Optical devices and cognitive prosthetics based on novel components for enhanced human vision, selective video/television display, digital processing and/or unique image analysis to modify the image that a user sees and significantly improve the perception of that user are disclosed. What the user sees is responsive to specific perceptual and informational needs of the user in real time. Devices from the parent patents are herein made both more useful in practical day-to-day use and are more widely applicable to improving the ability of a user to perceive visual stimuli.

The present invention relates to an autostereoscopic screen for the simultaneous reproduction of at least two different images, in a manner such that each of these images is visible from at least one of different viewing zones, comprising a subpixel matrix, an optical element and a control unit, wherein the control unit is configured, on the subpixel matrix, to define different subsets of subpixels such that each of the subsets forms a family of parallel strips and is assigned to at least one of the viewing zones, wherein the strips of the different subsets cyclically alternate, and to activate the subpixels in dependence on image data such that each of the images is reproduced on one of the subsets, wherein the optical element has a grating-like structure aligned according to the strips, in order to lead light departing from the subpixels of each of the subsets into the viewing zone assigned to this subgroup. Thereby, the control unit is further configured to define the subsets such that two of subsets overlap, and to activate the subpixels within an intersection of these subsets, in each case with an averaged intensity value. The invention further relates to a suitable method for reproducing image information on an autostereoscopic screen.

A system for generating high-resolution de-warped omni-directional stereo image from captured omni-directional stereo image by correcting optical distortions using projection patterns is provided. The system includes a projection pattern capturing arrangement, a projector or a display, and a de-warping server. The projection pattern capturing arrangement includes one or more omnidirectional cameras to capture projection patterns from the captured omni-directional stereo image from each omni-directional stereo camera. The projector or the display displays the projection patterns. The de-warping server obtain the projection patterns and processes the projection patterns to generate high resolution de-warped omni-directional stereo image by correcting optical distortions in the captured omni-directional stereo image and mapping the captured omni-directional stereo image and the high resolution de-warped omni-directional stereo image.

In one aspect, a computer-implemented method for efficiently rendering and displaying multiple images on an electronic device having an automultiscopic display may generally include detecting, with the electronic device, a position of at least one eye relative to the automultiscopic display. The automultiscopic display may include an array of multipixels, with each multipixel including a plurality of sub-multipixels. In addition, the method may include rendering a viewpoint-specific image for each detected eye position and selectively coloring at least one sub-multipixel within one or more of the multipixels such that colors associated with the rendered viewpoint-specific image are only displayed within a multipixel display zone defined for each of the one or more multipixels with respect to each detected eye position.

Methods, apparatus, devices, and systems for three-dimensional (3D) displaying objects are provided. In one aspect, a method includes obtaining data including respective primitive data for primitives corresponding to an object, determining an electromagnetic (EM) field contribution to each element of a display for each of the primitives by calculating an EM field propagation from the primitive to the element, generating a sum of the EM field contributions from the primitives for each of the elements, transmitting to each of the elements a respective control signal for modulating at least one property of the element based on the sum of the EM field contributions, and transmitting a timing control signal to an illuminator to activate the illuminator to illuminate light on the display, such that the light is caused by the modulated elements of the display to form a volumetric light field corresponding to the object.
