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, further discussion thereof is not required in subsequent figures.
Fig. 1 illustrates a flow diagram of some embodiments of a display method of pictures of the present disclosure.
As shown in fig. 1, the method includes: step 110, judging whether to output a picture through a video layer module; step 120, generating a video Surface and a graphic Surface; and step 130, sending the video Surface and the graphic Surface. For example, steps 110-130 may be performed by a SurfaceFlinger unit.
In step 110, it is determined whether the graphics cache of the acquired target picture is marked for output by a video layer module of the display system. For example, the graphics cache is of the graphics buffer data type.
In some embodiments, the graphics cache is generated from a texture generated by the GPU, the texture is generated for the GPU from the decoded target picture, and the decoding process maintains the original size of the target picture. For example, the target picture may be a picture in JPEG (Joint Photographic Experts Group) or PNG (Portable network graphics) format with 4K resolution.
In some embodiments, before the faceflicker unit performs step 110, the target picture may be decoded while maintaining the original picture size of the target picture; the GUP renders the decoded target picture to generate Texture (Texture); binding the texture to the graph cache; in order to ensure that the target picture can be displayed at the resolution of 4K, a graphics processing application program can be developed to mark the graphics cache as being output through a video layer module of the display system, and notify the Surface flicker unit that the Surface needs to be overlaid.
In step 120, in the case that the graphics cache is marked to be output by the video layer module, a plurality of graphics surfaces with the same video Surface and content are generated according to the graphics cache. For example, the Surface flunger unit may superimpose graphic buffers corresponding to a plurality of graphic surfaces onto a FrameBuffer, and the video surfaces may be directly sent to the video layer module without being superimposed.
In some embodiments, step 120 may be implemented by the embodiment of fig. 2.
Fig. 2 illustrates a flow diagram of some embodiments of step 120 of fig. 1.
As shown in fig. 2, step 120 may include: step 1210, buffering the superposition frame; and a step 1220 of converting the video format.
In step 1210, a plurality of graphical surfaces are overlaid to FrameBuffer.
In step 1220, the content in the FrameBuffer is converted into a video format supported by the video VDP. For example, the ARGB8888 format is converted to the YUV420SP format.
In some embodiments, multiple graphics surfaces may be overlaid on the frame buffer through the HWC of the Surface flunger unit and the content of the frame buffer is converted into a VDP-supported video format.
Then, the conversion result and the video Surface can be sent to the VDP, so that the VDP mixes the conversion result and the video Surface into the target video and outputs the target video. For example, the video Surface is a video with a resolution of 4K, and the conversion result is amplified to a resolution of 4K by VDP and mixed with the video Surface. The target video can be generated by mixing the conversion result and the video Surface through an online superimposer for the VDP.
In some embodiments, the VDP sends the target video to a display device (such as a television or the like) supporting 4K resolution for display through HDMI, thereby realizing lossless display of the target picture.
Fig. 3 illustrates a block diagram of some embodiments of a display device of pictures of the present disclosure.
As shown in fig. 3, the display device 3 of pictures includes a judgment unit 31, a generation unit 32, and a transmission unit 33.
The judgment unit 31 judges whether the acquired graphic buffer of the target picture is marked to be output by a video layer module of the display system. For example, the graphics cache is generated according to a texture generated by the GPU, the texture is generated for the GPU according to the decoded target picture, and the decoding process maintains the original size of the target picture. The graphics cache is of the graphics buffer data type.
The generating unit 32 generates a plurality of graphics surfaces having the same video Surface and content from the graphics cache in a case where the graphics cache is marked to be output through the video layer module. The sending unit 33 sends the video Surface and the multiple graphics surfaces to the video layer module, so that the video layer module mixes the video Surface and the multiple graphics surfaces into a target video and outputs the target video.
In some embodiments, the display device 3 of pictures further comprises a conversion unit 34.
The conversion unit 34 superimposes a plurality of graphics surfaces on the frame buffer, and converts the content in the frame buffer into a video format supported by VDP. For example, the conversion unit 34 superimposes a plurality of graphics surfaces on the frame buffer through the HWC, and converts the contents of the frame buffer into a video format supported by the VDP.
The transmission unit 33 transmits the conversion result and the video Surface to the VDP, so that the VDP mixes the conversion result and the video Surface into a target video and outputs the target video. For example, the video Surface is a video with a resolution of 4K, and the conversion result is amplified to a resolution of 4K by VDP and mixed with the video Surface. The target video can be generated by mixing the conversion result and the video Surface through an online superimposer for the VDP.
In the embodiment, the target picture to be displayed is converted into a video format, and the video layer module with the capability of processing the high-resolution video outputs and presents the target picture, so that the target picture can be displayed in a lossless manner, and the definition of picture display is improved.
