Abstract: A method of generating a stereogram is disclosed. The method includes a first step of partially rendering a preset region of each of a plurality of images having different views to a memory, a second step of extracting a pixel at a corresponding location of the rendered preset region to generate a hogel image, and a third step of repeatedly performing the first step and the second step on a remaining region of each of the plural images to generate a hogel image sequence. Accordingly the stereogram generation method effectively generates a stereogram having high resolution.
