Camera Control; Audio And Vidceo; Flash - Sony DSC-S75 Training Manual

Camera Control

•
The camera is controlled by three processor ICs: CAMERA DSP IC301, MC CAM SH SP IC501 and the Front
Control I/O IC.
•
The CAMERA DSP converts the signals from the CCD into video signals for the LCD monitor and A/V jack.
•
The MC CAM SH DSP IC generates the characters for the LCD monitor and EVF, converts the video to data
that can be used by the USB protocol and the memory stick.
•
The Front Control IC on the FR-181 board processes the input commands from the camera switches dials
and sensors, and controls the flash pop-up solenoid
Audio and Video
The video drivers for the LCD panel, the color EVF (electronic view finder) and the NTSC output are on the PD-
155 board.
The audio driver for the speaker and the microphone preamp is on the FR-181 board.

Flash

The flash unit is recessed and pops up when flash is needed. It is replaced as a complete module. The flash
circuits are split up in two boards: the charging circuit and storage capacitors are located on the BT-006 board;
the rest of the circuits are located in the flash module. The normally hidden flash module is under spring tension
when recessed and is released by a solenoid when flash is needed.
