ABSTRACT:
A character string region extracting apparatus comprises an extracting section for extracting a plurality of primitives from image information in which a character and a graphic pattern other than the character are mixedly present, a character string candidate region forming section for generating character candidate regions from the primitives and connecting the character candidate regions, thereby forming at least one character string candidate region, a character recognizing section for subjecting the character candidate regions included in the character string candidate region to character recognition, and a character string region extracting section for extracting a character string region from the character string candidate region by the character recognition.
