Abstract

PURPOSE:To always keep constant the way of the image splitting even in case the test subject may move continuously to the camera, by dividing the inner side of the test subject into several regions of inspection based on the fringe of the image of the test subject. CONSTITUTION:The video signal Sa obtained through the TV camera is applied to the deciding circuits 501-509 provided in correspondence to the region of inspection, and the detection signals Sy1-Sy9showing the defective area of each region of inspection are obtained. On the other hand, the signal Sa and the horizontal synchronous signal are applied to the image fringe part detecting circuit to obtain the image fringe signal. And from this fringe signal, the signal having the time duration equivalent to the horizontal width of the region of inspection plus the signal entering the inner side of the region are obtained. And the n units of horizontal split signals are obtained from the both signals mentioned above. At the same time, the vertical synchronous signal is applied to the vertical dividing circuit to obtaine m units of vertical split region signals. These horizontal and vertical split region signals are applied to nXm units of AND circuits to obtain the test region signals alpha1-alpha9. These signals are then applied to the AND circuits 901-909 to obtaind the detection signals Sy1'-Sy9'.
