A method and apparatus are disclosed for compensating for assembly and alignment errors in multi-segment sensor assemblies. The placement of each sensor segment is characterized by the coordinates of its end pixels in scanner pixel space. For each pixel in each segment, an offset is computed, using the segment's slope and first pixel location, indicating the number of scan lines the pixel should be shifted to place its data in the image pixel nearest its ideal location. During scanning of an image, image data is placed in a buffer. Upon placement in the buffer or placement into a final output destination, image data from each interval of the segment is shifted by a distance in the subscanning direction that minimizes image artifacts. In an alternative embodiment, interpolation is performed between two adjacent scan lines. The data from two overlapping segments may optionally be smoothed by combining data from redundant pixels.
