An automatically generating program and device are provided which can easily and accurately create an operation program with no need of providing an image data input device. The program, causes a work head to move relative to a work object and to carry out desired work, includes the steps of displaying a reference data input window which allows input of shape data of the work object or a work region (STEP 201), taking in image data of the work object or the work region (STEP 202), compensating for distortion in the taken-in image data (STEP 203), displaying a movement path input window which allows designation of a movement path with the compensated image data displayed as a background (STEP 204), and automatically generating the operation program based on the movement path that is designated on the movement path input window (STEP 205).
