5.3.6.3 CCD Drive <iR7105/7095>
0011-2249
1. CCD
The CCD used in the machine is a 1-line linear image sensor.
- Number of pixels: 7400
- Size of a pixel: 4.7 x 4.7 ym
2. CCD Drive
The signals converted by the light-receiving block are sent out in 2 analog video signal channels (even-
numbered pixels, odd-numbered pixels).
