Provided is a video image converter that generates attitude data of a projector based on motion data in projecting moving picture data, stores the attitude data in a storage unit, corrects the moving picture data based on the attitude data, and stores the corrected moving picture data in the storage unit. The projector plays back the corrected moving picture data stored in the storage unit and projects the corrected moving picture data onto a projection plane. A cradle supports the projector and changes an attitude of the projector based on the attitude data stored in the storage unit.
