3. IC901 (V Driver) and IC911 (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.
IC901 is V driver. In addition the XV1-XV4 signals which are
output from IC102 are the vertical transfer clocks, and the
XSG signal which is output from IC102 is superimposed onto
XV1 and XV3 at IC901 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. A H driver
is inside IC911, and H1, H2 and RG clock are generated at
IC911.

4. IC911 (CDS, AGC Circuit and A/D Converter)

The video signal which is output from the CCD is input to Pin
(29) of IC911. 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 (37) of IC911. The video signal is
carried out A/D converter, and is output by 12-bit.

FIN4) which are output from the ASIC expansion port (IC107)
are used to drive by the motor driver (IC952). Detection of the
standard focusing positions is carried out by means of the
photointerruptor (PI) inside the lens block.

5-3. Zoom drive

The zoom stepping motor drive signals (ZIN1, ZIN2, ZIN3 and
ZIN4) which are output from the ASIC expansion port (IC107)

1-2. CA2 CIRCUIT DESCRIPTION

1. Circuit Description
1-1. Digital clamp

The optical black section of the CCD extracts averaged val­ues from the subsequent data to make the black level of the
CCD output data uniform for each line. The optical black sec­tion of the CCD averaged value for each line is taken as the
sum of the value for the previous line multiplied by the coeffi­cient 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 sig­nals 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 6­segment screen.

1-4. SDRAM controller

This circuit outputs address, RAS, CAS and AS data for con­trolling 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 be­tween individual input/output and PWM input/output.

1-6. TG/SG

Timing generated for 4 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 either Ye, Cy, Mg or 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 (smart media).
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

During monitoring, YUV conversion is carried out for the 12­bit 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 car­ried 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 12-bit
data which is output from the A/D conversion block of the
CCD is sent to the DRAM (DMA transfer), and after proces­sor, it is displayed on the LCD as a freeze-frame image.
During playback, the JPEG image data which has accumu­lated 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 con­verted into RGB signals by the LCD driver, and these RGB
signals and the control signal 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 registers inside the LCD panel so that the 1H
transposed RGB signals are applied to the LCD panel. Be­cause the LCD closes more as the difference in potential be­tween 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. CA3 CIRCUIT DESCRIPTION

1. Outline

This is the main CA3 power block, and is comprised of the
following blocks.
Switching controller (IC511)
Lens system 3.4 V power output (L5106, Q5104, D5105,
C5117)
Backlight power output (L5102, Q5101, C5113)
LCD system power output (Q5107, T5101)

2. Switching Controller (IC511)

This is the basic circuit which is necessary for controlling the
power supply for a PWM-type switching regulator, and is pro­vided with six built-in channels. They are CH5 (lens system

1-5. 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 switch­ing of the oscillation transformer.

1-3. Oscillation circuit

This circuit generates an AC voltage (pulse) in order to in­crease the UNREG power supply voltage when drops in cur­rent occur. This circuit generates a drive pulse with a frequency
of approximately 50-100 kHz. Because self-excited light omis­sion is used, the oscillation frequency changes according to
the drive conditions.

2. Light Emission Circuit

When RDY and TRIG signals are input from the ASIC expan­sion 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 gen­erated 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 ap­plied to the light emitting part, currnet flows to the light emit­ting element and light is emitted.

Beware of electric shocks.

1-4. Oscillation transformer

The low-voltage alternating current which is generated by the
oscillation control circuit is converted to a high-voltage alter­nating 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 high­voltage direct current and is accumulated at electrolytic ca­pacitor C5144 on the CA3 board.

1-6. Voltage monitoring circuit

This circuit is used to maintain the voltage accumulated at
C5144 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.

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 micro­processor operates in sleep mode using the backup capacitor. 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 (6) and the P ON signal at pin (5) to high, and then turns on the
DC/DC converter. After this, low signals are output from pins (62), (63) and (64) so that the ASIC is set to the active condition. If
the LCD monitor is on, the LCD ON signal at pin (7) 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.
