OmniVision Group recently released a new OS05B CMOS image sensor and OS04L CMOS 4-megapixel (MP) image sensor. Among them, the OS05B combines pixel technology and quantum efficiency (QE) in a 5-megapixel design, suitable for professional and high-end consumer security cameras such as industrial and factory surveillance systems, network cameras, and high-end baby monitors. The OS05B uses a 1/2.78-inch optical format and a 2.0-micron BSI pixel design process based on PureCel Plus technology. The image sensor also features OmniVision's Nyxel near-infrared (NIR) technology for clear images in low-light conditions.
Compared to OS05A, OS05B has a 32% improvement in signal-to-noise ratio (SNR1) and a 24% improvement in quantum efficiency at 940 nm near-infrared wavelength. The OS05B also features selective conversion gain - high conversion gain increases sensitivity and reduces read noise levels while achieving the best signal-to-noise ratio in low light conditions; while low conversion gain enables higher full well in bright environments capacity. The OS05B captures high-resolution video at 60 fps and features double-exposure interlaced HDR support. OS05B supports MIPI and LVDS interfaces.
The OS04L brings 2K-resolution digital images and high-definition (HD) video to consumer security devices such as smart homes, doorbells, baby monitors, IP, and HD analog cameras. The 2.0-micron pixel size of the OS04L image sensor utilizes OmniVision's OmniPixel 3-HS technology.
OS05B and OS04L will be sampled in the fourth quarter of 2022 and put into mass production in the first quarter of 2023.
