Imaging apparatus with adjustable noise level reduction
View Patent ↗Provided is an imaging apparatus that performs sound processing suitable for each type of AF operation according to a lens f-number so that recorded sound is clear and contains little noise. The imaging apparatus includes a lens, a microphone for recording sound, and a filter configured to reduce noise contained in an output signal of the microphone. The noise reduction level of the filter is controlled according to the lens f-number so that the noise reduction level of the filter is increased when the lens f-number is large than when the lens f-number is small.
1. An imaging apparatus comprising:
a lens;
a microphone for recording sound; and
a filter configured to reduce noise contained in an output signal of the microphone,
wherein a noise reduction level of the filter is controlled according to an f-number of the lens such that the noise reduction level of the filter is increased more when the f-number of the lens is large than when the f-number of the lens is small.
2. The imaging apparatus according to claim 1 ,
wherein the filter is configured to reduce noise generated when an autofocusing operation is performed.
