Abstract

The embodiment of the present invention discloses a method for setting adaptive backlight control of picture content, which belongs to the field of communication technology, and includes: calculating the distortion volume of the CABC picture of the picture sample relative to the picture sample, and the CABC picture is the picture sample according to the preset Set the step size to carry out different CABC degree processing and mark the CABC picture of the target picture, calculate the mathematical expectation value of the distortion volume, obtain the critical expected value of the acceptable distortion volume, and obtain the critical expected value of the acceptable distortion volume corresponding to the picture to be processed, according to the obtained The acceptable distortion volume critical expectation value determines the target content adaptive backlight control degree of the picture to be processed, and sets and displays the picture to be processed according to the target content adaptive backlight control degree. The embodiment of the invention also discloses an electronic device and a computer-readable storage medium, which can reduce power consumption when performing CABC setting on pictures.

Description

technical field [0001] The invention belongs to the field of image technology, and in particular relates to a setting method for adaptive backlight control of picture content, an electronic device and a readable storage medium. Background technique [0002] The screen is an important component of the human-computer interaction interface in the mobile terminal. People's requirements for color and information content continue to increase, making the power consumption of the screen device one of the important reasons that affect battery life. Using Content Adaptive Backlight Control (CABC, Content Adaptive Backlight Control) can effectively reduce screen power consumption. [0003] At present, the very important basis for judging the degree of CABC technology activation on mobile terminals is whether the degree will cause image distortion. Specifically, a fixed threshold for enabling the technology is preset. The determination of the threshold is intuitively determined by the h...
