Abstract

PURPOSE: To enable to obtain the recording picture in fidelity with original, by taking logical sum between the logical product output of 1H delay signal and the sliced signal with the second level, and the sliced signal with the first level through the output.
CONSTITUTION: The video signal read in for the information on the original is sliced 13,15 with the first and second level for a binary number either of white or black. Further, the logical product 17 between the signal sliced 15 with the second level and the output signal slicing 15 the video signal of pre-scanning line with the second level, is taken and output is made by taking the logical sum 18 between the output signal and the output signal sliced with the first level. Thus, noise can be eliminated and reproducibility is improved to lateral lines, allowing to obtain the recording picture in fidelity with the original.
