    Abstract: A highlight mask is generated for an image to identify one or more highlights in the image. One or more highlight classifiers are determined for the one or more highlights in the image. One or more highlight gains are applied with the highlight mask to luminance amplitudes of pixels in the one or more highlights in the image to generate a scaled image. The one or more highlight gains for the one or more highlights are determined based at least in part on the one or more highlight classifiers determined for the one or more highlights.

    Abstract: A spherical image of a spatial environment is received and contains spherically arranged pixel values indexed by a time value. The spherical image is represented in a content creation coordinate system in reference to a spatial position in the spatial environment. The spatial position is indexed by the time value. A spatial relationship is determined between the content creation coordinate system and a spherical image reference coordinate system. Based at least in part on the spatial relationship and the spherically arranged pixel values, spherical distributions of image metadata are determined for the spherical image.

    Abstract: The present invention provides a cinema screen that improves audience perception of brightness at, for example, a premium theater without additional illumination cost. The screen is produced from materials that also help mitigate speckle from laser illumination. The screen has properties and includes structures that may be tuned to the specific capabilities of the projection system, arrangement of the theater, and projector (and angle of projection, angle of viewing). Light reflected from the screen are direct toward audience members and away from walls and ceilings.

    Abstract: Several embodiments of a media processor for the creation of metadata from a set of images are given. The media processor receives a set of image data and computes metadata from the image data. The metadata may comprise statistical data based on the image data; from which the media processor may generate and store a multi-scale version of the metadata. The metadata may comprise statistical attributes derived directly from the image data or statistical attributes derived from image appearance correlates of the image data. The media processor may generate a subsampled set of the metadata and the subsampled set may be stored in an efficient data structure, such as a pyramidal structure. The pyramidal structure may be generated from spatial image information, from temporal image information or from spatial-temporal image information.

    Abstract: A plurality of input images in an input video signal of a wide dynamic range is received. A specific setting of global light modulation is determined based on a specific input image in the plurality of input images. The specific setting of global light modulation produces a specific dynamic range window. A plurality of input code values in the specific input image is converted to a plurality of output code values in a specific output image corresponding to the specific input image. The plurality of output code values produces the same or substantially the same luminance levels as represented by the plurality of input code values. Any other pixels in the specific input image are converted to different luminance levels in the specific output image through display management.

    Abstract: Systems and methods for performing color mapping operations. One system includes a processor to perform post-production editing of image data. The processor is configured to identify a first region of an image and identify a second region of the image. The first region includes a first white point having a first tone, and the second region includes a second white point having a second tone. The processor is further configured to determine a color mapping function based on the first tone, apply the color mapping function to the second region of the image, and generate an output image.

    Abstract: Systems and methods are disclosed for dynamically adjusting the backlight of a display during video playback. Given an input video stream and associated minimum, average, or maximum luminance values of the video frames in the video stream, values of a function of the frame min, mid, or max luminance values are filtered using a temporal filter (320) to generate a filtered output value for each frame. The instantaneous dynamic range of a target display is determined (330) based on the filtered output value and the minimum and maximum brightness values of the display. A backlight control level is computed based on the instantaneous dynamic range, and the input signal is tone mapped by a display management process to be displayed on the target display at the selected backlight level. The design of a temporal filter based on an exponential moving average filter and scene-change detection is presented.
