Abstract: A dynamic image representation system comprising apparatus for sensing a dynamic scene and apparatus for providing a pixel count reduced dynamic digital representation of the scene having pixel count reductions in portions of the scene not fulfilling predetermined spatial criteria and pixel count reductions in portions of the scene not undergoing change within predetermined temporal criteria.

Abstract: This invention is directed to a wide dynamic range video imaging apparatus. More specifically, the invention is directed to a video imaging apparatus comprising a) a sensor for providing a plurality of video images of a scene at different exposure levels and b) a processor for processing the plurality of video images to produce a combined video image including image information from the plurality of video images by applying neighborhood transforms to the plurality of video images, the processor comprising a selector for locally selecting the operating levels of the dynamic range of the combined video image within the dynamic range of the sensor, whereby the resulting video image includes image information from the plurality of video images with enhanced information content at local areas therein.
