Abstract
A low-resolution is displayed at high resolution and power consumption is reduced. Resolution is made higher by super-resolution processing. Then, display is performed with the luminance of a backlight controlled by local dimming after the super resolution processing. By controlling the luminance of the backlight, power consumption can be reduced. Further, by performing the local dimming after the super-resolution processing, accurate display can be performed.
Claims10
A method for driving an electronic device comprising a display device, the method comprising:
- forming first image data by super-resolution processing from second image data;
- and
- displaying the first image data on the display device,
- wherein the electronic device is configured to vary intensity of the super-resolution processing on each portion of the second image data depending on content of the second image data.
A method for driving an electronic device comprising a display device, the method comprising:
- forming first image data by super-resolution processing from second image data;
- and
- displaying the first image data on the display device,
- wherein, when the second image data contains a flat portion and a textual portion, intensity of the super-resolution processing of the flat portion is different from intensity of the super-resolution processing of the textual portion.
