[0012] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of a recording device for a vehicle and a recording control method according to the present invention will be described in detail below with reference to the accompanying drawings. It should be noted that the present invention is not limited to the following embodiment.

[0013] [First embodiment] <Vehicle Recording Device> FIG. 1 is a schematic diagram for explaining a first arrangement of the vehicle recording device 10 according to the first embodiment. FIG. 2 is a schematic diagram for explaining a second arrangement of the vehicle recording device 10 according to the first embodiment. FIG. 3 is a block diagram showing an example of the configuration of the vehicle recording device 10 according to the first embodiment. The vehicle recording device 10 has a first housing 11 and a second housing 12 that supports the first housing 11. The second housing 12 is fixed to the front of the vehicle interior. The second housing 12 is arranged, for example, on the dashboard.

[0014] The first housing 11 is movable relative to the second housing 12 fixed to the vehicle. In this embodiment, the first housing 11 is movable relative to the second housing 12 about a rotation axis AX. The second housing 12 supports the first housing 11 in a first arrangement and a second arrangement. The first housing 11 can be in a first arrangement in which it is open relative to the second housing 12 as shown in FIG. 1, and in a second arrangement in which it is closed relative to the second housing 12 as shown in FIG. 2. The first housing 11 is in the first arrangement while the vehicle is traveling, and in the second arrangement when the vehicle is parked. The first housing 11 is supported by the second housing 12 in the first arrangement and the second arrangement. The first housing 11 in the first arrangement stands upright relative to the second housing 12. The first housing 11 in the second arrangement is arranged so as to overlap the second housing 12.

[0015] The first housing 11 includes a camera 210 disposed on the surface 11a and a display unit 250 disposed on the opposite side to the surface 11a. When the first housing 11 is in the first arrangement state, the camera 210 is disposed facing the windshield facing the front of the vehicle, and the display unit 250 is disposed facing the driver of the vehicle. When the first housing 11 is in the second arrangement state, the camera 210 faces upward or downward, and the display unit 250 is disposed overlapping the surface 12a of the second housing 12. In this embodiment, since the second housing 12 is disposed on the dashboard of the vehicle, when the first housing 11 is in the second arrangement state, the camera 210 is disposed facing upward. For example, when the second housing 12 is disposed on the ceiling of the vehicle interior, when the first housing 11 is in the second arrangement state, the camera 210 is disposed facing downward.

[0016] The vehicular recording device 10 may be a device installed in the vehicle, or may be a portable device that can be used in the vehicle. The vehicular recording device 10 may be realized by including the functions or configurations of a device or a navigation device that is pre-installed in the vehicle.

[0017] The vehicle recording device 10 has a housing sensor 200, a camera (photographing unit) 210, a recording unit 220, an operation unit 240, a display unit 250, an acceleration sensor 260, a GNSS (Global Navigation Satellite System) receiving unit 270, a drive unit 280, and a vehicle recording control device 100.

[0018] The housing sensor 200 is a sensor that detects the state of the housing of the vehicle recording device 10. More specifically, the housing sensor 200 detects the state of the first housing 11 relative to the second housing 12. The housing sensor 200 detects whether the first housing 11 is in an open state or a closed state relative to the second housing 12. For example, the housing sensor 200 may detect the rotation of the first housing 11 about the central axis AX. For example, the housing sensor 200 may detect whether the first housing 11 is in contact with the surface 12a of the second housing 12. The housing sensor 200 outputs the detection result as housing information to the housing information acquisition unit 110 of the vehicle recording control device 100.

[0019] The camera 210 captures an image in the direction in which the camera 210 is pointed. In this embodiment, the camera 210 is a camera capable of capturing an image of a half 180° sky. The camera 210 is disposed on the surface 11a of the first housing 11. The camera 210 captures an image at all times from when the engine starts to when it stops, and when the vehicle is parked. The camera 210 captures an image at all times, whether the first housing 11 is in the first arrangement state or the second arrangement state. The camera 210 outputs the captured image data to the image data acquisition unit 120 of the vehicle recording control device 100. The image data is, for example, a moving image composed of images of 30 frames per second.

[0020] The recording unit 220 is used for temporary storage of data in the vehicle recording device 10. The recording unit 220 is, for example, a semiconductor memory element such as a RAM (Random Access Memory) or a flash memory, or a recording unit such as a memory card. Alternatively, the recording unit 220 may be an external recording unit wirelessly connected via a communication device (not shown). The recording unit 220 records the loop recorded video data or the event recorded data based on a control signal output from the recording control unit 124 of the vehicle recording control device 100.

[0021] The operation unit 240 can accept various operations on the vehicular recording device 10. For example, the operation unit 240 can accept an operation to manually save the captured video data in the recording unit 220 as event recording data. For example, the operation unit 240 can accept an operation to play back the loop recorded video data or event recording data recorded in the recording unit 220. For example, the operation unit 240 can accept an operation to erase the event recording data recorded in the recording unit 220. For example, the operation unit 240 can accept an operation to end the loop recording. The operation unit 240 outputs operation information to the operation control unit 130 of the vehicular recording control device 100.

[0022] The display unit 250 is a display device provided in the vehicle recording device 10. The display unit 250 is a display including, for example, a liquid crystal display (LCD) or an organic electro-luminescence (EL) display. The display unit 250 displays video based on a video signal output from the display control unit 131 of the vehicle recording control device 100. The display unit 250 displays video captured by the camera 210 or video recorded in the recording unit 220.

[0023] Display unit 250 is disposed in first housing 11. When first housing 11 is in the first arrangement state, the display surface of display unit 250 faces the interior of the vehicle, which is an orientation that is visible to the driver and passengers of the vehicle. When first housing 11 is in the second arrangement state, display unit 250 overlaps second housing 12 and the display surface is not exposed to the outside. Display unit 250 displays an image when first housing 11 is in the first arrangement state, and does not have to display an image when first housing 11 is in the second arrangement state.

[0024] The acceleration sensor 260 is a sensor that detects acceleration applied to the vehicle. The acceleration sensor 260 outputs the detection result to the acceleration information acquisition unit 132 of the vehicle recording control device 100. The acceleration sensor 260 is a sensor that detects acceleration in, for example, three axial directions. The three axial directions are the front-rear direction, the left-right direction, and the up-down direction of the vehicle.

[0025] The GNSS receiver 270 receives GNSS signals from GNSS satellites (not shown) and outputs the received radio wave signals to the position information acquirer 134 of the vehicle recording control device 100.

[0026] The driving unit 280 is a driving mechanism that changes the arrangement of the first housing 11. In this embodiment, the driving unit 280 changes the first housing 11 between a first arrangement state and a second arrangement state. The driving unit 280 changes the first housing 11 around the central axis AX.

[0027] <Recording control device for vehicles> The vehicle record control device 100 is an arithmetic processing device (control device) configured with, for example, a CPU (Central Processing Unit). The vehicle record control device 100 includes an internal memory (not shown), which is used for temporary storage of data in the vehicle record control device 100. The vehicle record control device 100 loads a stored program into the internal memory and executes instructions included in the program. The vehicle record control device 100 includes a case information acquisition unit 110, a state determination unit 111, a video data acquisition unit 120, a buffer memory 121, a video data processing unit 122, a cutout processing unit 123, a recording control unit 124, a playback control unit 125, an operation control unit 130, a display control unit 131, an acceleration information acquisition unit 132, an event detection unit 133, a position information acquisition unit 134, a vehicle state determination unit 135, and a drive control unit 136, which are connected to a bus 100X.

[0028] The case information acquisition unit 110 acquires case information from the case sensor 200 .

[0029] The state determination unit 111 determines the state of the vehicular recording device 10 based on the case information acquired by the case information acquisition unit 110. The state determination unit 111 determines whether the first case 11 is in an open state or a closed state relative to the second case 12 based on the case information. The state determination unit 111 determines whether the first case 11 is in a first arrangement state or a second arrangement state based on the case information.

[0030] Video data acquisition unit 120 acquires video data captured by camera 210. More specifically, video data acquisition unit 120 acquires video data output by camera 210, and outputs it to buffer memory 121. Video data acquisition unit 120 controls the shooting operation of camera 210.

[0031] Buffer memory 121 is a memory that temporarily stores video data, and temporarily records, while updating, a certain period of video data acquired by video data acquisition unit 120, or video data acquired by video data acquisition unit 120 and a specified range cut out by cut-out processing unit 123.

[0032] The video data processing unit 122 converts the video data temporarily stored in the buffer memory 121 into an arbitrary file format, such as MP4 format, encoded with an arbitrary codec, such as H.264 or MPEG-4 (Moving Picture Experts Group). The video data processing unit 122 generates video data as a file for a certain period of time from the video data temporarily stored in the buffer memory 121. As a specific example, the video data processing unit 122 generates 60 seconds of video data as a file in the order of recording from the video data temporarily stored in the buffer memory 121. The video data processing unit 122 outputs the generated video data to the recording control unit 124. The video data processing unit 122 also outputs the generated video data to the display control unit 131. The period of the video data generated as a file is set to 60 seconds as an example, but is not limited to this. The video data referred to here may be data including audio in addition to the video captured by the camera 210.

[0033] The cutout processing unit 123 performs a cutout process to cut out a predetermined range from the video data acquired by the video data acquisition unit 120. When the first housing 11 is in the first arrangement state, the cutout processing unit 123 may cut out a range that narrows the angle of view in at least the vertical direction, that is, the up-down direction, from the video data acquired by the video data acquisition unit 120. This is to cut out a video of the front of the vehicle, which is highly useful, when the first housing 11 is in the first arrangement state. The cutout processing unit 123 outputs the cutout video data to the buffer memory 121. FIG. 4 is a schematic diagram illustrating an example of the angle of view in the first arrangement of the first housing 11 of the vehicle recording device 10 according to the first embodiment. As shown in FIG. 4, when the first housing 11 is in the first arrangement state, the cutout processing unit 123 cuts out the vertical direction of the captured video data, that is, the vertical angle of view θ is in the range of about 90° to 120° with respect to the vertical angle of view of 180° in the first arrangement state. The vertical angle of view θ is the angle of view centered on the optical axis of the camera 210. An image with a vertical angle of view θ in the range of 90° to 120° is a range in which the vehicle is traveling and mainly captures the outside of the vehicle. Therefore, there is a high possibility that other vehicles or pedestrians in front of the vehicle will be captured. Images outside this angle of view capture, for example, the sky, the cabin ceiling, the dashboard, etc., and are less likely to capture other vehicles or pedestrians, making the images less useful.

[0034] When the first housing 11 is in the second arrangement, the cut-out processing unit 123 does not perform cut-out processing on the video data acquired by the video data acquisition unit 120. Fig. 5 is a schematic diagram illustrating an example of the angle of view in the second arrangement of the first housing 11 of the vehicular recording device 10 according to the first embodiment.

[0035] When the first housing 11 is in the second arrangement state, the cutout processing unit 123 may cut out a part of the video data acquired by the video data acquisition unit 120. This is to cut out a video of the front, interior, and rear of the vehicle, which is highly useful, when the first housing 11 is in the second arrangement state. When the first housing 11 is in the second arrangement state, the cutout processing unit 123 performs cutout processing on a range excluding the range of the angle of view Φ centered on the optical axis of the camera 210. This is because the range centered on the optical axis of the camera 210 captures, for example, the ceiling of the vehicle interior, and the usefulness of the video is low. FIG. 6 is a schematic diagram for explaining another example of the angle of view in the second arrangement of the first housing 11 of the vehicular recording device 10 according to the first embodiment.

[0036] The recording control unit 124 controls the recording unit 220 to record the video data filed by the video data processing unit 122. During a period in which the loop recording process is being performed, such as when the vehicle accessory power is ON, the recording control unit 124 records the video data filed by the video data processing unit 122 in the recording unit 220 as overwritable video data. More specifically, during a period in which the loop recording process is being performed, the recording control unit 124 continues to record the video data generated by the video data processing unit 122 in the recording unit 220, and when the capacity of the recording unit 220 becomes full, it overwrites the oldest video data with new video data and records it.

[0037] When the event detection section 133 detects an event, the recording control section 124 stores the video data for a predetermined period in the video data generated by the video data processing section 122 in the recording section 220 as event recording data that is prohibited from being overwritten.

[0038] When the first housing 11 is in the first placement state, the recording control unit 124 performs a monitoring operation while the vehicle is traveling. More specifically, when the first housing 11 is in the first placement state, the recording control unit 124 operates a traveling monitoring function, which is a monitoring operation while the vehicle is traveling, and saves the video data captured by the camera 210. The traveling monitoring function detects an event based on, for example, acceleration, and saves the video data using a loop recording process. The vehicle traveling refers to a state in which power is supplied to the vehicle recording control device 100 from the vehicle's accessory power source, or a state in which the vehicle engine or other power source is operating and the vehicle is being operated by the driver. Therefore, the vehicle traveling includes a state in which the vehicle is temporarily stopped in addition to a state in which the vehicle is traveling.

[0039] When the first housing 11 is in the second placement state, the recording control unit 124 performs a monitoring operation while the vehicle is parked. More specifically, when the first housing 11 is in the second placement state, the recording control unit 124 operates a parking monitoring function, which is a monitoring operation while the vehicle is parked, and stores the video data captured by the camera 210. The parking monitoring function detects an event, for example, based on motion detection, and stores the video data using a loop recording process. The parking monitoring function detects an event, for example, based on motion detection, and stores the video data for a predetermined period after the event detection. The vehicle being parked refers to a state in which power is not supplied from the accessory power source of the vehicle to the vehicle recording control device 100, a state in which the vehicle is stopped and the power of the engine or the like is stopped, the vehicle is not being operated by the driver, and a state in which the driver is not in the vehicle. The recording control unit 124 may control the video data acquisition unit 120 to cause the camera 210 to capture images at different frame rates when the first housing 11 is in the first placement state and when the first housing 11 is in the second placement state. For example, when first housing 11 is in the first position, video is captured at about 25 to 30 frames per second, and when first housing 11 is in the second position, video is captured at about 1 to 5 frames per second.

[0040] The playback control unit 125 controls the playback of the loop recorded video data or event recorded data recorded in the recording unit 220 based on a playback operation control signal output from the operation control unit 130 .

[0041] The operation control unit 130 acquires operation information of an operation accepted by the operation unit 240. For example, the operation control unit 130 acquires save operation information indicating a manual save operation of video data, play operation information indicating a play operation, or delete operation information indicating a delete operation of video data, and outputs a control signal. For example, the operation control unit 130 acquires end operation information indicating an operation to end loop recording, and outputs a control signal.

[0042] The display control unit 131 controls the display of video data on the display unit 250. The display control unit 131 outputs a video signal that causes the video data to be output to the display unit 250. More specifically, the display control unit 131 outputs a video signal that displays the video captured by the camera 210, or the loop recorded video data or the event recorded data recorded in the recording unit 220 by playing back the video. The display control unit 131 may cause the display unit 250 to display the video when the first housing 11 is in the first arrangement state, and may not cause the display unit 250 to display the video when the first housing 11 is in the second arrangement state.

[0043] The acceleration information acquisition unit 132 acquires information about the vehicle acceleration applied to the vehicle from the detection result of the acceleration sensor 260 .

[0044] When the first housing 11 is in the first placement state, the event detection unit 133 detects an event based on the acceleration applied to the vehicle. More specifically, when the first housing 11 is in the first placement state, in other words, when the travel monitoring function is being executed, the event detection unit 133 detects an event for the vehicle based on the detection result of the acceleration sensor 260 acquired by the acceleration information acquisition unit 132. When the acceleration detected by the acceleration sensor 260 is equal to or greater than a threshold, the event detection unit 133 detects it as an event.

[0045] When the first housing 11 is in the second placement state, the event detection unit 133 detects an event based on the detection of a moving object in the video captured by the camera 210. When the first housing 11 is in the second placement state, in other words, when the parking monitoring function is being executed, the event detection unit 133 detects the detection of a moving object in the vicinity of the vehicle as an event. More specifically, the event detection unit 133 performs image processing on the video data captured by the camera 210 to detect the moving object. The method of detecting a moving object from the video data may be any known technology and is not limited.

[0046] A moving object is, for example, a moving object such as a vehicle, a person, a falling object, or a flying object.

[0047] The position information acquisition unit 134 calculates the current position information of the vehicle based on the GNSS signal received by the GNSS receiving unit 270 using a known method.

[0048] The vehicle state determination unit 135 determines the state of the vehicle. The vehicle state refers to whether the vehicle is parked or running.

[0049] The vehicle state determination unit 135 determines whether the vehicle is parked. For example, when the accessory power supply of the vehicle is OFF, the vehicle state determination unit 135 determines that the vehicle is parked. More specifically, the vehicle state determination unit 135 determines that the vehicle is parked by acquiring a signal indicating that the accessory power supply of the vehicle has been OFF from a power supply information acquisition unit (not shown). For example, the vehicle state determination unit 135 determines that the vehicle is parked when the vehicle has stopped in a parking lot for a predetermined time or more. More specifically, the vehicle state determination unit 135 determines that the vehicle is parked when it is determined that the vehicle has stopped in a parking lot for a predetermined time or more based on the position information acquired by the position information acquisition unit 134, the map information stored in a map information storage unit (not shown), and information such as the vehicle speed acquired from a CAN (Controller Area Network) (not shown).

[0050] The vehicle state determination unit 135 determines whether the vehicle is running, including whether the vehicle is running or stopped. For example, when the accessory power supply of the vehicle is ON, the vehicle state determination unit 135 determines that the vehicle is running. The vehicle state determination unit 135 determines that the vehicle is running by acquiring a signal indicating that the accessory power supply of the vehicle is ON from a power supply information acquisition unit (not shown). For example, the vehicle state determination unit 135 determines that the vehicle is running when the vehicle has run for a predetermined time or more. More specifically, the vehicle state determination unit 135 determines that the vehicle is running when it is determined that the vehicle has run for a predetermined time or more based on at least one of the position information acquired by the position information acquisition unit 134 and information such as vehicle speed acquired from a CAN (Controller Area Network) (not shown).

[0051] The drive control unit 136 performs control to change the position of the first housing 11 based on the position of the first housing 11 and the determination result of the vehicle state determination unit 135.

[0052] When the first housing 11 is not in the first arrangement state and the vehicle state determination unit 135 determines that the vehicle is not parked, the drive control unit 136 performs control to change the first housing 11 to the first arrangement state. More specifically, when the vehicle is not parked, the drive control unit 136 outputs a control signal to the drive unit 280 to change the first housing 11 to the first arrangement state.

[0053] The drive control unit 136 performs control to change the first housing 11 to the second arrangement state when the vehicle state determination unit 135 determines that the vehicle is parked. More specifically, when the vehicle is parked, the drive control unit 136 outputs a control signal to the drive unit 280 to change the first housing 11 to the second arrangement state.

[0054] When the first housing 11 is in the first placement state, the vehicular recording device 10 constantly records video, i.e., performs so-called loop recording, and detects events based on acceleration. When the first housing 11 is in the second placement state, and power is supplied to the vehicular recording device 10 from the vehicle battery in addition to the accessory power supply, the vehicular recording device 10 constantly records video, i.e., performs so-called loop recording, and detects events by moving object detection.

[0055] <Processing in the Vehicle Recording Device> Next, the flow of processing in the vehicle recording control device 100 will be described with reference to Fig. 7. Fig. 7 is a flowchart showing the flow of processing in the vehicle recording device 10 according to the first embodiment. During startup of the vehicle recording device 10, the housing sensor 200 detects the state of the first housing 11 relative to the second housing 12.

[0056] The vehicle record control device 100 uses the vehicle state determination unit 135 to determine whether the vehicle is in a moving state (step SB101). If the vehicle state determination unit 135 determines that the vehicle is in a moving state (Yes in step SB101), the vehicle record control device 100 proceeds to step SB102. Since it has been determined that the vehicle is in a moving state in step SB101, in this state, the vehicle record control device 10 has a moving monitoring function operating. If the vehicle state determination unit 135 determines that the vehicle is not in a moving state (No in step SB101), the vehicle record control device 100 proceeds to step SB105. Since it has been determined that the vehicle is not in a moving state in step SB101, in this state, the vehicle is in a parked state, and the vehicle record control device 10 has a parking monitoring function operating.

[0057] If it is determined that the vehicle is in a driving state (Yes in step SB101), the vehicle recording control device 100 determines whether the vehicle has entered a parked state (step SB102). The vehicle recording control device 100 determines whether the vehicle has entered a parked state from a driving state using the vehicle state determination unit 135. If the vehicle state determination unit 135 determines that the vehicle has entered a parked state (Yes in step SB102), the vehicle recording control device 100 proceeds to step SB103. If the vehicle state determination unit 135 does not determine that the vehicle has entered a parked state (No in step SB102), the vehicle recording control device 100 proceeds to step SB108.

[0058] If it is determined that the vehicle is parked (Yes in step SB102), the vehicle recording control device 100 changes the first housing 11 to the second arrangement by the drive control unit 136 (step SB103). The vehicle recording control device 100 proceeds to step SB104.

[0059] The vehicle record control device 100 starts the parking monitoring function (step SB104). The parking monitoring function will be described later. The vehicle record control device 100 proceeds to step SB108.

[0060] If it is determined that the vehicle is not in a moving state (No in step SB101), that is, when the vehicle is in a parked state, it is determined whether the vehicle has entered a moving state (step SB105). The vehicle recording control device 100 determines whether the vehicle has entered a moving state from a parked state using the vehicle state determination unit 135. If the vehicle state determination unit 135 determines that the vehicle has entered a moving state (Yes in step SB105), the vehicle recording control device 100 proceeds to step SB106. If the vehicle state determination unit 135 does not determine that the vehicle has entered a moving state (No in step SB105), the vehicle recording control device 100 proceeds to step SB108.

[0061] If it is determined that the vehicle is moving (Yes in step SB105), the vehicle recording control device 100 changes the first housing 11 to the first arrangement (step SB106), and then proceeds to step SB107.

[0062] The vehicle record control device 100 starts the driving monitoring function (step SB107). The parking monitoring function will be described later. The vehicle record control device 100 proceeds to step SB108.

[0063] The vehicular recording control device 100 judges whether or not to end the process (step SB108). The end of the process is judged, for example, when the function of the vehicular recording device 10 is stopped by operating the operation unit 240. If it is judged that the process should be ended (Yes in step SB108), the process is ended. If it is judged that the process should not be ended (No in step SB108), the process of step SB101 is executed again.

[0064] Next, a process flow for detecting an event based on acceleration and storing video data using a loop recording process will be described with reference to Fig. 8 as an example of the traveling monitoring function. Fig. 8 is a flowchart showing the process flow in the vehicular recording device 10 according to the first embodiment. The process shown in Fig. 8 is executed when the traveling monitoring function starts operating in step SB107 of the flowchart shown in Fig. 7.

[0065] The vehicle record control device 100 starts normal recording (step S111). More specifically, the vehicle record control device 100 starts continuous recording by the camera 210, and starts event detection and loop recording based on acceleration. The vehicle record control device 100 generates loop recorded video data for each video of a predetermined period from the video data recorded in the buffer memory 121 by the video data processing unit 122. The vehicle record control device 100 causes the recording control unit 124 to record the loop recorded video data in the recording unit 220. The vehicle record control device 100 proceeds to step S112.

[0066] The vehicle record control device 100 determines whether an event has been detected by the event detection unit 133 (step S112). The vehicle record control device 100 detects an event for the vehicle by the event detection unit 133 based on the detection result of the acceleration sensor 260 acquired by the acceleration information acquisition unit 132. More specifically, the vehicle record control device 100 determines that an event has been detected when the event detection unit 133 detects acceleration equal to or greater than a threshold. If the event detection unit 133 detects an event (Yes in step S112), the vehicle record control device 100 proceeds to step S113. If the event detection unit 133 does not detect an event (No in step S112), the vehicle record control device 100 proceeds to step S114.

[0067] If an event is detected (Yes in step S112), the vehicular recording control device 100 stores the event record data (step S113). More specifically, the vehicular recording control device 100 uses the video data processing unit 122 to generate, as event record data, video data acquired from the camera 210 for a predetermined period before and after the event detection. Specifically, the vehicular recording control device 100 stores, from the loop recorded video data, video data for a predetermined period before and after the event detection as event record data. When it is determined that the predetermined time has elapsed, the vehicular recording control device 100 causes the recording control unit 124 to store the event record data generated by the video data processing unit 122 in the recording unit 220, and proceeds to step S114.

[0068] The vehicular recording control device 100 judges whether the traveling monitoring function has been terminated (step S114). The traveling monitoring function is terminated when, for example, the accessory power is turned off or the traveling monitoring function is stopped by operating the operation unit 240. If it is determined that the traveling monitoring function has been terminated (Yes in step S114), this process is terminated. If it is determined that the traveling monitoring function has not been terminated (No in step S114), the process of step S112 is executed again.

[0069] Next, a process flow for detecting an event by moving object detection and storing video data by loop recording process will be described with reference to Fig. 9 as an example of the parking monitoring function. Fig. 9 is a flowchart showing the process flow in the vehicular recording device 10 according to the first embodiment. The process shown in Fig. 9 is executed when the parking monitoring function starts operating in step SB104 of the flowchart shown in Fig. 7.

[0070] The vehicular recording control device 100 starts moving object detection (step S121). More specifically, the vehicular recording control device 100 starts capturing images with the camera 210 and starts event detection by moving object detection. The vehicular recording control device 100 starts event detection based on the video data captured by the camera 210 by the recording control unit 124. The vehicular recording control device 100 proceeds to step S122.

[0071] The vehicular recording control device 100 uses the event detection unit 133 to determine whether an event has been detected (step S122). The vehicular recording control device 100 detects, as an event, the detection of a moving object in the vicinity of the vehicle by the event detection unit 133. More specifically, if the event detection unit 133 detects a moving object in the vicinity of the vehicle, the vehicular recording control device 100 determines that an event has been detected (Yes in step S122) and proceeds to step S123. If the event detection unit 133 does not detect a moving object in the vicinity of the vehicle, the vehicular recording control device 100 determines that an event has not been detected (No in step S122) and proceeds to step S124.

[0072] If an event is detected (Yes in step S122), the vehicle record control device 100 saves the event record data (step S123). More specifically, the vehicle record control device 100 uses the video data processing unit 122 to generate event record data from video data acquired from the camera 210 for a predetermined period from when the event was detected. Specifically, recording of video data is started when an event is detected, and the video data for the predetermined period from when the event was detected is saved as event record data. The vehicle record control device 100 proceeds to step S124.

[0073] The vehicle recording control device 100 judges whether the parking monitoring function has been terminated (step S124). The parking monitoring function is terminated, for example, when the accessory power is turned ON or when the parking monitoring function is stopped by operating the operation unit 240. If it is determined in step S124 that the parking monitoring function has been terminated (Yes in step S124), this process is terminated. If it is determined that the parking monitoring function has not been terminated (No in step S124), the process of step S122 is executed again.

[0074] <Effects> As described above, in this embodiment, the first housing 11 is controlled to be in the first arrangement state when the vehicle is traveling, and to be in the second arrangement state when the vehicle is parked. In this embodiment, when the vehicle is traveling, the first housing 11 is in the first arrangement state, and the camera 210 captures the front of the vehicle. In this embodiment, when the vehicle is parked, the first housing 11 is in the second arrangement state, and the camera 210 captures a wide range including the interior of the vehicle, or the front and rear of the vehicle. In this embodiment, the first housing 11 can be appropriately arranged according to the state of the vehicle. In this embodiment, when the first housing 11 is in the first arrangement state, an event for the vehicle is detected based on the detection result of the acceleration sensor 260 acquired by the acceleration information acquisition unit 132. In this embodiment, when the first housing 11 is in the second arrangement state, the detection of a moving object around the vehicle is detected as an event. In this way, according to this embodiment, the vehicle can be appropriately used when traveling and when parking.

[0075] In this embodiment, the camera 210 is disposed on the surface 11a of the first housing 11, and the display unit 250 is disposed on the opposite side to the surface 11a. In this embodiment, even if the camera 210 is a camera capable of capturing images of a half-sky range, the display unit 250 can be positioned so as not to be included in the capturing range. According to this embodiment, the vertical size of the vehicular recording device 10 can be reduced, thereby reducing the possibility of obstructing the field of view.

[0076] In this embodiment, when the parking monitoring function is executed, the first housing 11 is in the second arrangement state, so that the display unit 250 is not included in the shooting range of the camera 210, and a wide range of video can be shot.

[0077] In this embodiment, when first housing 11 is in the first arrangement state, at least the vertical angle of view is narrowed for the image captured by camera 210. According to this embodiment, image data with an appropriate angle of view can be saved according to the arrangement of first housing 11.

[0078] In this embodiment, when the first housing 11 is in the first placement state, an event for the vehicle is detected based on the detection result of the acceleration sensor 260 acquired by the acceleration information acquisition unit 132. In this embodiment, when the first housing 11 is in the second placement state, the detection of a moving object in the vicinity of the vehicle is detected as an event. According to this embodiment, it can be appropriately used when the vehicle is traveling and when it is parked.

[0079] [Second embodiment] The vehicle recording device 10D according to this embodiment will be described with reference to FIG. 10, FIG. 11, and FIG. 12. FIG. 10 is a schematic diagram for explaining the vehicle recording device 10D according to the second embodiment. FIG. 11 is a block diagram showing a configuration example of the vehicle recording device 10D according to the second embodiment. FIG. 12 is a flowchart showing a flow of processing in the vehicle recording device 10D according to the second embodiment. The vehicle recording device 10D has a basic configuration similar to that of the vehicle recording device 10 of the first embodiment. The vehicle recording device 10D differs from the first embodiment in that it has a standard camera 310D in addition to the wide-angle camera 210D, and in the processing in the vehicle recording control device 100D. The wide-angle camera 210D is similar to the camera 210 of the first embodiment, and is a camera capable of capturing a half-sky circle with a viewing angle of 180°. The standard camera 310D captures a narrower viewing angle than the wide-angle camera 210D. The standard camera 310D captures a vertical range of, for example, about 90° to 120°.

[0080] The standard camera 310D is disposed near the wide-angle camera 210D facing the same direction. The standard camera 310D is disposed on the surface 11a of the first housing 11, similar to the wide-angle camera 210D. The standard camera 310D constantly captures video when the vehicle is traveling, and the wide-angle camera 210D constantly captures video when the vehicle is parked. The wide-angle camera 210D and the standard camera 310D output the captured video data to the video data acquisition unit 120D of the vehicle recording control device 100D. The video data is, for example, a moving image composed of images of 30 frames per second.

[0081] Video data acquisition section 120D acquires the video data output by wide-angle camera 210D and standard camera 310D, and outputs it to buffer memory 121D.

[0082] The video data processing unit 122D outputs the generated video data to a recording control unit 124D and a display control unit 131D.

[0083] Recording control section 124D controls switching between shooting with wide-angle camera 210D and shooting with standard camera 310D according to the arrangement of first housing 11.

[0084] When the first housing 11 is in the first placement state, the recording control unit 124D controls the standard camera 310D to capture and store video data. When the first housing 11 is in the first placement state, the recording control unit 124D operates the travel monitoring function and stores the video data captured by the standard camera 310D.

[0085] When the first housing 11 is in the second placement state, the recording control unit 124D controls the wide-angle camera 210D to capture and store video data. When the first housing 11 is in the second placement state, the recording control unit 124D operates the parking monitoring function and stores the video data captured by the wide-angle camera 210D.

[0086] Next, the process flow of the vehicle recording control device 100D will be described with reference to Fig. 12. Steps SB141, SB142, SB143, SB145, SB146, and SB148 in Fig. 12 are similar to steps SB101, SB102, SB103, SB105, SB106, and SB108 in Fig. 7.

[0087] When the first housing 11 is changed to the second arrangement state (step SB143), the vehicle recording control device 100D starts the driving monitoring function using the wide-angle camera 210D (step SB144). As a result, the parking monitoring function captures the surroundings of the vehicle with a wider angle of view than the standard angle of view. The vehicle recording control device 100D proceeds to step SB148.

[0088] When the first housing 11 is changed to the first arrangement state (step SB146), the vehicle recording control device 100D starts the running monitoring function using the standard camera 310D (step SB147). As a result, the running monitoring function captures the front of the vehicle with a standard angle of view. The vehicle recording control device 100D proceeds to step SB148.

[0089] As described above, in this embodiment, shooting by the standard camera 310D and shooting by the wide-angle camera 210D are switched depending on the arrangement of the first housing 11. In this embodiment, when the first housing 11 is in the first arrangement state, the standard camera 310D is used to execute the driving monitoring function. In this embodiment, when the first housing 11 is in the second arrangement state, the wide-angle camera 210D is used to execute the parking monitoring function. According to this embodiment, it can be appropriately used when the vehicle is driving and when it is parked.

In other words, the specific form of each device is not limited to that shown in the figure, and all or part of the devices may be functionally or physically distributed or integrated in any unit depending on the processing load and usage status of each device.

[0092] The configuration of the vehicle recording device 10 is realized, for example, as software by a program loaded into a memory.
