Abstract
A projector controller includes an object detector and control electronics, and is configured to protect audience members from intense light imposing an exclusion zone in front of a projector. The object detector is configured to optically sense a presence of an object in a detection region beneath the exclusion zone and above the audience members. The control electronics is configured to control the projector when the object detector indicates the presence of the object in the detection region. A method for protecting audience members from intense light imposing an exclusion zone in front of an output of a projector includes: (i) optically sensing a presence of an object in a detection region between the exclusion zone and the audience members, and (ii) controlling the projector when the presence of the object is sensed in the detection region.
