Abstract

PURPOSE:To improve the rate of character recognition by perfoming reading operation by using an adequate recognition dictionary for a subset for every character line. CONSTITUTION:In the field 2 of a document 1, a character line 3 of mixed numbers and alphabets and a character line 4 of KATAKANA(square form of Japanese syllabary) are written being sectioned with a blank. Those are converted 5 into a video signal. A preprocessing means 6 generates character pattern by using the video signal. A precognizing means 7 receives information on the document to know that the field 2 is a mixed field of a subset of alphanumeric data and another subset of KATAKANA data and that the character line is sectioned, subset by subset, and then sends the result of the recognition of the readout field 2 by a recognition dictionary 8 for the alphanumeric subset and the result of recognition by a recognition dictionary for the KATAKANA subset to the control means 9.
