OmniVision and GEO Semiconductor today announced a joint product aimed at delivering high quality images for rear-view cameras (RVCs), surround-view systems (SVS) and e-mirrors.
The product includes OmniVision’s OX03C10, which combines a large 3.0 micron pixel, high dynamic range (HDR) of 140dB for minimized motion artifacts, and the high LED flicker mitigation (LFM) performance.
This image sensor takes full 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 industry-leading HDR and LFM image captures, providing a more pleasing image for drivers.
This sensor’s integration of OmniVision’s industry-leading HALE (HDR and LFM engine) combination algorithm provides high HDR and LFM performance simultaneously, while its Deep Well dual conversion gain technology significantly reduces motion artifacts.
Additionally, OmniVision’s split-pixel LFM technology with four captures provides the best performance over the entire automotive temperature range.
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 power consumption claimed to be 25% lower than any other 2.5MP LFM sensor, along with the industry’s smallest package size, it enables the placement of cameras that continuously run at 60 fps in even the tightest spaces.
OmniVision’s PureCelPlus-S stacked architecture enables pixel performance advantages in the OX03C10 over non-stacked technology, in addition to a smaller die and lower power consumption.
For example, 3D stacking allowed OmniVision to boost pixel and dark current performance, resulting in a 20% improvement in the signal-to-noise ratio over the prior generation of its 2.5MP automotive viewing sensors.
The GW5 CVP family integrates an HDR image signal processor (ISP) that supports the simultaneous 140dB HDR and industry’s highest LFM output of the OX03C10, providing great 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
