The apparatus includes a 3D object reconstruction unit for extracting, from images captured from at least two areas located at different distances, information about a 3D object and information about cameras, and then reconstructing the 3D object. A resolution calculation unit measures size of a space area, covered by one pixel of each of the images in a photorealistic image of the 3D object, and then calculates resolutions of the images. A texture generation unit generates textures for respective levels corresponding to classified images by using the images classified according to resolution level. A rendering unit selects a texture for a relevant level depending on a size of the 3D object on a screen, and then renders the selected texture.
