Claim One:
1. A method for acquiring multi-scale images, the method comprising: tracking an object of interest moving through a field of view of a master camera; dividing the field of view of the master camera into a plurality of independent, non-overlapping, predefined regions of interest; calibrating a steerable slave camera to obtain multi-scale images of the object of interest by associating the steerable camera with one of the plurality of predefined regions of interest within the field of view of the master camera and setting pan tilt and zoom parameters for the slave camera so that a field of view associated with the slave camera is equal in size to its associated regions of interest; determining a predicted future path for the object of interest, the predicted further path passing through the predefined region of interest associated with the steerable camera; using the slave camera in accordance with the calibration to track the object of interest through the associated predefined region of interest; and obtaining multi-scale video of the object of interest using the slave camera; wherein the step of calibrating a steerable slave camera comprises calibrating a plurality of steerable cameras such that each steerable camera is associated with a separated predefined region of interest within the field of view of the master camera along the predicted future path of the object of interest.
