Electronic device and control method thereof

Abstract

The invention discloses an electronic device and a control method thereof. The method comprises the steps of: obtaining a current color gamut mode in a plurality of color gamut modes of the electronic device, wherein the plurality of color gamut modes include a first color gamut mode, a second color gamut mode and a third color gamut mode; according to the current color gamut mode, a screen color gamut of the electronic device and a target color gamut of a pattern to be displayed, determining the practical color gamut corresponding to the current color gamut mode; when the current color gamut mode is the third color gamut mode, determining the practical color gamut under the third color gamut mode according to points arranged on lines between a plurality of summits of the practical color gamut of the first color gamut mode and a plurality of corresponding summits of the practical color gamut of the second color gamut mode, whose color errors are ranged from 1.5 to 3.0; and carrying out color gamut conversion on the pattern to be displayed according to the practical color gamut corresponding to the current color gamut mode, and displaying the pattern to be displayed. In this way, the plurality of color gamut modes are selectable, and the pattern to be display can be better reproduced.

Description

technical field [0001] The present invention relates to an electronic device and a control method thereof, in particular to an electronic device with multiple color gamut modes for selection and a control method thereof. Background technique [0002] Color gamut refers to the range of color expression, which can be divided into two types: device color gamut and pattern color gamut. Among them, the device color gamut refers to the maximum color range that can be represented by the device itself (such as a monitor) or by the device on a certain medium (such as a printer on printing paper); the pattern color gamut refers to a specific pattern or a set of colors. The range of colors that a pattern (such as a slideshow or a video) contains. [0003] Usually, the range of the device color gamut is smaller than the range of the pattern color gamut, resulting in dark or unsaturated colors when the device displays the pattern. Therefore, it is necessary to determine a new color gamu...

Problems solved by technology

[0004] However, when the existing equipment converts the color gamut of the pattern, it usually adopts a uniform method, for example, the method of obtaining the color range with accurate color locus is adopted. Obviously, this color gamut conversion method is suitable for concentrated color distribution. And patterns with obvious changing trends, and when this method is used for patterns with scattered color distribution and large formation areas, it will cause color distortion of patterns with scattered color distribution and large formation areas
