An image processing system includes, a reconfigurable circuit, a storage unit storing first configuration data for a first logical circuit in a predetermined area on the reconfigurable circuit, and second configuration data for a second logical circuit in the predetermined area, and a configuration unit configured to perform first configuration processing for configuring the first logical circuit in the predetermined area, by using the stored first configuration data and predetermined configuration data, on the predetermined area and a different area, and to perform second configuration processing for configuring the second logical circuit in the predetermined area, by using the stored second configuration data and predetermined configuration data, on the predetermined area and the different area. The predetermined configuration data used for the first configuration processing and the predetermined configuration data used for the second configuration processing are not stored in a duplicated way.
