OmniVision Technologies, Inc. has claimed the industry’s first 64 megapixel (MP) image sensor with a 0.7 micron pixel size, enabling 64-MP resolution in a 1/2” optical format for the first time. The new OV64B allows designers to create the thinnest smartphones with high-resolution 64-MP cameras, and can be used for main, wide, ultra-wide or telephoto rear-facing cameras in multi-camera configurations.

Delivering excellent still image captures and 4K video recordings with electronic image stabilization (EIS), as well as 8K video at 30 frames per second (fps), the OV64B built on OmniVision’s PureCel Plus stacked die technology, supports 3-exposure, staggered HDR timing for up to 16-MP video modes. It integrates a 4-cell color filter array and on-chip hardware re-mosaic, which provides high quality, 64-MP Bayer output in real time.

OmniVision said in low light conditions, the sensor can use near-pixel binning to output a 16-MP image with 4x the sensitivity, offering 1.4-micron equivalent performance for previews and still captures, and consistently capture the best quality images, while enabling 2x digital crop zoom with 16-MP resolution and fast mode switch.

The sensor features type-2, 2×2 microlens phase detection autofocus (ML-PDAF) for better autofocus accuracy, especially in low-light conditions. It also provides a CPHY interface for greater throughput using fewer pins, and supports slow motion video for 1080p at 240 fps and 720p at 480 fps. Other output formats include 64 MP at 15 fps, 8K video at 30 fps, 16 MP captures with 4-cell binning at 30 fps, 4K video at 60 fps, and 4K video with EIS at 30 fps.

Samples of the OV64B image sensor will be available in May.
