GENERAL DESCRIPTION
The ON Semiconductor MT9V128 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 CMOS imaging technology that achieves near-CCD 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 MT9V128 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 Flash memory that contains setup information that may be loaded automatically at startup.
The MT9V128 performs sophisticated processing functions including color recovery, color correction, sharpening, programmable gamma correction, auto black reference clamping, auto exposure, 50 Hz/60 Hz flicker avoidance, lens shading correction, auto white balance (AWB), and on-the-fly defect identification and correction.
The MT9V128 outputs interlaced-scan images at 30 or 25fps, 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
The integrated lens correction and overlay generation for steering guidance eliminates expensive overlay processing that is usually required by an external DSP; this significantly reduces overall costs.
