A virtual viewpoint image generation system generates a virtual viewpoint image based on a plurality of captured images obtained by capturing an image capturing target region from a plurality of different directions, and position information relating to a virtual viewpoint position. The system comprises: a plurality of image capturing apparatuses; a daisy-chain-type topology network; an obtainment unit configured to obtain the position information relating to the virtual viewpoint position; and a generation unit configured to generate the virtual viewpoint image based on the position information and the data based on each captured image of the plurality of image capturing apparatuses obtained via the daisy-chain-type topology network.
