1. CCD
The CLC1000’s image input block is a 3-line CCD line sensor, each line consisting of 5000 photocells
(Figure 3-302). Each line is covered with a red, green, or blue color filter.
The light reflected by an original is projected to the CCD line sensor in reduced form, and the light color-
separated by the R, G, and B color filters is photo-converted. The signal charges occurring after conversion
are synchronized with the shift pulses generated by the analog processor PCB and stored temporarily in the
transfer block (single line); then, they are synchronized with the clock pulses generated by the analog
processor PCB and sent to the CCD in sequence.
Figure 3-302
The transfer block and the output block of each line sensor consist of an odd channel and an even
channel.
