摘要:
Compression transforming video into a compressed representation (which typically can be delivered at a capped pixel rate compatible with conventional video systems), including by generating spatially blended pixels and temporally blended pixels (e.g., temporally and spatially blended pixels) of the video, and determining a subset of the blended pixels for inclusion in the compressed representation including by assessing quality of reconstructed video determined from candidate sets of the blended pixels. Trade-offs may be made between temporal resolution and spatial resolution of regions of reconstructed video determined by the compressed representation to optimize perceived video quality while reducing the data rate. The compressed data may be packed into frames. A reconstruction method generates video from a compressed representation using metadata indicative of at least one reconstruction parameter for spatial regions of the reconstructed video.

Techniques for configuring light conversion materials such as quantum dots in a display system are described. A display system includes light source components that emit a first light. The display system further includes a light converter illuminated by the first light. The light converter converts the first light into second light comprising one or more color components to support a specific color gamut. The second light forms, based at least in part on image data for images to be rendered, an emission pattern that varies with space and time.

A display is backlit by a source having spatially modulated luminance to attenuate illumination of dark areas of images and increase the dynamic range of the display.

Embodiments of the present invention comprise systems, methods and devices for increasing the perceived brightness of an image. In some embodiments this increase compensates for a decrease in display light-source illumination.

摘要:
An image processing system processes light conveying visual pattern information represented by individual light rays. The system includes an optical assembly having an input surface and an output surface. The input and output surfaces define a plurality of input and output positions, respectively, for the light rays to enter and exit, respectively, the assembly. The assembly includes a light-shifting apparatus operable so that a respective one of the light rays entering a respective one of the input positions is selectively shiftable by the apparatus in a first direction and, subsequently, in a second direction angled with respect to the first direction from a preceding one to another of the output positions. The assembly is further operable so that following each shifting operation, a respective one of the light rays transmitted by the assembly from an arbitrarily selected one of the output positions is solely derived from the light received from a single one of the input positions.

Techniques for extracting light from a light guide are described. In some embodiments, a light source comprises a light guide configured to trap first light through total internal reflection. The light source may further comprise a plurality of light extractors configured to extract at least a portion of the first light upon establishing optical contact with the light guide. The light source is configured to control individual light extractors in the plurality of light extractors to make optical contact with the light guide. Quantum dots may be used with the light source to regenerate light, within desired frequency band, from the at least a portion of the first light.
