A naked eye 3D display device is provided. The naked eye 3D display device includes a directional projection screen, a laser light source, a red monochromatic laser light source, a green monochromatic laser light source and a blue monochromatic laser light source. Lights emitted by the three monochromatic laser light sources emit incident light on the directional projection screen with nano-grating pixels at specific angles and specific positions, and the same emergent light fields are formed. The laser light source provides multi-perspective image pixels. The multi-perspective image pixels match a nano-grating pixel array on the directional projection screen. By a direct spatial modulation for the laser projection light, colorful 3D display is achieved. There is no crosstalk between various viewpoints. The naked eye 3D display device has no visual fatigue and has a low cost.

A system and method for creating a 3D virtual model of an event, such as a wedding or sporting event, and for sharing the event with one or more virtual attendees. Virtual attendees connect to the experience platform to view the 3d virtual model of the event on virtual reality glasses, i.e. a head mounted display, from a virtual gallery, preferably from a user selected location and orientation or a common location and orientation for all virtual attendees. In one form the virtual attendees can see and interact with other virtual attendees in the virtual gallery.

A sphere-on-sphere chassis system is disclosed. The sphere-on-sphere chassis system may include a first hollow sphere having a first diameter and a second hollow sphere positioned inside of the first sphere to form a channel therebetween. The second hollow sphere may have a second diameter. The second diameter is less than the first diameter. The sphere-on-sphere chassis system may further include a liquid filling at least a portion of the channel. The liquid may be a clear, highly conductive solution. Alternatively, the channel may be filled by a gas or a vacuum may be created within the channel. Each of the first hollow sphere and the second hollow sphere includes a component layer with a unique series of pockets for housing electromagnets, and may also house wireless energy transmission devices such as resonant inductive chargers and resonant inductive receivers. The spherical device is understood to be designed so that electromagnets may be configured to emit positive and negative electromagnetic waves inwardly and outwardly with respect to the center of each sphere to create relative movement between the inner sphere and the outer sphere.

A stereo image generating method and an electronic apparatus utilizing the method are provided. The electronic apparatus includes a first camera and a second camera capable of capturing stereo images, and a resolution of the first camera is larger than that of the second camera. In the method, a first image is captured by the first camera, and a second image is captured by the second camera. The second image is upscaled to the resolution of the first camera, and a depth map is generated with use of the first image and the upscaled second image. With reference to the depth map, the first image is re-projected to reconstruct a reference image of the second image. An occlusion region in the reference image is detected and compensated by using the upscaled second image. A stereo image including the first image and the compensated reference image is generated.

A system for acquiring a sequence of image frames for display having depth perception through motion parallax includes a base unit, a stage unit, and a camera unit. The stage unit is disposed over the base unit and is configured to rotate, with respect to the base unit, about an axis of rotation, and is configured to hold the camera element thereon at a predetermined offset, as measured from the axis of rotation to a no-parallax point or least-parallax point of the camera element. The camera element is configured to acquire a sequence of image frames, as it is rotated about the axis of rotation by the stage unit and is kept at the predetermined offset, and is configured to acquire the sequence of image frames during the rotation. The predetermined offset is a positive distance value.

In on the general aspect, a camera rig can include a first tier of images sensors including a first plurality of image sensors where the first plurality of image sensors are arranged in a circular shape and oriented such that a field of view of each of the first plurality of image sensors has an axis perpendicular to a tangent of the circular shape. The camera rig can include a second tier of image sensors including a second plurality of image sensors where the second plurality of image sensors are oriented such that a field of view of each of the second plurality of image sensors has an axis non-parallel to the field of view of each of the first plurality of image sensors.

A method is provided for generating an autostereoscopic display. The method includes acquiring a first parallax image and at least one other parallax image. At least a portion of the first parallax image may be aligned with a corresponding portion of the at least one other parallax image. Alternating views of the first parallax image and the at least one other parallax image may be displayed.

A video display system includes a source device for reproducing and outputting contents; and a display device for displaying contents which is output from the source device. Upon receiving a message for requesting display of a 3D video from the source device in a state of unreadiness to display the 3D video, the display device transmits a message for stopping reproduction of 3D contents to the source device. Upon receiving the message for stopping reproduction of 3D contents, the source device stops reproduction of the 3D contents. Upon completing preparations for displaying the 3D video, the display device transmits a message for reproducing the 3D contents to the source device. Upon receiving the message for reproducing the 3D contents, the source device reproduces and outputs the 3D contents.

A computer system that provides stereoscopic images is described. During operation, the computer system generates the stereoscopic images at a location corresponding to a viewing plane based on data having a discrete spatial resolution, where the stereoscopic images include image parallax. Then, the computer system scales objects depicted in the stereoscopic images so that depth acuity associated with the image parallax is increased, where the scaling is based on the spatial resolution and a viewing geometry associated with a display. For example, the viewing geometry may include a distance from an individual that views the stereoscopic images on the display and the display. Alternatively, the viewing geometry may include a focal point of the individual. Next, the computer system provides the resulting stereoscopic images to the display. In this way, the computer system may optimize the depth acuity for data having discrete sampling.
