Abstract

The invention contemplates wireless remote-control of a camera or the like, as from within the field of view of the camera, and using control radiation which is essentially outside the spectral response of the camera. Control is effected by selective operation of a pulsed transmitter of the control radiation, and by generating in a receiver at the camera an electrical signal for camera control. Various modifications and embodiments are disclosed, including selective remote-control of one or more different camera functions.
