1. A head mountable display (HMD) system comprising:
- an HMD having stereoscopic display elements for eyes of a wearer of the HMD, the stereoscopic display elements being configured to provide a virtual screen to the HMD wearer at a rendered virtual position within a three-dimensional display environment; and
a video processor configured to process video material for display by the stereoscopic display elements of the HMD;
in which the video processor is configured so that one or both of a size of the virtual screen and a distance from the wearer of the rendered virtual position of the virtual screen within the three-dimensional display environment for display of the video material by the HMD depends upon a spatial frequency content of the video material,wherein when a maximum spatial frequency is less than a threshold amount, the system is configured to display the video material on a virtual screen that appears smaller and at a selected rendered virtual position which is closer to the wearer within the three-dimensional display environment than a virtual screen on which video with a maximum spatial frequency above the threshold amount is displayed.

Abstract
A head mountable display (HMD) system in which the size and/or distance from the viewer of a virtual screen for display of video material depends upon one or more of the following:
- whether the video material is in a 2-D or a 3-D format;
- the image resolution of the video material;
- the compression quality and/or data rate of the video material;
- the aspect ratio of the video material;
- the origin of the video material; and
- metadata associated with the video material.

14. A video display system comprising:
-
a frame; at least one a pair of stereoscopic display elements coupled to the frame to provide a three-dimensional display environment; and a video processor arranged in operative communication with the pair of stereoscopic display elements, in which the video processor is configured to generate video material for display, one or both of an image size and a rendered image position within the three-dimensional display environment at which the video material is displayed depending upon an image resolution of the video material and spatial frequency content of the video material, wherein if a maximum spatial frequency is less than a threshold amount, then the video material is configured by the video processor for display on a virtual screen associated with the pair of stereoscopic display elements, the virtual screen configured to appear smaller and at a selected rendered position within the three-dimensional display environment which is closer to a user than a virtual screen on which video with a maximum spatial frequency above the threshold amount is configured for display.

15. A method of operation of a stereoscopic head mountable display (HMD) system operable to provide a three dimensional display environment, comprising:
-
rendering a virtual screen for display of video material to a viewer of the HMD system, in which one or both of a size and rendered virtual distance from the viewer of the virtual screen within the three-dimensional display environment depends upon spatial frequency content of the video material; determining, by one or more processors, whether a maximum spatial frequency is less than a threshold amount; and when the maximum spatial frequency is determined to be less than the threshold amount, displaying the video material on a virtual screen that appears smaller and at a selected rendered virtual position within the three-dimensional display environment which is closer to the viewer than a virtual screen on which video with a maximum spatial frequency above the threshold amount is displayed. - View Dependent Claims (17)

16. A method of operation of a stereoscopic video display operable to provide a three-dimensional display environment, in which one or both of an image size and a rendered image position within the three-dimensional display environment at which video material is displayed depends upon an image resolution of the video material and spatial frequency content of the video material, the method comprising:
-
determining, by one or more processors, whether a maximum spatial frequency is less than a threshold amount; and upon determination that the maximum spatial frequency is less than the threshold amount, preparing the video material for display on a virtual screen that appears smaller and at a selected rendered position within the three-dimensional display environment which is closer to a user of the video display than a virtual screen on which video with a maximum spatial frequency above the threshold amount is displayed.
