    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: 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-corrected IPT color space. A non-linear mapping function generates a first tone-mapped signal by mapping the intensity of the input signal from the reference dynamic range into the target dynamic range. The intensity (I) component of the first tone-mapped signal is sharpened to preserve details, and the saturation of the color (P and T) components is adjusted to generate a second tone-mapped output image. A color gamut mapping function is applied to the second tone-mapped output image to generate an image suitable for display onto the target display. The display management pipeline may also be adapted to adjust the intensity and color components of the displayed image according to specially defined display modes.

    Abstract translation: 显示管理处理器接收具有增强的动态范围的输入图像，以显示在具有与参考显示不同的动态范围的目标显示器上。 输入图像首先被转换成感知校正的IPT颜色空间。 非线性映射函数通过将来自参考动态范围的输入信号的强度映射到目标动态范围来生成第一音调映射信号。 第一音调映射信号的强度（I）分量被锐化以保留细节，并且调整颜色（P和T）分量的饱和度以产生第二色调映射输出图像。 将色域映射函数应用于第二色调映射输出图像，以产生适于在目标显示器上显示的图像。 显示管理流水线也可以根据特定的显示模式调整显示图像的强度和颜色分量。

    Abstract: 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.

    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: A display apparatus, a display management module and a method for ambient light compensation are described. The display management module is configured to receive an input video signal comprising a sequence of video frames and to determine whether a current video frame of the sequence of video frames immediately follows a scene change. The display management module is further configured to adjust ambient light compensation applied to the input signal in dependence on the signal indicative of intensity of ambient light only in response to determining that the current video frame of the sequence of video frames immediately follows a scene change.
