Low-Power Sensor

OmniVision Technologies (Santa Clara, CA) offers the OV6930 medical image sensor. It is a low-power, 400 × 400 pixel square graphics array, or SquareGA™, CMOS image sensor with an optical format of 1/10”, and a packaged footprint of 1.8 × 1.8 mm. It is designed for camera applications that require less than 2.8-mm outside diameter, such as medical endoscopes for minimally invasive procedures.

The sensor uses a three-micron OmniPixel3-HS™ pixel for low-light performance of 3300 mV/Lux-second. It provides fullframe or cropped analog images in RAW RGB format via the control of a serial I/O, which allows for two-wire cabling up to 14'. It has power consumption of 80mW with, and 10mW without I/O usage. It also features an image array capable of operating at 30 frames per second in full resolution, and 60 fps at 400 × 200 resolution. Proprietary sensing technology reduces or eliminates fixed pattern noise and smearing.
