PROBLEM TO BE SOLVED: To precisely detect a character rectangle which is possibly erroneous by judging the character rectangle whose character width is longer than character height based on the reliability of a recognized result, a noticed character and character information before and after it. ;SOLUTION: An image picture is inputted from a picture input part 101 and a character recognition processing part 104 executes a character recognition processing. A character re-segmenting judgement part 107 assumes the character whose character width is longer than character height as a contact character, and judges the re-segmenting to be necessary when a system applies to one of following three items. (1) The reliability of the noticed character by a reliability calculation part 106 is not more than a threshold, either character before or behind the noticed character is alphanumeric and the noticed character is not the alphanumeric. (2) Information of the part of speech on the noticed character is a non- registered word when the reliability of the noticed character is not more than the threshold, either character before or behind the noticed character is alphanumeric and the noticed character is also the alphanumeric. (3) The characters before and behind are not the non- registered words and the relations on the heights of the noticed character and the characters before and behind are the same.;COPYRIGHT: (C)1998,JPO
