Abstract
A method for combining a real space image with a virtual image, includes: causing an imaging unit to capture an image of a real space; generating an image covering a predetermined space based on a plurality of real images in the captured real space; extracting position information of a light source based on the generated image; and adding a light source or a shadow on the virtual image based on the extracted position information of the light source.
