Boise, Idaho Micron Technology, Inc. is now sampling a 1/4-inch optical format, 1.3 megapixel complementary metal oxide semiconductor (CMOS) image sensor for SXGA cameras. While most 1/4-inch based camera-phone handsets today are used with VGA resolution, said the company, the new MT9M112 CMOS image sensor brings 1.3 megapixel SXGA resolution to camera phones in the same optical format and module form factor, while maintaining image quality at a much higher resolution.
Packing loads of features and functions onto a single chip, the fully integrated system-on-chip (SoC) sensor also incorporates additional logic on the device that simplifies the camera module design, related manufacturing processes, system integration, power management, and component count. The MT9M112 device also incorporates some advanced image processing features including three channel gamma correction, lens shading correction, and color correction. Automatic features include on-the-fly auto defect correction, as well as auto features for exposure, white balance, black reference, flicker avoidance, and color saturation.
The MT9M112 CMOS image sensor is capable of 15 frames-per-second (fps) at full resolution and 30 fps in preview mode. It has a pixel size of 2.8 micron square and contains 1,280 horizontal x 1,024 vertical active pixels (standard SXGA format). Click here for a datasheet.
A big advantage of the new device is that it enables mobile phone manufacturers to simply upgrade their existing 1/4-inch VGA cameras to one-quarter inch megapixel cameras in the same height and footprint. In addition, by including the necessary imaging and digital signal processing technology all on one chip, it requires fewer parts and potentially reduces design costs.

The new MT9M112, as with all Micron CMOS image sensors, uses Micron's proprietary low-noise, high-sensitivity DigitalClarity technology, which is said to deliver brilliant color images even under some of the poorest lighting conditions.
In addition, the camera control sequencer automates the camera's flash and video clip snapshots. Additional features include 2 by 2 pixel binning, programmable input/output slew rate, mechanical shutter support, and continuous, smooth zoom and pan, as well as day and night mode configurations.
Samples are available now, followed by volume production in December 2005. Pricing is about $8.00 each in quantities of 10,000.
