3. IC902 (H Driver) and IC904 (V Driver)
An H driver (IC902) and V driver (IC904) are necessary in
order to generate the clocks (vertical transfer clock, horizon-
tal 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 IC102 are the vertical transfer clocks, and the XSG1
and XSG signal which is output from 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 IC102
is used as the sweep pulse for the electronic shutter, and the
RG signal which is output from 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 volt-
age at pin (29) which is output from IC102 of the CA2 circuit
board and smoothed by the PWM.

Fig. 1-6. Horizontal Transfer of CCD Imager and Extraction of Signal Voltage
Fig. 1-7. Theory of Signal Extraction Operation
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
CCD output after being received by the source follower. The equivalent circuit for the output circuit is shown in Fig. 1-7.

6-1. Shutter drive
The shutter drive circuit (PCTRL) which is output from the ASIC
expansion port (IC109) is drived the shutter drive circuit, and
then shutter plunger opened and closed.
6-2. Iris and focus drive
The stepping motor drive signal (IN1, IN2 and ENA) for using
both iris and focus which is output from the ASIC expansion
port (IC109) is drived by motor driver (LB1838M). Detection of
the standard motoring positions is carried out by means of the
photointerruptor (PI) inside the lens block.
1-2. CA2 CIRCUIT DESCRIPTION
1. Circuit Description
1-1. Digital clamp
The optical black section of the CCD extracts averaged val-
ues from the subsequent data to make the black level of the
CCD output data uniform for each line. The optical black sec-
tion of the CCD averaged value for each line is taken as the
sum of the value for the previous line multiplied by the coeffi-
cient k and the value for the current line multiplied by the
coefficient 1-k.
1-2. Signal processor
1. correction circuit
This circuit performs (gamma) correction in order to maintain
a linear relationship between the light input to the camera
and the light output from the picture screen.
2. Color generation circuit
This circuit converts the CCD data into RGB signals.
3. Matrix circuit
This circuit generates the Y signals, R-Y signals and B-Y sig-
nals from the RGB signals.
4. Horizontal and vertical aperture circuit
This circuit is used gemerate the aperture signal.
1-3. AE/AWB and AF computing circuit
The AE/AWB carries out computation based on a 64-seg-
ment screen, and the AF carries out computations based on
a 6-segment screen.
1-4. SDRAM controller
This circuit outputs address, RAS, CAS and AS data for con-
trolling the SDRAM. It also refreshes the SDRAM.
1-5. Communication control
1. UART
The RS-232C can be sued for both synchronous and asyn-
chronous transmission.
2. SIO
This is the interface for the 4-bit microprocessor.
3. PIO/PWM/SIO for LCD
8-bit parallel input and output makes it possible to switch
between individual input/output and PWM input/output.
1-6. TG/SG
Timing generated for 1.3 million/1.09 million pixel CCD con-
trol.
1-7. Digital encorder
It generates chroma signal from color difference signal.
2. Outline of Operation
When the shutter opens, the reset signals (ASIC and CPU)
and the serial signals (“take a picture” commands) from the
4-bit microprocessor are input and operation starts. When
the TG/SG drives the CCD, picture data passes through the
A/D and CDS, and is then input to the ASIC as 10-bit data.
The AF, AE, AWB, shutter, and AGC value are computed from
this data, and three exposures are made to obtain the opti-
mum 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 Ye, Cy, Mg and Gr 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.
After AWB and processing are carried out, a matrix is gen-
erated and aperture correction is carried out, and the data is
then compressed by the JPEG method by (JPEG) and is then
written to card memory (smart media).
When the data is to be output to an external device, it is taken
data from the memory and output via the UART. When played
back on the LCD and monitor, data is transferred from memery
to the SDRAM, and is displayed over the SDRAM display
area.
3. LCD Block
During monitoring, YUV conversion is carried out for the 10-
bit CCD data which is input from the A/D conversion block to
the ASIC and is then transferred to the DRAM so that the
CCD data can be displayed on the LCD.
The data which has accumulated in the DRAM is passed
through the NTSC encoder , and after D/A conversion is car-
ried out to change the data into a 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 DRAM (DMA transfer), and after proces-
sor, it is displayed on the LCD as a freeze-frame image.
During playback, the JPEG image data which has accumu-
lated in the flash memory is converted to YUV signals, and
then in the same way as during monitoring, it is passed through
the NTSC endoder, and after D/A conversion is carried out to
change the data into a Y/C signal, the data is sent to the LCD
panel and displayed.
The two analog signal (Y/C signals) from the ASIC are con-
verted into RGB signals by the LCD driver, and these RGB
signals and control signal which output from 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. Be-
cause the LCD closes more as the difference in potential be-
tween the COM (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.
1-3. PW1 POWER CIRCUIT DESCRIPTION
1. Outline
This is the main power circuit, and is comprised of the follow-
ing blocks.
Switching controller (IC501)
Digital 5 V and analog system power output (Q5001, T5001)
Digital 3.5 V system power supply (Q5007)
Digital 2.6 V system power output (IC503)
LCD system power supply (Q5008, T5002)
Backlight power supply output (Q5011, T5003)
2. Switching Controller (IC501)
This is the basic circuit which is necessary for controlling the
power supply for a PWM-type switching regulator, and is pro-
vided with four built-in channels, only CH1 (digital 5 V, analog
system), CH3 (LCD system), CH2 (digital 3.5 V) and CH4
(backlight) are used. Feedback from 5 V (D) (CH1), 3.2 V (D)
(CH2) , 5.0 V (L) (CH3) and 7.7 V (L) (CH4) power supply
outputs are received, and the PWM duty is varied so that
each one is maintained at the correct voltage setting level.
2-1. Short-circuit protection circuit
If output is short-circuited for the length of time determined
by the condenser which is connected to Pin (17) of IC501, all
output is turned off. The control signal (P ON, P(A) ON and
LCD ON) are recontrolled to restore output.
3. Digital 5 V and Analog System Power Output
5 V (D) , 13 V (A), -7.0 V (A) and 5 V (A) are output. Feed-
back for the 5 V (D) is provided to the switching controller
(Pins (28) and (29) of IC501) so that PWM control can be
carried out.
4. Digital 3.5 V System Power Output
3.5 V (D) is output. Feedback is provided to the swiching con-
troller (Pin (25) and (26) of IC501) so that PWM control can
be carried out.
5. Digital 2.6 V Power Output
2.6 V (D) is output. 2.6 V (D) can be controled regular voltage
by series regulator IC (IC503).
6. LCD System Power Output
5 V (L) 1, 5 V (L) 2, 7.5 V (L), 13.5 V (L) and -15 V (L) are
output. Feedback for the 5 V (L) is provided to the switching
controller (Pin (11) and (12) of IC501) so that PWM control
can be carried out.
7. Backlight Power Supply output
7.7 V (L) is output. Feedback is sent to pins (7) and (8) of the
switching controller (IC501) for PWM control to be carried
out.
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 switch-
ing of the oscillation transformer.
1-3. Oscillation circuit
This circuit generates an AC voltage (pulse) in order to in-
crease the UNREG power supply voltage when drops in cur-
rent occur. This circuit generates a drive pulse with a frequency
of approximately 50-100 kHz. Because self-excited light omis-
sion is used, the oscillation frequency changes according to
the drive conditions.
1-4. Oscillation transformer
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.
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.
2. Light Emission Circuit
When RDY and TRIG signals are input from the ASIC expan-
sion 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 gen-
erated 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 ap-
plied to the light emitting part, currnet flows to the light emit-
ting element and light is emitted.
Beware of electric shocks.

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.
