A system for creating component shape data for image processing to be used when performing image recognition of a component to be mounted by a component mounter including drawing a wire frame on top of the component image such that the wire frame surrounds a measurement target portion of the component image displayed on a display section; automatically aligning the position of the side of the wire frame to the edge position of the measurement target portion; and creating the component shape data for image processing by measuring the shape data of the measurement target portion surrounded by the wire frame for which the four sides of the wire frame were automatically aligned with the edge positions in four directions of the measurement target portion by the automatic aligning.
