ABSTRACT:
A method of data storage, access, interpolation, and display, particularly suited to colorimetry, is disclosed. From a relatively small, multidimensional, device-independent, data base--or "color map"--a subdivision routine is employed to achieve an interpolative data base of relatively immense size. For example, color data input for an image from an RGB monitor is converted to a correlated CMYK printer output. The routine is commercially fast and economical. The iterative process can be selectively controlled to achieve a variety of levels of interpolation and to emulate true interpolation algorithms such as trilinear and quadrilinear interpolation formulas without requiring sophisticated and expensive hardware.
