Abstract
A control section of a portable phone controls a viewing-angle changing section that changes a viewing angle of an image display section-and controls the viewing angle of the image display section on the basis of a status of use of various devices. 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.
