Should be interpreted.

The first terminal 100 and the second terminal 200 of the present invention is preferably provided with a photographing equipment, such as a camera that can photograph an external object or scene. In addition, the first terminal 100 and the second terminal 200 has a communication interface for data transmission and reception through the network 300.

The first terminal 100 receives an image captured by the second terminal 200 through the network 300 and expresses the image captured by the second terminal 200 on the display device in the form of a free view. In this case, the second terminal 200 may be one or more terminals, and the first terminal 100 may express the image photographed by the second terminal 200 and the image photographed by the second terminal 200 together on the display device. In this way, an image captured at a location separated from one object or scene may be simultaneously checked by one terminal. In this case, the first terminal 100 may change and display the arrangement of the images to be displayed on the display device according to a user input through the input device. For example, the arrangement may be changed by touching and dragging a specific image in a display liquid crystal formed of a touch screen to move the position. In addition, according to a setting of the first terminal 100 or a user input, a specific image may be displayed larger than other images.

While displaying the image captured by the first terminal 100 and the image captured by the second terminal 200 in the form of a preview, for example, the plurality of images displayed by the input device of the first terminal 100 are displayed. When the selection input for the specific image is received, only the specific image may be represented on the screen of the display device. In addition, while the first terminal 100 displays only a specific image, only the changed image may be displayed on the screen of the display apparatus according to a user input through the input apparatus. For example, when the first terminal touches an image that was displayed alone on a display liquid crystal formed of a touch screen and receives a flick input signal as if it slides up, down, left, or right, the first terminal changes to another image and changes the image. Only the display liquid crystal can be expressed.
