CCD Pin Description 3. IC901, IC902 (V Driver) and IC911 (H Driver) 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. IC901 and IC902 are V driver. In addition the XV1-XV4 sig- nals which are output from IC102 are the vertical transfer clocks, and the XSG signal which is output from IC102 is su- perimposed onto XV2 and XV3 at IC901 and IC902 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 elec- tronic shutter. A H driver is inside IC911, and H1A, H1B, H2A, H2B and RG clock are generated at IC911. – 2 – VDD VOUT

This is the timing generation circuit which generates the clocks (vertical transfer clock and electronic shutter clock) which drive the CCD. – 4 –, 3. LCD Block During EE, gamma conversion is carried out for the 10-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 SVRAM. The data which has accumulated in the SDRAM is after D/A conversion is carried out by SDRAM control circuit inside the ASIC, makes 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 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 compact flash card is converted to RGB signals. In the same way as for EE, the data is then sent to the SDRAM, after which D/A conversion is carried out inside the ASIC, and then the data is sent to the LCD panel and displayed. The LCD driver is converted Y/C signals to RGB signals from ASIC, 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 compo- nent 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 bright- ness and contrast settings for the LCD can be varied by means of the serial data from the ASIC. – 5 –, 1-3. CA3 CIRCUIT DESCRIPTION 1. Outline 3.

Voltage monitoring circuit This circuit is used to maintain the voltage accumulated at C5144 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. – 8 –, 1-6. SY1 CIRCUIT DESCRIPTION 1.

Key Operation – 10 –, 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 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 both the P (A) ON signal at pin (6) and the P ON signal at pin (5) to high, and then turns on the DC/DC converter. After this, low signals are output from pins (62), (63) and (64) so that the ASIC is set to the active condition. If the LCD monitor is on, the LCD ON signal at pin (7) 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. ASIC, 8 bit LCD

REGISTRATION

USB storage data is important for when the camera is con- nected to a computer via a USB connection. If there are any errors in the USB storage data, or if it has not been saved, the USB specification conditions will not be sat- isfied, so always check and save the USB storage data. Preparation: POWER switch: ON Adjustment method: 1. Connect the camera to a computer. (Refer to 3-5. Con- necting the camera to the computer on the page 16.) 2. Double-click on the DscCalDi127. 3. Click on the Get button in the USB storage window and check the USB storage data. VID: SANYO PID: VPC-MZ1E or VPC-MZ1EX or VPC-MZ1 Serial: Rev. : 1.00 4. Check the “Serial” in the above USB storage data. If the displayed value is different from the serial number printed on the base of the camera, enter the number on the base of the camera. Then click the Set button. 5. Next, check VID, PID and Rev. entries in the USB storage data. If any of them are different from the values in 3. above, make the changes and then click the corresponding Set button.
