PROBLEM TO BE SOLVED: To solve the problems that erroneous detection of non-character patterns such as dirt or shade of equivalent size increases, it takes a long time for processing character detection and character recognition, recognition results more than those of actual case are output and reading precision of the whole character string is also lowered when reference conditions are widely set since a character pattern is detected on the basis of the size of characters in the conventional case. SOLUTION: The character pattern is segmented from an image of an image input means by a first character segmentation means by referring to format information of a character string for processing stored in a format information storage means, recognized by a first character recognition means and attributes of the recognized character pattern are determined by an attribute determination means. Character patterns around the character pattern are segmented by a second character segmentation means on the basis of position coordinates of the character pattern satisfying the predetermined conditions, the attributes of which are determined, recognized by a second character recognition means, recognition results to an input image are obtained from recognition results of the character patterns and output by the recognition result output means.
