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.

2. Switching Controller

This is the basic circuit which is necessary for controlling the

power supply for a PWM-type switching regulator, and is pro-

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

power output), CH_M (digital 3.3 V system power output),

CH_SD (digital 1.8 V system power output), CH3 (LCD and

LED back light power output) and CH_SU (5 V system power

output) are used. Feedback from 15.0 V (A) (CH1), 3.3 V (D)

(CH_M), 1.8 V (D) (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) and -7.6 V (A) are output. Feedback for the 15.0 V

(A) is provided to the switching controller (Pin (3) 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 (9) of IC501) so that PWM con-

trol can be carried out.

5. Digital 3.3 V 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. 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.

2. Internal Communication Bus

The SY1 circuit 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 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.
