The present invention provides a method for mending projection and recess defects existing on the surface of a metallic plate, wherein steps (1) to (2) are repeated until it is determined in step (1) that mending of the projection and recess defects on the surface of the metallic plate is no longer necessary. Step (1): A step for shining light onto the surface of the metallic plate, detecting the positions of projection and recess defects on the surface of the metallic plate according to the brightness distribution on the metallic plate, the brightness distribution being obtained from reflected light, quantifying the brightness intensities of the projection and recess defects, and determining whether it is necessary to mend the projection and recess defects. Step (2): A step for mending the projection and recess defects for which it is determined in step (1) that mending is necessary. |
