Picture Signal Scanning Block
The image data read by the optical unit is input to the CCD mounted on the CCD PC Board, then transferred to the FCB PC Board
after the optical information is converted into an electrical signal by the CCD. The following shows a block diagram of the picture
signal scanning circuit. This picture signal scanning circuit consists of (1) ABC circuit, (2) shading correction circuit, (3) offset con-
trol circuit, (4) picture signal binary coding correction circuit and (5) reducing circuit.
