Abstract: An image processing system includes a first terminal and a second terminal communicably connected to each other. The first terminal includes an image data acquisition unit configured to acquire image data related to an image of a predetermined space from a camera that photographs the predetermined space. At least one of the first terminal or the second terminal includes an analysis unit configured to analyze whether skeletal data relating to a structure of a body of a person included in the image are similar to predetermined reference skeletal data. The second terminal includes a detection unit configured to detect a predetermined event based on a result of the analysis, and an output unit configured to output result information that is a result of the detection.
