That is, the present invention can provide different storage and editing methods according to the purpose of captured and photographed images, and can automatically provide related keyword information such as location, contact, and URL through tag information of an image.

Meanwhile, in the storing step (S430), the image is classified and stored according to the type of the person or object included in the image.

For example, in the case of a portrait, tag information including position, time, and person information is generated. In the case of a food photograph, information such as position, time, and restaurant information, It is possible to generate tag information including position, time information, and the like when the image is a photograph.

In the case of a user's own portrait, it can be classified into an album, an other person, an event album in the case of a landscape photograph, and a food album in the case of a food photograph, and stored in another storage area.

In addition, a plurality of images can be grouped according to the type of person or object included in the image, and tag information can be collectively generated.

According to another aspect of the present invention, there is provided a method of operating a portable terminal, the method further comprising extracting text included in the image data, and storing text included in the image data .

The extracted text can be used not only for the generation of the tag information but also for various operations such as editing by storing it separately in a notepad or a clipboard.

5 to 10, the user can photograph the person 510 and the scenery 520 and 530 using the portable terminal 100. In this case, the control unit 180 can classify the image as a portrait or an audition since there is a person 611 included in the photographed image 610.

Accordingly, the controller 180 can generate tag information including photographing time information, a phone number of the portable terminal, location information, and the like.

When the user inputs an entry corresponding to the tag information view command while the image is displayed, the tag information can be displayed. For example, if the user pinches-in the original image and the user pinches-in the image, the metadata tag tag 720 may be displayed in the lower region of the reduced image 710 have.

Herein, the pinch-in is a drag input in which a plurality of touch input points are spaced apart by a distance, and the display unit 151 is multi-touched with a touch input tool such as two fingers or a stylus pen, May be an input by an operation of narrowing down the input signal.
