A control unit (31) controls three light sources (21a to 21c) so that, among three individual images (5a to 5c), projection of an image (5b) to be projected second is started at a time point (t4) later than a time point (t3) at which a period of 250/3 milliseconds has elapsed from a projection start time point (t1) for an image (5a) to be projected first. Consequently, the visual effect of sequential projection of individual images is more easily achieved than when the projection of the second individual image (5b) is started at the time (t3).
