In a wind noise reduction device that reduces wind noise contained in an input sound signal to generate a corrected sound signal, when a predetermined band including the band of the wind noise is a first band and a predetermined band higher in frequency than the first band is a second band, the wind noise reduction device includes: a first corrector that has a signal generator generating, based on a sound signal (i) contained in the input sound signal and lying in a band higher in frequency than the first band, a sound signal (ii) lying in the first band and different from a sound signal (iii) contained in the input sound signal and lying in the first band, and that generates a first corrected sound signal based on the sound signal (ii) generated by the signal generator; a second corrector that reduces the signal level of a sound signal (iv) contained in the input sound signal and lying in the second band to thereby generate a second corrected sound signal as a sound signal (v) having the wind noise reduced and lying in the second band; and a corrected sound signal outputter that outputs the corrected sound signal based on the first and second corrected sound signals.

Wind noise reduction device

The imaging device is provided with at least one imaging part to obtain images through shooting and at least one sound-collection part to obtain audio, collecting it together with the shooting of the imaging part, and at least one display part to display images. It performs audio-correction processing of audio obtained through the sound-collection part according to the relative relationship between the direction in which the display part displays images and the direction in which the imaging part shoots.

Imaging device and playback device

Sound correction processing is performed for a sound signal obtained from a sound collecting portion. In particular, sound correction processing is performed after determining what is performed as the sound correction processing based on an image signal paired with a sound signal, the image signal obtained from an imaging portion, the sound signal, control data of the imaging portion, and the like.
