[0047] The following describes the specific embodiments of the present disclosure in detail with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only used to illustrate and explain the present disclosure and are not intended to limit the present disclosure.

[0048] Figure 1 FIG. 1 is a flow chart of an image display method according to an exemplary embodiment of the present disclosure. Figure 1 As shown, an embodiment of the present disclosure provides an image display method, which can be applied to an electronic device, wherein the electronic device can be a device with an image display function such as a projection device or a display screen. The image display method can include the following steps.

[0049] In step 110 , the current sight angle of the user's eyes relative to the display area is obtained.

[0050] Here, the display area refers to the area formed by the electronic device for displaying images. When the electronic device is a display screen, the display area may refer to the image display area of the display screen. When the electronic device is a projection device, the display area may refer to the image display area formed by the projection device on the projected plane (wall / screen).

[0051] Figure 2 Schematic diagram of the sight angle provided according to an exemplary embodiment of the present disclosure. Figure 2As shown, the current sight angle may refer to the angle between the line connecting the user's eyes and the center point of the display area and the horizontal line at the current moment. This angle reflects changes in the user's field of view. The sight angle of the user's eyes relative to the display area is related to the user's spatial position. When the user's position changes, the user's current sight angle changes, thereby causing a change in the user's field of view.

[0052] Figure 3 FIG. 1 is a schematic diagram of a sight angle provided according to another exemplary embodiment of the present disclosure. Figure 3 As shown, point L is the user's eye, and plane JKMN is the display area. The current sight angle may refer to the angle between the line connecting the user's eye and each vertex of the display area and the display area. For example, Figure 3 , the current sight angle includes the angle between vector LN and display area JKMN, the angle between vector LM and display area JKMN, the angle between vector LK and display area JKMN, and the angle between vector LJ and display area JKMN. It should be understood that vectors LN, LM, LK, and LJ constitute the field of view of the user's eyes. When the position of the user's eyes changes, the field of view also changes.

[0053] It is worth mentioning that Figure 3 The rectangular shape of the display area JKMN is only used to illustrate the current viewing angle and does not limit the shape of the display area. For example, the shape of the display area can be square, circular, triangular or other regular or irregular shapes.

[0054] Figure 4 FIG. 1 is a flow chart of determining the current sight angle according to an exemplary embodiment of the present disclosure. Figure 4 As shown, in some embodiments, in step 110, obtaining the current sight angle of the user's eyes relative to the display area may include the following steps.

[0055] In step 111 , the user is photographed by a camera device to obtain a photographed image.

[0056] Here, the camera device may be a camera mounted on the electronic device. For example, when the electronic device is a display screen, the camera device may be a camera mounted on the display screen. Of course, the camera device may not be mounted on the electronic device. For example, when the electronic device is a projection device, the camera device may be mounted near the display area to track the user's eyes.

[0057] In step 112, first position information of the user's eyes relative to the camera device is obtained based on the position information and depth information of the user's eyes in the captured image.

[0058] Here, after acquiring the captured image, the captured image can be used as input to a trained neural network model to obtain position information and depth information of the user's eyes in the captured image. The neural network model can be obtained by training a machine learning model based on training samples annotated with the position and depth information of the eyes. Of course, in some embodiments, the user can also be photographed using a binocular camera, and then target detection can be performed on the captured image to determine the first position information of the user's eyes relative to the camera device.

[0059] In step 113, based on the relative position relationship between the camera device and the display area and combined with the first position information, the current sight angle of the human eye relative to the display area is obtained.

[0060] Here, since the positions of the camera device and the display area are fixed in space, after obtaining the first position information, the first position information of the user's eye can be converted into the position of the user's eye relative to the display area based on the relative position relationship between the camera device and the display area, and then the current viewing angle of the user's eye relative to the display area can be determined based on this position.

[0061] When the display area is a display screen, the electronic device can use spatial positioning technology to obtain the positional relationship between the display screen and the camera device. For example, the spatial positions of the display screen and the camera device can be obtained using WiFi positioning technology. When the display area is a projection area formed by a projection device, the position of the projection device can be first determined. Then, based on the position of the projected plane (wall / screen) and the position of the projection device, the position of the display area can be determined, thereby determining the relative positional relationship between the camera device and the display area.

[0062] In some embodiments, when the display area is the projection area of a projection device, second position information of the user's eye relative to the projection device can be obtained based on the relative positional relationship between the camera and the projection device, combined with the first position information. The current viewing angle of the user's eye relative to the display area is then obtained based on this second position information and the positional relationship between the projection device and the projected surface.

[0063] Here, the second position information refers to the position of the user's eyes in the reference coordinate system where the projection device is located. In this reference coordinate system, based on the positional relationship between the projection device and the projected plane, the position of the projection area projected by the projection device on the projected plane is obtained, thereby determining the current viewing angle of the user's eyes relative to the display area in the reference coordinate system.

[0064] In some embodiments, the projection device may measure the projected plane based on a time-of-flight sensor provided on the projection device, thereby determining the relative positional relationship between the projected plane and the projection device.

[0065] In step 120, a target display image matching the current sight line angle is determined according to the current sight line angle, wherein the image content of the target display image is a sub-image in the original image matching the current sight line angle.

[0066] Here, different viewing angles may correspond to different display images. After obtaining the current viewing angle, the corresponding target display image may be determined based on the current viewing angle. The target display image determined based on the current viewing angle is a sub-image on the original image that matches the current viewing angle.

[0067] It should be understood that the current viewing angle of the user's eyes relative to the display area corresponds to the current visual range of the area visible through the display area. In the original image, each sub-image corresponds to the image content visible through the display area at a given viewing angle. When the current viewing angle of the user's eyes relative to the display area changes, the corresponding target display image will also change.

[0068] In some embodiments, a target display image matching the current viewing angle can be determined based on the current viewing angle and the mapping relationship between the viewing angle and the sub-image in the original image; wherein the mapping relationship includes each different viewing angle corresponding to a sub-image of the original image at that viewing angle.

[0069] Here, for the original image, images of the target object (including scenery, people, and objects, etc.) contained in the original image can be captured at different sight angles to obtain multiple sub-images, and then the corresponding sight angle is matched for each sub-image, and a mapping relationship between the sight angle and the sub-image is established. After obtaining the current sight angle of the human eye relative to the display area, the corresponding sub-image can be searched in the mapping relationship based on the current sight angle to obtain the target display image. In other embodiments, the original image can be a panoramic image. For example, a panoramic image containing the target object can be captured, and then corresponding sight angles can be matched for different sub-image areas of the panoramic image. After determining the current sight angle of the user's eye relative to the display area, the corresponding sub-image can be determined in the panoramic image based on the current sight angle, and the sub-image is determined as the target display image. It should be understood that each different sight angle corresponds to an original sub-image at that sight angle. This can be understood as, in a large-scale image containing the target object, the position of the user's field of view in the large-scale image is determined based on the current sight angle, and the image at that position is the sub-image that matches the current sight angle.

[0070] It should be understood that at the current viewing angle Figure 2 When the angle between the line connecting the user's eyes and the center point of the display area and the horizontal line is shown, the position of the field of view in the large-scale image can be determined based on the preset field of view and the angle, thereby determining the target display image. The preset field of view can be the visual range of different groups of people statistically analyzed.

[0071] The current viewing angle is Figure 3 In the case of the angles between the vectors LN, LM, LK and LJ and the display area shown, the surface JKMN can be used as the user's field of view. Combined with the angles between the vectors LN, LM, LK and LJ and the display area, the position of the user's field of view in the large-size image can be determined, thereby determining the target display image.

[0072] In step 130 , a target display image is displayed on the display area.

[0073] Here, after determining the target display image, the target display image is displayed on the display area. Specifically, when the display area is a display screen, the target display image is directly displayed on the display screen. When the display area is an image display area projected by a projection device, the projection device is controlled to project the target display image so that the target display image is displayed on the display area.

[0074] It should be understood that the image display method provided by the embodiments of the present disclosure can detect the current viewing angle of the user's eyes relative to the display area in real time, and then display different target display images based on the current viewing angle, thereby creating the effect that the image viewed by the user on the display area is a three-dimensional image. For example, if the display area is understood as a window and the original image is understood as the scenery outside the window, the angle of the same scenery that the user can see through the window will be different for different viewing angles, thereby creating a three-dimensional effect.

[0075] Therefore, by obtaining the current viewing angle of the user's eyes relative to the display area and displaying the corresponding target display image on the display area according to the current viewing angle, sub-images of the original image at different viewing angles can be displayed as the user's viewing angle changes, creating a three-dimensional display effect to improve the user experience when using the display device.

[0076] In some embodiments, the display area may include a first display layer and a second display layer, wherein the second display layer is superimposed on the first display layer. In step 130, displaying the target display image on the display area may include:

[0077] The background image is displayed in the first display layer, and the foreground image is displayed in the second display layer, so that the background image and the foreground image are superimposed to form a three-dimensional effect.

[0078] Here, the first display layer and the second display layer can each be understood as an independent video player. The target display image displayed on the first display layer is the background image, and the target display image displayed on the second display layer is the foreground image. The background image and the foreground image are superimposed to create a three-dimensional effect. The foreground image can be fixed or changed with the current viewing angle. For example, the corresponding foreground image can be determined based on the current viewing angle.

[0079] Figure 5 Schematic diagram of a background image and a foreground image provided according to an exemplary embodiment of the present disclosure. Figure 5 As shown, in Figure 5 In part (a), the background image is the first scene image at the first sight angle, and the foreground image is the first foreground image, which is the window. The window and the first scene image are superimposed to form a three-dimensional effect. Figure 5In part (b), the background image is a second scene image at a second viewing angle, and the foreground image is a second foreground image, which is a window. When the position of the user's eyes changes, the viewing angle relative to the display area changes from the first viewing angle to the second viewing angle, causing the scene image in the background image to change from the first scene image to the second scene image. In this case, the second foreground image can be the first foreground image. That is, when the viewing angle of the user's eyes relative to the display area changes, the scene image outside the window changes with the change in viewing angle, creating a dynamic three-dimensional effect.

[0080] It is worth noting that in actual application scenarios, the display area may include not only the first display layer and the second display layer, but also at least three display layers. For each display layer, different display images can be designed according to the positional relationship of the display layer in at least three display layers to achieve a better three-dimensional display effect.

[0081] Below, combined with the attached Figure 6 The principle of how the first display layer and the second display layer present a three-dimensional effect is described in detail.

[0082] Figure 6 FIG. 1 is a schematic diagram of a first display layer and a second display layer superimposed to form a three-dimensional effect according to an exemplary embodiment of the present disclosure. Figure 6 As shown, surface ZBVX is the original image, surface GHIJ is the first display layer, and surface CDEF is the second display layer. Point A is the position of the human eye. When point A changes, the visible area formed by the intersection of the ray formed by point A and points C, D, E, and F with the first display layer GHIJ will be located at a different position on the original image ZBVX, resulting in a different sub-image. Because the first and second display layers are on the same plane, the background image changes. Therefore, by tracking the user's eyes, the image content displayed on the first display layer can be adjusted in real time according to the user's line of sight, so that a 3D effect can be presented regardless of the user's viewing angle.

[0083] In some embodiments, the image display method can also obtain the distance between the user's eyes and the display area, adjust the display depth of the background image according to the distance, obtain the adjusted background image, and display the adjusted background image in the first display layer and the foreground image in the second display layer.

[0084] Here, based on the principle that objects appear larger when they are closer than they are smaller, the size of the background image seen by the user will also vary depending on the distance between the user's eyes and the display area. This is especially true for objects that are closer to the background image, as the distance between the user and the display area has a greater impact on the image. Display depth can be understood as the depth of field of the target object within the background image. The closer the distance between the user's eyes and the display area, the shallower the depth of field of the target object within the background image. The farther the distance between the user's eyes and the display area, the deeper the depth of field of the target object within the background image.

[0085] It should be understood that adjusting the display depth of the background image according to the distance between the human eye and the display area can be adjusting the display depth differently according to the depth of each target object in the background image. For example, for the target object in the background image that is within the first depth range, the display depth is adjusted to the first display depth, and the target object that is within the second depth range is adjusted to the second display depth. The first depth range is smaller than the second depth range, and the first display depth is greater than the display depth. That is, the principle of display depth adjustment can be to make a large-scale adjustment for the target object in a closer depth range, and to make a smaller adjustment or no adjustment for the target object in a farther depth range. For example, in Figure 6 In the example, when point A approaches the display area CDEF, the background image of the first display layer in the display area CDEF is magnified, but the foreground image remains unchanged, presenting an effect that the user is approaching the foreground image.

[0086] Therefore, by adjusting the display depth of the background image according to the distance between the user's eyes and the display area, the image displayed in the display area can be changed according to the distance position of the user to display a better three-dimensional effect.

[0087] In some embodiments, the display area may further include a special effects layer located between the first display layer and the second display layer. When the first display layer displays the background image and the second display layer displays the foreground image, a special effects image may be displayed in the special effects layer so that the background display image, the foreground image, and the special effects image are superimposed to form a three-dimensional effect.

[0088] Here, the special effect image can be an image determined based on the scene of the background image and the foreground image to enhance the three-dimensional effect. For example, when the background image is a landscape image and the foreground image is a window, the special effect image can be a special effect image such as rain, snow, or fog produced based on the scene.

[0089] It should be understood that special effect images can also be determined based on the current viewing angle, with different special effect images displayed for different current viewing angles. The principle of determining special effect images based on the current viewing angle is the same as the principle of determining the target display image based on the current viewing angle, and will not be explained in detail here.

[0090] Thus, by displaying the special effect image in the special effect layer, the background image, the foreground image and the special effect image are superimposed to form a better three-dimensional effect.
