Embodiment Construction

[0103] Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, the same numerals in different drawings refer to the same or similar elements unless otherwise indicated. The implementations described in the following exemplary examples do not represent all implementations consistent with this disclosure. Rather, they are merely examples of apparatuses and methods consistent with aspects of the present disclosure as recited in the appended claims.

[0104] In related technologies, generally, the same color gamut mapping method is used for each frame of display content displayed on the terminal. A frame of display content is usually superimposed by multiple layers (English: layers), but not every frame layer is suitable for color gamut mapping. For example, the lock screen interface of a smart phone includes: a status bar layer, a wallpa...

Abstract

The invention discloses a color gamut mapping method and a color gamut mapping device, and belongs to the technical field of display. The method comprises the following steps: acquiring layer characteristic information of at least one layer corresponding to display content; identifying the layer type of each layer according to the layer characteristic information; for each layer, selecting a color gamut mapping mode corresponding to the layer type, and using the color gamut mapping mode to map the layer to a corresponding color gamut; and displaying display content formed by superposing the layers after color gamut mapping. The problem that the degree of beauty of UI layers may be reduced when the same color gamut mapping mode is adopted for the display content of all the frames in a terminal is solved. Different color gamut mapping modes are adopted for different layer types of layers in a terminal, a natural layer can get a more accurate color, a UI layer can get a brighter color, and the display effect of final display content is improved on the whole.

Description

technical field [0001] The present disclosure relates to the field of display technology, in particular to a color gamut mapping method and device. Background technique [0002] Color gamut refers to the method of encoding colors, and also refers to the sum of colors that a technical system can produce. For example, sRGB (standard Red Green Blue, standard red, green and blue) color gamut coding and NTSC (National Television Standards Committee, National (USA) Television Standards Committee) color gamut coding. [0003] There is a color gamut mapping method in the related art. When the user wishes to display more accurate colors, the display content is mapped to the sRGB color gamut for display; when the user wishes to display brighter colors, the display content is mapped to the NTSC color gamut for display. . Contents of the invention [0004] In order to solve the problem that the display effect of some pictures is poor when the same color gamut mapping method is used ...
