An image input apparatus receives image data from a scanner having a reading surface on which an original image is placed, the image data being generated through reading the reading surface. An image outline determination apparatus determines an outline of an original image placed on the reading surface of the scanner in accordance with the image data obtained by the scanner. An area designation section designates a rectangular proposed area of which at least portion enters into an area of the original image placed on the reading surface. An outline determination section determines the outline of the original image by repeating a plurality of number of times an area alteration processing in which a movement of sides defining an outline of the proposed area outside or inside the proposed area is determined in accordance with differential or difference of image data for vicinity of the sides, and the proposed area is altered in accordance with a decision of the movement, wherein the area alteration processing is repeated taking an area after the proposed area is altered as a new proposed area.
