Abstract:
1. A method of controlling operation of a camera using an input device and a control system, the method comprising: providing an input device for a user to provide input for controlling operation of a camera, the input device comprising a manipulable control having a neutral position at which the input device provides no input signal; establishing a threshold perimeter around the neutral position of the input device; receiving, at the control system, a first input signal from the input device, the first input signal resulting from manipulation of the manipulable control; determining whether the manipulable control is within the threshold perimeter; determining whether the manipulable control is moving away from the neutral position; based on a determination that the manipulable control is within the threshold perimeter and is not moving away from the neutral position, processing the first input signal to produce an output signal describing a time-dependent output curve that simulates a varying position of the manipulable control over a specified period of time, the time-dependent output curve being defined by a first, actual position x transmitting the output signal to control operation of the camera.
