Filed: 1997-02-10
Abstract: PROBLEM TO BE SOLVED: To recognize the direction of an original and to output image data in an appropriate direction. SOLUTION: For a segmented character image, the feature amount is extracted in a feature amount extraction circuit 540 and bisected into feature amount data depending on the direction of a character and feature amount piece number information not depending on the direction of the character.
