Abstract

A combination mobile communication device and camera that combines a hand-held mobile terminal and camera in the same physical package is described herein. The combination mobile communication device and camera uses one or more multi-function controls to control communication functions and camera functions. A user selectively places the device in either a communication mode for engaging in wireless communication with a remote device, or in a camera mode for capturing and/or viewing images. A multi-function control disposed on a side of the combination mobile communication device and camera comprises a multi-directional button that controls a communication function, such as the volume of the speaker, when the device is in a communication mode. When the device is in a camera mode, the multi-function control is used as a zoom control.
