ABSTRACT:
An image processing apparatus capable of detecting (1) the size or position of the original on the table, and/or (2) the size or position of an information portion of the original. The apparatus includes an original supporting table for supporting an original. The original has an information portion and a non-information portion. Reading apparatus is provided for reading an area of the table including the original placed on the table, and for generating image data corresponding to the read area and the read original. First detector circuitry is included for detecting the position or size of the original on the table based on the image data from the reading apparatus. Second detector circuitry is included for detecting the position or the size of the information portion of the original based on the image data from the reading apparatus.
