1. An apparatus comprising:
- a recording unit configured to record a video image;
a detection unit configured to detect an object event in which a state of an object changes from the video image;
a generation unit configured to generate, when the object event is detected from the video image, event information associating the object event with an identifier of the object and a time when the object event occurred;
