<P>PROBLEM TO BE SOLVED: To reduce luminance differences between a plurality of display screens and to improve visibility of the display screens. <P>SOLUTION: A portable terminal 10 includes an illuminance sensor 11, a processor 12 and a plurality of LCD units 151a and 152a. The processor 12 acquires an illuminance from the illuminance sensor 11. The processor 12 acquires luminance setting values of the LCD units 151a and 152a respectively, from a setting value reference table 131 in which the illuminance, the luminance setting value of the LCD unit 151a and the luminance setting value of the LCD unit 152a are associated with each other and stored. The processor 12 notifies the LCD unit 151a of the acquired luminance setting value of the LCD unit 151a, and notifies the LCD unit 152a of the acquired luminance setting value of the LCD unit 152a. <P>COPYRIGHT: (C)2013,JPO&INPIT |
