Title:
CHARACTER RECOGNIZING DEVICE
Document Type and Number:
Japanese Patent JP3236732
Kind Code:
B2
Abstract:

PURPOSE: To provide a character recognizing device which can fast and accurately segment and recognize the characters and also can detect the margins regardless of a document printed in mixed full and half size characters or a document of unfixed pitches.
CONSTITUTION: A character string extracting part 2 segments an input character string image, and a character element detecting part 3 extracts the character elements. A character width calculating part 4 calculates the widths of full and half size characters based on the height, etc., of the character images. A character element dividing part 5 detects and divides the character elements of widths less than the half size character width. A character candidate generating part 6 connects together the divided character elements to generate the full and half size character candidate images, and these candidate images are tentatively recognized by a recognizing part 7. The result of this recognition is evaluated again by a recognition result evaluating part 8. Thus the correct characters are recognized. Then a margin adding part 9 decides the presence or absence of inter-character margins based on the calculated character pitch.
