Title:
IMAGE-CAPTURING DEVICE
Document Type and Number:
Japanese Patent JP2016009039
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To perform a noise reduction process appropriately.SOLUTION: An image-capturing device has a noise cancellation unit for comparing, for each frequency, the signal level of the frequency spectrum of an inputted sound signal and the level of a noise profile, and performs level suppression. When the inputted sound level is below a predetermined threshold, a drive unit compares a signal level between the frequency spectrum before drive and the frequency spectrum whose level is suppressed by the noise cancellation unit during drive, and corrects the level of the noise profile.
