Sensor with 48Mpixels sets sights on smartphones
OmniVision Technologies Inc. has announced the OV48B, its first 48megapixel image sensor featuring a 0.8-micron pixel size to enable high resolution smartphone cameras in a half-inch optical format.

Built on OmniVision’s PureCel-Plus stacked die technology, the sensor provides still image capture and video performance for both mainstream and high end smartphones. The OV48B also digital crop zoom and a CPHY interface, making it suitubale for rear-facing cameras in multi-camera configurations, including main, wide angle and telephoto.

The announcement comes eight months after OmniVision announced its 24MP image sensor (see 24MP image sensors aim for high-end smartphone cameras ). The OV48B has been able to reduce the pixel size in an attempt to reduce cost.

The OV48B integrates an on-chip 4-cell color filter array and hardware re-mosaic, which provides 48MP Bayer output in real time. In low light conditions, this sensor can use near-pixel binning to output a 12MP image with four times the sensitivity. Additionally, it can be used with a wide field-of-view and a CPHY interface for dual- and tri-camera configurations with dedicated wide- and ultrawide-angle capabilities.

This new sensor also features both DPHY and CPHY MIPI interfaces and 2 by 2 microlens phase detection autofocus (ML-PDAF) to boost accuracy, especially in low light. Output formats include 48MP at 10 frames per second (fps), 12 MP with 4-cell binning at 30fps, 4K2K video at 60fps, 1080p video at 240 fps and 720p video at 480fps.

OV48B samples are available now, and volume production is expected in Q4 2019.
