Reflectance properties play an important roll in generating realistic images and a lot of research has been done to determine the reflectance of real objects from images[Sato et al. 1997]. In the process of the estimation, the Lambertian model is commonly used to estimate the diffuse reflection of real objects. However, this model could not represent the diffuse reflection properly[Oren and Nayar 1994]. In this paper, we propose a new diffuse reflection model which can represent the diffuse reflection of real objects. Our proposed model is very simple and can be used for estimating reflectance of real objects.
