Abstract

A hand-held device having positioning and photographing functions and geographical positioning methods thereof is provided. The hand-held device includes a photographing module, a positioning module, a database and a processor. The photographing module photographs environment of a shooting place to form a digital picture. The positioning module accesses a positioning data of the shooting place. The processor matches the positioning data of the shooting place with a geographical positioning condition when the digital picture is obtained, so as to get a target geographical area data corresponding to the shooting place, from all geographical area data. The target geographical area data is displayed on the digital picture corresponding to the shooting place and the geographical positioning condition is an area center data of every geographical area data or plural boundary pointers which include boundary coordinates of every geographical area data.

Claims

1. A hand-held device having positioning and photographing functions, the hand-held device comprising:

a photographing module which is used to photograph environment of a shooting place to form a digital picture;

a positioning module which is used to access positioning data of the shooting place;

a database which stores plural geographical area data and at least one geographical positioning condition; and

a processor which couples the photographing module, the positioning module and the database;

wherein while obtaining the digital picture, the processor matches the positioning data of the shooting place with the geographical positioning condition to access a target geographical area data corresponding to the shooting place from the geographical area data, thereby displaying the target geographical area data on the digital picture corresponding to the shooting place.

2. The hand-held device having positioning and photographing functions according to claim 1, wherein the at least one geographical positioning condition includes area center data of every geographical area data, and the processor compares the positioning data of the shooting place with plural area center data to find out the target geographical area data, and an Euclidean distance between the area center data of the target geographical area data and the positioning data of the shooting place is the smallest.

3. The hand-held device having positioning and photographing functions according to claim 1, wherein the at least one geographical positioning condition includes plural boundary pointers which contain boundary coordinates of every geographical area data, and the processor finds out plural target boundary pointers of the positioning data that are close to the shooting place from the boundary pointers and then matches the target boundary pointers with the boundary pointers so as to find out the target geographical area data of the target boundary pointers.

4. The hand-held device having positioning and photographing functions according to claim 1, further including a storage medium which couples with the processor;

after marking the target geographical area data on the digital picture, the processor compressing the digital picture as an image file and storing the image file in the storage medium.

5. The hand-held device having positioning and photographing functions according to claim 1, wherein the target geographical area data is an address, and the address is selected from a group consisting of a country, a state, a province, a metropolitan, a territory, a shire, a county, a city, a township, a village, a road, a street, a section, a lane, an alley and a number.

6. The hand-held device having positioning and photographing functions according to claim 1, wherein the target geographical area data is a geographical name.

7. The hand-held device having positioning and photographing functions according to claim 1, wherein the database includes plural country codes corresponding to the geographical area data, and the target geographical area data includes one target country code of the shooting place.

8. The hand-held device having positioning and photographing functions according to claim 1, wherein the database includes plural international phone numbers corresponding to the geographical area data, and the target geographical area data includes one international phone number of the shooting place.

9. The hand-held device having positioning and photographing functions according to claim 1, wherein the processor displays time on the digital picture time when the digital picture is captured.

10. A geographical positioning method comprising following steps:

obtaining positioning data;

comparing the positioning data with area center data of every first geographical area data in plural first geographical area data;

obtaining target geographical area data based on a comparison result, wherein an Euclidean distance between the area center data of the target geographical area data and the positioning data is the smallest;

determining whether the target geographical area data includes plural second geographical area data;

taking the second geographical area data as the first geographical area data and returning to the step of comparing the positioning data with the area center data of every first geographical area data in plural first geographical area data when the target geographical area data including plural second geographical area data; and

storing the target geographical area data when the target geographical area data not including plural second geographical area data.

11. The geographical positioning method according to claim 10, wherein the first geographical area data is country area data, and the second geographical area data is province area data, state area data, metropolitan area data, territory area data or shire area data.

12. The geographical positioning method according to claim 10, wherein the first geographical area data is province area data, state area data, metropolitan area data, territory area data or shire area data, and the second geographical area data is county area data or city area data.

13. The geographical positioning method according to claim 10, wherein the first geographical area data is county area data or city area data, and the second geographical area data is county area data or city area data.

14. The geographical positioning method according to claim 10, wherein the first geographical area data is county area data or city area data, and the second geographical area data is landscape data.

15. A geographical positioning method comprising following steps:

obtaining positioning data;

obtaining plural boundary pointers of plural first geographical area data;

searching along plural different directions by taking the positioning data as a start point to find out target boundary pointers that are closest to the positioning data on each different direction;

comparing the target boundary pointers with the boundary pointers to access target geographical area data from the first geographical area data;

determining whether the target geographical area data includes plural second geographical area data;

taking the second geographical area data as the first geographical area data, and returning to the step of obtaining plural boundary pointers of plural first geographical area data when the target geographical area data including plural second geographical area data being taken as; and

storing the target geographical area data when the target geographical area data not including plural second geographical area data.

16. The geographical positioning method according to claim 15, wherein the first geographical area data is country area data, and the second geographical area data is province area data, state area data, metropolitan area data, territory area data or shire area data.

17. The geographical positioning method according to claim 15, wherein the first geographical area data is province area data, state area data, metropolitan area data, territory area data or shire area data, and the second geographical area data is county area data or city area data.

18. The geographical positioning method according to claim 15, wherein the first geographical area data is county area data or city area data, and the second geographical area data is township area data.

19. The geographical positioning method according to claim 15, wherein the first geographical area data is country area data, and the second geographical area data is county area data or city area data.

20. The geographical positioning method according to claim 15, wherein the first geographical area data is county area data or city area data, and the second geographical area data is landscape data.
