Abstract
A method of color detection, in which electrical signals derived from two quantities, preferably orthogonal quantities, for example (R-L) and (B-L) are digitized. A time-shift is applied to the signals, either before or after digitization, and a difference signal is formed between each original signal, and its time-shifted counterpart. The difference signals are then used as a key to a 'lookup' table, to provide an output only when specified combinations of the two difference signals are encountered.
