The Industrial Camera Video Processor, GW4300, integrates GEO’s patented Geometric processor eWARP® with an advanced High Dynamic Range (HDR) Image Signal Processor (ISP), On-screen Display engine (OSD), Parallel, MIPI, and NTSC/PAL interfaces. The device incorporates a Tensilica® Xtensa processor along with peripheral and serial device interfaces for complete system integration.
The eWARP® processor is GEO’s fourth-generation version of the unique and highly patented geometric processor. The fully programmable geometric processor provides the flexibility and performance to correct complex lens distortion, enable electronic Pan/Tilt/Zoom, and manipulate viewing perspective in real time with sub-frame time latency. The eWARP® technology can create multiple detail views in a single pass generating a video stream with multiple virtual camera views. The eWARP® core also supports complex digital alignment and camera calibration using GEO’s AutoCal®.
The ISP provides High Dynamic Range (HDR) processing, spatial noise reduction, color processing, sharpening, and advanced 3A algorithms. The HDR technology applies different processing to each pixel of each video frame to pull out hidden detail in shadows and highlights while preserving color, local contrast, and natural appearance. The ISP supports HDR sensors that provide a dynamic range of up to 120dB revealing detail in both high-light and low-light areas of the scene simultaneously.
The On-screen Display (OSD) engine blends up to four layers of graphics with the video. The four layers can be a combination of both static and dynamic overlays. The static overlays enable text and logos while dynamic overlays are used for dynamic parking lines, active text, and animations. The OSD can support either RGB or YUV format.
