1-2. CP1 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. γ 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-segment
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. SIO
This is the interface for the 8-bit microprocessor.
2. PIO/PWM/SIO for LCD
8-bit parallel input and output makes it possible to switch be-
tween individual input/output and PWM input/output.
1-6. TG/SG
Timing generated for 5 million pixel CCD control.
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
8-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 12-bit data. The
AF, AE, AWB, shutter, and AGC value are computed from this
data, and three 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 ei-
ther R, G, and 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. After AWB
and γ processing are carried out, a matrix is generated and
aperture correction is carried out for the Y signal, and the
data is then compressed by JPEG and is then written to card
memory (SD card).
When the data is to be output to an external device, it is taken
data from the memory and output via the USART. When played
back on the LCD and monitor, data is transferred from memery
to the SDRAM, and the image is then elongated so that it is
displayed over the SDRAM display area.
3. LCD Block
The LCD display circuit is located on the CP1 board, and
consists of components such as a power circuit.
The signals from the ASIC are 8-bit digital signals, that is
input to the LCD directly. The 8-bit digital signals are con-
verted to RGB signals inside the LCD driver circuit . This LCD
has a 3-wire serial, and functions such as the brightness and
image quality are controlled.
Because the LCD closes more as the difference in potential
between the VCOM (common polar voltage: AC) 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 timing pulses for signals other than the video
signals are also input from the ASIC directory to the LCD.
4. Lens drive block
4-1. Focus drive
The focus stepping motor drive signals (FIN1, FIN2, FIN3, and
FIN4) which are output from ASIC (IC101) are used to drive
by the motor driver (IC951). Detection of the standard focus-
ing positions is carried out by means of the photointerruptor
(FOCUS PI) inside the lens block.
4-2. Zoom drive
The zoom stepping motor drive signals (ZIN1, ZIN2, ZIN3 and
ZIN4) which are output from ASIC (IC101) are used to drive by
the motor driver (IC951). Detection of the standard zoom posi-
tions is carried out by means of photointerruptor (ZOOM PI)
inside the lens block.
4-3. Iris drive
The iris motor drive signals (IIN1 and IIN2) which are output
from the ASIC (IC101) are converted into regular current drive
by the motor driver (IC951), and are then used to drive the iris
steps.
4-4. Shutter drive
The shutter motor drive signals (SIN1, SIN2) which are output
from the ASIC (IC101) are converted into regular current drive
by the motor drive (IC951), and the mecha shutter is opened
and closed.

V (CH6) and LED backlight constant current output (CH7)
power supply outputs are received, and the PWM duty is var-
ied so that each one is maintained at the correct voltage set-
ting level.
2-1. Short-circuit Protection

1-4. ST1 STROBE CIRCUIT DESCRIPTION
1. Charging Circuit
When UNREG power is supplied to the charge circuit and the
CHG signal from microprocessor 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. Charging switch
The CHG signal becomes High, Q5407 becomes ON and the
charging circuit starts operating.
1-2. Power supply filter
C5401 constitutes 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 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 as the monitoring
voltage VMONIT. When this VMONIT voltage reaches a speci-
fied level, the CHG signal is switched to Low and charging is
interrupted.
2. Light Emission Circuit
When FLCLT signals are input from the ASIC expansion port,
the stroboscope emits light.
2-1. Emission control circuit
When the FLCLT signal is input to Hi at the emission control
circuit, Q5409 switches on and preparation is made to the
light emitting. Moreover, when a FLCLT signal becomes Lo,
the stroboscope stops emitting light.
2-2. Trigger circuit
The Q5409 is turned ON by the FLCLT signal and light emis-
sion preparation is preformed. Simultaneously, high voltage
pulses of several kV are emitted from the trigger coil and ap-
plied to the light emitter.
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.

2. Setting of external port and communication
The SYA block 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. 5-1 shows the internal communication

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, IC500 is operating and
creating 4.7 V, a regulated 3.2 V voltage is normally input to the 8-bit microprocessor (IC301) by IC302, 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 power switch is off, the 8-bit microprocessor halts 4 MHz of the main clock, and operates 32.768 kHz of subclock.
When the battery is removed, the 8-bit microprocessor power switches the battery for memory backup by IC302, and operates at
low consumption. At this condition, the 8-bit microprocessor halts the main clock, and operates clock counting by sub clock.
Also, the battery for backup is charged 10 hours from it to be attached.
When the power switch is on, the 8-bit microprocessor starts processing. The 8-bit microprocessor first sets both the PON signal
at pin (19) and the PAON signal at pin (20) to High, and then turn on the power circuit. After PON signal is to High, sets external
port of ASIC after approximately 150 ms. According to setting of this external port, carry out setting of the operating frequency
and oscillation control in the ASIC. Also, it starts communication with ASIC, and confirms the system is operative.
When the through image is operating, set the PAON signal to High and then turn on the CCD. When the through image is playing,
set the PAON signal to Low and then turn off the CCD. When LCD panel turns on, set LCD ON signal at pin (21) and LCD ON2
signal at pin (14) to High, and then turn on the power. Set BL ON signal at pin (15) to High, and turn on the backlight power.
When the power switch is off, the lens will be stowed, and PON, PAON, LCDON and BL ON signals to Low and the power supply
to the whole system is halted. The 8-bit microprocessor halts oscillation of the main clock, and set operation mode of clock
oscillation.
