A control unit controls a driving unit to drive an optical system in a first driving mode and controls a sound processing unit to process a sound signal in a first noise reduction processing mode in the case where a level of the sound signal obtained by a sound obtaining unit is lower than a predetermined level. The control unit controls the driving unit to drive the optical system in a second driving mode with a longer driving time than the first driving mode and controls the sound processing unit not to process the sound signal in the first noise reduction processing mode in the case where the level of the sound signal obtained by the sound obtaining unit is equal to or higher than the predetermined level.
