CHAPTER 2
I. BASIC OPERATION
A. Functions
The scanner functions are divided into the following three main systems.
1. Optical System
The optical system consists of the scanning lamp, lens and mirrors. It exposes a document,
then the reflected light from the document is collected onto a light-sensitive device CCD
(charge-coupled device ) via the lens and mirrors.
2. Image Processing System
The image processing system consists mainly of the CCD, analog IC, and ASIC. It converts
analog signals from the CCD into digital signals, which is read by the host computer.
3. Control System
The control system consists mainly of ASIC, USB controller, CPU, and motor driver. The CPU
controls the whole scanning operation. The USB controller controls the interface between the
CPU and ASIC, while the CPU interprets all commands from the host computer.

B. Electrical System
1. Outline
The scanner is equipped with CPU and USB controller. Host computer sends a command to
the ASIC via the USB controller and CPU, the CPU controls the whole electrical circuits and
image processing of the scanner. The image signals read by the CCD are converted into digital
data by analog IC. The digital data are then processed by the ASIC and output to the host
computer via USB interface.

collecting the reflected light to the CCD. The system employs a 3-line CCD to recognize colors
of the document.

CHAPTER 2
A. Scanning Lamp
When the scanner is powered on, the scanning lamp lights to standby. The scanner is
provided with an energy saving setting which is made in the Scanner Utilities Dialog. For
example, if it is set for 30 minutes, then no scan command is sent for 30 minutes, ASIC sends
the scanning lamp off signal to turn off the lamp.

CHAPTER 2
B. Motor Control
When the host computer sends a command to change scaling/resolution, the motor driver
current control signals [PA+, PA-, PB+, PB-] are changed to generate a torque for the rotating
speed. Yet, the reverse speed of the scanning unit is always constant.
The ASIC receives each command sent from the host computer via the USB interface to
control the motor by four-phase motor driver pulse signals [OUT1B, OUT1A, OUT2A, OUT2B].

CHAPTER 2
B. Image Processing
1. Analog IC
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
2. 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.
3. A/D Converter
The A/D converter converts the black-level-corrected image signal (analog signal) to a 14-bit
image data (digital signal) in the order of red, green and blue image signal.
5V is applied to the VRT terminal and reference voltage is applied to the VRB terminal. A/D
converter outputs “0” when input signal is 5V, and outputs “16383” when input signal is
reference voltage. This converts 1 pixel signal into the image data of 16384 gradations for red,
green and blue each.

CHAPTER 2
C. Calibration
Calibration can be performed to normalize the pixels of a linear CCD so that each pixel
produces the same digital output code from the scanner when presented with the same image
light 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 when
scanning the same white image (corresponding to errors on brighter signals). If these offsets
are subtracted from each pixel, and each pixel is given the optimum gain setting to correct for
different efficiencies, then these errors can be eliminated.
Ideally the digital output code for any pixel would be zero for a black image, and some code
near 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 its
Correlated Double Sampling, Offset D/A converter, Variable Gain Amplifier (VGA), and
Programmable 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 to a code at or near
0.
2) Boot-Gain/Coarse-Gain Stage Calibration
Finds the optimum gain setting that places the output voltage of all the pixels from x0.93 to
x9 adjustment range of these two stages.
3) Shading Correction from ASIC
Calculates the gain required for normalizing the output of each pixel to the target code.

CHAPTER 2
D. 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 for this scanner includes horizontal scanning interpolation, vertical scanning
interpolation, descreen, and averaging. Table 2-2 shows the resolution for filter processing.

CHAPTER 2
E. 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 2-12 shows
a change in image density by the interpolation processing.

CHAPTER 2
F. 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.

CHAPTER 2
V. INTERFACE
A. Overview of the USB Standard
Since early 1997, the Universal Serial Bus (USB) has been the standard on most PCs. The
USB standard was developed by Compaq, IBM, Intel, Microsoft, NEC, and Northern Telecom. It
resulted from an industry-wide initiative to standardize peripheral attachments to PCs, and to
improve the speed, performance and ease of use of PC peripherals.
USB has been supported from Windows 95 (OSR 2.1), and it is now a key component of
Windows 98. In addition, USB are supported in Windows CE and Windows 2000 according to
Microsoft. USB support is currently available on the Apple platform and will be available
shortly on some other platforms.
B. Benefits of the USB Scanner
1. True Plug & Play
Unlike the previous generation of SCSI scanners, no add-in cards are required to setup the
USB 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 are
simply 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 12
Mbits/sec.
3. Multiple Devices Support
USB specification can support up to 127 devices simultaneously on a computer by using
“hub” terminals as additional plug-in locations.

CHAPTER 2
VI. POWER SUPPLY
DC power is supplied from a supplied AC adapter. Through power regulator, three DC power
sources (+5V, +12V and +15V) are used in the circuit. +5V is supplied for the digital circuit
and linear chip, +15V is for the CCD PCB, and +12V is for the motor driver and scanning lamp.
Protection circuit is used between the AC adapter and regulator to prevent over voltage, over
current or reverse polarity.

* Scan count
Set a number from 1 to 100.
* Resolution (dpi)
When the resolution for scanning an image is selected at 200, 300, 400, or 600 dpi, whole
document glass area is scanned. When selected at 1200 dpi, 10,280 pixel x 500 pixel area in
the upper side of the document glass is scanned.
* Image handling
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 for handling an scanned image,
the file of “img0.tif” is saved in the folder of the Canon Scanner Test. When scan count is set
at 2 or more, the file of “img0.tif”, “img1.tif”, “img2.tif” ... are saved.
File space to be saved is as follows.
200 dpi : 11.3 MB
300 dpi : 25.6 MB
400 dpi : 45.5 MB
600 dpi : 102.4 MB
1200 dpi : 14.6 MB
Note : Confirm before scanning that the available disk space on the HDD in which the
Canon Scanner Test is installed exceeds above file space.
