Abstract

PURPOSE:To achieve a filter device in which ''fog'' effect can be given to a PCM color video signal continuously, by constituting a circulation type digital filter through the use of secondary correlation of subcarrier wave of PCM color video signals. CONSTITUTION:Either one of video signals applied to terminals 5 and 6 is selected at a horizontal filter circuit 1, the circuit 1 is operated with the horizontal control signal HC from a terminal 7 and the clock from a terminal 9, and an output (m) is applied to a vertical filter circuit 2. On the other hand, with the input of a horizontal delay circuit 3, the input video signal not selected with the input of the horizontal filter circuit 1 is delayed by the total delay time of the horizontal filter circuit 1 and the vertical filter circuit 2 and outputted to terminals 12, 13 from OUT1 or OUT2. The vertical control signal VC from a terminal 8 is delayed by the delay amount in the circuit 1 and applied to the circuit 2, and in this case, the circuit 2 is operated with the signal VC from the circuit 3. Thus, two video signals can easily be synthesized to achieve ''fog'' effect.
