PURPOSE:To make the results of inspection match visual judgment by a method wherein a binary-coded image stored is scanned from a specified direction to determine a changing point from a non-symbol image to a symbol image and the symbol image at the changing point is altered to the non-symbol image to remove effect by the seepage of ink. CONSTITUTION:A character, mark and the like to be detected are taken with a camera 1 and binary coded with an A/D converter of a binary coding processing section 2a to be stored into an image memory 2c of an image memory block 11. An image stored in the memory 2e is taken in to be scanned downward to the right from the left and pixels of black are turned to white at the changing point where the pixels of the image change to the black from white to be stored into an image memory 2f. The same operation is repeated and the image is scanned downward from the right to the left and downward to be stored into a memory 2g, from the top to the bottom and from the left to the right to be stored into a memory 2h and from the bottom to the top and from the left to the right to be stored into a memory 2i. An image data stored is rearranged in a fine line by ANDing computation for each pixel and is stored into an image memory 2j after the removal of the effect by the seepage of ink. |
