PURPOSE:To sharply reduce the amount of image data to be filed in a comparative image inspection apparatus in which the abnormality of image data is detected by comparing data images. CONSTITUTION:Reference image data which is constituted of (n) bits and inspected image data are inputted to a coincidence and disagreement detection means 2. When no disagreement exists in both data, a prescribed signal from the coincidence and disagreement detection means 2 is outputted as a Lo signal. Only the reference image data is inputted to a reference-image-data standardization means 3 and it is shaped as store data and preserved in a preservation means 4. When the reference image data does not coincide with the inspected image data, the prescribed signal from the coincidence and disagreement detection means 2 becomes a Hi signal. The inspected image data at this time is input to an inspected-image-data standardization means 3a, and it is shaped as store data and preserved in the preservation means 4 simultaneously with the reference image data. Thereby, a part, of the inspected image data, which does not coincide with the reference image data is filed. |
