CHAPTER 2 I. BASIC OPERATION A. Functions The scanner functions are divided into optical system, image processing system, and control system. FAU FAU Lamp IR LED BGR Scanning Lamp Scanning unit Lens B G R CCD Host Computer Optical System FARE Unit Control System Drive Motor Image Processing System Figure 2-1 COPYRIGHT © 2001 CANON INC. CANOSCAN D1230U/D2400U REV.0 MAR.
CHAPTER 2 B. Electrical System 1. Outline The scanner is not equipped with CPU. The device driver installed in the host computer includes a control program, which functions as CPU. Host computer sends a command to the ASIC via the USB controller, the ASIC 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 is then processed by the ASIC and output to the host computer via USB interface.
CHAPTER 2 2. Functions of the Main PCB 1) Analog IC Converts the image signals (analog signals) read by the CCD into digital data.
CHAPTER 2 C. Main PCB Input and Output 1.
CHAPTER 2 2.
CHAPTER 2 D.
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.
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 (chargecoupled device) via the five mirrors, lens and FARE unit. The scanner is provided with a lamp OFF function for energy saving.
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.
CHAPTER 2 C. FARE (Film Automatic Retouching and Enhancement) 1. Outline FAU-S13 attached to D2400U 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 system is called FARE (Film Automatic Retouching and Enhancement). The infrared LED scans only scratches and dirt on a film as image data.
CHAPTER 2 2. Operation of FARE system 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 2-10-2). As a solution, D2400U employs FARE unit between the CCD and lens, which consists of a refraction glass for changing the light refractive index and of an electromagnetic switch for changing the position of the refraction glass.
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 scaling/resolution, the control program commands the ASIC to change the frequency of the motor drive pulse signal to change the drive motor rotating speed.
CHAPTER 2 III. IMAGE PROCESSING A. Outline Image processing system consists of the CCD, analog IC, and ASIC. Analog signals read by the CCD is converted into digital data, then output to the host computer. Blue Image data Processing 6. Image Inversion Green Image data Processing 1. CCD 2. A/D Conversion 3. Calibration 4. Filter Processing 5. Binary Processing Red Image data Processing 6. Image Inversion To Host Computer 6. Image Inversion Figure 2-12 B. Image Processing 1.
CHAPTER 2 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 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).
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 2-16 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.
CHAPTER 2 5. Binary Processing Binary processing converts the 8-bit grayscale data into binary data in which 1 bit indicates white or black. 255 254 . . . 129 128 127 126 . . . 1 0 Slice level Document Binary processing Image data (8 bits) 1 1 . . . 1 1 0 0 . . . 0 0 Binary data (1 bit) Output image Figure 2-18 The ASIC sets parameters (slice level) in the slice level register when the host computer commands binary processing.
CHAPTER 2 6. Image Inversion (negative/positive) Image inversion is to reverse the density level of a document by inverting the color data, 8-bit grayscale data or binary data. Image Inversion ABC ABC Document Image Output Figure 2-20 COPYRIGHT © 2001 CANON INC. CANOSCAN D1230U/D2400U REV.0 MAR.
