1.1 GENERAL DESCRIPTION
Ai7152S
Digital Signal Processor for Color CCD Cameras
The Ai7152S is a high performance CCD image signal processor for color video camera. It includes
MCU, timing generator, 2 channel 10bit digital to analog converter and all other functions for camera
system. Supports 250K/380K NTSC system CCD sensors and 290K/410K PAL system CCD sensors
with complementary color filter. It also provided programmable OSD function for convenient camera
setup. DNR function provide clean image even in low light condition.
