Abstract
PURPOSE: To improve remarkably the precision of character recognition by making a decision on the kind of a current character to be recognized by referring to the physical relations between the current recognized character and preceding and following recognized characters.
CONSTITUTION: A digitized video signal in video memory 7 is supplied to segmenting circuit 8, which generates a quadrilateral circumscribing a character, and its output is stored in memory 12 by way of recognizing circuit 9, character height extracting circuit 10 and character width extracting circuit 11. In memory 12, proposed characters, and character height and character width data are stored being classified by characters to be recognized. Mutual character feature extracting circuit 13 finds the mean value of the character width by the character width data and also finds the mean value of the character height by the character height data to send those mean values to answer editing circuit 14. Assuming that there are proposed charadters, "katakana" (square form of Japanese syllabary ""ro"(Japanese:katakana,256D)" and "handakuten" (make for "p"-sound) "°", circuit 14 selects "katakana "ro"(Japanese:katakana,256D)" when the size of the character is nearly equal to the mean value or "handakuten °" when nearly 1/3 as much as the mean value.
