摘要:
A display system for a providing a three-dimensional effect with controlled reflections is disclosed. In one embodiment, the display system includes a display; and a beam splitter positioned between the display and the viewing location. The beam splitter transmits or reflects light based on a characteristic of the light. A physical prop is positioned between the beam splitter and the viewing location. The display is oriented to emit light toward the beam splitter and displays an image at least partially viewable in the viewing location through the beam splitter, such that the image is substantially un-attenuated by the bean splitter. Light reflected from the physical prop and further reflected by the beam splitter toward the viewing location is at least partially viewable in the viewing location. The display system is suitable to enable a substantially full brightness of the image to be viewable in the viewing location.

A system for sensing and controlling eye contact for a robot. The system includes a robotic figure with a movable eye. The system includes a light source positioned in the robotic figure to output light through a light outlet of the eye. A light sensor is included that senses light striking surfaces in a physical space in which the robotic figure is positioned including the output light from the light source. The system includes an image processor processing output of the light sensor to identify a location of a target formed by the output light striking surfaces in the physical space and to identify a location of a face of a human. Further, the system includes a robot controller generating eye movement control signals based on the location of the target and the location of the face to position the eye to provide eye contact with the human observer.

Display systems for achieving collimated projection effects. For example, in a theatrical or concert installation, display systems can be used to project images of scenery that appear to be vast and at a great distant behind the viewing window. The system may include a flat panel display, a corrective mirror, and a concave mirror positioned for viewing by an observer. The corrective mirror pre-warps an image generated by the flat panel display and reflects the undistorted image onto the concave mirror such that the observer perceives the image generated by the flat panel display as being at a large distance. The corrective mirror does not distort with changes in viewpoint. In another implementation, the system may include a short throw projector generating an image, a free-form projection screen, and a concave mirror positioned for viewing by many observers through a viewing window.

An apparatus for displaying three dimensional (3D) images to a viewer without the need for 3D glasses. The apparatus includes a first display device horizontally oriented and operable to alternately display a first parallax and a second parallax barrier. The first parallax barrier corresponds with a first viewer location and the second parallax barrier corresponds with a second viewer location. The apparatus includes a second display device positioned parallel to the first display device and operable to alternately display first 3D content corresponding with the first viewer location and second 3D content corresponding with the second viewer location. The apparatus includes a directional backlight assembly alternately backlighting the second display device with first light directed toward the first viewer location and second light directed toward the second viewer location. The apparatus includes a controller synchronizing time multiplexed operations of the first and second display devices and the directional backlight assembly.

A special effects device for providing an energy sword effect. The device includes two long plastic semi-cylinders, and these two blade body members are rolled perpendicular to their length, which creates compact cylinders of material of small volume that can be provided on a pair of spools in a hilt. To extend the blade, a motor provided in the hilt unrolls the blade body members from the spools. Each blade body member passes through a blade forming guideway that nests the semi-cylindrical blade body members together as they leave the hilt. To retract the blade, the process is reversed. The lighting of the blade is achieved with a flexible strip of light sources. The light source strip is attached to a blade end cap and positioned in the center of the two blade body members such that it is pulled up along with the blade body members during their extension.

A multi-theater light source for two or more 3D projectors positioned in differing spaces. The apparatus includes a first light source outputting light to display left eye content, and the apparatus includes a second light source outputting light for use by the projectors to display right eye content. The apparatus includes a switching device that receives the light output from the first and second light sources and switches between first and second operating states to route the left and right eye light. In the first operating state, the switching device directs the light from the first light source toward a first projector and the light output from the second light source toward a second projector. In the second operating state, the switching device directs the light output from the first light source toward the second projector and the light output from the second light source toward the first projectors.

A three dimensional (3D) display apparatus for without 3D glasses. The display apparatus includes a display element operated to display left and right eye images. A back light assembly back lights the display element and includes light bars with a row of infrared (IR) light receivers that are each paired to a white light emitting diode (LED). Viewers in seats in tiered rows such that their heads are in known viewing locations. Left and right side illuminators illuminate the left and right sides of the faces of the viewers with IR light. The IR light is synchronized with display of the left and right eye images. IR reflected from viewers' faces pass through the display element and is focused onto IR light receivers, which causes LEDs to emit light onto the display element and provide left or right eye images to the viewers at their left or right eyes.

An illumination distribution system for distributing high power illumination to a set of projectors. The system includes a display element, such as a spatial light modulator (SLM), receiving light from a laser. The system includes a fiber optic array with connection locations for optical fibers. The system includes projectors that are each coupled to the fiber optic array at one or more of the connection locations with at least one optical fiber. The system includes a controller operating the display element at a first time to display a first hologram and at a second time to display a second hologram differing from the first hologram such that the laser light is split, with equal or unequal splitting ratios, into beams that are selectively directed to the connection locations of the fiber optic array (e.g., based on a 2D routing pattern used to generate the holograms).

A 3D display apparatus for providing a Pepper's Ghost effect. The apparatus includes a background set spaced apart from a viewing space such that a viewer in the viewing space has a line of sight to the background set. The apparatus also includes a mirrored surfaces fan, which includes a motor, a hub rotatable by the motor, and a plurality of fan blades attached in a spaced apart manner to the hub to rotate with the hub. In some cases, each of the fan blades has a reflective region on a side facing away from the background set. The apparatus also includes a display device with a screen displaying an image of an object. The screen is positioned at an offset angle in the range of 40 to 60 degrees from a rotation plane for the sides of the fan blades. Often, the display device includes a 3D autostereoscopic device.
摘要:
A special effects (FX) system for generating a penumbra or glow effect about an object. Briefly, the FX system includes at least one sheet of retroreflective material and a penumbra activator. The penumbra activator is designed to selectively direct light toward a reflective surface of the retroreflective material. For example, the penumbra activator may include an elongated core element extending from a hilt. The body of the core element may include strings or sets of direction light sources, which may be spaced apart along the length of external surfaces of the core element body. A controller is used to operate the light sources such as by sequentially illuminating the lights sources from an end near the base/hilt to an end near a tip/distal end of the core element body, with earlier lit sources remaining on in some cases to cause a light sword blade to grow out of the hilt.
