The embodiment of the invention discloses a setting method for picture content self-adaptive backlight control. Belonging to the technical field of communications, the method comprises the steps of calculating a distortion volume of a CABC picture of a picture sample relative to the picture sample, wherein the CABC picture is a CABC picture which is obtained by performing different CABC degree processing on a picture sample according to a preset step length and marking the picture sample as a target picture; calculating a mathematical expected value of the distortion volume; obtaining an acceptable distortion volume critical expected value; and obtaining an acceptable distortion volume critical expected value corresponding to the to-be-processed picture, determining a target content adaptive backlight control degree of the to-be-processed picture according to the obtained acceptable distortion volume critical expected value, and setting and displaying the to-be-processed picture 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 the power consumption when the CABC setting is carried out on the picture.
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...
