An apparatus and method for allowing color adjustments in display devices is disclosed The apparatus comprises a multi-resolution structure for providing color adjustments; and an interpolator for interpolating at least one offset of the multi-resolution structure. An apparatus and method in accordance with the present invention uses a combination of color look-up tables with different levels of resolution, followed by interpolation to provide a display process which has high resolution but utilizes minimal memory. In so doing, memory is used for high-resolution areas only where needed. The multi-resolution structure is a very good approximation to the theoretical mapping table in the areas where it is needed. At the same time, since the high resolution areas are localized, a significant reduction in memory storage is possible.

Apparatus and method for multi-resolution color mapping for display devices

A method and apparatus that allows a display device to adaptively and automatically control display contrast and color is disclosed. The method and system in accordance with the present invention can be described by the following sequential process:

Method and system for adaptive color and contrast for display devices

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.
