CHARACTER RECOGNITION METHOD AND DEVICE THEREFOR

摘要

PROBLEM TO BE SOLVED: To make precisely detectable a character frame position and to make recognizable a character filled in a character frame even if the character frame in image data is thinned or a background printing exists around the character frame by detecting the position of the character frame based on a frame area direction code obtained in the detection area of the character frame. SOLUTION: An area detecting a character frame is decided from document image data stored in an image data storage part 12 and character registration data containing a frame coordinate value stored in a character frame registration data storage part 13. A frame area direction code is detected with an object where black picture elements in the frame detection area are connected as an outline trace. The corner position candidate coordinate of the character frame is detected and is stored in a frame corner candidate coordinate storage part 18 against a picture where a candidate frame line generated based on a frame line candidate position is written. The position of a character frame inner-side is decided from the corner position candidate coordinate of the character frame stored in the frame corner candidate coordinate storage part 18 and character frame registration data stored in the character frame registration data storage part 13.
