World’s First 1.0 Micron 64MP Image Sensor for Best Low Light Performance in High End Phones

Posted Oct 15, 2020 by OmniVision Technologies

OmniVision, a leading developer of advanced digital imaging solutions, has released its new OV64A image sensor, offering 64 megapixel (MP) resolution with the largest pixel size in its class, at 1.0 micron, along with a class-leading optical format of 1/1.34”. Its large optics and high resolution provide premium low light performance for the wide and ultrawide main cameras in high end smartphones.

Additionally, the OV64A features 3-exposure, 4-cell HDR with on-chip combination and tone mapping, as well as a very fast frame rate, which work in tandem to eliminate motion artifacts and produce the best 64MP signal-to-noise ratio (SNR). This sensor also offers a 2- and 3-exposure staggered HDR timing option, providing smartphone designers with maximum flexibility to select the best HDR method for a given scene.

“TSR estimates there will be 322 million image sensors with 50MP, or higher resolution shipped to smartphone manufacturers in 2021, which presents a huge opportunity for OmniVision’s growing 64MP portfolio,” said Arun Jayaseelan, staff marketing manager at OmniVision. “Compared with our 0.8 micron 64MP image sensor, the OV64A’s 1.0 micron pixel size provides a more than 60% sensitivity increase, allowing for the greatest possible performance in low light conditions.”

Built on OmniVision’s PureCel® Plus-S stacked die technology, the OV64A integrates an on-chip, 4-cell (4C) color filter array and hardware remosaic, which provides high quality, 64MP Bayer output, or 8K video, in real time. In low light conditions, this sensor can use near-pixel binning to output a 16MP image for 4K2K video with four times the sensitivity, yielding 2.0 micron-equivalent low-light performance for preview and video. In either case, the OV64A can consistently capture the highest quality images, as well as enabling 2x digital crop zoom with 16MP resolution and fast mode switch.

Output formats include 64MP at 15 frames per second (fps), 16MP with 4C binning at 60 fps, and 4K2K video at 120 fps with the extra pixels needed for electronic image stabilization. This sensor also offers 8K video at 30 fps, 1080p at 240 fps and 720p at 480 fps. Other features include CPHY and DPHY interfaces, and 4C half-shield phase detection for fast autofocus support.

OV64A samples are available now, and mass production is expected in Q4.
