In reading of the original by a plurality of image pickup elements, the image is read by the image pickup elements covering overlapping image regions. Among those located within the overlapping portions, a pixel having small density change values with respect to adjacent pixels is detected and specified as a switching pixel. The image pickup signals read by the image pickup elements are connected at the switching pixels, thereby to obtain a reproduced image.
