Claim of US Patent No. 9,288,370

1. An imaging apparatus comprising:
an imaging unit that generates an image signal corresponding to an image obtained by an optical system;
an audio obtaining unit that obtains an audio signal; and
a control unit that controls a driving operation of a component of the optical system so as to start driving in accordance
with a drive start instruction, to drive for a predetermined driving period, and to stop driving after the predetermined driving
period;

a determination unit that determines a noise period in which a noise is included in the audio signal obtained by the audio
obtaining unit,

where the determination unit performs an operation for determining the noise period in an analysis period which includes a
determined period from a driving stop timing of the component of the optical system and determines the noise period in the
analysis period in accordance with the obtained audio signal in the analysis period; and

an audio processing unit that reduces a noise from the audio signal in the noise period determined by the determination unit.
