Apparatus and methods are provided that employ one or more of a variety of techniques for reducing the time required to display high resolution images on a high dynamic range display having a light source layer and a display layer. In one technique, the image resolution is reduced, an effective luminance pattern is determined for the reduced resolution image, and the resolution of the effective luminance pattern is then increased to the resolution of the display layer. In another technique, the light source layer's point spread function is decomposed into a plurality of components, and an effective luminance pattern is determined for each component. The effective luminance patterns are then combined to produce a total effective luminance pattern. Additional image display time reduction techniques are provided.

Rapid estimation of effective illuminance patterns for projected light fields

A display has a screen which incorporates a light modulator. The screen may be a front projection screen or a rear-projection screen. The screen is illuminated with light from a light source comprising an array of controllable light-emitters. The controllable-emitters and elements of the light modulator may be controlled to adjust the intensity of light emanating from corresponding areas on the screen. The display may provide a high dynamic range.

The present disclosure relates to speech recognition systems and methods that enable personalized vocal user interfaces. More specifically, the present disclosure relates to combining a self-learning speech recognition system based on semantics with a speech-to-text system optionally integrated with a natural language processing system. The combined system has the advantage of automatically and continually training the semantics-based speech recognition system and increasing recognition accuracy.

System and method for implementing a vocal user interface by combining a speech to text system and a speech to intent system

A backlight for a display comprises a plurality of independently controllable light sources and inclined surfaces inclining in a radially outward direction from each light source for shaping the distribution of emitted light. The light sources may each comprise a group of differently-colored light emitters. The backlight may include light integrators configured to mix light of the differently-colored light emitters. Inclined surfaces for shaping the distribution of emitted light may be arranged around exits of the light integrators.

Optical mixing and shaping system for display backlights and displays incorporating same

Dual modulator displays are disclosed incorporating a phosphorescent plate interposed in the optical path between a light source modulation layer and a display modulation layer. Spatially modulated light output from the light source modulation layer impinges on the phosphorescent plate and excites corresponding regions of the phosphorescent plate which in turn emit light having different spectral characteristics than the light output from the light source modulation layer. Light emitted from the phosphorescent plate is received and further modulated by the display modulation layer to provide the ultimate display output.

Locally dimmed quantum dot display

Optical mixing and shaping system for display backlights and displays incorporating the same

A locally dimmed display has a spatial light modulator illuminated by a light source. The spatial light modulator is illuminated with a low resolution version of a desired image. The illumination may comprise a series of lighting elements that vary smoothly from one element to another at the spatial light modulator.

Projection displays

Apparatus and methods are provided that employ one or more of a variety of techniques for reducing the time required to display high resolution images on a high dynamic range display having a light source layer and a display layer. In one technique, the image resolution is reduced, an effective luminance pattern is determined for the reduced resolution image, and the resolution of the effective luminance pattern is then increased to the resolution of the&#x2014;display layer. In another technique, the light source layer's point spread function is decomposed into a plurality of components, and an effective luminance pattern is determined for each component. The effective luminance patterns are then combined to produce a total effective luminance pattern. Additional image display time reduction techniques are provided.

Apparatus and methods for mapping video signal parameters such as tone and color may be applied at various points in a video generation and delivery pipeline. apparatus may be configured to control mappings based on a range of inputs which may include one or more of: ambient conditions, user inputs, control information, adaptation models. Apparatus and methods may be applied to display video or other images so as to preserve a creative intent embodied in video or other image data.

Display management methods and apparatus

A camera has two distinct image sensor arrays. The image sensor arrays are at least one of different types and different resolutions. The image sensor arrays have different dynamic ranges such that one of the image sensor arrays is a high dynamic range image sensor array configured to capture a wider range of light intensity than the other of the image sensor arrays. The camera has an imaging mechanism configured to combine information collected by each of the image sensor arrays to produce a high dynamic range image. The image sensor arrays include one low resolution image sensor array having a high dynamic range, and one high resolution image sensor array having a normal dynamic range smaller than the high dynamic range wherein luminance values within the normal dynamic range represent a subset of luminance values within the high dynamic range.

Electronic camera having multiple sensors for capturing high dynamic range images and related methods

Parallax in an optical device is reduced by apply one or a combination of several disclosed techniques, including reduced solid angle or increased collimation of light sources, increased diffusion/scattering at an output of the device, and/or reflective structures for collimation and containment of reflected light. The techniques are advantageously applied to a backlight LCD display, and particularly to high dynamic range dual modulation displays.
