Abstract: An image generation apparatus generates an image whose background region on which a virtual object appearing in the real space is not superimposed is drawn in a background color having a predetermined luminance so as to make a region of a shadow of the virtual object look relatively dark. A rendering section renders the shadow of the virtual object appearing in a mesh structure in the real space by rendering not only the virtual object but also the mesh structure in the real space. A pixel value conversion section heightens colors of all pixels such that the background region uniformly takes on a background color having a predetermined luminance. A shadow/background processing section identifies the region of the shadow of the virtual object, sets the background region other than the shadow to the background color, and sets the shadow region to a color whose luminance is equal to or lower than that of the background color.
