OV7955 NTSC product brief Driving Down the Cost of Rear-View Cameras lead free available in a lead-free package The OV7955 is a low-cost, high-performance analog and digital image sensor designed specifically for mainstream automotive applications. The AEC-Q100 Grade 2 qualified OV7955 offers superior low-light sensitivity in an ultra-compact module size, making it an ideal camera solution for rear-view, surround-view and blind spot detection systems. Additionally, the OV7955 offers features new to the automotive industry, including built-in memory for initialization, which reduces a camera's overall bill of materials and size. The crop and resize feature allows the same camera module to be designed into virtually any vehicle platform without requiring additional mechanical adjustments. Utilizing OmniVision's proprietary high-sensitivity OmniPixel(R)3-HS pixel architecture, the sensor offers industry-leading low-light sensitivity of 16 V/lux-sec and excellent signal-to-noise-ratio (SNR). The OV7955 features the industry's smallest AEC-Q100 qualified automotive package (a-CSPTM), measuring only 5.7 x 5.4 mm, and offers an operating temperature range of -40C and 105C.
