WARNING
Do not use solder containing lead.
This product has been manufactured using lead-free solder in
order to help preserve the environment.
Because of this, be sure to use lead-free solder when carrying
out repair work, and never use solder containing lead.
Lead-free solder has a melting point that is 30 - 40°C (86 -
104°F) higher than solder containing lead, and moreover it does
not contain lead which attaches easily to other metals. As a
result, it does not melt as easily as solder containing lead, and
soldering will be more difficult even if the temperature of the
soldering iron is increased.
The extra difficulty in soldering means that soldering time will
increase and damage to the components or the circuit board
may easily occur.
Because of this, you should use a soldering iron and solder
that satisfy the following conditions when carrying out repair
work.
Soldering iron
Use a soldering iron which is 70 W or equivalent, and which
lets you adjust the tip temperature up to 450°C (842°F). It
should also have as good temperature recovery characteris-
tics as possible.
Set the temperature to 350°C (662°F) or less for chip compo-
nents, to 380°C (716°F) for lead wires and similar, and to 420°C
(788°F) when installing and removing shield plates.
The tip of the soldering iron should have a C-cut shape or a
driver shape so that it can contact the circuit board as flat or in
a line as much as possible.
Solder
Use solder with the metal content and composition ratio by
weight given in the table below. Do not use solders which do
not meet these conditions.
Lead-free solder is available for purchase as a service tool.
Use the following part number when ordering:
Part name: Lead-free solder with resin (0.5 mm dia., 500 g)
Part number: VJ8-0270
Metal content
Tin (Sn) Silver (Ag)
Copper (Cu)
Composition
ratio by weight
96.5 %
3.0 %
0.5 %
Note:
If replacing existing solder containing lead with lead-free sol-
der in the soldered parts of products that have been manufac-
tured up until now, remove all of the existing solder at those
parts before applying the lead-free solder.

3. IC902, IC903 (V Driver) and IC905 (H driver)
An H driver and V driver are necessary in order to generate
the clocks (vertical transfer clock, horizontal transfer clock
and electronic shutter clock) which driver the CCD.
IC902 and IC903 are V driver. In addition the XV1-XV6 sig-
nals which are output from IC101 are the vertical transfer
clocks, and the XSG signal is superimposed at IC902 and
IC903 in order to generate a ternary pulse. In addition, the
XSUB signal which is output from IC101 is used as the sweep
pulse for the electronic shutter. A H driver is inside IC905,
and H1, H2 and RG clock are generated at IC905.
4. IC905 (CDS, AGC Circuit and A/D Converter)
The video signal which is output from the CCD is input to Pin
(27) of IC905. There are inside the sampling hold block, AGC
block and A/D converter block.
The setting of sampling phase and AGC amplifier is carried
out by serial data at Pin (32). The video signal is carried out
A/D converter, and is output by 12-bit.

1-2. CP1 and VF1 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 4 million pixel horizontal addtion 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 10-bit
data. The AF, AE, AWB, shutter, and AGC value are com-
puted 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 either R, G, and B primary color data to pro-
duce 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 USB I/F. 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 6-bit digital signals, that is
input to the LCD directly. The 6-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 motor is a stepping motor which is microstep-driven
by IC951. The 4 MHz clock signal (OSCIN) of the control sig-
nals (3-wire serial control (SDATA, SCLK, SENAB), VD) and
SUB CPU that are output from the ASIC (IC101) port is input
to IC951 so that IC951 can microstep control the focus motor.
Detection of the standard focusing motor position is carried
out by means of photointerruptor sensor inside the lens.
4-2. Zoom drive
The zoom motor is a stepping motor which is microstep-driven
by IC951. The 4 MHz clock signal (OSCIN) of the control sig-
nals (3-wire serial control (SDATA, SCLK, SENAB), VD) and
SUB CPU that are output from the ASIC (IC101) port is input
to IC951 so that IC951 can microstep control the zoom motor.
Detection of the standard zoom motor position is carried out
by means of photointerruptor sensor inside the lens.
4-3. ND filter
ND filter control is carried out by the control signals (ND ON
and ND OFF) that are output from the ASIC (IC101) port and
input to IC951 so that IC951 can drive the ND filter.
The 4 MHz clock signals (OSCIN) of the 3-wire serial control
signals (SDATA, SCLK, SENAB) and SUB CPU allow IC951 to
operate.
4-4. Iris drive
The drive method is a galvanometer type without braking coil.
The aperture opening amout is controlled as follows: the out-
put from the Hall sensor inside the lens is amplified by the Hall
amplifier circuit inside the IC971 lens drive IC, and the differ-
ence between the current and target aperture determined by
the resulting output and the exposure amout output from the
ASIC (IC101) is input to the servo amplifier circuit (IC971) to
keep the aperture automatically controlled to the target aper-
ture. The lens aperture control signal is output from IC971 and
is input to lens drive IN6B of IC951. IC951 functions as the
driver for driving the lens.
The 4 MHz clock signals (OSCIN) of the 3-wire serial control
signals (SDATA, SCLK, SENAB) and SUB CPU allow IC951 to
operate.
4-5. Shutter drive
Reverse voltage is applied to the above aperture coil to oper-
ate the shutter. With normal operation, the OC_EN and
OC_CONT signals that are output from the ASIC (IC101) are
maintained at a low level and when the shutter operates, the
OC_EN and OC_CONT signals switch to high, and after that
the SHUTTER + signal that is output from the ASIC (IC101)
becomes high and the shutter operates.
It is input to lens drive IN6B of IC951 with low level. IC951
functions as the driver for driving the lens.
The 4 MHz clock signals (OSCIN) of the 3-wire serial control
signals (SDATA, SCLK, SENAB) and SUB CPU allow IC951 to
operate.
5. Video clip recording and playback
5-1. Recording
The signals from the camera block are input to the ASIC where
they are processed, and the image data that is stored in the
SDRAM of IC103 is input to the IC102 MPEG4 CODEC LSI.
The CODEC LSI converts this data to encoded MPEG4 data,
after which it is returned to the ASIC as streaming data, and
the data is then written in sequence onto the SD card. At this
time, the audio signals that are input to the built-in microphone
are converted into digital data by the audio CODEC IC of IC183,
and they are then input via the ASIC to IC102 (MPEG4
CODEC). The audio data is then encoded (AAC) by IC102,
and then it is returned to the ASIC as streaming data and is
then written in sequence onto the SD card together with the
image signals described above.
5-2. Playback
The data is read from the SD card and input to IC102 as stream-
ing data. The encoded data is decoded into image data by
IC102 and then returned to the ASIC where it is displayed by
the LCD or on a TV monitor. At this time, the audio data is also
decoded by IC102, and it passes through the ASIC and is in-
put to IC183 as digital data. D/A conversion is carried out at
IC183, and the sound is then output to the speaker or to the
LINE OUT terminal.
6. Audio CODEC circuit (IC183)
The audio signals from the microphone are converted into 16-
bit digital data. AD conversion is carried out at a maximum
sampling frequency of 48 kHz.
During audio playback, the 16-bit digital data is converted into
analog signals and these drive the speaker or line out system.
DA conversion is carried out at a maximum sampling frequency
of 48 kHz.

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 100-200 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.
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 R5405 and R5406, it is output as the monitoring
voltage VMONIT. When VMONIT voltage reaches a specified
level, the CHG signal is switched to Low and charging is in-
terrupted.
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.

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 3.2 V
voltage is normally input to the 8-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 8-bit micro-
processor operates in sleep mode using the backup lithum battery. 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 the P ON signal at pin (40) to high, and then turns on the DC/DC converter. After this, low
signals are output from pin (17) so that the ASIC is set to the reset condition. After this these pins set to high, and set to active
condition. If the LCD monitor is on, the LCD ON 1 signal at pin (22) set to high, and the DC/DC converter for the LCD monitor is
turned on. Once it is completed, the ASIC returns to the reset condition, all DC/DC converters are turned off and the power
supply to the whole system is halted.
