IMAGE PROJECTION APPARATUS TILING SYSTEM AND METHOD

摘要

In one tiling system described below, a first portable projection device (101) projects a first image (103) on a projection surface (105). A periphery delimiting light source projects a peripheral image demarcation (107), which can be non-visible light, about the first image (103). A second portable projection device (102) projects a second image (104) on the projection surface (105) with a second peripheral image demarcation (106). The first peripheral image demarcation (107) and the second peripheral image demarcation (106) can be uniquely encoded. A control circuit (229) that is operable with the one or more light sources and a light modulator is configured to tile images by altering its image as a function of the peripheral image demarcations.
