OMNIVISION launches OVMed Image Signal processor

OMNIVISION has announced the OVMed OH0131 image signal processor (ISP), an easy-to-implement solution for reusable and disposable endoscopes connected to handheld tablet consoles or camera control units (CCUs).

It supports all OMNIVISION medical image sensors up to 2-megapixel (MP) resolution, including the popular OCHTA, OVM6946, OCHFA, OCHSA and OCH2B imagers.

Off-the-shelf, the OVMed OH0131 streamlines engineering for medical OEMs, while the ability to purchase a medical-grade image sensor with wafer-level optics, cable and ISP from one vendor also simplifies the supply chain.

The OH0131 ISP is based on an ASIC system-on-chip (SoC) for the highest image quality, reliability and cost-effectiveness, and is compatible with all the company’s existing medical imagers that are 2MP and lower in resolution.

The OH0131 supports OMNIVISION’s proprietary AntLinx CMOS chip-on-tip endoscopy imaging interface and MIPI interfaces. It serves as a kernel board to integrate with any MIPI-input post-processing board by an SoC, FPGA or x86 platform to build custom CCUs or handheld tablet consoles.

The OH0131 kernel features the latest state-of-the-art image pre-processing algorithms supporting brightness, contrast, saturation, sharpness, hue, white balance and gamma adjustment with advanced noise reduction.

Post processing is performed by a third-party partner, utilising an SoC or FPGA, and will target (but is not limited to) LED drivers, patient isolation, high dynamic range, image rotation, image mask/onscreen display, H.264 compression, high-definition multimedia interface, and Wi-Fi output.

The OVMed OH0131 is now available and OMNIVISION plans to put the ISP through IEC 60601 EMC and EMI pre-scan testing.

The miniature board is available in a small form factor of 63 mm x 51 mm.
