Patent ID: 7903147

Claim:
A communication device comprising: a camera; a camera function processing module that controls the camera; a mobile communication function processing module that performs a mobile communication function with an another communication device; a register that stores camera existence data indicating that the communication device includes a built-in camera; a local area communication interface unit that transmits the camera existence data by wireless in response to an external detection request signal received by wireless; and a power control unit that intercepts power supplied to the camera function processing module in response to a power interception signal from a radio frequency identification integrated circuit (RFID IC) tag, wherein the local area communication interface unit generates an enable setting signal in response to an external enable-setting request signal received by wireless, wherein the camera function processing module disables the camera function when the enable setting signal has a first logic state, and the camera function processing module activates the camera function when the enable setting signal has a second logic state, and wherein the camera outputs image signals for displaying a specific image pattern when the enable setting signal has the first logic state.
