GW3400

The GW3400 integrates GEO’s patented eWARP® core with an Apical Image Signal Processor (ISP), Tensilica® Xtensa CPU, DDR3 interface, parallel and MIPI interfaces, providing a completely integrated camera system solution.

The GW3400’s fully programmable geometric processing engine provides the flexibility and performance to correct complex lens distortion, enable electronic Pan/Tilt/Zoom, and manipulate viewing perspective in real time with as little as 1/6th frame of latency. The eWARP® technology creates multiple detail views in a single pass resulting in a video stream with multiple virtual camera views. The eWARP® core also provides the capability to digitally align and calibrate cameras.

The GW3400 integrates an Apical ISP that provides High Dynamic Range (HDR) processing, spatial noise
reduction, temporal noise reduction, 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 dynamic range of up to 96dB allowing detail in low light as well as high brightness areas of the scene simultaneously.
