Abstract

An image reading device includes a light source for illuminating an image in a developed photo film by applying illuminating light thereto. An area CCD reads the image by photoelectrically detecting the illuminating light reflected by, or transmitted through, the developed photo film, to obtain image data respectively of pixels. An input unit inputs information of a photo film type, printing size or printing magnification. A determiner determines whether the photo film type, printing size or printing magnification satisfies a predetermined data correcting condition related to image data correction. An image processor extracts a group of inappropriate pixels from the pixels by checking the image data if the photo film type, printing size or printing magnification satisfies the data correcting condition, and corrects the image data of the inappropriate pixel group.
