PURPOSE:To improve the ghost eliminating performance, by connecting an AGC circuit to an output side of a transversal filter and storing the output of the AGC circuit in a memory as ghost information after A/D-converting the output of the AGC circuit. CONSTITUTION:The AGC circuit 12 is provided at the succeeding stage of the transversal filter 5, an output of the AGC circuit 12 is given to a video signal processing amplifier circuit and a chroma signal processing amplifier circuit at the succeeding stage and the other output is applied to an A/D converter 7. The output of the A/D converter 7 is stored in a memory 11 as ghost information and the ghost information stored in the memory 11 is processed at an operating circuit 10, the output controls a weighting coefficient correcting circuit 6 so as to correct the weighting coefficient of the transversal filter 5. |
