Document Type and Number:
WIPO Patent Application WO/2011/055834
Kind Code:
A1
Abstract:
Provided is a signal processing technology capable of suppressing various noises including unknown noises without storing information relating to a large number of noises in advance. In order to suppress noises intermingled in a degraded signal, noise information relating to the noises in the degraded signal is corrected using correction information first. Corrected noise information is determined by the correction. The noises in the degraded signal are suppressed using the determined corrected noise information. The correction information is updated on the basis of noise suppression results of the noises suppressed as above.
