Ghost cancelling method and apparatus which perform a correlative operation to speed processing

摘要

There is provided a ghost cancelling method and apparatus in which a video signal is input to a transversal filter to generate a ghost correction signal and the ghost correction signal is mixed with the original video signal to automatically cancel a ghost. To improve the ghost cancelling speed, a correlative operation is performed between the video signal input and a ghost cancelling reference signal, to thereby determine an initial filter coefficient of the transversal filter.
