II. OPTICAL SYSTEM

A. Outline

The optical system consists of the scanning lamp, lens and mirrors. When scanning areflective materials such as papers , the original is exposed to the light of the scanning lampin the scanning unit. The reflected light of the original forms an image on the photosensitivedevice, CCD (charge-coupled device) via lens and mirrors.

When scanning transparent material such as films, Light of the FAU lamp in the FilmAdapter Unit transmits the film. The transmitted light forms an image on CCD.

When scanning with FARE function, IR LED instead of FAU lamp works to operate FAREunit.

B. Lamp Lighting Circuit

1. Scanning Lamp Lighting Circuit

When the scanner is turned on, or the host computer sends a scan command, ASIC turnson the scanning lamp lighting signal (LAMP) to light the scanning lamp. The reflected light of the original is focused on CCD (charge-coupled device) via the fivemirrors, lens and FARE unit. The scanner is equipped with a lamp OFF function for energy saving. A built-in timerautomatically turns off the lamp if no scanning command is sent from the host computer fora certain period of time. Setting up of the timer is conducted by the device driver.

Figure 2-6

CHAPTER 2


2. FAU Lamp Lighting Circuit

Figure 2-7 is a FAU Lamp Lighting Circuit diagram.When the host computer sends a film scanning command, ASIC turns off the scanning lamplighting signal (LAMP) and simultaneously turns on FAU lamp lighting signal (XPA) to lightthe FAU lamp.

Light of the FAU lamp is converted into a flat light source by a light guide plate. The lightis diffused by the1st diffusive film, the luminous intensity enhancement film and the 2nddiffusive film. Light transmitted the transparent plate all has the same luminous intensity asa result. Light transmits a film and is focused on the CCD in the scanning unit.

The FAU lamp also has a lamp OFF function for energy saving.

3. Infrared LED Lighting Circuit

When the host computer sends a command to light an IR LED, ASIC turns on IRLED signalto light the IR LED. The IR LED light is converted into a flat light source by a light guide plate. Light transmitsa film via the1st diffusive film, the luminous intensity enhancement film, the 2nd diffusivefilm and the transparent plate.

C. FARE (Film Automatic Retouching and Enhancement)

1. Outline

When scanning a film, it is difficult to obtain a clean image because of dirt and scrach onthe film. CanoScan 9900F is equipped with the IR LED in addition to the FAU lamp (coldcathode fluorescent lamp) to remove scratches and dirt on a film by scanning a film by twolight sources. This function is called FARE (Film Automatic Retouching and Enhancement).

The IR LED scans only scratches and dirt on a film as image data. This data is compared tothe full image data scanned by the FAU lamp, and the overlap data (that is of scratches anddirt) is deleted. The other scanned data of the film compensates for the deleted area, andthe image without scratches and dirt is reproduced.

Figure 2-9-1 Figure 2-9-2 Figure 2-9-3

2. Operating FARE Function

Two light sources mounted in CanoScan 9900F have different frequencies ( the FAU lamp(cold cathode fluorescent lamp): 380- 700nm, and IR LED : 880nm). If there light sources areused under the same optical system, the image will be out of focus(Figure 2-9-2). CanoScan 9900F is equipped with FARE unit. This unit is placed between the CCD andlens and is consists of a refraction glass that changes the refractive index of light andelectromagnetic switch that change the position of the refraction glass.

First, scan a film with light of the FAU lamp transmitting the refraction glass. Secondl,scan a film with the IRLED and turn on the electromagnetic switch to move the refractionglass to the position where no IR LED light can transmit the glass (Figure 2-9-3). Above functions make it possible to obtain the scanned image with the focus of light on thefilm while using two light sources with different frequencies.

D. Motor Control Circuit

Figure 2-10 is a motor drive circuit diagram. Control program analizes a command sent from the host computer, and sends a motorclock generation command to ASIC. Gate array generates eight-phase motor drive pulsesignals [I01, I02, I11, I12, I21, I22, I31, I32]. These signals are sent to the drive motor viamotor driver.

When the host computer changes the resolution, the control program commands ASIC tochange the drive motor rotating speed by changing the frequency of the motor drive pulsesignal .

III. IMAGE PROCESSING

A. Outline

Image processing system consists of the CCD, analog IC, and ASIC. Analog signal read bythe CCD is converted into digital data, and the digital date is sent to the host computer.

Figure 2-11

B. Image Processing

1. CCD

The CCD is a single chip photoelectric conversion device equipped with several thousandphotosensitive devices. Each photosensitive devices is several microns square, and alldevices are formed into a line to read RGB image signals with a built-in scanning circuit. CanoScan 9900F uses 6-line CCD.

1) 6-line CCD 6-line CCD has two rows of photosensitive devices in staggered arrangement for RGB each.This measn that the image with the resolution worth 1600dpi x 2 = 3200dpi can be scannedby only one scanning operation.

Figure 2-12

To Host Computer1. CCD2. A/D

Conversion 3. Calibration 4. FilterProcessing

CHAPTER 2


1) D/A Converter D/A converter removes uneven data generated by the CCD' analog data. D/A converteradjusts CCD output to maintain a maximum value of input signal to A/D converter at 5V sothat the black level of the image be constant.

2) A/D Converter A/D converter converts the black-level-corrected image signal (analog signal) into a 16-bitimage data (digital signal) in the order of red, green and blue image signal.

CanoScan 9900F uses 8-bit A/D converter. 5V is applied to the Vcc terminal, and referencevoltage is applied to the Vref terminal. A/D converter outputs “0” when input signal is 5V,and outputs “255” when input signal equals to reference voltage. 1 pixel signal is convertedinto image data with 65536 tone for each colors including red, green and blue.

Figure 2-14

2. A/D Conversion Figure 2-13 is a block diagram that shows an internal processing of analog IC in the imageprocessing system. Output signal s from the CCD are analog signals, and they cannot be used as image data.So, RGB output signal from the CCD is amplified by analog amplifier to generate analog data.The data is then converted into image data by A/D converter.

CHAPTER 2


3. Calibration

When scanning a document of even density, the image signal corresponding to each pixelmay be uneven due to the following reasons:

* Uneven light intensity of the scanning lamp* Variation in the sensitivity of the light phototransistors* A slight output from the light phototransistors with no light

Calibration corrects these variations with the following three steps:Offset CalibrationCoarse-gain CalibrationProgrammable Gain Amplifier (PGA).

1) Offset Calibration Normalize the output data from each pixel at the value of 0 or near 0 by using data aquiredwith no light.

2) Coarse-Gain Calibration Finds the optimum gain setting to have the output voltage from all pixels within in theadjustment range of Programmable Gain Amplifier.

3) Programmable Gain Amplifier (PGA) Calculates a gain coefficient to make output constant by correcting the output differenceamong pixels.

4. Filter Processing

Changing the resolution and the scaling tends to reduce the image quality. To prevent this,the filter processing needs to be performed according to the resolution. The filter processingincludes interpolation processing and averaging.

CHAPTER 2


1) Interpolation Processing

When scanning at higher resolution, the image quality tends to be reduced. This is becauseone pixel output from the CCD is treated as two image data in the horizontal scanningdirection, and one line output of the CCD is treated as two image data in the verticalscanning direction. The interpolation processing is performed to prevent the image qualityreduction. Figure 2-15 shows a change in image density by the interpolation processing.

2) Averaging

When scanning at lower resolution, the quality of output tends to be deteriorated. This isbecause data thining occures more frequently at lower resolution. Averaging is a process toaverage the data to be thinned and the data to be actually output to prevent the imagedeterioration.
