Problems solved by technology

[0003] However, for videos in standard definition and lower resolution formats, low definition, poor contrast, and lack of image details are common on 4K screen displays. Even if the display screen is high resolution, it is limited by the resolution of the signal itself , the picture quality is still relatively poor

Embodiment 1

[0020] according to figure 1 As shown, a processing method of ultra-high-definition video is provided, and the method comprises the following steps:

[0021] A. Receive each standard-definition video frame, and obtain the first enhanced image I after enhanced processing RGB ;

[0022] B. Obtain the relative brightness value of each frame of image after the enhancement processing; according to the relative brightness value, obtain the enhancement adjustment coefficient;

[0023] C. According to the first enhanced image I RGB and the enhancement adjustment coefficient to obtain the second enhanced image I FINAL ;

[0024] D. The second enhanced image I FINAL After two or more stages of conversion processing, the amplified ultra-high-definition video signal is obtained.

[0025] Specifically, the first enhanced image I is obtained after the enhancement processing RGB , including: converting the standard definition video frame to the HIS space, and first enhancing the I com...

Embodiment 2

[0043] The present invention also provides a processing system for ultra-high-definition video, and the system includes the following processing units:

[0044] The first enhancement unit is used to receive each standard-definition video frame, and obtain the first enhanced image I after enhancement processing RGB ;

[0045] An adjustment coefficient obtaining unit, configured to obtain the relative brightness value of each frame of image after the enhancement process; obtain the enhancement adjustment coefficient according to the relative brightness value;

Abstract

The invention provides an ultra-high-definition video processing method and system. The ultra-high-definition video processing method comprises the following steps: receiving each standard-definitionvideo frame, and obtaining a first enhanced image ISGB after enhancement processing; obtaining a relative brightness value of each frame of image after enhancement processing; obtaining an enhanced adjustment coefficient according to the relative brightness value; obtaining a second enhanced image IFINAL of each pixel point according to the first enhanced image ISGB and the enhancement adjustmentcoefficient; and performing two-stage or multi-stage conversion processing on the second enhanced image IFINAL to obtain an amplified ultra-high-definition video signal. According to the finally obtained ultra-high-definition video image, the video definition is far higher than the initial video definition, and the color is brighter, and the image details are more obvious, and extremely high visual experience is obtained.

Description

technical field [0001] The present invention relates to the technical field of ultra-high-definition video processing, in particular, to a method and system for processing ultra-high-definition video. Background technique [0002] With the development of science and technology and the advent of the era of large screens, traditional high-definition resolution images can no longer meet the increasing visual needs of the public. Compared with high-definition video, ultra-high-definition video has many advantages. It has higher resolution and larger data volume. The color allows the audience to get a more immersive feeling. The general promotion and application of ultra-high-definition resolution screens represented by 4K screens on LCD TVs has become the mainstream of the broadcasting media industry and has become a hot spot for current development. [0003] However, for videos in standard definition and lower resolution formats, low definition, poor contrast, and lack of ima...
