Abstract

A method that generates a chromakey image and then generates a color corrected, spill suppressed chromakey image. The application identifies the edges of non-transparent objects in the image and determines whether the edges are dark. If the edges are dark, then the application subtracts the color corrected, spill suppressed chromakey image from the chromakey image. The subtraction generates an outline image that includes a bright outline of the objects with the dark edges, while the objects themselves in the outline image are almost entirely black. The application then darkens, based on the outline image, the pixels of the color corrected, spill suppressed chromakey image.

Dependent claims

A method of adjusting an image, the method comprising:

receiving a source image that includes a first set of green pixels with a first set of color values and a second set of green pixels with a second set of color values;
generating a first greenscreen image by rendering the first set of green pixels transparent;
generating a second spill-suppressed color corrected greenscreen image by color adjusting the second set of green pixels;
generating an outline image by subtracting the second spill-suppressed color corrected greenscreen image from the first greenscreen image;
generating a third greenscreen image by selectively darkening pixels of the second spill-suppressed color corrected greenscreen image according to the brightness of corresponding pixels of the outline image.
