Abstract
A multi-scanning system or image processing system includes a plurality of sensors, each of the sensors scanning a portion of the document to produce image data. Each of the sensors overlaps adjacent ones of the sensors so that the image data includes overlapped image data. The image data from the sensors is stitched together to form a complete image. The stitching may be performed by a weighted averaging of the data or by varying stitch location within the data. This stitching is useful in eliminating visible image defects created the misalignment of pixels between adjacent sensors.
