Abstract
An electronic apparatus with backlit display and input device allowing reduced power consumption while maintaining necessary brightness is disclosed. A mode detecting section detects a currently set operation mode when performing a function. The brightness of the backlighting is controlled depending on the currently set operation mode. In the case of a data input mode, the brightness of the backlighting is reduced.
Claims14
An electronic apparatus comprising:
- a display section;
- an input section having a plurality of keys;
- a backlighting section for backlighting the display section and/or the input section;
- a mode detecting section for detecting a currently set operation mode that is one of a plurality of different predetermined operation modes, wherein the plurality of different predetermined operation modes include a data input mode and a data display mode, wherein the backlighting control section reduces the brightness of the backlighting section when the data input mode has been set;
- and
- further comprising:
- an information processing section on which one of a plurality of programs runs to generate a corresponding function;
- and
- wherein the plurality of programs include a brightness designation program, wherein the backlighting control section controls brightness of the backlighting section depending on a designated brightness level obtained by running the brightness designation program on the information processing section.
In an electronic apparatus having a display section, an input section having a plurality of keys, and a backlighting section for backlighting the display section and/or the input section, a method for controlling brightness of the backlighting section, comprising the steps of:
- a) detecting a currently set operation mode that is one of a plurality of different predetermined operation modes when preforming a function;
- and
- b) controlling brightness of the backlighting section depending on the currently set operation mode;
- c) executing one of a plurality of programs to generate a corresponding one of the plurality of different predetermined operating modes wherein one of the plurality of programs includes a brightness designation program wherein backlighting is controlled depending on a designated brightness level obtained by running the brightness designation program;
- wherein the plurality of different predetermined operation modes include a data input mode and a data display mode, wherein, in the step (b), when the data input mode has been set, the brightness of the backlighting section is reduced.
