Title:
SIGNAL PROCESSING DEVICE, TELEVISION, SIGNAL PROCESSING METHOD, PROGRAM, AND RECORDING MEDIUM
Document Type and Number:
WIPO Patent Application WO/2012/018093
Kind Code:
A1
Abstract:
A sound processing unit (112) is provided with: an equalizer part (1121) which causes n biquadratic filters having individual characteristics to act sequentially on a sound signal; an estimating part (1124) which estimates the magnitude of an outputted noise from the equalizer part by causing the n filters to act in sequence for permutations which could be configured with the n filters; and a setting part (1123) which substantially changes the sequence of actions of the n filters by replacing coefficients of the filters on the basis of the estimated magnitude such that the outputted noise decreases.
