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 acquired by the video camera, the imager having a specified maximum number of image pixels that establish a characteristic maximum image resolution of the imager, comprising: controlling the imager to acquire a first series of sub-sampled video data corresponding to a first field of view of the scene at a first image resolution; analyzing the sub-sampled video data in the first series to detect a region of interest in the scene; controlling the imager to acquire a second series of sub-sampled video data corresponding to a second field of view of the scene at a second image resolution, the sub-sampled video data in the second series representing, at the second image resolution, a windowed view of the detected region of interest in the first field of view of the scene; and each of the first and second series of sub-sampled video data corresponds to fewer image pixels than the specified maximum number of image pixels of the imager.
