ABSTRACT:
An fixed form image reading apparatus includes an imaging portion for taking an image of a fixed form image formed in accordance with a predetermined rule so as to deliver image data, a luminance detecting portion that detects an accumulated value of luminance of a plurality of predetermined areas in the fixed form image as reference luminance data, an interpolation coefficient generating portion that generates an interpolation coefficient for performing interpolation so that luminance of the image data of the fixed form image becomes a predetermined level by using the reference luminance data, and a luminance correcting portion that corrects luminance of the image data of the fixed form image based on the interpolation coefficient.
