Abstract: Systems for displaying images in a cinema setting can include components to reduce screen-door effect. The systems can include an array of light emitting sources or other active sources of light. In one example, the light emitting source emit pixels of light to a projection lens to project an image represented by the projection lens and a baffle and an aperture stop can block part of the light from the sources that exceeds an allowable cone angle of acceptable of the system. In another example, a display includes the array of light emitting sources and additional elements, such as diffuser elements, positioned in front of the array of light emitting sources.

Abstract: Systems for displaying images in a cinema setting can include components to reduce screen-door effect. The systems can include an array of light emitting sources (102) or other active sources of light. In one example, the light emitting source emit pixels of light to a projection lens (124) to project an image represented by the projection lens and a baffle (150) and an aperture stop (118) can block part of the light from the sources that exceeds an allowable cone angle of acceptable of the system. In another example, a display includes the array of light emitting sources and additional elements, such as diffuser elements, positioned in front of the array of light emitting sources.

Abstract: A light emitting display can be formed from tiles mounted within a certain distance range with respect to each other and with an established blending region positioned towards the edges of the tiles. A tile can be a matrix of light emitting elements, such as LEDs, OLEDs, quantum dots, or other element that emits light. The tolerance of spacing between tiles can allow for less precision in alignment during installation in a theatre, thereby reducing display assembly cost but still maintaining a display for displaying an image at a high quality with reduced or eliminated appearance of visual artifacts between tiles.

Abstract: An active display can be used in a theatre with reduced screen-door effect. For example, the active display can have a structure, such as a diffuser structure, or a diffuser and mask structure, that can have, or appear to have, transmissive areas and opaque areas to reduce the audience from detecting gaps or other non-light sources in the active display. The active display may additionally or alternatively have audio ports to allow sound to pass through the active display and appear to the audience as if the sound is coming from the active display.

Abstract: An active display (102) can be used in a theatre environment (100) in which content to be displayed by the active display (102) can be delivered wirelessly using emitters (118). The active display (102) can include tiles (104a-104d) with detectors (106a-106d) that can detect the wireless signals. The active display (102) can include circuitry that can interpret instructions from the wireless signals for controlling the output (108a-108d) of pixels on the tiles.

Abstract: An active display can have an increased color gamut and include a group of LED packets that each form a sub-pixel and that together form a pixel for the display. Each LED packet includes at least a red primary color LED, a greed primary color LED, and a blue primary color LED. Each LED can be associated with an intensity value to control the intensity of primary light outputted by the LED. The group of LED packets can output light in a color gamut of a color space for the active display. Each LED packet of the group of LED packets, individually, is configured to output light in the color gamut of a subset of the color space. The active display can display a visual media presentation to an audience. An increased fraction of LEDs from a production batch can be used in the active display.

Abstract: A dual projection system can align displayed images using an alignment pattern. The alignment pattern can be used to modify part of an image content frame of an image data sequence. Two image data sequences can be spatially aligned based on the modification to part of the image content frame using the alignment pattern. An image content frame may be warped and displayed. The displayed warped image content frame can be captured. A set of transformation vectors can be determined based on the captured image content frame and alignment image data. Stored transformation data can be updated using the set of transformation vectors and the updated transformation data can be used to spatially align two image data sequences.

Abstract: Chromatic aberration can be reduced and extreme projection angles can be allowed in a projection system by modifying one color channel of light having a wavelength bandwidth with image data to produce imaged light, causing the imaged light to spread angularly when displaying the imaged light through an optical distorting element onto a screen, and reducing angular spread of the imaged light exiting the optical distorting element by adjusting the wavelength bandwidth.

Abstract: The present invention provides a method of providing a digitally represented visual instruction from a specialist (2) operating a visual instruction device (4) to a user (6) in need of the visual instruction in relation to an object of interest (8) and a system therefore. In the method a first video stream comprising images of the object of interest is recorded by a first mobile device (12) associated with the user. The first video stream is sent (22) to a second mobile device (18) associated with the specialist. A second video stream comprising the visual instruction device is recorded by the second mobile device and a foreground/background segmentation operation and a background replacement operation is performed on the second and first video stream to provide a third video stream comprising images of the visual instruction device with the first video stream as background.
