有彩色と白色の照明光間の色変化時における定常順応のための所要時間

抄録

New illuminants, such as LEDs or OELs that can vary their own color, are expected to spread. The opportunities when colored lights are used in lighting are currently increasing. Research on the impression of rooms by the colored light used in the lighting is important knowledge about the adaptation transition at the change of the lighting between chromatic colors. This paper reports the results about the duration necessary for steady adaptation based on the color appearance of the light when the light color changes between chromatic and white. The duration of the necessary adaptation to white light from some chromatic light is shorter than that to chromatic light from white light. The duration of adaptation to chromatic light from white light and that to white light from chromatic light becomes longer with vivid chromatic light.
