Abstract

PURPOSE:To rapidly perform character recognition, by generating the circumscribing frame of a character image segmented from read image data, and extracting a coordinate system representing a distance from the circumscribing frame to a character contour as an unknown character pattern representing the outer shape of an unknown character. CONSTITUTION:The titled device includes an image pickup means, a character detecting part, and a character recognition part, and the character detecting part includes an image binarization means, a character detecting and segmenting means, and a normalization means. And the character recognition part includes an outer shape extraction means which generates the circumscribing frame of the character from the normalized character image data and extracts the coordinate system representing the distance from the circumscribing frame to the character contour as the character pattern representing the outer shape of the unknown character, a distance difference arithmetic means which computes the weighed means value of the difference between a reference pattern memory and the distance from the circumscribing frame to the character contour, and a character kind decision means. In such a way, it is possible to recognize the character whole line width fluctuates as a whole or partially, the character whose contour shape is formed unsmoothly and irregularly, and a marking character on a coated plane especially accurately and rapidly.
