Abstract
An optical character recognition apparatus is comprised of an original document reading out section for generating an original character signal corresponding to light and shade of an original document, a character slice section for sequentially generating a slice signal corresponding to one character from the original character signal, a character recognition section for recognizing a character corresponding to the slice character signal, and a display section for displaying a recognized character in correspondence to the original document, wherein when a correction target character is found from the displayed characters, the correction target character and characters around the correction target character are displayed on the display section by utilizing the original character signal. Therefore, the operator can efficiently correct the correction target character without consulting the original document, and also the operator can easily confirm by an image of that original document that a separate character or the like is erroneously recognized.
