摘要
A method of reducing the dynamic range of an input image for effectively rendering the input image on an output display medium, the method comprises the steps of extracting detail signals and coarse signals from the input image; generating contrast gain-control signals from the input image by detecting coarse scale edges; modifying the detail signals according to the contrast gain signals; and, adding the modified detail signals to the coarse signals to obtain an output image.
