Description

A method for changing the convergent position of menus on 3D TV

technical field

The invention belongs to the OSD menu display technology of TV, in particular to the OSD menu display technology of 3D TV.

Background technique

As TV functions become more and more complex and diverse, more and more menu options need to be controlled by users on the TV system. However, the menu display on the current TV equipment is directly superimposed on the video content to be displayed. The position of the menu to the human eye is fixed. The existing menu display technology on the 3D TV can realize the normal display of the OSD menu on the 3D TV just like the 2D TV. Even if the menu converges between the screen and the human eyes, it cannot converge behind the screen, let alone dynamically change the specific position where the menu converges, so that the OSD menu display can have a depth of field effect.

Contents of the invention

The purpose of the present invention is to provide an OSD menu display technology on a 3D TV, aiming at solving the problem in the prior art that the OSD menu display does not have the effect of depth of field.

The present invention is achieved in this way, a method for changing the convergence position of menus on a 3D TV, including superimposing the menu display content of a set size on the input 3D video signal, the 3D video signal includes a left-eye image and a right-eye image, It also includes: calculating the initial position where the menu display content is superimposed on the left-eye image, calculating the initial position where the menu display content is superimposed on the right-eye image, so that the menu can converge on the screen position of the 3D TV; displaying the menu The position of the content on the left-eye image is moved to the left/right by a first set distance relative to its initial position, and at the same time, the position of the menu display content on the right-eye image is moved in the opposite direction relative to its initial position by the first set distance The same distance so that the menus can converge to a second set distance behind/in front of the screen position. In this way, the present invention not only enables the user to see the menus converging on the screen position, but also allows the user to see the menus converging in front of the screen or behind the screen, so that the OSD menu display can have a depth of field effect.

Wherein, the 3D video signal is a left-right format, a top-bottom format, a horizontal interleaved format, a vertical interleaved format or a left-right sequence format. In this way, the present invention can be applied to 3D video signals of various formats.

If the 3D video signal is a left-right format, the menu display content can be reduced to half of the set size in the horizontal direction and superimposed on the left-eye image and right-eye image on the input 3D video signal, and then the menu display The content is doubled in the horizontal direction by the video algorithm and then placed on the screen; it can also be directly superimposed on the 3D video signal with a menu display of normal size. In this way, it is convenient to be compatible with the OSD menu display technology in the 3D TV in which the existing 3D video signal is in the left-right format.

If the 3D video signal is in the top-bottom format, the menu display content can be reduced to half of the set size in the vertical direction and superimposed on the input 3D video signal on the left-eye image and right-eye image, and then the menu display The content is doubled in the vertical direction by the video algorithm and then placed on the screen; it can also be directly superimposed on the 3D video signal with a menu display of normal size. In this way, it is convenient to be compatible with the OSD menu display technology in the 3D TV in which the existing 3D video signal is in the top-bottom format.

In the embodiment of the present invention, the direction of the menu moving to the left/right and the value of the first set distance are realized by changing the value of the horizontal position register of the menu display.

In the embodiment of the present invention, shortcut keys or menu function items can also be set to change the value of the horizontal position register displayed by the menu so as to manually and continuously adjust the convergence position of the menu.

The adjustment range of the shortcut key or menu function item is set from -N to +N, and the value of N can be 10, wherein, when the adjustment range is set to zero, the value corresponding to the first set distance is zero, and the minus sign A positive sign indicates that the menu on the left-eye image moves to the left, and a positive sign indicates that the menu on the left-eye image moves to the right.

In this way, the user can manually and continuously adjust the menu convergence position through shortcut keys or menu function items.

In the embodiment of the present invention, it is also possible to: capture the viewing distance of the user, determine the appropriate viewing distance, calculate the direction and value of the second set distance, and then calculate the direction and value of the first set distance , by automatically changing the value of the horizontal position register of the menu display to automatically adjust the menu convergence position. The capture of the user's viewing distance is achieved by detecting infrared waves or ultrasonic waves.

In this way, the convergence position of the menu is automatically adjusted as the viewing distance of the user changes.

Compared with the prior art, the beneficial effects brought by the method for changing the menu convergence position on the 3D TV of the present invention include: on the 3D TV, through the matching 3D glasses system, there is no need to change the original chip menu processing module, and Without changing the design structure of the system, without increasing any hardware costs, only need to change the implementation method of the menu software, so that the user can see the menus that converge at different positions from the screen, thereby improving the comfort of the user experience.

Detailed ways

In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.

The 3D video content of the 3D TV of the present invention can be a left-right format, a top-bottom format, a horizontal interleaved format, a vertical interleaved format, etc. The principle and implementation process of the present invention will be described in detail below by taking a frame of left and right format video signals as an example.

First of all, in the menu design part, it can be designed to display a menu with half the size of the 2D screen menu in the horizontal direction on the left half of the screen, and also display a menu with half the size of the 2D screen menu in the horizontal direction on the right half of the screen. Everything in is exactly the same.

Secondly, through the back-end 3D video processing technology, one frame of left-eye format video is processed into two frames of video, one frame is the left-eye image L, and the other is the right-eye image R. In this way, the content of the menu superimposed on the L image is stretched horizontally to double the original menu, and the content superimposed on the R image will also be stretched horizontally to double the original menu.

Thirdly, through the 3D glasses system, the left eye can only see the left eye image, and the right eye can only see the right eye image, so that the menu that the user sees through the left and right lenses of the 3D glasses is processed by the brain and feels that the menu is completely presented to the user. At present, since the relative positions of the menus superimposed on the left and right images are the same, the menus seen by the user are converged on the TV screen.

In this case, the user can adjust related function adjustment items through the menu or shortcut keys, for example, the adjustment range of the convergence position of the menu is set to -10 to 10.

a) When the menu convergence position is set to 0, the software program sets the horizontal position register value displayed by the chip’s OSD to h, the vertical position register value to v, and the menu position (XL1, YL1) and right The menu positions (XR1, YR1) on the field image are all the same: XL1=XR1=k1(h), YL1=YR1=k2(v). In this way, the menus on the left and right eye images that the user sees through the glasses will be gathered on the screen without the effect of depth of field.

b) When the menu convergent position is adjusted to -a to the left, the software program, for the menu superimposed on the left-eye image, sets the value of the horizontal position register displayed by the OSD of the chip to h+ax, and the value of the vertical position register is still v; For the menu superimposed on the right-eye image, the value of its horizontal position register is h-ax, and the value of its vertical position register is still v. The menu position (XL2, YL2) superimposed on the left-eye image like this is: XL2=k1(h+ax), YL2=k2(v); The menu position (XR2, YR2) superimposed on the right-eye image is: XR2 =k1(h-ax), YR2=k2(v). That is, when the menu convergence position adjustment item is -a, the menu position on the left-eye image moves horizontally to the right by k1(ax) relative to the menu convergence position adjustment item, and the menu position on the right-eye image converges relative to the menu When the position is 0, it is moved horizontally by k1(ax) to the left. In this way, the menus on the left and right eye images that the user sees through the glasses will be gathered in front of the screen, and the menus have the effect of highlighting the depth of field displayed on the TV screen.

c) When the menu convergence position is adjusted to b to the left, the software program will set the horizontal position register value displayed by the OSD of the chip to h-bx for the menu superimposed on the left eye image, and the vertical position register value is still v ; For the menu superimposed on the right-eye image, set the value of its horizontal position register to h+bx, and the value of its vertical position register to v. The menu position (XL3, YL3) superimposed on the left-eye image is: XL3=k1(h-bx), YL3=k2(v); the menu position (XR3, YR3) superimposed on the right-eye image is: XR3 =k1(h+bx), YR3=k2(v). That is, when the menu convergence position adjustment item is b, the menu position on the left-eye image relative to the menu convergence position adjustment item is 0 and moves horizontally to the left by k1 (bx), and the menu position on the right-eye image is relative to the menu convergence position When it is 0, it moves k1(bx) horizontally to the right. In this way, the menus on the left and right eye images that the user sees through the glasses will be gathered behind the screen, and the menu has a depth-of-field effect that is displayed on the back of the TV screen.

It can be seen that through the above technical measures, the user can see the menus converging in front of the screen, on the screen, and behind the screen, and can manually adjust the converging position of the menus.

In addition, the distance between the TV and the user can be calculated through distance detection technology, such as infrared and ultrasonic detection technology. The software of the 3D TV can automatically adjust the depth of field of the menu through the distance, so that when the user is closer to the TV, the menu converges at a farther position behind the screen; when the user is farther away from the TV, the menu converges in front of the screen.

Similarly, for 3D input images in the top-bottom format, interleaved format, and sequential format of one frame left and one frame right, the menu is also designed into a corresponding structure in the pre-processing stage, and other menus are converged and manually and automatically adjusted. The method for menu convergence is the same.

It includes: a video processing module, a menu processing module, a video 3D processing module, a video display driver module and 3D glasses. The video processing module is used to zoom, read, and reorganize the left and right eye signals in the input 3D format video with special algorithms so that the video 3D processing module can receive and process them, and enter the matching 3D glasses system to make the left eye only The left eye image can be seen, and the right eye can only see the right eye image.

Figure 2b corresponds to the menu processing module, which superimposes the OSD menu on the left and right screens, displays menu A with half the size of the 2D screen menu in the horizontal direction on the left half screen part L, and displays the 2D screen menu on the right half screen part R. Menu A is half the size in the horizontal direction, and all the contents in the two menus are exactly the same, and these two menus are superimposed on the image contents L and R at the same time. Figure 2c corresponds to the video 3D processing module, which doubles the left and right OSD menus and signals horizontally. In this way, each frame of left and right format video is processed into two frames of video, one frame is the image L for the left eye, and the other frame is the image for the right eye In image R, the menu content superimposed on the video is stretched horizontally to double the original size of menu A, so that the menu size and content of the left and right eye images are exactly the same.
