Patent ID: 8144198

Claim:
An imaging system including detector means arranged to convert an image into electrical signals and processor means arranged to manipulate said signals for viewing on a display means, said detector means having plural pixels each with at least two sensitivity levels, said detector means being arranged to switch repetitively between the sensitivity levels, said processor means being arranged to select an appropriate sensitivity level from data collected for each pixel for display in dependence upon preset threshold criteria being met, said display means being arranged to display detected pixels that are processed with differing sensitivity levels at substantially the same time, a color adder arranged to convert data images from the detector means which are in a gray scale to color images, said processor means including integration and timing control means arranged to control the detector means sensitivity levels for each pixel and to switch sequentially between said levels, a plurality of store means arranged to store image data for present and previous images at respective sensitivities, combining means arranged to combine said stored image data into a combined data stream based on said threshold criteria being met, and output means arranged to output said combined data stream to said color adder.
