Abstract
A standard image of a product to be a standard for an inspection target is displayed, to set a first region so as to surround a standard pattern in the standard image. Further, a second region for characterizing a position and a posture of the standard pattern is set in the standard image. In a first search step, a feature extracted from the first region set in the standard image is searched from an inspection target image, to roughly obtain the position and the posture of the standard pattern in the inspection target image. In the second search step, the feature extracted from the second region set in the standard image is searched from the inspection target image, to minutely obtain at least one of the position and the posture of the standard pattern in the inspection target image.
