[Configuration of imaging device]
1A, 1 </ b> B, and 1 </ b> C illustrate a state in which the imaging apparatus 1 to which the imaging apparatus according to the present invention is applied holds the mobile terminal 2. 1A is a diagram of the imaging device 1 and the portable terminal 2 observed from the front (that is, the display side of the portable terminal 2), and FIG. 1B is an observation of the imaging device 1 and the portable terminal 2 from the back. FIG. FIG. 1C is a view of the imaging device 1 and the portable terminal 2 observed from the side. As will be described later, the imaging device 1 is installed on a dashboard or the like of a vehicle, functions as a normal drive recorder when the mobile terminal 2 is attached, and detects a malfunction in the vehicle when the mobile terminal 2 is not attached. Function as.

  As shown in FIGS. 1A to 1C, the imaging device 1 mainly includes an attachment portion 3, an arm 4, and a housing portion 5. The attachment portion 3 has a substantially disk shape, and is fixed in a state where the bottom surface is in surface contact with an installation surface such as a dashboard of a vehicle to which the imaging device 1 is attached. The arm 4 has one end connected to the attachment portion 3 and the other end connected to the housing portion 5.

  The casing 5 has a substantially cylindrical shape and is supported by the arm 4. As will be described later, the casing 5 is connected to the arm 4 in such a manner that it can rotate in a direction substantially parallel to the installation surface of the imaging device 1. A camera 6 for photographing is provided at one end of the housing 5, and a magnet 8 that generates a magnetic field is provided at the end of the housing 5 opposite to the end where the camera 6 is provided. The magnet unit 8 is fitted into the groove of the magnetic body 10 attached to the back surface of the mobile terminal 2. Here, the magnetic body 10 is a ferromagnetic body such as iron. Therefore, the magnet unit 8 supports the mobile terminal 2 to which the magnetic body 10 and the magnetic body 10 are attached by a magnetic force while being fitted in the magnetic body 10. The camera 6 is an example of the “imaging unit” in the present invention, and the magnet unit 8 is an example of the “support unit” in the present invention.

  The mobile terminal 2 is a display terminal having a display such as a smartphone, for example, and a magnetic body 10 is pasted on the back surface. Note that the surface of the magnetic body 10 to be attached to the mobile terminal 2 has, for example, adhesiveness or adsorptivity, and is attached to an arbitrary position on the back surface of the mobile terminal 2. In the example of FIG. 1, the mobile terminal 2 is fixed to the housing part 5 of the imaging device 1 by a magnetic force that the magnet part 8 attracts the magnetic body 10. The mobile terminal 2 is installed with a navigation application capable of executing processing linked to the imaging device 1. For example, the portable terminal 2 receives an image captured by the camera 6 of the imaging device 1 from the imaging device 1 based on the above-described application in a wearing state fixed to the housing unit 5 of the imaging device 1, and displays the image on the display. Display. In the example of FIG. 1A, the mobile terminal 2 displays an image of the front scenery of the vehicle taken by the camera 6 on the display.

  FIG. 2 is a functional block diagram of the imaging apparatus 1. As shown in FIG. 2, the imaging apparatus 1 includes a camera 6, a GPS receiver 11, a vibration sensor 12, a detachable sensor 13, an actuator 14, a short-range communication unit 15, a network communication unit 16, and a RAM 17. And a non-volatile memory 18.

  The GPS receiver 11 generates current position information indicating the current position by receiving radio waves carrying downlink data including positioning data from a plurality of GPS satellites. The vibration sensor 12 is an acceleration sensor, for example, and supplies a detection signal (also referred to as “vibration detection signal S <b> 1”) according to the magnitude of vibration to the control unit 19. The scale of the magnitude of vibration detected by the vibration sensor 12 may be any of displacement, speed, and acceleration. The vibration sensor 12 is an example of the “vibration detector” in the present invention.

  The attachment / detachment sensor 13 detects attachment / detachment of the mobile terminal 2 to / from the imaging device 1 and detects a detection signal (also referred to as “attachment / detachment detection signal S2”) indicating that the mobile terminal 2 is attached or detached. To supply. The detachable sensor 13 is formed, for example, in a groove of the magnetic body 10 in which the magnet portion 8 is fitted, and an electric power generated by a switch or the like that is pressed by the magnet portion 8 in a state where the magnet portion 8 is fitted in the magnetic body 10. It may be a signal.

  Based on the control of the control unit 19, the actuator 14 rotates the housing unit 5 horizontally by a predetermined angle with respect to the installation surface of the imaging device 1 when the portable terminal 2 is detached from the imaging device 1. FIGS. 3A and 3B show states before and after the rotation of the housing part 5 when the mobile terminal 2 is detached from the imaging device 1. As shown in FIGS. 3A and 3B, when the mobile terminal 2 is removed from the imaging device 1, the actuator 14 is configured to connect the housing portion 5 to the arm 4 based on the control of the control portion 19. Rotate about 180 degrees as an axis. As a result, the actuator 14 points the camera 6 in the direction in which the display of the mobile terminal 2 is directed in the mounted state of the mobile terminal 2 (that is, the direction in which the vehicle interior is the imaging range). 4A and 4B show states before and after the rotation of the housing 5 when the mobile terminal 2 is attached to the imaging device 1. As shown in FIGS. 4A and 4B, when the mobile terminal 2 is attached to the imaging device 1, the actuator 14 uses the control unit 19 to control the connection between the housing unit 5 and the arm 4. Rotate about 180 degrees as an axis. As a result, the actuator 14 points the camera 6 in the direction opposite to that shown in FIG. 4A (that is, the direction in which the front of the vehicle outside the passenger compartment is the shooting range). The actuator 14 is an example of the “rotation control unit” in the present invention.

  With reference to FIG. 2 again, each component of the imaging device 1 will be described. The near field communication unit 15 performs near field data communication with the portable terminal 2 attached to the imaging device 1 based on the control of the control unit 19. The communication by the short-range communication unit 15 is short-range wireless communication such as NFC (Near Field Communication) and Bluetooth (registered trademark). In the present embodiment, the short-range communication unit 15 transmits an image captured by the camera 6 to the mobile terminal 2 when the mobile terminal 2 is attached.

  The network communication unit 16 performs data communication via the network with the mobile terminal 2 removed from the imaging device 1 based on the control of the control unit 19. In the present embodiment, as will be described later, the network communication unit 16 is configured to notify the abnormality (“abnormality notification information” when the control unit 19 detects an abnormality while the mobile terminal 2 is disconnected from the imaging device 1. Is also transmitted to the portable terminal 2.

  The RAM 17 is a storage area that functions as an image buffer or the like that temporarily stores an image generated by the camera 6 based on the control of the control unit 19. The nonvolatile memory 18 is a storage medium such as a built-in flash memory or an SD card. For example, when the control unit 19 detects an abnormality such as dangerous driving, the control unit 19 writes an image for a predetermined time before the abnormality detection stored in the RAM 17 in the nonvolatile memory 18. Further, in the nonvolatile memory 18, information on the communication address of the mobile terminal 2 for communication between the mobile terminal 2 and the network communication unit 16, information on a threshold used for abnormality determination based on vibration described later, and setting of the camera 6 The information about is stored.

  The control unit 19 is a CPU or the like and controls the entire imaging apparatus 1. For example, the control unit 19 controls the actuator 14 when detecting attachment / detachment of the portable terminal 2 to / from the imaging device 1 based on the attachment / detachment detection signal S2 output from the attachment / detachment sensor 13. As a result, the control unit 19 controls the orientation of the camera 6 as described with reference to FIGS. The control unit 19 determines that an abnormality has occurred when the magnitude of vibration indicated by the vibration detection signal S1 supplied from the vibration sensor 12 exceeds a predetermined threshold (also referred to as “determination threshold”). Then, the image for a predetermined time before the abnormality detection stored in the RAM 17 is written in the nonvolatile memory 18 (that is, recording is performed). The control unit 19 is an example of a “control unit”, “first transmission unit”, “second transmission unit”, and a computer that executes a program in the present invention.

[Abnormality judgment processing]
Next, the abnormality determination process executed by the control unit 19 will be described. Schematically, the control part 19 makes the threshold value for determination used when the portable terminal 2 is a mounting | wearing state higher than the threshold value for determination used when the portable terminal 2 is a non-wearing state. As a result, the control unit 19 accurately detects the occurrence of an abnormality in each of the mounting state and the non-mounting state of the mobile terminal 2.

  FIG. 5A is a schematic diagram of the interior of the vehicle in a state where the mobile terminal 2 is mounted. In the example of FIG. 5A, the imaging device 1 is installed on the dashboard 29, and the driver attaches the mobile terminal 2 to the imaging device 1. In this case, the camera 6 is directed to the front window 25, and the display of the portable terminal 2 mounted on the opposite side to the camera 6 is directed to the driver in the vehicle interior. In the mounted state of the mobile terminal 2 shown in FIG. 5A, the control unit 19 transmits an image generated by the camera 6 to the mobile terminal 2 by the short-range communication unit 15. In this case, in the first example, the mobile terminal 2 displays the image received from the imaging device 1 on the display. At this time, the mobile terminal 2 may superimpose and display an image for assisting driving on the displayed image. In the second example, the mobile terminal 2 stores the image received from the imaging device 1 in a storage medium. As described above, the control unit 19 causes the mobile terminal 2 to appropriately display or store the image generated by the camera 6 by causing the short-range communication unit 15 to transmit the image generated by the camera 6 to the mobile terminal 2.

  Further, in the mounted state of the mobile terminal 2 shown in FIG. 5A, the imaging device 1 functions as a drive recorder. Specifically, the control unit 19 determines that an abnormality has occurred when the magnitude of vibration indicated by the vibration detection signal S <b> 1 supplied from the vibration sensor 12 exceeds the determination threshold, and is stored in the RAM 17. An image for a predetermined time before abnormality detection is written in the nonvolatile memory 18. At this time, the control unit 19 sets the determination threshold value to a threshold value (also referred to as “first threshold value”) for determining dangerous driving (including collision). The first threshold value is set based on experiments or the like in advance so as to be a value equal to or greater than the magnitude of vibration that can occur during normal driving that is not dangerous driving. Thus, in the wearing state of the portable terminal 2, the control unit 19 sets the determination threshold value to the first threshold value on the assumption that the vehicle is traveling. Thereby, the control part 19 suppresses suitably writing the image which the camera 6 produced | generated in the non-volatile memory 18 when the dangerous driving | operation does not generate | occur | produce.

  In addition, when the mobile terminal 2 is mounted, the control unit 19 preferably sets various settings of the camera 6 to settings suitable for photographing a scene outside the vehicle. For example, the control unit 19 sets the imaging sensitivity, F value, and / or focal length of the camera 6 to a value suitable for photographing a scene outside the vehicle. Thereby, the control part 19 can preserve | save the image which image | photographed the situation at the time of occurrence of dangerous driving clearly in the non-volatile memory 18 at the time of occurrence of dangerous driving. Note that the first threshold value and the setting information of the camera 6 that are used when the mobile terminal 2 is attached are stored in advance in, for example, the nonvolatile memory 18 or the like. In the wearing state of the mobile terminal 2 shown in FIG. 5A, the abnormality detection processing mode using the first threshold value is an example of the “second mode” in the present invention.

  FIG. 5B is a schematic view of the passenger compartment when the mobile terminal 2 is not attached. In the example of FIG. 5B, the driver removes the mobile terminal 2 from the imaging device 1 and leaves the vehicle. In this case, the control unit 19 detects that the portable terminal 2 has been removed based on the attachment / detachment detection signal S2, and rotates the housing unit 5 by about 180 degrees from the state of FIG. 6 is directed into the passenger compartment.

  When the portable terminal 2 is not attached as shown in FIG. 5B, the imaging device 1 functions as a security camera. Specifically, the control unit 19 determines that an abnormality has occurred when the magnitude of vibration indicated by the vibration detection signal S <b> 1 supplied from the vibration sensor 12 exceeds the determination threshold, and is stored in the RAM 17. An image for a predetermined time before abnormality detection is written in the nonvolatile memory 18. In this case, the control unit 19 generates abnormality notification information for notifying abnormality, and transmits the abnormality notification information generated by the network communication unit 16 to the mobile terminal 2. At this time, the control unit 19 may include a part or all of the image written in the nonvolatile memory 18 in the abnormality notification information and transmit it to the portable terminal 2.

  Here, in the non-wearing state of the mobile terminal 2 shown in FIG. 5B, the control unit 19 sets the determination threshold value to a predetermined threshold value (also referred to as “second threshold value”) that is smaller than the first threshold value. To do. The second threshold is, for example, a value larger than the magnitude of minute vibration that can occur when the vehicle is stopped, and smaller than the magnitude of vibration caused by contact of a person or an object with the vehicle. It is set based on. As described above, when the mobile terminal 2 is not attached, the control unit 19 sets the determination threshold value as the second threshold value based on the premise that the vehicle is stopped. As a result, the control unit 19 preferably detects an abnormality based on vibrations generated when a suspicious person such as a vandal touches the vehicle, writes an image in the non-volatile memory 18, or carries it by using the abnormality notification information. It is possible to notify the user of the terminal 2 of the abnormality.

  In addition, when the mobile terminal 2 is not attached, the control unit 19 preferably sets various settings of the camera 6 to settings suitable for photographing the vehicle interior. For example, the control unit 19 sets the imaging sensitivity, F value, and / or focal length of the camera 6 to values suitable for photographing the vehicle interior. Thereby, the control part 19 can produce | generate suitably the image which image | photographed clearly the mode of the vehicle interior when abnormality was detected. Note that the second threshold value and the setting information of the camera 6 that are used when the portable terminal 2 is not attached are stored in advance in, for example, the nonvolatile memory 18 or the like. In the non-wearing state of the mobile terminal 2 shown in FIG. 5B, the abnormality detection processing mode using the second threshold value is an example of the “first mode” in the present invention.

  FIG. 6 is an example of a flowchart executed by the control unit 19. The control unit 19 repeatedly executes the flowchart of FIG.

  First, the control part 19 determines whether the portable terminal 2 was attached or detached (step S101). For example, the control unit 19 determines whether or not the mobile terminal 2 is attached / detached based on the attachment / detachment detection signal S <b> 2 transmitted from the vibration sensor 12.

  And the control part 19 rotates the housing | casing part 5 by the actuator 14, when it is judged that the portable terminal 2 was attached or detached (step S101; Yes) (step S102). Specifically, when the mobile terminal 2 is detached from the imaging device 1, the control unit 19 attaches the housing unit 5 so that the camera 6 is directed into the vehicle interior, as shown in FIG. Rotate relative to part 3 and arm 4. On the other hand, when the mobile terminal 2 is attached to the imaging device 1, the control unit 19 is configured so that the camera 6 is directed outside the vehicle compartment (that is, the front window) as shown in FIG. Is rotated with respect to the mounting portion 3 and the arm 4.

  Next, the control unit 19 determines whether or not the mobile terminal 2 is in a wearing state (step S103). And the control part 19 sets the threshold value for determination to the 1st threshold value larger than a 2nd threshold value, and the various settings of the camera 6 for the imaging | photography outside a vehicle, when the portable terminal 2 is a mounting state (step S103; Yes). (Step S104). Thereby, the control unit 19 can accurately detect only the abnormality based on the dangerous driving, and can appropriately generate and store the image in which the scenery outside the vehicle is clearly captured when the abnormality is detected in the nonvolatile memory 18.

  On the other hand, when the mobile terminal 2 is not attached (step S103; No), the control unit 19 sets the determination threshold to a second threshold smaller than the first threshold and sets various settings of the camera 6 to in-vehicle shooting. (Step S105). Thereby, the control part 19 can detect correctly the abnormality of the vehicle at the time of parking of a vehicle, and can produce | generate suitably the image which image | photographed the state of the vehicle interior clearly at the time of abnormality.

  Thereafter, the control unit 19 performs abnormality determination based on the determination threshold set in step S104 or step S105 and the vibration detection signal S1 output from the vibration sensor 12 (step S106). Then, when the magnitude of vibration indicated by the vibration detection signal S <b> 1 exceeds the determination threshold, the control unit 19 writes the image in the RAM 17 in the nonvolatile memory 18. In addition, the control unit 19 transmits abnormality notification information to the mobile terminal 2 through the network communication unit 16 when the mobile terminal 2 is not attached.

  As described above, the imaging apparatus 1 according to the present embodiment includes the attachment unit 3 that can be attached to the vehicle, the camera (imaging unit) 6, the vibration sensor 12, and the control unit 19. The camera 6 is configured to be rotatable with respect to the attachment portion 3. The control unit 19 performs an abnormality determination using the second threshold value in a state where the mobile terminal 2 is not worn and an abnormality using a first threshold value higher than the second threshold value when the mobile terminal 2 is worn. The mode for performing the determination is switched according to the rotation of the camera 6 by the actuator 14. Thereby, the imaging device 1 functions as a holder and a drive recorder of the mobile terminal 2 when the mobile terminal 2 is mounted, and can suitably function as a security camera in the vehicle interior when the mobile terminal 2 is not mounted.

[Modification]
Hereinafter, modified examples suitable for the above-described embodiments will be described. The following modifications may be applied in any combination to the above-described embodiments.

(Modification 1)
The imaging device 1 may include a configuration in which the housing unit 5 is rotatable based on a manual operation instead of including a configuration in which the housing unit 5 automatically rotates in accordance with the attachment / detachment of the mobile terminal 2.

  In this case, for example, the arm 4 and the housing part 5 are connected by a ball link or the like, and the housing part 5 is rotatable with respect to the arm 4 at least along the installation surface. Then, when the user of the portable terminal 2 attaches the portable terminal 2 to the imaging device 1, the display of the portable terminal 2 is directed into the vehicle interior and the portable terminal 2 is detached from the imaging device 1 as shown in FIG. 4B, the housing 5 is manually operated so that the camera 6 faces the vehicle interior as shown in FIG. Also according to this aspect, the imaging device 1 preferably functions as a drive recorder when the vehicle is traveling, and functions as a security camera when the vehicle is parked.

  In addition, the imaging device 1 may be configured such that the housing unit 5 automatically rotates so that the camera 6 faces the vehicle interior only when the portable terminal 2 is detached. In this case, when the mobile terminal 2 is attached to the imaging apparatus 1, the mobile terminal 2 rotates the direction of the housing part 180 by 180 degrees before or after the mobile terminal 2 is attached.

  In the first modification, the control unit 19 sets the determination threshold to the first threshold or the second threshold based on whether or not the mobile terminal 2 is attached to the imaging device 1 and based on the angle of the housing unit 5. It may be determined whether or not to set. In this case, for example, the imaging device 1 is provided with an angle sensor for detecting the angle of the housing unit 5, and the control unit 19 determines the orientation of the camera 6 based on the output of the angle sensor. When the control unit 19 determines that the mobile terminal 2 is in the mounted state and the camera 6 is pointed out of the passenger compartment, the control unit 19 executes step S104 in FIG. 6 and the mobile terminal 2 is in the non-mounted state. If it is determined that the camera 6 is directed toward the passenger compartment, step S105 is executed. Thereby, even when the control unit 19 adjusts the rotation angle of the housing unit 5 by manual operation, the control unit 19 suitably determines whether the camera 6 is photographing outside the vehicle compartment or inside the vehicle interior, and a threshold value for determination or the like. Can be set accurately.

(Modification 2)
In the configuration of FIG. 1 and the like, the orientation of the camera 6 and the orientation of the display of the mobile terminal 2 attached to the imaging device 1 differed by about 180 degrees in the mounted state of the mobile terminal 2, but the present invention is applicable. However, the configuration is not limited to this. For example, when the display of the portable terminal 2 attached to the imaging device 1 is pointed at the driver's seat, each of the camera 6 and the magnet unit 8 is arranged so that the camera 6 is suitable for photographing the front of the vehicle. An installation angle may be set.

(Modification 3)
In the configuration of FIG. 1 and the like, the casing 5 is configured to be rotatable with respect to the arm 4, but instead, the arm 4 may be configured to be rotatable with respect to the attachment unit 3. In this case, the arm 4 and the housing part 5 rotate with respect to the attachment part 3 substantially parallel to the installation surface.
