Embodiment Construction

[0042] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments.

[0043] like figure 1 Shown is a schematic flow chart of an image enhancement method according to an embodiment of the present invention, and the image enhancement method includes the following steps:

[0044] Step 101, converting the original image from red, green, blue RGB color space to hue, saturation, brightness HSI color space;

[0045] Step 102, keeping the hue component unchanged, respectively performing enhancement processing on the brightness component and the saturation component to obtain a processed image;

[0046] Wherein, keeping the hue component unchanged can ensure that the processed image has no color shift.

[0047] Step 103, converting the processed image from HSI color space to RGB color space.

[0048] Existing display devices all use the RGB color space, so it is finally necessar...

Abstract

An image enhancement method, an image enhancement device and a display device are provided. The method comprises the following steps: transforming an original image from the RGB color space into the HSI color space (101); keeping the hue component unchanged, respectively performing the enhancement processing of the luminance component and saturation component to obtain a processed image (102); and transforming the processed image from the HSI color space into the RGB color space (103). The present invention transforms the image from the RGB color space into the HSI color space to perform enhancement processing, thus the defect of color loss can be avoided.

Description

technical field [0001] The present invention relates to the technical field of image enhancement, in particular to an image enhancement method, an image enhancement device and a display device. Background technique [0002] During the acquisition process, the image may be affected by factors such as the dynamic range of the imaging device and the intensity of ambient light, resulting in low image contrast, unclear image information, color distortion, and insufficient clarity of the outline or boundary information of the target, etc. This phenomenon brings difficulties to human visual observation and machine analysis and processing, so it is necessary to enhance the image. [0003] Image enhancement refers to a processing method that highlights certain information of an image according to specific needs, and at the same time weakens or removes some unnecessary information. It is the most basic means of image processing, and it is often the preprocessing process of various ima...
