Abstract:
A navigation device obtains real-time coordinates of an image for positioning. Data of the image are then transferred by a terminal to be analyzed. A route is thus obtained for navigation between position of the image and position of the terminal. The navigation device is able to navigate without a pre-installed map; but by using a route data from the Internet.

Description:
FIELD OF THE INVENTION 
       [0001]    The present invention relates to navigation; more particularly, relates to obtaining coordinates of an image for positioning to be transferred to a data providing unit by a terminal to be analyzed to obtain a route for navigation between position of the image and position of the terminal. 
       DESCRIPTION OF THE RELATED ARTS 
       [0002]    A general mobile device, such as a notebook, a PDA, a mobile phone, etc., is integrated with devices for communication, photography, navigation, data mining and Internet surfing so that multiple utilization are possible to a user with the mobile device. 
         [0003]    Although data transferring, photographing, map navigating, Internet surfing, etc. are possible for the user with the mobile device, only one function among them can be used at a time. A map navigation in a general mobile device is done only in its own map database which requires update after a period of time of use and is not so convenient. Additionally, when a photo is taken by the mobile device, only date and time are recorded as references; but not related data for the user to approach the position of the photo with navigation information. Hence, the prior arts do not fulfill users&#39; requests on actual use. 
       SUMMARY OF THE INVENTION 
       [0004]    The main purpose of the present invention is to obtain real-time coordinates of an image for positioning; then to transfer data of the image to a data providing unit by a terminal to be analyzed to obtain a route for navigation between position of the image data and position of the terminal. 
         [0005]    To achieve the above purpose, the present invention is an image navigation device, comprising an image shooting device, where the image shooting device comprises a lens unit, a processing unit, a positioning unit and a storage unit to acquire and position coordinates of an image data; a terminal, where the terminal comprises a receiving unit, a first connection unit and a display unit to receive and transfer the image data; and a data providing unit, where the data providing unit connects to the terminal to provide route data between position of the image data and position of the terminal. Accordingly, a novel image navigation device is obtained.

     DESCRIPTION OF THE PREFERRED EMBODIMENT 
       [0012]    The following description of the preferred embodiment is provided to understand the features and the structures of the present invention. 
         [0013]    Please refer to  FIG. 1  to  FIG. 3 , which are a perspective view, a main block view and a detail black view showing a preferred embodiment according to the present invention. As shown in the figure, the present invention is an image navigation device comprising an image shooting device  1 , a terminal  2  and a data providing unit  3 , where position information of an image shot by the image shooting device  1  is obtained at a real time; data of the image is transferred by the terminal  2  to the data providing unit  3  to be analyzed; and a route between position of the image data and position of the terminal  2  is thus obtained for a navigation. 
         [0014]    The image shooting device  1  comprises a lens unit  11 ; a processing unit  12  connected with the lens unit  11  a positioning unit  13  connected with the processing unit  12 ; and a storage unit  14  connected with the processing unit  12 , where the positioning unit  13  is a global positioning system (GPS) to provide coordinates of longitude, latitude and height for the image data  15 ; and the storage unit stores data of the image data, comprising a date, a time, and the coordinates of longitude, latitude and height for the image data. Thus, a real-time coordinates of the storage unit  14  is acquired and positioned; and a user&#39;s position is also known. The user can also trace a route when activating the positioning unit; and output a route file to be recorded. 
         [0015]    The terminal  2  is a computer, a PDA or a mobile phone; the terminal  2  comprises a receiving unit  21 , a first connection unit  22  and a display unit  23 ; and the terminal  2  receives and transfers the image data  15  in the image shooting device  1 . 
         [0016]    The data providing unit  3  is connected with the terminal  2 ; the data providing unit  3  provides data of a route between position of the image data and position of the terminal  2 ; and the data providing unit  3  comprises a communication unit  31 , being connected with the first connection unit  22  of the terminal  2 , a server unit  32 , authenticating the terminal  2 , and a navigation database  34 , providing the image data  15  by connecting to the server unit  32  through the second connection unit  33 . Thus, a novel image navigation device is obtained with the above structure. 
         [0017]    Please refer to  FIG. 4  and  FIG. 5 , which are a perspective view and a block view of a state of use. As shown in the figures, when using the present invention, a lens unit  11  of an image shooting device  1  shoots an image. When the image shooting device  1  shoots the image, a time, a date and coordinates of longitude, latitude and height for the image are obtained by a positioning unit  13  to be stored as an image data  15  in a storage unit  14 . Then the image data  15  is transferred through an email, a web page, a marketing media (e.g. CD-rom), an instant mess aging software (e.g. MSN), a memory card, etc. to be received by a terminal  2  from a receiving unit  21 . When a position information of the image data  15  is used to find a path between position of the image data  15  and position of the terminal  2 , a first connection unit  22  of the terminal  2  is connected with a communication unit  31  of a data providing unit  3 ; after passing an authentication of a server unit  32 , the image data  15  is transferred to a navigation database  34  through a second connection unit  33 ; a real-time position of the terminal  2  is obtained by an IP address unit  35 , a manual input unit  36  and a package unit  37 ; and the coordinates of longitude, latitude and height for the image data  15  are analyzed to find route data  38  between the position of the image data and the position of the terminal  2 . The route data  38  is transferred to the terminal  2  to be received by the connection unit  22  and displayed on the display unit  23  for the user to approach the position of the image data  15  with the route data  38 . In short, the position of the image data  15  is definitely and accurately obtained on shooting an image of the image data  15 . The image shot by the image shooting device  1  is then transformed into the image data  15  having position information, positioning data or route data. And the image data  15  is analyzed through the data providing unit  3  to obtain the route data  38  for the navigation with the image data  15 . Alternatively, the functions of the data providing unit  3  can be integrated into the terminal  2  for analyzing navigation route without using the Internet. 
         [0018]    To sum up, the present invention is an image navigation device, where coordinates of an image are obtained for positioning; and data of the image are transferred to a data providing unit by a terminal to be analyzed to obtain a route for navigation between position of the image data and position of the terminal.

Therefore, simple modifications or variations belonging to the equivalent of the scope of the claims and the instructions disclosed herein for a patent are all within the scope of the present invention.
