Moving images of a space, which includes objectsandof a display target, as viewed from reference points are created in advance as reference images, and they are combined in response to actual positions of the points of view to draw a moving image. When the objectis displaced as indicated by an arrow mark in the space, reference points of viewtoare fixed as depicted in (a). Alternatively, the reference points of view are displaced in response to the displacement like reference points of viewtoin (b). Then, the moving images from the reference points of view are generated as the reference images.

Reference image generation apparatus, display image generation apparatus, reference image generation method, and display image generation method

With respect to a space including an objectof a display target, images of the space viewed from reference pointstoof view are created as reference images, andin advance and they are synthesized according to a position of an actual point of view to render a display image. In the certain reference image, data other than a partrepresented only in it is deleted. At the time of rendering of the deleted part, the other reference imagesandare used.

Freely selected point of view image generating apparatus, reference image data generating apparatus, freely selected point of view image generating method, and reference image data generating method

For a space including an object to be displayed, images of the space viewed from reference points of view are created in advance as reference images, and the reference images are combined according to a position of an actual point of view to draw a display image. In this case, a reference image not displaying reflection is used to determine the color of the object (S). In a case of expressing reflection of another object (Y in S), a position of the reflected object is estimated in a three-dimensional space (S), a position on the reference image corresponding to the position is acquired (S), and a color of the position is combined with the color of the object (S).

Image generation apparatus and image generation method

To achieve a balance between responsiveness of image display with respect to movement of a viewing point, and image quality. Reference viewing points are set in respect of a space containing an object to be displayed, and images of the space as viewed from these respective reference viewing points are created as reference images. Meanwhile, when pixel values of display images from a virtual camera are determined, reference images are selected wherein a point on the object represented by the pixel in question is represented as an image, and the values of these pixels are combined using a rule based on the positional relationship etc. of the reference viewing points with the virtual camera.
