Adjusting video rendering rate of virtual reality content and processing of a stereoscopic image

Abstract

An example technique may include performing, by a virtual reality application provided on a computing device, video rendering at a first video rendering rate based on updating an entire image on a screen of the computing device at a first update rate, determining that a performance of the video rendering is less than a threshold, performing, based on the determining, video rendering at a second video rendering rate by updating a first portion of the image at the first update rate, and by updating a second portion of the image at a second update rate that is less than the first update rate. Another example technique may include shifting, during an eye blinking period, one or both of a left eye image and a right eye image to reduce a disparity between a left viewed object and a right viewedobject.

[0003] This specification relates to image processing and rendering of virtual reality content, and more specifically, to technology for adjusting video rendering rate of virtual reality content based on rendering performance and processing of stereoscopic images. Background technique

[0004] Performing video rendering consumes significant computing resources. In some cases, multiple applications running on a computing device may share computing resources, which can degrade the performance of one or more applications.

[0005] Furthermore, in the real world, there is very little conflict between accommodation and convergence demands. However, for VR (Virtual Reality) images or stereoscopic images displayed on a sc...
