DISPLAY DEVICE, DISPLAY SYSTEM, AND COMPUTER-READABLE RECORDING MEDIUM IN WHICH LUMINANCE CONTROL PROGRAM IS STORED
First Claim
1. A display device comprising:
- a display unit;
a sensor for detecting an ambient luminance of said display unit;
a luminance control unit for controlling a luminance of said display unit in a luminance control mode selected from a first luminance control mode in which the luminance of the display unit is changed in terms of the ambient luminance detected by said sensor, a second luminance control mode in which the luminance of said display unit is maintained at a predetermined luminance that has been previously determined and a third luminance control mode in which the luminance of said display unit is maintained at a minimum luminance;
a first operating unit being operated to change the luminance control mode, in which said luminance control unit currently controls the luminance of said display unit; and
a change controlling unit for changing the luminance control mode, in which said luminance control unit currently controls the luminance of said display unit, responsive to operating said first operating unit.

Abstract
To improve the convenience of users and facilitate a change into a luminance control mode high in power save effect, the display device includes a luminance control unit for controlling a luminance of the display unit in a luminance control mode selected from a first luminance control mode in which the luminance of the display unit is changed according to the ambient luminance detected by the sensor, a second luminance control mode in which the luminance is maintained at a predetermined luminance previously determined and a third luminance control mode in which the luminance is maintained at a minimum luminance; a first operating unit being operated to change the luminance control mode; and a change controlling unit for changing the luminance control mode, in which the luminance control unit currently controls the luminance of the display unit, responsive to operating the first operating unit.
