The apparatus includes an image projecting means to project pairs of images associated with different cross-sectional planes of the three-dimensional image; at least one optical display arrangement including a plurality of optical elements, wherein each of the plurality of optical elements is operable to be switched between a first optical state and a second optical state; a control arrangement that is operable to control the at least one optical display arrangement to separately switch each optical element from the first optical state to the second optical state, and the image projecting means to project a separate pair of images on each optical element in the second optical state; and at least one optical device that allows display of the three-dimensional image to each eye of the user.

A digital loupe system is provided which can include a number of features. In one embodiment, the digital loupe system can include a stereo camera pair and a distance sensor. The system can further include a processor configured to perform a transformation to image signals from the stereo camera pair based on a distance measurement from the distance sensor and from camera calibration information. In some examples, the system can use the depth information and the calibration information to correct for parallax between the cameras to provide a multi-channel image. Ergonomic head mounting systems are also provided. In some implementations, the head mounting systems can be configurable to support the weight of a digital loupe system, including placing one or two oculars in a line of sight with an eye of a user, while improving overall ergonomics, including peripheral vision, comfort, stability, and adjustability. Methods of use are also provided.

A stereo viewing device comprises a first lens comprising a first lens filter, and a second lens comprising a second lens filter. The first lens filter comprises a first set of light absorbing dyes that define a first set of rejection bands. The first set of light absorbing dyes comprises at least a first polymethine dye. The second lens filter comprises a second set of light absorbing dyes that define a second set of rejection bands different from the first set of rejection bands. The second set of light absorbing dyes comprises at least a second polymethine dye.

A system that incorporates teachings of the present disclosure may include, for example, a media processor having a controller to record stereoscopic media content supplied by a multimedia system, receive from a communication device a request for the recorded stereoscopic media content, determine rendering capabilities of the communication device, generate transcoded content by transcoding the recorded stereoscopic media content according to the rendering capabilities of the communication device, and transmit to the communication device the transcoded content. Other embodiments are disclosed and contemplated.

An infrared polarizing filter is attached to an infrared synchronization signal radiator of a stereoscopic image display device which alternately displays right and left images by time-division with polarized light in one direction to radiate the polarized-light infrared synchronization signal. The problem with the occurrence of crosstalk is solved. Stereoscopic image appreciation eyeglasses have polarizing plates, visual field opening/closing liquid crystal cells and tilt correcting liquid crystal cells The synchronization signal is received by a receiver mounted on an eyeglass frame. The tilt correcting liquid crystal cells are adjusted based on the eyeglass frame tilt angle detected.

To apply an edge effect to a 3D virtual object, a display system receives user input indicative of a desired display region of a 3D virtual object, defines a bounding volume corresponding to the desired display region, and clips the edges of the 3D virtual object to the surfaces of the bounding volume. The display system applies a visual edge effect to one or more of the clipped edges of the 3D virtual object, and displays to the user of the 3D virtual object with the visual edge effect. The technique can include selectively discarding pixels along a surface of the bounding volume, based on a depth map indicative of height values of the 3D virtual object at different horizontal pixel coordinates where the visual edge effect is applied only for edge pixels not discarded.

Eyeglasses have at least one partially transparent screen as an eyeglass lens and multiple optical recording apparatuses for recording images in a field of vision of a user of the eyeglasses. The recorded images can be processed further by a processing apparatus, in such a manner that a position of the eyeglasses relative to a patient can be determined, and, based on this position, a position of a planned implant in the jaw of a patient can be represented on the at least one partially transparent screen in the form of a marking.

According to one of aspects, a display device includes: a display unit configured to three-dimensionally display an object by displaying images respectively corresponding to both eyes of a user by being worn; a detection unit configured to detect a real body that operates the object; and a control unit configured to change the object according to movement of the real body, and perform order processing for ordering a product corresponding to the object.

Embodiments allow different viewers of a shared display to see different images. Images may have different combinations of polarization and time slices that correspond to filters in glasses worn by the viewers. 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 be presented to left and right eyes for 3D stereoscopic viewing. The lenses of the glasses may have a filter that selects light of a specific polarization combined with a shutter that passes images during a specific time slice. The polarization filter may select circularly polarized images of a desired orientation and emit linearly polarized images. The shutter may use liquid crystals to twist the linearly polarized images during the desired time slice so that a final linear polarizer passes the image to the viewer.
