3. IC903 (H Driver) and IC902 (V Driver)

An H driver (IC903) and V driver (IC902) 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 VREG 0~7, VXREG2 and VXREG3 signals which are output from IC102 are the vertical transfer clocks. The clock is drived until peak value which necessary CCD at IC902.

4. IC901 (CDS, AGC Circuit and A/D Converter)

The video signal which is output from the CCD is input to Pins (26) and (27) of IC901. There are S/H blocks inside IC905 generated from the XSHP and XSHD pulses, 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.

5. Transfer of Electric Charge by the Horizontal CCD

The transfer system for the horizontal CCD emplays a 4-phase drive method. The electric charges sent to the final stage of the horizontal CCD are transferred to the floating diffusion (FD), as shown in Fig. 1-6. PR is turned on by the timing in (1), and the floating diffusion is charged to the potential of RD. The PR is turned off by the timing in (2). In this condition, the floating diffusion is floated at high impedance. The H2 potential becomes shallow by the timing in (3), and the electric charge now moves to the floating diffusion. Here, the electric charges are converted into voltages at the rate of V = Q/C by the equivalent capacitance C of the floating diffusion. PR is then turned on again by the timing in (1) when the H2 potential becomes deep. Thus, the potential of the floating diffusion changes in proportion to the quantity 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 Fig. 1-7.

1-2. CA-B CIRCUIT DESCRIPTION

1. Circuit description 1-1. PTG

This is program timing generator. Generates the timing signal that is needed in order to drive the FT-CCD sensor.

1-2. FCP

The FCP receives the output data from the FT-CCD sensor via the PTG, and then carries out various processing operations on the data (such as gamma correction and white banance).

1-3. ITP

The ITP is a pixel conversion processor. It carries out various processing operations (such as contour emphasis and chroma) on the image data that is input from the FCP or from memory, and then stores the processed data in memory.

1-4. CPU

This is 32 bit RISC CPU.

1-5. Memory controller

This is controlled SDRAM, flash ROM and CF card etc.

1-6. Video player

Outputs the RGB signals that are needed to control the graphic overlay function and to drive the LCD.

1-7. GPIO

This is a multipurpose I/O. (It can be used as an input/output port.)

1-8. COM port

This is communication block. Supports USB communication.

2. Outline of Operation

When the shutter opens, detect the 8-bit microprocessor and transmit to record operation starts. When the PTG drives the FT-CCD, picture data passes through the A/D and is then input to the ASIC as 10-bit data. This data then sends FCP, after which it is carried out various processing operations on the data (such as gamma correction and white balance). The data is then sent to the ITP where processing such as contour emphasis and chroma are carried out, after which it is temporarily stored in the SDRAM. In case of still picture the data is then compressed by the JPEG method and in case of picture it is compressed by MJPEG method and is written to compact flash card.

3. LCD Block

RGB signals corresponding to the LCD driver are output from the ASIC (video player). The LCD driver converts the RGB signals that are output from the ASIC to a signal level that is appropriate for the LCD monitor. 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 VCOM (common polar voltage: fixed at DC) 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 brightness and contrast settings for the LCD can be varied by means of the serial data from the ASIC.

1-9. Serial communication

This is the interface for the 8-bit microprocessor.

1-10. LCD driver

The RGB output signals that are output from the ASIC are converted to a signal level that is appropriate for the LCD monitor.

1-11. LCD monitor

This is the image display device which displays the image signals supplied from the LCD driver.

1-3. CP1 POWER CIRCUIT DESCRIPTION

1. Outline

This is the main power circuit, and is comprised of the following blocks. Switching controller (IC501) Digital 5 V and analog system power output (T5001, Q5001) Digital 2.5 V system power supply (Q5007) Digital 3.4 V system power supply (Q5018) LCD system power supply (Q5008, T5002) Backlight power supply output (Q5013) Inverter output (T5003, Q5017)

2. 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 five built-in channels, only CH2 (digital 5 V, analog system), CH4 (LCD system), CH3 (digital 2.5 V), CH1 (digital

3.4 V) and CH5 (backlight system) are used. Feedback from 5 V (D) (CH2), 2.5 V (D) (CH3) , 12.4 V (L) (CH4), 3.4 V (D) (CH1) and 7 V (L) (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 circuit

If output is short-circuited for the length of time determined by the condenser which is connected to Pin (29) of IC501, all output is turned off. The control signal (P ON) are recontrolled to restore output.

3. Digital 3.4 V Power Output

3.4 V (D) is output. Feedback is sent to pin (41) of the switching controller (IC501) for PWM control to be carried out.

4. Digital 5 V and Analog System Power Output

5.1 V (D) , 26.4 V (A), 20 V (A), 13 V (A) and 5.1 V (A) are output. Feedback for the 5.1 V (D) is provided to the switching controller (Pins (35) of IC501) so that PWM control can be carried out.

5. Digital 2.5 V System Power Output

2.5 V (D) is output. Feedback is provided to the swiching controller (Pin (23) of IC501) so that PWM control can be carried out.

6. LCD System Power Output

12.4 V (L) is output. Feedback for the 12.4 V (L) is provided to the switching controller (Pins (22) of IC501) so that PWM control can be carried out.

7. Backlight Power Supply output

7.0 V (L) is output. Feedback is sent to pin (17) of the switching controller (IC501) for PWM control to be carried out.

8. Inverter Output

The backlight uses a flat picture tube. When INV CLK is input, Q5017 carries out switching operations, so that T5003 is energized and a high-voltage pulse is generated between pins (3) and (4) of T5003. This high-voltage pulse is applied to the backlight to make it illuminate.

1-4. CP1 STROBO CIRCUIT DESCRIPTION

1. Charging Circuit

When UNREG power is supplied to the charge circuit and the CHG signal 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, Q5406 turns ON and the charging circuit starts operating.

1-2. Power supply filter

L5401 and C5405 constitute 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, 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 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 to the SY-A block as the monitoring voltage VMONIT. When this VMONIT voltage reaches a specified level at the SY-A block, the CHG signal is switched to Low and charging is interrupted.

2. Internal Communication Bus

The SY-A 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. 4-1 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 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 8-bit microprocessor supplies power to the system as required. The 8-bit microprocessor first sets the P ON signal at pin (34) to high, and then turns on the DC/DC converter for the digital system. After this, it sets RESET B signal at pin (33) to high so that the ASIC is set to the active condition. After this, in case of driving the CCD, it sets the P (A) ON signal at pin (176) of the ASIC to high, and then turns on the DC/DC converter for the analog system. If the LCD monitor is on, the LCD ON signal at pin (175) of the ASIC 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.
