1. 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.

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.

13. 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. - View Dependent Claims (14)
