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.
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.

Battery
Digital PCB is composed Microprocessor (IC600), D RAM (IC601), Flash Memory (IC602),
Gate Array (IC700), and V RAM (IC701).
Microprocessor controls the CCD, D RAM, Flash Memory and key operation. Gate array
compresses data for the color and the luminance from the CCD to increase the number of
memory, and up to 96 images can be stored in flash memory. The color and the luminance
data are mixed in the gate array to make the video signal.
As to spare parts for digital PCB, Casio supplies PCB ass'y and the individual parts.

The color difference and the luminance data is compressed about 1/7 to increase the
numer of images in memory. Up to 96 images can be stored.

Cb (color difference signal B-Y) data : 160 x 112 byte 21,120 byte
Cr (color difference signal R-Y) data : 160 x 112 byte 1/7
Total: 143,360 byte 21,120 byte
Encoder
The color and the luminance data are mixed internally to make the video signal, and
send it to the linear PCB and the video out terminal.

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.

5 D RAM
There is area of work space that the microprocessor uses for storing temporary data , the
intermediate results of calculations, and all sorts of pieces of information that the system
needs to remember.
Each picture element electrode is controlled by a transistor. To the gate electrodes, the
gate pulse is applied timesharing. VCOM voltage is applied to the common electrodes.
The above figure shows the operation of TFT-LCD. If the gate pulse is not applied to
the gate electrodes, the transistors do not operate even when the potential difference
is given between the common electrodes and source electrodes, and no effect is given
to the liquid crystal. If the gate pulse is applied to Y1, the transistorT1 is in operation
during a priod of t1, and voltage of source electrode of Va is applied to the LCD layer
of picture element A, then electric charges are stored in the picture element of A. After
the period of t1, T1 is turned off, and voltage in the LCD layer of A is held until next
gate pulse comes, but it drops little by little through off leak resistance of TFT and leak
resistance of LCD itself.
BACK LIGHT
The camera unit is equipped with a fluorescent light source to provide the back lighting
for its LCD. The normal service life of the backlight is approximately six years, when the
camera is used for about two hours a day.
The backlight is consumption items, so even under guarantee replace it under charge
basis.

V COM Adjustment
The V COM adjustment is required whenever replacing the TFT-LCD. This adjustment is same as the V
COM adjustment of the TFT-LCD television.
Color Adjustment
The color adjustment is required when the camera unit or the Digital PCB unit is replaced, because of the
change of the CCD characteristic.
The following items are required for the color adjustment.
