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.

OPTICAL SYSTEM The optical system has functions from exposing a document by the scanning lamp to collecting the reflected light to the CCD. The system employs a 3-line CCD to recognize colors of the document. CCD Lens Scanning Lamp LTR A4 B5 B5 R LT A4 Figure 2-6 COPYRIGHT © 2000 CANON INC.

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.

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].

CANOSCAN FB1210U REV.0 APR. 2000 PRINTED IN JAPAN (IMPRIME AU JAPON) 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. D/A Converter CCD R G B Analog Amplifier A/D Converter Digital data To ASIC Analog IC Figure 2-10 COPYRIGHT © 2000 CANON INC. CANOSCAN FB1210U REV.0 APR. 2000 PRINTED IN JAPAN (IMPRIME AU JAPON) 2 - 11 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.

CANOSCAN FB1210U REV.0 APR. 2000 PRINTED IN JAPAN (IMPRIME AU JAPON) 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.

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. Gradation Color Grayscale Vertical scanning interpolation Descreen Averaging 10-99 Horizontal scanning interpolation x x o x 100 x o o x 101-149 x x o x 150 x o o x 151-299 o x o o 300 x o x x 301-1200 o x x x 10-149 x x o x Resolution (dpi) 150 o x o x 151-299 o x o o 300 x x x x 301-1200 o x x x Table 2-2 2 - 14 COPYRIGHT © 2000 CANON INC. CANOSCAN FB1210U REV.0 APR. 2000 PRINTED IN JAPAN (IMPRIME AU JAPON) 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.

CANOSCAN FB1210U REV.0 APR. 2000 PRINTED IN JAPAN (IMPRIME AU JAPON) 2 - 15 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.

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. 2 - 20 COPYRIGHT © 2000 CANON INC.

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.
