Abstract: An imaging system (300) configured to reduce perceived flicker in three-dimensional images is provided. The imaging system (300) can include a plurality of light sources (305,306,307), a light combiner (302), a light modulator (303) and a polarization rotator (301). The light combiner (302) combines light received from each of the light sources into a combined beam (304). A first light portion (313) in the combined beam has a first light portion polarization state that is different from a second light portion polarization state of a second light portion (314). The light modulator (303) produces images by modulating the combined beam (304) along a projection surface (316). The polarization rotator (301) selectively rotates a polarization state of the combined beam (304) in synchrony with an image refresh cycle of the imaging system. A circular polarizer (1004) can be used to transform linear polarization states to circular polarization states.

Abstract: Briefly, in accordance with one or more embodiments, an image or projection cone is projected onto a projection surface via a raster scan to generate the image, or in a light cone. Movements of two or more input sources with respect to projection cone are detected, and a determination is made whether the input sources have crossed a crossover line in the projection cone. If the input sources have moved greater than a threshold amount after crossing the crossover line, position data between the input sources may be exchanged to reflect proper position data for the input sources.

Abstract: An image projection system (103) includes an image projector (104) and an image orientation device (106). The image orientation device (106) can be configured to cause a reference line (110) associated with an image (108) to remain aligned in a predetermined orientation on a projection surface (109) regardless of projection system motion. A second image orientation device (206) can be included as well. The second image orientation device (206) can be configured to cause portions of an image (208) to move with projection system motion while a reference line (210) remains stable.

Abstract: A projection apparatus memorizes settings as a function of location, orientation, elevation, or any combination. The projection apparatus recalls the settings when the location, orientation, elevation, or combination of the projection apparatus matches memorized values. Memorized settings may include projector settings, image source settings, audio output settings, audio source settings, and the like.

Abstract: 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.

Abstract: A spatially aware apparatus includes a projector. Projected display contents can change based on the position, motion, or orientation of the apparatus. The apparatus may include gyroscope(s), accelerometer(s), global positioning system (GPS) receiver(s), radio receiver(s), or any other devices or interfaces that detect, or provide information relating to, motion, orientation, or position of the apparatus.
