Embodiment Construction

[0311] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings.

[0312] A preferred embodiment of the invention relates to providing frames (images) for display to a Virtual Reality (VR) and / or Augmented Reality (AR) Head Mounted Display (HMD) system.

[0313] Such a system can be as figure 1 Configured as shown (and as described above), the display 8 of the system comprises a suitable head-mounted display comprising, inter alia, a display screen or display screens ( panel or panels), one or more lenses in the viewing path between the user's eyes and the display, and a lens for tracking the position of the user's head in use (while the image is being displayed to the user on the display) (orientation (posture)) (and / or its viewing (line of sight) direction).

[0314] Figure 5 An exemplary virtual reality (VR) head-mounted display 50 is schematically shown. Such as Figure 5 As shown, the head mounted display 50 in...

Abstract

The invention provides a graphics processing system. In addition to rendering a first frame representing a first forward view of a scene, a graphics processing system renders one or more further versions of the first frame, each representing a further view of the scene based on a different point in time and / or view orientation. The first frame and / or one or more of the one or more further versionsmay then be subjected to ''timewarp'' and / or ''spacewarp'' processing to generate an output ''timewarped'' and / or ''spacewarped'' image for display.

Description

technical field [0001] The present invention relates to graphics processing systems, and in particular to graphics processing systems that provide images for display to virtual reality (VR) and / or augmented reality (AR) (head-mounted) display systems. Background technique [0002] figure 1 An exemplary system-on-chip (SoC) graphics processing system 10 is shown comprising a main processor including a central processing unit (CPU) 1 , a graphics processing unit (GPU) 2 , a display controller 4 and a memory controller 6 . The exemplary graphics processing system 10 may further include a video engine 3 . Such as figure 1 These units communicate via interconnect 5 and have access to off-chip memory 7 as shown. In this system, a graphics processing unit (GPU) 2 will render frames (images) to be displayed, and a display controller 4 will then provide the frames to a display panel 8 for display. [0003] When using the system, for example an application such as a game executing...
