AUDIO-SIGNAL-PROCESSING APPARATUS, IMAGING APPARATUS, AUDIO-SIGNAL-PROCESSING METHOD, PROGRAM, AND RECORDING MEDIUM
Document Type and Number:
WIPO Patent Application WO/2013/015011
Kind Code:
A1
Abstract:
[Problem] To detect, with a high degree of precision, a noise interval including operational noise in a pulse state, from an audio signal only, collected without using drive-control information from a drive apparatus; and to improve the precision of noise reduction. [Solution] An audio-signal-processing apparatus is provided with: a feature-value extractor for extracting from an audio signal obtained from a noise collector a feature value showing operation noise in a pulse state generated from a noise generator installed in the same cabinet with the noise collector; and a noise-assessment unit for assessing, on the basis of the feature value, whether the operation noise is included in the audio signal.
