INFORMATION PROCESSING DEVICE, AUXILIARY DEVICE THEREFOR, INFORMATION PROCESSING SYSTEM, CONTROL METHOD THEREFOR, AND CONTROL PROGRAM

WIPO Patent Application WO/2011/055832

A1

Disclosed is a noise suppression technique for suppressing various types of noise including those that are not identified, without storing many pieces of noise information in advance. Specifically disclosed is an auxiliary device connectable to an information processing device. The information processing device is provided with: a means for suppressing noise in a deteriorated signal using noise information, generating noise information on the basis of the noise suppression result, and suppressing noise in a deteriorated signal using the generated noise information; and a noise information generation means for updating noise information on the basis of the result of suppression of noise in a deteriorated signal. The auxiliary device is provided with a mechanism unit for generating noise to be suppressed by a noise suppression means, and a mechanism control unit for controlling the mechanism unit to generate noise at the point in time when the noise suppression means performs noise suppression processing.
