Boise, Idaho Delivering a smaller form factor, Micron Technology, Inc. touts that its 1/4-inch, 2-megapixel CMOS image sensor not only enables mainstream camera phones to capture higher quality digital pictures, but it is also the first to incorporate the Mobile Industry Processor Interface (MIPI) standards into an image sensor, allowing cameras to be more easily designed into mobile phones.
Until recently, VGA (640 by 480 pixels) has been the dominant resolution in camera phones, but it has not lived up to consumer expectations when printed, said the company. However, Micron believes its smaller MT9D112 2-megapixel (1,600 by 1,200 pixels) image sensor will allow users to take and print true, vibrant pictures for 4 x 6-inch up to 8.5- x 11-inch formats.
The MT9D112, developed using the company's 2.2-micron pixel technology, incorporates the company's proprietary DigitalClarity technology. This fully integrated system-on-chip (SoC) sensor includes an integrated microcontroller that is said to achieve more efficient image processing, a global reset to avoid image tearing, and pixel binning for enhanced image viewing. The microcontroller also increases the device's flexibility to adjust color and other image processing functions, and an integrated auto focus saves time, design cost and space typically incurred by a second companion chip, explained the company.
The sensor is capable of 15 frames per second (fps) at full resolution and 30 fps in video mode. The maximum data rate is 80 megapixels per second at 80 MHz. The signal-to-noise ratio is 37.7 dB maximum. In addition, it supports both a parallel interface as well as the MIPI serial interface (both CSI-2 and D-PHY).
Micron will showcase its MT9D112 2-megapixel, 1/4-inch CMOS image sensor along with its complete mobile handset image sensor portfolio at the 3GSM World Congress, February 13-16, 2006 in Barcelona, Spain. Click here for more information on Micron's CMOS image sensors.
Sampling is planned for April 2006, with mass production expected in August 2006. Pricing is approximately $9.50 each in quantities of 10,000.
