The alarm unit 153 may output a signal for notifying the occurrence of an event in a form other than the video signal or the audio signal, for example, vibration. The video signal or the audio signal may be output through the display unit 151 or the audio output module 152 so that they may be classified as a part of the alarm unit 153.

The haptic module 154 generates various tactile effects that the user can feel. A typical example of the haptic effect generated by the haptic module 154 is vibration. The intensity and pattern of the vibration generated by the hit module 154 can be controlled. For example, different vibrations may be synthesized and output or sequentially output.

As described above, the portable terminal according to the present invention includes at least two cameras to capture a 3D image. Further, the portable terminal according to the present invention may include a display unit capable of displaying 3D images.

As described above, the portable terminal according to the present invention may have a function of photographing a special image such as a 3D photographing function, a panoramic photographing function, and a high-resolution photographing function.

Generally, when two cameras are provided, one camera may be configured as a low pixel for video communication and the other as a high-resolution camera for general shooting.

However, the portable terminal according to the present invention can provide a 3D photographing function, a panoramic photographing function, and a high-resolution photographing function by using two cameras and photographing images taken by respective cameras.

2 illustrates a method of generating a 3D image and a method of generating a panoramic image. The method shown in FIG. 2 relates to a method for selectively generating a 3D image and a panorama image through a camera having two cameras, each of which is provided with a camera.

Specifically, FIG. 2 (a) shows a method of generating a 3D image, and FIG. 2 (b) shows a method of generating a panorama image.

First, with reference to Fig. 2 (a), a principle of photographing or displaying a 3D image will be discussed.

3D images that can be implemented on the display unit 151 of the portable terminal according to the present invention can be roughly divided into two categories. The criterion for this classification is whether or not different images are provided in both eyes. First, we describe the first 3D image category.

The first category is monoscopic in that the same image is provided in both eyes, which is advantageous in that it can be implemented as a general display unit. More specifically, the controller 180 arranges a polyhedron generated through one or more points, lines, faces, or a combination thereof on an imaginary three-dimensional space, and displays the image viewed at a specific time on the display unit 151 . Therefore, the substantial portion of such a 3D image can be referred to as a planar image.

The second category is a stereo scopic method in which different images are provided in both eyes. It is a method using a principle of feeling a three-dimensional feeling when a human is looking at an object with the naked eye. In other words, the two eyes of a person can see different planar images when they see the same object by the distance between them. These different planar images are transmitted to the brain through the retina, and the brain fuses them to feel the depth and reality of the 3D image. Therefore, binocular disparity due to the distance between the two eyes makes a sense of stereoscopic effect, and this binocular disparity becomes the most important element of the second category. This binocular disparity will be described in more detail with reference to Fig.

2 (a) is a conceptual diagram for explaining a method of generating a 3D image using the principle of binocular parallax. In this case, the first camera 121 can take a left-eye plane image of the subject O and the second camera 121 'can take a right-eye plane image of the subject O.

Accordingly, the 3D image can be provided using the left eye plane image captured by the first camera 121 and the right eye plane image captured through the second camera 121 '. If the left eye image and the right eye image are provided in the left eye and the right eye, the observer can feel the three-dimensional image in the three-dimensional image.

A method of selectively providing the left eye image and the right eye image to the left eye and the right eye, respectively, includes a method of using 3D glasses or a method of providing a parallax barrier layer on the display, and a detailed description thereof will be omitted.

FIG. 2 (b) shows the principle of taking a panoramic image through the portable terminal according to the present invention.

A panoramic image means an image of an object shot at an ultra-wide angle, which means a high-resolution image that can not be shot or observed at one time by a general angle of view or a viewing angle.

In the method of generating a panoramic image using the portable terminal according to the present invention, a horizontal direction image taken by each camera is connected in a horizontal direction.

Assuming that the portable terminal according to the present invention is provided with two cameras for capturing 3D images, the portable terminal according to the present invention may be configured such that the horizontal direction images captured by the first camera 121 and the second camera 121 ' Can provide images.

However, in the photographing process for providing the panoramic image, it is not necessary to photograph the same area of the subject photographed by each camera.

In order to photograph the panoramic image at the maximum wide angle, it is sufficient that the overlapping of the images taken by the respective cameras is avoided, and the boundary regions of the images taken by the respective cameras are naturally connected.

Therefore, when photographing a panoramic image through the portable terminal according to the present invention, the photographing direction of the camera for 3D photographing needs to be changed.

Therefore, as shown in FIG. 2, in order to photograph a 3D image or a panoramic image using two cameras 121 and 121 'mounted on the portable terminal, the photographing direction by each of the cameras 121 and 121' It needs to be changed depending on the type of image.

2 (a), the first camera 121 and the second camera 121 'photograph a region in which the same object is superimposed. Therefore, the first camera 121 121 and the second camera 121 'are set in the directions corresponding to each other.

As shown in FIG. 2 (b), the first camera 121 and the second camera 121 'are arranged such that an overlapping area of the subject is not generated, And the second camera 121 'are set in different directions.

Therefore, two cameras 121 and 121 'are mounted on the same portable terminal, and two cameras 121 and 121' are simultaneously mounted to selectively photograph the 3D image and the panoramic image, Should be mounted so as to be variable.

Hereinafter, with reference to FIG. 3 and subsequent drawings, a portable terminal capable of changing a shooting direction of a camera for shooting a 3D image or a high-resolution image will be discussed.

FIG. 3 shows an embodiment of a portable terminal according to the present invention. More specifically, FIG. 3A is a front perspective view of a closed state of one embodiment of the portable terminal according to the present invention, and FIG. 3B is a rear view of an opened state.

The present invention is characterized in that the present invention includes a first camera 121, a second camera 121 'mounted at a position spaced apart from the first camera 121, at least one or more bodies And a controller for converting an image photographed by the first camera and the second camera into a 3D image, a panoramic image, or a predetermined high-resolution image, wherein the first camera or the second camera photographs And provides a portable terminal whose direction can be changed.

In the portable terminal shown in FIG. 3, two bodies 100A and 100B are slidably coupled. The state in which the first body 100A is disposed so as to overlap with the second body 100B may be referred to as a closed configuration and the first body 100A may be referred to as a second configuration The state in which at least a part of the body 100B is exposed may be referred to as an open configuration.

The portable terminal shown in Fig. 3 operates mainly in the standby mode in the closed state, but the standby mode is released by the user's operation. The above-mentioned (portable terminal) operates mainly in a call shooting mode and the like in the open state, but is also switched to a standby shooting mode by a user's operation or a predetermined time elapse.

The first body 100A may include a display unit 151, an audio output module 152, a first camera 121, or a first user input unit 131-1. In addition, the display unit 151 may overlap the touchpad in a layer structure, so that the display unit 151 may operate as a touch screen to enable information input by a user's touch.

A second user input unit 131-2 may be disposed in the second body 100B.

A third user input unit 131-3, a microphone module, and an interface unit 170 may be disposed on a side surface of the second body 100B.
