Abstract
A display device for displaying image data includes: a gradation conversion circuit that converts a gradation of input image data; a display panel that displays the image data with the gradation converted by the gradation conversion circuit; an illuminance sensor that detects illuminance of an environment where the display device is placed; and a gamma characteristic corrector that controls a gradation conversion circuit so as to convert the gradation by use of a gamma characteristic corresponding to the detected illuminance.
Claims15
A display device comprising:
- a gradation conversion circuit that converts a gradation of input image data;
- a display panel that displays image data with the gradation converted by the gradation conversion circuit;
- an illuminance sensor that detects illuminance of an environment where the display device is placed;
- and
- a gamma characteristic corrector that controls a gradation conversion circuit so as to convert the gradation by use of a gamma characteristic corresponding to the detected illuminance.
A method for displaying image data, the method comprising:
- a gradation conversion step of converting a gradation of the image data input into a display device;
- a display step of displaying the image data with the gradation converted in the gradation conversion step;
- an illuminance detection step of detecting illuminance of an environment where the display device is placed;
- and
- a gamma characteristic correction step of performing control so as to convert the gradation by use of a gamma characteristic corresponding to the detected illuminance.
A mobile terminal, comprising:
- a display panel;
- and
- an opening and closing unit linked to the display panel so as to be switchable between a first position for exposing a front surface of the display panel and a second position for covering the front surface,
- wherein the opening and closing unit has at least one luminance sensor that is attached to a surface of the opening and closing unit facing the front surface when at the second position, and that detects luminance of the front surface.
