An image processing apparatus comprising:

• an original supporting table for supporting an original, said original having an information portion and a non-information portion;
• reading means for reading an area of the table including and area on which the original is placed and for generating image data corresponding to the read area;
• first detector means for detecting the position or size of the original on said table based on image data from said reading means;
• second detector means for detecting the position or size of the information portion of said original based on image data from said reading means;
• and
• process means for processing image data from said reading means based on either the result of the detection by said first detector means or the result of the detection by said second detector means.
