ABSTRACT:
A pattern information processing method is disclosed in which a video signal of an object from a television camera is divided at a plurality of different threshold levels, a clock pulse is gated with the divided video signals, the number of gated clock pulses by each of the divided video signals is counted, and a number of series is provided from the counted numbers of the clock pulses. This series is used to represent a pattern of the object.
Further, a pattern information processing apparatus is disclosed which has a television camera providing a video signal of an object, devices producing plural threshold levels different from one another, circuits dividing the video signal by the plurality of different threshold levels, circuits gating a clock pulse from a clock pulse generator by the divided video signals, and counters counting the numbers of the gated clock pulses to provide a number series which represents the object.
