Field-sequential color projectors have the advantage of high resolution, but they cause color breakup. It is supposed that this phenomenon is observation of clear color by the divided color image, which occur by rapid eye movements, even if the frame frequency is beyond the critical fusion frequency(CFF). To explain the mechanism of the color breakup, we made an apparatus that can present the divided image of each color fieLtd.o the retina by a moving edge with high retinal velocity, in condition without eye movement. If the discrimination of the color depends on the divided color width, the frame frequency is linear to retinal velocity. The threshold frequency, however, saturated when the retinal velocity was 100 to 200 deg/s, and then it increased again. Moreover, the appearance of the divided color image changed from clear colors to pale colors. These results suggest that there are complex mechanisms of the occurrence of the color breakup.
