5. Transfer of Electric Charge by the Horizontal CCD
The transfer system for the horizontal CCD emplays a 2-phase drive method.
The electric charges sent to the final stage of the horizontal CCD are transferred to the floating diffusion, as shown in Fig. 1-5.
RG is turned on by the timing in (1), and the floating diffusion is charged to the potential of PD. The RG is turned off by the timing
in (2). In this condition, the floating diffusion is floated at high impedance. The H1 potential becomes shallow by the timing in (3),
and the electric charge now moves to the floating diffusion.
Here, the electric charges are converted into voltages at the rate of V = Q/C by the equivalent capacitance C of the floating
diffusion. RG is then turned on again by the timing in (1) when the H1 potential becomes deep.
Thus, the potential of the floating diffusion changes in proportion to the quantity of transferred electric charge, and becomes

3. LCD Block
During EE, gamma conversion is carried out for the 10-bit
RGB data which is input from the A/D conversion block of the
CCD to the ASIC in order that the revised can be displayed
on the video. The YUV of 640 x 480 is then transferred to the
SVRAM.
The data which has accumulated in the SDRAM is after D/A
conversion is carried out by SDRAM control circuit inside the
ASIC , makes Y/C signal, the data is sent to the LCD panel
and displayed.
If the shutter button is pressed in this condition, the 10-bit
data which is output from the A/D conversion block of the
CCD is sent to the SDRAM (DMA transfer), and is displayed
on the LCD as a freeze-frame image.
During playback, the JPEG image data which has accumu-
lated in the SSFDC card is converted to RGB signals. In the
same way as for EE, the data is then sent to the SDRAM,
after which D/A conversion is carried out inside the ASIC,
and then the data is sent to the LCD panel and displayed.
The LCD driver is converted Y/C signals to RGB signals from
ASIC, and these RGB signals and the control signal which is
output by the LCD driver are used to drive the LCD panel.
The RGB signals are 1H transposed so that no DC compo-
nent is present in the LCD element, and the two horizontal
shift register clocks drive the horizontal shift registers inside
the LCD panel so that the 1H transposed RGB signals are
applied to the LCD panel.
Because the LCD closes more as the difference in potential
between the VCOM (common polar voltage: fixed at DC) and
the R, G and B signals becomes greater, the display becomes
darker; if the difference in potential is smaller, the element
opens and the LCD become brighter. In addition, the bright-
ness and contrast settings for the LCD can be varied by means
of the serial data from the ASIC.

The low-voltage alternating current which is generated by the
oscillation control circuit is converted to a high-voltage alter-
nating current by the oscillation transformer.

1-5. Rectifier circuit
The high-voltage alternating current which is generated at
the secondary side of T5401 is rectified to produce a high-
voltage direct current and is accumulated at electrolytic ca-
pacitor C5412 on the main circuit board.

This circuit is used to maintain the voltage accumulated at
C5412 at a constance level.
After the charging voltage is divided and converted to a lower
voltage by R5417 and R5419, it is output to the SY1 circuit
board as the monitoring voltage VMONIT. When this VMONIT
voltage reaches a specified level at the SY1 circuit board, the
CHG signal is switched to Low and charging is interrupted.

The SY1 circuit board carries out overall control of camera operation by detecting the input from the keyboard and the condition
of the camera circuits. The 8-bit microprocessor reads the signals from each sensor element as input data and outputs this data
to the camera circuits (ASIC) or to the LCD display device as operation mode setting data. Fig. 4-1 shows the internal commu-
nication between the 8-bit microprocessor and ASIC.

4. Power Supply Control
The 8-bit microprocessor controls the power supply for the overall system.
The following is a description of how the power supply is turned on and off. When the battery is attached, a regulated 3.3 V
voltage is normally input to the 8-bit microprocessor (IC301) by IC303, so that clock counting and key scanning is carried out
even when the power switch is turned off, so that the camera can start up again. When the battery is removed, the 8-bit micro-
processor operates in sleep mode using the backup capacitor. At this time, the 8-bit microprocessor only carries out clock
counting, and waits in standby for the battery to be attached again. When a switch is operated, the 8-bit microprocessor supplies
power to the system as required.
The 8-bit microprocessor first sets both the P (A) ON signal at pin (70) and the P ON signal at pin (71) to low, and then turns on
the DC/DC converter. After this, High signals are output from pin (97) so that the ASIC is set to the active condition. If the LCD
monitor is on, the LCD ON signal at pin (95) set to Low, and the DC/DC converter for the LCD monitor is turned on.
