Abstract
PURPOSE: To simplify character pattern extraction by judging the direction of a character array by fixing directions of the upper and lower terminals of a character block by detecting the upper and lower terminals, by measuring longitudinal and lateral lengths, and by regarding the greater one as the height of a printing type.
CONSTITUTION: Mail is scanned and the obtained signal is photoelectrically converted and quantized into a binary level to determine the direction of a printing type by a direction detector. A quantized video signal is inputted to pattern shift register 11 and then shifted in sequence by the output clock of clock circuit 40. Then, the lower, upper and left terminals of the character are detected by detectors 12W14, whose outputs are stored in register 38. Next, when the lower, upper and left terminals of a character block are detected, detector 15 judges it one character block. Then, size detectors 17 and 18 measure the block size and comparator 21 makes a comparison between longitudinal and lateral sizes; and counters 25 and 26 start counting by the output of the comparator and comparator 27 makes a comparison, so that when the lateral size is greater, the character array will be judged to be lateral. Thus, the direction of the character array is judged at a high speed.
