Abstract: The present invention provides a character recognition method and recording medium for recognizing characters entered in a document or the like including preprint information. An object of the invention is to recognize characters in contact with or superposed on the preprint information without using any knowledge of the preprint information or a difference in gray level. An image in an area where the characters to be recognized are present is divided into line segments individually, wherein the image is obtained by reading the preprint information and the entry characters. A recognition image is created by changing a combination of the plurality of line segments divided. A recognition result with the reliability is memorized by making the character recognition for the created recognition image. And the recognition result having a greatest reliability is output by executing the character recognition for all the combinations while changing the combination of line segments successively.

Abstract: A character pattern is extracted from image data read from a document, listing, etc., and discriminated between a hand-written character and a typed character by a hand-written/typed character discrimination unit. The hand-written/typed character discrimination unit obtains, from the character pattern, N feature vectors containing a feature indicating at least the complexity and the linearity of the character pattern; and discriminating the character pattern between a hand-written character and a typed character using the feature vectors. A character recognition unit performs a character recognizing process based on the result of discriminating whether the character data is a hand-written character or a typed character. As a feature of the above described character pattern, the variance of line widths, the variance of character positions, etc. can also be used.
