An illumination apparatus has a plurality of LEDs arranged in a substantially annular form, a light diffusion member for diffusing light emitted from the plurality of LEDs, and a lighting control part for lighting the plurality of light sources in accordance with a predetermined lighting pattern when designated to start lighting. In particular, the illumination apparatus moves independently of a camera to adjust a distance to a workpiece.
