Image data after the photoelectric conversion by the CCD 201 is read out and inputted to an A/D converter 202, to be converted into digital image data therein. In a shading correcting part 203, an offset adjustment at a black level and a shading correction at a white level including the characteristic of a lamp as well are executed. The image data after the correction is inputted to a mark sheet recognizing circuit 204. Then, a marking place on the mark sheet inserted by the mark sheet recognizing circuit 204 is confirmed and a specified function is displayed on the display part 219.
