Abstract
Provided are an imaging device, program, memory medium, and noise reduction method capable of appropriately reducing noise without causing degradation in a target sound such as voice. The imaging device of the present invention has: a video imaging unit for capturing video; a signal converter for converting a sound generated during video capture to a sound signal; subject determination units that predict or recognize a specific subject; a noise detector for detecting noise included in the sound generated during video capture; a noise reduction unit for reducing the noise signal from the sound signal; a voice detector for detecting non-noise signals in the sound signal; and a noise reduction performance change unit that lowers the noise signal reduction performance of the noise reduction unit when the subject determination units predict or recognize the specific subject.
