Claim:
1. A read image processing apparatus for processing a read image read by a reading part including a plurality of line image sensors, each of the line image sensors including reading elements arranged in line corresponding to pixels, the line image sensors being arranged in such a manner that one end parts of the line image sensors adjacent to each other are overlapped with each other in a direction perpendicular to a direction of alignment of the reading elements, comprising: a density variation detector to detect whether a density variation occurs for not less than a predetermined number of times or not in each of a plurality of regions in a seam-read image, the seam-read image being an image read by the reading elements present within a seam portion in which the line image sensors adjacent to each other are overlapped with each other; a seam processor to generate a seam image by synthesizing the seam-read images read by the line image sensors adjacent to each other in accordance with a detection result made by the density variation detector, the seam image being an image of the seam portion; and a line image generator to generate a read image corresponding to one line based on read images read by the line image sensors and the seam image generated by the seam processor.
