ABSTRACT:
A camera-position control is disclosed which includes a multi-axial, manual control of a generator for an electronic pointer for generating a spot at the focus of interest of a scene and for directing the spot to accompany a moving subject or to migrate to a second focus of interest, the signal generated for moving said spot being coupled to a multi-axial, camera-positioning drive circuit which includes tachometer generators whose output is imposed on the generated positioning signal for their respective axes to oppose that signal and thereby impose a rate control on the camera-positioning drive.
