A sound-source-candidate extraction system for extracting a candidate of a sound source that causes a noise propagated inside or outside a cabin of a vehicle. The sound-source-candidate extraction system includes: (a) an imaging device configured to acquire data of an image inside or outside the cabin of the vehicle; and (b) an extracting device configured to extract the candidate of the sound source, depending on a difference between first and second image data acquired by the imaging device, wherein the first image data is the data of the image before generation of the noise, and the second image data is the data of the image upon or after the generation of the noise. Also disclosed is a sound-source search method using the sound-source-candidate extraction system.
