Abstract
When color image information including silver image information is photoelectrically read, the deterioration of image quality caused by a silver image is corrected to thereby obtain a high-quality image. In an image reading apparatus 100 for reading an image on a color silver salt photosensitive material in which silver halide and/or developing silver remains, there are provided: a CCD 113 for photoelectrically reading the image on the photosensitive material F in accordance with the spectral sensitivity of the photosensitive material F; and a color correcting portion 121 for correcting the deterioration of image quality caused by silver halide and/or developing silver for each of the color outputs of the CCD 113.
