Problems solved by technology

[0003] In related technologies, multi-threading is used to render the left and right eyes separately or half-frame processing for the left and right eyes. However, due to the performance limitations of the system and hardware, the image rendering time is too long, resulting in serious frame drop of the picture, causing a strong sense of dizziness, and the experience effect is extremely good.

Abstract

The invention discloses an image rendering method and device. The method comprises the steps that a first thread renders a first image corresponding to a current frame; and the second thread generatesa first prediction image corresponding to the current frame according to the first image corresponding to the current frame, and the first prediction image and the first image correspond to the samedisplay screen; and the first thread obtains a second prediction image corresponding to the previous frame, and the first image and the second prediction image respectively correspond to different display screens; and the first thread displays the first image and the second predicted image on different display screens respectively. Therefore, the prediction image of the previous frame and the rendered image of the current frame are used as the display image of the current frame, so that the technical effect of improving the image display frame rate is achieved, and the technical problem of frame dropping of high-frame-rate image rendering in the prior art is solved.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an image rendering method and device thereof. Background technique [0002] In VR (Virtual Reality, virtual reality) display technology, by continuously refreshing the display images on the left and right eye screens according to the posture data, users can have a sense of virtual reality experience, and the higher the frame rate of the display images on the screen, the more realistic the virtual reality effect . [0003] In related technologies, multi-threading is used to render the left and right eyes separately or half-frame processing for the left and right eyes. However, due to the performance limitations of the system and hardware, the image rendering time is too long, resulting in serious frame drop of the picture, causing a strong sense of dizziness, and the experience effect is extremely good. Difference. Contents of the invention [0004] The presen...
