     DETAILED DESCRIPTION OF THE INVENTION 
       [0027]    The features and practice of the present invention will be illustrated below in detail through preferred embodiments with reference to the accompanying drawings. 
         [0028]    Referring to  FIG. 1 , it is a schematic diagram of a camera phone connecting with a receiving end according to an exemplary embodiment of the present invention. 
         [0029]    A camera phone  100  includes an addressing module  101 , a photographing module  102 , and a real-time transmission module  103 . The addressing module  101  stores at least a network address of a receiving end. In this exemplary embodiment, the addressing module  101  has stored the network addresses of a server  201  and a computer  202 . Each of the server  201  and the computer  202  includes a memory module  203 , in which at least a memory space (not shown in  FIG. 1 ) is divided from the memory module  203 , and each memory space is corresponding to a number of the camera phone  100 . 
         [0030]    The photographing module  102  is used for a user to photograph a sight  300  in his location, so as to form a media data, which has been stored temporarily. The real-time transmission module  103  obtains the media data and reads the network addresses of the server  201  and the computer  202 , which are stored in the addressing module  101 , so as to transmit the media data to the server  201  and the computer  202  of the receiving end according to the network addresses. The server  201  and the computer  202  have known the corresponding number of the camera phone  100  through the received media data, so as to store the media data in the memory space of the memory module  203  corresponding to the number. 
         [0031]    Furthermore, the camera phone  100  includes a control interface for users to add, delete, or change network addresses, amounts, or names of receiving ends stored in the addressing module  101 . 
         [0032]      FIG. 2  is a first flow chart of a real-time addressing image transmission method of a camera phone according to an exemplary embodiment of the present invention. Referring to  FIG. 1  and  FIG. 2  in the same time, a real-time addressing image transmission method of a camera phone includes steps as following: 
         [0033]    A sight is photographed to form a media data (Step  201 ). When a user utilizes the camera phone  100  to photograph a sight  300 , a media data corresponding to a lens of the camera phone  100  is formed by the photographing module  102 . Therein, the media data could be a picture or an image. 
         [0034]    At least a network address of a receiving end is judged whether is stored or not (Step  202 ). After the real-time transmission module  103  obtains the media data, the addressing module  101  is read to judge whether any network address is stored or not. 
         [0035]    If the network address is stored, the media data is transmitted to the receiving end (Step  203 ). It includes transmission modes as following: (1) A multimedia messaging technology is utilized to transmit the media data to the receiving end. (2) A network connecting mode is utilized to upload the media data to the computer  202  or the server  201  corresponding to the network address. The media data is transmitted according to a user datagram protocol (UDP) or a transmission control protocol (TCP). (3) If the media data is a continuing image, a streaming media technology is utilized to transmit the image to the receiving end. Then, the media data is obtained by the server  201  and the computer  202 , and is stored in the memory space of the memory module  203  corresponding to the number of the camera phone  100 . 
         [0036]    If the network address is not stored, the media data is stored (Step  204 ) in a memory unit  104  of the camera phone  100 . 
         [0037]    Referring to  FIG. 3 , it is a second flow chart of a real-time addressing image transmission method of a camera phone according to an exemplary embodiment of the present invention. Compared to the first flow shown in  FIG. 2 , the difference of the second flow is that a query message about storing the media data is outputted (Step  205 ) when the real-time transmission module  103  judges that there is not any network addresses of the receiving end has been stored in the addressing module  101 , so as to query the user whether to store the media data in the camera phone or not, and also inform the user how to input a command. 
         [0038]    Then, the real-time transmission module  103  judges whether a storage command is obtained or not (Step  206 ). If the storage command is obtained, the media data is stored (Step  204 ). If the storage command is not obtained, the media data is deleted (Step  207 ), so as to avoid occupying a memory space of the memory unit  104 . The step is used for the user to initially choice the media data, which is needed, before the user stores the media data in the camera phone  100 . 
         [0039]    Referring to  FIG. 4 , it is a third flow chart of a real-time addressing image transmission method of a camera phone according to an exemplary embodiment of the present invention. Compared to the second flow shown in  FIG. 3 , the difference of the third flow is that a query message about transmitting the media data in real-time is outputted (Step  208 ) when the real-time transmission module  103  judges that there is at least a network addresses of the receiving end has been stored in the addressing module  101 , so as to query the user whether to transmit the media data in real-time or not, and also inform the user how to input a command. 
         [0040]    Then, the real-time transmission module  103  judges whether a transmission command is obtained or not (Step  209 ). If the transmission command is obtained, the media data is transmitted to the receiving end (Step  203 ). The user could decide whether the real-time transmission function is used or not according to the urgency of scenes to transmit the media data in real-time. 
         [0041]    If the real-time transmission module  103  has judged that the addressing module  101  does not store any network address of the receiving end, the real-time transmission module  103  does not obtain any transmission command (not obtaining in a specific time or the user inputting a control command of un-transmitting in real-time), or the media data has been transmitted in real-time, a query message about storing the media data is outputted (Step  205 ) through the real-time transmission module  103 , so as to query the user to store the media data in the camera phone or not, and also inform the user how to input a command. 
         [0042]    Then, the real-time transmission module  103  judges whether a storage command is obtained or not (Step  206 ). If the storage command is obtained, the media data is stored (Step  204 ) in the memory unit  104  of the camera phone  100 . If the storage command is not obtained (the user not inputting the storage command in a specific time or the user inputting a control command of un-storing the media data), the media data is deleted (Step  207 ) by the real-time transmission module  103 , so as to avoid occupying the memory space of the memory unit  104 . 
         [0043]    Referring to  FIG. 5 , it a schematic diagram of photographing a taxi before taking the taxi according to an exemplary embodiment of the present invention. The time is very short from a taxi  301  stopping to a user opening a car door and getting into the taxi  301 . The user could utilize the camera phone  100  to photograph an appearance, features, and a license plate of the taxi  301 , and utilize the real-time transmission module  101  to transmit the photographed media data to the computer  202  and server  201  in real-time for conserving an evidence of taking the taxi  301 . 
         [0044]    Referring to  FIG. 6 , it is a schematic diagram of photographing a scene of a traffic accident according to an exemplary embodiment of the present invention. The user could utilize the camera phone  100  to photograph a scene of a traffic accident to obtain a traffic accident picture  302 , and transmit the traffic accident picture  302  to the server  201  and the computer  202  in real-time, so as to conserve an evidence and prevent a troublemaker from escaping. 
         [0045]    Referring to  FIG. 7 , it is a schematic diagram of photographing a scene of a crime according to an exemplary embodiment of the present invention. The user could utilize the camera phone  100  to photograph an appearance, features, and criminal behavior of an active crime scene  303 , and transmit the pictures and images in real-time to the server  201  and the computer  202  for conserving an evidence effectively. Even if the camera phone  100  has been broken, the criminal process could be known through the pictures and the images, which are taken from the computer  202  and the server  201 . 
         [0046]    Referring to  FIG. 8 , it is a schematic diagram of photographing a scene of an activity according to an exemplary embodiment of the present invention.
