Processor board augments endoscopic imaging
Omnivision’s OVMed OH0131 image signal processor (ISP) works with both reusable and disposable endoscopes connected to tablets or camera controllers. The OH0131 kernel employs image pre-processing algorithms supporting brightness, contrast, saturation, sharpness, hue, white balance, and gamma adjustment with advanced noise reduction.
The OH0131 ISP is compatible with all Omnivison medical image sensors with resolutions up to 2 Mpixels, including the OCHTA, OVM6946, OCHFA, OCHSA, and OCH2B imagers. It provides the company’s proprietary AntLinx CMOS chip-on-tip endoscopy imaging interface, as well as MIPI interfaces, for easy implementation.
The image signal processor serves as a kernel board for integration with any MIPI-input post-processing board. This combination of pre- and post-processing boards can be used to build custom handheld tablet consoles or camera control units.
“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, Omnivison. “The OH0131 ISP is based on an ASIC system-on-chip for the highest image quality, reliability, and cost-effectiveness.”
The OVMed OH0131 63×51-mm board is available now. IEC 60601 EMC and EMI pre-scan testing of the ISP is planned.
