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
During EE, gamma conversion is carried out for the 12-bit
RGB data which is input from the A/D conversion block of the
CCD to the ASIC in order that the γ revised can be displayed
on the video. The YUV of 640 x 480 is then transferred to the
SDRAM.
The data which has accumulated in the SDRAM is converted
to digital YUV signal in conformity to ITUR-601 inside the ASIC
by SDRAM control circuit inside the ASIC, the data is sent to
the LCD driver IC and displayed the image to LCD panel.
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 accumu-
lated in the SD card is converted to YUV signals. In the same
way as for EE, the data is then sent to the SDRAM, con-
verted to digital YUV signal in conformity to ITUR-601 inside
the ASIC, the data is sent to the LCD driver IC and displayed
the image to LCD panel.
The LCD driver is converted digital YUV signals to RGB sig-
nals from ASIC, and these RGB signals and the control sig-
nal 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 regis-
ters inside the LCD panel so that the 1H/1V 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: AC drive) 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 bright-
ness and contrast settings for the LCD can be varied by means
of the serial data from the ASIC.

4. Lens drive block
4-1. Focus drive
The focusing motor is a stepping motor that is microprocessor
driven by IC951. When input the control signal (FCW, FOE
and FCLK) which are output from the ASIC port (IC101), the
focusing motor is driven microstep by IC951. Detection of the
standard focusing position is carried out by means of
photointerruptor sensor inside the lens block.
4-2. Zoom drive
The zoom motor is a stepping motor that is microprocessor
driven by IC951. When input the control signal (ZCW,
ZOOMOE, and ZCLK) which are output from the ASIC port
(IC101), the zoom motor is driven microstep by IC951. Detec-
tion of the standard zoom position is carried out by means of
photointerruptor sensor inside the lens block.
4-3. ND filter
IC951 turns the ND filter on and off when ND ON and ND OFF
signals are input to IC951 respectively.
4-4. Iris drive
The output from the Hall sensor inside the lens is amplified by
the Hall amplifier circuit in the lens drive block, and the differ-
ence in the target aperture values that are determined by the
output from that and by the exposure level output from the
ASIC is input to the servo amplifier circuit to automatically con-
trol the aperture opening so that it matches the target aperture
setting.
4-5. Shutter drive
The shutter is operated by applying a reverse voltage to the
aperture coil mentioned above. During normal operation, the
NAESW signal that is output from the ASIC is held at a High
level, but when the shutter operates, the NAESW signal be-
comes Low and after that the SHUTTER signal that is output
from the ASIC becomes High and the shutter operates.
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 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 IC104 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.

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. Power switch
When the CHG signal switches to Hi, Q5407 turns 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.
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, R5419 and R5420, it is output to the mi-
croprocessor as the monitoring voltage VMONIT. When this
VMONIT voltage reaches a specified level at the micropro-
cessor, 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 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 both the P (A) ON signal at pin (35) and the P ON signal at pin (34) to high, and then turns on
the DC/DC converter. After this, low signals are output from pins (50) and (28) 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.
