[0019] [Embodiment] A video recording device and a video recording device control program according to an embodiment will be described with reference to FIGS.

[0020] First, the hardware configuration of a video recording device according to an embodiment will be described with reference to Fig. 1 to Fig. 3. Fig. 1 and Fig. 2 are diagrams showing an example of the external appearance of a video recording device according to an embodiment. Fig. 3 is a diagram showing an example of the hardware configuration of a video recording device according to an embodiment.

[0021] The video recording device 1 shown in Figures 1, 2, and 3 is a device that records the inside and outside of a vehicle when a traffic accident occurs as video for the purpose of resolving the traffic accident appropriately. The video recording device 1 is a device called a drive recorder in Japan and a dashcam in Europe and the United States. Note that the video recording device 1 is not limited to a drive recorder (dashcam), and may be a general-purpose terminal device equipped with a camera, such as a smartphone or tablet.

[0022] As shown in Fig. 1, Fig. 2 and Fig. 3, the video recording device 1 includes a housing 101, a fitting member 102, an attachment / detachment button 103, a CPU (Central Processing Unit) 104, a front camera 105, an in-camera 106, a recording unit 107, a touch panel display 108, an emergency call button 109, a GPS (Global Positioning System) receiver 110, a sensor 111, a communication unit 112, a connector connection unit 113 and a battery 114. Fig. 1 is a diagram showing the side of the video recording device 1 on which the front camera 105 is attached. Meanwhile, Fig. 2 is a diagram showing the side of the video recording device 1 on which the in-camera 106 is attached.

[0023] Housing 101 has, on its surface, a fitting member 102, an attachment / detachment button 103, a front camera 105, an in-camera 106, a touch panel display 108, an emergency call button 109, and a connector connection section 113. Housing 101 also houses CPU 104, a recording section 107, a GPS receiver 110, a sensor 111, a communication section 112, and a battery 114.

[0024] 1 and 2, the fitting member 102 is attached to, for example, the upper surface of the housing 101, and has a protrusion 102C formed thereon. The protrusion 102C is fitted into, for example, a recess 200C formed in a support member 200 attached to the windshield F of the vehicle.

[0025] Furthermore, the fitting member 102 may have a rod-shaped fixing member that protrudes from the convex portion 102C and enters a hole formed in the concave portion 200C to maintain the state in which the convex portion 102C and the concave portion 200C are fitted together. Alternatively, the support member 200 may have a rod-shaped fixing member that protrudes from the concave portion 200C and enters a hole formed in the convex portion 102C to maintain the state in which the convex portion 102C and the concave portion 200C are fitted together.

[0026] The protruding portion 102C and the recessed portion 200C may each have a metal terminal attached thereto. At least one of these two terminals transmits a signal indicating that the protruding portion 102C and the recessed portion 200C are engaged with each other to the CPU 104 when the protruding portion 102C and the recessed portion 200C are engaged with each other. As a result, the two terminals cause the CPU 104 to recognize that the protruding portion 102C and the recessed portion 200C are engaged with each other. On the other hand, at least one of these two terminals transmits a signal indicating that the protruding portion 102C and the recessed portion 200C are separated from each other to the CPU 104 when the protruding portion 102C and the recessed portion 200C are separated from each other. As a result, the two terminals cause the CPU 104 to recognize that the protruding portion 102C and the recessed portion 200C are separated from each other.

[0027] The video recording device 1 records the interior and exterior conditions of the vehicle as images when attached to the vehicle by fitting the convex portion 102C into the concave portion 200C. On the other hand, the video recording device 1 records the interior and exterior conditions of the vehicle as images when detached from the vehicle by separating the convex portion 102C from the concave portion 200C.

[0028] The attachment / detachment button 103 is a button that is mechanically linked to the fixing member described above, and is a button that is pressed to switch between a state in which the fixing member has entered the hole and a state in which the fixing member has not entered the hole.

[0029] The CPU 104 reads and executes the video recording device control program to realize the functions shown in Fig. 4. The CPU 104 may also read and execute programs other than the video recording device control program to realize functions necessary for realizing each function of the video recording device 1.

[0030] The front camera 105 is a camera that captures at least one of moving images and still images of the inside and outside of the vehicle. When the video recording device 1 is attached to the vehicle, the front camera 105 captures at least one of moving images and still images of the front of the vehicle mainly through the windshield of the vehicle. On the other hand, when the video recording device 1 is detached from the vehicle, the front camera 105 captures at least one of moving images and still images of the inside and outside of the vehicle, not limited to the situation in front of the vehicle.

[0031] The in-camera 106 is a camera that captures at least one of moving images and still images of the inside and outside of the vehicle. When the video recording device 1 is attached to the vehicle, the in-camera 106 mainly captures at least one of moving images and still images of the inside of the vehicle cabin. When the video recording device 1 is attached to the vehicle, the in-camera 106 may capture at least one of moving images and still images of at least one of the sides and rear of the vehicle through the vehicle window. On the other hand, when the video recording device 1 is detached from the vehicle, the in-camera 106 captures at least one of moving images and still images of the inside and outside of the vehicle, not limited to the inside, sides and rear of the vehicle.

[0032] The recording unit 107 has at least one storage medium. The recording unit 107 includes, for example, a main storage device and an auxiliary storage device.

[0033] The main storage device is, for example, a RAM (Random Access Memory), and stores in advance the video recording device control program that is read and executed by the CPU 104 and other video recording device control programs.

[0034] The auxiliary storage device is, for example, a hard disk drive (HDD: Hard Disk Drive), a solid state drive (SSD: Solid State Drive), a flash memory, or a read only memory (ROM). The auxiliary storage device stores, for example, moving images and still images captured by the front camera 105 and moving images and still images captured by the in-camera 106.

[0035] Touch panel display 108 is a type of interface used to operate video recording device 1. For example, touch panel display 108 displays a graphical user interface (GUI) used to operate video recording device 1. Touch panel display 108 may also display moving images and still images captured by front camera 105 and moving images and still images captured by in-camera 106 as necessary.

[0036] The emergency call button 109 is a type of interface used to operate the video recording device 1. The emergency call button 109 is a button that is pressed to notify a customer service desk of a road service provider, an insurance company, a security company, the police, an ambulance, a fire department, etc., in the event of a traffic accident, injury, illness, or other trouble.

[0037] The GPS receiver 110 receives signals required to calculate the position of the video recording device 1 from artificial satellites.

[0038] The sensor 111 includes, for example, at least one of an illuminance sensor, an acceleration sensor, a geomagnetic sensor, and an air pressure sensor. The illuminance sensor detects the illuminance around the video recording device 1. The acceleration sensor detects the acceleration of the video recording device 1. The geomagnetic sensor detects the magnitude and direction of the magnetic field around the video recording device 1. The air pressure sensor detects the air pressure around the video recording device 1.

[0039] The communication unit 112 communicates with other devices through a network. The network may be, for example, the Internet, a wide area network (WAN), or a local area network (intranet). For example, the video recording device 1 may communicate with a vehicle using the communication unit 112 to obtain, for example, data indicating the vehicle speed measured by a vehicle speed sensor mounted on the vehicle, data indicating the set gear stage of the vehicle, and the like.

[0040] The connector connection unit 113 is an input / output port to which a cable is connected to connect the video recording device 1 to another device. For example, the video recording device 1 may obtain, through the connector connection unit 113, data indicating the vehicle speed measured by a vehicle speed sensor mounted on the vehicle, data indicating the set gear stage of the vehicle, and the like.

[0041] The battery 114 supplies power to each element constituting the video recording device 1 .

[0042] 4 is a diagram showing an example of the software configuration of the video recording device according to the embodiment. The video recording device 1, for example, reads and executes a video recording device control program using the CPU 104 to realize the data acquisition unit 121, the determination unit 122, and the control unit 123 shown in FIG.

[0043] The data acquisition unit 121 acquires data indicating the result of detecting a phenomenon related to the operation of removing the video recording device 1 from the vehicle. The data is, for example, data indicating a moving image or a still image captured by the front camera 105 or the in-camera 106. Alternatively, the data is data indicating the illuminance detected by an illuminance sensor. Alternatively, the data is data indicating the acceleration detected by an acceleration sensor.

[0044] The data acquisition unit 121 may also acquire data indicating the result of detecting a phenomenon that occurs before the start of an operation to remove the video recording device 1 from the vehicle. Examples of such data include data indicating a moving image or a still image captured before the user touches the video recording device 1 to remove it, data indicating the illuminance detected by an illuminance sensor before the operation is performed, and data indicating the acceleration detected by an acceleration sensor before the operation is performed.

[0045] The data acquisition unit 121 may also acquire data indicating the result of detecting a phenomenon that occurs after the start of an action to remove the video recording device 1 from the vehicle. Examples of such data include data indicating a moving image or a still image captured after the user touches the video recording device 1 to remove it, data indicating the illuminance detected by an illuminance sensor after the action is performed, and data indicating the acceleration detected by an acceleration sensor after the action is performed.

[0046] Furthermore, the data acquisition unit 121 may acquire one of the above-mentioned data as the first data, and acquire data different from the data as the second data. The first data and the second data may be handled differently by the determination unit 122 as necessary. In this case, both the first data and the second data may indicate a result of detecting a first phenomenon related to the operation of removing the video recording device 1 from the vehicle. Alternatively, in this case, the first data may indicate a result of detecting a first phenomenon related to the operation of removing the video recording device 1 from the vehicle, and the second data may indicate a result of detecting a second phenomenon related to the operation of removing the video recording device 1 from the vehicle and different from the first phenomenon.

[0047] The determination unit 122 determines whether or not the result indicated by the data acquired by the data acquisition unit 121 satisfies a predetermined condition.

[0048] The predetermined condition is, for example, that when the data is data showing a moving image or a still image captured by the front camera 105 or the in-camera 106, the moving image or the still image shows the user's action of removing the video recording device 1. Alternatively, the predetermined condition is, for example, that when the data is data showing a moving image or a still image captured by the front camera 105 or the in-camera 106, the moving image or the still image shows the user's action of removing the video recording device 1.

[0049] For example, when either of these two actions is performed, the user's palm is captured by at least one of the front camera 105 and the in-camera 106. Therefore, examples of the moving images and still images that satisfy the above-mentioned predetermined conditions include moving images and still images in which the user's palm is captured. In addition, the determination of whether the user's palm is captured in a moving image or a still image is performed using, for example, a trained machine learning model.

[0050] On the other hand, for example, when the user is about to operate touch panel display 108 or when the user has operated touch panel display 108, the user's finger is captured at a certain size or larger by in-camera 106. Therefore, examples of videos and still images that do not satisfy the above-mentioned predetermined condition include videos and still images in which the user's finger is captured at a certain size or larger. In addition, the determination of whether the user's finger is captured at a certain size or larger in a video or still image is performed using, for example, a trained machine learning model.

[0051] Furthermore, the predetermined condition is, for example, that when the data is data showing a moving image or a still image captured by the front camera 105 or the in-camera 106, the change in the moving image or still image within a certain period of time is equal to or greater than a certain amount. The change in the moving image or still image within a certain period of time referred to here is, for example, a change in the position of the contour of an object shown in the moving image or still image in the moving image or still image. Examples of the object include the face and arms of the user in the vehicle cabin, and a seat present in the vehicle cabin. The process of recognizing the object is performed, for example, using a trained machine learning model.

[0052] In addition, the specified condition is, for example, when the data represents a moving image or a still image captured by the front camera 105 or the in-camera 106, the entire moving image or still image becomes darker than a certain level when the front camera 105 or the in-camera 106 is covered by the user's hand.

[0053] Alternatively, the specified condition is that, when the data indicates the illuminance detected by an illuminance sensor, the illuminance indicated by the data is less than a specified threshold due to the front camera 105 or the in-camera 106 being covered by the user's hand.

[0054] Alternatively, the predetermined condition is that, when the data indicates acceleration detected by an acceleration sensor, the absolute value of the acceleration indicated by the data exceeds a predetermined threshold value as a result of the user moving the video recording device 1. Alternatively, the predetermined condition is that, when the data indicates acceleration detected by an acceleration sensor, the acceleration in a predetermined direction indicated by the data exceeds a predetermined threshold value as a result of the user moving the video recording device 1.

[0055] In addition, when the above-mentioned first data and second data are acquired by the data acquisition unit 121, the judgment unit 122 may judge whether the result indicated by the first data and the result indicated by the second data satisfy a predetermined condition.

[0056] For example, the determination unit 122 may determine whether the result indicated by the first data satisfies a first condition that is a part of the predetermined condition, and may determine whether the result indicated by the second data satisfies a second condition that is a part of the predetermined condition. At this time, the determination unit 122 may determine that the predetermined condition is satisfied when both the first condition and the second condition are satisfied. Alternatively, at this time, the determination unit 122 may determine that the predetermined condition is satisfied when it is determined that the result indicated by the first data does not satisfy the first condition but that the result indicated by the second data satisfies the second condition.

[0057] If the control unit 123 determines that the result indicated by the data acquired by the data acquisition unit 121 satisfies a specified condition, it controls the video recording device 1 to disable operations on the interface used to operate the video recording device 1.

[0058] Furthermore, when it is determined that the result indicated by the first data and the result indicated by the second data satisfy a predetermined condition, the control unit 123 controls the video recording device 1 to disable operations on the interface.

[0059] In addition, when the control unit 123 determines that the result indicated by the first data satisfies the first condition and that the result indicated by the second data satisfies the second condition, it controls the video recording device 1 to disable operations on the interface.

[0060] In addition, the control unit 123 controls the video recording device 1 to disable operations on the interface when it is determined that the result indicated by the first data does not satisfy the first condition, but the result indicated by the second data satisfies the second condition.

[0061] If it is determined that the result indicated by the data satisfies a predetermined condition, the control unit 123 may further control the video recording device 1 not to communicate with other devices.

[0062] Furthermore, the control unit 123 may further control the video recording device 1 not to delete at least one of the captured moving images and still images when it is determined that the result indicated by the data satisfies a specified condition.

[0063] Next, an example of the process executed by the video recording device 1 according to the embodiment will be described with reference to Fig. 5. Fig. 5 is a flowchart showing an example of the process executed by the video recording device according to the embodiment. For example, the video recording device 1 executes the process shown in Fig. 5 every time at least one of the above-mentioned data is acquired. Alternatively, the video recording device 1 executes the process shown in Fig. 5 every time a set of the above-mentioned first data and second data is acquired.

[0064] In step S10, the data acquisition unit 121 acquires from the sensor 111 data indicating the result of detecting a phenomenon related to the operation of removing the video recording device 1 from the vehicle.

[0065] In step S20, the determination unit 122 determines whether the result indicated by the data acquired in step S10 satisfies a predetermined condition. If the determination unit 122 determines that the result indicated by the data acquired in step S10 satisfies the predetermined condition (step S20: YES), the process proceeds to step S30. On the other hand, if the determination unit 122 determines that the result indicated by the data acquired in step S10 does not satisfy the predetermined condition (step S20: NO), the process ends.

[0066] In step S30, the control unit 123 controls the video recording device 1 so as to disable operations on the interface used to operate the video recording device 1.

[0067] The video recording device and the video recording device control program according to the embodiment have been described above.

[0068] The video recording device 1 includes a data acquisition unit 121, a determination unit 122, and a control unit 123. The data acquisition unit 121 acquires data indicating the result of detecting a phenomenon related to the action of removing the video recording device 1 from the vehicle. The determination unit 122 determines whether or not the result indicated by the data satisfies a predetermined condition. When it is determined that the result indicated by the data satisfies the predetermined condition, the control unit 123 controls the video recording device 1 to disable operations on an interface used to operate the video recording device 1.

[0069] This allows the video recording device 1 to detect when the video recording device 1 is removed from the vehicle, and reduces the occurrence of a situation in which the interface is mistakenly operated and unnecessary processing is executed when the video recording device 1 is removed from the vehicle.

[0070] Furthermore, the video recording device 1 acquires first data and second data indicating the result of detecting a phenomenon related to the action of removing the video recording device 1 from the vehicle. Then, when it is determined that the result indicated by the first data and the result indicated by the second data satisfy a predetermined condition, the video recording device 1 controls the video recording device 1 to disable operations on the interface. In other words, the video recording device 1 uses multiple pieces of data to determine whether the video recording device 1 will be removed from the vehicle from multiple perspectives.

[0071] This enables the video recording device 1 to more accurately detect the action of removing the video recording device 1 from the vehicle, and to control the video recording device 1 to disable operations on the interface when truly necessary.

[0072] In addition, when it is determined that the result indicated by the first data satisfies a first condition and the result indicated by the second data satisfies a second condition, the video recording device 1 controls the video recording device 1 to disable operations on the interface.

[0073] This enables the video recording device 1 to more accurately detect the action of removing the video recording device 1 from the vehicle, and to control the video recording device 1 to disable operations on the interface when truly necessary.

[0074] In addition, when it is determined that the result indicated by the first data does not satisfy the first condition, but the result indicated by the second data satisfies the second condition, the video recording device 1 controls the video recording device 1 to disable operations on the interface.

[0075] As a result, even if the video recording device 1 cannot accurately detect the action of removing the video recording device 1 from the vehicle based on the first condition, the video recording device 1 can detect the action based on the second condition and control the video recording device 1 to disable operations on the interface.

[0076] Furthermore, the video recording device 1 obtains data indicating the result of detecting a phenomenon that occurs before the operation of removing the video recording device 1 from the vehicle is started. This allows the video recording device 1 to detect the operation of removing the video recording device 1 from the vehicle before the operation is started, and to control the video recording device 1 to disable operations on the interface before the video recording device 1 is erroneously operated due to the operation.

[0077] Furthermore, the video recording device 1 obtains data indicating the results of detecting a phenomenon that occurs after the operation of removing the video recording device 1 from the vehicle is started.

[0078] This allows the video recording device 1 to detect that the action of removing the video recording device 1 from the vehicle is definitely being performed, and can control the video recording device 1 to disable operations on the interface before the video recording device 1 is mistakenly operated by the action.

[0079] Furthermore, when it is determined that the result indicated by the data satisfies a predetermined condition, the video recording device 1 further controls the video recording device 1 so as not to execute communication with other devices.

[0080] This allows the video recording device 1 to reduce the occurrence of a situation in which communication is erroneously performed due to the action of removing the video recording device 1 from the vehicle.

[0081] In addition, if it is determined that the result indicated by the data satisfies a specified condition, the video recording device 1 further controls the video recording device 1 so as not to delete at least one of the captured moving images and still images.

[0082] This makes it possible for the video recording device 1 to reduce the occurrence of a situation in which at least one of moving images and still images is mistakenly deleted when the video recording device 1 is removed from the vehicle.

[0083] In the above embodiment, the touch panel display 108 and the emergency call button 109 are given as examples of the interface of the video recording device 1, but the interface is not limited to these. The interface includes at least some of the buttons, switches, etc. used to operate the video recording device 1.

[0084] In addition, in the above-described embodiment, an example was given in which the functions of the video recording device 1 shown in FIG. 4 are realized by the CPU 104 that reads and executes a video recording device control program, but this is not limited to the above.

[0085] At least some of the functions of the video recording device 1 shown in Fig. 4 may be realized by hardware including circuitry such as a large scale integration (LSI), an application specific integrated circuit (ASIC), a field programmable gate array (FPGA), a graphics processing unit (GPU), etc. Alternatively, at least some of the functions of the video recording device 1 shown in Fig. 4 may be realized by a combination of software and hardware.

[0086] Although an embodiment of the present invention has been described in detail above with reference to the drawings, the specific configuration is not limited to this embodiment, and at least one of various combinations, modifications, substitutions, and design changes may be made within the scope not departing from the gist of the present invention.

[0087] The effects of the above-described embodiments of the present invention are shown as examples.
