Filed: 1996-10-08
Abstract: PROBLEM TO BE SOLVED: To improve the recognition rate of one character unit by determining candidate order for recognition object image information in a read object range according to the position of the recognition object image information. SOLUTION: Image data are read out (S1), the image is segmented into lines (S2), and image data on characters are taken out of the lines, character by character (S3). Then the segmented image data are recognized (S4) to generate recognition candidates (5), and a 1st candidate is determined in a combination of the candidates by a linguistic process (retrieval by a spelling collector for English and a Chinese character dictionary for Japanese) (S6). Then, a candidate order changing process based upon character positions is performed (S7). The determined 1st candidate is displayed (S8) and a user corrects it (S9). Consequently, the recognition rate (recognition rate of, specially, index numbers of a document in hierarchical structure) in character units is improved.
