OmniVision Launches All Digital Automotive CameraChip™ Sensor



by Jerrie Colish

OmniVision Technologies, a world leading supplier of CMOS image sensors, today announced the availability of its new 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 new 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 -40?C to +105?C. 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 x 480 image array capable of operating at up to 30 frames per second (fps). The sensor technology utilizes algorithms to cancel Fixed Pattern Noise (FPN), 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 (SCCB) interface. Other key features of the OV7710 are its low power consumption, progressive scanning, external frame sync (Genlock) capability and support for both 10-bit raw data and 8-bit YUV/RGB outputs.

OmniVision Technologies designs and markets high-performance semiconductor image sensors. Its OmniPixel and CameraChip products are highly integrated single-chip CMOS image sensors for mass-market consumer and commercial applications such as mobile phones, digital still cameras, security and surveillance systems, interactive video games, PCs and automotive imaging systems.
