Description

[0001] PORTABLE TERMINAL [0002]

The present invention relates to a mobile terminal including a stereoscopic image camera, and more particularly, to a mobile terminal in which two cameras are respectively fixed.

A mobile terminal is a portable electronic device that is portable and has one or more functions of voice and video call function, information input / output function, and data storing function.

As the functions of the mobile terminal are diversified, the mobile terminal is implemented in the form of a multimedia device having complicated functions such as photographing and photographing of a moving picture, reproduction of a music or video file, and reception of a game and a broadcast.

Various new attempts have been made in terms of hardware or software to implement the complex functions of multimedia devices.

In recent years, cameras have been developed for shooting stereoscopic images. A stereoscopic image camera for capturing a stereoscopic image includes two or more electronic components which must be spaced apart from each other. Generally, the two or more electronic parts are integrally formed and fixed inside the terminal. Further, since the two or more electronic parts must be fixed to be spaced apart from each other, the space occupied inside the terminal is large and the weight becomes heavy. Accordingly, there is a problem that the area occupied by the circuit board for controlling the driving of relatively different electronic components is reduced, and the weight of the entire terminal becomes heavy.

In addition, a stereoscopic image camera module manufactured separately from the terminal uses expensive materials such as aluminum to fix the two or more electronic parts. Therefore, there is a problem that the manufacturing cost of the terminal increases.

SUMMARY OF THE INVENTION Accordingly, the present invention has been made in view of the above problems, and it is an object of the present invention to reduce the space occupied by the stereoscopic image camera.

Further, the object of the present invention is to fix parts of the stereoscopic image camera using a low-cost material.

According to an embodiment of the present invention, there is provided a mobile terminal including a supporting member, first and second camera modules, a circuit board, and first and second camera module holding members. The support member is disposed inside the terminal body, and at least one electronic component is mounted. The first and second camera modules are spaced apart from the electronic component, and are disposed at predetermined intervals in the support member. The circuit board is connected to the first and second camera modules, and generates a stereoscopic image using the images photographed from the first and second camera modules. The first and second camera module fixing members are formed to protrude from the support member and fix the first and second camera modules to fix the first and second camera modules, respectively.

According to an example of the present invention, the support member and the first and second camera fixing members are formed of stainless steel.

According to an example of the present invention, the support member and the first and second camera module securing members are fixed to the support member by welding, and the first and second camera module securing members are parallel to the support member And at least one protrusion protruding from the protrusion.

According to an embodiment of the present invention, the electronic component includes a battery, and a battery fixing member is formed to protrude from the support member and enclose the battery to fix the battery.

According to an example of the present invention, the first camera module fixing member, the second camera module fixing member, and the battery fixing member are integrally formed.

According to one example of the present invention, the first and second camera module holding members are respectively provided with a first member, a second member facing the first member, and a third member connecting the first and second members . The first and second camera modules are housed in a space formed by the first, second, and third members, respectively.

According to one embodiment of the present invention, the first and second camera module holding members each include a fourth member facing the third member.

According to an exemplary embodiment of the present invention, a mobile terminal includes a flexible printed circuit board connected to the first and second camera modules to transmit input video signals, respectively. And the fourth member includes an opening formed in a region corresponding to the flexible printed circuit board.

According to the present invention, the first and second camera modules of the rear camera are fixed by a fixing member protruding from a supporting member for supporting other electronic components inside the terminal main body. Therefore, it is unnecessary to provide a configuration in which the first and second camera modules are integrally fixed in the spacing spaces of the first and second camera modules.

Therefore, since the empty space is secured between the first and second camera modules, the circuit board can be formed in the spacing space.

In addition, since the configuration formed between the first and second camera modules can be omitted, the weight of the mobile terminal can be reduced.

Further, according to the present invention, since the fixing portion of the parts is formed of the same material as the supporting member, the cost of mounting the rear camera can be reduced.

The stereoscopic image that can be implemented on the display unit 151 of the portable terminal according to the present invention may be a monoscopic image in which the same image is provided in both eyes and a different image in both eyes (Streo scopic).

The monoscopic method in which the same image is provided in both eyes has an advantage that it can be implemented as a general display unit. More specifically, the control unit 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 from a specific point on the display unit 151 . Therefore, the substantial part of such a stereoscopic image can be referred to as a planar image.

The way in which different images are provided in both eyes (streo scopic) is a method using the principle of feeling a three-dimensional feeling when a person looks at an object with the naked eye. That is, 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 stereoscopic image. Therefore, though there is some difference in each person, the binocular disparity due to the distance between the two eyes becomes three-dimensional.

The present invention includes two cameras for capturing a left eye image and a right eye image, respectively, which are photographed using binocular disparity, respectively, to form a three-dimensional sensation.
