6.3.6 Image Processing
6.3.6.1 Overview
The following shows the major functions of the machine' s image processing system:
- CCD (image sensor)
number of lines: 3 (RGB, 1 line each)
number of pixels: 7350
size of pixel: 9.3 x 9.3 ym
- Shading Correction shading adjustment: in service mode
shading correction: performed for every copy
F-6-31
The following shows the functions of the PCBs associated with the image processing system:
CCD/AP PCB: CCD drive, analog image processing, A/D conversion
reader controller PCB: shading correction
The machine performs image processing for every RGB line using the reader controller PCB, and the major
functions involved are as follows:
(1) Analog Image processing
(a) CCD drive
(b) CCD output gain correction, offset correction
(c) CCD output A/D conversion
