Abstract
PURPOSE: To simplify the constitution, by providing the picture pick up mark on the required picture of original and picking up the picture only duplicated with the picture pick up mark through read-in with the image sensor.
CONSTITUTION: The output signal of the image sensor 7 is splitted with the discrimination circuit 10 into two slice levels of the lightness between the original base paper and picture pick up mark 3 and that between the picture pick up mark 3 and picture 2. The filter circuit 11 picks up only the picture pick up mark 3 signal, and the gate circuit 12 compares the signal of the picture pick up mark 3 with that of the picture 2, and the picture signal only corresponding to the location of the picture pick up mark 3 is picked up and processing such as recording is made.
