Abstract (in Japanese) (See Japanese page) 
(in English) Recently, pre-captured AR systems have been proposed as a novel type of mobile AR. In the pre–captured AR, omnidirectional images are captured at a number of fixed points and virtual objects are rendered with high quality in an offline process. In the online process, the system shows user perspective images generated from omnidirectional AR images based on the estimated pose of the mobile device. However, one problem of naive pre-captured AR system is the reduction of the reality in an AR experience due to the difference in illumination environments between the pre-captured image and the real world. In this paper, we propose a novel pre-captured AR system considering the change of real-world illumination. First，omnidirectional images are preliminarily captured under various illumination environments. In the online-stage，one of pre-captured images that is similar to the real-world illumination of the real scene captured in real-time, is selected and is displayed to the user.
