Claim 9:
10. A non-transitory computer-readable recording medium recording an abnormal-sound detection program that causes a computer to execute:
extracting a feature point of a diagnosis object from a video of the diagnosis object captured by a camera;
identifying an operation range of a diagnosis object, based on a movement range of the extracted feature point;
sensing a sound in which an abnormality has occurred from among sound collected by a microphone;
identifying, based on the collected sound, a generation position of the sound in which the abnormality is sensed; and
determining, based on the operation range and the identified generation position, whether the sound in which the abnormality is sensed is derived from the diagnosis object or derived from another element.
