Abstract

PURPOSE: To detect a blank securely even in a wide range of the moving speed of a scanner by fixing the lower limit period and upper limit period of blank detection corresponding to the number of frames satisfying the permissible conditions of the discrimination of a character image.
CONSTITUTION: When an observed patten satisfies detection conditions and three frames of it continues, counter 241 counts up by three. When scanner 7 moves and the following frames do not satisfy the conditions, the control part stops counter 241 and enables the counting of counter 242. Then, FF245 is initially reset and ROM243 outputs a value twice the value of counter 241, i.e. 6 to comparator 244, so that as the value of counter 242 reaches 6, blank detections signnal BU will be supplied to editing part 12. The output of comparator 244, on the other hand, sets FF245, and consequently ROM243 outputs the value five times the count value of counter 241, namely, 15 to comparator 244. Therefore, as counter 242 counts up to 15, scan end EOL is outputted to editing part 12.
