Abstract

A man to machine interface for the control of video or motion picture camera movement for use with a camera aiming system which can reproduce a specific camera movement any number of times. The interface moves the camera in the pan or tilt axis giving an operator a natural control feel while actually driving the camera movement with a motor drive. A shaft encoder detects the velocity of the motor drive and stores such information over time in a memory. The data stored in the memory may be read out at a later time and used by the motor drive to replicate the movement of the camera.
