4 to 9 are views for explaining a stereoscopic image display method using binocular parallax associated with embodiments of the present invention.

Binocular parallax (stereo disparity) refers to the difference in the way the left and right eyes of a person see objects. When a human's brain synthesizes the image seen through the left eye and the image seen through the right eye, the synthesized image makes a person feel three-dimensional. In the following description, a phenomenon in which a person feels a stereoscopic sense according to binocular parallax is referred to as 'stereoscopic vision', and an image causing stereoscopic vision is referred to as a 'stereoscopic image'. Also, when a specific object included in the image causes stereoscopic vision, the object is referred to as a 'stereoscopic object'.

The stereoscopic image display method according to binocular disparity is divided into glasses type which requires special glasses and glassesless type which do not need glasses. The spectacles include a method using sunglasses with wavelength selectivity, a polarization glasses method using a light blocking effect according to a polarization difference, and a time-division glasses method alternately presenting left and right images within an afterimage time of an eye. In addition, there is a method in which a filter having different transmittances is mounted in the left and right sides to obtain a stereoscopic effect on the movement in the left and right directions according to the time difference of the visual system coming from the difference in the transmittances.

The lenticular lens array 81a includes a display surface 83 and left and right eyes 82a in which pixels L to be input to the left eye 82a and pixels R to be input to the right eye 82b are alternately arranged along the horizontal direction. Located between 82b), it provides optical discrimination directivity for the pixel L to be input to the left eye 82a and the pixel R to be input to the right eye 82b. Accordingly, the image passing through the lenticular lens array 81a is observed separately from the left eye 82a and the right eye 82a, and the image of the human brain is seen through the left eye 82a and the image seen through the right eye 82b. By synthesizing the three-dimensional image.

Referring to FIG. 5, to display a stereoscopic image, the displays 151 and 251 include a parallax barrier 81b having a vertical grid shape. The parallax barrier 81b includes a display surface 83 and left and right eyes 82a in which pixels L to be input to the left eye 82a and pixels R to be input to the right eye 82b are alternately arranged along the horizontal direction. 82b) between the left eye 82a and the right eye 82b through the vertical lattice-shaped aperture (aperture) to be viewed separately. Therefore, the human brain synthesizes an image viewed through the left eye 82a and an image viewed through the right eye 82b to observe a stereoscopic image.

On the other hand, the above-described three-dimensional image display method for explaining the embodiments of the present invention, the present invention is not limited thereto. The present invention can display a stereoscopic image using binocular disparity using a variety of methods in addition to the above-described method.

6 illustrates an example in which a stereoscopic image including a plurality of image objects 10 and 11 is displayed.

For example, the stereoscopic image illustrated in FIG. 6 may be an image acquired through the camera 121. The stereoscopic image includes a first image object 10 and a second image object 11. Here, although two image objects 10 and 11 are assumed for convenience of description, more image objects may be included in the stereoscopic image.

The controller 180 may display an image acquired in real time through the camera 121 on the displays 151 and 251 in a camera preview format.

The controller 180 may obtain at least one stereo disparity corresponding to each of the at least one image object.

When the camera 121 is a 3D camera capable of acquiring a left eye image and a right eye image, the controller 180 controls the first image object through the left eye image and the right eye image acquired through the camera 121. 10) and binocular disparity of the second image object 11 may be obtained, respectively.

5 is a diagram for describing binocular disparity of an image object included in a stereoscopic image.

For example, referring to FIG. 5, the first image object 10 may include a left eye image 10a viewed by the user as the left eye 20a and a right eye image 10b viewed by the right eye 20b.

The controller 180 may obtain a binocular parallax d1 corresponding to the first image object 10 through the left eye image 10a and the right eye image 10b.

Meanwhile, when the camera 121 is a 2D camera, the controller 180 converts a 2D image obtained through the camera 121 into a 3D image using a predetermined algorithm for converting a 2D image into a 3D image. To be displayed on the displays 151 and 251.

In addition, the controller 180 may use the left-eye image and the right-eye image generated by using the image conversion algorithm, respectively, to determine the binocular disparity of the first image object 10 and the binocular disparity of the second image object 11, respectively. Can be obtained.

FIG. 8 is a diagram for comparing binocular disparity between the image objects 10 and 11 illustrated in FIG. 6.

Referring to FIG. 8, the binocular disparity d1 of the first image object 10 and the binocular disparity d2 of the second image object 11 are different from each other. In addition, as shown in FIG. 8, since the second image object 11 is larger than d1, the second image object 11 may appear to be farther from the user than the first image object 10.

The controller 180 may obtain at least one graphic object corresponding to each of the at least one image object. The controller 180 may display the obtained at least one graphic object on the displays 151 and 251 to have a corresponding binocular disparity.

FIG. 9 illustrates a first image object 10 that may have an effect as if it protrudes toward the user side on the displays 151 and 251. As illustrated in FIG. 7, the positions of the left eye image 10a and the right eye image 10b may be displayed on the displays 151 and 251 as opposed to FIG. 7. When the positions of the left eye image 10a and the right eye image 10b are displayed in reverse, the left eye 20a and the right eye 20b may be shown in opposite directions. Accordingly, the user may feel that the first image object 10 is displayed in front of the displays 151 and 251, which are points of intersection of the eyes. That is, the display 151 and 251 may feel a positive depth. This is different from the case of FIG. 7 in which a negative (-) depth feeling is felt as if the first image object 10 is displayed behind the displays 151 and 251.

If necessary, the controller 180 can display a stereoscopic image to feel a positive or negative depth so that the user can feel various depths.

Alternatively, when the user at the location of the other device can view the display apparatus 200, the other device may be operated in a specific mode regardless of the distance. For example, another device that displays the same image as the display apparatus 200 by changing the image to 2D or 3D according to the distance is specified as 2D or 3D regardless of the distance at the point where the display apparatus 200 is not visible. This means that the image can be displayed in the mode.

12 and 13 illustrate operations of the display apparatus and other devices of FIG. 11.

As shown in these figures, the display apparatus 200 according to an exemplary embodiment may perform various operations with other devices 100, 300, and 400.

As shown in FIG. 12, the display apparatus 200 may be in a certain relationship with certain other devices 100, 300, and 400. For example, certain other devices 100, 300, and 400 may be in a relationship disposed within a predetermined distance from the display apparatus 200.

The distance between the other devices 100, 300, and 400 and the display apparatus 200 may be measured by various methods. For example, distance information measured by the mobile terminal 100 which is one of the other devices 100, 300, and 400 may be transmitted to the display apparatus 200. Alternatively, the display apparatus 200 may obtain distance information from a server (not shown) controlling the devices 100, 300, and 400 that are different from the display apparatus 200.

Other devices 100, 300, and 400 forming a relationship with the display apparatus 200 may vary. However, hereinafter, the mobile terminal 100, which is one of the other devices 100, 300, and 400, will be described to replace the description of the case where the mobile terminal 100 is not.

As illustrated in FIG. 13, the display apparatus 200 and the mobile terminal 100 may exchange data, information, content, and the like. For example, when a user manipulates the mobile terminal 100, at least one of data, information, and content of the second device 400 may be moved to the display apparatus 200. The manipulation of the mobile terminal 100 may be a gesture operation of moving the mobile terminal 100 in a three-dimensional space so as to start the second device 400 to move data and face the display apparatus 200.

The mobile terminal 100 may serve as a remote controller for the device in the direction that the mobile terminal 100 is directed. For example, when the mobile terminal 100 is facing the second device 400, the second device 400 may be remotely operated. When the mobile terminal 100 is facing the first device 300, the first device 300 may be used. It can act as a recoat controller that can be operated remotely.

The mobile terminal 100 may be in an operation mode that serves as a remote controller for the display apparatus 200. That is, the display apparatus 200 may be operated by the mobile terminal 100 without directly accessing the display apparatus 200.

14 and 15 illustrate an operation according to a distance between the display device and the mobile terminal of FIG. 11.

As shown in these figures, the display apparatus 200 according to an embodiment of the present invention may operate in different modes according to distances from other devices 100, 300, and 400.

The mobile terminal 100 may be located within a range of one of the first, second, and third regions R1, R2, and R3 from the display apparatus 200. The first, second, and third regions R1, R2, and R3 may be spaced apart from the display apparatus 200, respectively. That is, the second region R2 is spaced apart from the display apparatus 200 compared to the first region R1, and the third region R3 is spaced apart from the display apparatus 200 compared to the second region R2. It can mean that there is.

According to each of the first, second, and third regions R1, R2, and R3 according to the distance from the display apparatus 200, the mobile terminal 100 may be configured as one of the first, second, and third modes MODE1, 2, and 3. It can operate in one mode.

The first, second, and third modes MODE 1, 2, and 3 may be specific states in which the mobile terminal 100 operates.

The first mode MODE 1 may be a state in which the display apparatus 200 is operated through manipulation of the display apparatus 200 itself. For example, the display apparatus 200 may be a mode in which the display apparatus 200 may be manipulated through a touch on the display 251 of the display apparatus 200, a touch on a button provided on the display apparatus 200, or the like. In the first region R1 operating in the first mode MODE 1, the mobile terminal 100 and the display apparatus 200 are located close to each other by a predetermined distance or less.

The second mode MODE 2 may be a state in which the mobile terminal 100 operates as a remote controller for the display apparatus 200. That is, the mobile terminal 100 may be in a state of operating various functions of the display apparatus 200.

The third mode MODE 3 may be in a state in which the display of the mobile terminal 100 is synchronized with the display of the display apparatus 200. For example, when the display 251 of the display apparatus 200 expresses an image in 3D form, it means that the image may be expressed in 3D form on the display 151 of the mobile terminal 100. In addition, when the display 251 of the display device 200 represents an image in 2D form, it means that the image may be represented in 2D form on the display 151 of the mobile terminal 100. Furthermore, in some cases, the display apparatus 200 and the mobile terminal 100 may express the image in a form opposite to each other. For example, while the display apparatus 200 represents an image in 3D form, the mobile terminal 100 may represent an image in 2D form.

In the third mode (MODE 3), due to the synchronized display of the image between the display device 200 and the mobile terminal 100, the ease of use can be improved. For example, an operation of clearly confirming an image displayed on the display device 200 that is relatively far from the mobile terminal 100 may be possible.

Each operation mode of the mobile terminal 100 may vary according to the distance between the mobile terminal 100 and each device. For example, the mobile terminal 100 operates in a first mode MODE 1 with a device existing in the first area R1, and operates in a first mode MODE 1 with a device existing in the second area R2. 2) can be operated. Since the operation mode for each device is changed and / or set differently according to the distance between the mobile terminal 100 and each device, more active control of another device may be possible using the mobile terminal 100.

FIG. 16 illustrates an operation according to a position between the display device and the mobile terminal of FIG. 11.

As shown in the drawing, in the mobile terminal 100 according to an embodiment of the present invention, an operation mode may be changed depending on whether a user who operates the mobile terminal 100 can observe another device.

The mobile terminal 100 may be located in the first area AREA 1 or the second area AREA 2. The first area AREA 1 is an area in which the display device 200 can be directly observed in the mobile terminal 100, and the second area AREA 2 is a display device 200 in the mobile terminal 100 due to a wall or the like. It may be an area where it cannot be observed.

The controller 180 may allow the mobile terminal 100 to operate in different operation modes in the first area AREA 1 and the second area AREA 2. The fourth and fifth regions R4 and R5 may be substantially the same or similar distance from the display apparatus 200. Although the mobile terminal 100 has no or little variation in distance,

 Depending on whether the display device 200 is observable, the controller 180 can cause the mobile terminal 100 to operate in different operation modes. That is, when the mobile terminal 100 is in an area where the display apparatus 200 cannot be observed, the mobile terminal 100 may operate in a specific operation mode regardless of the distance between the mobile terminal 100 and the display apparatus 200. it means. For example, when the mobile terminal 100 is located in the second area AARA 2, an image displayed on the mobile terminal 200 may be displayed on the display 151 of the mobile terminal 100 regardless of the distance. That means you can.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit and scope of the invention. Accordingly, such modifications or variations are intended to fall within the scope of the appended claims.
