Abstract
In a character recognition apparatus, the determination processing of whether or not there exists a character line in a segment region is divided into two processes. The initial confirmation process determines the existence or nonexistence of a character line in a segment region having a first size using first determination means. The second confirmation process determines the existence of a character line in a segment region having a second size which is larger than the first size using second determination means. Hence, a noise image is determined to have no character line at a stage in which the segment region has been set to the second size, and a correct character recognition operation is therefore performed. Furthermore, when there is a plane image within the first region, it is determined that there is no character line at a stage in which the small segment region having the first size has been set. Hence, it is possible to shorten the time for the recognition processing.
