Picture display controller, moving-picture information transmission/reception system, picture display controlling method, moving-picture information transmitting/receiving method, and computer program

A picture display controller can display picture data taken from a plurality of viewpoints in a flexible manner. For displaying moving-picture data taken from the plurality of viewpoints, read from a storage medium or received from a server, switching can be made at any time between a manual mode in which a picture is selected or synthesized based on designated information such as viewpoint position included in a viewpoint setting command from the controller operated by the user or from the sensor such as head tracker and displayed and a preset mode in which moving-picture data taken from different viewpoints are selected one after another according to a picture display program preset for a moving picture and displayed. With this system design, a user's setting can be made effective only for a picture portion in which he is interested.
