Micron Introduces First Anti-Shake 3-Megapixel Camera SoC For Mobile Phones
Micron Technology unveiled a 1/4-inch, 3-megapixel complete camera system-on-chip sensor for mobile handsets. Unique to the market, Micron has designed an anti-shake feature into the sensor, which reduces image blurring often found in camera phone pictures due to camera shake.
Blurry images are especially common in low-light situations where the shutter is open for longer periods of time to collect enough light to take the picture. A camera phone designed with Micron’s new sensor (product number MT9T111) can reduce image blur by automatically activating the anti-shake feature when sensing camera shake.
Micron offers several 3-megapixel image sensors in differing optical formats, but this new sensor is the first in its class with the anti-shake feature. The new 3-megapixel sensor was developed on Micron’s 1.75-micron pixel and integrates additional camera capabilities on chip including JPEG compression and image processing that would typically require additional chips. For basic operation, the sensor only requires a power supply, lens and clock source.
General customer sampling is planned for August 2007 with mass production expected in the fourth quarter of 2007.
