PURPOSE:To easily discriminate the legality/illegality of image data by calculating the total number of prescribed pixel values and/or the pixel value on a prescribed position by a pixel calculating part, displaying the calculated number and comparing the displayed number with values stored in a respective storage parts. CONSTITUTION:A slit 10 is converted into image data by an image data reading part 20 and stored in an image data storing part 31 and the total number of prescribed pixel values and/or the pixel value on the prescribed position is calculated by the prescribed pixel calculating part 60 and stored in a prescribed pixel value total storing part 41 and/or a prescribed pixel value storing part 51. At the processing of the image data, at least one of the total number of prescribed pixel values and the prescribed position pixel value is referred to decide the legality/illegality of the image data. At the display of the image data, the image data are taken out from he storage part 31 and displayed on an image display device 110 by a image display part 80 and the total number of prescribed pixel values and/or the pixel value on the prescribed position is calculated by the calculating part 60 and compared with the values of respective storage parts 41, 51 after display operation to determine the ligality/illegality of the image data. |
