Abstract
An imaging apparatus includes an external-audio microphone that collects an external sound that occurs outside the imaging apparatus, a noise reference microphone that obtains drive noise of the imaging apparatus or an external apparatus connected to the imaging apparatus, a detection unit that detects a noise period during which the drive noise occurs, an updating unit that updates background noise based on an audio signal obtained by the noise reference microphone during a no-noise period determined by the detection unit as a period in which no noise occurs, a generation unit that generates an audio signal of the drive noise from the audio signal obtained by the noise reference microphone and the updated background noise, and a noise reduction unit that reduces the audio signal of the drive noise generated by the generation unit from the audio signal obtained by the external-audio microphone during the noise period.
