ABSTRACT:
Apparatus and method which map a texture image onto a polygonal area in which the mapped image can have a dynamic brightness range greater than the dynamic brightness range of the original texture image. The brightness levels of the pixels of the texture image are ascertained and reduced, and the polygonal area onto which the texture image is mapped is shaded by multiplying the reduced brightness levels of the pixels by a shading factor, wherein a shading factor greater than 1 produces a mapped texture image which has a dynamic brightness range that is greater than the dynamic brightness range of the texture image.
