  • Patent number: 7710432
    Abstract: According to an embodiment of the present invention, selective tristimulus corrections to device-independent coordinates are applied using a piecewise linear correction function. The piecewise linear correction function is defined such that a maximum of the piecewise linear correction function occurs at a boundary condition of a corresponding device-dependent color space, and the piecewise linear correction function is linearly reduced to zero or approximately zero as values in the corresponding device-dependent color space approach either a different boundary condition or a neutral axis. By having the piecewise linear correction function reduce linearly to zero or approximately zero, corrections to one region of color smoothly diminish and blend into the other regions of color, thereby substantially preventing the introduction of artifacts or image corruption due to the corrections.
