Detailed ways

The solution of the embodiment of the present invention is mainly: the VIDEO (video) layer and the OSD (On Screen Display, screen menu adjustment) layer respectively receive a total of two or more than two signals for 3D processing, and at least two signals after processing are processed. Channel signals are displayed on different areas of the same display screen of the display terminal at the same time, so as to improve the utilization rate of the large-screen display screen and enhance the user's entertainment effect.

In the present invention, the display terminal may be a large-screen TV, a computer or other display devices with a super-large display screen. The following embodiments are all illustrated with a large-screen TV, but are not limited to this situation.

As shown in Figure 1, a preferred embodiment of the present invention proposes an image display method, including:

Step S101, receiving at least two signals;

Step S102, performing 3D processing on the two signals at the VIDEO layer and the OSD layer respectively;

The TV set in this embodiment can process multiple signals, and display 3D images corresponding to each signal on the TV screen at the same time. The 3D images can be ordinary video images, or various application images, such as game content, etc. .

Corresponding to ordinary video images, the TV receives ordinary video signals, which are processed in the VIDEO layer of the TV; corresponding to application images, the TV receives application signals such as games, and the application signals are processed in the TV layer. OSD layer for processing.

Therefore, the at least two signals received by the television set in this embodiment may be at least two video signals respectively input to different VIDEO layers; or at least two application signals respectively input to different OSD layers; The video signal input to the corresponding VIDEO layer and the application signal input to the corresponding OSD layer.

That is to say, the television can process multiple video signals through different VIDEO layers, or process multiple application signals through different OSD layers, or process at least one video signal and At least one channel of the application-like signal finally achieves the effect of displaying different 3D images on the TV display screen.

Step S103, simultaneously displaying at least two channels of 3D-processed signals from the VIDEO layer and the OSD layer on predetermined different areas of the display screen of the display terminal.

After the VIDEO layer and OSD layer of the TV set perform corresponding 3D processing on at least two channels of signals received, they are fused and output to different designated areas on the display screen of the TV set for display, and different users can watch different images through 3D glasses. 3D effect.

Specifically, the solution of this embodiment will be described in detail below by taking the VIDEO layer of the TV set to process one video signal and the OSD layer to process one application signal as examples.

This embodiment considers that most commonly used single 3D image effects are processed for video signals, and there is no solution for 3D processing specifically for the OSD layer, because the OSD layer is often used to display control menus, volume, station numbers, etc. information. In this embodiment, the 3D processing of the OSD layer and the 3D processing of the VIDEO layer are fused together, and finally displayed together on the display screen of the TV, so as to achieve the effect of watching two 3D contents at the same time.

Among them, the display screen of the TV adopts a polarizing screen.

Firstly, the TV receives two signals, one is a 3D video signal, and the other is a 3D game application signal. The 3D video signal is processed at the VIDEO layer of the TV, and the 3D game application signal is processed at the OSD layer of the TV. And it is set that the 3D image processed by the VIDEO layer is displayed on the right end of the TV display screen, and the 3D image processed by the OSD layer is displayed on the left end of the TV display screen.

Among them, the processing flow of the VIDEO layer is: the 3D video signal entering the TV through each signal terminal of the TV first enters the image processing module of the TV, and in the image processing module, the horizontal and vertical resolution of the video image is changed by the SCALE module. rate, to compress the video image, the compression ratio can be half of the original image, that is, 1/2, or it can be compressed into other sizes, such as 1/4, 1/3 or other ratios, etc., for the convenience of users watch.

Taking the resolution of 1920*1080 as an example, the coordinates of the video image before being processed by the SCALE module are (0, 0, 1920, 1080), and after being compressed into half by the SCALE module, the coordinates of the video image become (960, 0, 960, 1080), that is, the row direction of the video image is reduced by half, and it is scheduled to be displayed on the right end of the display. Then, through the 3D processing module in the image processing module, the incoming video signals in different 3D formats are uniformly processed into signals in an interleaved format. The 3D video that is finally output to the display screen of the TV will be displayed on the right side of the screen, and the user can watch the 3D effect of the video through 3D glasses.

The processing flow of the OSD layer is: the 3D game signals of various applications enter the TV through each signal terminal of the TV, and first enter the OSD processing module of the TV. In the OSD processing module, the SCALE module changes the OSD game image. Horizontal and vertical resolution, the game image is compressed, the compression ratio can be half of the original image, that is, 1/2, or it can be compressed into other sizes, such as 3/4, 2/3, etc. (need to be compatible with the video The compression ratio of the image corresponds to) for the convenience of users to watch.

Taking the resolution of 1920*1080 as an example, the coordinates of the game image before being processed by the SCALE module are (0, 0, 1920, 1080), and after being compressed into half by the SCALE module, the coordinates of the game image become (0, 0, 960 , 1080), that is, the game image is scaled by half in the row direction, and is scheduled to be displayed on the left end of the display screen. Then, through the 3D processing module in the OSD processing module, the incoming game application signals in different 3D formats are uniformly processed into interleaved format signals. The 3D game image that is finally output to the display screen of the TV will be displayed on the left side of the screen, and the user can watch the 3D effect of the game through the 3D glasses.

In this embodiment, after the video signal and the game application signal are processed by their respective modules, the final display effect on the TV screen is shown in Figure 2. On the TV screen, two groups of different 3D contents will be displayed, 3D1 3D2 is common video content, and users can see two different 3D content at the same time through 3D glasses. For ultra-wide and super-large displays, users can focus on the half of the screen they want to see, enjoy their own 3D images without interference, and of course, can also pay attention to the 3D exciting scenes on the other half of the screen at the same time . Thus, the user's entertainment effect is increased.

It should be noted that, the above-mentioned regions on the display screen of the TV set for displaying different 3D images can be arranged in a left-right arrangement or a vertical arrangement as required. In the above-mentioned left-right arrangement and vertical arrangement, the images can be arranged symmetrically, or Can be arranged asymmetrically. For example, the two 3D processed signals from the VIDEO layer and the OSD layer can be displayed on the left half area and the right half area of the terminal display at the same time, or the two 3D processed signals from the VIDEO layer and the OSD layer The signals are simultaneously displayed on the upper and lower areas of the terminal display.
