Classification: CPC G  H | IPC G

Claim 0:
1. A method of controlling a display device, the method comprising:
rendering a plurality of viewpoint images;
generating a plurality of sub-images based on the plurality of viewpoint images and a plurality of mapping pattern images corresponding to the plurality of viewpoint images,
wherein each of the plurality of sub-images corresponds to one of the plurality of mapping pattern images, and each of the plurality of mapping pattern images corresponds to one of the plurality of viewpoint images,
wherein generating the plurality of sub-images comprises:
loading the plurality of mapping pattern images, wherein the plurality of mapping pattern images are previously stored; and
for each sub-image, calculating a color value based on a color value of a particular pixel position in the corresponding viewpoint image among the plurality of viewpoint images and on a color value of a particular color region corresponding to the particular pixel position in the corresponding mapping pattern image among the plurality of mapping pattern images;

generating a single light-field image by merging the plurality of sub-images; and
outputting the single light-field image.
