It should be noted that the steps shown in the flow chart of the accompanying drawings can be executed in a computer system such as a set of computer-executable instructions, and , although a logical order is shown in the flowcharts, in some cases the steps shown or described may be performed in an order different from that shown or described herein.

Fig. 1b is a schematic flowchart of an image display method according to an embodiment of the present application. As shown in Fig. 1b, the method includes the following steps:

Step S102, obtaining the identification in the 3D image to be displayed, wherein the identification is used to indicate the 3D format of the 3D image to be displayed; wherein, the 3D image to be displayed includes but is not limited to: an image that achieves a 3D stereoscopic viewing effect based on an external wearable device , and can also display images for glasses-free 3D (for example, glasses-free 3D display terminals, which include but are not limited to glasses-free 3D TVs, glasses-free 3D mobile phones, etc.).

Wherein, the above-mentioned identification may be carried in the current first image or the second image, wherein the first image and the second image are used to construct the 3D image to be displayed. The meaning of the above-mentioned "carried in" includes but is not limited to: embedding the above-mentioned logo into the first image or the second image, for example, adding the above-mentioned logo to the first image or the second image by adding a watermark, in order to avoid affecting For viewing effect, the above logo can be set in the top corner area of the first image or the second image, for example, in one of the upper left corner, upper right corner, lower left corner and lower right corner. The above-mentioned signs include but are not limited to icons or pictures, numbers, character strings, color blocks, etc. Wherein, the above-mentioned icon or picture may represent a combination of color blocks with a resolution smaller than a preset threshold, the combination of color blocks is composed of a plurality of color blocks arranged in a certain order, and the colors of adjacent color blocks are different. For example, the above identification is a picture with a resolution of 6*30.

As an optional embodiment, the at least one color includes: colors of different regions arranged at intervals in at least one preset region. In an optional embodiment, in order to avoid mutual interference during image processing, black may be inserted between different colors or the same color in at least one color, that is, different areas are separated by areas of black color.

Take the above logo as an example. The icon is a picture with a resolution of 6*30. It is mainly composed of three squares of the same size: pure red, pure green, and pure blue. Black squares can be added in the middle to reduce image processing. Mutual interference in the process, as shown in Figure 2, Figure 3, and Figure 4, the arrangement order of red, green, and blue squares corresponds to different 3D formats, for example, the color combination shown in Figure 2 corresponds to the format 2DPZ, and the color shown in Figure 3 The format corresponding to the combination is the left and right format, and the format corresponding to the color combination shown in Figure 4 is the top and bottom format. For the convenience of description, the numbers in the boxes in Fig. 2, Fig. 3 and Fig. 4 represent colors, for example, 1 represents red, 2 represents black, 3 represents green, and 4 represents blue.

For example, the above identification can be obtained in the following ways: detecting the color of at least one preset area in the first image and/or the second image to obtain at least one color; judging whether at least one color is the same as the preset color combination, and When the combination of colors and preset colors is the same, at least one color is determined to be the above-mentioned logo. Wherein, the preset color combinations are in one-to-one correspondence with the 3D formats, that is, different preset color combinations correspond to different 3D formats. Wherein, the aforementioned preset areas include, but are not limited to: square areas, circular areas, etc. of different colors.

Wherein, when detecting the color of the above-mentioned at least one preset area, the pixel values of the above-mentioned preset area can be averaged, and the color of the preset area can be determined according to the average value, and other methods can also be used, for example, considering the image There may be interference at the edge, which affects color recognition. Therefore, the RGB average value of pixels in a central area can be specified as the basis for determining the color, or the RGB value of the central point pixel in at least one area can be detected, and at least one color can be determined based on the RGB value. The color of the preset area. When using the central area to determine the color of the preset area, the central area is smaller than its corresponding preset area.

Wherein, when judging whether at least one color is the same as the preset color combination, it can be expressed as judging whether the color type and/or arrangement order are the same as the preset color combination, specifically, it can be determined in the following manner: judging each of the at least one color Whether the color and the arrangement order of each color are the same as those in the preset color combination.

Wherein, whether at least one color is the same as the preset color combination can be judged in the following manner, but not limited thereto: judging whether there is a preset color combination corresponding to at least one color in the preset set, wherein, when the judgment result indicates that there is, Then it is determined that at least one color is the same as the preset color combination, and different preset color combinations in the preset set correspond to different 3D formats. In an optional embodiment, when the judgment result indicates that there is no preset color combination corresponding to at least one color in the preset set, it is determined that the current display device displays data in a two-dimensional 2D format.

Step S104, determine the 3D format of the 3D image to be displayed according to the identifier. As mentioned above, there is a correspondence between the logo and the corresponding 3D format. Based on this, step S104 can determine the 3D format of the 3D image to be displayed according to the logo, so as to display the 3D image to be displayed in a correct manner.

For example, after a display device such as a naked-eye 3D TV or an advertising machine starts to play a video or receives a video signal (for example, an HDMI signal), it continuously collects the three square positions of red, green, and blue in the corresponding icon in the upper right corner of the display screen. For the center pixel point, judge the R, G, and B values of these three points to get the corresponding color. When the position and color of the three points are completely consistent with any of the previously given icons, it means recognition When the corresponding 3D format is reached, the display device will automatically switch to the corresponding image combination mode (play mode) to display the correct 3D picture, and continue to collect pixel information. When the pixel information no longer conforms to any When in 3D format, the display device automatically switches to 2D mode.

Step S106, displaying the 3D image to be displayed according to the 3D format.

Optionally, in order to ensure the viewing effect, when displaying the above-mentioned 3D images to be displayed, the above-mentioned identification can be hidden or deleted. For example, before displaying the 3D images to be displayed according to the 3D format, the following steps can be performed: Displaying a third image and a fourth image in a two-dimensional 2D format of a 3D image, wherein one of the images in the third image and the fourth image carries a logo; determining the depth of the 3D image to be displayed based on the third image and the fourth image Depth Map: determining an output 3D image according to the depth map and a designated image, wherein the designated image is an image that does not carry a logo among the third image and the fourth image.

It should be noted that, the third image and the fourth image may respectively correspond to the above-mentioned first image and the second image, or may be images different from the first image and the second image. For the former, the third image is the first image, the fourth image is the second image and the fourth image, and the first image and the second image; for the latter, for example, the third image and the fourth image are specially processed The special processing includes but is not limited to: processing such as edge noise removal, and the first image and the second image are initial images, that is, images that have not undergone special processing.

Taking naked-eye 3D TV as an example, as shown in Figure 5a, the method for displaying 3D images includes the following processing steps:

Step S502, the TV signal processor in the naked-eye 3D TV decodes the image and recognizes the icon, and then informs the 3D image processor of the result;

Step S504, the 3D image processor separates the left and right images from the entire image, as shown in Figure 5b, and the right image is provided with a logo;

Step S506, the 3D image processor compares the left and right images to obtain a depth image, as shown in Figure 5c;

In step S508, the 3D image processor mixes the left image and the depth image, and then sends the image to a display screen with a grating to display a 3D image, that is, display a 3D image through the display screen, as shown in Figure 5d.

Herein, a depth map refers to an image or an image channel that contains information about distances to surfaces of scene objects from viewpoints. It is similar to a grayscale image, except that each pixel value is the actual distance from the sensor to the object. Usually the RGB image and the Depth image are registered, so there is a one-to-one correspondence between pixels.

Based on the above-mentioned characteristics of the depth map, the above-mentioned mark does not exist in the 3D image determined by using the above-mentioned depth map and the specified image, that is, the above-mentioned mark is deleted or hidden, which improves user experience.

It should be noted that the subject of execution of steps S102-S106 includes but is not limited to: a video playback terminal, and may also be an application in the video playback terminal, such as a player application.
