摘要： A lighting control apparatus for stage lighting and the like in which lighting values are stored and handled entirely by digital techniques, the apparatus being based on a general-purpose digital computer. The invention also provides a novel method of controlling crossfades from one lighting state to another which is economical in its demands on data handling capacity, since it operates by defining the required changes as a given number of increments thus permitting further control to be by means of addition and subtraction only. A novel clock circuit for use in this incremental cross-fading is described.
