PURPOSE:To perform arithmetic processing at high efficiency to judge fords by setting, for a subject for inspection, a plurality of processing areas outside and inside the contour of a form to be judged, and performing area comparison in the processing areas at the same time as sampling of images. CONSTITUTION:A subject for inspection, e.g. a label (character or diagram) undergoes form recognition by an image processing portion 3 including a pattern recognition portion using a CCD camera 2, and then undergoes checking using a pattern with the background of its form as a set value. For one kind of the form of the label character to be judged, a plurality of freely settable processing areas are stored by a data entry setting control portion 4 in window memory portions 5, 6 which are preset, respectively, outside and inside the contour of the form to be judged. Next, data converted into binary images by look-up tables 15,16 are compared with the memory portions 5,6 and stored in counters 17,18, and area comparison is performed in the plurality of processing areas at the same time as sampling of the images of the label, so as to determine in a short time whether or not the label is defective through multiple image processing that allows synthetic judgement. |
