Abstract:
1. An imaging device, comprising a two-dimensional array of sensor elements which generates image data corresponding to a plurality of successive overlapping image frames; an A/D converter which converts the image data into digital image data corresponding to the plurality of successive overlapping image frames; a plurality of digital registers which store the digital image data received from the A/D converter; a plurality of digital adders which add values of the digital image data stored in the digital registers to image data stored in a digital memory, thus forming a single composite image frame obtained from the successive overlapping image frames, and storing the composite image frame in the digital memory, wherein each successive image frame is offset from an immediately preceding image frame by a spacing of not greater than a single pixel, such that each addition, by the digital adders of image data stored in the digital registers to image data stored in the digital memory adds a new single pixel line of data to the composite image frame.
