Camera phone imager cures the shakes

Offers 2-Mpixel resolution and high dynamic range in 1/5-in. format

Using advanced image signal processing (ISP) and third-generation 1.75-mm pixel technology, the 2-Mpixel OV2650 CameraChip CMOS image sensor not only offers best-in-class low-light performance (520 mV/lux-s), but also integrates image stabilization the kind of anti-shake capability seen in digital still cameras (DSCs). Thus the device is another signpost on the road to the end of stand-alone DSCs, and it will likely find application in toys as well.

Anti-shake capability is particularly important because capturing images in low light levels generally requires slow shutter speeds and holding the camera still longer. Taking advantage of the sensor’s high dynamic range (85 dB) and ultralow noise, the ISP lets the imager handle extreme bright and dark areas within the same scene and adjust rapidly to changes in light conditions.

The unit is said to offer superb color reproduction, and its 1/5-in. optical format makes it compact enough to upgrade existing 1.3-Mpixel and VGA phone designs. An integrated high-speed MIPI (mobile industry processor interface) allows rapid transfer of large blocks of data to ease picture sharing.
