Abstract

An inspection device for inspecting an inspection object portion in a PTP sheet, the inspection device including: an irradiator that irradiates the inspection object portion with light; an imaging device that takes an image of the inspection object portion irradiated with the light; a processor that detects a defect in the inspection object portion from the taken image by using a predetermined luminance threshold value, and determines whether the inspection object portion is non-defective; a verification image generating circuit that generates a verification image in which a virtual defective image is placed in a non-defective image; and a threshold value verifier that causes the processor to determine whether the inspection object portion is non-defective or defective by using the verification image, in place of the image taken by the imaging device, and to verify the luminance threshold value based on a determination result by the processor.
