ASX340AT

ASX340AT 1/4‐inch Color CMOS NTSC/PAL Digital Image SOC with Overlay Processor General Description The ON Semiconductor ASX340AT is a VGA-format, single-chip CMOS active-pixel digital image sensor for automotive applications. It captures high-quality color images at VGA resolution and outputs NTSC or PAL interlaced composite video. The VGA CMOS image sensor features ON Semiconductor’s breakthrough low-noise imaging technology that achieves superior image quality (based on signal-to-noise ratio and low-light sensitivity) while maintaining the inherent size, cost, low power, and integration advantages of ON Semiconductor’s advanced active pixel CMOS process technology. The ASX340AT is a complete camera-on-a-chip. It incorporates sophisticated camera functions on-chip and is programmable through a simple two-wire serial interface or by an attached SPI EEPROM or Flash memory that contains setup information that may be loaded automatically at startup. The ASX340AT performs sophisticated processing functions including color recovery, color correction, sharpening, programmable gamma correction, auto black reference clamping, auto exposure, 50Hz/60Hz flicker detection and avoidance, lens shading correction, auto white balance (AWB), and on-the-fly defect identification and correction. The ASX340AT outputs interlaced-scan images at 60 or 50 fields per second, supporting both NTSC and PAL video formats. The image data can be output on one or two output ports: Composite analog video ...
