| Title: |
Lighting Control System with Cue Level Information |
| Abstract: |
A stored-cue lighting-control system for controlling the illumination of a
selected space, such as a stage. The system includes a photodetector for
following the level of illumination in the space. During storing of cue
data associated with a particular cue, related data, regarding the level
of illumination intended to be produced by the cue, is also stored. During
functioning of the system to place different successive cues in the space,
the stored illumination level data is compared with current real-time data
reflecting the actual illumination level then being produced in the space.
An indicator signals any difference noted as a result of this comparison.
