Problems solved by technology

However, when the viewer looks sideways at the HVA liquid crystal display panel, the first thing the viewer can feel is the color shift and whitening of the skin color of the display screen.
If sub-pixel rendering (SPR) is performed on the display screen, it can improve the color cast and whitening of the skin color, but it will make the entire display screen feel grainy and affect the viewing experience of the viewer.
[0005] Therefore, there is a need for an image enhancement method for sub-pixel rendering for skin color to solve the color cast and whitening phenomenon of skin color in the display screen in the prior art

Embodiment Construction

[0074] The characteristics and spirit of the present invention are more clearly described through the detailed description of the following specific embodiments, and the scope of the present invention is not limited by the disclosed specific embodiments. On the contrary, the intention is to cover various modifications and equivalent arrangements within the scope of the appended claims of the present invention.

[0075] An image enhancement method provided by the present invention mainly performs sub-pixel rendering on the block containing skin color in the display screen of the display panel through the following six steps, so as to solve the color cast and whitening phenomenon of the skin color in the display screen in the prior art.

[0076] S1. Acquire the RGB color space of the pixels in the first frame.

[0077] S2. Convert the RGB color space of the pixels in the first picture to the HSV color space of the pixels in the second picture.

[0078] S3. Filter the HSV color ...

Abstract

The invention provides an image enhancement method and an image enhancement device. The image enhancement method includes the following steps: S1, obtaining the RGB color space of the pixels in the first picture; S2, converting the RGB color space of the pixels in the first picture into pixels in the second picture HSV color space; S3, filter the HSV color space of the pixel in the second picture through a preset value range; S4, according to the screening result of step S3, filter the pixel in the second picture Pixel binarization to form a third frame including a binary image; S5, mapping pixel blocks with a value of 1 in the third frame to the first frame to form a target pixel block; and S6 . Perform sub-pixel rendering on the target pixel block in the first picture according to the compensation parameter.

Description

technical field [0001] The present application relates to the technical field of image enhancement, in particular to an image enhancement method and an image enhancement device. Background technique [0002] Nowadays, while consumers are pursuing larger-sized liquid crystal display panels, they also require the liquid crystal display panels to have higher resolution and larger viewing angles. [0003] Mainstream liquid crystal display panels include: twisted nematic (TN) liquid crystal display panels, vertical alignment (vertical alignment, VA) liquid crystal display panels, and in-plane-switching (IPS) liquid crystal display panels. Among them, the viewing angle of the IPS liquid crystal display panel is the largest, and even the high-quality vertical alignment (HVA) liquid crystal display panel of the improved TN liquid crystal display panel cannot compete with it. [0004] By adjusting the timing control circuit (timing controller, TCON) in the HVA liquid crystal display...
