FIELD: physics, computer engineering.
SUBSTANCE: present invention relates to an apparatus and a method of controlling display of an image, which can be used to detect an object in the vicinity of a display device. A display device controller is used to change display from a first display mode to a second display mode once an object is not detected during a defined period of time. The display mode is then restored to the first display mode when a sensor detects an object in the vicinity of the display device. In another aspect, the display device controller changes display from the second display mode to the first display mode when the sensor detects an object in the vicinity of the display device, where the second display mode has lower power consumption than the first display mode.
EFFECT: easier display restoration operations for the user.
