The present invention relates to a portable terminal capable of shooting a 3D image; More specifically, the present invention relates to a portable terminal capable of capturing 3D images using two cameras (binocular camera) as well as capturing 3D images capable of displaying 2D images.

Recently, the trend of displaying 3D images on large TVs is increasing. It is difficult to implement a 3D image through a display device without processing a general 2D image, and the image captured by the 3D image is displayed on a 3D image display device. Of course, it is also possible to convert to a 3D image using a 2D image, but it is preferable to shoot a 3D image from the beginning because the quality difference is remarkably generated compared to the data directly captured in the 3D image.

And it is not easy to shoot 3D video by general people who are not experts in the industry, but with the increase of devices that can display 3D video recently, the equipment to shoot 3D video will be popularized more easily. It is expected.

However, since the 3D display device that can immediately check the 3D image taken, the manufacturing cost is considerable, so it is too much to apply to a portable terminal (PMP or mobile communication terminal, etc.) with a 3D image recording function that can take the image in public have.

The present invention is to solve the above problems; SUMMARY OF THE INVENTION An object of the present invention is to provide a portable terminal capable of capturing 3D images through a binocular camera while being able to display 2D images directly through a display panel, thereby enabling cheaper and more popular 3D imaging.

The present invention also provides The 2D video interface unit and the 3D video interface unit may output an image by any one of a parallel method, a secure digital I / O (SDIO) method, and a mobile industry processor interface (MIPI) method.

The present invention also provides An external device interface outputting the output interface unit to display an image output from the 3D image interface unit or an image stored in the memory unit in an external device capable of displaying a 3D image; A display panel interface configured to output a 2D image output from the 2D image interface unit to be displayed on the display panel; .

According to the portable terminal capable of taking a 3D image according to the present invention having the configuration as described above; Only the 3D image data captured and converted by the first and second cameras are stored in the memory unit or transferred through the external device interface, and the display panel directly displays the 2D image captured by the first camera or the second camera. It can work.

Accordingly, the photographer can shoot and store high quality 3D images while visually checking through the display panel, and the display panel adopts a type that can display a normal 2D image without increasing the manufacturing cost of the portable terminal. There is an advantage to manufacture / sell more popular products.

In addition, the 3D image interface unit outputs the 3D image to the memory unit in various ways, so that the 3D image can be displayed even if the specifications are linked to other external 3D image-display devices.

The preferred embodiments of the present invention will be described in more detail with reference to the accompanying drawings, in which the technical parts already known will be omitted or compressed for simplicity of explanation.

Referring to FIG. 1; The portable terminal capable of capturing 3D images according to the present invention includes a main body 100 provided with a display panel 130 at a front portion thereof, and a first and second camera 110 mounted at a rear portion of the main body for 3D image capture. (The portable terminal according to the present invention is an example of a mobile communication terminal having various functions such as a communication function, and detailed description of other functions such as a communication function other than the image capturing process is omitted).

The main body 100 of the portable terminal is made of a plate type (also called a bar-type) having a predetermined thickness, and is provided with a touch screen type display panel 130 on the front thereof. Speakers (not shown) and microphones (not shown) for voice calls are mounted on an upper portion and a lower portion of the front surface of the main body 100, and various electrical components are housed in the main body 100. In addition, the display panel 130 is provided to display the state of the portable terminal or to display a 2D image photographed through the first camera 110 or the second camera 120. It is also possible to recognize and convert it into an electrical signal for output.

The first camera 110 and the second camera 120 have the same horizontal optical axis mounted on the upper side of the main body 100, and are simultaneously driven when capturing 3D images, but separately capturing 2D images.

In addition, the portable terminal according to the present invention to process the image signal photographed through the first, second camera 110, 120, as shown in Figure 2, 3D image generating unit 140, 3D image interface It includes a unit 150, a 2D video interface unit 160, an output interface unit 170 and a memory unit 180, the detailed functions of each component is as follows.

First, the 3D image generating unit 140 is a place where the 2D images photographed by the first camera 110 and the second camera 120 are input, respectively, to generate a 3D image using the input 2D image. At this time, the generation of the 3D image, the two 2D images photographed and input from the first camera 110 and the second camera 120 are attached side by side in the form of Side by Side or Top and Bottom, and Line by Line, Pixel Base , sub pixel base, and frame switching. Thus, the 2D image input from the first camera 110 and the second camera 120 and the 3D image generated by converting the 2D image may coexist in the 3D image generating unit 140.

The 3D image interface unit 150 is an interface for transmitting the 3D image generated by the 3D image generating unit 140 to the memory unit 180. The output method applied at this time is a parallel method, SDIO (Secure Dgital I / O). One of the method and the Mobile Industry Processor Interface (MIPI) method may be applied, and other output methods may be applied if necessary. This is to output the 3D image to the memory unit 180 in various ways, so that the 3D image can be displayed even if the specifications are linked to the external device 200 capable of displaying different 3D images.

The 2D image interface unit 160 is an interface for transmitting 2D images before being converted into 3D images from the 3D image generating unit 140, and displays any one of two 2D images input to the 3D image generating unit 140. Send to panel 130. In this case, the 2D image transmitted through the 2D image interface unit 160 transmits a high quality 2D image when there is a difference in the image quality of the 2D image photographed by the first camera 110 and the second camera 120. In the case of the same image quality, either will be irrelevant.

The output interface unit 170 receives the 3D image and the 2D image output from the 3D image interface unit 150 and the 2D image interface unit 160, respectively, and outputs them again. The external device interface 172 and the display panel are displayed. And an interface 174.

The external device interface 172 is electrically connected to the 3D image stored in the memory unit 180 or the 3D image output from the 3D image interface unit 150 to an external device 200 (a display device capable of displaying 3D images). This is where it takes place. The external device interface 172 of the present invention may be connected to an interface such as HDMI (High Definition Multimedia Interface) or USB (Universal Serial Bus), and may be electrically connected to the external device 200 to send 3D images.

In addition, the display panel interface 174 is an interface in which the 2D image interface unit 160 and the display panel 130 are directly connected, and transmits the 2D image transmitted through the 2D image interface unit 160 to the display panel 130. Can be displayed here.

As described above, the memory unit 180 is a space in which a 3D image output through the 3D image interface unit 150 is input and stored. Thus, when the external device 200 capable of displaying the 3D image is connected to the portable terminal 100 of the present invention, the output interface is outputted by outputting the 3D image stored in the memory unit 180 to the output interface unit 170. The 3D image may be displayed on the external device 200 through the external device interface 172 of the unit 170.
