6.2 Image Processing Circuit
(1) Outline
This digital copier scans optically the original placed on the original glass and reads an original image
using the CCD (charge coupled device), and converts the image into electrical signals. The electrical
signals are A/D converted into digital signals and output from the CCD board as image signals. The
image signals from the CCD board are input to the image processing section where shading correc-
tion (compensation for variance in the CCD or the light source) and various image-processing opera-
tions are performed. The results are output to the printer.
(2) Image Processing Circuit on the SLG Board
The SLG board contains an image processing ASIC which implements the following functions.
<Functions>
High quality image processing, image memory editing, editing processing, gamma correction pro-
cessing, tone processing and external output system interface
