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 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 12-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 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 in-

put to LCD panel directly by 6-bit digital signal, and are con-

verted 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 out-

put 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 (IC106),

the focus stepping motor is driven by the driver (IC951). De-

tection 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 out-

put from the ASIC (IC101), it is driven regular current by the

driver (IC951).

vided with five built-in channels, only CH1 (analog system

power output), CH2 (LCD 15 V power output), CH_M (digital

3.3 V system power output), CH_SD (digital 1.8 V system

power output), CH3 (LED back light power output) and CH_SU

(5 V system power output) are used. Feedback from 15.0 V

(CH_SD), LED backlight output (CH3) and 5 V (CH_SU) 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 setting inside

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), -7.6 V (A) and 3.45 V (A) are output. Feedback for

the 15.0 V (A) is provided to the switching controller (Pin (3)

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. 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 150-250 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

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 CHG-

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 expansion port,

the stroboscope emits light.

2-1. Emission control circuit

When the FLCLT signal is input to the emission control cir-

cuit, 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.

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 micro-

processor 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 (35) and the P ON signal at pin (34) to high, and then turns on

the DC/DC converter. After this, high signals are output from pins (12), (28), (49) and (50) so that the ASIC is set to the active

condition. If the LCD monitor is on, the LCD ON signal at pin (22) and the LCD ON 2 signal at pin (21) 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.

5. 16-bit A/D circuit (Audio)

This circuit converts the audio signals (analog signals) from the microphone to 16-bit digital signals.

6. 16-bit D/A circuit (Audio)

The audio signals which were converted to digial form by the 16-bit A/D circuit are temporarily to a sound buffer and then

recorded in the SSFDC card. During playback, the 16-bit D/A circuit converts these signals into analog audio signals.
