Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer and clearer, the present invention is further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
With the development of technology, playing display devices such as televisions, projectors and the like are also updated iteratively and quickly. In order to improve the viewing experience of users, many video images at present have 8K resolution, and 8K ultra-high definition resolution (7680 × 4320) is 16 times greater than 2K (1920 × 1080) resolution, and 4K (3840 × 2160) resolution, and the definition is 16 times greater than that of the blue-ray version. Due to the ultra-high definition resolution, people can be provided with the feeling of being personally on the scene when watching images, the 8K resolution television has quite excellent display effect, and each detail of the image can be clearly seen as if the person is living in front of the image in the case of watching Japanese worship and tour or watching sunflowers in a rural area. Even when moved very close, no pixel on the panel is visible. In addition, the position with the horizontal viewing angle of 100 ° is an optimal display environment in which the 360 ° panoramic display technology has not been proposed yet. Much more stimulating than viewing a horizontal viewing angle of only 55 ° at 2K, 4K resolution.
Research and research show that some middle and low-end playing devices sold on the market at present only support playing with 4K resolution, and most video images are 8K resolution at present, so that the quality of the images is improved, when a user obtains a code stream source with 8K resolution, the user cannot play the code stream source on the 4K support, and hardware of the playing device needs to be replaced, so that the video images with 8K resolution are played.
In order to solve the problems of the prior art, this embodiment provides a video image display method, and the present invention first obtains video data to be played, and determines original 8K image data corresponding to the video data to be played, where the original 8K image data may reflect a resolution of an image, and the image may be cut and synthesized through the resolution. Therefore, after original 8K image data are obtained, the original 8K image data are cut to obtain first 4K image data, then pixel value operation processing is carried out on the first 4K image data to obtain 2K image data, finally the 2K image data are combined to obtain second 4K image data, and the second 4K image data are decoded to obtain a display image to be displayed. Therefore, the invention can process the image with 8K resolution into the image with 4K resolution without replacing the hardware configuration, thereby displaying the image on the playing device supporting 4K resolution.
For example, if a video with 8K resolution needs to be played on a television supporting 4K resolution, video data to be played needs to be obtained first, original 8K image data corresponding to the video data to be played is determined according to the video data to be played, and the original 8K image data is cut to obtain first 4K image data; carrying out pixel value operation processing on the first 4K image data to obtain 2K image data; and merging the 2K image data to obtain second 4K image data, and decoding the second 4K image data to obtain a display image, wherein the resolution of the second 4K image data is 4K, so that a television supporting the 4K resolution can display the display image.
Exemplary method
The method for displaying video images in the embodiment can be applied to terminal equipment such as televisions, computers and the like. The terminal device has a display function, for example, a display screen is arranged on a television, and a video image can be played. In specific implementation, as shown in fig. 1, the method for displaying a video image in this embodiment includes the following steps:
step S100, video data to be played are obtained, and original 8K image data corresponding to the video data to be played are determined.
In specific implementation, since the video image data with the 8K resolution needs to be processed to obtain the image data with the 4K resolution for playing in this embodiment, the video image with the 8K resolution needs to be obtained first, the obtained video data to be played is stored in the CPU cache, and the video data to be played is read and decoded to obtain the original 8K image data.
And step S200, cutting the original 8K image data to obtain first 4K image data.
In specific implementation, because the image data with the 8K resolution needs to be processed into the image data with the 4K resolution in this embodiment, the original 8K image data needs to be cropped first to obtain the first 4K image data, but the cropped first 4K image data cannot be directly used for playing, so the first 4K image data needs to be obtained first, which is convenient for obtaining the image data that can be displayed on the playing device supporting the 4K resolution through the image processing subsequently.
In one implementation, as shown in fig. 2, the step S200 specifically includes the following steps:
step S201, acquiring position information of the original 8K image data;
step S202, averagely cutting the original 8K image data into four parts according to the position information of the original 8K image data to obtain first 4K image data.
In specific implementation, in this embodiment, the original 8K image data is clipped to obtain the first 4K image data, and during the clipping process, the clipping needs to be performed according to the position of the original 8K image data, so that the position information of the original 8K image data needs to be obtained first. A coordinate system is established in the pixel arrangement diagram of the original 8K image data, as shown in fig. 3, the X coordinate of the first pixel at the upper left corner is 1, the Y coordinate is 1, and so on, the X coordinate of the pixel at the lower right corner is 7680, and the Y coordinate is 4320, so that the position information of the original 8K image data can be represented as the image pixel coordinate (X, Y), and the corresponding pixel values R, G, and B can be represented as R (X, Y), G (X, Y), and B (X, Y). Since the original 8K image data needs to be cropped into the first 4K image data in this embodiment, the cropping is performed according to the position information of the original 8K image data, and as shown in fig. 4, the original 8K image data is cropped into four first 4K image data, which are named as 1-4K, 2-4K, 3-4K, and 4-4K, respectively, on average.
S300, performing pixel value operation processing on the first 4K image data to obtain 2K image data.
In specific implementation, since the second 4K image data is finally obtained by stitching the plurality of 2K image data, after the first 4K image data is obtained, the first 4K image data needs to be subjected to operation processing to obtain the 2K image data. In the operation process, algorithms such as compensation operation processing, boundary threshold operation processing and the like can be adopted, and in the embodiment, the 2K image is obtained by adopting pixel value operation processing.
In one implementation, as shown in fig. 5, the step S300 specifically includes the following steps:
step S301, acquiring position information of the first 4K image data;
step S302, determining a pixel value corresponding to the position information of the first 4K image data according to the position information of the first 4K image data;
step S303, determining a target position according to the pixel value;
and step S304, determining 2K image data according to the target position.
In specific implementation, since four first 4K image data are obtained after the original 8K image data are clipped, in this embodiment, 1 to 4K of the first 4K image data are selected as an example when the pixel value operation processing is performed on the first 4K image data. Firstly, the position information of 1-4K is determined to be (X-1, Y-1) according to a preset coordinate system, the corresponding pixel values of 1-4K are represented as R (X-1, Y-1), G (X-1, Y-1), B (X-1, Y-1), and similarly, the pixel values can be represented by changing to-2, -3, -4 during the processing of 2-4K, 3-4K and 4-4K. In order to obtain a more accurate pixel value, in this embodiment, a pixel value of any adjacent four pieces of position information is taken from 1 to 4K, and an average value of the pixel values of any adjacent four pieces of position information is taken to obtain a target pixel value, so that the target position is determined according to the target pixel value. For example, the pixel values of four adjacent position information at the upper left corner are taken from 1 to 4K, as shown in fig. 6, the four adjacent position information may be represented by (1,1), (2,1), (1,2), (2,2), the pixel values of the four adjacent position information may be represented by R (1,1), R (2,1), R (1,2), R (2,2), G (1,1), G (2,1), G (1,2), G (2,2), B (1,1), B (2,1), B (1,2), B (2,2), and the target pixel value obtained by averaging the pixel values may be represented by R (1-1, 1) + R (2,1) + R (1,2) + R (2,2))/4, G (1-1), 1-1) ═ G (1,1) + G (2,1) + G (1,2) + G (2,2))/4, and B (1-1 ) ═ B (1,1) + B (2,1) + B (1,2) + B (2,2))/4, and the corresponding target position can be determined to be (1-1 ) according to the target pixel value. After averaging the pixel values of any four adjacent position information in 1-4K, several target pixel values can be obtained, and since the position information of 1-4K is composed of (1,1) - (3840,2160), that is, 3840 × 2160 position information in total, 1920 × 1080 target position information can be obtained after grouping four position information into one group. As shown in fig. 7, image data corresponding to a target pixel value corresponding to a target position is acquired, and the image data is placed in the corresponding target position, so that 2K image data can be obtained.
S400, merging the 2K image data to obtain second 4K image data, and decoding the second 4K image data to obtain a display image for displaying.
In specific implementation, since the second 4K image data is finally required to be obtained and the second 4K image data is required to be played in the playing device in this embodiment, four pieces of 2K image data and position information corresponding to the 2K image data are required to be obtained, as shown in fig. 8, the four pieces of 2K image data are combined into one piece of 4K image data according to the position information corresponding to the 2K image data to obtain the second 4K image data, the second 4K image data is output to the rear end to be decoded, a display image is obtained, and the display image is output to the display of the playing device to be displayed.
In summary, in this embodiment, first, video data to be played is obtained, and original 8K image data corresponding to the video data to be played is determined, where the original 8K image data may reflect a resolution of an image, and the image can be cut and synthesized through the resolution. Therefore, after original 8K image data are obtained, the original 8K image data are cut to obtain first 4K image data, then pixel value operation processing is carried out on the first 4K image data to obtain 2K image data, finally the 2K image data are combined to obtain second 4K image data, and the second 4K image data are decoded to obtain a display image to be displayed. Therefore, the invention can process the image with 8K resolution into the image with 4K resolution without replacing the hardware configuration, thereby displaying the image on the playing device supporting 4K resolution.
