     EXAMPLE EMBODIMENT 
     Example embodiments of the present invention will be described hereinafter with reference to the drawings. The same or corresponding elements are denoted by the same reference symbols throughout the drawings, and redundant descriptions will be omitted as necessary for the clarification of the description. 
     First Example Embodiment 
     The configuration of a remote monitoring and control apparatus and a system according to a first example embodiment will be described. 
       FIG.  1    is a block diagram illustrating the remote monitoring and control apparatus according to the first example embodiment. 
       FIG.  2 A  is a block diagram illustrating the system according to the first example embodiment. 
       FIG.  2 B  is a block diagram illustrating the system according to the first example embodiment. 
     In the first example embodiment, the technology of the present disclosure will be described with reference to an example in which a vehicle is driven automatically. Further, in the first example embodiment, the remote monitoring and control apparatus installed in a monitoring center remotely monitors and controls a vehicle which is a mobile body. However, in the following description, the monitoring center remotely monitors and controls a vehicle. Note that examples of the mobile body include at least one of a vehicle including an automobile, a railway, and the like, an aircraft, and a ship. Further, the monitoring center may be referred to as a control center. 
     As shown in  FIGS.  1 ,  2 A, and  2 B , a system  10  according to the first example embodiment includes an information acquisition device  12 , a determination device  13 , and a monitoring center  11 C. A remote monitoring and control apparatus  11  is installed in the monitoring center  11 C. 
     As shown in  FIG.  2 A , the information acquisition device  12  includes a sensor  121  and a camera  122 . The sensor  121  acquires sensor data indicating information about a traveling state of a vehicle. The camera  122  acquires video image data captured from the vehicle in a direction external thereto. 
     The determination device  13  includes data acquisition means  131 , autonomous driving determination means  132 , and communication means  133 . The determination device  13  may implement the functions of the data acquisition means  131 , the autonomous driving determination means  132 , and the communication means  133  by using a cloud connected to a communication network. 
     The data acquisition means  131  may acquire sensor data, image data, and the like obtained by a traffic signal or a sensor such as a camera provided near the traffic signal through the traffic signal or communication means provided near the traffic signal. Further, the data acquisition means  131  may acquire sensor data and video image data using, for example, communication means such as 5 Generation (5G), Long Term Evolution (LTE), and Wi-Fi (registered trademark). The video image data may be referred to as moving image data. 
     The autonomous driving determination means  132  determines whether or not the vehicle is able to perform autonomous driving based on sensor data acquired from the information acquisition device  12 . The determination as to whether or not the vehicle is able to perform autonomous driving may be made using Artificial Intelligence (AI). Further, each vehicle may include AI mounted thereon, whereby, by using the AI, the determination as to whether or not the vehicle is able to perform autonomous driving may be made for each vehicle. 
     Further, the determination as to whether or not the vehicle is able to perform autonomous driving may be made so that the vehicle can be classified into, for example, the following three classes: a vehicle that is not able to perform autonomous driving, a vehicle that is highly unlikely to be able to perform autonomous driving, or a vehicle that is able to perform autonomous driving. 
     Further, the determination as to whether or not the vehicle is able to perform autonomous driving may be made in accordance with the type of danger to the vehicle and a possibility that the danger to the vehicle has occurred based on sensor data indicating information about a traveling state of the vehicle. 
     The communication means  133  transmits a result of the determination regarding the vehicle performed by the autonomous driving determination means  132  to the monitoring center  11 C. 
     As shown in  FIGS.  1  and  2 B , the monitoring center  11 C includes determination result acquisition means  111 , display means  112 , and control means  113 . 
     The determination result acquisition means  111  acquires, from the determination device  13 , a result of the determination indicating whether or not the vehicle is able to perform autonomous driving performed by the autonomous driving determination means  132  of the determination device  13 . 
     The display means  112  can display a monitor screen  112   a  and a remote control screen  112   b . The monitor screen  112   a  displays video image data captured by the camera  122  for each of a plurality of vehicles. The monitor screen  112   a  is a screen for a person who performs monitoring to monitor vehicles. That is, the person who performs monitoring monitors the vehicles by using the monitor screen  112   a.    
     The video image data displayed on the monitor screen  112   a  and the remote control screen  112   b  is not limited to the video image data captured by the camera  122 . The video image data displayed on the monitor screen  112   a  and the remote control screen  112   b  may be video image data (images) obtained by processing video image data of the vehicle and its surroundings captured by the camera  122 . 
     The remote control screen  112   b  displays video image data of a remotely controlled vehicle selected from among a plurality of vehicles. The remote control screen  112   b  is a screen for a person who performs monitoring to remotely control a vehicle. That is, the person who performs monitoring remotely controls (automatically drives) a vehicle by using the remote control screen  112   b . The display means  112  displays at least one of the monitor screen  112   a  and the remote control screen  112   b . The remote control screen may be referred to as a remote driving screen or a remote operation screen. Further, the display means  112  may display both the monitor screen  112   a  and the remote control screen  112   b.    
     When it is determined that a predetermined vehicle among the plurality of vehicles is not able to perform autonomous driving, the control means  113  selects the predetermined vehicle as a remotely controlled vehicle. The control means  113  displays video image data of the predetermined vehicle on the remote control screen  112   b . At this time, the remote control screen  112   b  is displayed in a more emphasized manner than that of the monitor screen  112   a . The control means may be referred to as display changing means. 
     For example, the control means  113  may make the size of the remote control screen  112   b  larger than that of the monitor screen  112   a , thereby displaying the remote control screen  112   b  in a more emphasized manner than that of the monitor screen  112   a.    
     The control means  113  may make the size of the remote control screen  112   b  larger than that of the monitor screen  112   a  by a predetermined trigger. 
     When the determination device  13  determines that the predetermined vehicle is not able to perform autonomous driving, a video image captured from the predetermined vehicle in the direction to the front is required since a person who performs monitoring remotely controls the vehicle by using the remote control screen  112   b . Therefore, video image data includes at least video image data captured from the vehicle in the direction in which the vehicle travels, that is, in the direction to the front of the vehicle. 
     Operations performed by the monitoring center according to the first example embodiment will be described. 
       FIG.  3    is a flowchart illustrating operations performed by the monitoring center according to the first example embodiment. 
     As shown in  FIG.  3   , the monitoring center  11 C acquires a result of determination as to whether or not the vehicle is able to perform autonomous driving (Step S 101 ). 
     If it is determined that a predetermined vehicle among a plurality of vehicles is not able to perform autonomous driving (Step S 102 : Yes), the monitoring center  11 C selects the predetermined vehicle as a remotely controlled vehicle (Step S 103 ). 
     The monitoring center  11 C displays video image data of the selected predetermined vehicle on the remote control screen  112   b . At this time, the remote control screen  112   b  is displayed in a more emphasized manner than that of the monitor screen  112   a  (Step S 104 ). 
     If it is not determined in Step S 102  that the predetermined vehicle is not able to perform autonomous driving (Step S 102 : No), the monitoring center  11 C checks whether or not it is highly unlikely that the predetermined vehicle will be able to perform autonomous driving (Step S 105 ). 
     If it is determined that it is highly unlikely that the predetermined vehicle will be able to perform autonomous driving (Step S 105 : Yes), the monitoring center  11 C performs Step S 103 . 
     If it is determined in Step S 105  that it is not highly unlikely that the predetermined vehicle will be able to perform autonomous driving (Step S 105 : No), the monitoring center  11 C displays the monitor screens  112   a  of the plurality of vehicles on the display means (Step S 106 ). 
     After Steps S 104  and S 106 , the monitoring center  11 C checks whether or not to end the remote control or the autonomous driving (Step S 107 ). 
     If the monitoring center  11 C does not end the remote control or the autonomous driving (Step S 107 : No), the process returns to Step S 102 . The monitoring center  11 C controls display means  212  as described in Steps S 101  to S 107 . 
     When it is determined that a predetermined vehicle is not able to perform autonomous driving, the monitoring center  11 C according to the first example embodiment displays, on the remote control screen  112   b , video image data captured from the predetermined vehicle in a direction external thereto. At this time, the monitoring center  11 C displays the remote control screen  112   b  in a more emphasized manner than that of the monitor screen  112   a . As a result, since video image data of the predetermined vehicle which it is determined is not able to perform autonomous driving and which requires automated driving is displayed in a more emphasized manner, a person who performs monitoring can check the video image data of the predetermined vehicle on the remote control screen  112   b  without having to perform any operation. The person who performs monitoring (the remote driver) can then focus on remotely controlling the predetermined vehicle. In this way, the person who performs monitoring can easily perform remote control of a predetermined vehicle required to be remotely controlled while monitoring a plurality of vehicles. 
     As a result, according to the first example embodiment, it is possible to provide a remote monitoring and control apparatus, a system, a method, and a non-transitory computer readable medium storing a program that are capable of improving the monitoring efficiency of a mobile body (a vehicle) when the mobile body (the vehicle) is remotely monitored and controlled. 
     Note that, in the first example embodiment, the operations performed when the determination device  13  determines that a predetermined vehicle is not able to perform autonomous driving have been described, and operations similar to these operations may be performed when it is highly unlikely that the predetermined vehicle will be able to perform autonomous driving. That is, the control means  113  may display video image data of a vehicle which it is highly unlikely will be able to perform autonomous driving on the remote control screen  112   b  in an emphasized manner. 
     Further, among the monitor screens  112   a  of a plurality of vehicles, the monitor screen  112   a  on which video image data of the vehicle which it is determined is not able to perform autonomous driving or which it is highly unlikely will be able to perform autonomous driving is displayed may be emphasized. 
     Note that, in the first example embodiment, although a description has been given in accordance with the assumption that the autonomous driving determination means  132  of the determination device  13  is provided outside the monitoring center  11 C, the present disclosure is not limited thereto. The autonomous driving determination means  132  may be provided inside the monitoring center  11 C. That is, the monitoring center  11 C may include autonomous driving determination means for determining whether or not the vehicle is able to perform autonomous driving based on sensor data indicating information about a traveling state of the vehicle. 
     Further, in the first example embodiment, although an example of a case in which a vehicle is monitored and then driven automatically has been described, the present disclosure is not limited thereto. The technology of the present disclosure may be applied not only to the automated driving of a vehicle but also, for example, to the monitoring of road conditions of expressways or the operation management of bullet trains. 
     Further, in the first example embodiment, although a case has been described in which the display means  112  includes a monitor display for displaying the monitor screen  112   a  and a remote control display for displaying the remote control screen  112   b , the present disclosure is not limited thereto. The display means  112  may include one display and display the monitor screen  112   a  and the remote control screen  112   b  on this display. Further, the display means  112  may include three or more displays. 
     Second Example Embodiment 
       FIG.  4    is a block diagram illustrating a system according to a second example embodiment. 
     In  FIG.  4   , autonomous driving determination means  232  is provided inside a monitoring center  21 C. 
     As shown in  FIG.  4   , a system  20  according to the second example embodiment differs from the system  10  according to the first example embodiment in that the autonomous driving determination means  232  is provided inside the monitoring center  21 C. 
     When the autonomous driving determination means  232  determines that a predetermined vehicle among a plurality of vehicles is not able to perform autonomous driving, control means  213  of the monitoring center  21 C according to the second example embodiment switches the display means  212  from the monitor screen  212   a  on which video image data of the plurality of vehicles are displayed to the remote control screen  212   b  on which video image data of the predetermined vehicle is displayed. By doing so, it is possible to display the remote control screen  212   b  in a more emphasized manner than that of the monitor screen  212   a.    
     Further, the control means  213  may perform switching between the monitor screen  212   a  and the remote control screen  212   b  by a predetermined trigger. The control means may be referred to as display switching means. 
     Note that, in the second example embodiment, although a description has been given in accordance with the assumption that the autonomous driving determination means  232  is provided inside the monitoring center  11 C, the present disclosure is not limited thereto. The autonomous driving determination means  132  may be provided inside a vehicle (as indicated by a dotted line in  FIG.  4   ) instead of being provided inside the monitoring center  11 C. 
       FIG.  5    is a block diagram illustrating the system according to the second example embodiment. 
       FIG.  5    shows details of the system  20  according to the second example embodiment. 
     As shown in  FIG.  5   , when the autonomous driving determination means  232  determines that a predetermined vehicle among a plurality of vehicles to be monitored is not able to perform autonomous driving, the control means  213  switches the display means  212  from the monitor screen  212   a  to the remote control screen  212   b  (the remote driving screen) of the predetermined vehicle. At this time, as indicated by an arrow Y 1  in  FIG.  5   , switching is performed on the same display means (the same screen). 
     Further, when the autonomous driving determination means  232  determines that a predetermined vehicle among a plurality of vehicles to be monitored is not able to perform autonomous driving, the control means  213 , as indicated by an arrow Y 2  in  FIG.  5   , may display video image data of the predetermined vehicle on a remote control display for displaying the remote control screen  212   b , which is a screen different from the monitor display for displaying the monitor screen  212   a.    
     Further, when the autonomous driving determination means  232  determines that a predetermined vehicle among a plurality of vehicles to be monitored is not able to perform autonomous driving, the control means  213 , as indicated by an arrow Y 3  in  FIG.  5   , may display video image data of the predetermined vehicle by setting a part of the display area of the display means  212  as the remote control screen  212   b  and setting a part of the display area of the display means  212  other than the former part as the monitor screen  212   a . At this time, the control means  213  makes the remote control screen  212   b  larger than the monitor screen  212   a . Further, the monitor screen  212   a  may display video image data of the plurality of vehicles side by side. 
     Further, when the autonomous driving determination means  232  determines that it is highly unlikely that a predetermined vehicle among a plurality of vehicles to be monitored will be able to perform autonomous driving, the control means  213 , as indicated by the arrow Y 3  in  FIG.  5   , may change display forms of the plurality of vehicles to be monitored on the monitor screen  212   a . For example, the control means  213  may display an enlarged or emphasized monitor screen  212   a   1  of the predetermined vehicle. That is, when it is determined that it is highly unlikely that a predetermined vehicle among a plurality of vehicles will able to perform autonomous driving, the control means  213  may display the video image data of the predetermined vehicle on the monitor screen  212   a  so that the size of the video image data of the predetermined vehicle becomes larger than that of the video image data of the vehicles other than the predetermined vehicle. 
     Note that although the present invention has been described as a hardware configuration in the above example embodiments, the present invention is not limited thereto. In the present invention, processing of each component can also be implemented by causing a Central Processing Unit (CPU) to execute a computer program. 
     Further, specifically, each apparatus of an image processing system may be implemented by using a combination of hardware and software. In a form of the combination of hardware and software, an image processing program is developed in a Random Access Memory (RAM), and hardware such as a control unit (Central Processing Unit (CPU)), is operated based on the program, whereby each unit is implemented as various type of means. Further, the program may be recorded on a recording medium and then distributed. The program recorded on the recording medium is loaded into the memory by wire, wirelessly, or via recording medium itself to operate the control unit and the like. Note that examples of the recording medium include an optical disk, a magnetic disk, a semiconductor memory apparatus, and a hard disk. 
     In the above example embodiments, the program can be stored and provided to a computer using any type of non-transitory computer readable media. Non-transitory computer readable media include any type of tangible storage media. Examples of non-transitory computer readable media include magnetic storage media (specifically, floppy disks, magnetic tapes, and hard disk drives), optical magnetic storage media (specifically, magneto-optical disks), CD-ROM (Read Only Memory), CD-R, CD-R/W, and semiconductor memories (specifically, mask ROM, PROM (Programmable ROM), EPROM (Erasable PROM), flash ROM, and RAM (Random Access Memory)). The program may be provided to a computer using any type of transitory computer readable media. Examples of transitory computer readable media include electric signals, optical signals, and electromagnetic waves. Transitory computer readable media can provide the program to a computer via a wired communication line (e.g., electric wires, and optical fibers) or a wireless communication line. 
     Although the present invention has been described with reference to the example embodiments, the present invention is not limited to the above-described example embodiments. Various changes that may be understood by those skilled in the art may be made to the configurations and details of the present invention within the scope of the invention.
