REFERENCE CARD FOR SCENE REFERRED METADATA CAPTURE

摘要

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.
