OmniVision Technologies has launched two dedicated image signal processors designed to pair with its medical image sensors for quick integration into single-use and reusable endoscopes as well as catheters.

The OH0120 provides a cost-effective, off-the-shelf, board-level option with HDMI connectivity and LCD screen support, as well as external USB memory-card storage. The OH0130 supports all of OmniVision’s HD and analog medical image sensors, enabling customers to expand to full HD imaging with no ISP system redesign.

“Our OVMed ISP family remains the medical industry’s most extensive offering, and is optimized to take full advantage of our medical image sensors,” said Richard Yang, senior staff marketing manager at OmniVision. “This broad portfolio provides medical device designers with an industry-leading feature set and image quality, along with comprehensive development resources that enable them to focus on differentiated post-processing algorithms.”

The OH0120 provides medical designers with a cost-effective solution for developing analog-input and HDMI-output systems with up to 720p resolution. It features LED light control and LCD-screen drivers for integrating the display directly into a handheld or rack-based camera control unit (CCU). The OH0120 also includes on-board memory and a USB 2.0 port for external memory cards with up to 64GB, which can store up to 30 hours of video recordings. These features, along with native support for Android applications, help designers get to market quickly.

The OH0130 offers a cost-effective option for creating a CCU system platform that can process higher, full-HD resolution images of up to 1080p from a broad range of image sensors with a single board. It accepts dual inputs for either a MIPI interface or a 4-wire analog interface, making it compatible with OmniVision’s entire portfolio of medical image sensors. The OH0130 offers these high performance features, along with USB 3.0 Type C, HD output, in a small form factor that can fit into the handle of a larger endoscope or into a CCU. USB-C connectivity enables developers to create their own
