Embodiment 1

[0077] refer to figure 1 , shows a flowchart of steps of a display method provided by an embodiment of the present invention. The methods include:

[0078] Step 101, determine the rendering speed of scene rendering.

[0079] In this embodiment, depending on the performance of the processor, the complexity of the VR application scene, etc., the rendering speed of the rendering thread when rendering the scene is different. For example, the application scene is more complex, and the rendering thread is slower when rendering the scene; the application scene is simple, and the rendering thread is faster when rendering the scene. Determine the rendering speed of scene rendering, specifically, within a set period of time, count the rendering time of each frame of the scene when rendering the scene, and determine the average rendering time of one frame of pictures. For example, to render 100 frames, count the rendering time t1, t2, t3...t100 of each frame when rendering the scene, ...

Embodiment 2

[0100] refer to Figure 4 , shows a flowchart of steps of a display method provided by an embodiment of the present invention. The methods include:

[0101] Step 201, determine the rendering speed of scene rendering.

[0102] Step 202, judging whether to enable an asynchronous time warp ATW thread according to the rendering speed.

[0103] Step 203, when it is determined that the ATW thread is not enabled, use the rendering thread to obtain the first scene data during the display of a frame, and run the rendering thread to The first scene data is corrected to obtain the first corrected scene data.

[0104] Step 204, displaying according to the first modified scene data.

[0105] Step 205, when it is determined that the ATW thread is enabled, during the display process of a frame, use the rendering thread to obtain the second scene data, run the ATW thread to correct the second scene data, and obtain the second scene data. 2. Modify the scene data.

[0106] In this embodi...

Embodiment 3

[0119] refer to Figure 5 , shows a structural block diagram of a display device provided by an embodiment of the present invention. The devices include:

[0120] A rendering speed determining module 301, configured to determine the rendering speed of scene rendering;

[0121] A judging module 302, configured to judge whether to enable an asynchronous time warping ATW thread according to the rendering speed;

[0122] The first rendering and correction module 303 is configured to use the rendering thread to obtain the first scene data during the display process of one frame of the picture when it is determined that the ATW thread is not enabled, and when it is determined that the rendering of the first scene data is completed , running the rendering thread to correct the first scene data, and obtaining the first corrected scene data;

[0123] The first display module 304 is configured to display according to the first modified scene data.

[0124] Optionally, the rendering ...

Abstract

The present invention provides a display method and apparatus. The method comprises the following steps of: determining a rendering speed of scene rendering; Judging whether to start an asynchronous time distorted ATW thread according to the rendering speed; When the ATW thread is judged not to be started, obtaining the first scene data in a frame picture display process by using a rendering thread; when the first scene data rendering is determined to be completed, running the rendering thread to correct the first scene data and obtain the first modified scene data; displaying according to thefirst correction scene data. The embodiment of the invention gives consideration to the performance of different processors and the complexity of VR application scene, the phenomenon of picture jitter can be reduced, the sense of vertigo of the user can be alleviated, the system power consumption can be reduced, the delay between scene rendering and display can be reduced, and the user experiencecan be improved.

Description

technical field [0001] The present invention relates to the field of display technology, in particular to a display method and device. Background technique [0002] VR (Virtual Reality, virtual reality) technology is an emerging information technology. It can generate a specific range of virtual environment with realistic visual, auditory and tactile integration. When the user interacts with the VR device, the user can have an immersive feeling and experience. [0003] VR technology requires VR applications to maintain a high frame rate to provide the best rendering quality. When the VR application cannot maintain a sufficient frame rate, the game screen may shake and cause users to feel dizzy. Nowadays, the Asynchronous Time Warp (ATW) technology is often used to reduce the jitter phenomenon of the picture, however, although the ATW technology reduces the dizziness, it increases the power consumption of the system. Contents of the invention [0004] The invention prov...
