Abstract:
1. A control system including: a camera for providing a first signal representative of a video sequence captured by the camera; a configuration device, associated with the camera, that is responsive to one or more control signals, the configuration device affecting one or more selective adjustments to the camera in terms of pan and tilt; an input device for generating one or more input signals in response to one or more predetermined manual inputs from an operator, wherein the input signals are indicative of a cursor position and a user designated command; and a controller for providing the control signals, the controller being implemented in a graphical user environment, the graphical user environment being configured to provide a graphical user interface for display to the user, the graphical user interface including: wherein the controller is responsive to the input signals such that, based upon the position of the cursor relative to the radial regions and concentric regions and the designated user command, the controller provides to the configuration device control signals that are indicative of: such that the camera performs a selective adjustment in accordance with that predefined adjustment operation and specific speed of camera movement, and wherein: wherein, for each radial region that corresponds to a predefined adjustment operation in terms of a combination of pan movement and tilt movement, the relative pan/tilt weighting is dependent on the specific location of the cursor within the region; wherein the graphical user interface additionally includes one or more zoom functionality regions corresponding to zoom commands, these zoom functionality regions being centrally defined in the image area, and wherein the controller is responsive to the input signals such that, responsive to an input signal indicative of a user designated command and cursor position within one of these zoom functionality regions, the controller provides to the configuration device control signals that are indicative of: a zoom operation; a direction of zoom operation; and a specific speed of rate of change of zoom operation dependent on the position of the cursor within the image area; and wherein, during a zoom operation, dragging the cursor away from the center of the image area increases the rate of change of zoom operation, and dragging the cursor across a boundary between top and bottom halves of the image area reverses a direction of zoom operation.
