OMNIVISION’s OV40A is a 40MP, 1.0 micron pixel image sensor that features super high gain and de-noise technologies for the best-in-class low light camera performance in the 1/1.7” optical format. This sensor also offers multiple HDR options for the best quality still and video captures. It supports 1080p high-speed video captures at 240 frames per second (fps) with phase-detection autofocus.
The OV40A provides super high gain of up to 256x, and is embedded with multi-sampling de-noise functionality for enhanced low light performance. This sensor also offers excellent HDR through selective conversion gain for the optimum balance between low-light image quality and HDR, along with 2- and 3-exposure staggered HDR timing. These features provide designers with maximum flexibility to select the best HDR method for the contrasting light and dark areas in a given scene.
Built on OMNIVISION’s PureCel®Plus-S stacked die technology, the OV40A uses a 4-cell (4C) color filter array and features on-chip re-mosaic, for high quality, 40MP Bayer output in normal light conditions. For low light conditions, this sensor can use near-pixel binning to output a 10MP image, as well as 4K2K video, with four times the sensitivity, yielding 2.0 micron pixel-equivalent low-light performance. In either case, the OV40A can consistently capture the highest quality images for different resolution video modes through fast mode switch.
Output formats include 40MP at 30 fps, 10MP with 4C binning at 120 fps, 4K2K video at 60 fps and 1080p video at 240 fps. All of these formats can be captured with phase-detection autofocus. Other features include a CPHY interface, multi-camera sync and a 34.7 degree chief ray angle.
