Claims Analysis
Total Claims: 3
Claim 1
Independent Claim
77 words
Apparatus employing line scanning for counting individual features in which a two state signal derived from the video signal from each line scan is delayed by delay means and compared with a two state signal derived from the video signal from the next line scan for controlling the generation of a count pulse for each feature, the improvement wherein; said signal delay means for delaying the two state signal from line to line comprises a shift register.
Claim 2
Dependent Claim
77 words
Apparatus employing line scanning for counting individual features in which a two state signal derived from the video signal from each line scan is delayed by delay means and compared with a two state signal derived from the video signal from the next line scan for controlling the generation of a count pulse for each feature, the improvement wherein; said signal delay means for delaying the two state signal from line to line comprises a shift register.
Claim 3
Dependent Claim
72 words
Apparatus as set forth in claim 1 further comprising computer means for generating a binary type electrical information signal whose value is representative of a parameter of a feature during scanning thereof, memory means comprising a shift register for retaining the information signal from line to line and gating means operable on release of said count pulse for the feature to release the information signals stored in the memory means relating thereto.
