The touch screen 151 of the mobile terminal displays the first image (S410). The touch screen 151 receives a first user touch operation on the first image (S420). In response to the first user touch operation being input, the camera 151 is driven and a second image is received from the outside through the camera 151 (S430). The touch screen 151 displays the second image in a specific area among the areas where the first image is displayed (S440).

On the other hand, although not shown in the flow chart of Figure 4, it may include additional steps.

The touch screen 151 receives a second user touch operation on the displayed second image and stores the first image in the memory 160 in association with the second image according to the second user touch operation.

5 is a view illustrating a transparent display method in accordance with the present invention.

As used herein, the term 'transparent display' refers to a method in which an external image through the camera 121 is immediately displayed on all or a part of the touch screen 151 of the mobile terminal. Therefore, when performing the transparent display method, since the user of the mobile terminal can directly view an external image through the touch screen 151, the mobile terminal 100 can obtain the same effect as the transparent.

FIG. 5A illustrates that the first image is displayed in the specific area 510 when performing a specific operation (phonebook function) of the mobile terminal.

FIG. 5 (b) shows the transparent display function of the present invention operating to display the replacement of the first image with the second image.

In FIG. 5A, the first image previously stored in the mobile terminal is displayed in the phone book. In FIG. 5B, when there is a touch operation with respect to the first image, a transparent display function is performed so that an external image, that is, a second image through the camera 151 is replaced and displayed on the first image display area 510. Shows that.

As a result, since the second image, which is the external image through the camera 151, is immediately visible in the area where the first image stored in the mobile terminal is displayed, it has an effect of appearing to be transparent.

Meanwhile, when the second image is displayed in the first image display area 151 using the transparent display method, the image of the corresponding phone book may be replaced with the second image instead of the first image and stored. Accordingly, it is not necessary to delete an existing image from the corresponding phone book and select a camera function to take an external image and store it in the telephone book. With the transparent display method, the external image can be loaded and saved at the same place where the external image is to be edited.

6 illustrates touch operations for selecting a first image and performing a transparent display function according to the present invention.

6 (a) to 6 (c) display the same first image. As shown in FIG. 5A, a first image representing the other party of the phone book is displayed on the touch screen 151.

6A illustrates a first embodiment of a user touch operation of selecting a first image.

FIG. 6A illustrates receiving a touch operation on a first image for a predetermined time or more from a user. Although the prescribed time is shown in the figure as 2 seconds, this is illustrative and not limited thereto. Depending on the user's or manufacturer's choice, the specified time may be variously set. When there is a user touch operation for a predetermined time or more, the controller 180 determines that the first image is selected.

6B illustrates a second embodiment of a user touch operation of selecting a first image.

In FIG. 6B, it is shown that a touch operation for forming a specific closed curve 610 is received. When the touch motion trajectory from the user forms a closed curve and a part or all of the first image is included in the closed curve area, the controller 180 determines that the first image 510 included in the closed curve 610 is selected. .

6C illustrates a third embodiment of a user touch operation of selecting a first image.

In FIG. 6C, when the first image is touched by the user, a selection menu 620 associated with the first image is displayed. The configuration of the selection menu may include various functions. For example, in the drawing, the corresponding image deletion and transparent display functions are displayed in the configuration of the selection menu. When the transparent display function is selected, the controller 180 determines that the first image is selected.

When there is a user touch operation for selecting the first image as described above, the controller 180 determines that the first image is selected. In addition, the controller 180 controls the camera 121 and the touch screen 151 to perform a transparent display function in response to an input of a user touch operation.

Accordingly, when there is a user touch operation on the first image, the transparent display function is activated by displaying a second image, which is an external image through the camera 121, on a part or all of the area where the first image is displayed. .

The above-described user touch operation is exemplary and may be included in the user touch operation in the case of selecting an image. For example, a method of touching the first image several times and a selection method using a key button may be included in the user touch operation.

FIG. 10A illustrates a method of displaying a second image inside an object and displaying a first image outside the object when a specific object exists in the first image.

FIG. 10A (a) is a diagram of displaying a first image that is previously stored and displayed in the mobile terminal 100. Referring to FIG.

FIG. 10A (b) is a diagram of displaying a second image through the camera 121. FIG. When there is a user touch operation on the first image, the camera 121 is operated to show the second image received from the outside of the terminal.

FIG. 10A (c) is a diagram illustrating editing and displaying a first image using a second image.

A person corresponding to an object exists in the first image illustrated in (a) of FIG. 10A. Therefore, in the present exemplary embodiment, the transparent display function is operated inside the object of the first image to display the second image, which is the external image, and the background of the existing first image is displayed as it is outside the object. Accordingly, in (c) of FIG. 10A, the background of the first image of (a) of FIG. 10A is displayed on the outside of the object as it is, and the second image of (b) of FIG. 10A is displayed inside of the object.

According to the user's selection, the first image may be edited and stored or displayed in various ways using the second image in this manner.

FIG. 10B illustrates a method of displaying a first image inside an object and displaying a second image outside the object when a specific object exists in the first image in a case opposite to that of FIG. 10A.

FIG. 10B (a) illustrates a display of a first image that is previously stored and displayed in the mobile terminal 100.

10B (b) is a diagram of displaying a second image through the camera 121. When there is a user touch operation on the first image, the camera 121 is operated to show the second image received from the outside of the terminal.

FIG. 10B (c) is a diagram illustrating editing and displaying a first image using a second image.

A person corresponding to an object exists in the first image illustrated in (c) of FIG. 10B. Therefore, in the present exemplary embodiment, the transparent display function is operated outside the object of the first image to display the second image, which is the external image, and inside the object so that the object of the existing first image is displayed as it is. Accordingly, in (c) of FIG. 10B, the object of the first image of (a) of FIG. 10B is displayed as it is inside the object, and the second image of (b) of FIG. 10B is displayed outside of the object.

Additionally, when there is a prescribed user touch operation on the image, the edited first image using the second image may be stored.

Such a first image editing method is useful when one wants to use only one of a background or an object in an existing first image and display the remaining area as an external image.

10C illustrates another embodiment of editing and displaying a first image by using a second image.

(A) of FIG. 10C is a diagram for displaying a first image that is previously stored and displayed in the mobile terminal 100.

FIG. 10C (b) illustrates a user touch operation on the first image.

In the drawing, a specific region 1010 is selected instead of the entire first image by a user touch operation on the first image. The controller 180 recognizes the user touch operation as the user touch operation on the first image and controls the transparent display function to operate.

The transparent display function is performed to display a second image, which is an external image through the camera 121, only in a region corresponding to the specific region 1010.

FIG. 10C illustrates that the second image is displayed only in the specific area 1010 designated by the user's touch operation. Accordingly, the first image is displayed as it is in the region except for the specific region 1010 among the first images, and the external image through the camera 121 is displayed in the specific region 1010.

On the other hand, the reverse case is also possible by setting. For example, if there is a user touch action on the first image and the user touch action forms a specific closed curve as described above, the first image is displayed in the closed curve as it is and the second image is an external image outside the closed curve. Can be displayed.

In this manner, the first image may be displayed using the second image, and the edited first image may be stored when there is an additional touch action of the user.

There may be various editing methods for the second image through the transparent display method.

For example, an oily paper effect can be used. When oil paper is placed on a book with letters or drawings, only the outline of the letters or pictures is reflected. This embodiment functions similarly to this effect. When an object exists in an image through the second image, the object of the second image is edited and stored as a new image. In the case of using such a function, various effects are possible because the image can be stored as an object of the corresponding image as well as the actual image.

In addition, in the above description, the second image through the camera 121 is displayed on the touch screen 151 with the same size as actually seen. However, it may include a function of enlarging / reducing the second image. Accordingly, there is an effect of editing and storing the second image and the first image more accurately and easily than when editing the second image and the first image.

In another embodiment of the present invention, a third image through another camera 121 'of the mobile terminal may be used.

Referring to FIG. 2A, the mobile terminal may include another camera 121 'inside the terminal. This is a separate camera from the camera 121 outside the terminal.
