Embodiment Construction
[0025] The present invention will be described in detail below in conjunction with the accompanying drawings and embodiments.
[0026] refer to figure 1 , figure 1 It is a schematic flowchart of an embodiment of the image color enhancement method of the present invention. Such as figure 1 As shown, the image color enhancement method in this embodiment includes the following steps:
[0027] Step S11: Convert the RGB values of the input image to HSV values, and extract the original saturation.
[0028] Specifically, the input image is converted from the RGB color gamut to the HSV color gamut through color gamut conversion. Both the RGB color gamut and the HSV color gamut have their own corresponding coordinate systems, so that the RGB color gamut of each pixel in the RGB color gamut coordinate system of the input image Values are converted to HSV values in the HSV gamut coordinate system, and then the original saturation of the input image is extracted. Among them, RG...

The present invention discloses an image color enhancement method, a display device and a storage device. The method comprises: converting a RGB (Red, Green, Blue) value of an input image to an HSV (Hue ,Saturation, Value) value, and extracting an initial saturation; regulating a selected saturation enhancement curve, and obtaining a final saturation curve, wherein the regulation comprises: regulating curve sections of slope absolute values exceeding a preset value, reducing the slope absolute value of the curve sections, and reducing a saturation difference corresponding an adjacent pixel; searching a final saturation curve according to the initial saturation, obtaining a corresponding final initial saturation, and obtaining an HSV value of the input image after color enhancement; and converting the HSV value after color enhancement to the RGB value to perform output display. According to the mode mentioned above, problems can be solved that an image generates color image anomaly and image quality is influenced caused by suddenly changed and increased saturation differences of part of adjacent pixels of an image after color enhancement, the color enhancement effect of an image is improved, and generation of image anomaly is reduced.
Description
technical field [0001] The invention relates to the technical field of image display, in particular to an image color enhancement method, a display device and a storage device. Background technique [0002] With the improvement of people's quality of life, people have higher and higher requirements for the image quality of image display panels, and the panels are all designed in the direction of high resolution and high saturation. But even so, the displayed image still cannot meet the requirements of some users for the vividness of the picture quality. As a result, color enhancement technology has emerged. However, the existing color enhancement technology can improve the vividness of the picture quality and meet the user's requirements to a certain extent, but after the color enhancement, there will be obvious color mutation (picture difference) phenomenon, which will affect the picture quality. Contents of the invention [0003] The invention provides an image color e...
