<P>PROBLEM TO BE SOLVED: To draw the outline of an object disposed in a virtual space showing a game world. <P>SOLUTION: In a game device 201, a generating unit 202 generates a first image indicating how plural objects disposed in a virtual space showing a game world appear from a viewpoint set in the virtual space in a line-of-sight direction set in the virtual space, and a second image each having a depth value indicating a depth to the viewpoint at a position drawn at each pixel position in the first image in the plural objects, as a pixel value at the pixel position. An extracting unit 203 obtains a third image by applying an outline extraction filter to the second image. A drawing unit 204 obtains a fourth image by drawing an outline indicated by the third image with the first image used as a background. <P>COPYRIGHT: (C)2013,JPO&INPIT |
