    Abstract: Techniques for using variable flower assemblies to control light leakage between designated portions of light-emitting elements are provided. In some embodiments, a variable flower assembly (100) comprises a plurality of light-transmissive segments (102-1, 102-2, . . . , 102-6) each may be electronically set to a different light-transparency level. The variable flower assembly substantially forms a tube around a light-emitting element (104) mounted on a first plane. A first edge of each of the light-transmissive segments collectively surrounds the light-emitting element on a second plane substantially parallel to the first plane. A second opposing edge of each of the light-transmissive segments collectively forms an opening of the tube. In some embodiments, a reflective assembly (120) which reflectance level is electronically controllable may surround the variable flower assembly.

    Abstract: Techniques are provided to generate high or wide dynamic range image from two or more input images of different exposure settings by directly merging coefficients derived from the input images in a transform domain. Energy values may be determined from coefficients blocks derived from the input images. The energy values may be compared with thresholds to determine weight factors for the coefficient blocks. An output coefficient block in the transform domain, used in or used to generate the output image, may be determined as a weighted combination of the coefficient blocks in the transform domain derived from the input images. If input images are compressed in transform domain, an output image can be generated without performing decompression in transform domain.

    Abstract: Techniques are provided to encode and decode image data comprising a tone mapped (TM) image with HDR reconstruction data in the form of luminance ratios and color residual values. In an example embodiment, luminance ratio values and residual values in color channels of a color space are generated on an individual pixel basis based on a high dynamic range (HDR) image and a derivative tone-mapped (TM) image that comprises one or more color alterations that would not be recoverable from the TM image with a luminance ratio image. The TM image with HDR reconstruction data derived from the luminance ratio values and the color-channel residual values may be outputted in an image file to a downstream device, for example, for decoding, rendering, and/or storing. The image file may be decoded to generate a restored HDR image free of the color alterations.

    Abstract: Techniques are provided to support a high dynamic range, high brightness, a wide color gamut, and high resolution in an imaging system. The imaging system may use a light source unit to sequentially emit light of different colors. Color-specific frames may be used to drive, directly or indirectly, multiple display panels that comprise at least one monochromatic display panel. Color bleeding and light bleeding may be prevented, or otherwise mitigated, in the imaging system by controlling the sequential emission of light by the light source unit and by controlling display portions of the display panels in the imaging system.

    Abstract: A communications network is described having a class-based queuing architecture. Shared class queues receive packet flows from different customers. In one embodiment, there are eight classes and thus eight shared queues, one for each class. A scheduler schedules the output of packets by the various queues based on priority. Each customer (or other aggregate of packet flows) is allocated a certain space in a class queue based on the customers' Service Level Agreement (SLA) with the service provider. A queue input circuit detects bits in the packet header identifying the customer (or other criteria) and makes selections to drop or pass packets destined for a shared queue based on the customers' (or other aggregates') allocated space in the queue. In another embodiment, the relative positions of the nodes in the network are taken into account by each node when dropping packets forwarded by other nodes by detecting a node label (or other ID code) so that packets from the various nodes are dropped in a more fair way when there is congestion in the network, irrespective of the “passing ” node's position relative to the other nodes.

    Abstract: Techniques for displaying images of different dynamic ranges in a display system are provided. In some embodiments, images that have a number of dynamic ranges may be normalized to a configured dynamic range that corresponds to the full intensity reproduction capability of the device. The configured dynamic range may be wider, greater, or deeper than the relatively limited dynamic range.
