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. 1-6.
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

2. Internal Communication Bus
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 4-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 4-bit microprocessor, ASIC and SPARC lite circuits.

4. Power Supply Control
The 4-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 3.2 V
voltage is normally input to the 4-bit microprocessor (IC301) by IC302, 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 4-bit micro-
processor operates in sleep mode using the backup capacitor (C3050). At this time, the 4-bit microprocessor only carries out
clock counting, and waits in standby for the battery to be attached again. When a switch is operated, the 4-bit microprocessor
supplies power to the system as required.
The 4-bit microprocessor first sets both the P (A) ON signal at pin (3) and the P ON signal at pin (4) to low, and then turns on the
DC/DC converter. After this, High signals are output from pins (7) and (8) so that the ASIC and the SPARC lite are set to the
active condition. If the LCD monitor is on, the LCD ON 1 signal at pin (12) and the LCD ON 2 signal at pin (2) set to Low, and the
DC/DC converter for the LCD monitor is turned on. Once SPARC lite processing is completed, the ASIC and the SPARC lite
return to the reset condition, all DC/DC converters are turned off and the power supply to the whole system is halted.
