BusinessWire: OmniVision announces the OV50A image sensor, combining 50MP, 1.0um pixel size, selective conversion gain and a 1/1.5”optical format with quad phase detection (QPD) AF and on-chip remosaic. QPD enables 2x2 PDAF across the sensor’s entire image array, for 100% coverage. Unlike the microlens and half-shield PDAF technologies, which only capture 3-6% of the phase detection data, QPD captures 100% of this data for improved distance calculation, faster autofocus and better low-light performance. 

One of the biggest selling points for mobile phones is camera performance, and they have been steadily closing the gap with DSLR cameras for years,” said Arun Jayaseelan, staff marketing manager at OmniVision. “Our QPD autofocus technology now makes that gap even smaller, by bringing DSLR level autofocus performance to smartphone cameras.

Additionally, this sensor offers excellent HDR through 2- and 3-exposure staggered HDR timing, along with selective conversion gain for the optimum balance between low-light image quality and HDR.

Built on OmniVision’s PureCel Plus-S stacked die technology, the OV50A integrates an on-chip, QPD color filter array and hardware remosaic, which provides improved autofocus performance along with high quality, 50MP Bayer output, or 8K video, in real time. This sensor can also use near-pixel binning to output a 12.5MP image for 4K2K video with four times the sensitivity, yielding 2.0um-equivalent performance for preview and video. 

Output formats include 50MP, or 8K video, with QPD autofocus at 30fps, 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.
