Abstract:
1. An imaging device comprising: a movie shooting unit for shooting a movie; a signal conversion unit for converting sound generated during the shooting of the movie into a sound signal; a subject determination unit for predicting or recognizing a specific subject; a noise detection unit for detecting noise included in the sound generated during the shooting of the movie; a noise reduction unit for reducing a noise signal from the sound signal; a voice detection unit for detecting a non-noise signal from the sound signal; and a noise reduction performance change unit for decreasing performance of the noise reduction unit for reducing the noise signal when the subject determination unit predicts or recognizes the specific subject, wherein: the voice detection unit detects the non-noise signal from the sound signal in a range from a lower-limit threshold to an upper-limit threshold of a frequency of the sound signal; and when the subject determination unit predicts or recognizes the specific subject, the voice detection unit lowers the lower-limit threshold.
