3. IC934, IC935 (V Driver) and IC931 (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.
IC934 and IC935 are V driver. In addition the XV1-XV6 sig­nals which are output from IC101 are the vertical transfer
clocks, and the XSG signal is superimposed at IC934 and
IC935 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 IC931,
and H1, H2 and RG clock are generated at IC931.

1-2. CP1 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 3 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 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 (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

LCD block is in the CP1 board, and it is constructed by VCOM
gerenated circuit etc. The video signal from the ASIC are in­put to LCD panel directly by 6-bit digital signal, and are con­verted into RGB signals by driver circuit in the LCD panel.
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 inpotential is smaller, the element opens and
the LCD becomes brighter. And also timing pulse except video
signal are input at LCD panel directly from ASIC.

4. Lens drive block

4-1. Iris drive

When the drive signals (AMIN_A and AMIN_-A) which are out­put from the ASIC (IC101), it is driven by the driver (IC951),
and are then used to drive the iris steps.

4-2. Focus drive

When the drive signals (FIN_A, FIN_-A, FIN_B and FIN_-B)
which are output from the ASIC expansion I/O port (IC105),
the focus stepping motor is driven by the driver (IC951). De­tection of the standard focusing positions is carried out by
means of the photointerruptor (FOCUS PI) inside the lens block.

4-3. Zoom drive

When the drive signals (ZIN_A, ZIN_-A, ZIN_B and ZIN_-B)
which are output from the ASIC (IC101), the zoom stepping
motor is driven by the driver (IC951). Detection of the standard
zoom positions is carried out by means of photointerruptor
(ZOOM PI) inside the lens block.

4-4. Shutter drive

When the drive signals (SMIN_A and SMIN_-A) which are out­put from the ASIC (IC101), it is driven regular current by the
driver (IC951).

1-3. PW1 POWER CIRCUIT DESCRIPTION

1. Outline

This is the main power circuit, and is comprised of the follow­ing blocks.
Switching power controller (IC501)
Analog system power output (Q5001, T5001)
Digital 1.8 V power output (Q5011, L5007)
Digital 3.3 V power output (Q5010, L5005)
LED backlight power output (Q5015, L5010)
5 V system power output (Q5018, L5017)

2. Switching Controller

This is the basic circuit which is necessary for controlling the
power supply for a PWM-type switching regulator, and is pro­vided with five built-in channels, only CH1 (analog system
power output), CH2 (digital 3.3 V system power output), CH3
(digital 1.8 V system power output), CH4 (LED back light power
output) and CH5 (5 V system power output) are used. Feed­back from 15.0 V (A) (CH1), 3.3 V (D) (CH2), 1.8 V (D) (CH3),
LED backlight output (CH4) and 5 V (CH5) power supply out­puts are received, and the PWM duty is varied so that each
one is maintained at the correct voltage setting level.

2-1. Short-circuit Protection

If output is short-circuited for the length of time determined
by the condenser which is connected to Pin (27) of IC501, all
output is turned off. The control signal (P ON) are recontrolled
to restore output.

3. Analog System Power Output

15.0 V (A) and -7.6 V (A) are output. Feedback for the 15.0 V
(A) is provided to the switching controller (Pin (23) of IC501)
so that PWM control can be carried out.

4. Digital 1.8 V Power Output

1.8 V (D) is output. Feedback for the 1.8 V (D) is provided to
the switching controller (Pins (15) of IC501) so that PWM con­trol can be carried out.

5. Digital 3.3 V Power Output

3.3 V (D) is output. Feedback for the 3.3 V (D) is provided to
the swiching controller (Pin (42) of IC501) so that PWM con­trol can be carried out.

6. LED Backlight Power Output

A constant current flows to the backlight LEDs. Feedback for
the voltage of R5057 is provided to the power controller (Pin
(18) of IC501) so that PWM control can be carried out.

7. 5 V System Power Output

5 V is output. Feedback for the 5 V is provided to the swiching
controller (Pin (39) of IC501) so that PWM control can be
carried out.

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 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 C5512.

1-6. Voltage monitoring circuit

This circuit is used to maintain the voltage accumulated at
C5512 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 mi­croprocessor as the monitoring voltage VMONIT. When this
VMONIT voltage reaches a specified level at the micropro­cessor, the CHG signal is switched to Low and charging is
interrupted.

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, ASIC and SPARC lite circuits.

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 lithium secondary 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 (6) and the P ON signal at pin (5) to high, and then turns on the
DC/DC converter. After this, high signals are output from pins (60), (61), (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 (21) and the LCD ON 2 signal at pin (53) 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.
