| Abstract(in English) | We propose a method for synthesizing an image in a virtual-lighting condition by the Image-Based Rendering. It is known that the images with any light directions can be synthesized by a linear combination of three images which are taken with different light source directions, if a Lambertian reflection model is assumed as well as a single point light source at the infinity. However, the previous method can not cover nonlinear elements, such as specular reflection, shadows, etc. In our method, these nonlinear elements are transformed to be linear, and realistic images can be synthesized under a virtual lighting condition by a linear combination of three images. |
