In addition, the embodiments and features of the embodiments of the present application may be combined with each other without conflict.
Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the invention is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.
As shown in fig. 1, an embodiment of the present invention provides a 3D display system, which includes a display control system 10 and a display screen 20, where the display screen 20 is a polarization type 3D display screen, and can output a picture with 2 orthogonal polarization directions, for example, one polarization direction is horizontal and the other polarization direction is vertical. The viewer wears the polarization glasses 30, and 2 lenses of the polarization glasses 30 are respectively provided with polarization planes with different polarization directions. The polarization directions of the 2 lenses of the polarized glasses 30 correspond to the 2 polarization directions of the output screen of the display panel 20. Thus, the right eye can obtain the right eye image, the left eye can obtain the left eye image, and the two images together form the stereo image. The 3D display control method is specifically explained below.
As shown in fig. 2, an embodiment of the present invention provides a 3D display control method, including:
s100, receiving at least one frame of 3D image signal, wherein the one frame of 3D image signal comprises a left-eye image frame and a right-eye image frame;
s300, synthesizing to obtain a preset number of synthesized image frames according to the left eye image frame and the right eye image frame, wherein each synthesized image frame at least comprises partial content of the left eye image frame and partial content of the right eye image frame;
and S500, outputting the synthesized image frame for display according to a preset frame rate.
At least one frame of 3D image signal is received from an externally input 3D video source data. Each of the frame 3D image signals includes a left-eye image frame and a right-eye image frame. The left-eye image frame includes only image data to be output to the left eye, and the right-eye image frame includes only image data to be output to the right eye. After the left eye image data and the right eye image data are respectively acquired by the left eye and the right eye of the audience, the three-dimensional image can be synthesized, and 3D display is achieved. It should be noted that the left-eye image frame and the right-eye image frame mentioned herein are both 3D image signals belonging to one frame.
After the left eye image frame and the right eye image frame are obtained, the content of the left eye image frame and the content of the right eye image frame can be combined and synthesized to obtain a preset number of synthesized image frames. The composite image frame includes at least a portion of the content of the left eye image frame and a portion of the content of the right eye image frame. The content set of all composite image frames includes all content in the left-eye image frame and the right-eye image frame. And determining the preset number of the synthesized image frames according to the proportion of the partial content of the left-eye image frames to the complete left-eye image frames and the proportion of the partial content of the right-eye image frames to the complete right-eye image frames in the synthesized image frames. A preset number of at least 2 frames.
And after a preset number of composite image frames are obtained, outputting the composite image frames according to a preset frame rate, and displaying on the polarized light type 3D display screen. The viewer can watch the glasses by wearing the polarized glasses, and a 3D display effect is obtained.
The preset frame rate may be determined according to the original frame rate and the preset number of the synthesized images, for example, the preset frame rate may be a product of the original frame rate and the preset number, or may be a half of the product of the original frame rate and the preset number, or may be a multiple of the product of the original frame rate and the preset number (the multiple is greater than 1). In one implementation, the preset frame rate is preferably a product of the original frame rate and a preset number. For example, the original frame rate is 60Hz, the preset number is 2 frames, and the preset frame rate is 120 Hz. Therefore, the complete display of all the synthesized images can be ensured, and the omission of the picture content is avoided.
In practical application, a proper preset frame rate determining mode can be selected according to different control modes of the original frame rate for displaying the left eye image frame and the right eye image frame. It is understood that other necessary factors may be combined to adjust for good 3D display effect.
The content of the left-eye image frame and the content of the right-eye image frame are combined, the obtained composite image frame simultaneously contains partial content of the left-eye image frame and partial content of the right-eye image frame, and the content set of all the composite image frames contains all the content in the left-eye image frame and the right-eye image frame, and then the composite image frame is output to a polarization type 3D display screen for display. Compared with the existing shutter type 3D display technology, the method does not need heavy shutter type 3D glasses, and is lower in cost; and the content set of all the composite image frames contains all the contents in the left-eye image frame and the right-eye image frame, no image data is lost, and the image restoration effect is good. Compared with the existing polarization type 3D display technology, the method has the advantages that the synthesized image frame displayed by each image simultaneously contains partial content of the left-eye image frame and partial content of the right-eye image frame, the image brightness is higher, and the user viewing experience is better.
Specifically, in step S300, a preset number of synthesized image frames are synthesized according to the left-eye image frame and the right-eye image frame, and various implementation manners are possible. Which in the following exemplifies several ways.
As shown in fig. 3, the first combining method of the combined image frame is to split the left-eye image frame into a first part and a second part, split the right-eye image frame into a third part and a fourth part, combine the first part of the left-eye image frame and the third part of the right-eye image frame into a combined image frame one, and combine the second part of the left-eye image frame and the fourth part of the right-eye image frame into a combined image frame two. The splitting processing mode may be an interval extraction mode, the first part and the second part have the same size, and the third part and the fourth part have the same size. Thus, 2 composite image frames are obtained, and the content set of the 2 composite image frames includes all the contents of the left-eye image frame and the right-eye image frame. For example, as shown in fig. 3, the left-eye image frame includes L1L2L3L4L5L6 …, and the right-eye image frame includes R1R2R3R4R5R6 …. In the synthesis, the left-eye image frame is equally divided into a first part of L1L3L5 … and a second part of L2L4L6 …, and the right-eye image frame is equally divided into a third part of R1R3R5 … and a fourth part of R2R4R6 … in an interval extraction mode. Then, the first portion of the left eye image frame of L1L3L5 … and the third portion of the right eye image frame of R1R3R5 … are combined into a composite image frame, R1L1R3L3R5L5 …, and the second portion of the left eye image frame of L2L4L6 … and the fourth portion of the right eye image frame of R2R4R6 … are combined into a composite image frame, second R2L2R4L4R6L6 ….
As shown in fig. 4, the second synthesis method for synthesizing the image frames is to split one of the left-eye image frame and the right-eye image frame into two parts, and then combine the two parts with the left-eye image frame or the right-eye image frame that is not split, so as to obtain a synthesized image frame. Specifically, the left-eye image frame may be split into a first part and a second part according to a splitting manner of interval extraction, and then the first part of the left-eye image frame is combined with the right-eye image frame to obtain a first composite image frame; the second part of the left eye image frame is combined with the right eye image frame to obtain a composite image frame two. Correspondingly, the right-eye image frame may also be split into a third portion and a fourth portion in an interval extraction manner, and the third portion and the fourth portion of the right-eye image frame are respectively combined with the left-eye image frame to obtain a first composite image frame and a second composite image frame. The first part and the second part are equal in size, and the third part and the fourth part are equal in size. For example, as shown in fig. 4, the left-eye image frame is equally divided into a first portion of L1L3L5 … and a second portion of L2L4L6 …, and then combined with the right-eye image frame to obtain a first composite image frame of R1L1R2L3R3L5R4L7R5 … and a second composite image frame of R1L2R2L4R3L6R4L8R5 …. Compared with the first synthesis mode, the synthesis image frames obtained in the synthesis mode have the advantages that the content of each synthesis image frame is more than that of a single left-eye image frame or right-eye image frame, and the brightness of the image can be effectively improved.
As shown in fig. 5, the third synthesis method for synthesizing the image frames is to split the left-eye image frame and the right-eye image frame into N parts (N is greater than or equal to 2, N is an integer), wherein the N parts belonging to the left-eye image frame are respectively combined with the right-eye image frame to obtain N synthesized image frames, and the N parts belonging to the right-eye image frame are respectively combined with the left-eye image frame to obtain the other N synthesized image frames. For example, as shown in fig. 2, taking N as an example, the left-eye image frame and the right-eye image frame are respectively split into 2 parts by way of interval extraction, i.e., the left-eye image frame is equally divided into a first part of L1L3L5 … and a second part of L2L4L6 …, and the right-eye image frame is equally divided into a third part of R1R3R5 … and a fourth part of R2R4R6 …. Then, combining the first part L1L3L5 … and the second part L2L4L6 … of the left-eye image frame with the right-eye image frame respectively to obtain a first composite image frame of R1L1R2L3R3L5R4L7R5 … and a second composite image frame of R1L2R2L4R3L6R4L8R5 …; the third portion R1R3R5 … and the fourth portion R2R4R6 … of the right eye image frame are combined with the left eye image frame to produce a composite image frame three of L1R1L2R3L3R5L4R7L5 … and a composite image frame four of L1R2L2R4L3R6L4R8L5 …. Therefore, the content of each composite image frame is more than that of a single left-eye image frame or right-eye image frame, and the brightness of the image can be effectively improved; and more display picture frames are obtained, and the display effect is better.
In the foregoing several ways, for each frame of the 3D image signal, the output synthesized image frame is synthesized based on the left-eye image frame and the right-eye image frame in the frame of the 3D image signal. In consideration of the dynamics of the display screen, in the fourth combination method, as shown in fig. 6, when the combined image frame is obtained, the left-eye image frame and the right-eye image frame in the 3D image signal of the next frame are additionally used. For example, after a plurality of frame composite image frames are obtained by using the left-eye image frame and the right-eye image frame in the 3D image signal of the frame according to the above-mentioned several composite modes, one of the left-eye image frame and the right-eye image frame in the 3D image signal of the frame and one of the left-eye image frame and the right-eye image frame in the 3D image signal of the next frame are further added to obtain a plurality of additional frame composite images according to the above-mentioned composite modes. For example, as shown in fig. 6, the left eye image frame and the right eye image frame in the n-th frame 3D image signal are processed, and the left eye image frame and the right eye image frame in the n + 1-th frame 3D image signal are additionally considered. The left-eye image frame and the right-eye image frame in the nth frame of 3D image signal are first split into two parts according to the second synthesis method, and then are combined with the right-eye image frame, respectively, to obtain a first synthesized image frame R1L1R2L3R3L5R4L7R5 … and a second synthesized image frame R1L2R2L4R3L6R4L8R5 …. Then, the left-eye image frame and the n +1 th-frame right-eye image frame in the n-th-frame 3D image signal are split into two parts according to the second synthesis manner, and then the two parts are combined with the left-eye image frame in the n-th-frame 3D image signal, so as to obtain a synthesized image frame three L1R1 'L2R 3' L3R5 'L4R 7' L5 …, and a synthesized image frame four L1R2 'L2R 4' L3R6 'L4R 8' L5 …. Therefore, the brightness of the picture is effectively improved, the picture is more coherent, and the display effect is better.
It can be understood that, in the fourth synthesis mode, any one of the 3 synthesis modes described above may be adopted for the splitting and combining of the left-eye image frame and the right-eye image frame in the nth frame 3D image signal; the same or different synthesizing modes can be adopted when one of the left-eye image frame and the right-eye image frame in the nth frame of 3D image signal and one of the left-eye image frame and the right-eye image frame in the (n + 1) th frame of 3D image signal are used for splitting and combining.
In one implementation, in order to balance the calculation amount and the improvement of the display effect in the synthesis, it is preferable that the left-eye image frame and the right-eye image frame in the nth frame 3D image signal are synthesized according to the second method, and the image frame that is not split in the nth frame 3D image signal and the relative image frame in the (n + 1) th frame 3D image signal are synthesized according to the second method. Specifically, one of a left-eye image frame and a right-eye image frame in an nth frame of 3D image signal is split into two parts, and then the two parts are combined with the left-eye image frame or the right-eye image frame which is not split to obtain 2 composite image frames; then, the relative image frame in the (n + 1) th frame of 3D image signal, which is opposite to the image frame split in the nth frame of 3D image signal, is split into two parts, and then the two parts are respectively combined with the image frame split in the nth frame of 3D image signal to obtain another 2 image frames. For example, as shown in fig. 6, a left-eye image frame in the nth frame 3D image signal is split, and a relative image frame in the n +1 th frame 3D image signal, which is opposite to the split image frame in the nth frame 3D image signal, is a right-eye image frame in the n +1 th frame 3D image signal.
It should be understood that, in the above synthesizing manners, the splitting process performed on the left-eye image frame or the right-eye image frame may be divided into a plurality of parts greater than 2, except for being equally divided into two parts, as long as all the parts together contain all the content of the image frame. Similarly, the content ratios included in the respective portions do not need to be completely uniform, and a portion may include a small content ratio and the other portion may include a large content ratio. Meanwhile, the contents contained in the respective portions may be completely different from each other, or may be allowed to partially overlap.
The content of the left-eye image frame and the content of the right-eye image frame are combined, the obtained composite image frame simultaneously contains partial content of the left-eye image frame and partial content of the right-eye image frame, and the content set of all the composite image frames contains all the content in the left-eye image frame and the right-eye image frame, and then the composite image frame is output to a polarization type 3D display screen for display. Compared with the existing shutter type 3D display technology, the method does not need heavy shutter type 3D glasses, and is lower in cost; and the content set of all the composite image frames contains all the contents in the left-eye image frame and the right-eye image frame, no image data is lost, and the image restoration effect is good. Compared with the existing polarization type 3D display technology, the method has the advantages that the synthesized image frame displayed by each image simultaneously contains partial content of the left-eye image frame and partial content of the right-eye image frame, the image brightness is higher, and the user viewing experience is better.

In one implementation, the display screen 20 is a polarized 3D LED display screen, as shown in fig. 8, and includes a display screen body 21, an LED lamp bead 22, and a polarized light mask 23. The polarization mask 23 is provided with 2 kinds of polarizers having orthogonal polarization directions. The display surface of the display screen body 21 is provided with LED lamp beads 22 arranged in an array manner, a polarized light face shield 23 is arranged, and the polarizing film of the polarized light face shield 23 covers each LED lamp bead 22.
The display screen body 21 at least comprises a printed circuit board, one side of the printed circuit board is a display surface, and the LED lamp beads 22 arranged in an array are arranged on the printed circuit board.
In another implementation manner, the display screen 20 is a polarization type 3D LED display screen, as shown in fig. 9, and includes a display screen body 21 and LED lamp beads 22' with polarizers; the LED lamp bead 22 'with the polarizing film comprises an LED lamp body 24 and a thin film polarizing film 25, and the display surface of the display screen body 21 is provided with 2 LED lamp beads 22' with polarizing films, which are arranged in an array mode and have orthogonal polarization directions.

The reason why the polarizing mask 23 is provided with 2 polarizing plates with orthogonal polarization directions or the LED package structure is packaged with 2 polarizing plates with orthogonal polarization directions is to allow the display panel 20 to output pictures with 2 orthogonal polarization directions, which correspond to the left-eye image and the right-eye image, respectively. That is, the pixels on the display screen 20 can be divided into left-eye pixels L and right-eye pixels R. The left-eye pixel points L and the right-eye pixel points R correspond to the arrangement of the polaroids in different polarization directions. It is understood that each pixel point may include 3 LEDs of different colors, or a greater number of LEDs, as required by the display color. The method is not particularly limited and may be determined according to actual conditions.
There are various arrangements of the left-eye pixels L and the right-eye pixels R on the display screen 20. In one mode, as shown in fig. 10, the left-eye pixels L and the right-eye pixels R are arranged at intervals in the longitudinal direction. In another mode, as shown in fig. 11, the left-eye pixels L and the right-eye pixels R are arranged at intervals in the horizontal direction. It will be appreciated that other arrangements, such as diagonal, may be used in addition to the arrayed lateral and longitudinal spacing.
Compared with the existing shutter type 3D display technology, the system does not need heavy shutter type 3D glasses, and is lower in cost; and the content set of all the composite image frames contains all the contents in the left-eye image frame and the right-eye image frame, no image data is lost, and the image restoration effect is good. Compared with the existing polarized light type 3D display technology, the combined image frame displayed by each image in the system simultaneously contains partial content of the left-eye image frame and partial content of the right-eye image frame, the image brightness is higher, and the user viewing experience is better.
