A display device according to one aspect of the present invention includes: a display unit that displays an image including a plurality of viewpoint images; and a separator that includes a plurality of first electrodes that form, at a first pitch, a plurality of first unit separators that separate the plurality of viewpoint images, a plurality of second electrodes that form a plurality of second unit separators at a second pitch which is different from the first pitch, and a liquid crystal layer. The plurality of first electrodes and the plurality of second electrodes are opposed to each other with the liquid crystal layer interposed therebetween.

A novel light source for a 3D display system includes a plurality of left eye light emitters and a plurality of right eye light emitters. The left eye emitters include a broad spectral distribution emitter and an overlapping narrow spectral distribution emitter in each of the blue, green, and red color bands. Similarly, the right eye emitters include a broad spectral distribution emitter and an overlapping narrow spectral distribution emitter in each of the blue, green, and red color bands. The combined spectral distributions of each of the broad and narrow emitters provide a primary light for each color and for each eye that has a desirable spectral shape, including wide bandwidth and short tail(s). The invention thus minimizes cross-talk and speckling in left- and right-eye images of 3D display systems.

Embodiments present different images to multiple viewers of a shared display using glasses with lenses that transmit only selected images from the display. The images viewed by each of the glasses may be based on the tracked position and orientation of the glasses, so that the images correspond to the user's viewpoint. Different images may also be presented to left and right eyes for 3D stereoscopic viewing. The position and orientation of the lenses of the glasses may be tracked by analyzing images from one or more cameras observing the glasses. Glasses may have distinctive geometric shapes or features, such as circular lenses or rims, or recognizable blobs or patterns, to facilitate tracking. The lenses of the glasses may combine multiple barriers such as anaglyph filters, polarizing filters, and shutters, to select images from the display. Glasses may also be used as pointing devices to select and manipulate 3D objects.

An electrically controlled spectacle includes a spectacle frame and optoelectronic lenses housed in the frame. The lenses include a left lens and a right lens, each of the optoelectrical lenses having a plurality of states, wherein the state of the left lens is independent of the state of the right lens. The electrically controlled spectacle also includes a control unit housed in the frame, the control unit being adapted to control the state of each of the lenses independently.

Embodiments herein describe a display device for performing wavelength multiplex visualization (WMV). The display device includes a display screen that includes a plurality of pixels where each pixel contains at least two discrete emitters that generate electromagnetic radiation at a certain wavelength. By controlling the luminance of the respective emitter, the display device sets the color of the pixel. When performing WMV, the display device uses the pixels to generate a left eye display frame and a right eye display frame. Generally, the left eye frame is generated using a different set of wavelengths than the right eye frame. The user can wear special glasses that have interference filters in the lenses which permit only one of the wavelengths to pass through. As a result, each eye of the user sees only one of the display frames, thereby creating the 3D effects.

An interface device is provided that is configured to allow viewing of three-dimensional (3-D) content when the interface device is worn. In certain embodiments, a wearable visualization device can be removably coupled to the interface device. The wearable visualization device, when in use, may provide additional viewing functionality, such as facilitating the viewing of augmented reality (AR) or virtual reality (VR).

Various examples of a target for shooting sports with three-dimensional (3D) visual effect are described. In one example, a carrier has a surface on which a background object and a target object are displayed. The background object is depicted in two colors such that, when viewed through a pair of color-coded anaglyph glasses by a user with both eyes, the background object appears to be 3D to the user. The target object is depicted in at least a dark color. In another example, a carrier has a surface on which a background object and a target object are displayed. The target object is depicted in two colors such that, when viewed through a pair of color-coded anaglyph glasses by a user with both eyes, the target object appears to be 3D to the user. The background object is depicted in at least a dark color.

Disclosed herein are dual stereoscopic image display apparatus and method. The dual stereoscopic image display method is performed by a dual stereoscopic image display apparatus, and includes separating a background image including a background and a foreground object image including a foreground object from multi-view stereoscopic image data, setting the background image so that the background image is output via a first display at a first resolution, and setting the foreground object image so that the foreground object image is output via a second display at a second resolution, and synchronizing the background image and the foreground object image into a single stereoscopic image via the first display and the second display, and outputting the stereoscopic image.
