To solve the problem that intended visual effects are difficult to obtain although individual images are sequentially projected, since a road surface area allowed for projection of a certain image is limited, and also because a split number of the image is restricted.SOLUTION: A control unit 31 controls three light sources 21a-21c so as to start the projection of an image 5b to be projected secondly at a time point t4, subsequent to a time point t3 after the lapse of a period of 250/3 milliseconds from a projection start time point t1 of an image 5a to be projected first among three individual images 5a-5c. Consequently, visual effects due to projection of sequential individual images are easier to obtain compared to when starting the projection of the second individual image 5b at the time t3.SELECTED DRAWING: Figure 7
【課題】ある像の投影のために許容される路面面積が限られ、その像の分割数にも制約があり、シーケンシャルに個別像を投影しても意図した視覚効果が得られにくい。【解決手段】制御部31は、3個の個別像5a~5cにおいて1番目に投影される像5aの投影開始時点t1から250/3ミリ秒の期間が経過した時点t3よりも後の時点t4で2番目に投影される像5bの投影が開始されるように3個の光源21a~21cを制御する。これにより時刻t3で2番目の個別像5bの投影を開始する場合よりもシーケンシャルな個別像の投影による視覚効果が得られやすくなる。【選択図】図7
