2K2K Image Sensor Offers 1:1 Aspect Ratio and Digital Watermarking

Omnivision recently released its first 2K2K (2048 × 2048) square resolution CMOS image sensor designed for security applications. The OS04E10 offers a 1:1 aspect ratio security wide-field-of-view (WFOV) and pass-through cameras, such as dome, fisheye, doorbell, and more. It also packs what’s claimed as the world’s first digital watermark capabilities, providing an integrated anti-spoofing feature to ensure the authenticity of the original video.

According to a 2022 report from Yole Group, the imaging market is expected to grow to $3.6 billion by 2027, and Omnivision is a top CMOS image security sensor supplier for that market.

“As the market leader for image sensors in the security market, we are pleased to launch Omnivision’s first square 2K2K image sensor that is developed specifically for 1:1 aspect ratio security system designs—the preferred design for AR/VR/MR pass-through and security wide-field-of-view applications,” said Devang Patel, marketing director at Omnivision. “We are also introducing the industry’s first digital watermarking anti-spoofing capability with the OS04E10 sensor.”

 According to the company, combining the OS04E10 with Omnivision’s OA7600 and OA8000 ASICs provides a packaged camera system with always-on and pre-roll video-recording capabilities.

The OS04E10 packs a 2-µm pixel with a 1/3.11-in. optical format designed around the company’s PureCel Plus technology, which helps mitigate noise and pixel crosstalk that results in a loss of spatial resolution. The integrated Nyxel near-infrared (NIR) technology allows the sensor to garner clear and crisp images in ambient and low-light conditions, and it helps extend battery life.

The sensor also features a two-exposure, staggered high-dynamic-range (HDR) mode to increase the dynamic range of images and video. It supports MIPI and LDVS interfaces.
