Ai3152
Digital Signal Processor for Color CCD Camera
General Description
The Ai3152 is the digital signal-processing chip for color video camera. It includes timing generator
and digital/analog output. Supports 250K / 380K NTSC system CCD sensors and 290K / 440K PAL
system CCD sensors with complementary color filter. It also provided line lock function.
Features
Support Ye, Cyan, Magenta, Green complementary color filter CCD sensors for
NTSC : Ai325CA(250K), Ai338CA(380K)
PAL : Ai329CA(290K), Ai344CA(440K)
Flexible Color Adjustment.
Digital Noise Reduction.
High performance AWB (5 set linear matrix).
IRIS coexists with AES and AGC.
Day or Night notice output.
Timing adjustment by 1 ns delay
White clip / Setup level / Sync level adjustment independent.
Build-in blemish compensation circuit to store the data in EEPROM,
the blemish pixel can up to 176 pixels.
Programmable pull-up / pull-down GPIO and DVIO pin.
Horizontal resolution up to 500 TVL
Video drive for IRIS lens is possible by simple drive circuit
even no CCD signal pin (CCDLEVEL or Mon_out) from AFE.
Hi-speed AE.
Support external EEPROM to store parameter.
Build-in auto white balance control.
Build-in auto exposure control.
Build-in backlight compensation.
Build-in 10bit digital to analog converter.
