Abstract: Provided is a technology which is able to detect an object with high accuracy. A signal processing apparatus 1 includes a generating unit 2 and a detecting unit 3. The generating unit 2 includes a function of generating, as a transmitting signal, a modulation wave whose frequency changes non-repetitively. The detecting unit 3 includes a function of fetching the transmitting signal and a receiving signal which is received by a receiving means that can receive a reflection signal generated when the transmitting signal is reflected by an object. The detecting unit 3 includes a function of detecting at least one of presence of the object, distance to the object, and moving speed of the object, based on correlation between the receiving signal and the transmitting signal.

Abstract: A monitoring device includes a crowd behavior analysis unit 21 and an abnormality degree calculation unit 24. The crowd behavior analysis unit 21 specifies a behavior pattern of a crowd from input video. The abnormality degree calculation unit 24 calculates an abnormality degree from a change of the behavior pattern.

Abstract: An action analysis device includes: an acoustic analysis unit 1 for analyzing input acoustic information, and generating acoustic analysis information indicating a feature of the acoustic information; a time difference determination unit 2 for determining a time difference between when an acoustic event identified by the acoustic analysis information occurs and when an event corresponding to the acoustic event occurs in input video obtained by capturing an image of a crowd; and an action analysis unit 3 for analyzing an action of the crowd corresponding to the acoustic event, using the input video, the acoustic analysis information, and the time difference.
