Supports all OMNIVISION medical image sensors up to 2-megapixel (MP) resolution.

OMNIVISION, a global developer of semiconductor solutions, including advanced digital imaging, analog, and touch & display technology, has announced the new 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.

Streamlining Engineering for Medical OEMs

“Our off-the-shelf OVMed OH0131 streamlines engineering for medical OEMs, enabling customers to get their products to market faster. The ability to purchase a medical-grade image sensor with wafer-level optics, cable and ISP from one vendor also simplifies the supply chain,” said Richard Yang, senior staff marketing manager, OMNIVISION. “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 our 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 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 performed by a third-party partner utilizing an SoC or FPGA 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 available now; 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.
