<p>In an audio-accompanying moving-image taking apparatus, a noise period setting unit sets a second period with respect to an audio signal acquired by image-taking. The second period is a period between the endpoint of a first period which is a predetermined period starting from the timing when a drive instruction is made to a drive unit for driving a lens and the point in time when the drive unit stops driving according to the drive instruction. A noise level estimation unit estimates a noise level using the signal present in the second period set by the noise period setting unit. A noise suppression unit suppresses noise from the signal present in the second period using the noise level estimated by the noise estimation unit.</p> |
