CAMERA UNIT (CAMERA PCB)

The camera unit is composed a lens, color filter, CCD (IC802), driver (IC800) and signal processor (IC802).

It produces voltages R, B, and G, for the colors red, blue, and green when light from a scene is focused on

the surface. These voltage values vary according to the intensity of the respective color being scanned.

The camera unit must be replaced with whole unit when it is defective, because the precise adjustment is

required when the individual parts are replaced, and can be done only at our factory.
