Abstract:
The invention alleviates a burden on a user relating to an image inspection device based on photometric stereo and multi-spectral imaging. An illumination device  3  has three or more illumination blocks that irradiate a workpiece  2  with illumination beams from different directions, respectively. A camera  4  generates images of the workpiece  2 . An image processing device  5  irradiates the workpieces  2  sequentially with illumination beams from light emitting elements of different lighting colors and generates a plurality of spectral images. The image processing device  5  sequentially turns on the three or more illumination blocks in units of blocks and generates a plurality of direction images. The image processing device  5  generates a color inspection image based on the plurality of spectral images and executes color inspection. The image processing device  5  generates a shape inspection image based on the plurality of direction images and executes shape inspection.

Claim (Index 1):
An image inspection device comprising:\n an illumination unit which includes three or more illumination blocks that irradiate a target object with illumination beams from mutually different directions, each of the illumination blocks including a plurality of light emitting elements that generate the illumination beams having mutually different lighting colors; an imaging unit which receives light reflected from the target object illuminated by the illumination beams and generates an image of the target object; a control unit which controls the illumination unit to simultaneously turn on light emitting elements of an identical lighting color included in each of the three or more illumination blocks and to irradiate the target object sequentially with illumination beams while changing lighting colors and controls the imaging unit so as to generate a plurality of spectral images having mutually different lighting colors of the illumination beams, and controls the illumination unit to sequentially turn on light emitting elements of an identical lighting color included in each of the three or more illumination blocks and to irradiate the target object with illumination beams, and controls the imaging unit so as to generate a plurality of direction images having mutually different irradiation directions of illumination beams; an image generation unit which generates an inspection image based on the plurality of spectral images or the plurality of direction images; and an inspection unit which inspects the target object using the inspection image formed by the image generation unit, wherein a plurality of light emitting elements that output illumination beams of an identical lighting color are arranged at equal intervals in the illumination unit.
