Abstract
PURPOSE: To ensure sharp printed picture through constant read-in level for letter background and symbols independently of the change in the background color of original, by using a drum for the original feeding and processing the concentration of reflection on the surface of the drum to a given output.
CONSTITUTION: The original feeding drum 8 is placed by opposing the image sensor 6. The concentration of reflection at the surface of the drum 8 is lower than the output a of the white original and it is processed that higher output is obtained than the output a' of the original darker in the background color. Accordingly, when the original darker in the background color having smaller width than the read-in width is transmitted, the maximum output is the background color d of the drum 8, and the slice level SLd can be set. The slice level SLd is lower than the output a' of the ground color part of the original and it is set at higher position than the output b of the letters and symbols described on the original, sharp printed picture can be obtained without the error of judgement for the information of white and black.
