The system comprises a positional information acquisition unit that acquires, from each electronic device, positional information in a plurality of pieces in chronological order, by which a position of the electronic device is identifiable; a candidate selection unit that selects, as a distribution candidate for the content, the electronic device in which a time after elapse of an estimated travel time from a current time is before a time limit corresponding to the content; and a content distribution unit that distributes the content to the electronic device selected for the content by the candidate selection unit.

Abstract: Provided is an image display system comprising a camera unit and a display unit that displays an image captured by the camera unit. The system comprises: a marker-detection unit that detects a marker specified in advance in the image captured by the camera unit; a content-reproduction unit that reproduces the content corresponding to a marker in a display area of the display unit; an event-detection unit that detects whether an event for changing a display-mode of the content has occurred; and an area-change unit that changes a display section where the content is reproduced to a display section that is in accordance with the detected event. The content-reproduction unit reproduces, in the changed display section, the content that had been reproduced.
