Detailed Description
The technical solutions in the present application will be described clearly and completely with reference to the drawings in the present application, and it should be understood that the described embodiments are only a part of the embodiments of the present application, and not all of the embodiments. The components of the present application, as generally described and illustrated in the figures herein, may be arranged and designed in a wide variety of different configurations. Thus, the following detailed description of the embodiments of the present application, as presented in the figures, is not intended to limit the scope of the claimed application, but is merely representative of selected embodiments of the application. All other embodiments, which can be derived by a person skilled in the art from the embodiments of the present application without making any creative effort, shall fall within the protection scope of the present application.
It should be noted that: like reference numbers and letters refer to like items in the following figures, and thus, once an item is defined in one figure, it need not be further defined or explained in subsequent figures. Meanwhile, in the description of the present application, the terms "first", "second", and the like are used only for distinguishing the description, and are not to be construed as indicating or implying relative importance.
The shutter 3D display technology mainly achieves a 3D effect by increasing a fast refresh rate of a picture, usually at least 120Hz, and belongs to an active 3D technology. After the 3D signal is inputted to a display device such as a monitor, a projector, etc., the 120Hz image is alternately generated in a frame sequence format, the frame signals are transmitted by an infrared transmitter, the receiving 3D glasses are responsible for viewing the corresponding images by the left and right eyes in refresh synchronization, and the same frame number as the 2D video image is maintained, the two eyes of the user see different pictures which are rapidly switched, and an illusion is generated in the brain, so that the stereoscopic image can be viewed.
However, in the above-mentioned most original shutter-type 3D display scheme, if the display directly displays images in a left-right frame alternating manner, crosstalk between the left-eye image and the right-eye image is easily caused, thereby causing image aliasing and vertigo, specifically, taking a progressive scanning refreshed display as an example, on the display, images to be played are sequentially refreshed from top to bottom, wherein the images to be played are played and displayed in a left-right alternating manner, that is, a left-eye image is refreshed from top to bottom first, when the refreshing display of the left-eye image is completed, a right-eye image is refreshed from top to bottom, and in the process of refreshing and displaying the right-eye image, because the left-eye image and the right-eye image are refreshed from top to bottom, the left-eye image and the right-eye image are in the same frame, for receiving the left-eye image, the left-eye image is aliased after the refreshing is completed, and in the original left-right alternating played image, once the refreshing of the left-eye image is completed, the right-eye image is refreshed, thereby causing crosstalk between the left-eye image and the vertigo.
In contrast, with the development of the technology, in some subsequent improved technologies, a frame of completely black image or a frame of repeated image is separately inserted between the images for displaying the left eye and the right eye in an alternating manner, and then a shutter switch in the 3D glasses is matched to avoid image crosstalk between the left eye and the right eye, thereby solving the problem of image aliasing.
However, in the above technical improvement, by inserting one frame of completely black image or one frame of repeated image between the left-eye image and the right-eye image in the alternate playing mode, the effective frame rate is only 25% of the output frame rate of the display, taking the display outputting 120 frames of images as an example, since 120 frames of images need to be distinguished between the left eye and the right eye, the frame rate experienced by the left eye and the right eye is only 60 frames, and if one frame of completely black image or one frame of repeated image is inserted in the left eye and the right eye switching process, the frame rate experienced by the left eye and the right eye is only 30 frames, so the effective frame rate and the viewing experience of the images are greatly reduced.
In view of the above, referring to fig. 1, the present application provides a method for playing a stereoscopic image, which is used for playing the stereoscopic image, and the technical scheme specifically includes:
s110, obtaining effective image data;
s120, adding black data to the effective image data to obtain a playing image, and setting the effective image data and the black data in the playing image in a layered mode;
and S130, refreshing and playing the effective image data and the black data in sequence.
The sequential refreshing and playing of the effective image data and the black data refers to refreshing the black data or the effective image data after the effective image data or the black data is refreshed, because the effective image data and the black data are arranged in a layered manner, the layering referred to herein generally refers to layering from top to bottom, and because the refreshing of the display is generally sequential refreshing from top to bottom.
The black data is usually referred to as black pixels for filling, and may also be referred to as pixels or images of other colors, which is the biggest difference compared with the conventional prior art playing technology, in that the present application adds the black data in a broad sense to the original effective image data.
It should be noted that, in the solution of the present application, black data is added to effective image data to obtain a playing image, that is, when the effective image data is refreshed and played, the effective image data and the black data are in the same frame, so as to avoid refreshing a frame of black data after refreshing a frame of effective image data, thereby improving the effective display frame rate.
The effective image data and the black data in the playing image are layered, so that after the effective image data is refreshed, the time for refreshing the black data exists, the refreshed black data can be the black data of the current playing image or the black data of the next playing image, a time interval exists because the black data needs to be refreshed, and the effective image data is complete in the time interval, so that the playing image is displayed in such a way.
Further, in some embodiments, the step of adding black data to the effective image data to obtain the playing image includes;
and adding black data above and/or below the effective image data to obtain a played image.
In general, the display sequentially refreshes the image from top to bottom, and thus, black data may be added above and/or below the effective image data.
The effective image data includes left-eye effective data and right-eye effective data, and the position of the black data added to the left-eye effective data is the same as the position of the black data added to the right-eye effective data, that is, when the black data is added to the upper position in the left-eye effective data, the black data should be added to the upper position in the right-eye effective data.
Further, in some embodiments, the step of adding black data to the effective image data to obtain the played image includes;
scaling the effective image data;
black data is added to the scaled empty region.
In general, since the size of the display is fixed, when adding black data to effective image data, the effective image data may be first scaled, specifically, the effective image data may be reduced, and the reduced effective image data may form an empty region compared to the original effective image data, and the empty region may be filled with the black data.
Further, when the effective image data is reduced, the reduction may be performed only in the height direction of the effective image data, that is, only above and/or below the effective image data, and then the blank region may be filled with the black data.
Further, in some embodiments, the playing image includes a left-eye image and a right-eye image, one effective image data includes a left-eye effective data and a right-eye effective data, and the step of sequentially refreshing and playing the effective image data and the black data includes:

The left-eye image and the right-eye image are played in an alternating playing mode, the left-eye image comprises left-eye effective data and black data, and the right-eye image comprises right-eye effective data and black data.
Specifically, in some embodiments, the process of sequentially refreshing and playing the effective image data and the black data is as follows:

or the like, or, alternatively,
and refreshing and playing the black data, the left eye effective data, the black data, the right eye effective data and the black data in sequence.
Further, in some embodiments, the step of sequentially refreshing and playing the valid image data and the black data includes:
reducing the playing brightness when refreshing and playing the effective image data;
when the black data is refreshed and played, the playing brightness is improved.
In the scheme of the application, the glasses are controlled to be closed at the moment, so that the image frame cannot be received at the moment, the playing brightness can be reduced to reduce the power consumption, and when the black data is refreshed and played, because the black data and the effective image data are arranged in a layered mode, the effective image data is refreshed and is the complete effective image data, the glasses are controlled to be opened at the moment, the image frame is received, and the playing brightness is improved at the moment.
In a second aspect, referring to fig. 2, the present application further provides a stereoscopic image receiving method, configured to receive a playing image, where one playing image includes effective image data and black data, and the effective image data and the black data are layered, and the method includes:

Specifically, the playing image includes a left-eye image and a right-eye image, the effective image data includes left-eye effective data and right-eye effective data, and when the black data is refreshed and played, the step of opening the left-eye glasses or the right-eye glasses includes:

When the refreshing of the black data below the left eye image is finished, the display starts to refresh the black data above the right eye image from top to bottom, the time for refreshing the black data above the right eye image is t4, the left eye glasses are still in an open state within the time t4, when the refreshing of the black data above the right eye image is finished and the refreshing of the effective data of the right eye is started, the left eye glasses are controlled to be closed, the time for refreshing the effective data of the right eye image is t5, within the time t5, the left eye glasses and the right eye glasses are both in a closed state, after the refreshing of the effective data of the right eye is finished, the refreshing of the black data below the right eye image is started, the time for refreshing the black data below the right eye image is t6, within the time t6, the right eye glasses are controlled to be opened, at the moment, the right eye glasses receive the effective data of the right eye, after the time t6, the refreshing of the next left eye image is started, the image is shown in fig. 7, within the time t7, the right eye glasses are still in an open state, within the time t8, the right eye glasses are controlled to be closed, namely, within the time, the time of the left eye glasses and the left eye glasses are both in a state, and the left eye glasses are controlled to receive the effective data, so that the left eye glasses are opened, and the left eye glasses are controlled within the time t 9.
