Abstract:
A camera support or head has a pan frame pivotably attached to a support hub. The support hub is attached to a camera crane or similar apparatus. The pan frame has first and second spaced apart and parallel adjustable length pan arms. A pan motor is attached to the pan frame and adapted to pivot the pan frame about a pan axis relative to the support hub. A tilt frame is pivotably attached to the pan frame. The tilt frame may include first and second spaced apart and parallel adjustable length tilt arms attached to opposite ends of a camera mounting plate. A tilt motor is attached to the tilt frame and to the pan frame and is adapted to pivot the tilt frame about a tilt axis perpendicular to the pan axis. The adjustable length tilt arms allow the camera head to extended to accommodate cameras requiring more vertical clearance. The adjustable length tilt arms allow the camera platform to be moved to better locate the center of gravity of the camera on the tilt axis, for more balanced loading.
