ABSTRACT:
A projector which projects an image on a projection plane includes a projection mechanism having a first projection mode in which the image is projected on the projection plane by giving priority to color reproducibility and a second projection mode in which the image is projected on the projection plane by giving priority to brightness. The projector also includes a central processing unit. The central processing unit has a determination unit which determines a type of the image, a selection unit which selects one of the first projection mode and the second projection mode based on a determination result of the determination unit, and a control unit which controls the projection mechanism in accordance with one of the first projection mode and the second projection mode selected by the selection unit.
