Abstract

PURPOSE:To improve the read accuracy, by deciding a subset from a result of recognition by a recognition dictionary, to every character-string partitioned by a blank or a specific symbol in a read field, and recognizing the character- string again by use of a recognition dictionart containing said subset only. CONSTITUTION:A video signal obtained by scanning a chaacter entered or printed in a slip 1, by a scanning part 2 is applied to a pre-processing part 6, the video signal is binary-coded by the pre-processing part 6, and a character pattern is supplied to a recognition part 6. In this recognition part 7, the character pattern is recognized by referring to a recognition dictionary 8, and its recognition result is provided to a control part 9. subsequently, a character-string 3 of alphanumeric and a character-string 4 of ''Katakana'' (square form of Japanese syllabary), which are partitioned by one blank are entered in a read field 2 of the slip 1. The field 2 of this slip 1 is recognized by use of a recognition dictionary containing both of the whole character-strings in the recognition part 7, a subset is decided by said recognition result, subsequently the character-strings are recognized again by use of a recognition dictionary containing the subset only, and the read accuracy is improved.
