摘要： Systems and methods for overlaying a second image/video data onto a first image/video data are described herein. The first image/video data may be intended to be rendered on a display with certain characteristics—e.g., HDR, EDR, VDR or UHD capabilities. The second image/video data may comprise graphics, closed captioning, text, advertisement—or any data that may be desired to be overlaid and/or composited onto the first image/video data. The second image/video data may be appearance mapped according to the image statistics and/or characteristics of the first image/video data. In addition, such appearance mapping may be made according to the characteristics of the display that the composite data is to be rendered. Such appearance mapping is desired to render a composite data that is visually pleasing to a viewer, rendered upon a desired display.

摘要： Representation and coding of multi-view images using tapestry encoding are described for standard and enhanced dynamic ranges compatibility. A tapestry comprises information on a tapestry image, a left-shift displacement map and a right-shift displacement map. Perspective images of a scene can be generated from the tapestry and the displacement maps. Different methods for achieving compatibility are described.

摘要： Motion characteristics related to the images are determined. A motion characteristics metadata portion is generated based on the motion characteristics, and is to be used for determining an optimal FRC operational mode with a downstream device for the images. The images are encoded into a video stream. The motion characteristics metadata portion is encoded into the video stream as a part of image metadata. The video stream is transmitted to the downstream device. The downstream receives the video stream and operates the optimal FRC operational mode to generate, based on the images, additional images. The images and the additional images are rendered on a display device at an image refresh rate different from an input image refresh rate represented by images encoded in the video stream.

摘要： One or more derived versions of image content may be obtained by interpolating two or more source versions of the same image content. A derived version may be targeted for a class of displays that differs from classes of displays targeted by the source versions. Source images in a source version may have been color graded in a creative process by a content creator/colorist. Interpolation of the source versions may be performed with interpolation parameters having two or more different values in two or more different clusters in at least one of the source images. A normalized version may be used to allow efficient distribution of multiple versions of the same content to a variety of downstream media processing devices, and to preserve or restore image details otherwise lost in one or more of the source versions.

摘要： 3D Images may be encoded into reduced resolution image data in a base layer and enhancement layer (EL) image data in one or more enhancement layers. Different types of data compositions may be used in the EL image data. The different types of data compositions may include unfiltered full resolution image data for one or both of left eye and right eye perspectives, or unfiltered full resolution image data for a color channel, e.g., luminance channel, or unfiltered full resolution image data for selected portions of image frames, or fallback data compositions. Based on deciding factors including bitrate requirements and bandwidth constraints, different types of data compositions may be alternatively used by an upstream device to deliver the best possible 3D image data to a wide variety of downstream devices. The upstream device may inform a downstream device of specific types of data compositions with EL image data descriptors.

摘要： Methods are disclosed for adaptive display management using look-up table interpolation. Given a target maximum brightness value for a display, a new look-up table (LUT) for color gamut mapping is determined based on interpolating values from two other pre-computed color gamut LUTs; one computed for a first maximum display brightness larger than the target maximum brightness value, and one computed for a second maximum display brightness lower than the target brightness value. An interpolation scale is computed based at least on the target maximum brightness value and the first maximum display brightness. Methods to reduce the computation load for the translation of RGB data from one color representation (say, ST 2084) to another color representation (say, BT 1866) using fast interpolation methods are also presented.

摘要： A display management processor receives an input image with enhanced dynamic range to be displayed on a target display which has a different dynamic range than a reference display. The input image is first transformed into a perceptually-quantized (PQ) color space. A non-linear mapping function generates a tone-mapped intensity image in response to the characteristics of the source and target display and a measure of the intensity of the PQ image. After a detail-preservation step which may generate a filtered tone-mapped intensity image, an image-adaptive intensity and saturation adjustment step generates an intensity adjustment factor and a saturation adjustment factor as functions of the measure of intensity and saturation of the PQ image, which together with the filtered tone-mapped intensity image are used to generate the output image. Examples of the functions to compute the intensity and saturation adjustment factors are provided.
