VISION SYSTEM COMPRISING AN IMAGE SENSOR AND MEANS FOR ANALYSIS AND REDUCING LOSS OF ILLUMINATION TOWARDS PERIPHERY OF THE FIELD OF VIEW USING MULTIPLE FRAMES

摘要

A vision system is disclosed having an image sensor for capturing an image, the image sensor having a lens, an image processing unit and optionally a memory unit. The image processing unit is adapted to capture and/or store in the memory, for selected areas of the image, a set of frames from the past, where the division of the image in areas and/or the number of frames from the past depend on lens parameters, position and/or orientation of the image sensor, or image parameters of the captured image.
