Abstract
A method for cancelling ghost effects in an image signal processor which is capable of enhancing a convergence rate of a coefficient of a filter and a performance of cancelling ghost effects in a system, by alternately performing the updatings of the coefficients of an FIR filter and an IIR filter in a system using both the FIR filter and the IIR filter, includes initializing an FIR filter bank and an IIR filter bank, updating the FIR filter bank by performing an algorithm for updating a coefficient of a filter with a data having a ghost effect and a data in which a reference GCR data is filtered by the IIR filter, updating the IIR filter bank by performing the algorithm for updating a coefficient of a filther with the reference GCR data and a data in which an X(z) is filtered by the FIR filter bank, and obtaining an FIR filter bank and an IIR filter bank in each of which an error is minimized.
