Title: Ghost eliminating device
Inventor: TAKAGUCHI TATSUYOSHI
IPC: H04N5/21
Filed: 1989-02-28
Abstract: PURPOSE:To eliminate ghost by comparing waveforms of an output signal from a synthesis circuit with a reference signal from a reference waveform generating circuit and giving a tap gain to a filter section in response to the result of comparison. CONSTITUTION:A minute signal whose level is below a prescribed level among output signals of an HPF 22 is regarded as a noise component and the minute level is suppressed by an amplitude limiter 23 of the next stage, synthesized by a synthesis circuit 24 and the result is fed to a waveform conversion circuit 18. A waveform comparator circuit 17 compares a substantial reference signal waveform calculated in advance by a reference waveform generating circuit 18 with an output waveform of the synthesis circuit 24 and a weighting setting circuit 12 applies waveform conversion (such as multiplication of a multiple and addition of it to preset tap gain) to an output of the waveform comparator circuit 17 based on the result of comparison (e.g. a difference) to decide the tap gain of the filter section 11. Thus, a video signal whose ghost is eliminated in an excellent way is outputted from the filter section 11.
