Abstract
A large-size (A3-size) original is folded into two small-size (A4-size) portions. Images on the surfaces of the respective portions are read by image reading units. Image data output from the image reading units are stored in a memory. A detection unit detects end positions of the read images, and skew of each of the images is corrected. An image synthesis unit synthesizes the image data of the respective surfaces based on the output of the detection unit to provide the original single image. Thus, it is possible to read even a large-size original.
