Electronic appliance having magnifying-glass display function, display controlling method, and display control program
First Claim
1. A portable electronic device comprising:
- a display unit having a display screen;
a storage unit for storing information which is displayed on the display screen of the display unit;
a move amount detecting unit for detecting a move amount of the display unit in a substantially vertical direction with respect to the display screen; and
a display control unit for causing the information stored in the storage unit to be displayed on the display screen in a manner such that a display size of the information is dynamically changed in response to the move amount of the display unit in the substantially vertical direction detected by the move amount detecting unit;
wherein when the move amount detecting unit detects movement of the display unit in a direction directed from a rear surface of the display screen to a front surface of the display screen, the display control unit enlarges the information at a ratio in accordance with the detected move amount and displays the enlarged information, andwherein when the move amount detecting unit detects movement of the display unit in a direction directed from the front surface of the display screen to the rear surface of the display screen, the display control unit compresses the information at a ratio in accordance with the detected move amount and displays the compressed information.

Abstract
In a portable telephone, a sensor constructed of, for example, a 3-axial acceleration sensor is built in the vicinity of a display unit which is provided on a main body of the portable telephone. When a user moves the display unit along a vertical direction (Z-axis direction) with respect to a display screen thereof while the user holds the appliance main body, the sensor senses both a move direction and a move amount of the display unit, and thus, information displayed on the display screen of the display unit is enlarged, or compressed in display magnification defined in response to the sensed move amount. As a result, a display size of the information displayed on the display screen can be changed in such a manner that the user may have such a natural feeling achieved by moving a magnifying glass.
