IMAGE PROCESSING METHOD, IMAGE PROCESSOR AND BONDING DEVICE

摘要

PURPOSE: To highly accurately detect a position without performing pattern matching in a rotating direction even in the case that a detection object is arranged in a posture including a position deviation in the rotating direction and to efficiently execute the generation of a mask pattern. CONSTITUTION: Inter-image subtraction is performed between a detection object image and a template image decided by a reticule mark 42 and a mark pattern image is generated/stored by utilizing the result (area hatched). In runtime, the area corresponding to the mask pattern image is excluded from the object of pattern matching.
