Image processing method, image processing device and display device

Abstract

The invention discloses an image processing method, an image processing device and a display device, relates to the technical field of image processing, and aims to improve the utilization efficiencyof a graphic processor and reduce the delay of a VR image displayed by VR display equipment. The image processing method comprises the steps of counting the rendering duration of M frames of images; judging whether the rendering duration of the M frames of images is matched with a motion attitude requirement or not; if yes, controlling the difference value t between the rendering starting moment of each frame of image and the distortion processing starting moment of the corresponding frame of image to be smaller than or equal to a preset difference value taim; itherwise, setting a system framefrequency, and enabling the rendering duration of each frame of image to be matched with the motion attitude requirement. The image processing device comprises the image processing method. The imageprocessing method, the image processing device and the display device are used for image processing.

Description

technical field [0001] The present invention relates to the technical field of image processing, in particular to an image processing method, an image processing device, and a display device. Background technique [0002] Virtual reality technology (Virtual Reality, abbreviated as VR) is a computer simulation method that can create and experience a virtual world. When performing VR display, users can immerse themselves in the immersive environment provided by VR display, bringing users a more realistic experience. [0003] In order to reduce the VR image delay, the Asynchronous Time Warp (abbreviated as ATW) technology is generally used, which is an intermediate frame generation method that arranges the image rendering process and the time warp (abbreviated as TW) process in two threads. , which can effectively reduce image delay and alleviate the problem of head vertigo caused by VR image delay. At present, when the complexity of the scene displayed in the immersive envir...

AI Technical Summary

Problems solved by technology

At present, when the complexity of the scene displayed in the immersive environment provided by the VR display device is relatively low, the required rendering time is relatively short, but the time when the graphics processor completes the image rendering is relatively late, resulting in TW processing of the next frame. The waiting time of the process is relatively long; and when the scene complexity displayed by the immersive environment provided by the VR display device is relatively high, the required rendering time is relatively long, resulting in a relatively long time for the graphics processor to render the image, making the image The Time Warp (TW for short) processing is carried out in time, resulting in the delay of the VR image displayed on the VR display device, so that when the user’s head posture changes rapidly, the VR image seen by the user will shake, and then the head will appear. vertigo problem
