Problems solved by technology

[0003] In view of this, the purpose of this application is to provide an image display method, device, electronic equipment and readable storage medium, which calculates the actual value of the current frame image according to the maximum value of the primary color component and the average value of the primary color component in the current frame image. The target brightness reference value corresponding to the brightness, and then the target brightness reference value adjusts the backlight brightness, so as to effectively improve the problem of poor backlight control effect and poor display effect caused by the large deviation between the calculated brightness and the actual brightness of the frame image

Abstract

Embodiments of the present application provide an image display method, device, electronic equipment, and readable storage medium, which relate to the field of image display technologies. The method includes: obtaining the maximum value of the primary color components and the average value of the primary color components in the current frame image according to the three primary color components of each pixel in the current frame image to be displayed; performing weighted summation on the obtained above-mentioned values ​​to obtain a target brightness reference value ;According to the preset corresponding relationship between the brightness reference value and the pulse width modulation duty ratio, and the target brightness reference value, the target pulse width modulation duty ratio is obtained; the backlight brightness of the backlight module is adjusted by using the target pulse width modulation duty ratio , and display the current frame image. Therefore, adjusting the backlight brightness according to the target brightness reference value corresponding to the actual brightness of the current frame image can effectively improve the poor backlight control effect and poor display effect caused by the large deviation between the calculated brightness and the actual brightness of the frame image. good question.

Description

technical field [0001] The present application relates to the technical field of screen display, and in particular, to an image display method, device, electronic equipment, and readable storage medium. Background technique [0002] At present, the backlight control of a display device (for example, a liquid crystal television) generally first obtains the brightness of a frame image according to a brightness equation, and then adjusts the brightness of the backlight according to the brightness. Wherein, the brightness equation is: Y=0.30R+0.59G+0.11B. However, in some cases, there is a large deviation between the luminance calculated by the above method and the actual luminance of the frame image, which will lead to poor control effect of backlight luminance and poor display effect. For example, the R (red) component and G (green) component of a frame image are very small, and the B (blue) component is very large, and the actual brightness of the frame image is much greater...
