Abstract
Measurement of camera response function (CRF) has become an important technique in the field of computer graphics and radiance measurement. It can be used to achieve accurate modeling and high dynamic range imaging. A method was developed in this paper by using a polariscope to provide accurate radiance for direct measurement of the CRF. The experimental results show that the accuracy of the estimated CRF obtained by the new approach is about 5% better than that of the previous method.
