Abstract

There is provided an image processing device and method that can suppress degradation in the stereoscopic effect and visibility of a stereoscopic image and suppress an accommodative-convergence conflict. Scaling transformation is performed on a stereoscopic object according to the angle of a display surface with respect to a horizontal plane of a real space, a stereoscopic image to be displayed on the display surface is generated by using the stereoscopic object having been subjected to the scaling transformation, and the stereoscopic image is displayed on the display surface. The present disclosure can be applied to, for example, an image processing device, an electronic device, an image processing method, or a program or the like.

First claim

1 . An image processing device comprising: a scaling transformation unit that performs scaling transformation on a stereoscopic object according to an angle of a display surface with respect to a horizontal plane of a real space;
an image generation unit that generates a stereoscopic image to be displayed on the display surface, by using the stereoscopic object having been subjected to the scaling transformation; and a display control unit that displays the stereoscopic image on the display surface.

2 . The image processing device according to claim 1 , wherein the scaling transformation unit scales down the stereoscopic object as the angle decreases, whereas the scaling transformation unit scales up the stereoscopic object as the angle increases.

3 . The image processing device according to claim 2 , wherein the scaling transformation unit performs the scaling transformation in a predetermined range of the angle.

4 . The image processing device according to claim 1 , wherein the scaling transformation unit performs the scaling transformation such that the stereoscopic object is placed in the display surface when viewed from an eyepoint position of an observer.

5 . The image processing device according to claim 1 , wherein the scaling transformation unit performs the scaling transformation to keep a ratio of a height and a width of the stereoscopic object.

6 . The image processing device according to claim 1 , wherein the scaling transformation unit performs the scaling transformation only in a height direction of the stereoscopic object.

7 . The image processing device according to claim 1 , further comprising a display unit that has the display surface and a structure forming the angle; and
an angle detection unit that detects the angle formed by the structure, wherein the scaling transformation unit performs the scaling transformation according to the angle detected by the angle detection unit.

8 . The image processing device according to claim 7 , wherein the structure allows the display surface to pivot about one end of the display surface.

9 . The image processing device according to claim 7 , wherein the structure allows the display surface to pivot about a position other than one end of the display surface.

10 . The image processing device according to claim 7 , further comprising: an angle setting unit that sets the angle; and
an angle control unit that drives the structure such that the angle agrees with an angle set by the angle setting unit.

11 . The image processing device according to claim 10 , wherein the angle setting unit sets the angle according to the stereoscopic object.

12 . The image processing device according to claim 11 , wherein the angle setting unit sets the angle according to a ratio of a depth and a height of the stereoscopic object.

13 . The image processing device according to claim 12 , wherein the angle setting unit sets the angle smaller as the depth is larger relative to the height.

14 . The image processing device according to claim 10 , wherein the angle control unit drives the structure such that the angle is equal to or larger than a predetermined angle.

15 . The image processing device according to claim 1 , further comprising a clipping unit that clips the stereoscopic object according to the angle and an eyepoint position of an observer of the stereoscopic image.

16 . The image processing device according to claim 15 , wherein the clipping unit clips the stereoscopic object on a plane connecting a fiducial point at a position closer to the display surface than the eyepoint position and one end of the display surface.

17 . The image processing device according to claim 15 , wherein the clipping unit clips the stereoscopic object on a vertical plane or a horizontal plane of a real space or each of the planes, the plane passing through one end of the display surface.

18 . The image processing device according to claim 1 , further comprising an eyepoint position detection unit that detects an eyepoint position of an observer of the stereoscopic image,
wherein the image generation unit generates the stereoscopic image on a basis of the eyepoint position.

19 . The image processing device according to claim 1 , wherein the image generation unit
renders the stereoscopic object, generates virtual eyepoint images for both eyes when viewed from an eyepoint position of an observer of the stereoscopic image, and transforms the virtual eyepoint images to the stereoscopic image to be displayed on the display surface.

20 . An image processing method comprising: performing scaling transformation on a stereoscopic object according to an angle of a display surface with respect to a horizontal plane of a real space;
generating a stereoscopic image to be displayed on the display surface, by using the stereoscopic object having been subjected to the scaling transformation; and displaying the stereoscopic image on the display surface.
