  • Patent number: 10417757
    Abstract: An image inspection apparatus is provided with an image sensing unit, a determination unit, and a reference image generation unit. The image sensing unit captures an inspection target. The determination unit takes a difference between a reference image that includes a solid image of the inspection target and a captured image that is captured of the inspection target. The determination unit thereby extracts an image that is not included in an image of the inspection target in the reference image, and determines the quality of the inspection target based on the extracted image. The reference image generation unit generates the reference image that is used by the determination unit by performing predetermined image processing to change to an image showing the inspection target that is included in the captured image into a solid image.
