摘要： In an embodiment, a first display monitor communicates with a second display monitor to determine a common set of display capabilities that are supported by both the first display monitor and the second display monitor. One or more first color grading instructions for one or more first images are received from a first user. In response to receiving the one or more first color grading instructions, the one or more first images are color graded with the one or more first color grading instructions to generate one or more first color graded images. The one or more first color graded images are rendered on the first display monitor. In addition, the one or more first color graded images are caused to be rendered on the second display monitor.

摘要： Image encoding is described. Log-luminances in an HDR input image are histogrammed to generate a tone-map, along with which a log global tone-mapped luminance image is computed. The log global tone-mapped luminance image is downscaled. The log-luminances and the log global tone-mapped luminance image generate a log ratio image. Multi-scale resolution filtering the log ratio image generates a log multi-scale ratio image. The log multi-scale ratio image and the log luminances generate a second log tone-mapped image, which is normalized to output a tone-mapped image based on the downscaled log global tone-mapped luminance image and the normalized image. The HDR input image and the output tone-mapped image generate a second ratio image, which is quantized.

摘要： 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 comprises a plurality of light-transmissive segments each may be electronically set to a different light-transparency level. The variable flower assembly substantially forms a tube around a light-emitting element 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 which reflectance level is electronically controllable may surround the variable flower assembly.

摘要： Techniques are provided to provide various pulse width modulation (PWM) schemes to embodiments of dual modulator display systems that may comprise a backlight of individually addressable and controllable light emitters. The backlight provides illumination to a light modulator for further conditioning of the light to be presented to a viewer. The backlight may be striped and each stripe is assigned a PWM scheme that effectively increases the bit depth of the controller for each stripe. The display system may allow a better matching of PWM periods to LCD frame rates to reduce visual artifacts. In another embodiment, the display system may detect a small bright feature to be rendered in the image data and, with a pre-assignment of light emitters to different partitions, the backlight controller may drive a subset of the light emitters according to the partitions.

摘要： 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.
