A converter removes ununiform analog data generated by the CCD. It adjusts CCD outputto keep max. 5V of input signal to the A/D converter, to make the black level of the imageconstant.
2) A/D Converter The A/D converter converts the black-level-corrected image signal (analog signal) to a 16-bitimage data (digital signal) in the order of red, green and blue image signal.
5V is applied to the Vcc terminal and reference voltage is applied to the Vref terminal. A/Dconverter outputs “0” when input signal is 5V, and outputs “65535” when input signal isreference voltage. This converts 1 pixel signal into the image data of 65536 gradations for red,green and blue each.

2. A/D Conversion
Output signal from the CCD is an analog signal which cannot be used as image data. So RGBoutput signal from the CCD is amplified by analog amplifier to generate analog data. Thegenerated data is converted into averaged analog signal by D/A converter, then got feedback tothe A/D converter to output constant digital data to the ASIC.

3. Calibration
Calibration can be performed to normalize the pixels of a linear CCD so that each pixelproduces the same digital output code from the scanner when presented with the same imagelight intensity. This intensity ranges from black (no light) to white (maximum light intensity).The CCD’s analog output may have large pixel-to-pixel variations in their output voltage whenscanning the same white image (corresponding to errors on brighter signals). If these offsetsare subtracted from each pixel, and each pixel is given the optimum gain setting to correct fordifferent efficiencies, then these errors can be eliminated.
Ideally the digital output code for any pixel would be zero for a black image, and some codenear the full scale for an image with maximum brightness. This code is called the target code.
The analog IC eliminates these global and pixel-to-pixel offset and gain errors with itsCorrelated Double Sampling, Offset D/A converter, Variable Gain Amplifier (VGA), andProgrammable Gain Amplifier (PGA).
Calibrating an analog IC-based system requires three steps:
1) Offset Calibration Takes a black image and normalizes the digital output code for each pixel at or near 0.
2) Boot-Gain/Coarse-Gain Stage Calibration Finds the optimum gain setting that places the output voltage from all pixels from x0.93 to x9adjustment range of these two stages.
3) Shading Correction from ASIC Calculates the gain required for normalizing the output from each pixel to the target code.
4. Filter Processing
When converting resolution and scaling, the image quality tends to be reduced. To preventthe image quality reduction, filter processing is performed according to the resolution. Filterprocessing includes interpolation processing and averaging.

1) Interpolation Processing
When reading images at higher resolution, the one pixel output of the CCD is treated as twoimage data in the horizontal scanning direction, and the one line output of the CCD is treatedas two image data in the vertical scanning direction, causing a reduced image quality. Toprevent the image quality reduction, interpolation processing is performed. Figure 2-16 showsa change in image density by the interpolation processing.

2) Averaging
When reading images at lower resolution, the thinned data increases resulting in outputimage deterioration. Averaging is a process in which the data to be thinned and the data to beactually output are averaged and output, in order to suppress the image deterioration due tothe data thinning.

5. Binary Processing
Binary processing converts the 8-bit grayscale data into binary data in which 1 bit indicateswhite or black.
Figure 2-18
The ASIC sets parameters (slice level) in the slice level register when the host computercommands binary processing. The comparator compares the image data with the slice level,and converts the data into binary data consisting of 1 (black) or 0 (white).

V. INTERFACE
A. Outline of USB Standard
Since early 1997, the Universal Serial Bus (USB) has been the standard on most PCs. TheUSB standard was developed by Compaq, IBM, Intel, Microsoft, NEC, and Northern Telecom. Itresulted from an industry-wide initiative to standardize peripheral attachments to PCs, and toimprove the speed, performance and ease of use of PC peripherals.
B. Benefits of USB Scanner
1. True Plug & Play Unlike the previous generation of SCSI scanners, no add-in cards are required to setup theUSB scanners. This eliminates complex procedures, such as opening the box to install a card,or reconfiguring the system (setting DMA, IRQ, jumper cables, etc.) The USB scanners aresimply plugged in and unplugged at any time.
2. Higher Speed USB scanner is nearly 10 times faster than a standard parallel-port scanner at bandwidth 12Mbits/sec. for data transfer.
3. Multiple Devices Support USB specification can support up to 127 devices simultaneously on a computer by using“hub” terminals as additional plug-in ports.
