The Micron® Imaging MT9M111I29STC is an SXGA-format single-chip camera with a 1/3-inch CMOS active-pixel digital image sensor. This device combines the MT9M011 image sensor core with fourth-generation digital image flow processor technology from Micron Imaging. It captures high-quality color images at SXGA resolution.

The MT9M111I29STC features DigitalClarity, Micron's breakthrough, low-noise CMOS imaging technology that achieves CCD image quality (based on signal-tonoise ratio and low-light sensitivity) while maintaining the inherent size, cost and integration advantages of CMOS.

The sensor MT9M111I29STC is a complete camera-on-a-chip solution designed specifically to meet the low-power, lowcost demands of battery-powered products such as cellular phones, PDAs, and toys. It incorporates sophisticated camera functions on-chip and is programmable through a simple two-wire serial interface.

The MT9M111I29STC performs sophisticated processing functions including color recovery, color correction, sharpening, programmable gamma correction, auto black reference clamping, auto exposure, automatic 50Hz/60Hz flicker avoidance, lens-shading correction, auto white balance (AWB), and on-the-fly defect identification and correction. Additional features of MT9M111I29STC include day/night mode configurations; special camera effects such as sepia tone and solarization; and interpolation to arbitrary image size with continuous filtered zoom and pan. The device supports both Xenon and LEDtype flash light sources in several snapshot modes.

The MT9M111I29STC can be programmed to output progressive- scan images up to 30 frames per second (fps) in preview power-saving mode, and 15 fps in full-resolution (SXGA) mode. In either mode, the image data can be output in any one of six 8-bit formats:
• ITU-R BT.656 (formerly CCIR656, progressive scaonly) YCbCr
• 565RGB
• 555RGB
• 444RGB
• Raw Bayer
• "Processed" Bayer The FRAME_VALID and LINE_VALID signals are output on dedicated pins, along with a pixel clock that is synchronous with valid data.
