VISIBLE LIGHT PROJECTION DEVICE

摘要

This visible light projection device is provided with: a detection unit for detecting a first region that emits invisible light; a projection unit for projecting onto a second region including the detected first region using visible light; and a control unit that causes the projection unit to perform projection on the basis of colors selected by an operator. When a first color is selected as the color of visible light to be projected by the projection unit onto the region other than the first region in the second region, the control unit informs the operator of first options in such a way as to allow the operator to select therefrom the color of visible light to be projected onto the first region by the projection unit. When a second color, which is different from the first color, is selected as the color of visible light to be projected by the projection unit onto the region other than the first region in the second region, the control unit informs the operator of second options, which are a combination of candidates different from those included in the first options, in such a way to allow the operator to select therefrom the color of visible light to be projected onto the first region by the projection unit.
