Abstract:
Systems and methods are disclosed for reducing unwanted noise during image capture. The noise may be airborne or structure-borne. For example, airborne sound may be sound that is emitted from a motor of a motorized gimbal into the air, which is then detected by a microphone of an imaging device along with the desired sound. Structure-borne noise may include vibrations from the motor that reach the microphone. Structure-borne noise may lead to local acoustic pressure variation by the microphone or pure vibration of the microphone.
