PROBLEM TO BE SOLVED: To reduce the degradation of image quality when the trigger of each line has a timing deviation, in an image processing device forming an image by the two-dimensional scanning of a laser.SOLUTION: In an image generation device for generating the image of an object to be inspected from a pixel group obtained by reciprocatively scanning the object to be inspected in a main scanning direction with the laser, pixel line acquisition means for acquiring a first pixel line from one reciprocation scanning with the laser and a second pixel line adjacent to the first pixel line and from one reciprocation scanning with the laser and reciprocation comparison means for comparing the first pixel line and the second pixel line and detecting a positional deviation amount between the first pixel line and the second pixel line are arranged.SELECTED DRAWING: Figure 2 |
