Abstract:
1. A control device arranged to control a viewing angle of a display device, said control device comprising: a storing section arranged to store in advance a correspondence relationship between a plurality of devices capable of being used and the viewing angle; a device-in-use detecting section arranged to detect use of each of the plurality of devices that are actually being used; a viewing-angle retrieving section arranged to retrieve a viewing angle corresponding to the plurality of devices that are actually being used as detected by the device-in-use detecting section from the correspondence relationship stored in the storing section; and a viewing-angle controlling section arranged to control the viewing angle of the display device on a basis of the viewing angle retrieved by the viewing-angle retrieving section; wherein the correspondence relationship includes priority information for each of the plurality of devices capable of being used, such that when the device-in-use detecting section detects the use of the plurality of devices that are actually being used, the viewing-angle controlling section is arranged to control the viewing angle of the display device to be a viewing angle corresponding to one of the plurality of devices that are actually being used that has a highest priority among the plurality of devices that are actually being used as detected by the device-in-use detection section.
