Abstract: A method of calibrating a projection system is disclosed. The method includes determining a location of at least one hotspot on a screen within the projection system, initiating a calibration sequence of the projection system and ignoring the at least one hotspot during the calibration sequence of the projection system.

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.

Abstract: A method of correcting luminance non-uniformity in a tiled projection system is disclosed. The method includes projecting with a plurality of projection devices a composite image wherein the composite image comprises a plurality of tiled images on a display surface with an overall luminance and correcting a luminance non-uniformity of the plurality of tiled images, wherein the luminance non-uniformity is based on a dimmed at least one of the plurality of tiled images, wherein correcting the luminance non-uniformity comprises utilizing at least one of the plurality of projection devices to adjust the overall luminance of the plurality of tiled images on the display surface.

Abstract: An optical component of a projector is driven with a signal that contains one or more components that act to substantially cancel one or more unwanted oscillatory displacements of the optical component resulting from one or more unwanted oscillatory forces.

Abstract: A display system having a number of individual display devices that cooperate to display a large-scale image includes a number of display devices configured to cooperate to produce the large-scale image by each displaying a portion of the large-scale image; at least one camera for imaging the large-scale image displayed by the display devices and an image server receiving output from the camera. The image server is configured to determine whether any mullions exist in the large-scale image using the output from the camera and to modify image signals for the display devices to eliminate any mullions.

Abstract: The ratio of a refresh rate of a display device to a refresh rate of source video is determined. The display device is to display the source video over a repeating number of sub-frames, in sub-frame order. The sequence of frames of the source video is determined for the display device that maintains the ratio. The sequence of frames is delineated so that each frame is represented by the number of sub-frames over which the display device displays the source video. The sequence of frames as delineated by the sub-frames is adjusted to ensure as much as possible that each frame is represented by the same number of sub-frames within the sequence. The source video is displayed on the display device using the sequence of frames as delineated and as adjusted.
