Abstract

An embodiment of the invention provides a method and a device for adjusting picture colors of electronic equipment. The method is applied to the electronic equipment; the electronic equipment comprises a display screen and a processor; the processor comprises a display processing unit (DPU); and the DPU acquires a to-be-displayed picture, acquires a target 3D lookup table used for adjusting the to-be-displayed picture according to the first color mode, maps colors of the to-be-displayed picture according to the target 3D lookup table to obtain an adjusted picture, and sends the adjusted picture to a display screen for display by the DPU. According to the method, the existing color mapping hardware in the DPU is reused for adjusting the colors of the picture, so that the problems of performance and power consumption when an existing software mode is used for adjusting the color of the video are solved, the color of the high-resolution long video can be adjusted in real time, and the power consumption of the electronic equipment is not increased.

Description

technical field [0001] The present application relates to the technical field of image processing, and in particular to a method and device for adjusting screen color of an electronic device. Background technique [0002] With the development of mobile terminals, more and more users use mobile terminals to shoot and watch videos. A key factor affecting the video rendering effect is the color of the video, and different users have different perceptions and hobbies of colors. In order to To meet the needs of different users, it is hoped that the video can be color-graded differently to meet the different needs of users, and the video can be equipped with movie special effect colors through color-grading. [0003] In traditional technology, only various short video software has the color correction function. Short video software refers to software that can shoot and play short videos, and short videos are usually only 5 seconds to 5 minutes. Commonly used short video software ...
