CLAIMS

1. A method of generating stereoscopic images for display with respect to a virtual display screen (VDS) position, the method comprising the steps of:

setting a VDS position for a stereoscopic image for display such that a depth profile of one or more VDSs approximates a depth profile of one or more objects in a virtual scene to be displayed by that stereoscopic image; and

generating the stereoscopic image for display having image parallax appropriate to the VDS position or positions set by the setting step,

wherein the VDS position is defined such that a contact point between an associated object and another object within the image is a zero-disparity point.

2. A method according to claim 1 , wherein the stereoscopic image is to be displayed using an equirectangular projection.

3. A method according to claim 1 , wherein one or more objects are associated with a single VDS.

4. A method according to claim 3, wherein the one or more objects are objects that are stationary within the virtual scene.

5. A method according to claim 1 , comprising associating a VDS with a single moving object within the virtual scene.

6. A method according to claim 1 , comprising defining one or more VDSs to be movable within a virtual scene.

7. A method according to claim 6, wherein the motion of the one or more VDSs is dependent on the motion of the object associated with the VDS.

8. A method according to claim 1 , wherein the VDS has a shape defined by a three-dimensional function or a mesh.

9. A method according to claim 1 , comprising defining one or more VDSs to correspond to objects in dependence upon a gaze direction of a viewer of the stereoscopic images.

10. A method according to claim 1 , comprising describing differences between the depth profile of the VDS and an associated object using a depth map.

1 1. A method according to claim 10, wherein the display of the object is dependent upon the depth map, such that the motion of the object in response to a change in viewpoint is

proportional to the difference between the depth profiles.

12. Computer software which, when executed by a computer, causes the computer to execute the method of claim 1.

13. An image generation system for generating stereoscopic images for display with respect to a virtual display screen (VDS) position, the system comprising:

a VDS setting unit configured to set the VDS position for a stereoscopic image for display such that a depth profile of the VDS approximates a depth profile of objects to be displayed in that stereoscopic image; and

an image generation unit operable to generate the stereoscopic image for display having image parallax appropriate to the VDS position set by the VDS setting unit;

wherein the VDS position is defined such that a contact point between an associated object and another object within the image is a zero-disparity point.

14. A system according to claim 13, comprising a head-mountable display unit operable to display the generated stereoscopic images.

15. A stereoscopic video signal having associated metadata defining a virtual display screen (VDS) position for use in respect of subsets of frames of the stereoscopic video signal, the VDS position for a frame having depth profile that approximates the depth profile of objects to be displayed by that frame and wherein the VDS position is defined such that a contact point between an associated object and another object within the image is a zero-disparity point.
