Abstract (in Japanese) (See Japanese page) 
(in English) The development of visual expressions using optical illusions in CG utilize is progressing. However, there are many illusions whose perceptual characteristics have not yet been clarified. In particular, the frame rate of general-purpose displays is usually 60fps, and the frame rate dependence of the illusion has not been sufficiently investigated. In this study, we investigated the frame-rate dependence of the color and shape illusions of the Benham's Top and the rubber pencil illusion, respectively, by presenting images at different frame rates from 10 fps to 240 fps to subjects. The results showed that the perception started around 30 fps and improved up to around 120 fps for both illusions. It is expected that this method will be used in the future to examine the frame rate that can sufficiently express the reality of the illusion in CG images.
