Abstract:
1. A system for parameter based visual characteristic control comprising: input means adapted for receiving image data representative of at least one visual characteristic of an associated image, wherein the image data is inclusive of data representative of at least one of intensity and contrast of the associated image; means adapted for storing data representative of a selected polynomial relationship; storage means adapted for storing at least one selected constant value associated with the selected polynomial relationship, which constant values are chosen so as to define at least one curve associated with the selected polynomial relationship; calculating means adapted for calculating an output value in accordance with the selected polynomial relationship, stored constant values, and received image data; wherein the output value includes a corresponding value thereof as modified by the calculating means; and wherein input data is represented by IN, the output value is represented by OUT, and wherein the at least one selected constant value is represented by C, and wherein the selected polynomial relationship is in the form of:
