PROBLEM TO BE SOLVED: To perform total inspection by automatizing conventional visual sampling inspection process. SOLUTION: A translucent mirror 8 is set between a blank 1 and a first CCD camera 5, and downward lighting 9 for irradiating a measuring object face is projected onto the translucent mirror 8, and an image picked up by the first CCD camera 5 is inputted into a computing device 10, and after an addition is carried out as the color brightness of every picture element is scanned in a direction parallel to the extending direction of each layer, a difference between data separated more than one of obtained added data is computed in order, and this device is equipped with an acceptance or rejection judging function which recognizes a dissociation peak as the boundary of a layer and judges whether a space between boundaries exists within a preset range or not. |
