Image data processor

Claim 2

An image data processor comprising: first means (1 and 2) for converting an image including an object to be recognized into spacially quantitized picture element signals; second means (3) for extracting plural pairs of the picture element signals, which are in spacially preset relative position relationships, from the output of the first-named means while sequentially shifting the picture element positions to be extracted; third means (4) connected with the second-named means for counting the number of occurences of preset amplitude relationships between the plural pairs of the input signals when the output signals from the second-named means indicate the picture elements which are included in a preset region of the image; fourth means (7) for dividing a reference image into a plurality of regions to store in advance the feature data of each of the divided regions; and fifth means (8) for sequencially comparing the counted data generated from the third-named means and those data of the fourth-named means, which correspond to said preset regions, whereby the object in the image is recognized from the compared results of the fifth-named means.

Claim 3

An image data processor comprising: first means (1 and 2) for converting an image including an object to be recognized into spacially quantitized picture element signals; second means (3) for extracting plural pairs of the picture element signals, which are in spacially preset relative position relationships, from the output of the first-named means while sequentially shifting the picture element positions to be extracted; third means (4) connected with the second-named means for counting the number of occurences of preset amplitude relationships between the plural pairs of the input signals when the output signals from the second-named means indicate the picture elements which are included in a preset region of the image; linear transformation means (6) for converting the relationships between the counted data generated from the third-named means and the paired picture elements corresponding thereto into one-dimentional data; fourth means (7) for dividing a reference image into a plurality of regions to store in advance the feature data of each of the divided regions; and fifth means (8) for sequentially comparing the data generated from said linear transformation means and those data of the fourth-named means, which correspond to said preset regions, whereby the object in the image is recognized from the compared results of the fifth-named means.

Claim 4

An image data processor comprising: first means (1 and 2) for converting an image including an object to be recognized into spacially quantitized picture element signals; second means (3) for extracting plural pairs of the picture element signals, which are in spacially preset relative position relationships, from the output of the first-named means while sequentially shifting the picture element positions to be extracted; third means (4) connected with the second-named means for counting the number of occurences of preset amplitude relationships between the plural pairs of the input signals when the output signals from the second-named means indicate the picture elements which are included in a preset region of the image; linear transformation means (6) for converting the relationships between the counted data generated from the third-named means and the paired picture elements corresponding thereto into one-dimentional data; fourth means (7) for dividing a reference image into a plurality of regions to store in advance the feature data of each of the divided regions; and fifth means (8) for sequentially comparing the data generated from said linear transformation means and those data of the fourth-named means, which correspond to said preset regions, whereby the object in the image is recognized from the compared results of the fifth-named means.

Claim 5

An image data processor as set forth in claim 1 or 2, wherein the third-named means includes: a plurality of comparators made receptive of a pair of the picture element signals from the second-named means for generating signals when a preset amplitude relationship resides among the input signals; a plurality of counters provided for said comparators, respectively, for accomplishing their counting operations in accordance with the output signals of said comparators, respectively; and means for presetting the operating periods of said counters, respectively.
