Abstract
PURPOSE: Development of the clipping circuit effective for digital video signal 1 and the digital signal 2 to set the clipping level are sent to the subtracting circuit 3. The decision circuit 4 opens the gate 5 only when the difference signal from the subtracting circuit 3 is positive (when the video signal level is higher than the clipping level), and the subtracting circuit 6 subtracts the difference signal from the video signal 1. When the vider signal level is lower than the clipping level, the video signal is firectly sent out of the circuit 7 as the output 7, and when higher than that, the difference signal representing the level difference is impressed on the subtracting circuit 6 through the circuit 3 and the gate 5. This defference signal is subtracted from the video signal 1 through the subtracting circuit 6, and the vider signal on the same level as the clipping level comes out as the output 7.
