An electronic camera includes an imager, having an imaging surface capturing a scene, which repeatedly outputs a scene image. In a first embodiment a procedure for finding an optimal path between an originating network node and a destination network node is integrated in the handoff procedure. An outer wall includes an essentially pore-free cast metal layer that is at least one of positively engaged with the dense core surface layer and surrounding the inner core, and metallically joined to the dense core surface layer and surrounding the inner core. When the touch screen detects a touch signal in display blocks and the touch signal is moved toward the coordinate axis direction for a first displacement, the graphic menu bar displayed on the touch screen is moved toward a direction opposite to the coordinate axis direction for a second displacement, and the second displacement is equal to the product of the first displacement and N.
