ABSTRACT:
A color converter capable of conversions between various kinds of color signals appropriate for use over a network (i.e., RGB signals, various luminance/chromaticity separated signals that are expressed by linear transformations of said RGB signals, and CIE LAB signals, which signals may or may not be gamma-corrected) and the internal color signals of devices connected to the network can be realized by rewriting associated coefficients and constants using the same circuit. Accurate color conversions can always be accomplished with an inexpensive system layout.
