Abstract
A transversal filter filters an input video signal with a filtering characteristic determined by tap gains. A row of error signals are generated on the basis of a difference between a ghost cancel reference signal in the input video signal and a predetermined reference signal. A magnification setting circuit sets a first magnification in accordance with the row of the error signals. A weight setting circuit converts an output signal from the magnification setting circuit into weighting data and feeding the weighting data into the transversal filter as the tap gains. The weight setting circuit functions to correct the first magnification into a second magnification in accordance with row numbers denoting the respective error signals in the row.
