In order to measure a measurement object, a user generally operates a gauge, that is, a cursor using an input device such as a touch panel, a trackball, or a mouse for inputting coordinates, and sets a measurement point, a region of interest, and the like on a display image. In this way, when a user performs a manual operation, various attempts to automate the operation have been made because the experience, skill, and the like of the user have an influence.
