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.

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:...

3 V RAM It is used for encoder function. 4 Flash Memory Up to 96 images can be stored in memory. Flash memory does not require electrical power to store data, so image data is retained in memory even when you turn camera power off. If batteries go dead, simply load a set of new batteries or connect the AC adaptor and you will be able to view images in camera memory.
