Micro CMOS image sensors introduced

JUNE 4--IC Media Corp. (San Jose, CA; www.ic-media.com) has developed two micro-sized CMOS image sensors with an integral lens for built-in camera applications such as cellular phones, toys, PDAs, and watches. Both sensors also can be used in still-picture and full-motion video camera applications.

The ICM-105Ala CMOS image sensor offers 640 x 480-pixel (VGA) resolution, whereas the ICM-102Ala CMOS image sensor delivers 352 x 288-pixel (CIF) resolution. Combining a lens with each sensor reduces the camera module size for the ICM-105Ala to 8 x 8 x 8 mm and for the ICM-102Ala to 8 x 8 x 5.8 mm.

The ICM-105Ala can capture still pictures or motion video at up to 30 frames/s, draws less than 30 mA at 30 frames/s, and provides 6 x 6-μm pixels. It uses a 0.25-in., two-piece lens structure with f/2.5, a 4.8-mm focal length, a 57° view angle, and a 50% modulation transfer function (MTF).

The ICM-102Ala features a similar design but with a 1/7-in. lens in a one-piece plastic housing, an infrared filter, f//2.8, a 2.7-mm focal length, a 56° viewing angle, and a 60% MTF. It draws 25 mA at 30 frames/s.
