Omnivision Announces 11.3MP HDR Security Sensor, VGA Sensors with 2.2um GS Nyxel Pixels

PRNewswire: OmniVision announces the OS12D40, a 1.4um pixel, 11.3MP image sensor with on-chip remosaic (4-cell to Bayer) color converter and on-chip HDR processing. When in full-HD 1080p mode, this sensor's 3-exposure HDR with on-chip combination and tone mapping provides best in class video captures. This is superior to the competing method, known as staggered HDR, which relies on additional passes that introduce motion artifacts, especially in low light. Additionally, OmniVision's PureCel Plus-S stacked architecture enables each pixel to perform optimally to further improve HDR in scenes with widely contrasting bright and dark areas.

"With this new image sensor, we're setting the standard for best in class, mass market security camera performance," said David Shin, product marketing manager for the security segment at OmniVision. "This means both commercial and home security systems will now be able to better capture moving objects across all lighting conditions in full-HD 1080p mode, while using artificial intelligence (AI) or human operators to selectively take 4K2K images without HDR. The latter is important when the need for greater detail is identified, such as capturing an intruder's facial features or reading a car's license plate number. Additionally, we achieve 2.8 micron-equivalent pixel performance using 4-cell binning, to provide excellent low light image quality in 1080p mode."

Industry analysts predict that the security and surveillance camera market is growing at a more than 15% CAGR, and will exceed 400M units in 2024.

Other features include a large 1/2.49" optical format, 9 degree CRA, a 10b ADC and a 4-lane MIPI transceiver (2.5 Gbps/lane).

Integrated selective conversion gain technology allows the pixel conversion gain to be dynamically switched between low and high, depending on the scene being captured in combination with the sensor's other features, including PureCel Plus-S stacked pixel technology for reduced crosstalk and maximum QE.

The OS12D40 uses a 4-cell color filter pattern. It has an on-chip 4-cell to Bayer remosaic converter, in order to provide 4K video at 60fps with 20% additional pixels for EIS. In a 4-cell binned mode, it can output an impressive 2.8MP/1080p resolution with 20% additional pixels for EIS video and images at four times the sensitivity. This sensor also supports both CPHY and DPHY interfaces, and can output 11.3MP, 4512x2512 16:9 captures at 60fps, 4K video at 60fps and 1080p video at 240fps.

OS12D40 samples are available now in a fan-out and chip-scale wafer level package.

PRNewswire: OmniVision announces the expansion of its BSI GS sensor family with new VGA imagers that feature the industry's smallest pixel size of 2.2um—the OG0VA image sensor and OC0VA CameraCubeChip™ wafer-level camera module. Additionally, the OC0VA is the first CameraCubeChip with Nyxel technology. They have a high QE of 40% at 940nm and 60% at 850nm.

The OG0VA image sensor provides 640x480 VGA resolution at 240fps and 320x240 QVGA resolution at 480 fps, in the optical format of 1/10 inches. The OC0VA CameraCubeChip combines this sensor with image signal processing and optics into a 2.69 x 3.04 x 3.04mm wafer-level camera module. Additionally, their low light sensitivity is excellent, with significantly lower gain than the industry's typical 3.0um pixel size for an improved SNR.

"There is a growing need for global shutter technology at a variety of resolution levels to accurately capture the images of moving objects, along with excellent NIR performance and small size," said Devang Patel, senior staff marketing manager for the security and emerging segments at OmniVision. "The OG0VA and OC0VA expand our family of the industry's smallest GS imagers by providing VGA resolution options with the best NIR performance in a global shutter device."
