Image signal processors target endoscopes and catheters

OmniVision Technologies, Inc. has expanded its OVMed family of medical image signal processors (ISPs) with the launch of the OH0120 and OH0130 ASIC-based boards. These ISPs are designed to operate with the company’s high performance medical image sensors for quick integration into single-use and reusable endoscopes as well as catheters.

The OH0120 provides an off-the-shelf, board-level option with HDMI connectivity, LCD screen support, and USB memory-card storage. The OH0130 supports all of OmniVision’s HD and analog medical image sensors thanks to dual inputs for either a MIPI interface or a 4-wire analog interface, enabling customers to expand to full HD imaging with no ISP system redesign, according to OmniVision.

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

The OH0130 is designed 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. Key features include USB 3.0 Type C connectivity, HD output, and a small form factor that can fit into the handle of a larger endoscope or into a CCU. The OH0130 also includes an LED control board that can adjust the image brightness. Applications include a range of endoscopic procedures, including airway management and urology.

The OH0120 and OH0130 are both medically pre-certified to comply with IEC 60601 (ESD, EMC, EMI, patient isolation). They also are compliant with REACH and RoHS, and are manufactured in facilities certified to the ISO 13485 and ISO 9001 standards.

Samples of OmniVision’s new OH0120 and OH0130 OVMed ISP boards are available now. A software development kit (SDK) is available to speed the design of interfaces and applications.
