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-in. 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 three-exposure, staggered HDR timing for up to 16-MP video modes. It integrates a four-cell color filter array and on-chip hardware re-mosaic, which provides high-quality, 64-MP Bayer output in real time.
OmniVision said that in low-light conditions, the sensor can use near-pixel binning to output a 16-MP image with 4× the sensitivity, offering 1.4-micron-equivalent performance for previews and still captures, and consistently capture the best-quality images while enabling 2× 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 four-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.
