Next, please refer to FIG. 4 for a flow chart of steps of the navigation image conversion process of the present invention.

First, step 401 is performed: the map image is captured according to the sampling rate to obtain a plurality of captured images.

To convert the electronic map into a continuous navigation image, first, the capturing unit 11 draws a plurality of captured images according to the sampling rate along the planning path when capturing the map image. The sampling rate can be adjusted according to the demand. For example, the sampling rate can be set to a fixed constant, and the capturing unit 11 extracts the captured image according to a fixed frequency. Or you can adjust the length of the path. For example, when the path distance is long, a smaller sampling rate value is utilized to reduce the amount of captured pictures. When the path distance is short, a larger sampling rate value is utilized to increase the amount of captured image. It is also possible to increase the sampling rate on special sections to alert the user. In this way, the first captured image A1, the second captured image A2, and the third captured image A3 as shown in FIGS. 3B to 3D can be obtained.

Step 402: Analyze the captured image of the complex number to fill in the weight value.

Then, the captured image of the cut complex number is analyzed by the capturing unit 11 or the editor 12 to fill in the weight value. The capturing unit 11 can analyze the captured images according to the scenic spots, intersections, special road sections or the editing section of the user using the editor 12, and fill in different weight values according to different situations. Taking the captured pictures shown in FIGS. 3B to 3D as an example, the first captured picture A1 and the third captured picture A3 of FIGS. 3B and 3D are captured images of the intersection, so the weight value is set to 2. The second drawing picture A2 of Fig. 3C is a picture taken by a straight road, so its weight value is set to 1. Similarly, the user can also increase the weight value by using the edited section of the editor 12.

Step 403: Select a selected picture of the plural according to the weight value.

In order to reduce the size of the navigation image, the image integration unit 24 selects a plurality of selected pictures by using different weight values previously filled in by the capture unit 11 and/or the editor 12. Therefore, the first captured picture A1 and the third captured picture A3 whose weight value is set to 2 are preferentially selected, and the second captured picture A2 whose weight value is set to 1 is selected within the permitted range of the navigation image size.

Then, step 404 is performed: matching the indication text to generate a subtitle file.

The subtitle creating unit 23 calculates the time when a certain selected picture appears and ends, and creates a subtitle file according to the corresponding indication text and voice file. For example, the first indication text B1 is created as a subtitle file at the time point when the first captured picture A1 appears and ends, and the second indication text B2 is created into a subtitle file at the time point when the third captured picture A3 appears and ends.

Finally, step 405 is performed to integrate the plurality of selected pictures, voice files and subtitle files to become navigation images.

Finally, the image integration unit 24 can integrate a plurality of selected pictures, voice files and subtitle files to form a navigation image for the user to easily view.

It should be noted here that the method for downloading the navigation map of the present invention is not limited to the above-described sequence of steps, and the order of the above steps may be changed as long as the object of the present invention can be achieved.
