CHAPTER 2
II. OPTICAL SYSTEM
A. Outline
When scanning are flective document, the scanning lamp in the scanning unit exposes the
document and focuses the reflected light from the document on the CCD. When scanning a
film at 601 dpi or higher using FAU, FAU lamp built in the document cover exposes the film,
and optical axis is shifted by a half pixel in the horizontal scanning direction by means of
VAROS unit, and the images before and after the optical axis is shifted are composed by the
host computer.

CHAPTER 2
B. VAROS
1. VAROS operation
VAROS is short for Variable Refraction Optical System. Refraction glass is placed between the
CCD and lens, and the direction of the refraction glass is moved to change the optical axis
thus changing the scanning position. When the host computer commands 601 dpi or higher
resolution to scan a film using FAU, two image data before and after the direction of the
refraction glass is moved are composed to make double image data. The resolution when using
VAROS is always 1200 dpi regardless of the command from the host computer.
The drive motor runs by the drive signal sent from the ASIC and drives the scanning unit via
the belt.

CHAPTER 2
2. Scanning by means of VAROS
There placed in order of the CCD, refraction glass, lens, and mirrors in the scanning unit.
The refraction glass is equipped with a solenoid to control the direction of the refraction glass.
When the host computer commands 601 dpi or higher resolution to scan a film using FAU, the
ASIC selects to use VAROS for scanning.
Firstly scans before moving the direction of the refraction glass at 600 dpi in the horizontal
scanning direction and 1200 dpi in the vertical scanning direction. The scanned image data is
stored in the host computer as a temporary data.

CHAPTER 2
After the 1st scan, the ASIC turns signal ON to drive the solenoid to change the direction of
the refraction glass. Changing the direction of the refraction glass shifts the optical axis from
the CCD to a film by a half pixel. Therefore, the 2nd scan is performed between the pixels of
the 1st scan.

These image data are composed in the host computer to output 1200 x 1200 dpi image data.
When the ASIC commands between 601 dpi and 1199 dpi, scan is performed at 1200 dpi, then
the host computer performs resolution conversion to output the image data conforming to the
command by the ASIC.

CHAPTER 2
C. Scanning lamp/FAU lamp lighting circuit
When the scanner is powered ON, the "LAMP ON" signal is set to "H" and turns ON the lamp
control circuit to provide +12VI to the inverter PCB to light the scanning lamp.
The scanning lamp exposure control is performed by scanning white calibration plate which
is placed outside the image area to feedback on the output. ASIC inputs the pulse signal
(LAMP ON) according to the feedbacked signal to the lamp control circuit to generate +12VI.
FAU lamp exposure control is performed by directly feedbacking the output from the FAU
lamp. When the host computer commands to use the FAU, ASIC sets "FAU INV" signal to "H".

D. Drive Motor Control Circuit
When the host computer sends a command to change scaling/resolution, the ASIC generates
the control signal (A+, A-, B+, B-) and sends the signal to the drive motor via the motor driver.
When the host computer changes its command to the ASIC, the ASIC changes its control
signal to control the motor driver.

CHAPTER 2
III. IMAGE PROCESSING SYSTEM
A. Outline
The image processing system converts analog image signals read by the CCD into digital
data, performs various image processing, then outputs the data to the host computer via USB
port. Shading correction and gamma correction are performed by the driver software instead of
the scanner function.

B. Image Processing Functions
1. CCD
The ASIC outputs clock signals based on the command from the host computer to the CCD.
The scanner uses a 3 line CCD to read the color signals. The 3 line CCD is a single chip
photoelectric conversion device which consists of 3 lines of several thousand photosensitive
devices, each several microns square, reading for red, green, and blue analog image signals,
and of a scanning circuit.
Blue photosensitive section
Green photosensitive section
Red photosensitive section
Figure 2-15
2. A/D conversion
Analog image signals output from the CCD are converted into the digital data of 14 bits each
by A/D converter in the ASIC in order of red, green, and blue image signals.

CANOSCAN D660U REV.0 JULY 2000 PRINTED IN JAPAN (IMPRIME AU JAPON)
CHAPTER 2
3. Shading correction
When the CCD reads a document of even density, the image signal corresponding to each
pixel is not uniform for the following reasons.
1) Light intensity of the scanning lamp is not uniform.
2) There is variation in the sensitivity of the light phototransistors.
3) There is a slight output from the light phototransistors even when there is no input.
These variations are corrected by the shading correction. Calibration data is used as
standard density data when scanning a document. Scanned image data is compared to the
standard density data for the image data correction.
4. Gamma correction
Shading-corrected red, green and blue image data are divided uniformly into 16384
gradations according to the document density. The contrast and density of this image data are
adjusted by the gamma correction. The ASIC writes gamma curve specified by the host
computer into the buffer RAM before scanning a document. Image scan starts and the image
data input to the buffer RAM is converted by the gamma curve data and is output.
5. Resolution conversion
1) Resolution conversion in the horizontal scanning direction
Basic resolution is 600 dpi, and selective at 600 dpi, 300 dpi, 150 dpi, and 75 dpi.
Resolution conversion in the horizontal scanning direction is performed by averaging the
image data of the basic resolution as shown in Figure 2-16.

CHAPTER 2
2) Resolution conversion in the vertical scanning direction
The ASIC changes the scanning unit moving speed to change the resolution in the vertical
scanning direction. When increasing the resolution, the scanning unit moves at a low speed to
read more lines as shown in Figure 2-18.

CHAPTER 2
IV. CONTROL SYSTEM
A. Outline
CanoScan D660U is not equipped with the CPU and the scanner is controlled by the device
driver installed in the host computer. The device driver includes the scanner control program,
which sets a command directly to the ASIC to control the scanner.
B. USB Interface
The scanner is connected to the host computer via USB interface. USB (Universal Serial
Bus) is the next generation general-purpose input-output interface to connect the computer
peripheral devices.
1. Features of USB includes;
* Connects peripheral devices by a tree structure.
* Connects up to 127 devices by a tree structure.
* Connects by 12 Mbps of "full speed mode" or 1.5 Mbps of "low speed mode". The scanner is
conforming to "full speed mode".
* Supports hot plug (able to connect/disconnect with the power ON)
2. Connection to USB devices
USB devices are connected to a host computer by a tree structure consisting of device called
"node" and "hub" which is a group of "node" as shown in Figure 2-20. The tree structure has
the following conditions.
* Able to connect up to 127 "node" and "hub" in total.
* Limited up to 6 layers.
* USB cable must be 5 meters or shorter.

3. USB data transfer
*
*
*
*
USB data is transferred in the following four data structures called "packet".
Token packet
: Used to start a data transfer
Handshake packet
: Used to report the status of a data transfer
Data packet
: Used to send and receive data
Special packet
: Used for other transfer
USB device may support multiple data transfer endpoints, so there are four types of data
transfer protocols.
* Isochronous transfer : Allocates a data transfer time to a device. Highest priority is given but
no error is corrected.
* Interrupt transfer
: Periodically transfers data within a specified waiting time. Second
priority is given.
* Control transfer
: Used to configure the host computer when USB device is attached/
removed.
* Bulk transfer
: Lowest priority is given but larger amounts of data is sequentially
transferred to a free bus.

CHAPTER 2
V. POWER SUPPLY
AC adapter is supplied for the scanner power source. The AC adapter converts the AC power
into +12VDC. The output DC power is converted into +5VDC in the main PCB. +5VDC is used
for the IC in the main PCB. +12VDC is supplied to the CCD and drive motor.
Protection circuit is built-in the main PCB to prevent overvoltage or reverse polarity. The
protection circuit is composed of a fuse and zener diode. If overvoltage or reverse polarity is
input, the fuse burns to protect a further circuit.
