An image processing apparatus includes an identification unit configured to execute identification processing for associating an object included in a first captured image captured by a first image-capturing apparatus with an object included in a second captured image captured by a second image-capturing apparatus different from the first image-capturing apparatus, a recording unit configured to record a result of the identification processing executed by the identification unit, and a determination unit configured to determine a state of a restriction condition based on the result of the identification processing recorded by the recording unit and the restriction condition relating to the identification processing set between the first image-capturing apparatus and the second image-capturing apparatus.
