Description

[Technical field]

[0001] The present invention relates to the field of three-dimensional display technology, and in particular to a naked-eye 3D horizontal and vertical screen adaptive processing method with low interference and outstanding display effect. [Background Technology]

[0002] With the rise of short video content, vertical screen content has begun to increase. When naked-eye 3D technology is applied to smart display devices such as mobile phones and computers, it is necessary to consider that when users watch naked-eye 3D content on the device, horizontal and vertical screen content can be switched freely on the display screen like 2D content. The existing technology manufacturers' solutions are roughly as follows:

[0003] A. Solve the problem of horizontal and vertical screen switching by rotating or replacing the grating through mechanical control;

[0004] B. Rely on electronic grating to control the grating angle by changing the current to solve the problem of horizontal and vertical screen switching;

[0005] C. The above mechanical and electronic grating technologies are mixed to solve the problem;

[0006] However, when these solutions are used in electronic devices, the devices will become heavy, mechanically complex and costly.

[0007] The technical difficulty lies in the fact that when the naked-eye 3D display device switches between horizontal and vertical screens, the original 3D imaging relationship between the display content arrangement, the grating, the human eye and the display screen position is broken and needs to be reconstructed.

[0008] As for the current application of naked-eye 3D display technology in real life, the grating parameters of the completed display devices and the distance between the grating and the display screen are fixed and cannot be changed. Switching between horizontal and vertical screens will cause the grating to rotate, resulting in changes in the horizontal pitch of the grating relative to the displayed content. The effective viewing area will also change in position and size, but the position of the human eye relative to the screen has not changed. Ultimately, the eyes may not be in the effective viewing area, resulting in the picture seen naturally not being able to form a 3D stereoscopic image in the brain. [Summary of the invention]

[0009] The problems existing in the prior art solved by this application are:

[0010] At present, the application of naked-eye 3D display technology in real life is that the parameters of the grating itself and the distance between the grating and the display screen of the completed display devices are fixed and cannot be changed. Switching between horizontal and vertical screens will cause the grating to rotate, resulting in changes in the grating pitch relative to the displayed content. The effective viewing area will also change in position and size, but the position of the human eye relative to the screen has not changed. Ultimately, the eyes may not be in the effective viewing area, resulting in the picture seen naturally not being able to form a 3D stereoscopic image in the brain.

[0011] The solution to the technical problem of the present invention is:

[0012] A naked-eye 3D horizontal and vertical screen adaptive processing method is provided, comprising the following steps:

[0013] S1: A naked-eye 3D display device is preset for performing naked-eye 3D display;

[0014] S2: Determine the range of the grating inclination angle α of the inclined grating inside the above-mentioned naked-eye 3D display device; if the grating inclination angle α is 45 degrees or 135 degrees, jump to step S3; if the grating inclination angle α ranges from 0 degrees to 45 degrees or from 135 degrees to 180 degrees, jump to step S4; if the grating inclination angle α ranges from 45 degrees to 90 degrees or from 90 degrees to 135 degrees, jump to step S5;

[0015] S3: Under this grating inclination state, when the naked-eye 3D display device switches between horizontal and vertical screens, the grating pitch is equal and the effective viewing area does not change; further adjusting and changing the image arrangement angle of the display device to achieve horizontal and vertical screen adaptive viewing;

[0016] S4: Under this grating tilt state, when the naked-eye 3D display device switches between the horizontal screen and the vertical screen, the grating pitch changes from large to small. When the position of the human eye remains unchanged, the effective viewing area moves backward relative to the position of the human eye, and a binocular cross-viewing area phenomenon occurs; jump to step S6;

[0017] S5: In this grating tilt state, when the naked-eye 3D display device switches between the horizontal screen and the vertical screen, the grating pitch changes from small to large, and when the position of the human eye remains unchanged, the effective viewing area moves forward relative to the position of the human eye; jump to step S7;

[0018] S6: Further adjusting and increasing the length of the display device arrangement unit and adjusting the display device arrangement angle so that the effective viewing area moves forward to achieve horizontal and vertical screen adaptive viewing;

[0019] S7: Further adjusting and reducing the length of the display device arrangement unit and adjusting the display device arrangement angle so that the effective viewing area moves backward to achieve horizontal and vertical screen adaptive viewing;

[0020] S8: The above-mentioned naked-eye 3D horizontal and vertical screen adaptive processing is completed.

[0021] Preferably, in step S4, when the naked-eye 3D display device is in the horizontal screen state, the grating inclination angle α ranges from 0 degrees to 45 degrees or from 135 degrees to 180 degrees; when the naked-eye 3D display device is switched to the vertical screen state, the interval between the left and right views of the display device is further adjusted and expanded, and then the position and shape of the effective viewing area are adjusted synchronously, so that the left effective viewing area and the right effective viewing area are separated from each other.

[0022] Preferably, the display device terminal screen is an OLED or LCD screen.

[0023] Preferably, in step S4 to step S7, the specific steps of the image arrangement algorithm are: a. first calculate the grating pitch data when switching from one scene to another; b. given the grating pitch data and the relative position of the human eye to the screen, the image arrangement algorithm can control the length, width and front and back position of the effective viewing area by adjusting the unit length of the image arrangement or shifting the image arrangement up, down, left, and right according to the two data, so that the human eye always falls within the effective viewing area.

[0024] Preferably, before the image arrangement calculation and processing, the relative position data between the initial scene screen and the grating and the spatial position data of the human eye relative to the screen are known; when the display device switches between landscape and portrait, the grating rotates 90 degrees, and the horizontal pitch of the grating relative to the screen changes in length, resulting in a change in the effective viewing area compared to the initial scene. When the spatial position data of the human eye relative to the screen remains unchanged, the correspondence between the effective viewing areas of the screen, the grating, and the human eye is broken; the correspondence between the effective viewing areas of the screen, the grating, and the human eye is further reconstructed through the image arrangement algorithm to ensure that the human eye is always within the effective viewing area.

[0025] The technical effects of solving the technical problem in this application are as follows:

[0030] In order to make the purpose, technical solution and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0031] See also Figures 1 to 3 In the first embodiment of the present invention, a naked-eye 3D horizontal and vertical screen adaptive processing method 1 includes the following steps:

[0032] S1: A naked-eye 3D display device is preset for performing naked-eye 3D display;

[0033] S2: Determine the range of the grating inclination angle α of the inclined grating inside the above-mentioned naked-eye 3D display device; if the grating inclination angle α is 45 degrees or 135 degrees, jump to step S3; if the grating inclination angle α ranges from 0 degrees to 45 degrees or from 135 degrees to 180 degrees, jump to step S4; if the grating inclination angle α ranges from 45 degrees to 90 degrees or from 90 degrees to 135 degrees, jump to step S5;

[0034] S3: Under this grating inclination state, when the naked-eye 3D display device switches between horizontal and vertical screens, the grating pitch is equal and the effective viewing area does not change; further adjusting and changing the display device's image arrangement angle to achieve horizontal and vertical screen adaptive viewing; see the attached figure of the specification Figure 2 The leftmost view in the figure;

[0035] S4: Under this grating tilt state, when the naked-eye 3D display device switches between horizontal and vertical screens, the grating pitch changes from large to small. When the position of the human eye remains unchanged, the effective viewing area moves backward relative to the position of the human eye, and a binocular cross-viewing phenomenon occurs; jump to step S6; see the attached figure of the specification Figure 2 middle view;

[0036] S5: Under this grating tilt state, when the naked-eye 3D display device switches between horizontal and vertical screens, the grating pitch changes from small to large, and when the position of the human eye remains unchanged, the effective viewing area moves forward relative to the position of the human eye; jump to step S7; see the attached figure of the specification Figure 2 The rightmost view in the figure;

[0037] S6: Further adjusting and increasing the length of the display device arrangement unit and adjusting the display device arrangement angle so that the effective viewing area moves forward to achieve horizontal and vertical screen adaptive viewing;

[0038] S7: Further adjusting and reducing the length of the display device arrangement unit and adjusting the display device arrangement angle so that the effective viewing area moves backward to achieve horizontal and vertical screen adaptive viewing;

[0039] S8: The above-mentioned naked-eye 3D horizontal and vertical screen adaptive processing is completed.

[0040] According to the principle, the length, width and front-to-back position relationship of the effective viewing area are directly related to the unit length of the layout, and the left-right position of the effective viewing area can be achieved by moving the layout (moving the layout up, down, left, and right); when the display device switches from one scene to another, such as switching from horizontal to vertical or vice versa, the grating pitch will change with the change of the grating inclination angle. It can be roughly divided into three cases: step S3, step S4 and step S5.

[0041] The present application adopts the following steps: S1: presetting a naked-eye 3D display device for naked-eye 3D display; S2: determining the range of the grating inclination angle α of the inclined grating inside the naked-eye 3D display device; if the grating inclination angle α is 45 degrees or 135 degrees, jumping to step S3; if the grating inclination angle α ranges from 0 degrees to 45 degrees or from 135 degrees to 180 degrees, jumping to step S4; if the grating inclination angle α ranges from 45 degrees to 90 degrees or from 90 degrees to 135 degrees, then Jump to step S5; S3: Under this grating tilt state, when the naked eye 3D display device switches between horizontal and vertical screens, its grating pitch is equal, and the effective viewing area does not change; further adjust and change the display device's image arrangement angle to achieve horizontal and vertical screen adaptive viewing; S4: Under this grating tilt state, when the naked eye 3D display device switches between horizontal and vertical screens, its grating pitch changes from large to small, and when the position of the human eye remains unchanged, the effective viewing area moves backward relative to the position of the human eye, resulting in binocular cross-viewing area Phenomenon; jump to step S6; S5: under this grating inclination state, when the above-mentioned naked-eye 3D display device switches between horizontal and vertical screens, its grating pitch changes from small to large, and when the position of the human eye remains unchanged, the effective viewing area moves forward relative to the position of the human eye; jump to step S7; S6: further adjust and increase the length of the display device arrangement unit and combine with adjusting the display device arrangement angle to move the effective viewing area forward to achieve adaptive viewing of horizontal and vertical screens; S7: further adjust and reduce the length of the display device arrangement unit and combine with adjusting the display device arrangement angle to move the effective viewing area backward to achieve adaptive viewing of horizontal and vertical screens; S8: The above-mentioned naked-eye 3D horizontal and vertical screen adaptive processing is completed. In actual application, through optical design (tilted grating) and 3D content arrangement algorithm and distribution, without adding any mechanical, electronic and other equipment and hardware, the horizontal and vertical screen scenes of the naked-eye 3D device are automatically adapted to ensure that the user is in the effective viewing area in both scenarios, which can effectively reduce the thickness and weight of electronic equipment and has a high cost advantage.

[0042] Almost all naked-eye 3D display devices on the market currently have known and fixed grating parameters and grating distance from the screen after they are manufactured into finished products. In the inclined grating scheme of the present application, switching between horizontal and vertical screens will cause the grating to rotate, resulting in a change in the grating pitch relative to the displayed content, thereby causing the effective viewing area to shift forward and backward (i.e., the optimal viewing distance shifts forward and backward). When the position of the human eye and the distance of the grating from the screen do not change, the position of the effective viewing area can only be corrected by adjusting the image arrangement algorithm.

[0043] It can be seen from the above first embodiment that when the grating inclination angle α=45° or α=135°, it is the best angle for naked-eye 3D horizontal and vertical screen adaptation.

[0044] However, although the content of 2D vertical screen short videos is becoming increasingly rich, the proportion of 3D vertical screen short videos in 3D content is still very small. Therefore, in the application of naked-eye 3D technical solutions, the horizontal screen state is still the main one, and the vertical screen state is supplementary.

[0045] At present, the naked-eye 3D technology system is not fully popularized in life. In actual technical applications, the compatibility of 2D images still needs to be considered. In theory, the grating pitch should be as large as possible in the horizontal screen state, that is, the grating inclination angle range is 0℃<α<45℃ or 135℃<α<180℃ and the closer to 0℃ or 180℃, the lower the crosstalk of the 3D image. However, in the horizontal screen state, the larger the grating pitch, the smaller the grating pitch in the vertical screen. Too small a grating pitch will result in that even after adjusting the image arrangement angle and increasing the unit length of the image arrangement to the maximum value, the human eye is still in front of the effective visual area, and the phenomenon of crossing the visual area occurs. That is, in certain circumstances, the 3D imaging stability rate of the first embodiment is not 100%;

[0046] Based on this, on the basis of the first embodiment, the present application optimizes the different arrangement algorithms and distributions of 3D content in horizontal and vertical screens, so that when the 3D content is switched between horizontal and vertical screens, the human eye is within the effective viewing area; see the technical solution of the second embodiment for details;

[0047] By observing commonly used horizontal and vertical screen devices in real life, such as mobile phones and tablets, people usually use the vertical screen mode more frequently in 2D state; 3D content is almost always in a 4:3 or 16:9 ratio, so 3D scenes should be viewed in horizontal mode.

[0048] It should be noted that the display device terminal screen is an OLED or LCD screen. Figure 1 and attached Figure 2 shown.

[0049] See also Figure 4In the second embodiment of the present invention, when the naked-eye 3D display device is in the horizontal screen state, the grating inclination angle α ranges from 0 degrees to 45 degrees or from 135 degrees to 180 degrees; when the naked-eye 3D display device is switched to the vertical screen state, the interval between the left and right views of the display device is further adjusted and expanded, and then the position and shape of the effective viewing area are adjusted synchronously, so that the left effective viewing area and the right effective viewing area are separated from each other.

[0050] The second embodiment adopts the common 1 and 2 rows of pictures in the horizontal screen state (see the attached manual). Figure 2 The left and middle views in the figure) and ensure that the grating inclination angle is within the range of 0℃<α<45℃ or 135℃<α<180℃ (the grating pitch is longer in horizontal mode). This can ensure the highest resolution of 3D imaging and reduce the crosstalk area. Switch to the vertical mode and use the Figure 3 The right view layout in the image arrangement adjusts the position and shape of the effective viewing area by expanding the interval between the left and right views, solving the 3D imaging problem caused by the cross-viewing area of ​​both eyes. At the same time, in the vertical screen state, the grating pitch is shorter, which interferes less with the picture in its 2D state.

[0051] The steps to implement the method in a specific application are as follows:

[0052] S1: The relative position data between the initial scene screen and the grating and the spatial position data of the human eye relative to the screen are known;

[0053] S2: When the display device switches between horizontal and vertical screens, the grating rotates 90 degrees, and the grating pitch of the grating relative to the screen changes, resulting in a change in the effective viewing area compared to the initial scene. When the spatial position data of the human eye relative to the screen remains unchanged, the corresponding relationship between the effective viewing area of ​​the screen, the grating, and the human eye is broken, and it cannot be guaranteed that the human eye is still in the effective viewing area when the scene is switched;

[0054] S3: To reconstruct the correspondence between the screen, grating, and the effective visual area of ​​the human eye, and ensure that the human eye is always in the effective visual area, the specific processing method of the image arrangement algorithm is as follows: a. First, calculate the grating pitch data when switching from one scene to another (refer to the attached figure of the manual Figure 1 The horizontal and vertical screen switching diagram, the grating spacing is known to be L3, and the grating pitch can be calculated by the inclination angle between the grating and the screen); b. Known grating pitch data and the relative position of the human eye to the screen, the image arrangement algorithm can control the length, width and front and back position of the effective viewing area by adjusting the unit length of the image arrangement or shifting the image up, down, left, and right based on these two data, so that the human eye always falls within the effective viewing area.

[0055] Compared with the prior art, the naked-eye 3D horizontal and vertical screen adaptive processing method 1 of the present invention adopts the following steps: S1: presetting a naked-eye 3D display device for naked-eye 3D display; S2: determining the size range of the grating inclination angle α of the inclined grating inside the above-mentioned naked-eye 3D display device; if the grating inclination angle α is 45 degrees or 135 degrees, jumping to step S3; if the size range of the grating inclination angle α is between 0 degrees and 45 degrees or between 135 degrees and 180 degrees, jumping to step S4; if the size range of the grating inclination angle α is between 4 If the grating angle is between 5 and 90 degrees or between 90 and 135 degrees, the process jumps to step S5; S3: in this grating inclination state, when the naked-eye 3D display device switches between the horizontal screen and the vertical screen, the grating pitch is equal, and the effective viewing area does not change; further adjust and change the display device's image arrangement angle to achieve horizontal and vertical screen adaptive viewing; S4: in this grating inclination state, when the naked-eye 3D display device switches between the horizontal screen and the vertical screen, the grating pitch changes from large to small, and when the position of the human eye remains unchanged, the position of the effective viewing area relative to the human eye is changed. The position moves backward, resulting in binocular cross-viewing phenomenon; jump to step S6; S5: under this grating inclination state, when the above-mentioned naked-eye 3D display device switches between horizontal and vertical screens, its grating pitch changes from small to large, and when the position of the human eye remains unchanged, the effective viewing area moves forward relative to the position of the human eye; jump to step S7; S6: further adjust and increase the length of the display device arrangement unit and adjust the display device arrangement angle to move the effective viewing area forward to achieve horizontal and vertical screen adaptive viewing; S7: further adjust and reduce the length of the display device arrangement unit and adjust the display device arrangement angle to move the effective viewing area backward to achieve horizontal and vertical screen adaptive viewing; S8: the above-mentioned naked-eye 3D horizontal and vertical screen adaptive processing is completed. In actual application, through optical design (tilted grating) and 3D content arrangement algorithm and distribution, without adding any mechanical, electronic and other equipment and hardware, the naked-eye 3D device horizontal and vertical screen scenes are automatically adapted to ensure that the user is in the effective viewing area in both scenarios, which can effectively reduce the thickness and weight of electronic equipment and has a high cost advantage.
