An endoscopic camera system includes zooming capability to non-mechanically enlarge images of internal features of a body during an endoscopic procedure. The system includes a scope for insertion into the body, a camera head coupled to the scope, and a camera control unit coupled to the camera head. Video image data of internal features of the body are acquired through the scope by the camera head and transmitted to the camera control unit, which generates video images for display on a monitor. The camera control unit includes zoom circuitry for digitally zooming the video images in real-time. Operation of the zoom circuitry may be controlled by manual input or by voice commands. Voice commands may be used to set and recall preset zoom views.
