Abstract

A method of displaying an illumination includes: based on illumination information, determining, using a least one processor, an illumination area to which an illumination assigned in a virtual space is projected; and visualizing, using the at least one processor, an illumination effect produced by the illumination with respect to a determined boundary area in the illumination area, the determined boundary area including a boundary and a portion of the determined illumination area that is less than all of the determined illumination area.

First claim

What is claimed is:

1. A method of displaying an illumination, the method comprising implementing at least one processor to:
determine, based on illumination information, an illumination area produced by an illumination source in a virtual space and projected to a layer of the virtual space corresponding to a viewpoint of a scene displayed by a display device, wherein the illumination area is a triangular area including a first vertex corresponding the illumination source, and second and third vertexes defining a base surface;
determine a boundary area in the illumination area, wherein the boundary area comprises a boundary and outer portions of the illumination area that are less than all of the illumination area and extend adjacent to the boundary from the first vertex to the base surface;
generate, by overlaying the layer on the scene, an illumination effect produced by the illumination source in the boundary area; and
control the display device to display the illumination effect.

2. The method of claim 1 , wherein the determining of the illumination area comprises:
determining the illumination area based on at least one of a position, a threshold angle, a direction, an intensity, or a color included in the illumination information.

3. The method of claim 1 , wherein the generating of the illumination effect comprises increasing a brightness of a pixel in the boundary area compared to a brightness of a pixel outside the boundary area in the illumination area.

4. The method of claim 1 , wherein the generating of the illumination effect comprises determining incremental levels of brightness for pixels in the boundary area, based on respective distances between the pixels and the illumination source, and respective distances between the pixels and the boundary.

5. The method of claim 1 , wherein the generating of the illumination effect comprises fitting, to the illumination area, a brightness adjustment map to define incremental levels of brightness for pixels in the boundary area in a predetermined form.

6. The method of claim 1 , wherein the generating of the illumination effect comprises extending the boundary area in response to an overlap between the boundary area and another boundary area of another illumination source.

7. The method of claim 1 , wherein the generating of the illumination effect comprises:
in response to an overlap between the boundary area and another boundary area of another illumination source, adjusting a brightness and a color of the boundary area by overlapping a brightness and a color of the another boundary area in an overlapping area of the boundary area and the another boundary area.

8. The method of claim 1 , wherein the generating of the illumination effect comprises:
in response to an overlap between the boundary area and another boundary area of another illumination source, assigning a weight to respective incremented levels of brightness for pixels in an overlapping area of the boundary area and the another boundary area.

9. A non-transitory computer readable medium storing instructions that, when executed by a processor, cause the processor to perform the method of claim 1 .

10. A device for displaying an illumination, the device comprising:
a display; and
at least one processor configured to
determine, based on illumination information, an illumination area produced by an illumination source in a virtual space and projected to a layer of the virtual space corresponding to a viewpoint of a scene displayed by the display, wherein the illumination area is a triangular area including a first vertex corresponding the illumination source, and second and third vertexes defining a base surface,
define a boundary area in the illumination area, wherein the boundary area comprises a boundary and outer portions of the illumination area that are less than all of the illumination area and extend adjacent to the boundary from the first vertex to the base surface,
generate, by overlaying the layer on the scene, an illumination effect produced by the illumination source in the boundary area, and
control the display to display the illumination effect.

11. The device of claim 10 , wherein the at least one processor is further configured to generate the illumination effect by increasing a brightness of a pixel in the boundary area compared to a brightness of a pixel outside the boundary area in the illumination area.

12. The device of claim 10 , wherein the at least one processor is further configured to generate the illumination effect by determining incremental levels of brightness for pixels in the boundary area based on respective distances between the pixels and the illumination source, and respective distances between the pixels and the boundary.

13. The device of claim 10 , wherein the at least one processor is further configured to generate the illumination effect by fitting, to the illumination area, a brightness adjustment map to define incremental levels of brightness for pixels in the boundary area in a predetermined form.

14. The device of claim 10 , wherein the at least one processor is further configured to generate the illumination effect by extending the boundary area in response to an overlap between the boundary area and another boundary area of another illumination source.

15. The device of claim 10 , wherein the at least one processor is further configured to generate the illumination effect by adjusting a brightness and a color of the boundary area by overlapping a brightness and a color of another boundary area of another illumination source in an overlapping area of the boundary and the another boundary area, in response to an overlap between the boundary area and the another boundary area.

16. The device of claim 10 , wherein the at least one processor is further configured to generate the illumination effect by assigning a weight to respective incremented levels of brightness for pixels in an overlapping area of the boundary area and another boundary area of another illumination source, in response to an overlap between the boundary area and the another boundary area.

17. A method of displaying an illumination, the method comprising:
determining, by at least one processor,
a first illumination area corresponding to light projected by a first light source, wherein the first illumination area is a first triangular area including a first vertex corresponding the first light source, and second and third vertexes defining a first base surface,
