OmniVision Technologies Inc. has released its all digital OV7710 CameraChip advanced CMOS image sensor developed specifically for automotive applications. The OV7710 is a highly integrated CMOS video camera that combines a high level of functionality with all digital output. Digital output is a key requirement for automotive machine-vision applications such as airbag deployment, lane departure warning, collision avoidance/pedestrian detection, windshield wiper control, and drowsiness detection.

The OV7710 features a dual dynamic overlay function allowing for both a dynamic and a static visual aid layer (text or graphics) within the image. This is especially useful for reference frames and guiding systems in backup and parking assist cameras for cars and trucks. A windowing feature allows users to adjust the camera setup by moving the sensitive area of the camera by a few pixels, which is especially useful in fine tuning fixed position cameras mounted in places where there is a chance of obstructed views such as car bumpers.

The OV7710 is a high performance 1/4 inch, single-chip VGA digital video camera that excels in low light conditions and can operate in a wide temperature range from -400C to 1050C. A black and white version (OV7211) is also available. Both meet all existing automotive market requirements in terms of performance, quality and reliability.

The OV7710 incorporates a 640-by-480 image array capable of operating at up to 30 frames per second (fps). The sensor technology utilises algorithms to cancel Fixed Pattern Noise eliminate smearing and significantly reduce blooming. The OV7710 also provides all existing required camera functions including exposure control, gain, white balance, windowing and more, which are programmable through the Serial Camera Control Bus interface. Other key features of the OV7710 are its low power consumption, progressive scanning, external frame sync (Genlock) capability and support for both 10bit raw data and 8bit YUV/RGB outputs.

Samples of the OV7710 are currently available in both QFP and CLCC package formats.
