Embodiment Construction

[0047] It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

[0048] refer to figure 1 , figure 1 It is a schematic flowchart of a preferred embodiment of the image processing method of the present invention. The image processing method provided by the present invention includes step S10 to step S50. Each step is described in detail below.

[0049] Step S10, converting the YCbCr data of the input image into the HSI color space, the HSI color space presets several color regions formed by dividing by several isohue lines, and several color regions formed by dividing by several iso-saturation curves in each color region. iso-saturation regions, and the control points formed by the intersection of each iso-saturation curve with the iso-hue line;

[0050]In this embodiment, under the HSI color model, the model uses three dimensions of hue H, saturation S and brightness I to repre...

Abstract

The invention discloses a method and device for processing an image. The method for processing the image comprises the steps that the YCbCr data of the input image are converted to an HSI color space, the saturability of a control point corresponding to a primary saturability area and the saturability of a control point corresponding to a secondary saturability area are adjusted by analyzing the number of pixel points in all equisaturation areas in color areas in the HSI color space, and therefore a dynamic saturability curve is obtained; finally, the saturability of each pixel point of the image is adjusted according to the dynamic saturability curve, and therefore the image is adjusted. Due to the fact that area division is carried out on the colors of the image, when the saturability of each pixel point of the image is adjusted according to the dynamic saturability curve, the saturability increment gain value of the control points in equisaturation areas corresponding to a primary saturation grade is increased, the saturability increment gain value of the control points in equisaturation areas corresponding to a secondary saturation grade is reduced, and therefore primary color saturation is improved, and the frame color is layered. Then, the frame display effect is improved.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an image processing method and device. Background technique [0002] With the improvement of people's living standards, the pursuit of higher and higher picture display effects of electronic products. In the prior art, in order to improve the display effect of the picture, image processing is usually performed when the picture is displayed. In the process of image processing, in order to make the color display more vivid, it is usually necessary to adjust the saturation of the image. In the prior art, when adjusting the saturation of an image, preset saturation parameters are used to adjust the saturation of each point on the image. Since the adjustment is not divided into regions according to the image itself, the screen of the adjusted image The display effect is poor. Contents of the invention [0003] The main purpose of the present invention is to provid...
