Abstract
A change of a color tone of an image to be displayed is suppressed. A liquid crystal display device (1) displays an original image having a first dynamic range in a second dynamic range narrower than the first dynamic range. The liquid crystal display device includes a display control circuit (50) that lowers luminance of a dominant color having luminance higher than predetermined luminance to the predetermined luminance or less and lowers luminance of a non-dominant color.
Claims11
A display device that displays an original image, which includes a plurality of picture elements and has a first dynamic range, in a second dynamic range narrower than the first dynamic range,
- each of the plurality of picture elements being displayed by a plurality of colors or a combination of the plurality of colors, and
- image data, which indicates the original data, having a plurality of gradation values corresponding to the plurality of colors in each of the plurality of picture elements,
- the display device comprising
- a display control unit
- that sets, among the plurality of colors, a color corresponding to a maximum gradation value of gradation values of the picture element to a dominant color and sets a color other than the dominant color to a non-dominant color, and
- that lowers luminance of a dominant color having luminance higher than predetermined luminance to be the predetermined luminance or less and lowers luminance of the non-dominant color.
