     The display provided in the vehicle may be disposed on one area of a steering wheel, one area  251   a,    251   b,  and  251   e  of an instrument panel, one area  251   d  of a seat, one area  251   f  of each pillar, one area  251   g  of a door, one area of a center console, one area of a headlining, one area of a sun visor, one area  251   c  of a wind shield, one area  251   h  of a window or the like. 
     Moreover, the display may include a cluster, a center information display (CID), a navigation device, and a head-up display (HUD). 
     The display may form an inter-layer structure with the touch sensor or may be integrally formed to realize a touch screen. The touch screen functions as an input unit  210  that provides an input interface between the vehicle  100  (or the display control device  800 ) and the user and also provides an output interface between the vehicle  100  (or the display control device  800 ) and the user. 
       FIG.  10    is a flowchart for explaining a typical control method of the present disclosure. 
     The processor  830  of the display control device  800  of the present disclosure may receive information about a preset input applied to at least one of a plurality of displays provided in the vehicle (S 1010 ). 
     Afterwards, the processor  830  may control the plurality of displays so as to perform an operation corresponding to the preset input, in response to the preset input (S 1020 ). 
     In the present disclosure, in a multi-display environment where a plurality of displays is provided in a vehicle, portions of a screen to be displayed on each of a number of displays may be output separately, and one big, complete virtual display may be configured by bonding a number of displays together. 
     Moreover, in a multi-display environment, the present disclosure may output a small screen on a large display by using a mirroring or sharing function, or may perform multi-tasking with different screens. 
     Among them, the present disclosure may provide an environment for performing various types of sharing or collaboration, by using a mirroring or sharing function. 
     In a multi-display environment, the display control device of the present disclosure may include a multi-display manager. 
     Specifically, the multi-display manager may store location information for a physical location of each of a plurality of displays. The location information for a physical location of each of a plurality of displays may be set by the user when the display control device is mounted to the vehicle, or display device information stored in the manufacture of the vehicle may be received from the vehicle when the display control device is connected to the vehicle. 
     The display control device may include a gesture-based user interface. The gesture-based user interface may sense a user input (gesture) applied to at least one of the plurality of displays. 
     The display control device may include a display determination unit. 
     The display determination unit may determine which device a screen and audio are to be outputted, with respect to a device to which a user gesture is currently inputted, based on location information of the multi-display manager, and may transmit a display (source) providing an image and a display (destination) outputting a provided image to a multi-display buffer processor. 
     The multi-display buffer processor may be included in the display control device. 
     The multi-display buffer may receive a display (source) to which a user gesture is inputted and a display (destination) for sharing or mirroring video and audio being used, copies a screen and audio buffer of the source display in real time to a screen and audio buffer of the destination display, or replace the buffer of the destination display with the buffer of the source display to implement the sharing or mirroring function. 
     In a conventional multi-display environment, in order to share/mirror screens and audio between displays, it is necessary to perform the step 1) of searching and registering a connectable display and the step 2) of selecting a display to mirror or share, and most user interfaces are provided in the form of a list so that the user selects an identifier of a display they want to connect. 
     However, in the present disclosure, a multi-display manager within a system may store location information (device configuration information) for a physical location of each display, and based on this information, may share/mirror a screen intuitively by comparing it with the directionality of a user gesture. 
     To this end, the multi-display manager of the display control device  800  according to the present disclosure may store and manage a relative location (location information or device configuration information) of a display unit, and may include information on a location (e.g., front seat/back seat, left/center/right) where a display is installed in a multi-display environment for vehicles. 
     The gesture-based user interface may track the start/movement/end point of a user input (gesture) and determine the direction of the gesture. 
     For example, if the gesture is a touch gesture, the start point, movement path, and end point of the touch may be tracked to recognize the direction of the gesture. 
     As another example, if the gesture is a spatial gesture, a camera  820  for recognizing objects may be additionally provided, and the movement direction of an object (e.g., the user&#39;s hand) recognized through the camera  820  may be tracked to recognize the direction of the gesture. 
     The direction of the gesture may be simply divided into four directions: front, back, left, and right, or may be divided into eight directions: front, back, left, right, front left, front right, back left, and back right. 
     The display determination unit may determine gesture recognizing equipment as the source display (or source device), and determine the destination display (or destination device) based on the direction of the gesture. 
     The display determination unit may determine the source display and the destination display variously depending on whether a gesture is applied to the display, the installation location of the display, and the direction of the gesture, which will be described later. 
     The display determination unit may determine the source display which provides a screen/sound and the destination display which output the screen/sound provided by the source display, and may output the ID of the source display and the ID of the destination display. 
     The display buffer processor may periodically copy an output buffer of the source display to a buffer of the destination display, by using the ID of the source display and the ID of the destination display which are outputted from the display determination unit, or may change an ID buffer address of the destination display to an ID buffer address of the source display so that an image outputted from the source display is outputted equally on the destination display. 
     The above-described multi-display manager, gesture-based user interface, display determination unit, and display buffer processor may be implemented by the processor  830  of the display control device of the present disclosure. 
     The multi-display manager, the gesture-based user interface, the display determination unit, and the display buffer processor may be implemented as software components, or may be implemented as independent modules. 
     In the present disclosure, for convenience of explanation, a description will be given on the assumption that the processor  830  equally/similarly infers and applies operations/functions/control methods performed by the multi-display manager, the gesture-based user interface, the display determination unit, and the display buffer processor. 
       FIGS.  11    are  12  are conceptual diagrams for explaining an operating environment for a display control device of the present disclosure. 
     Referring to  FIG.  11   , a plurality of displays provided in the vehicle of the present disclosure may be controlled by a single OS (operating system) (e.g., a single Android OS) on a single SoC (System On Chip). 
     Moreover, the plurality of displays provided in the vehicle of the present disclosure may be run by different OSs (for example, the first display may be run on a Linux OS, and the second and third displays may be run on an Android OS). 
     In this case, as illustrated in  FIG.  11   , the display control device of the present disclosure may have a hypervisor so that compatibility is provided across different OSs on a single SoC. The display control device may perform data transmission/reception and sharing and/mirroring functions between different OSs through a hypervisor, even if displays provided in the vehicle are run on different OSs. 
     Referring to  FIG.  12   , the display control device of the present disclosure may be configured to control a plurality of displays on a single SoC, and to this end, system control software SW may be installed. 
     Among the plurality of displays provided in a vehicle of the present disclosure, the first display  910  may be installed in a position where the driver can manipulate it, and all applications (game, navigation, map, image, web, etc.) that can be run on the plurality of displays  910 ,  920 , and  930  may be run. 
     Each of the plurality of displays in the present disclosure may have a buffer for loading and storing from a memory or an external server in advance, in order to play back screen information to be outputted from each display without buffering. 
     Upon a request for a screen sharing or mirroring function between displays by a user input (gesture), the display control device may control a buffer related to each display and resize screen information being outputted from a source display and load resized screen information to a buffer of a destination display so as to output it on the destination display. 
     Afterwards, the display control device may load the resized screen information to the buffer of the destination display and output it on the destination display. 
     In other expressions, when the user requests a screen of another display (requested display) from a particular display device (requesting display) by PIP, control SW (operating system) installed on the display control device may 1) access a display video buffer of the requested display device (Access Controller), 2) resize the content of the display video buffer of the requested display device (buffer resizer), 3) reflect the contents of the display video buffer of the resized requested display device to a specific area of the video buffer of the requesting display device (video buffer modifier), and 4) perform periodical update so that the requesting display device monitors a screen being outputted on the requested display in real time. 
     Through this, in the present disclosure, each display has a video buffer, and a screen running on each display device is independently outputted to the video buffer so that each display device is used as an independent device. When the user requests to monitor a screen of another display device in PIP form, the system control SW (operating system) additionally enables the following functions for the existing display buffer management to 1) access a display video buffer of the requested display device (Access Controller), 2) resize the content of the display video buffer of the requested display device (buffer resizer), 3) reflect the contents of the display video buffer of the resized requested display device to a specific area of the video buffer of the requesting display device (video buffer modifier), and 4) perform periodical update so that the requesting display device monitors a screen being outputted on the requested display in real time. 
     That is, the display control device of the present disclosure may include system control software, a display access controller, a buffer resizer, and a video buffer modifier. 
     The display access controller may 1) allocate a video buffer to each display to output a screen of an app running on each display in real time if the user has not requested a monitoring function using a PIP function and 2) have access to the video buffer of the requested display if the user has requested a monitoring function using a PIP function. 
     The buffer resizer may perform a function of resizing the content of the video buffer of a particular display to a small size in response to a request from the display access controller. 
     The video buffer modifier may perform a function of synthesizing resized requested contents provided by the buffer resizer with the video buffer of the requesting device. 
     In the present disclosure, when the user has requested a monitoring function using a PIP function from a particular display device, the system control S/W accesses the video buffer of the requested device through the display access controller, reduces the contents of the video buffer of that display by using the buffer resizer, and synthesizes the resized screen of the requested display with the video buffer for the requesting display by using the video buffer modifier to monitor a screen being run on the requested display in real time. 
     Moreover, in the present disclosure, only a user with a particular right may make a screen monitoring request using a corresponding PIP function. 
     According to an embodiment of the present disclosure, parents may monitor a screen being outputted on a display device their child is using in real time (for the purpose of blocking inappropriate services or content), and the driver may monitor a screen being outputted on the back seat in a vehicle environment. 
     The above-explained system control software, display access controller, buffer resizer, and video buffer modifier may be implemented by the processor  830  of the display control device of the present disclosure. 
     Hereinafter, a method in which a display control device of the present disclosure shares and/or mirrors a screen intuitively and effectively from a plurality of displays provided in a vehicle will be described in more details with reference to the accompanying drawings. 
       FIGS.  13 ,  14 ,  15 ,  16 ,  17 ,  18 ,  19 ,  20 ,  21 ,  22 ,  23 ,  24 , and  25    are conceptual diagrams for explaining a display control method according to various embodiments of the present disclosure. 
     The display control device of the present disclosure may control displays  251  (hereinafter, three displays  910 ,  920 , and  930 , for example) provided in a vehicle through the interface unit  810  (or communication unit). 
     In this case, the processor  830  may receive information about a preset input applied to at least one of a plurality of displays provided in a vehicle from a display unit or the controller  170 . 
     The information about the preset input may include user input-related information the user has inputted into a display, such as the type of user input (gesture), the start and end points of the user input, and the direction in which the user input is applied. 
     Upon receiving information about the preset input, the processor  830  may determine that a user input has applied to at least one of a plurality of displays provided in the vehicle. 
     In response to the preset input, the processor  830  may control the plurality of displays so that an operation corresponding to the preset input is performed. 
     The processor  830  may perform an operation corresponding to the preset input based on information on locations where the plurality of displays is provided (installed). 
     For example, the first display  910  may be installed at a position where it can be manipulated from the front seat in the vehicle, the second display  920  may be installed at a position where it can be manipulated from the left side of the back seat, and the third display  930  may be installed at a position where it can be manipulated from the right side of the back seat. 
     The installation positions of the first to third displays may be included in the location information, and the location information (or the above-described device configuration information) may be generated/determined or varied by user settings. 
     Moreover, the location information may be prestored in the vehicle when the vehicle is manufactured or when the plurality of displays are installed in the vehicle, and may be sent to the display control device from the vehicle in accordance with a request from the display control device. 
     The preset input may include various types of user inputs. 
     Here, the preset type of user input may include a touch input applied to the displays  251  or a user input applied to a user interface device (e.g., a button, jog dial, knob, etc. provided on the steering wheel) related to each display. 
     The preset type of user inputs may include various types of touches. For example, the various types of touches may include a short (or tap) touch, a long touch, a double touch, a multi touch, a drag touch, a flick touch, a pinch-in touch, a pinch-out touch, a swipe touch, a hovering touch and the like. 
     Hereinafter, the various types of touches will be described in more detail. 
     The short (or tap) touch may be a touch that a touch object, namely, an object to apply a touch, (e.g., a finger or a stylus pen) is released within a predetermined time after coming in contact with the display  251  (after a touch is applied). For example, the short (or tap) touch may be a touch that the touch object contacts the display  251  for a short time, like a single click of a mouse. 
     The long touch may be a touch that the touch object which has come in contact with the display  251  is maintained in the contact state for a predetermined time or longer. For example, the long touch may be a touch that is applied onto the display  251  by the touch object and then is maintained for more than a predetermined time. More concretely, the long touch may be a touch that is released after being continuously in a contact with on one point of the touch screen for more than a predetermined time. Also, the long touch may be understood as a touch corresponding to a touch and hold operation that the contact state of the touch object on the display  251  is held for more than a predetermined time. 
     The double touch may be a touch that a short touch is consecutively applied onto the display  251  at least two times within a predetermined time. 
     The predetermined time which is described in the short touch, the long touch and the double touch may be decided by user setting. 
     The multi-touch may be a touch that is applied onto at least two contact points of the display  251  substantially at the same time point. 
     The drag touch may be a touch that a contact which has started from a first point of the display  251  is continuously applied on the touch screen along one direction and then released on a second point different from the first point. 
     In more detail, the drag touch may be a touch that is applied to one point of the display  251  by a touch object, continuously extends on the display  251  and then is released at another point different from the one point. 
     Also, the drag touch may also refer to a touch which continuously extends from a touch applied onto one point of the display  251 . 
     The flick touch may be a touch that the drag touch is applied within a predetermined time. In more detail, the flick touch may be a touch that a touch object which applies the drag touch is released from the display  251  within a predetermined time. In other words, the flick touch may be understood as a drag touch that is applied at a preset speed or more. 
     The swipe touch may be a drag touch applied along a straight line. 
     The pinch-in touch may be a touch that at least one of first and second touches applied to two different points (two points spaced from each other) on the display  251  extend to be close to the other or each other. For example, the pinch-in touch may be a touch that is realized by an operation of narrowing a gap between fingers while the fingers contact two different points spaced apart from each other on the display  251 . 
     The pinch-out touch may be a touch that at least one of first and second touches applied to two different points (two points spaced from each other) on the display  251  extend to be away from the other or each other. For example, the pinch-out touch may be a touch corresponding to an operation of spacing fingers farther away from each other while the fingers contact two different points spaced from each other on the display  251 . 
     The hovering touch may be a touch corresponding to an operation of a touch object at a space apart from the display  251  without touching the display  251 . As one example, the hovering touch may be a proximity touch. For example, the hovering touch may be a touch corresponding to an operation that the touch object is held above one point, spaced from the display  251 , for a predetermined time or more. 
     The force touch refers to a touch in which the touch target applies a pressure higher than a predetermined pressure to the display  251 . 
     Also, the above-described various types of touches may be inferred/applied equally/similarly to a user input applied to a user interface device. 
     Moreover, the preset input may include a user gesture applied while not directly touching the display, and the user gesture may infer/apply the above-described various touch methods equally/similarly. 
     When a user input is applied as a user gesture which is made in a space spaced a predetermined distance from the display, the display control device may recognize the user gesture through a camera installed near (or stacked on) each display. 
     The preset input may include an input that is applied in a certain direction from one point and then released at another point. For example, the preset input may be implemented as a drag input, a flick input, or a swipe input which has directionality. 
     The preset input may be recognized as a sharing request gesture when screen sharing is dome, or as a sharing release request gesture when screen sharing is not done. 
     The processor  830  may control the plurality of displays so as to perform an operation corresponding to the preset input, based on at least either the positions of the plurality of displays, the display where the preset input is applied, or the certain direction in which the preset input is applied. 
     Here, when the preset input is applied to the at least one display, the processor  830  may switch the screen of another display positioned in the direction in which the preset input is applied, based on location information of the plurality of displays. 
     For example, as illustrated in (a) of  FIG.  13   , different screens may be outputted on the plurality of displays  910 ,  920 , and  930 . 
     For example, first screen information (B) is being outputted on the first display  920 , among the plurality of displays, and second screen information (c) is being outputted on the second display  930  different than the first display. 
     The processor  830  may control the second display  930  so as to output the first screen information (B) being outputted on the first display to the second display  930  positioned in the first direction (right) with respect to the first display, as illustrated in (c) of  FIG.  13   , based on reception of a swipe input applied to the first display  920  in the first direction (e.g., right). 
     That is, when a swipe input is applied to the right of the first display  920 , a screen being outputted on the first display  920  may be shared with (copied or mirrored onto) the second display  930  on the right side of the first display  920 . 
     Accordingly, substantially the same screen B may be outputted on the first display  920  and the second display  930 , based on reception of the swipe input. 
     Even if the manufacturers, screen sizes, picture quality, etc. of the first and second displays are different, the source of the screen information being outputted may be substantially the same. Thus, the screen information being outputted on the first and second displays may be substantially the same. 
     Afterwards, upon receiving a swipe input applied to the first display  920  corresponding to the source display in a second direction (left) opposite to the first direction (right), while the screen is being shared, as illustrated in (d) of  FIG.  13   , or upon receiving a swipe input applied to the second display  930  corresponding to the destination display, in the second direction (left) opposite to the first direction (right) as illustrated in (e) of  FIG.  13   , the first screen information (B) being outputted on the second display  930  may be restored (switched) to the second screen information (c) which was being outputted before the sharing. 
     Meanwhile, when the preset input is applied to the at least one display, the display control device  800  according to the present disclosure may switch a screen of another display positioned in a direction opposite to the direction in which the preset input is applied, based on location information of the plurality of displays. 
     As illustrated in (a) of  FIG.  14   , first screen information (C) is being outputted on a first display  930 , and second screen information (B) is being outputted on a second display  920  which is positioned in a first direction (e.g., left) of the first display. 
     As illustrated in (b) and (c) of  FIG.  14   , the processor  830  may control the first display  930  so that second screen information (B) being outputted on the second display  920  is outputted on the first display  930 , based on reception of a swipe input on the first display  930 , in a second direction (right) opposite to the first direction (left). 
     Afterwards, as illustrated in (d) and (e) of  FIG.  14   , upon receiving a swipe input applied to the first display  930  or the second display  920 , in the first direction (left) opposite to the second direction (right), the processor  830  may restore the second screen information (B) being outputted on the first display  930  to the first screen information (C). 
     Unlike  FIG.  13   , in  FIG.  14   , a display to which a preset input is applied serves as a destination display, and a display positioned in a direction opposite to the direction in which the preset input is applied serves as a source display. 
     This means that a display to which the preset input is applied and a display that switches between screens according to the direction in which the preset input is applied (that is, the source display and the destination display) may be set differently. 
     Specifically, the processor  830  may determine a display whose screen is to be switched, based on the direction in which the preset input is applied and the position of the display to which the preset input is applied. 
     When the preset input is applied to a certain display in one direction, if there is another display in one direction of the certain display, the processor  830  may switch a screen of the another display. 
     That is, when a preset input is applied to a certain display in one direction, if there is another display in the one direction of the certain display, the processor  830  may set the display to which the preset input is applied as the source display, and set the another display present in the one direction as the destination display whose screen is to be switched (corresponding to  FIGS.  13  and  16   ). 
     On the other hand, when the preset input is applied to a certain display in one direction, if there is no other display in one direction of the certain display, the processor  830  may switch a screen of the certain display (corresponding to  FIGS.  14  and  15   ). 
     For example, as illustrated in  FIG.  15   , when a preset input is applied to a certain display  920  in one direction (e.g., leftward), if there is no other display in the one direction (left) of the certain display  920 , the certain display  920  may be set as the destination display, and the another display  930  present in a direction (right) opposite to the one direction (left) of the certain display may be set as the source display. 
     Accordingly, as illustrated in (b) and (c) of  FIG.  15   , when a preset input is applied to a certain display  920  in one direction (left), if there is another display in the one direction of the certain display  920 , the processor  830  may output screen information (C) being outputted on the display  930 , which is opposite to the one direction, on the certain display  920 . 
     This may be understood as an operation in which the certain display pulls the screen (C) of another display and shares it. 
     Afterwards, upon receiving a preset input in a direction (right) opposite to the one direction on the certain display and another display, the sharing function may be disabled, and the screen of the certain display  920  may be restored to the original screen (B). 
     In  FIG.  16   , as explained previously, when the preset input is applied to a certain display in one direction, if there is another display in the one direction of the certain display, the processor  830  may switch the screen of the another display. 
     For example, as illustrated in (b) and (c) of  FIG.  16   , when a preset input is applied to a certain display  930  in one direction (e.g., leftward), if there is another display  920  in the one direction (e.g., leftward) of the certain display  930 , the another display may be set as the destination display, the certain display may be set as the source display, and the screen of the another display may be switched to a screen (C) of the certain display. 
     Afterwards, when a preset input is applied in a direction (e.g., rightward) opposite to the one direction on the certain display  930  or another display  920 , the processor  830  may disable the sharing function and restore (switch) the screen of the another display  920  to the original screen (B). 
     In the case of  FIGS.  13  and  14    explained previously, it can be inferred/applied equally and similarly that a display whose screen is to be switched may be determined based the direction in which a preset input is applied and the position of the display to which the preset input is applied. 
     Meanwhile, the above description may be inferred/applied equally/similarly to both front and back displays. 
     As illustrated in (b) of  FIG.  17   , when a preset input is applied in one direction (e.g., back) on a certain display  910 , the processor  830  may output screen information A being outputted on the certain display  910  on another display  920  positioned in the one direction. 
     This can be understood that screen information being outputted on a certain display  910  is shared with another display  920  present in the direction in which the preset input is applied. 
     Afterwards, as illustrated in (d) and (e) of  FIG.  17   , when a preset input is applied to a certain display  910  or another display  920  (the source display or the destination display) in a direction opposite to the one direction, the processor  830  may switch the screen being shared with the another display  920  to the original screen (B). 
     Although not shown, when a preset input is applied in one direction (e.g., backward) on a certain display  910 , if there is a plurality of displays  920  and  930  in the one direction with respect to the certain display, the processor  830  may switch all of the plurality of displays  920  and  930  to screen information (A) being outputted on the certain display  910 . 
     In this case, when an input of a type different than that of the preset input illustrated in  FIG.  17    (e.g., a drag touch with two fingers in this embodiment, whereas one finger in the case of  FIG.  17   ) is applied, the processor  830  may switch (share) all of the plurality of displays to a screen being outputted on a certain display. 
     Also, as illustrated in (b) and (c) of  FIG.  18   , when a preset input is applied in one direction (e.g., backward) on a certain display  920 , if there is no other display in the one direction with respect to the certain display  920 , the processor  830  may have a screen shared by another display  910  positioned in a direction (front) opposite to the one direction, and output screen information (A) being outputted on the another display  910  to the certain display  920 . 
     Afterwards, upon receiving a preset input in a direction opposite to the one direction on the certain display  920  or another display  910 , while the screen is being shared, the processor  830  may restore the screen being outputted on the certain display  920  to the original screen (B). 
     What has been described with reference to  FIG.  18    may be inferred/applied equally/similarly to  FIG.  19   . 
     Also, as illustrated in (b) and (c) of  FIG.  19   , when a preset input is applied in one direction (e.g., backward) on a certain display  930 , if there is no other display in the one direction with respect to the certain display  930 , the processor  830  may have a screen shared by another display  910  positioned in a direction (front) opposite to the one direction and output screen information (A) being outputted on the another display  910  to the certain display  930 . 
     If there is any other display (not shown) on the right side of the another display  910  and the front side of the certain display  930 , the processor  830  may share and output an output screen of the any other display on the certain display  930 . 
     On the other hand, if there is no other display in the direction in which the preset input is applied with respect to the display to which the preset input is applied, the certain display  930  may have a screen shared by the another display  910  present in the opposite direction. 
     Meanwhile, as illustrated in (b) and (c) of  FIG.  20   , if there are at least two displays in the opposite direction (back) of the direction (front) in which the preset input is applied, screen information (B, C) being outputted on the at least two displays  920  and  930  may be outputted on the display  910  to which the preset input is applied. 
     In this case, as illustrated in (c) of  FIG.  20   , the screen information (B, C) being outputted on the at least two displays may overlap the screen information (A) being outputted on the display  910  to which the preset input is applied. 
     On the other hand, as illustrated in (d), when a preset input is applied in a direction (e.g., back) opposite to the one direction on the certain display  910  or the at least two displays, the processor  830  may disable the sharing function, and control the certain display  910  so that the screen information (B, C) being outputted on the at least two displays disappear from the certain display. 
     Meanwhile, the display control device of the present disclosure may perform communication with a plurality of cameras provided in the vehicle, and may output images received through the cameras on a display in an optimized manner. 
     The interface unit  810  (or communication unit) provided in the display control device of the present disclosure may be configured to receive images from a plurality of cameras A, B, C, and D provided in the vehicle. 
     Based on a direction in which the preset input (e.g., a swipe, drag, or flick input with a directionality) is applied to a display provided in the vehicle, the processor  830  may receive images from different cameras and output the images to the display to which the preset input is applied. 
     Referring to  FIG.  21   , as illustrated in (a) of  FIG.  21   , when a preset input is applied to the display in a first direction (right), the processor  830  may receive an image  2200   b  from a first camera (Camera B) installed at a position (left) opposite to the direction, among the plurality of cameras, and displays the image on the display, as illustrated in (b) of  FIG.  21   . 
     As illustrated in (a) of  FIG.  22   , when a preset input is applied to the display in a second direction (left) different from the first direction (right), the processor  830  may receive an image  2200   c  from a second camera (Camera C) installed at a position (right) opposite to the second direction (left), among the plurality of cameras, and output the image on the display, as illustrated in (c) of  FIG.  22   . 
     The position opposite to the first direction may refer to a position that indicates a direction opposite to the first direction. Also, the position opposite to the first direction may be represented as a position opposed to the first direction, and if the first direction is the right side, the position opposed to the first direction may refer to the left side with respect to the vehicle. 
     The position opposite to the second direction may refer to a position that indicates a direction opposite to the second direction. Also, the position opposite to the second direction may be represented as a position opposed to the first direction, and if the second direction is the left side, the position opposed to the second direction may refer to the right side with respect to the vehicle. 
     As illustrated in (c) of  FIG.  21   , when a preset input is applied in a direction (left) opposite to the first direction (right), while the image  2200   b  received through the camera is being outputted on the display, the processor  830  may stop image transmission from the camera (Camera B) and output originally outputted screen information  2100  on the display, as illustrated in (d) of  FIG.  21   . 
     Likewise, as illustrated in (c) of  FIG.  22   , when a preset input is applied in a direction (right) opposite to the second direction (left), while the image  2200   c  received through a camera is being outputted on the display, the processor  830  may stop image transmission from the camera (Camera C) and output the originally outputted screen information  2100  on the display, as illustrated in (d) of  FIG.  22   . 
     Meanwhile, upon receiving a preset input of a first type, the processor  830  may switch the screen  2100  being outputted on the display to the image transmitted from the camera, as illustrated in (a) and (b) of  FIG.  21    and (a) and (b) of  FIG.  22   . 
     On the other hand, upon receiving a preset input of a second type different from the first type, the processor  830  may output the image  2200   b  transmitted from the camera in such a way as to overlap some region of the display, as illustrated in (b) of  FIG.  22   . 
     In this case, although not shown, the processor  830  may set (determine) some region of the display where an image transmitted from a camera is outputted, based on a direction in which the preset input of the second type is applied. 
     For example, if the direction in which the preset input of the second type is applied is a first direction (e.g., right), the processor  830  may output the image  2200   b  received from a camera (Camera B) present at a position opposite to the first direction in some region of the display present in a direction (e.g., left) opposite to the first direction. 
     As another example, if the direction in which the preset input of the second type is applied is a second direction (e.g., left) different from the first direction, the processor  830  may output the image  2200   c  received from a camera (Camera C) present at a position opposite to the second direction in some region of the display present in a direction (e.g., right) opposite to the second direction. 
     On the other hand, upon receiving a preset input of a third type different from the first and second types, the processor  830  may reduce the screen  2100  being outputted on the display and output the reduced screen  2100  in such a way as to overlap the image  2200   b  transmitted from the camera, as illustrated in  FIG.  24   . 
     In this case, the processor  830  may output the reduced screen at different positions, based on the direction in which the preset input of the third type is applied. Also, the processor  830  may receive different images from different cameras, based on the direction in which the preset input of the third type is applied. 
     For example, as illustrated in  FIG.  24   , if the direction in which the preset input of the third type is a first direction (e.g., right), a first image  2200   b  may be received from a camera (Camera B) present at a position opposite to the first direction and output it on the display unit, and may reduce and output the screen  2100  being outputted on the display at the position (left side) opposite to the first direction. 
     For example, as illustrated in  FIG.  25   , if the direction in which the preset input of the third type is applied is a second direction (e.g., left), a second image  2200 C may be received from a camera (Camera C) present at a position opposite to the second direction and output it on the display unit, and may reduce and output the screen  2100  being outputted at a position (right) opposite to the first direction.
