INSPECTION DEVICE, IMAGE DISCRIMINATING DEVICE, DISCRIMINATING DEVICE, INSPECTION METHOD, AND INSPECTION PROGRAM

摘要

The reliability of determination in which a discriminator is used is prevented from being impaired even when the discrimination performance of the discriminator deteriorates due to re-learning or additional learning. An inspection device pertaining to one aspect of the present invention holds both of a first discriminator before re-learning or additional learning, and a second discriminator after re-learning or additional learning. The numeric range of a second criterion of the second discriminator is set to be narrower than the numeric range of a first criterion of the first discriminator. When a second output value of the second discriminator satisfies the second criterion, the inspection device determines the acceptability of a product on the basis of the second output value of the second discriminator. However, when the second output value of the second discriminator does not satisfy the second criterion, the inspection device determines the acceptability of the product on the basis of a first output value of the first discriminator.
