CHAPTER 2


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.

Figure 2-5

CHAPTER 2


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.

CHAPTER 2


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.

CHAPTER 2


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.

CHAPTER 2


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.

Figure 2-12

Conversion 3. Calibration 4. FilterProcessing



CHAPTER 2


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.

CHAPTER 2


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.



CHAPTER 2


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.

CHAPTER 2


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.
