• processing circuitry that
• selects, from a plurality of types of the association information, particular association information to be associated with an acquired registration target image specified as a target to be newly registered in the registration memory, the selected association information including an application program to be activated in the retrieval terminal device and a value to be used by the activated application program, and
• performs setting of a setting item that depends on a type of the selected association information;
• and
• a transmitter that transmits the registration target image and the selected association information in which the setting item is set, to the image retrieval device to be registered in an associated manner in the registration memory.
