Patent Images
1. A method for automatically and adaptively controlling contrast and color of a display device, comprising:
- computing a normalized histogram of a current image;
computing degrees of correlation between the normalized histogram and a number of template histograms;
sorting the template histograms based upon the associated degrees of correlation;
selecting a number of the best correlated template histograms based on the sorting;
associating each of the selected template histograms with a corresponding transfer function;
blending the transfer functions to form a blended transfer function; and
applying the blended transfer function to the current image.

Abstract
Automatically and adaptively controlling contrast and color of a display device by computing a normalized histogram of a current image, computing degrees of correlation between the normalized histogram and a number of template histograms, sorting the template histograms based upon the associated degrees of correlation, selecting a number of the best correlated template histograms based on the sorting, blending the selected the transfer functions associated with the selected template histograms to form a blended transfer function, and applying the blended transfer function to the current image.
