II. OPTICAL SYSTEM
A. Outline
The optical system consists of the scanning lamp, lens and mirrors. When scanning a
reflective document, the scanning lamp in the scanning unit exposes the document and
focuses the reflected light from the document on the light-sensitive device CCD (charge-
coupled device) via the lens and mirrors.
When scanning a film, FAU lamp in the Film Adapter Unit transmits the film and focuses the
transmitted light on the CCD.
When using FARE function, infrared LED transmits a film after FAU lamp does, and FARE
unit operates 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 turns
the 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
set by the device driver is counted during lamp ON and turns the scanning lamp OFF when
no scan 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
lighting signal (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
via 1st diffusive film, brightness enhancement film and 2nd diffusive film. As a result,
exposed light from a transparent plate has equal light intensity which transmits a film and
focuses on the CCD in the scanning unit.
The FAU lamp also has a lamp OFF function for energy saving as in the case of the scanning
lamp.
3. Infrared LED Lighting Circuit
When the host computer sends a command to light an infrared LED, ASIC turns IRLEDsignal ON to light the infrared LED.
The infrared LED light is converted into a flat light source by a light guide plate as in the
case of 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
CanoScan 8000F employs an infrared LED in addition to the FAU lamp (cold cathode
fluorescent lamp) in order to remove scratches and dirt on a film by transmitting a film by
two light sources. This function is called FARE (Film Automatic Retouching and
Enhancement).
The infrared LED scans only scratches and dirt on a film as image data. This image data is
compared to the full image data scanned by the FAU lamp, and the overlapping data of
scratches and dirt is subtracted, then this area is compensated for by sampling the ambient
data. Accordingly, the image without scratches and dirt is reproduced.

Figure 2-9-1 Figure 2-9-2 Figure 2-9-3
2. Operation of FARE Function
The frequency of the FAU lamp (cold cathode fluorescent lamp) is 380-700nm, while that of
the infrared LED is 880nm, therefore, their light refractive indexes differ resulting in out of
focus (Figure 2-9-2).
As a solution, CanoScan 8000F employs FARE unit between the CCD and lens, whichconsists of a refraction glass for changing the light refractive index and of an electromagnetic
switch for changing the position of the refraction glass.
Firstly, the FAU lamp scans a film passing through the refraction glass. Secondly, the
infrared LED scans a film, at the same time, the electromagnetic switch is turned ON to move
the refraction glass to the position where the infrared LED light does not pass through
(Figure 2-9-3).
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
clock generation 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 resolution, the control program
commands the ASIC to change the frequency of the motor drive pulse signal to change the
drive motor rotating speed.

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, then output to the host computer.
Figure 2-11
B. Image Processing
1. CCD
The CCD is a single chip photoelectric conversion device which consists of several
thousand photosensitive devices of each several microns square, for reading RGB image
signals, with a built-in scanning circuit.
CanoScan 8000F employs 6-line CCD.
1) 6-line CCD
6-line CCD has two rows of staggered photosensitive devices for RGB each. The 6-line CCD
therefore 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 output
to keep max. 5V of input signal to the A/D converter, to make the black level of the image
constant.
2) A/D Converter
The A/D converter converts the black-level-corrected image signal (analog signal) to a 16-bit
image 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/D
converter outputs “0” when input signal is 5V, and outputs “255” when input signal is
reference voltage. This converts 1 pixel signal into the image data of 65536 gradations for
red, green and blue each.
Figure 2-14
2. A/D Conversion
Output signal from the CCD is an analog signal which cannot be used as image data. So
RGB output signal from the CCD is amplified by analog amplifier to generate analog data.
The generated data is converted into averaged analog signal by D/A converter, then got
feedback to the A/D converter to output constant digital data to the ASIC.

3. Calibration
When CCD reads a document of even density, the image signal corresponding to each pixel
is not uniform for the following reasons.
* Light intensity of the scanning lamp is not uniform.
* There is variation in the sensitivity of the light phototransistors.
* There is a slight output from the light phototransistors even when no data is input.
These variations are corrected by the calibration in three steps of Offset calibration, Coarse-
gain calibration, and Programmable Gain Amplifier (PGA).
1) Offset Calibration
Takes output data when no data is input and normalizes the output data from each pixel at
or near 0.
2) Coarse-Gain Calibration
Finds the optimum gain setting for placing the output voltage from all pixels in the
adjustment range of Programmable Gain Amplifier.
3) Programmable Gain Amplifier (PGA)
Calculates a gain coefficient for uniforming the output by correcting the output difference
among pixels.
4. Filter Processing
When converting resolution and scaling, the image quality tends to be reduced. To prevent
the image quality reduction, filter processing is performed according to the resolution. Filter
processing includes interpolation processing and averaging.

1) Interpolation Processing
When reading images at higher resolution, the one pixel output of the CCD is treated as two
image data in the horizontal scanning direction, and the one line output of the CCD is
treated as two image data in the vertical scanning direction, causing a reduced image quality.
To prevent the image quality reduction, interpolation processing is performed. Figure 2-15
shows a change in image density by the interpolation processing.

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

Figure 5-14.)
* Scan count
Set a number from 1 to 100. When 2 or more is set and "Save to TIFF file" is selected, only
a file of specified count is saved.

When “Read in memory (no file)” is selected, the image is read into the memory, then
abandoned after readout. When “Save to TIFF file” is selected, two image files scanned by
FAU lamp and IR LED are saved. "Color24_0.tif" and "IR_0.tif" are saved in the folder of the Canon Scanner Test. IR.tif is an image of only dirt or dust on the film when FARE function is
used. If FARE function does not normally work, IR.tif image appears all black. When scan
count is set at 2 or more, the file of Color24_0.tif/IR_0.tif, Color24_1.tif/IR_1.tif... are saved.
File space to be saved is as follows.
Color24_0.tif (1200 dpi) : 5.6 MB, IR_0.tif (1200 dpi) : 5.6 MB
Note: When scanning a film, the scanned image is lighter in color than the original film,
because the image is not subjected to the image processing yet.
