Photorealistic CG Technology Reconstructing Realistic Images from Analytical Data
When reconstructing images, such as relighting or other user-specific adjustments based on the three extracted data components, the most important factor is image quality. Canon is now working on photorealistic CG technology with high-precision rendering capabilities to reconstruct photo images comparable in image quality to actual photographs, with none of the artificial appearances commonly associated with manipulated images.
One of the keys to developing photorealistic CG technology is the use of spectral color information. While conventional CG renders the visible light range in RGB (red, green and blue), the three primary colors of light, Canon's new technology enhances the precision of color reproduction by dispersing light rays in the visible region to render dozens of fundamental colors. This enables the faithful reproduction of the textures of real-world objects, the seamless synthesizing of actual photo images with CG, and the reproduction of an object as viewed within desired light-source settings.
Another key is the pursuit of high resolution. CG images are composed of triangular shapes called polygons. The more polygons there are in an image, the higher its resolution. Canon is developing a dispersion processing technology capable of handling one billion polygons, more than 100 times the number of polygons contained in an average motion picture.
The third key is high-speed processing. Speed is vital for processing the vast amounts of data required to achieve necessary color performance and high definition. Canon is conducting research into high-speed processing that is at least 100 times faster than conventional image-processing.
Canon's photorealistic CG technology is also effective in synthesizing photographic and CG images, enabling the smooth synthesis of photographic and CG images automatically, doing away with the troublesome process of manually manipulating each frame in order to achieve realistic results. The technology has the potential to easily create revolutionary composite images for major motion pictures, advertisements and other projects.
