    Abstract: A wearable device for augmented media content experiences can be formed with a mountable physical structure that has removably mountable positions and component devices that are removably mounted through the removably mountable positions. The component devices can be specifically selected based on a specific type of content consumption environment in which the wearable device is to operate. The mountable physical structure may be subject to a device washing process to which the component devices are not subject to, after the wearable device including the mountable physical structure and the component devices is used by a viewer in a content consumption session in the specific type of content consumption environment, so long as the component devices are subsequently removed from the mountable physical structure.

    Abstract: Techniques for driving a dual modulation display include generating backlight drive signals to drive individually-controllable illumination sources. The illumination sources emit first light onto a light conversion layer. The light conversion layer converts the first light, such as blue or ultraviolet light, into second light, such as white light. The light conversion layer can include quantum dot materials. Liquid crystal display (LCD) modulation drive signals are generated to determine transmission of the second light through individual color subpixels of the display. These LCD modulation drive signals can be adjusted based on one or more light field simulations to account for non-uniform, spatial color shifts. Alternatively, one or more light field simulations based on a uniformity assumption determine intermediate LCD modulation drive signals. A compensation field simulation, using backlight drive signals, is then used to adjust the intermediate LCD modulation drive signal for color correction.

    Abstract: High dynamic range 3D images are generated with relatively narrow dynamic range image sensors. Input frames of different views may be set to different exposure settings. Pixels in the input frames may be normalized to a common range of luminance levels. Disparity between normalized pixels in the input frames may be computed and interpolated. The pixels in the different input frames may be shifted to, or stay in, a common reference frame. The pre-normalized luminance levels of the pixels may be used to create high dynamic range pixels that make up one, two or more output frames of different views. Further, a modulated synopter with electronic mirrors is combined with a stereoscopic camera to capture monoscopic HDR, alternating monoscopic HDR and stereoscopic LDR images, or stereoscopic HDR images.

    Abstract: 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.

    Abstract: 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.

    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 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.
