To recognize a specific pattern or a vehicle from image data photographed at a constant moving distance interval when an observation side and an object to be recognized are relatively moved.
An observation side at which a line sensor camera is set and an object including a specific pattern to be recognized are relatively moved in parallel, and when the object is photographed at a constant relative moving distance interval, the specific pattern is recognized from the time-sequential image data. In this case, the template of the specific pattern which is previously recorded in the line axial direction of the line sensor camera is enlarged and reduced, and the template is compared with the image data so that the similarity of the pattern can be calculated, and the specific pattern can be recognized from the image data by using the similarity of the pattern.
