2.2.1.3 IC902 (H Driver) and IC904 (V Driver)

An H driver (IC902) and V driver (IC904) are necessary in order to generate the clocks (vertical transfer clock, horizontal transfer clock and electronic shutter clock) which driver the CCD. IC902 is an inverter IC which drives the horizontal

CCDs (H1 and H2). In addition the XV1-XV4 signals which are output from

IC102 are the vertical transfer clocks, and the XSG1 and XSG signal which is output from IC102 is superimposed onto XV1 and XV3 at IC904 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, and the RG signal which is output from IC102 is the reset gate clock.

2.2.1.4 IC905 (CDS, AGC Circuit, A/D Converter)

The video signal which is output from the CCD is input to Pins (26) and (27) of

IC905. There are S/H blocks inside IC905 generated from the XSHP and

XSHD pulse, and it is here that CDS (correlated double sampling) is carried out. After passing through the CDS circuit, the signal passes through the AGC amplifier. It is A/C converted internally into a 10-bit signal, and is then input to

IC102 of the CA2 circuit board. The gain of the AGC amplifier is controlled by the serial communication from IC102 of the CA2 circuit board.

Figure 2-6. IC902 Block Diagram





2.2.1.5 Transfer of Electric Charge by the Horizontal CCD

The transfer system for the horizontal CCD emplays a 2-phase drive method.

The electric charges sent to the final stage of the horizontal CCD are transferred to the floating diffusion, as shown in the figure below. RG is turned on by the timing in (1), and the floating diffusion is charged to the potential of

PD. The RG is turned off by the timing in (2). In this condition, the floating diffusion is floated at high impedance. The H1 potential becomes shallow by the timing in (3), and the electric charges now moves to the floating diffusion.

Here, the electric charges are converted into voltage at the rate of V=Q/C by the equivalent capacitance C of the floating diffusion. RG is then turned on again by the timing in (1) when the H1 potential becomes deep. Thus, the potential of the floating diffusion charges in proportion to the quality of transferred electric charge, and becomes CCD output after being received by the source follower. The equivalent circuit for the output circuit is shown in figure2-10.

2.2.2 CA2 Circuit Description

2.2.2.1 Outline of Operation

When the shutter opens, the reset signals (ASIC and CPU) and the serial signals (“take a picture” commands) from the 4-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 the JPEG method by JPEG IC and is then written to the memory. 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 memory to the SDRAM, and the image is then elongated so that it is displayed over the SDRAM display area.

2.2.2.3 LCD Block

During monitoring, YUV conversion is carried out for the 10-bit 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 10-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 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. 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

2.2.3.4 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, risen up to 5 V voltage is input to the IC304 by IC303, and regulated 3.2V voltage is normally input to the 8-bit microprocessor

(IC301) by IC304. That allows the clock to run to the camera to continue checking the power 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 super 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 4bit microprocessor supplies power to the system as required.

The 8-bit microprocessor first sets both the /P (A) ON signal at pin (71) and the

/P (A) ON signal at pin (70) to high, and then turns on the DC/DC converter.

After this, High signals are output from pins (97) and (88) so that the ASIC and the SPARC lite are set to the active condition. If the LCD monitor is on, the pin

(95) set to LCD ON signal, and the DC/DC converter for the LCD monitor is turned on. Once SPARC lite processing is completed, the ASIC and the

SPARC lite return to the reset condition, all DC/DC converters are turned off and the power supply to the whole system is halted.

2.2.4.2 Description of each block on the PW1 circuit

†

Switching Controller (IC501)

This is the basic circuit which is necessary for controlling the power supply for a PWM-type switching regulator, and is provided with four built-in channels, only CH1 (digital 3.3V), CH3 (5V system), CH2 (digital 3.4V) and

CH4 (analog and LCD system) are used. Feedback from 3.3V (D) (CH1),

3.4V (D) (CH2), 5.0V (D) (CH3) and +13V (A) or +12.4V (L) (CH4) power supply outputs are received, and the PWM duty is varied so that each one is maintained at the correct voltage setting level.

†

Short-circuit protection circuit

This is the basic circuit which is necessary for controlling the power supply for a PWM-type switching regulator, and is provided with one built-in channel, 5.5V (L) power supply outputs are received, and the PWM duty is varied so that each one is maintained at the correct voltage setting level.

„

Short-circuit protection circuit

If output is short-circuited for the length of time determined by the condenser which is connected to Pin (2) if IC502, all output is turned off. The control signal (P ON, P(A) ON and LCD ON) are controlled to restore output.

†

Digital 3.3V Power Output

(IC502) for PWM control to be carried out.



2.2.4.3 PW1 Strobe Circuit Description

Figure below shows the block diagram of Strobe circuit.

Figure 2-16. Strobe Circuit Block Diagram

†

Charging Circuit

When UNREG power supplied to the charge circuit and the CHG signal becomes High (3.3V), the charging circuit starts operating and the main electrolytic capacitor is charged with high-voltage direct current. However, when the CHG signal is Low (0V), the charging circuit does not operate.

„

Power switch:

When the CHG signal switches to Hi, Q5406 turns ON and the charging circuit starts operating.

„

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.

„

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.

„

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.

„

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 capacitor C5412 on the main circuit board.

„

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 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.

†

Light Emission Circuit

When RDY and TRIG signals are input from the ASIC expansion port, the stroboscope emits light.

†

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.

†

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.

†

Light emitting element

When the high-voltage pulse from the trigger circuit is applied to the light emitting part, current flows to the light emitting element and light is emitted.



W A R N I N G PW1 board has a danger of getting electric shock because of C5412. Hold the edges of this board and never touch the board surface when you handle this board. Discharge the charged energy of C5412 for safety before handling this board. (See Chatper 4 for more details)

TROUBLE SHOOTING

& + $ 3 7 ( 5 6


3.1 Overview

There is no function to indicate an error on this camera. Code indications, which sometimes are indicated on the LCD when the camera is in abnormal situation, are not reliable since they are still in the developing stage of ASIC, and it is difficult to find the specific malfunction. Also, sometimes several different malfunctions can be found from the same symptom. Therefore, check each checkpoints according to the procedure in this chapter and perform proper repair service.

W A R N I N G

„

Before disassembling the camera, make sure that batteries are removed or AC adapter is disconnected from the plug.

„

Electrolytic capacitor (C5412) mounted on the PW1 board is for flash emission. This capacitor is charged automatically every time the power is turned on.

Therefore, since there is a possibility to get electric shock during the service operation, release the electricity by using the cement resistance, if you need to touch the capacitor for repair service. (See Chapter 4 for more details)

3.2 Troubleshooting

Here shows the checking procedure for the malfunction unit or parts from the abnormal symptom.

3.2.1 Camera has no power

The LCD is not indicated or red LED keeps blinking and does not go to the stand-by state when the dial switch is turned on after installing the batteries or using the AC adapter. In this case, refer to Table 3-2 ∼ 3-4.

C A U T I O N

„

If 8-bit micro processor, which controls User I/F, located on the SY1 board becomes abnormal, the signal necessary to generate the various digital and analog power source will not be generated. As the result, the camera goes to “No Power” state.

„

Also, since this 8-bit micro processor performs serial communication with the main CPU on the CA2 board, if a trouble happens on the CA2 board, same symptom will appear.
