Abstract: A technical solution is provided, which allows generating a high-quality digital image using multiple CCD arrays. More specifically, a lens generates an image on an area equal to the sum of photosensitive areas of n CCD arrays. The CCD arrays are shifted from one another. The image is projected via four channels onto all the CCD arrays such that each of said arrays generates a video signal from only one of n sectors of the image. The video signals from the CCD arrays, which operate on a conventional scanning standard and in parallel, are digitized, pre-processed and recorded in a memory from which they are read at a rate n times higher than a clock rate. A digital image is produced by electronically combining the video signals from the CCD arrays that convert adjacent sectors of the image, after which the video signal is post-processed.
