Abstract
A new circuit is connected to the pan servo amplifier 38 of a camera remote pan head 44 for the purpose of eliminating the need for manual backpan. The circuit comprises a tachometer 20 mounted on the pan arm of a camera crane or jib arm 28 and connected to switch 32 and potentiometers 34 and 36. The switch and potentiometers select between three options for operation: an off position, a one to one reverse correspondence between the panning movement of the crane arm 28 and the panning movement of the pan head 44, and a variable reverse correspondence between the panning movement of the crane arm 28 and the panning movement of the remote pan head 44. The output is summed to a servo amplifier 38 which drives the remote head pan motor/tachometer 40. A number of means for alternative implementation are also suggested.
