IMAGE OUTPUT SYSTEM AND IMAGE OUTPUT METHOD

PROBLEM TO BE SOLVED: To provide a photograph as well as additional information regarding the photographed location in a service for taking photographs at a tourist spot or in a vehicle.SOLUTION: A photographing terminal 22-1 transmits an image photographed by a photographing device 23-1 to a server 40 along with an identification number and addition information acquired from an ID card reading device 21-1. The server 40 stores the additional information received from the photographing terminal 22-1 and also encodes data indicating a location in which the additional information is stored, to generate print data having the code embedded in the photographed image as a digital watermark and store the generated print data in association with the identification information. An image output device 32 receives from the server 40 the print data corresponding to the identification number acquired from the IC card reading device 31 and prints it on the basis of a print order from a user. A user terminal 50 reads the digital watermark embedded in printed matter, accesses an URL indicated by the read code, and receives the additional information from the server 40 and then outputs it.
