GPU image processing for OH02B10 image sensor from OmniVision

OmniVision's OH02B10 is a square 2-megapixel, 1500×1500 resolution CMOS image sensor for medical applications: gastrointestinal, ENT, orthopaedic, surgical, dental and veterinary reusable and disposable endoscopes, catheters and guidewires. The OH02B10's miniature square form factor saves space for higher resolution in smaller designs. It allows endoscopes to have a smaller outer diameter (6mm) or larger working channels for advanced endoscope designs. The OH02B10 is based on OmniVision's latest PureCel®Plus-S stacked die technology, which enables high functionality in the smallest possible die size.

The OH02B10 image sensor is available in the CameraCubeChip® package, which features a small 2.5mm×2.5mm size with extremely high image quality for disposable endoscope designs. It features OmniVision's proprietary AntLinx™ technology, which provides the thinnest 4-metre interface connection directly from the endoscope camera to the camera control tower. AntLinx™ delivers superior video quality and reduces interface conversion requirements, even in long-reach applications such as gastrointestinal endoscopy.

The OCH2B10 camera module is autoclavable and requires no adjustment or calibration. OmniVision is ISO13485 certified and medical products are EMC and EMI tested, which helps streamline the FDA approval process for medical device OEMs. The OCH2B10 is biocompatible and waterproof.
