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: Clock pulse for the storage. Image pickup PHI1~PHI4: Clock pulse for the image pickup. 19 18 17 16 PHIH1~PHIH2: Clock pulse for the horizontal shift register. PHIR: CCD analog signal output.

COLOR ADJUSTMENT Each of this model has a color information in its flash memory due to the CCD camera has a color characteristic. The color information is loaded in the flash memory when the color adjustment is done after assembling of this model in our factory. A brand-new flash memory and digital PCB ass’y stocked in our spare parts center do not have the color information, so the color adjustment should be done after the following situation.
Execution of the color adjustment 1. Set the aperture switch to F8 position, and turn on QV-30. F2.8 MACRO F8 NORMAL 2. Put the color filter on the light source, and turn on the light box. Color filter: LBA 3 Light box: Handy 5000 3. Put the QV-30 with its lens toward the light source. PC QV-30 4. Execute “ADJ724.EXE” on MS-DOS. Type “ADJ724” and press Enter. The message “WAIT” appears on the monitor of QV-30.
