Abstract
A display apparatus includes an image projector and a controller. The image projector emits image projection light that projects an image onto a projection-target surface. The controller controls, in a time division manner, the emission direction of the image projection light emitted by the image projector. The controller performs control to prevent the sum of the area of one or more regions of the projection-target surface, on which the image projection light is projected, from exceeding a predetermined upper limit.
