Creating a look-up table which converts color image data from a
device-independent color space to a device-dependent color space, by
determining a range of lightness values corresponding to a lightness
value of a target data point in device-independent color space, searching
a predetermined set of data points in device-independent color space to
obtain a selected set of data points, each selected data point having a
lightness value within the determined range of lightness values and
having corresponding device-dependent component values within a
predetermined tolerance level of the component values of a
previously-determined device-dependent data point, performing a weighted
interpolation on the device-dependent component values corresponding to
the selected set of data points to calculate an interpolated data point
which is in device-dependent color space, and entering the interpolated
device-dependent data point into a look-up table entry corresponding to
the device-independent target data point.
