Invention embodiment

Example

[0039] Referring to FIGS. 1 and 2, the naked-eye 3D dynamically adjusting display screen layout method of this embodiment is applied to an electronic device with a display screen, and the display screen is covered with a 3D film; alternatively, the 3D film is a lenticular lens The 3D film, or the 3D film is a visually impaired 3D film. It can be understood that the 3D film and the display screen can be an integrated structure, that is, the 3D film is covered on the display screen during the production process as a component of the display screen; of course, the 3D film and the display screen can also be a split structure. That is, the display screen and the 3D film are independent of each other, and the 3D film can be pasted on the display screen when needed. This setting is convenient for the display screen without the naked eye 3D display function. The naked eye 3D viewing function can be realized by pasting the 3D film. The operation is simple and the cost is low. Specifically, the method includes the following steps:

[0040] S1. Obtain the screen distance between the human eye and the 3D film.

[0041] Specifically, during the viewing process, the distance between the user's eyes and the screen is constantly changing. Because the time distance between the 3D film and the display screen is fixed, to ensure that the user's left eye can only see the left in the 3D video source. In the eye view, the right eye only sees the right eye image in the 3D video source, and the display layout of the display screen needs to be continuously adjusted according to the distance of the user from the screen. To adjust the display layout of the display screen, it is necessary to know the distance between the user's eyes and the display screen, because the images seen by the user through the 3D film are different at different distances from the screen.

[0042] Alternatively, in this embodiment, the user's eye image can be acquired through a camera, and the distance between the human eye and the 3D film from the screen can be obtained according to the eye image. Further, obtaining the distance from the screen between the human eye and the 3D film according to the eye image includes:

[0043] The interpupillary distance of the user's pupil in the eye image is acquired, and the identification of the interpupillary distance in the eye image can be realized by image recognition technology.

[0044] The distance from the screen is obtained from the interpupillary distance and the ratio of the read distance from the screen, where the ratio of the distance from the screen is the ratio of the preset distance from the screen to the standard distance from the screen. Referring to FIG. 3, this embodiment provides a process for obtaining the distance ratio from the screen

[0045] S11. Set the pixel intercept of the display screen to a preset standard pixel intercept, the preset standard pixel intercept is the one-time display width of a monocular image, and the display screen uses the preset standard pixel intercept to display the layout. Understandable After fixing the preset standard pixel intercept, since the distance between the 3D film and the display screen is fixed, the user's best viewing distance is also fixed.

[0046] S12. When the user achieves the best viewing effect by adjusting his viewing distance, a confirmation instruction is generated through touch operation, key operation, voice operation, etc. After the electronic device detects the confirmation instruction, it indicates that the user is already at the best viewing distance. When the user is at the best viewing distance, the user's eye image is obtained through the camera, and the interpupillary distance of the user's pupil in the eye image is obtained. Since the parameters of the camera are known and the image parameters obtained by the camera are known, the interpupillary distance can be obtained by identifying the position of the pupil in the image, for example, the interpupillary distance can be obtained by pixels.

[0047] S13. Calculate the standard distance between the human eye and the 3D film from the screen according to the interpupillary distance.

[0048] S14. Calculate the ratio of the preset distance from the screen to the standard distance from the screen to obtain the ratio of the distance from the screen, and save the ratio of the distance from the screen.

[0049] Alternatively, in this embodiment, the distance between the human eye and the 3D film from the screen can also be obtained through a distance sensor. The distance sensor may be a distance sensor that comes with the electronic device; a separate distance sensor may also be used. The sensor obtains the distance from the screen and transmits it to the electronic device. Preferably, the distance sensor includes, but is not limited to, a laser distance sensor, an ultrasonic distance sensor, an infrared distance sensor, and the like.

[0050] S2. Adjust the display layout of the display screen according to the distance from the screen. By adjusting the display layout of the display screen, the user's left eye can only see the left eye view in the 3D video source, and the right eye can only see the right eye image in the 3D video source, thereby generating a clear 3D image.

[0051] This embodiment automatically dynamically adjusts the display layout of the display screen by monitoring the distance between the user's eyes and the display screen.

, So that users can see clear 3D images at different viewing distances, and improve user viewing experience. Example

[0052] Referring to FIG. 1, L represents the distance between the human eye and the 3D film (distance from the screen), d represents the distance between the 3D film and the display screen (overhead height), and P represents the 3D film row span value (physical cut Distance), Wp represents the single-eye image display width (pixel intercept), and Q represents the interpupillary distance. On the basis of the foregoing embodiment, the method for dynamically adjusting the layout of the display screen according to the distance from the screen in the naked eye 3D dynamic adjustment method of the display layout of this embodiment includes

[0053] The pixel intercept in the display screen is adjusted according to the distance from the screen, and the pixel intercept is the one-time display width of the monocular image.

Further, adjusting the pixel intercept in the display screen according to the distance from the screen includes: [0054] Calculate the pixel intercept W _p in the display screen according to the following formula _:

[0055] L=d*(Q+W _P )AV _P

[0056] Where L is the distance from the screen, d is the distance from the 3D film to the display screen, and Q is the interpupillary distance.

[0057] In this embodiment, by monitoring the distance between the user's eyes and the display screen, the display layout of the display screen is automatically adjusted dynamically, so that the user can see clear 3D images at different viewing distances, and the user viewing experience is improved. Example

[0058] On the basis of the foregoing embodiment, in the naked eye 3D dynamic adjustment method of the display screen layout of this embodiment, the off-screen distance ratio is:

[0059] Q ₀ *(W/q ₀ )/L ₀

[0060] where Q. Is the preset standard interpupillary distance, W is the width of the camera picture, q. Is the interpupillary distance of the user's pupil in the eye image, and L _Q is the preset standard distance from the screen.

[0061] Further, in the naked eye 3D dynamic adjustment method of the display screen layout of this embodiment, the standard distance L from the screen is preset.

The calculation formula is:

[0062] L o=d*(Q o + W _p o) AV _p0

[0063]

Is the preset standard interpupillary distance, and W _pQ is the preset standard pixel intercept.

[0064] In this embodiment, by monitoring the distance between the user's eyes and the display screen, the display layout of the display screen is automatically adjusted dynamically, so that the user can see clear 3D images at different viewing distances, and the user viewing experience is improved.
