    Abstract: A control section of a portable phone controls a display on a main display section with a viewing angle that is variable. The control section includes: a viewing-angle obtaining section to obtain viewing-angle information about the viewing-angle of the main display section; and a viewing-angle display control section to control an image display section of the main display section to display the viewing-angle information obtained by the viewing-angle obtaining section. The viewing-angle information is obtainable from a viewing-angle control section. The viewing-angle control section controls a viewing-angle changing section. The viewing-angle changing section changes the viewing angle. It is possible to obtain the viewing-angle information as a result that an operation section conducts an operation to change the viewing angle, and/or as a result that an application executing section executes a predetermined application.

  • Publication number: 20070291024
    Abstract: A control section of a portable phone controls a viewing-angle changing section that changes a viewing angle of an image display section. The control section controls the viewing angle of the image display section on the basis of a status of use of various devices. Specifically, the control section includes: a device-in-use detecting section to detect use of the devices; a storage section to store a device/viewing-angle matching table containing a correspondence relationship between a device to be used and a viewing angle; a viewing-angle retrieving section to retrieve, from the table, a viewing angle for the device detected being in use by the device-in-use detecting section; and a viewing-angle control section to control the viewing-angle changing section on the basis of the viewing angle retrieved by the viewing-angle retrieving section. The foregoing allows the viewing angle to be controlled automatically on the basis of the status of use, with a few settings.
