Phase-detecting 50Mpixel sensor supports autofocus
OmniVision has introduced a 50-megapixel CMOS image sensor that includes quad phase detection (QPD) to support autofocus in smartphones.

The OV50A has a 1.0micron pixel size and 1 by 1.5inch optical format for premium still picture and 8K video capture.

The QPD enables 2 by 2 phase detection autofocus (PDAF) across the sensor’s entire image array, for 100 percent coverage.

The OV50A image sensor also offers good low-light performance due to the combination of a large 1.0 micron pixel size, selective conversion gain’s low-noise, high conversion gain mode, and the large 1/1.5”optical format. Additionally, the sensor offers high-dynamic range through two- and three-exposure staggered HDR timing.

The sensor can also use near-pixel binning to output a 12.5-megapixel image for 4K2K video with four times the sensitivity, yielding 2.0 micron-equivalent performance for preview and video.

Output formats include 50MP, or 8K video, with QPD autofocus at 30 frames per second (fps), 12.5MP with QPD autofocus at 60fps, 4K2K video with QPD autofocus at 90fps, 1080p at 240fps and 720p at 480fps. All of these options can be output at up to 3.5 Gsps per trio, over the sensor’s CPHY MIPI interface.

OV50A samples are expected in Q2 2021.
