OMNIVISION’s OV20880 is an ultra-compact image sensor designed specifically to bring 20 megapixel resolution to high-end, dual-camera mobile zoom solutions using OMNIVISION’s second-generation, 1.0‑micron PureCel®Plus-S pixel technology. The OV20880 offers advanced features such as zig-zag high dynamic range (zHDR), phase detection autofocus (PDAF), and support for dual-camera functionality with context switching, scaler and electronic image stabilization (EIS). The on-chip EIS also enables advanced capabilities such as image deblur.
zHDR uses a long and a short exposure in a single frame to extend dynamic range capabilities of the sensors. Long and short exposure lines are diagonally interlaced across the entire pixel array in a zig-zag pattern. This enables live preview and video recording in HDR mode and single-shot full-resolution HDR images in capture mode without any shutter lag.
The OV20880 captures full-resolution 20 megapixel images and video with zHDR capability at 30 fps, ultra-high-resolution 4K2K video with full field-of-view at 60 fps, and 1080p high definition (HD) video at 120 fps. The OV20880 offers both MIPI D-PHY and C-PHY interfaces.
The OV20880 comes in a package size of 8.5 x 8.5 mm with a z-height of 5.3 mm.
