Abstract: A camera stabilizer which can be carried by the camera operator having three masses, one of which is a camera, maintained in positions separate from one another by a frame. Because the three masses are separated, the stabilizer has a high angular moment of inertia making the camera stabilizer less susceptible to unwanted movement. A handle is attached to the frame at approximately the center of gravity of the camera stabilizer and has a gripping axis parallel to the plane of a camera mount.

Abstract: A system for creating a control reference signal for a remote electrical servo device having a movable output unit wherein the velocity and position of the output unit are controlled by the vector magnitude of the control reference signal. This system includes a digital circuit for creating a first fixed analog signal indicative of a known or desired velocity for the unit during a preselected controlled time interval and a second digital means for creating a desired time base positional profile during the preselected time interval. An encoder arrangement is employed for detecting the actual time base positional profile of the servo output unit during the given time interval so that an analog signal generally proportional to the algebraic difference between the actual and desired time base positional digital profile can be created at various times during the time interval.

Abstract: In a composite photography system of the type wherein a foreground camera photographs life-size actors and objects while a background camera photographs scenery on a life-size scale or a scale different from life-size so that when the outputs from both cameras are combined the actor or foreground objects will appear to be located in the scenery filmed by the background camera, it is crucial that the motion of the background camera be slaved to the motion of the foreground camera. The foreground camera is mounted on a yaw and pitch support mechanism which is in turn mounted on a boom that provides movement along the z axis. The boom is carried by a dolly that moves the entire assembly in the x-y plane. Sensors on the dolly detect movement along the five axes of x, y, z, yaw and pitch, and cause the background camera to move its corresponding amount.

Abstract: A system is provided for generating a plurality of light images in different colors from a single laser light source, and moving these varying light images in predetermined paths in response to signals synchronized with music.
