RoHS
•This product does not contain any hazardous substances prohibited by the RoHS Directive.
WARNING
•You are requested to use RoHS compliant parts for maintenance or repair.
•You are requested to use lead-free solder.
(This product has been manufactured using lead-free solder. Be sure to follow the warning given on page 2 when
carrying out repair work.)

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.

Fig. 1-3. IC901 Block Diagram
3. IC905 (H Driver) and IC901 (V Driver)
An H driver (a part of IC905) and V driver (IC901) are neces-
sary in order to generate the clocks (vertical transfer clock,
horizontal transfer clock and electronic shutter clock) which
driver the CCD.
IC905 has clock generating which drives horizontal CCD and
its drives function. These clocks are output from pin (14), (15),
(18) and (19) of IC905. In addition the XV1-XV10 signals which
are output from IC101 are the vertical transfer clocks, and the
XSG1A, XSG1B, XSG2A, XSG2B, XSG2C, XSG3A and
XSG3B signals which are output is superimposed onto XV1,
XV3, XV5, XV7 and XV9 at IC901 in order to generate a ter-
nary pulse. In addition, the XSUB signal which is output from
IC101 is used as the sweep pulse for the electronic shutter,
and the RG signal which is output from pin (21) of IC905 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 (27) of IC905. There are S/H blocks inside IC905 gener-
ated 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 12-bit signal, and is then input to IC101 of the CP1 circuit
board. The gain of the AGC amplifier is controlled by pin (31)-
(33) serial signal which is output from IC101 of the CP1 board.

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 (k-1).
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 256-seg-
ment screen, and the AF carries out computations based on
a 11-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. It is pre-
pared for 16-bit parallel output.
1-6. TG/SG
Timing generated for 7 million pixel CCD control.
1-7. Digital encorder
It generates chroma signal from color difference signal.
1-8. JPEG encorder and decorder
It is compressed and elongated the data by JPEG system.
2. Outline of Operation
When the shutter opens, the serial signals (“take a picture”
commands) from the 8-bit microprocessor is input to ASIC
(IC101) 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 expo-
sures 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 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 the
JPEG method 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. When played
back on the LCD and monitor, data is transferred from memery
to the SDRAM, and the data elongated by JPEG decorder 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.

1-3. PWA POWER CIRCUIT DESCRIPTION
1. Outline
This is the main power circuit, and is comprised of the follow-
ing blocks.
Switching power control IC (IC501)
Analog 13 V (A) output system (L5003, Q5001)
Analog -7.5 V (A) output system (L5005, Q5005, IC502)
Analog 3.5 V (A) output system (IC503)
Digital 3.25 V (D) output system (L5001)
Digital 1.20 V (D) output system (L5002)
Backlight output system (L5006, Q5007)
Boost power (L5301)
2. Switching Power 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 eight built-in channels.
PWM/PFM switching step-up circuit …… 1 (ch_1)
PWM drive step-up/step-down circuit …… 1 (ch_2)
PWM drive step-up and step-down circuit …… total 4 (ch_3
and ch_5~ch_7)
PWM drive inverter circuit …… 1 (ch_4)
Variable regulator …… 1 (ch_8)
Only ch_1 (starting IC, lens drive, 8-bit microprocessor and
ch_3 source), ch_2 (digital 3.25 V), ch_3 (digital 1.20 V), ch_4
(analog -7.5 V), ch_5 (analog 13 V), ch_6 (not used), ch_7
(backlight) and ch_8 (not used) are used. Feedback from 3.8
V (ch_1), 3.25 V (ch_2), 1.20 V (ch_3), -7.5 V (ch_4) and 13.0
V (ch_5) power supply outputs are received, and the PWM
duty is varied so that each one is maintained at the correct
voltage setting level.
Feedback for the backlight power (ch_7) is provided so that
regular current can be controlled to be current (approximately
20 mA) that was setting.
PWM/PFM switching can be carried out for ch_1, so that PFM
operation is enabled when the DSC is stopped (when the
power is off) which provides greater efficiency at times of low
loads (only the 8-bit microprocessor is driven).
2-1. Damage Prevention Circuit
When a short-circuit is generated for a constant period of time,
the capacitor that is connected to pin (1) of IC501 turns all
output off. It is also equipped with an overheating protection
circuit, so that when the element temperature becomes higher
than a certain temperature, all output is turned off in the same
way as for a short-circuit. To reset output, remove the cause
of the problem and then resend a control signal.
3. ch_1 Output System
3.6 V is output. Feedback for the 3.8 V output is provided to
the switching controller (Pin (36) of IC501) so that PWM con-
trol can be carried out. Also, it is the source for 3.5 V (A).
While DSC is stopped, control switches to PFM control.
4. ch_2 Output System
3.25 V (D) is output. Feedback for the 3.25 V (D) output is
provided to the switching controller (Pin (45) of IC501) so that
PWM control can be carried out.
5. ch_3 Output System
1.20 V (D) is output. Feedback for the 1.20 V (D) output is
provided to the swiching controller (Pin (44) of IC501) so that
PWM control can be carried out.
6. ch_4 Output System
-7.5 V is output. Feedback for the inverter circuit output is
provided to the switching power controller (Pin (38) of IC501)
so that PWM control can be carried out. This output is high
precision by IC503, and get to -7.5 V.
7. ch_5 Output System
13.0 V (A) is output. Feedback for the 13.0 V (A) is provided
to the switching power controller (Pin (39) of IC501) so that
PWM control can be carried out.
8. ch_7 Output System
Regular current is being transmitted to LED for backlight. Step-
down in the voltage from the LED are feedback to the switch-
ing power controller (Pin (42) of IC501) so that PWM control
can be carried out.
The control signal (LCD PWM) from the 8-bit system can be
used to adjust the backlight illumination.

1-4. CP1 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. Charge switch
When the CHG signal switches to Hi, IC541 starts charging
operation.
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 200-300 kHz, and drive the oscillation trans-
former. When the SW 3.2 V signal is input, the peak current
during oscillation changes.
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. Charge monitoring circuit
The functions programmed in the IC541 monitor oscillations
and estimate the charging voltage. If the voltage exceeds the
rated value, charging automatically stops. Then, the
ZCHG_DONE signal is changed to Lo output and a "charging
stopped" signal is sent to the microcomputer.
2. Light Emission Circuit
When FLCLT signal is input from the ASIC, the stroboscope
emits light.
2-1. Emission control circuit
When the FLCLT signal is input to the emission control cir-
cuit, Q5402 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 Q5402 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. Internal Communication Bus
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
between the 8-bit microprocessor and ASIC.

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, IC501 is operating and
creating 3.8 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 operates 32.768 kHz of clock.
When the battery is removed, the 8-bit microprocessor power switches the lithum secondary battery for memory backup by
IC302, and operates at low consumption. At this condition, operates 32.768 kHz clock counting by 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 the PON signal at
pin (30) to High, and then turn on the power circuit. After PON signal is to High, sets external port of ASIC after approximately
100 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-PAON4 signals (ASIC) to High and then turn on the CCD. When the through
image is playing, set the PAON-PAON4 signals to Low and then turn off the CCD. When LCD panel turns on, set BL ON signal at
pin (41) to High, and turn on the backlight power.
When the power switch is off, the lens will be stowed, and PON, PAON-PAON4 and BLON signals to Low and the power supply
to the whole system is halted. The 8-bit microprocessor set operation mode of clock ocillation (32.768 kHz).

5. Backlight Energy Saving Control
This model is equipped with a control function for switching the appearance of the LCD in accordance with the intensity of
external light in order to save power. The luminance sensor Q1905 detects the intensity of external light, and the results are A/D
converted and compared with the threshold value inside the microprocessor (pin (50) of IC301) in order to switch the lightness or
darkness of the backlight.
Brighter external light -> Brighter backlight (estimated normal outdoor level)
Darker external light -> Darker backlight (estimated normal indoor level)
Furthermore, there are two threshold values for light -> dark and dark -> light, and stable switching is maintained because of the
hysteresis between the two.
Switching of the backlight luminance is carried out by changing the PWM duty from the microprocessor (pin (40) of IC301) so that
the backlight LED current detection signal is added together with the feedback signal from the backlight illumination circuit (pin
(42) of IC501) to vary the current value for the LED.
