1. A method for zooming a camera, comprising the steps of: (A) receiving an electronic image from an electro-optical sensor, wherein said electronic image has an initial resolution; (B) generating a final image in an output signal by decimating said electronic image per a decimation factor, wherein (i) said final image has a final resolution and (ii) said final resolution is smaller than said initial resolution; and (C) changing a zoom factor of said final image continuously over a range by both (i) adjusting said decimation factor and (ii) generating a first signal that commands said electro-optical sensor to adjust a window size within said electro-optical sensor.
