Abstract

A display method includes displaying, in a virtual environment, an object to which a light source is set. The method further includes illuminating an area around the object based on the light source.

First claim

What is claimed is:

1. A display method comprising:
selectively setting a spot light or a point light as a virtual source on a position in a virtual environment;
displaying, in the virtual environment, an object in the position where the virtual source is set;
extracting color values of pixels for portions of the object that correspond to positions of the virtual source of light, and
illuminating an area around the displayed object based on the set virtual source, wherein the illuminating comprises applying the color values to the virtual source, and wherein the spot light is set based on whether the virtual source influences the virtual environment with attenuation,
wherein an intensity attenuation of the virtual source from the spot light or the point light decreases at increasing distances from where the object is displayed, and
excluding an illumination effect of the virtual source on the object itself.

2. The method of claim 1 , wherein the setting comprises:
setting positions of virtual sources in a grid form on an object area of the object.

3. The method of claim 1 , further comprising:
in response to the virtual source being the spot light, setting an illuminating orientation and a position of the virtual source; and
in response to the virtual source being the spot light, setting a cut-off angle and the intensity attenuation of the virtual source, based on the illuminating orientation.

4. The method of claim 3 , wherein the illuminating comprises:
calculating the area based on the illuminating orientation and the cut-off angle.

5. The method of claim 1 , wherein the extracting comprises:
extracting, from the object as the color values, one of an average value, a weighted average value, and a median value of color values around the position of the virtual source.

6. The method of claim 1 , wherein the illuminating comprises:
controlling either one or both of a level of the illumination of the area, and a size of the illuminated area, in response to a control signal.

7. The method of claim 1 , wherein the object comprises either one or both of a still image object and a video object.

8. A display device comprising:
a display; and
a processor configured to:
selectively set a spot light or a point light as a virtual source on a position in a virtual environment,
display, on the display in the virtual environment, an object in the position where the virtual source is set,
extract color values of pixels for portions of the object that correspond to positions of the virtual source of light, and
illuminate, on the display, an area around the object based on the set virtual source,

wherein the illuminating the area comprises applying the color values to the virtual source, and
wherein the spot light is set based on whether the virtual source influences the virtual environment with attenuation,
wherein an intensity attenuation of the virtual source from the spot light or the point light decreases at increasing distances from where the object is displayed, and
excluding an illumination effect of the virtual source on the object itself.

9. The display device of claim 8 , wherein the processor is further configured to:
set any one or any combination of an illuminating orientation, a position, a cut-off angle, and the intensity attenuation of the virtual source in response to the virtual source being the spot light.

10. The display device of claim 9 , wherein the processor is configured to:
calculate the area based on any one or any combination of the illuminating orientation, the position, the cut-off angle, and the intensity attenuation.

11. The display device of claim 8 , wherein the processor is configured to:
extract, from the object as the color values, one of an average value, a weighted average value, and a median value of color values around the position of the virtual source.

12. The display device of claim 8 , wherein the processor is further configured to:
control a level of the illumination of the area in response to a control signal.

13. The display device of claim 8 , wherein:
the object comprises a video object;
the virtual environment comprises a virtual space in which the video object is provided; and
the processor is configured to apply, to the virtual source, a color of a position of the virtual source in a frame per frame of the video object.

14. The display device of claim 8 , wherein:
the object comprises a photo object;
the virtual environment comprises a virtual space in which the photo object is provided based on a predetermined arrangement; and
the processor is configured to illuminate, on the display, the virtual space based on the set virtual source.

15. The display device of claim 8 , wherein the processor is further configured to:
set a brightness of the virtual source set to the position of the object of objects in the virtual environment to be brighter than a brightness of another virtual source set to a position of another object of the objects.

16. The display device of claim 8 , wherein the display comprises any one or any combination of a head mounted display, a stereoscopic display, and a touch screen.

17. A display device comprising:
a display configured to display, in a virtual environment, an image comprising an object;
an interface configured to receive an input; and
a processor configured to:
maintain an illumination effect on the object, and change an illumination effect on surroundings of the object, in response to the input, wherein the illumination effect on the surroundings is generated by
selectively setting a spot light or a point light as a virtual source on a position in a virtual environment,
displaying, on the display in the virtual environment, the object in the position where the virtual source is set,
extracting color values of pixels for portions of the object that correspond to positions of the virtual source of light, and
illuminating, on the display, an area around the object based on the set virtual source,

wherein the illuminating comprises applying the color values to the virtual source, and wherein the spot light is set based on whether the virtual source influences the virtual environment with attenuation,
wherein an intensity attenuation of the virtual source from the spot light or the point light decreases at increasing distances from where the object is displayed, and
excluding an illumination effect of the virtual source on the object itself.

18. The display device of claim 17 , wherein the processor is configured to:
calculate the illumination effect on the surroundings of the object based on the object.

19. The display device of claim 17 , wherein the processor is configured to:
change a level of an illumination effect on the surroundings of the object by the virtual source of light from the position in the virtual environment, in response to the input.

20. The display device of claim 17 , wherein the processor is configured to:
turn on and off the illumination effect on the surroundings of the object, in response to the input.

21. A display device comprising:
a display configured to display images in frames of a video object; and
a processor configured to:
change an illumination effect on surroundings of the images per frame of the video object, during playing of the video object, wherein the illumination effect on the surroundings is generated by,
selectively setting a soot light or a point light as a virtual source on a position in a virtua
