A projector includes: an image projection unit which modulates light emitted from a light source and projects the modulated light; a cooling fan which cools the image projection unit; a light source control unit which controls lighting of the light source; a cooling control unit which controls operation of the cooling fan; an input operation unit which receives input operation; and a control unit which allows the light source control unit to decrease the luminance of the light source or allows the cooling control unit to increase the rotational speed of the cooling fan during the period from the time when the input operation unit receives the first ending operation to the time when the input operation unit receives the second ending operation.
