IMAGE CAPTURING APPARATUS, SIGNAL PROCESSING APPARATUS AND METHOD

摘要

A signal processing apparatus reduces noise by generating an interpolated signal for a noise-containing period using audio signals in periods before and after the noise-containing period, and replacing an audio signal in the noise-containing period with the interpolated signal. Here, the signal processing apparatus determines whether a phoneme is the same or different between before and after the noise-containing period, and controls a method for generating the interpolated signal in accordance with a result of the determination.

主权项

1. A signal processing apparatus comprising:
a detection unit configured to detect, in a received audio signal, a noise-containing period in which noise is mixed in; a determination unit configured to determine whether a phoneme is the same or different between before and after the noise-containing period; and a noise reduction unit configured to reduce the noise by generating an interpolated signal for the noise-containing period using audio signals in backward and forward periods of the noise-containing period and replacing the audio signal of the noise-containing period with the interpolated signal, wherein the noise reduction unit controls a method for generating the interpolated signal in accordance with a result of the determination performed by the determination unit.
