摘要： The present invention relates to an image-centering method, and more particularly, to an image centering method comprising: a registration step of registering an inspection subject as a model image by photographing the inspection subject with an optical system with a first magnifying power and setting a position of an inspection region to be searched in a photographed image of the first magnifying power; a photographing step of photographing the inspection subject with an optical system with a second magnifying power higher than the first magnifying power according to a predetermined order to obtain a target image; a reduction step of reducing the target image obtained from the photographing step to the size of that of image of the first magnifying power to register the target image as an inspection image; a matching step of searching for the inspection image in the model image; and, when the inspection image is found through the matching step, a centering step of moving the optical system with the second magnifying power or the inspection subject to correspond to the position of the inspection region set in the registration step.
