Disclosed is a character recognition preprocessing method and apparatus for correcting a nonlinear character string into a linear character string. A binarized character string region is divided into character regions on a character-by-character basis. Upper and lower feature points of each character region are derived, and an upper boundary line, which is a curve connecting the upper feature points of the character regions, and a lower boundary line, which is a curve connecting the lower feature points of the character regions, are generated by applying cubic spline interpolation. Nonlinearity is corrected through adaptive region enlargement by using the maximum horizontal length and the maximum height of the divided character regions.

Disclosed is a method for retrieving a label in a portable terminal. The method includes obtaining a label image photographed through a camera, extracting characters included in the label image and recognizing the extracted characters, detecting at least one label including the recognized character from a label database including multiple labels and information on the multiple labels and constituting a preliminary label candidate group including said at least one label, detecting an image characteristic of the label image, detecting at least one label having an image characteristic, which is similar with the detected image characteristic, from the preliminary label candidate group, and constituting a final label candidate group, and providing each of said at least one label included in the final label candidate group and detailed information corresponding to each of said at least one label.
