Abstract:
1. A method of creating a multiprimary lookup table, the method comprising: defining a set of color points, each represented by a data value for each of a first number of primary signals; selecting a color point from the set of color points; representing the color point by at least two unique converted color points, each converted color point having a data value for each of a second number of primary signals, wherein the second number is greater than the first number; computing a quality measure for the at least two unique converted color points, the quality measure influenced by additional converted color points representing similar color points; further selecting one converted color point for each color point based on the quality measure; repeating the selecting, representing, computing, and further selecting steps for each color point in the set of color points; storing the selected converted color points in a lookup table comprising a semiconductor memory array for converting the set of color points from a representation in terms of the first number of primary signals to a representation in terms of the second number of primary signals.
