    CIRCUIT OPERATIONS 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.
  • Page 6 3 CCD (IC802) A charge-coupled device in which charges are introduced when light from a scene is focused on the surface of the device. The image points are accessed sequentially to produce a television-type output signal. Effective picture element: 249,936 = 508 (H) x 492 (V) 532(H) 508(H) PHIS1~PHIS4:...
