The first housing 11 is movable with respect to the second housing 12 fixed to the vehicle. In the present embodiment, the first housing 11 is movable with respect to the second housing 12 about the rotation axis AX. The second housing 12 supports the first housing 11 in the first and second arrangements. The first housing 11 has a first arrangement that is open to the second housing 12 as shown in FIG. 1 and a second arrangement that is closed to the second housing 12 as shown in FIG. Can be taken. The first housing 11 is used in the first arrangement state while the vehicle is running, and is used in the second arrangement state when the vehicle is parked. The first housing 11 is supported by the second housing 12 in the first and second arrangements. The first housing 11 in the first arrangement stands up against the second housing 12. The first housing 11 in the second arrangement is arranged so as to overlap the second housing 12.

The user manually changes the state of the first arrangement and the state of the second arrangement. For example, when the user uses the vehicle, that is, when the vehicle is driven, the state of the second arrangement is manually changed to the state of the first arrangement. Also, when the vehicle is finished in use, that is, when the vehicle is parked, the state of the first arrangement is manually changed to the state of the second arrangement.

The first housing 11 includes a camera 210 arranged on the surface 11a and a display unit 250 arranged on the side opposite to the surface 11a. When the first housing 11 is in the first arrangement, the camera 210 is arranged facing the front of the vehicle and facing the windshield, and the display unit 250 is arranged 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 arranged so as to overlap the surface 12a of the second housing 12. In the present embodiment, since the second housing 12 is arranged on the dashboard of the vehicle, the camera 210 is arranged facing upward when the first housing 11 is in the second arrangement. For example, when the second housing 12 is arranged on the ceiling of the vehicle interior of the vehicle, the camera 210 is arranged facing downward when the first housing 11 is in the second arrangement.

The vehicle recording device 10 may be a portable device that can be used in the vehicle, in addition to the device mounted on the vehicle. Further, the vehicle recording device 10 may be realized by including a function or a configuration of a device, a navigation device, or the like installed in advance in the vehicle.

It has 270 and a vehicle recording control device 100.

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 with respect to the second housing 12. The housing sensor 200 detects whether the first housing 11 is open or closed with respect 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 or not 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 record control device 100.

The camera 210 captures an image in the direction in which the camera 210 is pointed. In the present embodiment, the camera 210 is a camera capable of photographing a half-heavenly circumference of 180 °. The camera 210 is arranged on the surface 11a of the first housing 11. The camera 210 constantly captures images from the start to the stop of the engine and when the vehicle is parked. The camera 210 constantly captures an image regardless of whether the first housing 11 is in the first arrangement or the second arrangement. The camera 210 outputs the captured video data to the video data acquisition unit 120 of the vehicle recording control device 100. The video data is, for example, a moving image composed of an image of 30 frames per second.

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 (Flash Memory), or a recording unit such as a memory card. Alternatively, it may be an external recording unit wirelessly connected via a communication device (not shown). The recording unit 220 records loop recording video data or event recording data based on the control signal output from the recording control unit 124 of the vehicle recording control device 100.

The operation unit 240 can receive various operations on the vehicle recording device 10. For example, the operation unit 240 can accept an operation of manually saving the captured video data in the recording unit 220 as event recording data. For example, the operation unit 240 can accept an operation of reproducing the loop recorded video data or the event recording data recorded in the recording unit 220. For example, the operation unit 240 can accept an operation of erasing the event record 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 the operation information to the operation control unit 130 of the vehicle record control device 100.

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: Liquid Crystal Display) or an organic EL (Organic Electro-Luminence) display. The display unit 250 displays an image based on the image signal output from the display control unit 131 of the vehicle recording control device 100.

When the first housing 11 is in the second arrangement state, the display unit 250 overlaps the second housing 12 and the display surface is not exposed to the outside. The display unit 250 may display an image when the first housing 11 is in the first arrangement state, and may not display the image when the first housing 11 is in the second arrangement state.

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

The GNSS receiving unit 270 receives a GNSS signal from a GNSS satellite (not shown). The GNSS receiving unit 270 outputs the received radio wave signal to the position information acquisition unit 134 of the vehicle recording control device 100.

<Vehicle record control device>
The vehicle record control device 100 is, for example, an arithmetic processing unit (control device) configured by a CPU (Central Processing Unit) or the like. The vehicle record control device 100 includes an internal memory (not shown), and the internal memory is used for temporary storage of data in the vehicle record control device 100 and the like. The vehicle record control device 100 loads the stored program into the internal memory and executes the instruction included in the program. The vehicle recording control device 100 is cut out from the housing information acquisition unit 110, the state determination unit 111, the video data acquisition unit 120, the buffer memory 121, the video data processing unit 122, and the like, which are connected to the bus 100X. It has a processing unit 123, a recording control unit 124, a reproduction control unit 125, an operation control unit 130, a display control unit 131, an acceleration information acquisition unit 132, an event detection unit 133, and a position information acquisition unit 134. ..

The housing information acquisition unit 110 acquires housing information from the housing sensor 200.

The state determination unit 111 determines the state of the vehicle recording device 10 based on the housing information acquired by the housing information acquisition unit 110. The state determination unit 111 determines whether the first housing 11 is in the open state or the closed state with respect to the second housing 12 based on the housing information. The state determination unit 111 determines whether the first housing 11 is in the first arrangement state or the second arrangement state based on the housing information.

The video data acquisition unit 120 acquires video data taken by the camera 210. More specifically, the video data acquisition unit 120 acquires the video data output by the camera 210 and outputs it to the buffer memory 121. The video data acquisition unit 120 controls the shooting operation of the camera 210.

The buffer memory 121 is a memory for temporarily storing video data, and is a memory for a certain period of time acquired by the video data acquisition unit 120 or a predetermined time by the cutout processing unit 123 acquired by the video data acquisition unit 120. It is a memory that temporarily records the video data whose range has been cut out while updating it.

The video data processing unit 122 stores the video data temporarily stored in the buffer memory 121, for example, by H.I. Convert to any file format encoded by any codec such as 264 or MPEG-4 (Moving Picture Experts Group), for example MP4 format. 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 video data temporarily stored in the buffer memory 121 as a file for 60 seconds in the recording order. The video data processing unit 122 outputs the generated video data to the recording control unit 124. Further, the video data processing unit 122 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 the period 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.

The cutout processing unit 123 performs cutout processing for cutting 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, the cutting processing unit 123 narrows the vertical angle of view, which is at least the vertical direction, with respect to the video data acquired by the video data acquisition unit 120. You may cut out a wide range. This is to cut out an image taken in front of a highly useful vehicle when the first housing 11 is in the first arrangement state. The cutout processing unit 123 outputs the cut out video data to the buffer memory 121. FIG. 4 is a schematic view 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 cutting processing unit 123 has a vertical angle of view of the captured video data, that is, a vertical angle of view in the first arrangement state. Cut out so that the vertical angle of view θ is in the range of 90 ° or more and 120 ° or less with respect to 180 °. The angle of view θ in the vertical direction is an angle of view centered on the optical axis of the camera 210. The image in the range where the vertical angle of view θ is 90 ° or more and 120 ° or less is the traveling direction of the vehicle and is the range in which the outside of the vehicle is mainly photographed. Therefore, there is a high possibility that another vehicle or a pedestrian in front of the vehicle will be photographed. The image in the range outside this angle of view is less useful because, for example, the sky, the ceiling of the vehicle interior, the dashboard, and the like are photographed, and it is unlikely that another vehicle or a pedestrian is photographed.

When the first housing 11 is in the second arrangement, the cutout processing unit 123 does not perform cutout processing on the video data acquired by the video data acquisition unit 120. FIG. 5 is a schematic view illustrating an example of the angle of view in the second arrangement of the first housing 11 of the vehicle recording device 10 according to the first embodiment.

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

The recording control unit 124 controls the recording unit 220 to record the video data filed by the video data processing unit 122. During the period when the loop recording process is executed, such as when the accessory power supply of the vehicle is turned on, the recording control unit 124 uses the video data filed by the video data processing unit 122 as overwritable video data in the recording unit 220. Record in. More specifically, the recording control unit 124 continues to record the video data generated by the video data processing unit 122 in the recording unit 220 during the period in which the loop recording process is executed, and when the capacity of the recording unit 220 becomes full, the recording control unit 124 continues to record the video data. The oldest video data is overwritten with the new video data and recorded.

When the event detection unit 133 detects an event, the recording control unit 124 saves the video data for a predetermined period in the video data generated by the video data processing unit 122 in the recording unit 220 as event recording data for which overwriting is prohibited. do.

When the first housing 11 is in the first arrangement, the recording control unit 124 performs a monitoring operation while the vehicle is running. More specifically, when the first housing 11 is in the first arrangement, the recording control unit 124 operates a traveling monitoring function, which is a monitoring operation while the vehicle is traveling, and obtains video data captured by the camera 210. save. The travel monitoring function detects an event based on, for example, acceleration, and saves video data using loop recording processing. The running of the vehicle is a state in which power is supplied to the vehicle recording control device 100 from the accessory power supply of the vehicle, or a state in which the power of the vehicle engine or the like is operated and the vehicle is operated by the driver. .. Therefore, the running of the vehicle includes not only the state in which the vehicle is running but also the state in which the vehicle is temporarily stopped.

When the first housing 11 is in the second arrangement, 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 arrangement, the recording control unit 124 operates a parking monitoring function, which is a monitoring operation while the vehicle is parked, and obtains video data captured by the camera 210. save. The parking monitoring function detects an event based on, for example, motion detection, and saves video data using a loop recording process. The parking monitoring function detects an event based on, for example, motion detection, and saves video data for a predetermined period after the event is detected. When the vehicle is parked, the power is not supplied to the vehicle record control device 100 from the accessory power supply of the vehicle, or the vehicle is stopped and the power of the engine or the like is stopped, and the vehicle is not operated by the driver. The state, the state where the driver is not on board the vehicle. The recording control unit 124 controls the video data acquisition unit 120 depending on whether the first housing 11 is in the first arrangement state or the first housing 11 is in the second arrangement state, and the camera 210 has a different frame. You may have them shoot at a rate. For example, when the first housing 11 is in the first arrangement state, an image of about 25 to 30 frames per second is captured, and when the first housing 11 is in the second arrangement state, 1 to 5 per second. Have them shoot a frame-sized image.

The reproduction control unit 125 controls to reproduce the loop recorded video data or the event recording data recorded in the recording unit 220 based on the control signal of the reproduction operation output from the operation control unit 130.

The operation control unit 130 acquires the operation information of the operation received by the operation unit 240. For example, the operation control unit 130 acquires the save operation information indicating the manual save operation of the video data, the reproduction operation information indicating the reproduction operation, or the erasure operation information indicating the erasure operation of the video data, and outputs the control signal. For example, the operation control unit 130 acquires end operation information indicating an operation for ending loop recording and outputs a control signal.

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 for outputting the video data to the display unit 250. More specifically, the display control unit 131 outputs a video signal captured by the camera 210, or a video signal displayed by reproducing the loop recorded video data or event recording data recorded in the recording unit 220. The display control unit 131 causes the display unit 250 to display an image when the first housing 11 is in the first arrangement state, and causes the display unit 250 to display the image when the first housing 11 is in the second arrangement state. The image may not be displayed.

The acceleration information acquisition unit 132 acquires vehicle acceleration information added to the vehicle from the detection result of the acceleration sensor 260.

When the first housing 11 is in the first arrangement, 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 arrangement, the event detection unit 133 obtains the detection result of the acceleration sensor 260 acquired by the acceleration information acquisition unit 132 when the travel monitoring function is executed. Based on, the event for the vehicle is detected. When the event detection unit 133 detects an acceleration equal to or higher than a threshold value in the acceleration detected by the acceleration sensor 260, the event detection unit 133 detects it as an event.

When the first housing 11 is in the second arrangement, the event detection unit 133 detects an event based on motion detection for the image captured by the camera 210. When the first housing 11 is in the second arrangement, the event detection unit 133 detects as an event that a moving object in the vicinity of the vehicle is detected when the parking monitoring function is executed. More specifically, the event detection unit 133 performs image processing on the video data captured by the camera 210 to detect a moving object. Any known technique may be used to detect a moving object from the video data, and the method is not limited.

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

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

When the first housing 11 is in the first arrangement, the vehicle recording device 10 constantly records an image, so-called loop recording, and detects an event based on acceleration. The vehicle recording device 10 constantly records an image when the first housing 11 is in the second arrangement state and the vehicle recording device 10 is supplied with power from the vehicle battery other than the accessory power supply. The so-called loop recording is performed and the event is detected by detecting the moving object.

<Processing in vehicle recording device>
Next, the flow of processing in the vehicle record control device 100 will be described with reference to FIG. 7. FIG. 7 is a flowchart showing a processing flow in the vehicle recording device 10 according to the first embodiment. During the activation of the vehicle recording device 10, the housing sensor 200 detects the state of the first housing 11 with respect to the second housing 12.

The vehicle recording control device 100 determines whether or not the first housing 11 of the vehicle recording device 10 is in the first arrangement state by the state determination unit 111 (step SA101). The vehicle recording control device 100 determines the state of the vehicle recording device 10 by the state determination unit 111 based on the housing information acquired by the housing information acquisition unit 110. When the vehicle record control device 100 determines by the state determination unit 111 that the first housing 11 is in the first arrangement state (Yes in step SA101), the vehicle record control device 100 proceeds to step SA102. When the vehicle record control device 100 determines by the state determination unit 111 that the first housing 11 is not in the first arrangement (No in step SA101), the vehicle record control device 100 proceeds to step SA103.

When it is determined that the first housing 11 is in the first arrangement state (Yes in step SA101), the vehicle recording control device 100 starts the operation of the traveling monitoring function (step SA102). The processing of the travel monitoring function will be described later. The vehicle record control device 100 proceeds to step SA104.

When it is determined that the first housing 11 is not the first arrangement (No in step SA101), the vehicle record control device 100 starts the parking monitoring function (step SA103). The processing of the parking monitoring function will be described later. The vehicle record control device 100 proceeds to step SA104.

The vehicle recording control device 100 determines whether or not the arrangement of the first housing 11 of the vehicle recording device 10 has been changed by the state determination unit 111 (step SA104). The vehicle recording control device 100 determines whether or not the state of the vehicle recording device 10 has changed based on the housing information acquired by the housing information acquisition unit 110 by the state determination unit 111. When the vehicle record control device 100 determines that the arrangement of the first housing 11 has been changed by the state determination unit 111 (Yes in step SA104), the vehicle record control device 100 re-executes the process of step SA101. When the vehicle record control device 100 determines that the arrangement of the first housing 11 has not been changed by the state determination unit 111 (No in step SA104), the vehicle proceeds to step SA105.

The vehicle record control device 100 determines whether or not to end the process (step SA105). The end of the process is determined, for example, when the accessory power supply is turned off or the function of the vehicle recording device 10 is stopped by the operation of the operation unit 240. When it is determined that the process is terminated (Yes in step SA105), the present process is terminated. If it is determined that the processing has not been completed (No in step SA105), the processing in step SA104 is executed again.

Next, with reference to FIG. 8, as an example of the traveling monitoring function, a flow of processing for detecting an event based on acceleration and saving video data using loop recording processing will be described. FIG. 8 is a flowchart showing a processing flow in the vehicle recording device 10 according to the first embodiment. The process shown in FIG. 8 is executed when the travel monitoring function is started in step SA102 of the flowchart shown in FIG.

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 the event has been detected when the event detection unit 133 detects an acceleration equal to or higher than the threshold value. When the event is detected by the event detection unit 133 (Yes in step S112), the vehicle record control device 100 proceeds to step S113. If the event is not detected by the event detection unit 133 (No in step S112), the vehicle record control device 100 proceeds to step S114.

When an event is detected (Yes in step S112), the vehicle recording control device 100 saves the event recording data (step S113). More specifically, the vehicle recording control device 100 generates video data acquired from the camera 210 for a predetermined period before and after the event detection as event recording data by the video data processing unit 122. Specifically, from the loop recorded video data, the video data for a predetermined period before and after the event is detected is saved as the event recording data. When the vehicle recording control device 100 determines that the predetermined time has elapsed, the recording control unit 124 stores the event recording data generated by the video data processing unit 122 in the recording unit 220, and proceeds to step S114.

The vehicle record control device 100 determines whether or not the travel monitoring function has been terminated (step S114). The end of the travel monitoring function is determined, for example, when the accessory power supply is turned off or the travel monitoring function is stopped by the operation of the operation unit 240. When it is determined that the travel monitoring function has ended (Yes in step S114), this process ends. If it is determined that the travel monitoring function has not ended (No in step S114), the process of step S112 is executed again.

The vehicle record control device 100 detects as an event that a moving object in the vicinity of the vehicle is detected by the event detection unit 133. More specifically, when the event detection unit 133 detects a moving object around the vehicle, the vehicle record control device 100 determines that the 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 around the vehicle, the vehicle record control device 100 determines that the event is not detected (No in step S122), and proceeds to step S124.

When an event is detected (Yes in step S122), the vehicle recording control device 100 saves the event recording data (step S123). More specifically, the vehicle recording control device 100 generates video data for a predetermined period from the time when an event is detected acquired from the camera 210 by the video data processing unit 122 as event recording data. Specifically, recording of video data is started when an event is detected, and video data for a predetermined period from the time when the event is detected is stored as event recording data. The vehicle record control device 100 proceeds to step S124.

The vehicle record control device 100 determines whether or not the parking monitoring function has been terminated (step S124). The termination of the parking monitoring function is determined by the fact that the parking monitoring function is stopped by the operation of the operation unit 240 or the like. If it is determined in step S124 that the parking monitoring function has ended (Yes in step S124), this process ends. If it is determined that the parking monitoring function has not ended (No in step S124), the process of step S122 is executed again.
