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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Imaging apparatus with adjustable noise level reduction","description":"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.
