Claim One:
1. A method of dynamically controlling an imager of a video camera to provide, with selectable resolution, image information relating to one or more regions of interest in a scene processed by the video camera, the imager having a specified maximum number of image pixels that establish a characteristic maximum image resolution of the imager and having a number of image pixels from which are produced video data that represent the scene, comprising: controlling the imager to acquire high resolution video data representing substantially the specified maximum number of image pixels that capture a full field of view of the scene controlling the imager to acquire a first series of sub-sampled video data from the high resolution video data corresponding to the scene at a first image resolution, the first series of sub-sampled video data produced by a first subset of image pixels composed of fewer image pixels than the specified maximum number of image pixels of the imager; analyzing the sub-sampled video data in the first series to detect a region of interest within the scene; and controlling the imager to acquire a second series of sub-sampled video data from the high resolution video data corresponding to the detected region of interest within the scene at a second image resolution thereby non-uniformly sub-sampling at least one frame of the video data, the second image resolution being higher than the first image resolution, the sub-sampled video data in the second series representing a windowed view of the detected region of interest in the scene.
