1. An object monitoring system comprising:
a memory storing instructions; and
at least one processor configured to process the instructions to:
create a state image by capturing a state occurring in a first range,
create a monitoring target image by capturing a monitoring target present in a second range,
detect a specific state from the state image,
extract, from the monitoring target image created after the specific state has been detected, a feature used for specifying the monitoring target, based on the status of the monitoring target, and
specify, for each type of specific state, as an object, a monitoring target which appears with a high frequency in a plurality of monitoring target images.
