In order to project a certain image, the allowable road surface area is limited, the number of divisions of the image is limited, and a desired visual effect is difficult to obtain even if individual images are projected in sequence. The control unit (31) controls the three light sources (21a-21c) such that projection of the second projected image (5b) is started at a time point (t4) after a time point (t3) at which a period of 250/3 milliseconds has elapsed from a projection start time point (t1) of the first projected image (5a) among the three individual images (5a-5c). Therefore, compared with the situation that the projection of the second individual image (5b) is started at the time (t3), the visual effect based on the projection of the individual images in sequence is easier to obtain.

    为了投影某个像而允许的路面面积有限,该像的分割数也存在制约,即使按顺序投影单独像也难以得到所希望的视觉效果。控制部(31)控制三个光源(21a~21c),使得在比从三个单独像(5a~5c)中第一个被投影的像(5a)的投影开始时间点(t1)起经过了250/3毫秒的期间的时间点(t3)靠后的时间点(t4)开始第二个被投影的像(5b)的投影。由此,与在时刻(t3)开始第二个单独像(5b)的投影的情况相比,容易得到基于顺序的单独像的投影的视觉效果。
