5. An access control method for controlling an access to an image signal through a network, the method comprising steps of:
-
receiving additional information indicating photographic conditions for the image signal through the network;
comparing the additional information indicating the photographic conditions for said received image signal with additional information indicating photographic conditions for an access target image signal, and determining whether the photographic conditions for said received image signal and the photographic conditions for said access target image signal satisfy a predetermined relationship; and
permitting the access to said access target image signal if a comparison result shows that the photographic conditions for said received image signal and the photographic conditions for said access target image signal satisfy the predetermined relationship. - View Dependent Claims (6, 7)

8. An access control program for causing a control section included in an access control apparatus that controls an access to an image signal through a network, to execute steps of:
-
receiving additional information indicating photographic conditions for the image signal through the network;
comparing the additional information indicating the photographic conditions for said received image signal with additional information indicating photographic conditions for an access target image signal, and determining whether the photographic conditions for said received image signal and the photographic conditions for said access target image signal satisfy a predetermined relationship; and
permitting the access to said access target image signal if a comparison result shows that the photographic conditions for said received image signal and the photographic conditions for said access target image signal satisfy the predetermined relationship.
