Systems and methods for appearance mapping for compositing overlay graphics

A system for overlaying a second image over a plurality of first images, said system comprising:

• a display management module capable of receiving said plurality of first images, which are temporally related and form a first scene;
• a compositor module capable of:
• receiving said second image, the second image differing in size and dynamic range from each of the plurality of the first images;
• mapping a dynamic range of the first scene to a dynamic range of a display to generate adjusted first images, wherein said mapped dynamic range of the first scene is different from a maximum dynamic range of the display;
• and
• performing appearance mapping said second image to form an adjusted second image, said adjusted second image differing in dynamic range from said second image, wherein performing appearance mapping of said second image (i) is performed according to mapping information about the mapped dynamic range of the first scene and image statistics regarding the second image, the image statistics including at least one of average luminance, minimum luminance, mean luminance, maximum luminance, dynamic range, reflective white, color temperature, whitepoint, color gamut and color palette and (ii) involves selecting a dynamic range based on both the dynamic range of the first scene and the capabilities of the display;
• and
• a mixing module capable of mixing said adjusted second image onto at least one of said adjusted first images to form composite images, said composite images intended to be rendered upon said display.
