摘要:
A character recognition apparatus generates each character candidate from a character string written in a plurality of character entry boxes written on a sheet of paper such as a business form, and performs character recognition. A row image separating unit acquires an image containing a plurality of character entry boxes and the character string. A character extraction processing unit detects each point at which a plurality of lines are in contact with each other and intersect in the character string contained in the image, determines a point at which the character string should be cut or recombined on the basis of the placement relationship between the point and the corresponding character entry box, and generates each character candidate constituting the character string. A character recognition unit performs character recognition for each character candidate generated by the character extraction processing unit.
