IMAGE PROCESSING METHOD, IMAGE PROCESSING APPARATUS, IMAGE FORMING APPARATUS, AND STORAGE MEDIUM
First Claim
1. An image processing apparatus, comprising:
- a division section for dividing input image data into a plurality of portions;
an orientation determining section for calculating reliabilities of upper-, lower-, left-, and right-directions of image data of each of the plurality of portions when the upper-, lower-, left-, and right-directions are regarded as orientations, and setting an orientation with the highest reliability out of the calculated reliabilities as an orientation of said each of the plurality of portions;
a display control section for, when the plurality of portions whose orientations are set by the orientation determining section include a target portion whose reliability of an orientation is less than a predetermined value and a non-target portion whose reliability of an orientation is not less than the predetermined value, generating display image data used when a display device displays at least an image of the target portion and images of designation regions by one of which a user'"'"'s input to designate the orientation of the target portion is entered; and
a character recognition section for recognizing characters of the plurality portions in such a manner that the orientation of the target portion is an orientation designated from one of the designation regions and the orientation of the non-target portion is an orientation set by the orientation determining section.

Abstract
An image processing apparatus includes: a division section for dividing input image data into portions; an orientation determining section for calculating reliabilities of directions of image data of each portion when the directions are regarded as orientations, and setting an orientation with the highest reliability as an orientation of each portion; a display control section for generating display image data including an image of a target portion whose reliability of an orientation is less than a predetermined value and images of designation regions from which a user'"'"'s input to designate the orientation of the target portion is entered; and a character recognition section for recognizing characters of each portion in such a manner that the orientation is designated from the designation regions or set by the orientation determining section. This allows prompt recognition of characters of a portion whose reliability of orientation is low, in accordance with a right orientation.

10. An image processing method, comprising the steps of:
-
(i) dividing input image data into a plurality of portions; (ii) calculating reliabilities of upper-, lower-, left-, and right-directions of image data of each of the plurality of portions when the upper-, lower-, left-, and right-directions are regarded as orientations, and setting an orientation with the highest reliability out of the calculated reliabilities as an orientation of said each of the plurality of portions; (iii) when the plurality of portions whose orientations are set in the step (ii) include a target portion whose reliability of an orientation is less than a predetermined value and a non-target portion whose reliability of an orientation is not less than the predetermined value, generating display image data used when a display device displays at least an image of the target portion and images of designation regions by one of which a user'"'"'s input to designate the orientation of the target portion is entered; and (iv) recognizing characters of the plurality portions in such a manner that the orientation of the target portion is an orientation designated from one of the designation regions and the orientation of the non-target portion is an orientation set in the step (ii).
