Claims

[Scope of utility model registration request]

A-- which processes the imaging object and the image signal from it.
In an inspection device that inspects an object, it has an image signal processing device having a D converter, a feature extraction circuit, a computer, etc. A calibration body that serves as a reference for the inspection conditions is placed in a position that does not interfere and remains unchanged throughout the inspection, and the calibration body and the standard body or the object to be inspected are simultaneously imaged by the image pickup body, and the image from the image pickup body is A signal is supplied to a calibration signal forming circuit, which detects a signal corresponding to the calibration object among the image signals, and the detection signal and the image signal are supplied to a correction circuit, where the image from the imaging object is detected. An inspection device characterized in that a signal is corrected using the detection signal.
