Abstract: Methods and apparatuses for performing gamma corrections to maintain a plurality of colors substantially consistent with a color point. In one aspect of the present invention, a method to generate correction functions for performing color correction for a device for signals of different color components in a color space includes: generating a first correction function for a first color component in the color space; and generating second correction functions for second color components in the color space by reducing first color differences between a target white point and white points of a plurality of grays corrected by the first and second correction functions. The second color components are the color components in the color space other than the first color component. The first color differences are minimized relative to a chromaticity diagram.

Abstract: A method and system for compressing and color transforming image data are presented. Color transformation is a process whereby perceptional differences between the expressions of images in color devices are compensated. By transforming a compressed version of the image data, the amount of time in which it takes to perform color transformation can be reduced. Selection of compression techniques which maintain color characteristics of the image data in its compressed form permits the usage of color transformation techniques which already exist for the image data in its uncompressed form. The inventive techniques can be applied either prior to, or after, storage of the image data in an intermediate media or transmission from one device to another.

Abstract: An apparatus and method for imaging using context sensitive pixel modulation wherein a modulator dynamically examines the neighboring pixels to the current pixel being imaged and uses the neighboring pixel information in determining the specific modulation pattern for the current pixel.

Abstract: An apparatus and method for producing high definition output images using an encoding scheme for differentiating between differing data types and context sensitive pixel modulation for dynamically shifting pixel growth direction during post-processing manipulation of the data.

Abstract: An apparatus and method for enabling intelligent post-processing of differing data types wherein different types of data are encoded with different sets of values such that a post-processing apparatus is able to recognize and delineate between the different types and perform post-processing procedures on only the appropriate type.
