Abstract:
1. An image processing device for processing a character rectangle extracted from an image, comprising: an acquiring unit configured to acquire a pixel block, which lies within the character rectangle in contact with an enclosing border of the character rectangle by scanning along the enclosing border, wherein a pixel block not in contact with the enclosing border is not acquired; a determination unit configured to determine whether or not the acquired pixel block has a likelihood of noise; a generating unit configured to generate a noise candidate removed character rectangle by removing from the character rectangle the pixel block when it is determined that the pixel block has the likelihood of noise; and an outputting unit configured to assess validities of both the noise candidate removed character rectangle and the character rectangle by performing character recognition, compare the two validities, and output a character recognition result based on the comparison result, wherein said outputting unit
