A projector (110) that maintains energy reduction while adjusting and controlling lamp power and projects an OSD screen with high visibility is provided. The projector (110) includes a light source output adjustment unit (304) that controls output of a light source (221) according to brightness of a video signal, and a superimposed image projection unit (301, 300) that superimposes a predetermined superimposed image on a projection image generated according to the video signal. The superimposed image projection unit (301, 300) generates multiple images with identical content but at least partially different brightness and projects a different superimposed image depending on the projection image. |
