  • Method for contrast mapping of digital images using a variable mask
    Patent number: 6804409
    Abstract: A method is disclosed for changing the dynamic range of an original input image to more closely match the dynamic range of the medium used for a reproduction. The method includes creating an output image by preserving small contrast differences between different areas of the original input image and limiting the maximum contrast differences between different areas of the original input image. The method also includes creating a mask by subtracting the original input image from the output image, scaling the mask, and creating a new output image by adding the scaled mask to the original input image.
