A system and method for viewing of two-dimensional (2D) color-encoded images that simulate depth with color include a pair of goggles, the goggles having two lenses that each include a high chromatic dispersive prism disposed adjacent a low chromatic dispersive prism, and a 2D color-encoded image being viewable with the lenses of the goggles which separate colors of the image into different convergence points in the visual field of a user, thereby producing a chromostereoscopic effect.

An augmented reality display system is configured to direct a plurality of parallactically-disparate intra-pupil images into a viewer's eye. The parallactically-disparate intra-pupil images provide different parallax views of a virtual object, and impinge on the pupil from different angles. In the aggregate, the wavefronts of light forming the images approximate a continuous divergent wavefront and provide selectable accommodation cues for the user, depending on the amount of parallax disparity between the intra-pupil images. The amount of parallax disparity is selected using a light source that outputs light for different images from different locations, with spatial differences in the locations of the light output providing differences in the paths that the light takes to the eye, which in turn provide different amounts of parallax disparity. Advantageously, the wavefront divergence, and the accommodation cue provided to the eye of the user, may be varied by appropriate selection of parallax disparity, which may be set by selecting the amount of spatial separation between the locations of light output.

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.

An optical interference coating with reduced back reflectance for 3D glasses based on colour separation has a substantial transmittance at one or more passbands over the visible spectral range in order to view the desired left (right) eye image and a substantial reflectance and absorption at one or more different blocking bands over the visible spectral range in order to block the undesired right (left) eye image while simultaneously reducing the back reflectance of visible light towards the viewer's eye. The thicknesses and materials are chosen such that the left eye reduced back reflectance 3D coated lens transmits the desired left eye image and blocks the right eye image while the right eye reduced back reflectance 3D coated lens transmits the desired right eye image and blocks the left eye image so that a 3D image can be viewed whilst substantially reducing distracting back reflections from the coated lenses.

A wearable apparatus, an anti-peeping display system and an anti-peeping display method are disclosed. The anti-peeping display system includes a display apparatus and a wearable apparatus, the display apparatus is configured to display infrared images, the wearable apparatus acquires the infrared images and converts the infrared images to original images, and the original images are visible images.

A display system suitable for use inside an MRI system bore to display images to a patient undergoing an MRI procedure. The display system includes a curved display structure fitted inside the MRI bore, and having a width and length sufficient to present images to the patient inside the tunnel. First and second EMI shielding layers sandwich the curved display structure. A display electronics module is electrically connected to the curved display structure to provide video drive signals to the curved display structure. A housing for the display electronics module is configured to provide shielding to prevent EM signals from within the housing to affect MRI image processing.

The invention relates to creating and viewing stereo images, for example stereo video images, also called 3D video. At least three camera sources with overlapping fields of view are used to capture a scene so that an area of the scene is covered by at least three cameras. At the viewer, a camera pair is chosen from the multiple cameras to create a stereo camera pair that best matches the location of the eyes of the user if they were located at the place of the camera sources. That is, a camera pair is chosen so that the disparity created by the camera sources resembles the disparity that the user's eyes would have at that location. If the user tilts his head, or the view orientation is otherwise altered, a new pair can be formed, for example by switching the other camera. The viewer device then forms the images of the video frames for the left and right eyes by picking the best sources for each area of each image for realistic stereo disparity.

Using two or more cameras attached to the protective eyewear, three-dimensional views with accurate and natural depth perception of the working area can be displayed for users, so that the user can maintain healthy sitting or standing posture while working on patients or objects located below horizontal eye level. Additional functions including eye protection, zoom-in, zoom-out, on-off, lighting control, overlapping, and teleconference capabilities are also supported using electronic, video and audio devices attached to the eyewear.

A binocular display system comprises: a binocular image pickup system that includes a right eye-use image pickup optical system and a left eye-use image pickup optical system; a binocular display system that includes a right eye-use display unit which displays image information picked up by the right eye-use image pickup optical system, and a left eye-use display unit which displays image information picked up by the left eye-use image pickup optical system; and a correlating means that correlates the binocular image pickup system and the binocular image display system. In addition, a binocular display device comprises an image processing unit that processes the image information obtained by the binocular image pickup system. The image processing unit can enlarge an image and display the same on the binocular display system, and correct the movement of the displayed image when at least a prescribed amount of enlargement is carried out.

Eyewear presenting text corresponding to spoken words (e.g., in speech bubbles) and optionally translating from one language to another. In one example, an interactive augmented reality experience is provided between two users of eyewear devices to allow one user of an eyewear device to share a personal attribute of the user with a second user. The personal attribute can be speech spoken by a remote second user of eyewear converted to text. The converted text can be displayed on a display of eyewear of the first user proximate the viewed second user. The personal attribute may be displayed in a speech bubble proximate the second user, such as proximate the head or mouth of the second user. The language of the spoken speech can be recognized by the second user eyewear, and translated to a language that is understood by the first user. In another example, the spoken words of a remote person is captured by the eyewear of a user, the position of the remote person is identified, the spoken word are converted to text, and the text is displayed (e.g., in a speech bubble) on an AR display of the eyewear adjacent the remote person.
