Abstract

Reduction in reproduction quality is suppressed in an imaging device that images a sound and a moving image. A frame rate converter converts a frame rate of a frame captured outside a predetermined period among a plurality of frames captured at a predetermined frame rate to a low frame rate lower than the predetermined frame rate. A duplication unit duplicates an original sound signal recorded over the predetermined period to generate a plurality of duplicated sound signals each of which is identical to the original sound signal. The audio signal processing unit performs different signal processing on each of the plurality of duplicated sound signals.
