Hereinafter, since the display unit 151 may be more easily implemented when the display unit 151 is configured as a touch screen, it is assumed that the display unit 151 is a touch screen.

4 is a flowchart illustrating a method of setting a dimension change area according to an embodiment of the present invention.

As shown in FIG. 4, the display unit 151 displays a screen including an image (S410). The above image may be a preview image (hereinafter, referred to as a preview image of a camera) showing an image to be photographed by a camera, or may be an image previously stored and reproduced in a memory, or an image by executing web browsing. . In addition, not only an image but also an icon for receiving a user command may be displayed on the screen.

The controller 180 obtains the dimensional information of the displayed image and displays it in one area of the screen (S420). For example, when generated by a plurality of cameras such as a left eye camera and a right eye camera, the controller 180 determines that the preview image of the displayed camera is a 3D image. However, it is determined that the image photographed by one camera is a two-dimensional image. The dimension information of the image acquired as described above may be displayed in one region of the image or may be displayed in an edge region of the image.

The controller 180 sets a dimension change area that can receive a dimension change command in some areas of the displayed image (S430). It is preferable that at least one dimension change area is set. When the displayed image is a 2D image, the controller 180 divides a certain region of the image (for example, one image into 5 × 5 blocks, and blocks (2, 3) and (4, 3)). It can be set as the dimension change area. In addition, when the displayed image is a 3D image, the controller 180 may calculate a parallax between the left eye image and the right eye image, and set an area including an area having a maximum parallax as a dimension change area. In addition, when a plurality of dimension change areas are set, the controller 180 may set an area having the maximum parallax as the first dimension change area and then set an area having the maximum parallax as the second dimension change area.

The above-described method for setting the dimension change area is merely an example, and the dimension change area may be set in another manner. Also, the dimension change area may be arbitrarily set by the user.

The controller 180 displays the set dimension change area so as to be distinguishable from the rest of the image (S440). An indicator indicating that the dimension is changed may be displayed, such as displaying a specific icon by overlapping the dimension change area.

As described above, by setting the dimension change area for changing the dimension of the image to a part of the image and displaying it identifiably, the user can easily change the dimension of the image while viewing the image.

5 is a flowchart illustrating a method of displaying a 3D image from a 2D image according to an embodiment of the present invention.

Referring to FIG. 5, a display including a 2D image is displayed on the display unit 151 (S510). In addition, the dimension change area is displayed on a part of the image so as to be distinguished (S520). The case where two dimension change area | regions (1st dimension change area | region and 2nd dimension change area | region) are set is demonstrated as an example. However, it is of course not limited to this. Meanwhile, the controller 180 determines whether a first user command is received through the dimension change area (S530). Here, the first user command refers to a user command of multi-touching the dimensional change area (that is, simultaneously touching the first dimensional change area and the second dimensional change area) and dragging toward the same point in front of the screen. However, the first user command may be a user command for touching the first dimension change command and the second dimension change area for a short time (for example, two seconds).

If it is determined that the first user command has been received (S530-Y), the controller 180 displays a 3D image corresponding to the 2D image (S540). If a 3D image corresponding to the 2D image exists separately, the controller 180 displays the 3D image after signal processing. However, if there is no 3D image corresponding to the 2D image, the 3D image is generated and displayed using the 2D image. For example, when there is depth information about a 2D image and a subject of a 2D image, the controller 180 converts the depth information into displacement information, and includes 3 information including bending information about a three-dimensional shape using the displacement information. Create a 3D image. Then, the generated three-dimensional image is displayed.

On the other hand, it is determined whether a second user command is received through the dimension change area (S550). Here, the second user command refers to a user command of dragging in the first direction (eg, left direction) parallel to the screen after multi-touching the dimension change area.

If it is determined that the second user command has been received (S550-Y), the controller 180 displays an image in which the 2D image and the 3D image are mixed (S560). If a 3D image corresponding to the 2D image exists separately, the controller 180 generates a mixed image by mixing the 2D image and the 3D image and displays the mixed image. However, when there is no 3D image corresponding to the 2D image, it is preferable to generate the 3D image using the 2D image and then mix the 2D image and the 3D image.

In operation S570, it is determined whether a third user command is received through the dimension change area. Here, the third user command refers to a user command of touching the dimension change area with a single touch, that is, touching any one of the first dimension change area and the second dimension change area.

If it is determined that the third user command has been received (S570-Y), the controller 180 displays only an image displayed in the dimension change area, that is, a part of the 2D image as a 3D image (S580). In detail, the controller 180 may crop an image displayed in the dimension change area of the 2D image, generate a 3D image corresponding to the cropped 2D image, and display the combined 2D image. If there is a 3D image corresponding to the 2D image, the controller 180 crops the 3D image corresponding to the portion of the 2D image displayed on the dimension change area, and crops the 3D image instead of the portion of the 2D image. The image may be displayed in combination with the remaining two-dimensional images.

6 is a flowchart illustrating a method of displaying a 2D image from a 3D image according to an embodiment of the present invention.

Referring to FIG. 6, a screen including a 3D image is displayed on the display unit 151 (S610). In addition, the dimension change area is displayed in one area of the image so as to be distinguishable (S620). It is assumed that a plurality of dimension change areas (eg, a first dimension change area and a second dimension change area) are displayed (S630). Meanwhile, the controller 180 determines whether a fourth user command is received through the dimension change area. Here, the fourth user command refers to a user command of dragging in a direction in which parallax decreases after multi-touching (ie, simultaneously touching the first and second dimensional change areas) through the dimensional change area. However, the fourth user command may be a user command for touching the first dimension change command and the second dimension change area for a long time (for example, 4 seconds).

If it is determined that the fourth user command has been received (S630-Y), the controller 180 displays a 2D image corresponding to the 3D image (S640). If a 2D image corresponding to the 3D image exists separately, the controller 180 displays the 2D image after signal processing. However, when the 2D image corresponding to the 4D image does not exist, the 2D image may be displayed by displaying only one of the left eye image and the right eye image as the 3D image. Alternatively, the 2D image may be generated by erasing the depth information from the left eye image and the right eye image. Then, the generated two-dimensional image is displayed.

On the other hand, it is determined whether a fifth user command is received through the dimension change area (S650). Here, the fifth user command refers to a user command of dragging in the second direction (eg, the upward direction) parallel to the screen after multi-touching the dimension change area.

If it is determined that the fifth user command has been received (S650-Y), the controller 180 displays an image in which the 2D image and the 3D image are mixed (S660). When a 2D image corresponding to the 3D image exists separately, the controller 180 generates a mixed image by mixing the 2D image and the 3D image and displays the mixed image. However, when the 2D image corresponding to the 3D image does not exist, it is preferable to generate the 2D image using the 3D image and then mix the 2D image and the 3D image.

In operation 670, it is determined whether a sixth user command is received through the dimension change area. Here, the sixth user command refers to a user command of single touching the dimension change area (that is, touching one of the first dimension change area and the second dimension change area).

If it is determined that the sixth user command is received (S670-Y), the controller 180 displays only an image displayed in the dimension change area, that is, a part of the 3D image as a 2D image (S680). In detail, the controller 180 may crop an image displayed on a dimension change region of the 3D image, generate a 2D image corresponding to the cropped 3D image, and display the combined 2D image. If there is a 2D image corresponding to the 3D image, the controller 180 crops the 2D image corresponding to the part of the 3D image displayed on the dimension change area, and the 2D cropped instead of the part of the 3D image. The image may be displayed together with the remaining 3D images.

7 is a flowchart illustrating a method of displaying a 2D or 3D image from a mixed image according to an embodiment of the present invention.

Referring to FIG. 7, the display unit 151 displays a screen including a mixed image in which a 3D image and a 2D image are mixed (S710). In addition, the dimension change area is displayed in one area of the mixed image to be distinguishable (S720). It is said that two dimension change areas (a first dimension change area and a second dimension change area) are displayed. Meanwhile, the controller 180 determines whether a seventh user command is received through the dimension change area (S730). Here, the seventh user command refers to a user command of multi-touching the dimension change area (that is, simultaneously touching the first dimension change area and the second dimension change area) and then dragging the dimension change area in a third direction parallel to the screen. It is preferable that a 3rd direction is a direction opposite to a 1st direction here. If it is determined that the seventh user command has been received (S730-Y), the controller 180 displays a 2D image (S740).

In operation S750, it is determined whether an eighth user command is received through the dimension change area. Here, the eighth user command refers to a user command of dragging in the fourth direction parallel to the screen after multi-touching the dimension change area. It is preferable here that a 4th direction is a direction opposite to a 2nd direction. If it is determined that the eighth user command has been received (S750-Y), the controller 180 displays a 3D image (S760).

As such, the user may display a 2D image, a 3D image, an image in which a part of the 2D image and a part of the 3D image are combined, and an image in which the 2D image and the 3D image are mixed. The 2D image and the 3D image can be viewed in various ways.

As shown in FIG. 8A, in the state where the 2D image 810 is displayed on the display unit 151, the controller 180 divides the image into an upper region and a lower region, and the center region of the upper region. And the center region of the lower region is set as the dimension change region 820. In addition, the indicator 830 may be displayed in the dimensional change area so that the dimensional change area 820 may be displayed in a distinguishable manner. The type of the indicator 830 may be an icon, or may be variously implemented such as displaying a specific figure or a specific color.

In addition, as shown in FIG. 8B, in a state where the 3D image 840 is displayed on the display unit 151, the controller 180 may determine an area having the largest parallax and an area having the next largest parallax. The dimension change area 850 may be set, and the indicator 860 may be displayed. In addition, the dimensional information 870 and 880 of the displayed image may be displayed.

Then, the controller 180 determines that the position change command of the first dimension change area 1122 is received, and as shown in FIG. 11B, the first dimension change area 1122 corresponds to dragging. Change the position of. The user command 1150 may be input by touching and dragging through the boundary area of the first dimension change area 1142 whose position is changed. Then, the controller 180 determines that the size change command of the first dimension change area 1142 having the changed position is received, and changes and displays the first dimension change area 1162 having the size changed in response to the dragging. Specifically, upon receiving a user command of touching the border of the first dimension change area and dragging it to an inner area of the first dimension change area, the controller 180 controls the size of the first dimension change area in response to the dragged distance. To zoom out. On the other hand, when a user command to touch the border area of the first dimension change area and then drag it to the outside area of the first dimension change area is received, the controller 180 adjusts the size of the first dimension change area in response to the dragged distance. Zoom in to display. Then, when the touch is finished, as shown in FIG. 11C, the 3D image 1170 is displayed instead of the 2D image displayed on the first dimension change region.
