OMNIVISION’s OVMed Image Signal Processor Used in ATL Medical’s PREVOYANCE System

ATL Medical Inc. is using OMNIVISION’s OVMed OH0131 image signal processor (ISP) in its PREVOYANCE Complete Imaging System with chip-on-tip technology for arthroscope camera units.

ATL Medical’s PREVOYANCE is a complete medical visualization assembly for customers wanting a turnkey “white label” device that delivers high image quality to enable faster time-to-market at a lower cost, according to the company. It is often paired with a full-featured camera control unit (CCU) for imaging, processing, and storage. OMNIVISION’s OVMed OH0131 ISP is purpose-built for medical imaging and is designed for easy implementation in handheld tablet consoles or CCUs. It supports multi-image configurations and addresses critical medical visualization requirements such as precise color fidelity, advanced noise reduction, and stable performance across varying illumination conditions.

“The top challenges in medical ISPs center on delivering real-time, high-fidelity visualization while overcoming extreme environmental factors such as specular reflections, smoke, blood, and shadows. Key obstacles include maintaining low-latency processing, handling high-volume data, and achieving accurate, automated segmentation and feature extraction during complex procedures,” said Ehsan Ayar, senior staff marketing manager for OMNIVISION’s medical segment.

OMNIVISION and ATL Medical collaborated to provide a complete imaging solution consisting of a kernel board and a host:

• The kernel board, designed by OMNIVISION, includes the OH0131 medical-grade ISP that receives raw images from the image sensors, processes them, and forwards them to the host through a MIPI interface.
• The host, designed by ATL, receives the images and displays them on the screen connected to the HDMI port.

ATL Medical complements the imaging subsystem with full system-level device integration, including optics, illumination, cabling, interconnects, distal-end fabrication, and ergonomic handle design. This end-to-end capability allows OEMs to accelerate development timelines, reduce engineering risk and deploy imaging solutions that can be used as standalone systems or be integrated into existing platforms.

“We are pleased to collaborate with OMNIVISION and leverage their expertise in advanced image processing for the PREVOYANCE platform,” said Mike Anderson, vice president strategy, ATL Medical. “We’ve developed an off-the-shelf CCU that can be deployed standalone or be integrated into a customer’s existing platform, simplifying their design cycle while also improving the overall performance of their solution.”

The OVMed OH0131 ISP was originally launched in 2023 and has the following medical certifications: ISO 13485, RoHS, REACH, IEC 60601 (ESD, EMC, EMI, isolation), and EMS ISO 9001. It supports the full range of OMNIVISION medical image sensors, from 2-megapixel (MP) down to 200 x 200 resolution. It also supports OMNIVISION’s proprietary AntLinx CMOS chip-on-tip endoscopy imaging and MIPI interfaces.

OMNIVISION is a global, fabless semiconductor organization that develops advanced digital imaging, analog, and display solutions for multiple applications and industries, including mobile phones, security and surveillance, automotive, computing, medical, machine vision, and emerging applications. Its technologies enable a smoother human/machine interface in many current commercial devices.
