US 11,457,188 B2 · Method and system for adjusting white balance, and display

Abstract

The invention discloses a method and system for adjusting white balance, and a display, and belongs to the technical field of display. The method for adjusting the white balance is applied to the display, and comprises the following steps: identifying image information of a currently played frame image to be adjusted; obtaining a matched target color temperature value according to the image information; and adjusting a white balance parameter of the frame image to be adjusted according to the target color temperature value. According to the method disclosed by the invention, by identifying the image information of the currently played frame image to be adjusted, and obtaining the matched target color temperature value according to the image information, the white balance parameter of the frame image to be adjusted is automatically adjusted according to the target color temperature value, the purpose of correspondingly adjusting the white balance parameter of the currently played frame image contents in real time can be achieved, so that the sense of tableau of the image is more realistic, and the visual effect is enhanced.
