An H driver (IC902) and V driver (IC904) are necessary in
order to generate the clocks (vertical transfer clock, horizontal transfer clock and electronic shutter clock) which driver
the CCD.
IC902 is an inverter IC which drives the horizontal CCDs (H1
and H2). In addition the XV1-XV4 signals which are output
from Pins (166), (167), (169) and (171) of IC102 are the vertical transfer clocks, and the XSG1 and XSG2 signals which
is output from Pins (168) and (170) of IC102 is superimposed
onto XV1 and XV3 at IC904 in order to generate a ternary
pulse. In addition, the XSUB signal which is output from Pin
(165) of IC102 is used as the sweep pulse for the electronic
shutter, and the RG signal which is output from Pin (159) of
IC102 is the reset gate clock.

4. IC905 (CDS, AGC Circuit and A/D converter)
The video signal which is output from the CCD is input to
Pins (26) and (27) of IC905. There are S/H blocks inside IC905
generated from the XSHP and XSHD pulses, and it is here
that CDS (correlated double sampling) is carried out.
After passing through the CDS circuit, the signal passes
through the AGC amplifier. It is A/C converted internally into
a 10-bit signal, and is then input to IC102 of the CA2 circuit
board. The gain of the AGC amplifier is controlled by the voltage at pin (29) which is output from IC102 of the CA2 circuit
board and smoothed by the PWM.

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
CCD output after being received by the source follower. The equivalent circuit for the output circuit is shown in Fig. 1-6.

Fig. 1-5. Horizontal Transfer of CCD Imager and Extraction of Signal Voltage
This circuit uses the function of a 64-Mbit SDRAMs to convert the non-interlaced signal which is output from the CCD
into an interlaced signal for the video monitor.
1-2. Camera signal processor
This comprises circuits such as the digial clamp circuit, white
balance circuit, γcircuit, color signal generation circuit, matrix circuit and horizontal aperture circuit.
1. Digital clamp circuit
The optical black section of the CCD extracts 16-pixel averaged values from the subsequent data to make the black level
of the CCD output data uniform for each line. The 16-pixel
averaged value for each line is taken as the sum of the value
for the previous line multiplied by the coefficient k and the
value for the current line multiplied by the coefficient 1-k.
2. White balance circuit
This circuit controls the white balance by using the A WB judgement value computed by the CPU to control the gain for each
R, G and B pixel based on the CCD data which has been
read.
3. γ circuit
This circuit performs (gamma) correction in order to maintain
a linear relat ionship b etween the light i nput to the camer a
and the light output from the picture screen.
4. Color generation circuit
This circuit converts the CCD da ta int o RGB signal s.
5. Matrix circuit

the microphone to 8-bit digital signals.
1-8. 8-bit A/D circuit (Audio)
The audio signals which were converted to digial form by the
8-bit A/D circuit are temporarily to a sound buffer and then
recorded in the SSFDC card. During playback, the 8-bit D/A
circuit converts these signals into analog audio signals.
1-9. Sound buffer
Audio memory
1-10. LCD driver
The Y/C signals which are input to the LCD driver are converted to RGB signals, and the timing signal which is necessary for LCD monitor display and the RGB signals are then
supplied to the LCD monitor.
1-11. LCD monitor
This is the image display device which displays the image
signals supplied from the LCD driver.
1-12. UART
This circuit is used for transmitting serial data to a PC. The
interface is RS-232C-compatible.
1-13. SSFDC control
This reads data from the SSFDC card and stores it in SDRAM,
and writes out the image data stored in SDRAM. In addition,
error correction is carried out when the data is read.
1-14. MJPEG compression
Still and continuous frame data is converted to JPEG format,
and movie images are compressed and expanded in MJPEG
format.
6. Horizontal aperture circuit
This circuit is used generate the aperture signal.
1-3. SDRAM controller
This circuit outputs address, RAS, CAS and AS data for controlling the SDRAM. It also refr eshes the S DRA M.
1-4. PIO
The expansion parallel port can be used for functions such
as stroboscope control and LCD driver control.
1-5. SIO (Serial control)
This is the interface for the 8-bit mic roprocessor.
1-6. TG, SG block
This is the timing generation circuit which generates the clocks
(vertical transfer clock and electronic shutter clock) which drive
the CCD.
2. Outline of Operation
When the shutter opens, the reset signals, TEST0, TEST1
and the serial signals (“take a picture” commands) from the
8-bit microprocessor are input and record operation starts.
When the TG drives the CCD, picture data passes through
the A/D and is then input to the ASIC as 10-bit data. This data
then passes through the DCLP, AWB, shutter and γcircuit,
after which it is input to the SDRAM. The AWB, shutter, γ,
and AGC value are computed from this data, and two exposures are made to obtain the optimum picture. The data which
has already been stored in the SDRAM is read by the CPU
and color generation is carried out. Each pixel is interpolated
from the surrounding data as being either R, G or B primary
color data to produce R, G and B data. At this time, correction
of the lens distortion which is a characteristic of wide-angle
lenses is carried out. Aperture correction is carried out, and
in case of still picture the data is then compressed by the
JPEG method and in case of picture it is compressed by
MJPEG method and is written to SSFDC card. When the data
is to be output to an external device, it is read JPEG picture
data from the SSFCD card and output to PC via the UART.

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 γrevised 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 accumulated 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 component 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 brightness and contrast settings for the LCD can be varied by means
of the serial data from the ASIC.

1-4. PW1 STROBE CIRCUIT DESCRIPTION
1. Charging Circuit
When UNREG power is supplied to the charge circuit and the
CHG signal becomes High (3.3 V), the charging circuit starts
operating and the main electorolytic capacitor is charged with
high-voltage direct current.
However, when the CHG signal is Low (0 V), the charging
circuit does not operate.
1-1. Power switch
When the CHG signal switches to Hi, Q5406 turns ON and
the charging circuit starts operating.
1-2. Power supply filter
L5401 and C5401 constitute the power supply filter. They
smooth out ripples in the current which accompany the switching of the oscillation transformer.
1-3. Oscillation circuit
This circuit generates an AC voltage (pulse) in order to increase the UNREG power supply voltage when drops in current occur. This circuit generates a drive pulse with a frequency
of approximately 50-100 kHz. Because self-excited light omission is used, the oscillation frequency changes according to
the drive conditions.
2. Light Emission Circuit
When RDY and TRIG signals are input from the ASIC expansion port, the stroboscope emits light.
2-1. Emission control circuit
When the RDY signal is input to the emission control circuit,
Q5409 switches on and preparation is made to let current
flow to the light emitting element. Moreover, when a STOP
signal is input, the stroboscope stops emitting light.
2-2. Trigger circuit
When a TRIG signal is input to the trigger circuit, D5405
switches on, a high-voltage pulse of several kilovolts is generated inside the trigger circuit, and this pulse is then applied
to the light emitting part.
2-3. Light emitting element
When the high-voltage pulse form the trigger circuit is applied to the light emitting part, currnet flows to the light emitting element and light is emitted.
※ Beware of electric shocks.
1-4. Oscillation transformer
The low-voltage alternating current which is generated by the
oscillation control circuit is converted to a high-voltage alternating 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 highvoltage direct current and is accumulated at electrolytic capacitor C5412 on the main circuit board.
1-6. Voltage monitoring circuit
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.

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 microprocessor 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.
