Abstract
Abstract A pattern segmenting system for a pattern recognizing device, including a pattern memory for storing character information, means for reading out the character information from the pattern memory, means for detecting the start and end points of a subpattern in the character information and for calculating the center of the subpattern in accordance with the start and end points thereof, means for deciding whether or not the center thereof is within a selected character frame, and means for segmenting the subpattern when the center thereof is within the selected character frame and for regarding the frame as a blank when it is not within the selected character frame.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
158 words
A pattern segmenting system comprising: a memory for storing at least one information pattern; first means for reading out the information pattern from said memory; second means for detecting the start and end positions of at least one subpattern in the information pattern read out from said first means; third means for calculating the center position of the subpattern in accordance with the start and end positions detected by said second means; fourth means for storing the end position of a selected pattern frame; fifth means for detecting whether or not the center position of the subpattern is within the selected pattern frame by comparing said center position with said end position of said selected pattern frame; and sixth means for segmenting the subpattern only when the center position of the subpattern is within the selected pattern frame and for regarding the frame as blank when the center position of the subpattern is outside the selected pattern frame.
Claim 2
Dependent Claim
158 words
A pattern segmenting system comprising: a memory for storing at least one information pattern; first means for reading out the information pattern from said memory; second means for detecting the start and end positions of at least one subpattern in the information pattern read out from said first means; third means for calculating the center position of the subpattern in accordance with the start and end positions detected by said second means; fourth means for storing the end position of a selected pattern frame; fifth means for detecting whether or not the center position of the subpattern is within the selected pattern frame by comparing said center position with said end position of said selected pattern frame; and sixth means for segmenting the subpattern only when the center position of the subpattern is within the selected pattern frame and for regarding the frame as blank when the center position of the subpattern is outside the selected pattern frame.
Claim 3
Dependent Claim
24 words
A pattern segmenting system according to claim 1, which further includes a second memory for storing the information pattern segmented by said sixth means.
Claim 4
Dependent Claim
43 words
A pattern segmenting system according to claim 2, which further includes eighth means for storing the information pattern in said second memory so that the center of the information pattern coincides with the center of a predetermined storage area in said second memory.
Claim 5
Dependent Claim
49 words
A pattern segmenting system according to claim 1, which further includes seventh means responsive to said second means for calculating the size of the subpattern and for regarding the subpattern as a noise when the size of the subpattern in the information pattern is smaller than a predetermined value.
Claim 6
Dependent Claim
55 words
A pattern segmenting system according to claim 1, which further includes eighth means for indicating whether or not the information pattern in the selected pattern frame includes a plurality of subpatterns, and in which said sixth means includes means responsive to said eighth means for segmenting the information pattern except for the last subpattern thereof.
Claim 7
Dependent Claim
59 words
A pattern segmenting system according to claim 1, which further includes eighth means for detecting that the width of the subpattern is more than a predetermined value, and in which said sixth means has means for segmenting the subpattern separated at a predetermined position as the information pattern in the selected pattern frame in response to said eighth means.
Claim 8
Dependent Claim
41 words
A pattern segmenting system according to claim 1, wherein said sixth means includes means for segmenting the subpattern in the pattern frame subsequent to said selected pattern frame when the center position of the subpattern is outside the selected pattern frame.
Claim 9
Dependent Claim
71 words
A pattern segmenting system according to claim 1, which further includes eighth means for indicating whether or not the information pattern in the selected pattern frame includes a plurality of subpatterns, and in which said sixth means includes means for segmenting the plural subpatterns indicated by said eighth means as the information pattern in the selected pattern frame when the centers of the plural subpatterns are within the selected pattern frame.
