Filed: 1989-05-26
Abstract: PURPOSE:To distinctly identify even a small abnormality from the other part by disposing the modulation signal corresponding to the position indicting the abnormality of an object to be inspected in superposition on the image signal of the object to be inspected. CONSTITUTION:A processing section 31 for an image signal receives the image signal V corresponding to the object 1 to be inspected from a TV camera 2 and inspects or processes this signal. The processing section outputs a good signal OK when the object 1 is non-defective according to the results thereof. A defective signal NG is outputted in correspondence to the position of the abnormality when the object is defective, i.e. when there is the abnormality, such as defect, in the object 1. The signals OK and NG are supplied to a modulating section 33. The modulating section 33 forms the modulation signal m in correspondence to the position of the abnormality and supplies this signal to a synthesizing section 32 only when the signal from the processing section 31 is the defective signal NG indicating the presence of the abnormality. The image V from the TV camera 2 is supplied as well to the synthesizing section 32. The distinct discrimination of even the small abnormality from the other part is possible in this way.
