FIELD: image forming devices.
SUBSTANCE: invention relates to a virtual viewpoint image generation system. Disclosed is a control device for a virtual viewpoint image generation system based on image data obtained by imaging from a plurality of directions using a plurality of cameras. Control device includes: a receiving unit configured to receive an instruction issued by a user to indicate a virtual viewpoint associated with generating a virtual viewpoint image, a receiving unit configured to obtain limitation information for indicating a limitation region, where the virtual viewpoint indication based on the received by the reception unit instruction is limited, wherein the restriction region varies in accordance with a parameter associated with the image data, and a notification unit configured to perform notification based on the restriction information obtained by the acquisition unit.
EFFECT: wider range of apparatus for generating images of a virtual viewpoint.
