PROBLEM TO BE SOLVED: To provide a ghost eliminating device that realizes a stable operation even on the occurrence of an excessive proximity ghost. SOLUTION: A proximity ghost detection section that sets a tap coefficient group to a transversal filter for generating a pseudo proximity ghost of an acyclic proximity ghost eliminating section, is provided with a means (13) that applies Fourier transform to a digital signal extracted from an proximity ghost area in a received television signal, a means (14) that divides a reference waveform Fourier coefficient group for ghost detection stored in advance by the Fourier coefficient group, a means (15) that applies inverse Fourier transform to the quotient, a means (16) that generates a time series signal group and a means (18) that shares the excess amplitude to signals in the vicinity of the time series when the amplitude of the time series signal group exceeds the amplitude applicable to the pseudo proximity ghost generating transversal filter and supplies the tap coefficient group to the pseudo proximity ghost generating transversal filter.
