Abstract
A device and method is provided for projecting an image within a defined content area using a plurality of projectors configured to each project a portion of an image. The device comprises a defined content area into which the image is projected by the plurality of projectors. A first group of projectors can be selected from the plurality of projectors and set at a first zoom level, then aligned and superpositioned with respect to one another to increase the pixel resolution and brightness of the projected image. The projectors can project a majority of projector light within the content area. A second group of projectors can be selected from the plurality of projectors, set at a second zoom level, aligned and superpositioned adjacent each other to project a majority of projector light within the content area. The first group of projectors can be superimposed with the second group of projectors to fill the content area and increase the pixel resolution and brightness of the projected image.
