In addition, with respect to the detailed description of the drawings, similar components may be represented by similar figure numerals.

[0050] In the present disclosure, terms such as “have”, “may have”, “include” and “may include” should be interpreted as indicating characteristics and elements such as values, functions, operations and components, and the terms are not intended to exclude the existence of additional characteristics.

[0051] In addition, in the present disclosure, the expression "A or B", "at least one of A and / or B", or "one or more of A and / or B", etc. may include all possible combinations of the listed items. For example, "A or B", "at least one of A and B", or "at least one of A or B" may refer to all of the following situations: (1) including at least one A, (2) including at least one B, or (3) including at least one A and at least one B.

[0052] In addition, the expressions "first", "second", etc. used in the present disclosure may be used to describe various elements, regardless of any order and / or degree of importance. In addition, such expressions are only used to distinguish one element from another element and are not intended to limit the elements.

[0053] In addition, the description that one element (e.g., the first element) is "(operably or communicatively) coupled" to another element (e.g., the second element) / one element (e.g., the first element) is "(operably or communicatively) coupled to" another element (e.g., the second element) or one element (e.g., the first element) is "connected to" another element (e.g., the second element) in the present disclosure should be interpreted as including both the case where the one element is directly coupled to the other element and the case where the one element is coupled to the other element through another element (e.g., the third element). Conversely, the description that one element (e.g., the first element) is "directly coupled to" or "directly connected to" another element (e.g., the second element) may be interpreted as indicating that there is no another element (e.g., the third element) between the one element and the other element.

[0054] In addition, in the present disclosure, a "module" or "component" performs at least one function or operation, and may be implemented as hardware or software, or as a combination of hardware and software. In addition, in addition to a "module" or "component" that needs to be implemented as specific hardware, a plurality of "modules" or "components" may be integrated into at least one module and implemented as at least one processor.

The term "configured to" does not necessarily mean that the device is "specially designed to" in terms of hardware. On the contrary, in some cases, the expression "a device configured to..." may mean that the device is "capable of" performing operations together with another device or component. For example, the phrase "a processor configured to perform A, B, and C" may refer to a dedicated processor (e.g., an embedded processor) for performing the corresponding operations, or a general-purpose processor (e.g., a CPU or an application processor) that can perform the corresponding operations by executing one or more software programs stored in a memory device.

[0056] Hereinafter, the present disclosure will be described in detail with reference to the accompanying drawings.

[0057] Figure 1A and Figure 1B is a diagram illustrating a display device according to an embodiment.

[0058] According to an embodiment, the display device 100 may be implemented as a TV. However, the display device 100 is not limited thereto.

[0059] In addition, as in Figure 1A and Figure 1B In the embodiment, the display device 100 may include a rotatable display 110 .

[0060] Specifically, the display device 100 may include a bracket 10, and the display 110 may be installed to be rotatable on the bracket 10. For example, the display device 100 may include a motor for rotating the display 110, etc.

[0061] like Figure 1A and 1B As shown, the display device 100 can rotate the display 110 oriented (arranged) in the horizontal direction (or horizontal orientation) to be oriented in the vertical direction (or longitudinal orientation). In addition, the display device 100 can rotate the display 110 oriented (arranged) in the vertical direction to be oriented in the horizontal direction.

[0062] The display device 100 may include a plurality of cameras 120 - 1 , . . . , 120 - n (here, n is an integer greater than or equal to 2).

[0063] Here, a plurality of cameras 120 - 1 , . . . , 120 - n may be provided at one side of a housing of the display apparatus 100 .

[0064] For example, refer to Figure 1A and Figure 1B In the case where the width of the display 110 is longer than the length, the plurality of cameras 120 - 1 , . . . , 120 - n may be disposed on relatively short vertical sides in the housing of the display 110 .

[0065] However, this is merely an example, and the plurality of cameras 120-1, ..., 120-n may be disposed in the bezel area of ​​the display 110, and in this case, the plurality of cameras 120-1, ..., 120-n may be disposed in the bezel area on a relatively short vertical side.

[0066] exist Figure 1A and Figure 1B , it is shown that there are only two cameras 120 - 1 and 120 - 2 , but this is only an example, and the display device 100 may include two or more cameras.

[0067] Hereinafter, for convenience of explanation, it will be assumed that the display device 100 includes two cameras 120-1 and 120-2 for photographing images. Here, the term "photographing images" refers to capturing a moving image (video) or one or more still images / pictures.

[0068] The plurality of cameras 120 - 1 and 120 - 2 may be rotated, and the display apparatus 100 may include a motor or the like for rotating each of the cameras 120 - 1 , 120 - 2 .

[0069] In this case, each camera 120-1 and 120-2 may be rotated in the up-down direction and the left-right direction in the housing including the plurality of cameras 120-1 and 120-2, respectively, or the housing including the plurality of cameras 120-1 and 120-2 itself may be rotated in the up-down direction and the left-right direction.

[0070] Therefore, the photographing directions of the cameras 120 - 1 and 120 - 2 may be changed.

[0071] For example, when each camera 120-1 and 120-2 is rotated in the upward direction or the downward direction, the shooting direction of each camera 120-1 and 120-2 may be changed to be more upward or more downward than the direction before the rotation. In addition, when each camera 120-1 and 120-2 is rotated in the left direction or the right direction, the shooting direction of each camera 120-1 and 120-2 may be changed to be more leftward or more rightward than the direction before the rotation.

[0072] Therefore, the display apparatus 100 may control the camera according to the arrangement state of the display 110 (for example, whether the display 110 is arranged in the horizontal direction or in the vertical direction), and a more detailed explanation will be provided below.

[0073] Figure 2 is a block diagram showing a configuration of a display device according to an embodiment.

[0074] Reference Figure 2 , the display device 100 may include a display 110 , a plurality of cameras 120 - 1 and 120 - 2 , and a processor 130 .

[0075] The display 110 may be installed on the display device 100 to be rotatable.

[0076] For example, the display 110 may be mounted on the bracket 10 so as to allow the display device 100 to stand from the ground or floor, and the display 110 may be arranged in a horizontal direction or a vertical direction. In addition, the display 110 arranged in the horizontal direction may be rotated to a vertical direction, and the display 110 arranged in the vertical direction may be rotated to a horizontal direction. To this end, the display device 100 may include a motor for rotating the display 110, etc.

[0077] In addition, the display 110 may be implemented as various types of displays such as a liquid crystal display (LCD), a light emitting diode (LED), an organic light emitting diode (OLED), a quantum dot light emitting diode (QLED), and the like.

[0078] The plurality of cameras 120-1 and 120-2 may respectively capture images. To this end, each of the cameras 120-1 and 120-2 may include an image sensor, a lens, and the like.

[0079] Here, the plurality of cameras 120-1 and 120-2 may be arranged at different angles from each other. For example, the plurality of cameras 120-1 and 120-2 may include a first camera 120-1 that captures images using a normal lens and a second camera 120-2 that captures images using a wide-angle (or ultra-wide-angle) lens having a larger viewing angle than the normal lens.

[0080] The processor 130 may control the overall operation of the display device 100. Specifically, the processor 130 may be electrically connected to the display 110 and the plurality of cameras 120-1 and 120-2, and control these components.

[0081] The processor 130 may include a central processing unit (CPU) or an application processor (AP). In addition, the processor 130 may execute one or more software programs stored in the memory according to at least one instruction stored in the memory of the display device 100.

[0082] For example, in the case where the display 110 is arranged in a vertical direction, the processor 130 may perform photographing by using one of the plurality of cameras 120 - 1 and 120 - 2 . Then, the processor 130 may display the photographed image on the display 110 .

[0083] When the display 110 is arranged in the vertical direction, if an application for photographing a picture or a moving image according to a user command or an application for a video call is executed, the processor 130 may perform photographing by using one of the plurality of cameras 120-1 and 120-2.

[0084] In this case, the processor 130 may perform photographing by using the first camera 120 - 1 among the plurality of cameras 120 - 1 and 120 - 2 , which may perform photographing by using a normal lens.

[0085] If a user command for rotating the display 110 arranged in the vertical direction to the horizontal direction is input, the processor 130 may rotate the display 110 to the horizontal direction.

[0086] Specifically, the processor 130 may drive a motor for rotating the display 110 and thereby rotate the display 110 from a vertical orientation to a horizontal orientation.

[0087] Here, the user command may be received from a remote controller for controlling the display apparatus 100 , or the user command may be input through a button or a touch screen provided on the display apparatus 100 .

[0088] The processor 130 may rotate the display 110 to the horizontal direction according to a user command and stop photographing through the camera. That is, the processor 130 may stop photographing through the first camera 120-1 that is performing photographing when the display 110 is arranged in the vertical direction.

[0089] In contrast, the processor 130 may perform photographing by using the second camera 120 - 2 .

[0090] Here, the second camera 120-2 may be a camera having a larger viewing angle than the first camera 120-1. That is, the second camera 120-2 may be a camera that performs photographing by using a wide-angle (or ultra-wide-angle) lens having a larger viewing angle than a normal lens.

[0091] Specifically, the processor 130 may perform photographing by using the first camera 120-1 among the multiple cameras 120-1 and 120-2 when the display 110 is arranged in a vertical direction, and if a user command for rotating the display 110 to a horizontal direction is input, the processor 130 may rotate the display 110 to a horizontal direction, stop photographing through the first camera 120-1, and perform photographing through the second camera 120-2.

[0092] Then, the processor 130 may control the display 110 to display the image photographed by the second camera 120 - 2 .

[0093] Therefore, in a case where the display 110 is arranged in the horizontal direction, an image photographed by the second camera 120 - 2 may be displayed on the display 110 .

[0094] In this case, the processor 130 may recognize an object included in the image captured by the first camera 120-1 in the image captured by the second camera 120-2, and display the image captured by using the second camera 120-2 on the display 110 so that the recognized object is displayed in the central area of ​​the display 110 arranged in the horizontal direction.

[0095] Specifically, when the display 110 is arranged in the vertical direction, the processor 130 may capture an image through the first camera 120-1 and recognize an object in the captured image. Here, the object may include a person's face, etc.

[0096] Then, the processor 130 may rotate the display 110 arranged in the vertical direction to the horizontal direction according to a user command, and as the display 110 rotates, the processor 130 may control the first camera 120-1 to stop photographing and control the second camera 120-2 to start photographing.

[0097] In this case, the processor 130 may recognize the same object in the image captured by the second camera 120-2 as the object recognized in the image captured by the first camera 120-1. Based on recognizing the same object in the image captured by the second camera 120-2, the image captured by the second camera 120-2 may be displayed on the display 110 arranged in the horizontal direction so that the recognized object is displayed in the central area of ​​the display 110 arranged in the horizontal direction.

[0098] That is, the processor 130 may detect a region including a person's face in an image captured by the first camera 120 - 1 by using a face detection algorithm or the like, and acquire first feature data by analyzing eyes, nose, mouth, etc. in the detected region.

[0099] Then, the processor 130 may detect an area including a face in the image captured by the second camera 120-2, and acquire second feature data by analyzing eyes, nose, mouth, etc. in the detected area. Then, the processor 130 may compare the second feature data with the first feature data acquired in the image captured by the first camera 120-1, and determine a facial area whose feature data is consistent (or matched) in the image captured by the second camera 120-2.

[0100] That is, the processor 130 may determine a region including the same face as the face recognized in the image photographed by the first camera 120 - 1 in the image photographed by the second camera 120 - 2 .

[0101] Then, the processor 130 may display the image photographed by the second camera 120 - 2 on the display 110 such that the area determined in the image photographed by the second camera 120 - 2 is displayed in the central area of ​​the display 110 arranged in the horizontal direction.

[0102] In addition, if a user command for rotating the display 110 arranged in the horizontal direction to the vertical direction is input, the processor 130 may rotate the display 110 in the vertical direction and stop photographing through the second camera 120 - 2 .

[0103] In this case, the processor 130 may capture an image through the first camera 120 - 1 and display the captured image on the display 110 arranged in the vertical direction.

[0104] As described above, the display apparatus 100 may change a camera that performs photographing according to the arrangement state of the display 110 .

[0105] According to the above-mentioned embodiment, the problem that the user must switch his or her position according to the arrangement of the display is solved. Specifically, if the display 110 is rotated, the position where the camera performs shooting is changed, and in this case, the user must change his or her place or position as the display 110 is rotated so that his or her appearance can be accurately photographed, and this may cause inconvenience to the user.

[0106] Therefore, when the display 110 is arranged in a vertical direction, a first image may be captured by the first camera 120-1, and then, if the display 110 is rotated to a horizontal direction, a second image may be captured by using the second camera 120-2 having a larger viewing angle than the first camera 120-1.

[0107] This is because, if the display 110 is rotated from the vertical direction to the horizontal direction, the position of the camera is changed to be relatively more leftward or more rightward than when the direction is the vertical direction. Therefore, in the case where the display 110 is arranged in the horizontal direction, the processor 130 performs photographing by using a camera having a relatively wider viewing angle than the camera used when the direction of the display 110 is arranged in the vertical direction.

[0108] The processor 130 may then detect a face detected in an image captured when the display 110 is in a vertical orientation, in an image captured when the display 110 is in a horizontal orientation, and display the captured image on the display 110 arranged in the horizontal orientation so that an area including the detected face is displayed in a central portion of the display 110 arranged in the horizontal orientation.

[0109] Therefore, even if the position of the camera that performs photographing is changed as the direction of the display 110 is changed, the image of the user can be correctly photographed and provided to the user without causing inconvenience to the user.

[0110] For example, refer to Figure 3A , when the display 110 is arranged in the vertical direction, the processor 130 may capture an image by using the first camera 120 - 1 among the plurality of cameras 120 - 1 and 120 - 2 and display the captured image 310 on the display 110 .

[0111] Then, in response to a user command for rotating the display 110 arranged in the vertical direction to the horizontal direction being input, the processor 130 may rotate the display 110 to be arranged in the horizontal direction.

[0112] In this case, refer to Figure 3B , the processor 130 may stop photographing using the first camera 120 - 1 , and start photographing an image using the second camera 120 - 2 , and display the photographed image 320 on the display 110 .

[0113] Here, the processor 130 may detect a face detected in an image 310 captured when the display 110 is in a vertical direction, in an image captured when the display 110 is in a horizontal direction, and display the captured image on the display 110 arranged in the horizontal direction, so that an area including the detected face is displayed in a central portion of the display 110 arranged in the horizontal direction.

[0114] That is to say, referring to Figure 3A and Figure 3B, when the display 110 is arranged in the horizontal direction, the display device 100 can capture an image through a camera having a larger viewing angle than when the display 110 is arranged in the vertical direction. Therefore, even if the shooting starts when the display 110 is in the vertical direction and the display 110 is rotated in the horizontal direction thereafter, an image correctly capturing the user can be provided.

[0115] In the aforementioned embodiment, it is described that if the display 110 is rotated to the horizontal direction, photographing by the first camera 120 - 1 is stopped and photographing is performed by the second camera 120 - 2 , but this is merely an example.

[0116] As another example, when the display 110 is arranged in the horizontal direction, the processor 130 may continue to capture an image by using the first camera 120 - 1 among the plurality of cameras 120 - 1 and 120 - 2 .

[0117] In this case, when the display 110 is arranged in a vertical direction, the processor 130 may detect an area including a person's face in an image captured by the first camera 120-1, and acquire first feature data by analyzing eyes, nose, mouth, etc. in the detected area.

[0118] Then, if a user command for rotating the display 110 is input, the processor 130 may rotate the display 110 so that the display 110 is arranged in a horizontal direction.

[0119] Here, in the case where the display 110 is arranged in the horizontal direction, the processor 130 may also perform photographing through the first camera 120 - 1 .

[0120] That is, the processor 130 may not stop photographing through the first camera 120 - 1 and perform photographing through the first camera 120 - 1 even after the display 110 is arranged in the horizontal direction.

[0121] Then, when the display 110 is arranged in the horizontal direction, the processor 130 may detect an area including a face of a person in an image captured by the first camera 120-1, and acquire second feature data by analyzing eyes, nose, mouth, etc. in the detected area.

[0122] In this case, if the first feature data acquired from the image captured when the display 110 is arranged in the horizontal direction and the second feature data acquired from the image captured when the display 110 is arranged in the vertical direction are consistent or match, the processor 130 may perform photographing by using the first camera 120-1.

[0123] However, if a facial area is not detected from an image captured when the display 110 is arranged in a horizontal direction, or if the second feature data is not acquired from an image captured when the display 110 is arranged in a horizontal direction or from an image captured when the display 110 is arranged in a vertical direction, the processor 130 may stop capturing by the first camera 120-1 and perform capturing by using the second camera 120-2.

[0124] According to an embodiment, in the case where the display device 100 stands on the ground or floor using the stand 10, the display device 100 may be configured as, for example, Figure 4 Shown standing at an inclined angle θ from the ground.

[0125] For example, if the display device 100 is tilted, the shooting direction 410 of the camera may point upward at a certain angle relative to the horizontal plane. Therefore, if the width of the camera's viewing angle is not wide enough to capture the user's image, the camera may not accurately or correctly shoot the user in front of the display device 100.

[0126] Therefore, the display apparatus 100 may recognize the tilt angle at which the display 110 is tilted, and capture an image by rotating the camera based on the recognized tilt angle.

[0127] Here, the display device 100 may further include a sensor. Here, the sensor may include at least one of an acceleration sensor, a tilt sensor, a gyro sensor, or a 3-axis magnetic sensor. The sensor may collect data and transmit the sensed data to the processor 130.

[0128] For example, if the sensor is an acceleration sensor, the sensor may measure gravity acceleration of each of the X-axis, the Y-axis, and the Z-axis of the display 110 .

[0129] Here, in the case where the display device 100 stands obliquely from the horizontal plane, the display 110 mounted on the bracket 10 may also be arranged obliquely. Therefore, the gravitational acceleration of at least one axis measured by the sensor may be measured as a value other than 0 m / sec2, and here, the square root of the sum of the squares of the components of the three axes (i.e., the magnitude of the vector sum) may be a specific value (e.g., 9.8 m / sec2). The sensor may detect the corresponding accelerations in the X-axis, Y-axis, and Z-axis directions on the coordinate system. Here, each axis and the gravitational acceleration corresponding to each axis may be changed according to the position of the sensor attached to the display device 100.

[0130] The processor 130 may recognize the tilt angle of the display 110 by using the gravity acceleration transmitted from the sensor.

[0131] Here, the tilt angle may refer to an angle at which the display 110 is tilted relative to a plane perpendicular to the ground or floor on which the display device 100 stands. That is, the tilt angle is an angle between the surface of the display 110 and a plane perpendicular to the ground or floor.

[0132] In this case, the processor 130 may calculate the tilt angle of the display 110 (eg, Figure 4 θ in θ).

[0133] In the aforementioned embodiment, it is described that the processor 130 determines the tilt angle of the display 110 by using an acceleration sensor, but this is merely an example, and the processor 130 may determine the tilt angle of the display 110 by using various sensors such as a tilt sensor, a gyro sensor, a magnetic sensor, etc.

[0134] As described above, the processor 130 may recognize the tilt angle of the display 110 based on the sensing data received from the sensor.

[0135] In addition, the processor 130 may recognize a tilt angle of the display 110 based on sensing data received from the sensor when the display 110 is arranged in a vertical direction.

[0136] Then, the processor 130 may rotate the photographing angle of the camera based on the recognized tilt angle. Here, the camera may be the first camera 120-1.

[0137] Specifically, the processor 130 may determine the tilt angle of the display 110 when the display 110 is arranged in the vertical direction, and drive the motor of the first camera 120-1 to rotate the photographing angle of the first camera 120-1 in the downward direction by the determined tilt angle.

[0138] For example, refer to Figure 5A , we may assume that the tilt angle of the display 110 is θ1° when the display 110 is arranged in the vertical direction.

[0139] In this case, if Figure 5B As shown, the processor 130 may rotate the photographing angle of the first camera 120-1 in the downward direction by up to θ1°. Here, the processor 130 may rotate the first camera 120-1 in the downward direction in the housing, or rotate the housing itself including the first camera 120-1.

[0140] Therefore, if Figure 5A and Figure 5BAs shown, the angle of view 520 of the first camera 120-1 is directed downward by as much as θ1° compared to the angle of view 510 before the first camera 120-1 is rotated. Therefore, the display device 100 can more accurately capture a user in front of the display device 100.

[0141] In addition, if the display 110 arranged in the vertical direction is rotated to the horizontal direction based on a user command for rotating the display 110 , the processor 130 may recognize the tilt angle of the display 110 based on sensing data received from the sensor.

[0142] Then, the processor 130 may rotate the photographing angle of the camera based on the recognized tilt angle. Here, the camera may be the second camera 120-2.

[0143] Specifically, when the display 110 is arranged in the horizontal direction, the processor 130 may determine the tilt angle of the display 110 and drive the motor of the second camera 120 - 2 to rotate the photographing angle of the second camera 120 - 2 in the downward direction by as much as the tilt angle.

[0144] For example, refer to Fig. 6A , it can be assumed that the tilt angle of the display 110 is θ2° when the display 110 is arranged in the horizontal direction.

[0145] In this case, if Figure 6B As shown, the processor 130 may rotate the photographing angle of the second camera 120-2 in the downward direction by up to θ2°. Here, the processor 130 may rotate the second camera 120-2 in the downward direction in the housing, or rotate the housing itself including the second camera 120-2.

[0146] Therefore, if Fig. 6A and Figure 6B As shown, the viewing angle 620 of the second camera 120-2 is reduced by as much as θ2° compared to the viewing angle 610 before the second camera 120-2 is rotated. Therefore, the display device 100 can more accurately capture the user in front of the display device 100.

[0147] As described above, according to the embodiment, the photographing direction of the camera is changed according to the degree of inclination of the display 110 relative to the ground. Therefore, the user in front of the display device 100 can be photographed more accurately.

[0148] As another example, the user may want to change the orientation of the display 110 depending on the purpose of using the display device 100 .

[0149] For example, when the user wants to take a picture of himself or herself by using a camera, or to perform a video call with another user by using a camera, the user may want to arrange the display 110 in a vertical direction. In addition, when the user wants to view an image by broadcasting (particularly, an image whose width is longer than its length) or a game, the user may want to arrange the display 110 in a horizontal direction.

[0150] As indicated above, depending on the orientation in which the display 110 is arranged, the camera may or may not be used.

[0151] For example, when the user does not use the camera, the display device 100 may automatically cover the camera by using a camera cover and thereby protect the user's privacy.

[0152] Specifically, when the display 110 is arranged in the vertical direction, the processor 130 may capture an image by using the first camera 120 - 1 among the plurality of cameras 120 - 1 and 120 - 2 .

[0153] For example, if an application for photographing a picture or a moving image according to a user command is executed or an application for a video call is executed when the display 110 is arranged in a vertical direction, the processor 130 may perform photographing by using the first camera 120-1.

[0154] Then, when a user command for ending the executed application is input, the processor 130 may end the executed application and stop photographing through the first camera 120 - 1 .

[0155] Thereafter, if a user command for rotating the display 110 arranged in the vertical direction to the horizontal direction is input, the processor 130 may rotate the display 110 to the horizontal direction.

[0156] In this case, the processor 130 may drive the camera cover so that the camera cover covers the plurality of cameras 120 - 1 and 120 - 2 .

[0157] Specifically, when the display 110 is rotated to the horizontal direction, or after the display 110 is rotated to the horizontal direction, the processor 130 may drive the camera cover to cover the plurality of cameras 120 - 1 and 120 - 2 .

[0158] Therefore, when the display 110 is arranged in the horizontal direction, the plurality of cameras 120 - 1 and 120 - 2 may be covered.

[0159] For example, refer to Fig. 7A , when the display 110 is arranged in a vertical direction, if an application for capturing a picture or a moving image is executed, the processor 130 may capture a user located in front of the display device 100 by using the first camera 120 - 1 and display the captured image 710 on the display 110 .

[0160] Then, when a user command for ending the executed application is input, the processor 130 may end the application.

[0161] Thereafter, if a user command for rotating the display 110 is input, the processor 130 may rotate the display 110 to a horizontal direction.

[0162] In this case, if Figure 7B As shown, the processor 130 may cover the plurality of cameras 120 - 1 and 120 - 2 via the camera cover 20 .

[0163] Thereafter, if a user command for displaying a broadcast is input, the processor 130 may display a broadcast image 720 on the displays 110 arranged in a horizontal direction based on a broadcast signal received from an external device providing the broadcast signal.

[0164] As described above, when the user does not want to use the camera, the display device 100 covers the camera by using the camera cover. Therefore, the privacy of the user can be protected. However, the method of covering the camera is not limited thereto.

[0165] Figure 8 is a block diagram showing a detailed configuration of a display device according to an embodiment.

[0166] Reference Figure 8 , the display device 100 may include a display 110, a plurality of cameras 120 (120-1 and 120-2), a processor 130, a sensor 140, an interface 150, a communication interface 160, a speaker 170, and a memory 180. Here, these components may be controlled by the processor 130.

[0167] Figure 8 The components shown are merely examples, and according to embodiments, at least some components can be omitted, or other components can be added.

[0168] The display 110 , the plurality of cameras 120 , and the processor 130 may perform the functions as described above, and thus repeated explanations for these components will be omitted.

[0169] The sensor 140 may include at least one of an acceleration sensor, a tilt sensor, a gyro sensor, or a magnetic sensor, and may transmit sensed data to the processor 130 .

[0170] In this case, the processor 130 may determine the tilt angle and rotation, etc. of the display 110 by using the sensing data received from the sensor 140. Here, the method of measuring the tilt angle and rotation, etc. of the display 110 by using an accelerometer, etc. may be implemented in various methods.

[0171] The interface 150 may be connected with various external devices. As an example, the interface 150 may be connected with the external device by using various communication methods such as a high-definition multimedia interface (HDMI), a universal serial bus (USB), etc.

[0172] The interface 150 may include an HDMI interface 151 including at least one HDMI port for HDMI communication and a USB interface 152 including a USB port for USB 2.0 and / or USB 3.0 communication.

[0173] The external device may include a dongle, a set-top box, etc. In this case, the HDMI interface 151 may include a plurality of HDMI ports, and the dongle and the set-top box may be connected via each HDMI port, respectively. In addition, the dongle may be connected to a USB port.

[0174] In this case, the processor 130 may display images received from external devices respectively connected to the HDMI interface 151 and the USB interface 152 on the display 110 , and output audio received from the external devices through the speaker 170 .

[0175] Furthermore, the interface 150 may include a component terminal, an optical terminal, an Ethernet terminal for connection with a local area network (LAN) cable, and the like.

[0176] The communication interface 160 may perform communication with an external device. Here, the communication interface 160 may include a Wi-Fi module 161 for Wi-Fi communication and a Bluetooth module 162 for Bluetooth communication.

[0177] The Wi-Fi module 161 may be connected to an access point, and access the Internet through the access point and perform communication with a server.

[0178] For example, the processor 130 may execute an application stored in the memory 180 according to a user command and access a server providing services through the application, and receive various data such as images and audio from the server through the Wi-Fi module 161 .

[0179] The Bluetooth module 162 may perform communication with a device located near the display device 100 .

[0180] For example, the processor 130 may control the Bluetooth module 162 so that the Bluetooth module 162 performs pairing with a device located around the display device 100. For example, an electronic device such as a remote controller may be communicatively connected to the electronic device.

[0181] In this case, if a control command is received from the electronic device through the Bluetooth module 162, the processor 130 may control the display device 100 according to the received control command.

[0182] For example, if a user command for rotating the display 110 is received from the electronic device through the Bluetooth module 162, the processor 130 may rotate the display 110 arranged in a horizontal direction to a vertical direction, or rotate the display 110 arranged in a vertical direction to a horizontal direction based on the received user command.

[0183] In addition, the communicator 160 may include a local area network (LAN) module. The LAN module may access the Internet through a LAN cable connected to an Ethernet terminal and perform communication with a server.

[0184] For example, the processor 130 may execute an application stored in the memory 180 according to a user command and access a server providing services through the application, and receive various data such as images and audios from the server through the LAN module.

[0185] When receiving an image, audio, etc. through the communication interface 160 , the processor 130 may display the received image on the display 110 and output the received audio through the speaker 170 .

[0186] The speaker 170 may output audio. Here, the processor 130 may output audio received from a dongle, a set-top box, a server, etc. through the speaker 170.

[0187] The memory 180 may store various instructions, software programs, applications, data, and the like related to the display device 100 .

[0188] Here, the processor 130 may execute one or more software programs stored in the memory 180 according to at least one instruction stored in the memory 180 and control the overall operation of the display device 100 .

[0189] like Figure 1A and Figure 1B As shown, a plurality of cameras 120 - 1 and 120 - 2 may be accommodated inside the display device 100 .

[0190] However, this is merely an example, and a device including multiple cameras (hereinafter, referred to as a dongle) may be connected to the display device 100 via the interface 150 of the display device 100, and the processor 130 may control the multiple cameras included in the dongle according to the direction in which the display 110 is arranged.

[0191] In this case, the dongle may include multiple cameras having different viewing angles from each other.

[0192] For example, the plurality of cameras may include a first camera that performs photographing by using a normal lens and a second camera that performs photographing by using a wide-angle (or ultra-wide-angle) lens having a larger angle of view than that of the normal lens.

[0193] For example, when the display 110 is arranged in a vertical direction, the processor 130 may send a control command for performing shooting through a first camera among the multiple cameras of the dongle to the dongle through the interface 150. In addition, when the display 110 is arranged in a horizontal direction, the processor 130 may send a control command for performing shooting through a second camera among the multiple cameras of the dongle to the dongle through the interface 150.

[0194] Furthermore, based on the tilt angle of the display 110 , the processor 130 may send a control command for rotating the camera of the dongle to the downward direction by as much as the tilt angle to the dongle through the interface 150 .

[0195] In addition, if it is determined that the user does not want to use the camera, the processor 130 may transmit a control command for covering a plurality of cameras to the dongle through the interface 150 .

[0196] Here, as an example, in a case where an application using the camera is not executed and the display 110 is arranged in a horizontal direction, the processor 130 may determine that the user does not want to use the camera.

[0197] Therefore, the dongle may perform an operation according to a control command received from the display apparatus 100 .

[0198] Fig. 9 is a block diagram showing a configuration of a dongle according to an embodiment.

[0199] Reference Fig. 9 , the dongle 200 may include a plurality of cameras 210 , an interface 220 , a communication interface 230 , a memory 240 , and a processor 250 .

[0200] Each of the plurality of cameras 210 may capture an image. Each of the cameras 210-1, 210-2 may include an image sensor and a lens, etc. Here, the number of cameras is not limited thereto, but may include more than two cameras.

[0201] The plurality of cameras 210-1 and 210-2 may have different viewing angles from each other. For example, the plurality of cameras 210 may include a first camera 210-1 that performs photographing by using a normal lens and a second camera 210-2 that performs photographing by using a wide-angle (or ultra-wide-angle) lens having a larger viewing angle than the normal lens.

[0202] In addition, the plurality of cameras 210 - 1 , 210 - 2 may be rotatable. That is, the dongle 200 may include a motor configured to rotate each of the cameras 210 - 1 , 210 - 2 or the like.

[0203] In this case, each camera 210-1, 210-2 can be rotated in the housing of the dongle 200 including the plurality of cameras 210-1, 210-2, respectively. In addition, when the dongle 200 is connected to the display device 100, the dongle 200 can be rotated in the vertical direction and the left-right direction.

[0204] The interface 220 may be connected with the display apparatus 100. As an example, the interface 220 may be connected with the display apparatus 100 by using various communication methods such as HDMI, USB, etc.

[0205] Specifically, the interface 220 may include an HDMI interface 221 and a USB interface 222, wherein the HDMI interface 221 includes an HDMI connector or an HDMI port for HDMI communication, and the USB interface 222 includes a USB connector or a USB port for USB 2.0 and / or USB 3.0 communication. In addition, the interface 220 may be directly connected to the display device 100, or connected to the display device 100 via a separate cable.

[0206] The communication interface 230 may perform communication with an external device. Specifically, the communication interface 230 may perform communication with an external device by using various communication methods such as mobile communication, Wi-Fi, Bluetooth, and the like.

[0207] The communicator 230 may include a mobile communication module 231 for mobile communications such as third generation (3G), third generation partnership project (3GPP), long term evolution (LTE), fifth generation (5G), etc., a Wi-Fi module 232 for Wi-Fi communication, and a Bluetooth module 233 for Bluetooth communication.

[0208] Specifically, the mobile communication module 231 can access the Internet through the mobile communication network and perform communication with the server, and the Wi-Fi module 232 can be connected to an access point and access the Internet through the access point and perform communication with the server. In addition, the Bluetooth module 233 can perform communication with devices located around the software dog 200.

[0209] The memory 240 may store various instructions and software programs related to the operation of the dongle 200, etc. The memory 240 may include a flash memory 241 and a RAM 242.

[0210] The processor 250 may control the overall operation of the dongle 200. That is, the processor 250 may be electrically connected to the plurality of cameras 210-1, 210-2, the interface 220, the communicator 230, and the memory 240, and control these components.

[0211] The processor 250 may include a central processing unit (CPU) or an application processor (AP). In addition, the processor 250 may execute one or more software programs stored in the memory 130 according to one or more instructions stored in the memory 240 .

[0212] For example, if power is applied to the dongle 200, the processor 250 may drive an operating system (OS) stored in the flash memory 241 by using the RAM 242. Here, the OS may be an OS used in portable devices such as smartphones, tablets, and the like, such as Android, and the like.

[0213] The power applied to the dongle 200 may be provided from the display device 100 connected to the dongle 200 through the USB interface 222. However, according to an embodiment, the dongle 200 may include a separate battery for supplying power.

[0214] Furthermore, the processor 250 may load an application stored in the flash memory 241 on the RAM 242 and execute the application through the OS.

[0215] Here, the application may be an application program executed based on the OS of the dongle 200. For example, in the case where the OS installed on the dongle 200 is Android, the application may be an application program executable in Android. In this case, the application may be stored in the memory 240 at the manufacturing stage of the dongle 200, or downloaded from a server providing the application (e.g., play store, etc.) according to a user command and stored in the memory 240.

[0216] Furthermore, the processor 250 may control various operations of the dongle 200 based on a control command received from the display apparatus 100 through the interface 220 .

[0217] Specifically, if a control command for performing photographing through the first camera 210 - 1 among the plurality of cameras 210 - 1 , 210 - 2 is received from the display device 100 , the processor 250 may perform photographing through the first camera 210 - 1 and transmit the photographed image to the display device 100 through the interface 220 .

[0218] In addition, if a control command for performing photographing through the second camera 210 - 2 among the plurality of cameras 210 - 1 , 210 - 2 is received from the display device 100 , the processor 250 may perform photographing through the second camera 210 - 2 and transmit the photographed image to the display device 100 through the interface 220 .

[0219] In addition, if a control command for rotating at least one of the multiple cameras 210-1, 210-2 in a downward direction at a specific angle (for example, the tilt angle of the display 110) is received from the display device 100, the processor 250 can rotate the camera in the downward direction at the received angle and send the image captured by the rotated camera to the display device 100 through the interface 220.

[0220] Furthermore, if a control command for covering the plurality of cameras 210 - 1 , 210 - 2 is received from the display device 100 , the processor 250 may cover the plurality of cameras 210 - 1 , 210 - 2 with the camera cover.

[0221] Here, the dongle 200 may include a camera cover for covering the plurality of cameras 210 - 1 , 210 - 2 , and thus, if a control command for covering the plurality of cameras is received, the processor 250 may drive the camera cover to cover the plurality of cameras 210 - 1 , 210 - 2 .

[0222] Fig.10 is a diagram illustrating a method of connecting a dongle to a display device according to an embodiment.

[0223] The dongle 200 can be connected to the display device 100. For example, Fig.10 As shown, the dongle 200 may be connected to the display 110 of the display device 100 at one side (eg, a vertical side) of the display 110 .

[0224] The display device 100 may provide a video call function by using a camera included in the dongle 200 .

[0225] For example, it may be assumed that a user is performing a video call with another user by using an electronic device (eg, a mobile phone).

[0226] Specifically, the user's first electronic device can send an image captured by a camera of the first electronic device and an audio received by a microphone of the first electronic device to another user's second electronic device (e.g., a mobile phone) through a server. Then, the first electronic device can receive the image and audio from another user's second electronic device through the server. Based on the communication with the second electronic device, the user's first electronic device can send the image and audio received from the second electronic device to the display device 100, and the display device 100 can output the received image and audio through a display and a speaker provided in the display device 100, respectively.

[0227] In this case, the display device 100 may perform a video call with another user's second electronic device using a camera included in the dongle 200 instead of the user's first electronic device. Here, a more detailed description will be given below.

[0228] Specifically, the user may execute an application for a video call installed on the first electronic device, log in through his or her user account, and perform a video call with a counterpart by using the logged in user account.

[0229] Here, if the first electronic device is within a predetermined distance from the display device 100 or contacts the display device 100 , the first electronic device may perform communication with the display device 100 by using a near field wireless communication (NFC) method.

[0230] Therefore, the first electronic device and the display device 100 may include NFC communication modules, respectively.

[0231] Therefore, the user's first electronic device can send information about the application used for the video call (e.g., identification information such as the name of the application, etc.) and information about the logged-in user account (e.g., ID and password, etc.) to the display device 100 by using a near-field wireless communication method.

[0232] Therefore, the processor 130 of the display device 100 may receive information about the application and information about the user account from the first electronic device.

[0233] In this case, the processor 130 can determine an application for video calling among at least one application installed on the display device 100 by using the received information about the application, and execute the determined application. Then, the processor 130 can perform login by using the received information about the user account, and receive images and audio from the other party's second electronic device through the server.
