Abstract

PURPOSE: To enable to reduce the rate of misreading, by calculating the similarity of the pattern in the buffer area and the standard pattern with the similarity calculation circuit, and detecting the maximum.
CONSTITUTION: The demarcation processing section 100 demarcates the video data into the character pattern of one character, it is fined at the character pick up circuit 200 to pick up the derectivity of connection and to normalize the size, and the gradation processing circuit 300 reads in the pattern in the buffer area to perform gradation processing to each pattern. Next, the similarity calculation circuit 400 reads in the pattern in the buffer area to calculate the similarity with each of the standard patterns stored in itself. The maximum similarity is detected and the main computer 70 writes in the result of recognition in the floppy disc 500 in given format. Thus, the rate of misreading can be reduced.
