Abstract(in Japanese) (See Japanese page)
Abstract(in English) It is known that color perception tends to be roughly constant despite the changing illumination. This phenomenon is called the "color constancy". In the past, the mechanism of color constancy has been studied in a variety of research fields including psychophysics and computational approaches. However, these research fields disregarded the dynamic process of color constancy in the visual system. This study proposes a computational model of color constancy which takes into account the dynamic process in the visual system. In addition, the validity of the proposed model is verified by a visual search task which is an effective experimental method to examine the dynamic process in the visual system. This model is constructed under the assumption that the detection mechanism of space-varying illumination necessary for approving color constancy exists during the pre-attentive process. Using the proposed model it is possible to explain the experimental results with space-varying illumination.
