In the preview image, it is possible to distinguish a portrait image, which is a character image, and a background image, which is a background image, and delete a background image adjacent to the portrait image, and then enlarge the portrait image to the deleted area to display an enlarged portrait image have. By enlarging and displaying the portrait image of the specific person selected as described above, the user can confirm the selected person.

Meanwhile, the controller 180 determines whether a person information display command is input (S460). In the touch screen 400, a service provided in the person mode may be indicated by an icon. When the user desires to receive the person information, the user can input the person information display command by selecting the information icon displayed on the touch screen 400.

Then, the control unit 180 performs the person recognition based on the face among the selected portrait images (S465). Specifically, the control unit 180 extracts feature points such as eyes, nose, and mouth from the face of the selected portrait image. The degree of similarity between the face of the selected person image and the face of the person image stored in the person database is calculated using the extracted minutiae, and based on the calculated similarity value, the person in the preview image is identified with the specific person included in the person database To recognize the person.

The person database may be stored in the memory 160 of the portable terminal. However, if the person database is not stored in the memory 160 of the portable terminal, the controller 180 can access the external device of the person database through the wireless communication unit 110 and use the person database of the external device . It is preferable that the person image and the person information are stored in a matching manner in the person database.

Here, the person information is information characterizing the person, and preferably includes the name of a person, a telephone number, SNS (Social Network Site) site information, and the like. Particularly, a phonebook database built in a portable terminal can be utilized as a character database.

The control unit 180 acquires the person information of the recognized person from the person database (S470), and displays the obtained person information in one area of the preview image (S475). In displaying the person information, it is preferable to display the person information in an area adjacent to the area where the person is displayed, and a notification indicator indicating that the person information of the specific person is displayed can also be displayed.

It is determined whether a command to save a portrait image corresponding to a specific person in the preview image is input. The user can input a person image storage command by selecting an area in which a specific person is displayed in the preview image and then selecting an area where the storage icon is displayed.

If it is determined that the person image storage command is input, the controller 180 generates a still image corresponding to the separated person image and stores the same in a person database or a still image file.

In particular, when a portrait image is stored in a person database, the controller 180 stores a person image (hereinafter, referred to as an 'existing person image') representing the same person as the person to be stored in the person database, 180 may update the portrait image, that is, delete the existing portrait image, store the current portrait image in the portrait database, or add the portrait image to the existing portrait image, and store the portrait image in the portrait database. In this case, the control unit 180 may generate notification information indicating that the person image of the same person is stored in the person database, and display the notification information on the touch screen 400. If the person image of the same person is not stored in the person database, the control unit 180 displays a screen corresponding to the person database. The above-mentioned screen is composed of a region in which a portrait image is displayed and an area in which person information can be input.

5 is a flowchart illustrating a method of adding a portrait image to a preview image according to an embodiment of the present invention.

As shown in FIG. 5, the control unit 180 determines whether a person image addition command is input (S510). When the user wants to add a specific character to the preview image, the user can input the character image addition command by selecting the additional icon.

If it is determined that a person image addition command has been input (S510-Y), the control unit 180 reads out at least one person image (hereinafter, referred to as a candidate person image) as an addition target stored in the person database, Or displays the candidate portrait image in one area of the touch screen 400 in which the preview image is displayed (S520). If the candidate character image can not be displayed on one screen, the control unit 180 displays some of the read candidate character images on the touch screen 400 and displays notification information indicating that there are more candidate character images that are not displayed Or can be displayed using a progress bar or an arrow.

When a command to select an additional portrait image among the candidate portrait images is inputted through the user input unit (S530-Y), the controller 180 displays the selected portrait image in one area of the preview image in the form of a pop-up window at operation S540.

When the dragging after the multi-touch is input (S550-Y), the controller 180 changes the size of the portrait image corresponding to the multitouch and dragging (S560). Specifically, when a user touches an area in which a character image is displayed with at least two fingers, at least two touch points are generated. When the user drags the touch points in the direction in which the touch points move away from each other, the controller 180 enlarges the size of the portrait image corresponding to the dragged distance. When the touch points are dragged in the direction of approaching each other after being multi-touched, the controller 180 reduces the size of the portrait image corresponding to the dragged distance.

When the single-touch post-drag is input (S570-Y), the controller 180 changes the position of the portrait image corresponding to the drag after the single-touch operation (S580). Specifically, one touch point is created by touching an area in which a specific character image is displayed with one finger. When the user finishes the touch after dragging the touch point, the control unit 180 moves and displays the portrait image in the area where the touch is terminated.

When a shooting command is input (S590), the controller 180 generates one still image in which the preview image and the portrait image are combined, and stores the generated still image in the memory 160 (S595). Preferably, the memory is a person database.

Then, a still image corresponding to the preview image is generated (S620). That is, the resolution of the preview image is changed to the resolution of the still image, and the still image is generated by adjusting the preview image according to the changed resolution.

In addition, the controller 180 performs character recognition on the selected portrait image (S630). Specifically, the control unit 180 detects the face of the selected portrait image, and extracts the feature points of eyes, nose, mouth, etc. from the detected face. The similarity degree between the face of the selected portrait image and the face stored in the character database is calculated by using the extracted feature points, and based on the calculated similarity value, the person in the preview image is identified by the same person as the specific character included in the character database .

Then, the control unit 180 acquires information on the SNS (Social Network Service) site to which the person selected from the person database belongs based on the person recognition result (S640). The information about the SNS site is preferably an address for the SNS site.

The order of S620 for generating a still image and S630 and S640 for acquiring SNS site information may be changed.

The control unit 180 accesses the SNS site using the SNS site information, and uploads the still image to the SNS site (S650). In addition, when the preview image is uploaded, the control unit 180 may display the web page corresponding to the SNS site on the touch screen 400 by driving the web browser, and may display the image uploading process. Here, SNS is a site that enables social networks, including blogs, cyworld, YouTube, Twitter and so on.
