Embodiment Construction

[0024] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only some, not all, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the protection scope of the present invention.

[0025] The chromaticity diagram is a plane diagram represented by the color coordinates of the function expression v=f(u) of the blackbody locus in chromaticity. Such as figure 1 As shown, the chromaticity diagram is the CIE1931 chromaticity diagram. The CIE1931 chromaticity diagram uses the brightness parameter Y and the color coordinates (x, y) to describe the color. Each point on the arc curve of the CIE1931 chromaticity diagram is a variety of spectrum. T...

Abstract

The embodiment of the invention provides a brightness compensation value obtaining method, computer equipment and a computer readable medium, relates to the technical field of display, and can eliminate the brightness contrast phenomenon. The brightness compensation value obtaining method comprises the steps of obtaining a tone component, a saturation component and a lightness component of each pixel according to an input image; counting the number of high-saturation pixels and the number of low-saturation pixels according to the saturation component and the brightness component of each pixel; judging whether the input image meets a hue offset condition or not; if yes, calculating the brightness compensation value of the low-saturation pixel according to the low-saturation pixel in the input image; and for the high-saturation pixel in the input image, judging whether a gray scale transition condition is met or not, and if not, calculating to obtain a brightness compensation value of the high-saturation pixel.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a method for acquiring a brightness compensation value, computer equipment and a computer-readable medium. Background technique [0002] With the development of liquid crystal display technology, the traditional RGB (red, green and blue) three-color display technology can no longer meet the needs of high brightness and low power consumption of electronic products. Therefore, multi-color display technology has gradually developed. [0003] RGBW (red, green, blue and white) four-color display technology adds a white sub-pixel to the RGB three-sub-pixel structure to form an RGBW structure. The RGBW four-color display technology can effectively improve the light transmittance, brightness, and reduce power consumption of the liquid crystal display panel. Contents of the invention [0004] Embodiments of the present invention provide a method for acquiring a brightness comp...
