32-MP image sensor delivers advanced features for smartphones

OmniVision Technologies, Inc. released its first 0.8-micron pixel image sensor with 32-megapixel (MP) resolution, built on OmniVision’s PureCel Plus stacked-die technology. The new OV32A, with a 1/2.8-inch optical format, packs advanced features, including on-chip re-mosaic and near-pixel binning, to satisfy the demand for higher-resolution images in high-end smartphones.

OmniVision’s PureCel Plus technology uses finer nodes, said the company, to enable the smallest pixel pitch in the OV32A. Key features include a four-cell color filter array, on-chip re-mosaic, which can provide full-resolution, 32-MP Bayer output in normal lighting conditions. The OV32A can use near-pixel binning to output an 8-MP image with 4× the sensitivity in low-light conditions.

The high-resolution images are available in a variety of formats, including 32 MP at 15 frames per second (fps), 8-MP with four-cell binning at 60 fps, 4K2K video at 60 fps, 1080p video at 120 fps, and 720p video at 240 fps.

The pad locations on the top and bottom of the image sensor, which reduce the module size in the x-direction, makes it suitable for front-facing cameras in thin-bezel, infinity-display smartphones.

Samples will be available in March 2019. Contact sales for more information.
