PURPOSE:To process pictures generated cyclically and at random by the same processing device by signals, which are subjected to first and second picture processings which extract features of one-picture components of first and second cameras, while shifting them from each other by a prescribed number of seconds and discriminating pictures. CONSTITUTION:Picture signals of industrial cameras 1a to 1c and 2a to 2c are supplied to first and second picture processing circuits 3 and 4, and the feature extraction processing of one-picture components is performed in 1/30 seconds. In circuits 3 and 4, picture signals are successively switched at intervals of 1/30 seconds by selecting circuits 31 and 41 and are converted by A/D converters 32 and 42, and the picture processing is performed by digital signal processing circuits 33 and 43. Thereafter, video signals are converted by D/A converters 34 and 44 to display one picture on a display device 6, and the output of the circuit 4 is shifted by 1/60 seconds in accordance with the output of the circuit 3 and is supplied to a computer 5 at intervals of 1/30 seconds. Thus, plural pictures generated cyclically and at random are quickly processed in the same processing device. |
