Abstract

PURPOSE: To detect the objective character area, by providing the means to detect the boundary line for the character area such as letters which are distinguished with the line.
CONSTITUTION: The post card 11 on the carry path 17 is scanned with the scanning line 18, and each part of the paper is outputted as the binary pattern signal. The boundary line 12 is detected with the output pattern signal from the scanner 18. The boundary line 12 is generally a comparatively long straight line and when the number of black bits in continuity as to main scanning is more than a given value, it is detected and this is taken as the boundary line. That is, the black bit counter 27 counts the length when black is kept on the scanning line and it is reset when white comes or one scanning is finished. The output of the counter 27 is compared with the set value T of the comparison value register 29 at the comparator 28 and when the counter output exceeds the T, it can be regarded as the boundary line 12.
