Compact automotive camera platform delivers high-quality images
In a joint development effort, digital imaging solutions provider Omnivision and automotive camera video processor vendor GEO Semiconductor have developed a system which, according to the claims of the two partners, will deliver the industry’s highest quality images for rear-view cameras (RVCs), surround-view systems (SVS) and e-mirrors.

The solution includes OmniVision’s OX03C10, which combines a large 3.0 micron pixel,  high dynamic range (HDR)  of 140dB for minimized motion artifacts, and the highest LED flicker mitigation (LFM) performance. It takes advantage of the GEO GW5 CVP family’s ability to process 140dB HDR images with full LFM at 60 frames per second (fps). Conversely, the GW5 family’s advanced local tone mapping enables it to make optimal use of the OX03C10’s HDR and LFM image captures.

This sensor’s integration of OmniVision’s HALE (HDR and LFM engine) combination algorithm provides the highest HDR and LFM performance simultaneously, while its Deep Well dual conversion gain technology significantly reduces motion artifacts. The OX03C10 is also the first viewing image sensor with HDR and LFM that can deliver 1920x1280p resolution at a frame rate of 60 fps, enabling greater design flexibility and faster camera-view switching for drivers. With the lowest power consumption of any 2.5MP LFM image sensor—25% lower than the nearest competitor—along with the industry’s smallest package size, the OX03C10 enables the placement of cameras that continuously run at 60 fps in very tight spaces.

The GW5 CVP family integrates an innovative HDR image signal processor (ISP) that supports the simultaneous 140dB HDR and industry’s highest LFM output of the OX03C10, providing high image detail in scenes with both bright and dark areas. Additionally, the GW5 includes GEO’s 5th-generation eWARP geometric processor to dewarp fisheye lenses exceeding a 180 degree wide field of view. The GW5 reduces system complexity and cost by requiring no external DDR memory and supporting dual sensor input that can process the captures from two OX03C10 sensors simultaneously.

 OmniVision’s OX03C10 image sensor is available for sampling, and GEO’s GW5 CVP family is in mass production. Both companies’ devices provide advanced ASIL functional safety and AEC-Q100 Grade 2 certification for automotive applications.
