Omnivision has expanded its OVMed family with the introduction of the OH0131 image signal processor (ISP) for reusable and disposable endoscopes connected to handheld tablet consoles or camera control units (CCUs). The ISP supports Omnivision’s medical image sensors, up to 2-megapixel (MP) resolution, including the OCHTA, OVM6946, OCHFA, OCHSA and OCH2B.
By providing the medical-grade image sensors with wafer-level optics along with the cable and ISP from one vendor, it simplifies the supply chain for medical OEMs, Omnivision said.

The OH0131 ISP is based on an ASIC system-on-chip (SoC) for high image quality and high reliability as well as cost-effectiveness. It supports Omnivision’s proprietary AntLinx CMOS chip-on-tip endoscopy imaging interface and MIPI interfaces. It can integrate with any MIPI-input post-processing board by an SoC, FPGA or x86 platform to build custom CCUs or handheld tablet consoles.
Omnivision said the OH0131 kernel features the latest state-of-the-art image pre-processing algorithms that support brightness, contrast, saturation, sharpness, hue, white balance and gamma adjustment with advanced noise reduction. Post processing performed by a third-party partner using an SoC or FPGA can target features such as 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 image signal processor is available now. The ISP will undergo IEC 60601 EMC and EMI pre-scan testing. The miniature board measures 63 mm × 51 mm.
