ABSTRACT:
An object recognition or inspection system with special features is disclosed, in which an object to be inspected is photoimaged by a photo image sensing device. While forming a comparative control signal by processing the horizontal as well as vertical synchronizing signals contained in a complex video signal from the photo image sensing device, at the same time by supplying the video signal from the photo image sensing device and the reference signal from a reference signal generator, to a comparator, and by further supplying the comparative control signal to the comparator only during the period as specified by the comparative control signal, the video signal is compared with the reference signal at the comparator and an inspection start signal is generated from the comparator and then such inspection start signal is supplied to the inspection system to start the inspection of the object recognition system.
