4K2K image sensor for home and professional security cameras
Omnivision has launched a small image sensor with on-chip defective pixel correction to improve image quality.
The OS08C10 is an 8MPixel resolution, small-form-factor image sensor with on-chip staggered pixels and correction technology to boost video/image quality in challenging lighting environments
The sensor uses backside illumination (BSI) with both staggered high dynamic range (HDR) and single exposure dual analog gain (DAG) for high-performance imaging in challenging lighting conditions. The 1.45-micron (µm) BSI pixel supports 4K2K resolution and high frame rates. It comes in a small 1/2.8-inch optical format, a popular size for home and professional security, IoT and action cameras.

“Our new 1.45 µm pixel OS08C10 image sensor provides improved sensitivity and optimized readout noise, closing the gap with big-pixel image sensors that have traditionally been required for high-performance imaging in the security market,” said Cheney Zhang, senior marketing manager at Omnivision.
“The OS08C10 supports both staggered HDR and DAG HDR. Staggered HDR extends dynamic range in both bright and low lighting conditions; the addition of built-in DAG provides single-exposure HDR support and reduces motion artifacts. Our new feature-packed sensor supports 4K2K resolution for superior image quality with finer details and enhanced clarity.”
The OS08C10 captures real-time 4K video at 60 frames per second (fps) with minimal artifacts. Its selective conversion gain (SCG) pixel design allows the sensor to flexibly select low and high conversion gain, depending on the lighting conditions.
The sensor adopts a new correlated multi-sampling (CMS) to further reduce readout noise and improve SNR and low-light performance. The on-chip defective pixel correction (DPC) improves quality and reliability above and beyond standard devices by providing real-time correction of defective pixels that can result throughout the sensor’s life cycle, especially in harsh operating conditions.
The OS08C10 is sampling now and will be in mass production in Q1 2024.
