To provide an imaging apparatus, an imaging method, and an imaging program allowing effective use of a waiting time during execution of noise-reduction processing on an image captured by a long-term imaging mode.

The imaging apparatus capable of imaging by the long-term imaging mode comprises: noise-reduction processing means which executes noise-reduction processing after long-second exposure performed in imaging a subject by the long-term imaging mode; and voice reproduction means which reproduces a voice file according to the exposure time of the exposure.
