US Patent 7532910 Multifunctional mobile phone with automatic cannot answer messaging

A multifunctional mobile phone includes a control system, a keypad (3) with a switch (31) comprising a “self-take pictures” position, a camera module (4) with an image sensor and a “self-take pictures” state, a timer connected to the camera module, and a housing (2) for receiving the control system, the keypad, the camera module and the timer therein. The switch, the camera module and the timer are connected to and controlled by the control system. When the owner of the multifunctional mobile phone cannot answer an incoming call, the camera module takes a picture automatically and sends it to the caller together with a word message after a prearranged time. Then the caller will hang up the phone. Thus the multifunctional mobile phone will not make endless noise.
