Abstract: Scene-referred metadata comprising correspondence relationships between coded values used in generated images and reference values defined independent of any specific image may be provided as a part of image metadata for the generated images. Downstream image processing devices or image rendering devices may use the scene-referred metadata to perform image processing or rendering operations. When coded values of input images are altered in corresponding output images, the scene-referred metadata may be updated with new coded values used in the output images. Reference values refer to reference color values or reference gray levels. Coded values refer to color values or gray levels coded in pixels or sub-pixels of one or more images.

Abstract translation: 可以提供包括在生成的图像中使用的编码值与独立于任何特定图像的参考值之间的对应关系的场景参考元数据作为生成图像的图像元数据的一部分。 下游图像处理设备或图像渲染设备可以使用场景参考的元数据来执行图像处理或呈现操作。 当在相应的输出图像中改变输入图像的编码值时，可以用在输出图像中使用的新的编码值更新场景参考的元数据。 参考值是指参考颜色值或参考灰度级。 编码值是指以一个或多个图像的像素或子像素编码的颜色值或灰度级。

Abstract: Several embodiments of display systems that use narrowband emitters are disclosed herein. In one embodiment, a display system comprises, for at least one primary color, a plurality of narrowband emitters distributed around the primary color point. The plurality of narrowband emitters provides a more regular power vs. spectral distribution in a desired band of frequencies.

Abstract: Embodiments of the invention relate to a display operable in 2D and 3D display modes. Methods and apparatus are provided for adjusting the colors and brightness of the image data and/or intensity of the display backlight based on the current display mode and/or color-grading of the image data. For example, when switching to a 3D display mode a color mapping may be performed on left and right eye image data to increase color saturation in particular regions, and/or the backlight intensity may be increased in particular regions to compensate for lower light levels in 3D display mode.
