Claim 7:
8. A system implemented by a computing device, the system comprising:
a transformation module implemented at least partially in hardware of the computing device to generate transformed digital visual content by transforming one or more pixels of digital visual content using a lookup table, the lookup table generated by:
identifying a curve defining how at least one visual characteristic of the one or more pixels is transformed;
deriving samples of the curve taken at evenly spaced intervals along a y-axis relative to the curve, and 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; and
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

a display module implemented at least partially in hardware of the computing device to display the transformed digital visual content.
