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 5 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 ei-

ther 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 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 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

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.

4. Lens drive block

4-1. Focus drive

The focus stepping motor drive signals (FIN1, FIN2, FIN3, and

FIN4) which are output from ASIC (IC101) are used to drive

by the motor driver (IC951). Detection of the standard focus-

ing positions is carried out by means of the photointerruptor

(FOCUS PI) inside the lens block.

4-2. Zoom drive

The zoom stepping motor drive signals (ZIN1, ZIN2, ZIN3 and

ZIN4) which are output from ASIC (IC101) are used to drive by

the motor driver (IC951). Detection of the standard zoom posi-

tions is carried out by means of photointerruptor (ZOOM PI)

inside the lens block.

4-3. Iris drive

The iris motor drive signals (IIN1 and IIN2) which are output

from the ASIC (IC101) are converted into regular current drive

by the motor driver (IC951), and are then used to drive the iris

steps.

4-4. Shutter drive

The shutter motor drive signals (SIN1, SIN2) which are output

from the ASIC (IC101) are converted into regular current drive

by the motor drive (IC951), and the mecha shutter is opened

and closed.

vided with seven built-in channels, only CH1 (input voltage

5.8 V to CH2, CH3 and CH4), CH2 (digital 3.25 V system

power output), CH3 (digital 1.7 V system power output), CH4

(analog 3.45 V system power output), CH5 (analog system

power output) CH6 (LCD system power output) and CH7 (LCD

backlight system power output) are used. Feedback from in-

put voltage 5.8 V to CH2, CH3 and CH4 (CH1), VDD3 (CH2),

VDD1.8 (CH3), +3.45 V (A) (CH4), +12 V (A) (CH5), LCD 12

V (CH6) and LED backlight constant current output (CH7)

power supply outputs are received, and the PWM duty is var-

ied so that each one is maintained at the correct voltage set-

ting 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 (9) of IC501, all

output is turned off. The control signal (P ON) are recontrolled

to restore output.

3. Digital 3.25 V System Power Output

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. Charging switch

The CHG signal becomes High, Q5407 becomes 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 on the main circuit board.

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 and R5419, it is output as the monitoring

voltage VMONIT. When this VMONIT voltage reaches a speci-

fied level, the CHG signal is switched to Low and charging is

interrupted.

2. Light Emission Circuit

When FLCLT signals are input from the ASIC expansion port,

the stroboscope emits light.

2-1. Emission control circuit

When the FLCLT signal is input to Hi at the emission control

circuit, 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.

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, IC500 is operating and

creating 4.7 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 halts 4 MHz of the main clock, and operates 32.768 kHz of subclock.

When the battery is removed, the 8-bit microprocessor power switches the battery for memory backup by IC302, and operates at

low consumption. At this condition, the 8-bit microprocessor halts the main clock, and operates clock counting by sub 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 both the PON signal

at pin (19) and the PAON signal at pin (20) to High, and then turn on the power circuit. After PON signal is to High, sets external

port of ASIC after approximately 150 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 signal to High and then turn on the CCD. When the through image is playing,

set the PAON signal to Low and then turn off the CCD. When LCD panel turns on, set LCD ON signal at pin (21) and LCD ON2

signal at pin (14) to High, and then turn on the power. Set BL ON signal at pin (15) to High, and turn on the backlight power.

When the power switch is off, the lens will be stowed, and PON, PAON, LCDON and BL ON signals to Low and the power supply

to the whole system is halted. The 8-bit microprocessor halts oscillation of the main clock, and set operation mode of clock

oscillation.
