US 9,071,773 B2 · Projection system

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.

Dependent claims

A projection apparatus, comprising:

a processor coupled to a memory;
a combining unit that generates a first combined image which includes a first image and a second image different from the first image;
a communicator configured to transmit the second image to another projection apparatus, wherein the another projection apparatus is configured to project a second combined image including the second image;
a controller configured to control the communicator to transmit, to the another projection apparatus, information relating to a position where the second image is combined with the first image;
and
a projector configured to project the first combined image in a mode in which the first combined image and the second combined image are projected to be combined with each other on a screen,
wherein the combining unit is implemented by the processor.
