Abstract: An optical measuring device comprises: a lens to form an image with reflected light from a measuring object; an image sensor to receive the reflected light that has passed through the lens and generate an image representing the measuring object; a driver to drive a drive object, the drive object being at least one of the lens and the image sensor; and a controller to control the optical measuring device. The controller acquires, from the image sensor, a plurality of images generated by the image sensor successively imaging the measuring object while the driver is driving the drive object in accordance with a predetermined driving pattern, and outputs the plurality of images.
