Title: Image background detection and removal

Abstract: A method and apparatus for processing an input image to remove background color from the input image is described. The method includes the step of creating a histogram to calculate a dominant color of the input image. Next, the method determines if a threshold luminance is less than a luminance of the dominant color. If so, the method sets the output space values for RGB entries in a CMS table that match the dominant color to white. Finally, the method converts the input image to an output image by referencing the updated CMS table.
