The OV7950 is a highly integrated CMOS video camera that packs a high level of functionality. It is the new generation of advanced CMOS image sensors developed specifically for automotive applications, performing exceptionally well in low light conditions (< 0.01 lux) and in a wide temperature range (from -40ºC to 105ºC.)

At only 1/4 inch square and using only one 3.3 volt DC power supply, the OV7950 color sensor is ideal for applications requiring a small footprint, low power consumption, high performance video camera. The OV7950 supports NTSC composite video output and can directly interface with an in-car LCD screen or other device with 75 Ohm loading.

Key features of the OV7950 include a new windowing feature which allows customers to adjust their camera setup by moving the sensitive area of the camera in either vertical or horizontal directions. This feature of OV7950 is especially useful in fine tuning the viewing window and angle of fixed position cameras, for example cameras mounted in places where there is a chance of obstructed views such as on car bumpers.

The OV7950 image sensor is particularly well suited to automotive applications because it 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.

The OV7950 has been submitted for full AEC-Q100 certification for automotive applications.
