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.
CIRCUIT OPERATIONS
1 Lens
Concentrates light rays to a point.
2 Color filter
The striped color filter in front of the CCD detector is used to provide color information.
It has three colors, yellow, green and cyan.
Array of color filter and signal processing (IC801) for camera are extremely close relationship.
