Abstract

PURPOSE:To perform surface inspection of the object to be examined by video signal by defining one end of the inspection range of the image pickup unit with the edge of the object to be examined. CONSTITUTION:Restriction of the inspection range in the moving direction of steel plates is accomplished by an adder 21, memory 22, counter 23, set field extraction circuit 26, etc. When the reiterative image pickup of the surface of the steel plate by cameras TVCa thru TVCd is accomplished without extremes, Ls/No = B is set in the adder 21 and the signal S9 which becomes an arbitrary 1 field period 1 is outputted by the set field extraction circuit 26 and this is applied to an AND gate 24, through which steel plate speed pulses PGP are inputted to the adder 21.
