Abstract

PURPOSE:To reduce the loss of the signal level of the entered picture, by outputting an electric signal concerning only one picture on a basis of the threshold set between two signal levels when the first and the second pictures are the same color and different in density. CONSTITUTION:Character fame 10 is printed with a density lower than character 2. Consequently, if threshold 11 is set to the level of the picture signal obtained from the sensor when this picture is scanned on straight line 3 and is subjected to photoelectric conversion, picture signal 12 of the character frame is eliminated to take out picture signal 13 of the entered picture.
