Abstract
A projection apparatus includes a communication unit, an obtaining unit, a projection unit, a generator, and a controller. The communication unit communicates with an other projection apparatus. The obtaining unit obtains image data and the projection unit projects an image based on the image data obtained by the obtaining unit. The generator generates an on-screen-display (OSD) image. The controller controls the projection unit to project a projection image by superimposing the OSD image onto an image, based on the image data obtained by the obtaining unit, in a stack projection mode in which a projection image of the projection unit and a projection image of the other projection apparatus are projected to be superimposed with each other, and to transmit, to the other projection apparatus, information concerning a position at which the OSD image is superimposed.
