Abstract:
A image status detecting apparatus detecting whether or not a character image inputted through image input means is mirrored horizontally or vertically and/or detecting a rotation angle in 90 degree increments compared with an original character, said image status detecting apparatus comprising:image converting means for rotating in 90 degree increments and for mirroring the character image inputted through the image input means; character recognizing means for referencing a character recognition dictionary storing character feature information and for obtaining candidate characters resembling the character image mirrored and rotated by the image converting means and a recognition rate indicating a degree of recognition certainty; and conversion procedure detecting means for detecting, based on the candidate characters and the recognition rate obtained by the character recognizing means, a rotation angle in 90 degree increments and an existence of mirroring needed to direct the character image to a proper direction, based upon the recognition rate exceeding a predetermined value.
