Medical image signal processor with a shorter time to market

“Due to the continued push for smaller CMOS image sensors in endoscopes, most signal processing has to be executed on a separate ISP chip, either inside the endoscope handle or within the camera control unit. The OVMed solution integrates the analogue-to-digital converter, ISP and output interface to streamline the signal conditioning and processing architectures of endoscope designs,” said Tehzeeb Gunja, Principal Marketing and Business Development Manager at OmniVision.

“When coupled with our portfolio of compact, high performance medical CMOS image sensors, the OVMed ISP provides customers with an end-to-end, proven solution that is market-ready and cost effective.”

The OVMed ISP system’s video processing unit comes in two versions. The Mini version is compact enough to fit inside an endoscope handle, which is ideal for mobile, ambulatory or other environments that connect directly to a tablet or PC. The larger, Advanced version provides the highest image quality with more sophisticated features and can reside in the camera control unit.

The OVMed ISP is available in multiple output formats and interfaces, depending on the desired application. The output can connect to an external display via USB or HDMI cables, or wirelessly via WiFi. Alternatively, the unit can interface with a microcontroller via a DVP port.

The OVMed ISP system offers image signal processing with a short system delay of less than 100ms, enabling instantaneous image capture and display even when connected via WiFi. With power consumption at only 300mA in active mode, it can run on a battery or via a USB power adaptor.  

The OVMed ISP can be easily integrated with a wide variety of hardware and software. Endoscope designers can define configurable hardware buttons and LED indicators, based on their applications’ specific requirements. The included Software Development Kit (SDK) runs on Android, iOS, macOS and Windows, and features APIs with a C++ callable function library in binary DLL format.

The SDK also provides demo programmes that illustrate how to use the APIs. The optional WiFi module can be controlled via the included application, using any iOS- or Android-based mobile device.

The OVMed ISP meets the ESD, EMC and EMI specifications required by the IEC 60601 standard. It is also certified as REACH and RoHS compliant, and qualifies for CE marking. Additionally, its software complies with the IEC 62304 standard.
