Abstract
Disclosed is a visual communication signal (32) which comprises image model information (10) for generating 3-D images. The image model information (10) may comprise a 3-D image model, e.g. a 3-D wireframe model or a 3-D voxel map. Some of the generated 3-D images may have a relatively low image quality. The visual communication signal (32) further comprises image enhancement information (20) corresponding to at least part of the 3-D images for enhancing the image quality of the generated 3-D images. This image enhancement information (20) may comprise image information corresponding to one or more single viewpoints (22, 24) and/or image information corresponding to one or more ranges of viewpoints (26, 28). The visual communication signal (32) may be transmitted from a transmitter (30) to a receiver (34) in a visual communication system (40) such as a 3-D television system or a 3-D teleconferencing system. Alternatively, the visual communication signal (32) may be carried by a tangible medium, e.g. a CD-ROM or a DVD-ROM.
