AbstractA foveated electronic camera employing a spatial-frequency spectrum analyzer and data-reduction means utilizing movable spatial windows for converting a high-resolution, wide field-of-view image into a group of subspectrum band images ranging in resolution and field of view from a lowest-resolution image of the entire field of view to a highest-resolution image of a selectably positionable smallest spatial subregion of the entire field of view. Such a camera is useful in a surveillance camera system and in a robotic system, by way of examples.
