Abstract

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.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 120 words
A pattern information processing method comprising the steps of: (a) picking up an object by scanning with an image sensor to produce a video signal corresponding to said object; (b) dividing said video signal by a plurality of threshold levels which are different from one another; (c) gating clock pulse trains with said divided video signals to produce clock pulse trains corresponding to said plurality of threshold levels; (d) counting said clock pulse trains to provide a number series which represents a pattern of said scanned object; and (e) modulating said clock pulse train during said scanning whereby a number of said clock pulses counted in at least two different equal portions of said video signal differ from each other.
Claim 2
Dependent Claim 120 words
A pattern information processing method comprising the steps of: (a) picking up an object by scanning with an image sensor to produce a video signal corresponding to said object; (b) dividing said video signal by a plurality of threshold levels which are different from one another; (c) gating clock pulse trains with said divided video signals to produce clock pulse trains corresponding to said plurality of threshold levels; (d) counting said clock pulse trains to provide a number series which represents a pattern of said scanned object; and (e) modulating said clock pulse train during said scanning whereby a number of said clock pulses counted in at least two different equal portions of said video signal differ from each other.
Claim 3
Dependent Claim 21 words
A pattern information processing method as claimed in claim 1, in which said modulating includes frequency modulating said clock pulse trains.
Claim 4
Dependent Claim 145 words
A pattern information processing apparatus comprising: (a) image sensor means for scanning an object to produce a video signal of said object; (b) means for providing a plurality of threshold levels which are different from one another; (c) means for dividing said video signal by said plurality of threshold levels to produce gate signals corresponding to said video signals divided by said plurality of threshold levels; (d) means for producing a clock pulse signal; (e) AND-means for separately gating said clock pulse signal by each of said gate signals; (f) means for counting said clock pulse signals from said AND-means and providing a number series which represents the scanned object; and (g) means for modulating said clock pulse signal during said scanning whereby a number of said clock pulses counted in at least two different equal portions of said video signal differ from each other.
Claim 5
Dependent Claim 145 words
A pattern information processing apparatus comprising: (a) image sensor means for scanning an object to produce a video signal of said object; (b) means for providing a plurality of threshold levels which are different from one another; (c) means for dividing said video signal by said plurality of threshold levels to produce gate signals corresponding to said video signals divided by said plurality of threshold levels; (d) means for producing a clock pulse signal; (e) AND-means for separately gating said clock pulse signal by each of said gate signals; (f) means for counting said clock pulse signals from said AND-means and providing a number series which represents the scanned object; and (g) means for modulating said clock pulse signal during said scanning whereby a number of said clock pulses counted in at least two different equal portions of said video signal differ from each other.
Claim 6
Dependent Claim 20 words
A pattern information processing apparatus as claimed in claim 3, in which said means for modulating is a frequency modulator.
