Embodiment Construction

[0047] Embodiments of the present application provide an image rendering method and device, a computing device, and a display device, so as to improve image rendering accuracy.

[0048] see figure 1 , an image rendering method provided in an embodiment of the present application, comprising:

[0049] S101. Convert the image data to be displayed into N discrete points for representing the correspondence between grayscale and brightness according to the correspondence between grayscale and brightness;

[0050] Wherein, N is an integer greater than or equal to 1.

[0051] For example, N equals 256.

[0052] The correspondence between the gray scale and the brightness is preset. For example, the corresponding relationship between grayscale and brightness is shown in the following formula:

[0053] Lum=Lmax*(r / Gray)^γ

[0054] in,

[0055] r represents the grayscale value;

[0056] Lum represents the brightness corresponding to the grayscale r;

[0057] Lmax represents the ...

Abstract

The present application discloses an image rendering method and device, a computing device, and a display device, which are used to improve the image rendering accuracy. An image rendering method provided by the present application includes: converting image data to be displayed into N discrete points used to represent the corresponding relationship between gray levels and brightness according to the corresponding relationship between gray levels and brightness; Interpolate the N discrete points to obtain M discrete points; wherein, M is greater than N; perform rendering calculation on the brightness information of the M discrete points to obtain the rendered brightness information; according to the correspondence between the gray scale and the brightness relationship, and convert the rendered luminance information into corresponding grayscale information.

Description

technical field [0001] The present application relates to the field of image technology, and in particular to an image rendering method and device, computing equipment, and display equipment. Background technique [0002] With the continuous development of science and technology, more and more electronic devices with display functions are widely used in people's daily life and work, which brings great convenience to people's daily life and work, and has become an indispensable essential tool. [0003] The display displays image pixels through the display panel. In the organic light-emitting display panel, the improvement of resolution is limited due to the evaporation process and the matching of pixel life. In order to improve the resolution, an image rendering method is generally used to drive the panel pixels of the display panel to display the image pixels of the image information to be displayed. Image information after rendering calculations is affected by calculation...
