Abstract: A processing apparatus (10) including: an event extraction unit (11) that extracts, for each image of a time-series image group, an event in which a person and an object relate to each other; an event information generation unit (12) that generates event information indicating a time-series change of a first event defined by a first person, a first object, and a first relationship between a person and an object and also indicating a time-series change of a second event defined by a second person, a second object, and a second relationship between a person and an object; a causal relationship computation unit (13) that computes a score indicating a causal relationship between the first event and the second event; and an output unit (14) that outputs information indicating the first event and the second event for which the score satisfies a predetermined condition.
