Claim 14:
15. A method for generating a lookup table using curve sampling implemented by a computing device, the method comprising:
deriving samples at evenly spaced intervals along a y-axis relative to a curve, the curve defining how at least one visual characteristic of pixels is transformed to obtain a desired visual effect;
identifying, for each of the derived samples, a value relative to the curve along an x-axis;
designating evenly spaced sample values along the x-axis and, for each of the sample values, defining an index value for the lookup table using a largest one of the identified values relative to the curve along the x-axis not greater than the sample value;
generating a slope parameter portion for the lookup table that includes a plurality of slope values, each of the plurality of slope values specifying a slope between consecutive ones of the index values; and
maintaining the index values and the slope parameter portion in storage as the lookup table, the lookup table useable to transform digital visual content into transformed digital content having the desired visual effect.
