General Description
The Aptina ASX340/MT9V139 is a VGA-format, single-chip active-pixel digital image sensor for surveillance applications. It captures high-quality color images at VGA resolu-tion and outputs NTSC or PAL interlaced composite video.
The VGA image sensor features Aptina's breakthrough low-noise imaging technology that achieves superior image quality (based on signal-to-noise ratio and low-light sensi-tivity) while maintaining the inherent size, cost, low power, and integration advantages of Aptina's advanced active pixel process technology.
The ASX340/MT9V139 is a complete camera-on-a-chip. It incorporates sophisticated camera functions on-chip and is programmable through a simple two-wire serial inter-face or by an attached SPI EEPROM or Flash memory that contains setup information that may be loaded automatically at startup.
The ASX340/MT9V139 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 ASX340/MT9V139 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 (single-ended and differential output support)
- Parallel 8-10-bit digital.
