[0051] The power control unit 37 performs power control processing. The power control processing performed by the power control unit 37 is In output mode, measures are taken to suppress the unnecessary consumption of power from the internal power supply unit 26. That is logical. The power control unit 37 is comprised of the power supply control unit 370, the sensor control unit 371, and the communication control unit 372. It includes a shooting control unit 373 and a call control unit 374. The control unit 373 and the call control unit 374 have a timing function.

[0052] The power control unit 370 detects when the drive recorder 1 is removed from the mounting part 3 by the removal detection unit 21. If it is detected that the drive recorder has been removed, the power supply to drive recorder 1 will be cut off from the external power source. Switch to the power supply.

[0053] Furthermore, the power control unit 370 detects when the drive recorder 1 is removed by the removal detection unit 21. If it is detected that it has been removed from 3, and the drive recorder 1 is tilted at an angle greater than a predetermined angle Next, turn off the internal power. Note that when you turn on the power of drive recorder 1 again, The user presses the power button included in the operation button 11.

[0054] Here, when recording using drive recorder 1 in portable mode, Recorder 1 is assumed to be held by the user's hand with its orientation approximately horizontal. In other words, when taking photos using drive recorder 1 in portable mode, It is considered that the drive recorder 1 is not tilted at an angle greater than a predetermined angle (for example, 45 degrees). On the other hand, if the drive recorder 1 is tilted at an angle greater than a predetermined value, for example, if the power is on... If a user carries around dashcam 1 without realizing that it is still in that state... It's possible.

[0055] The sensor control unit 371 detects whether the drive recorder 1 is attached to the mounting part 3 by the removal detection unit 21. If it is detected that it has been removed, among the sensors included in the sensor unit 27, the acceleration sensor The operation of sensors other than sensor 113 is stopped, and the detection frequency of acceleration sensor 113 is reduced. To stop the sensor's operation here means to perform a control action that cuts off the power supply to the sensor. That is the case.

[0056] The communication control unit 372 stops communication with the outside when the communication power control conditions are met. The communication power control conditions are any of the following conditions: (i) If no object is captured in the image captured by the imaging unit 23 for a specified period of time or longer; (b) The dispersion of pixel values ​​corresponding to the colors contained in the image captured by the imaging unit 23 for a predetermined period of time or longer. If the value is less than or equal to the specified value; (h) If the drive recorder 1 is outside the communication range for a specified period of time or longer;

[0057] Users may forget to stop recording or otherwise be unaware that video is being recorded. If you carry Live Recorder 1 with you, Drive Recorder 1 will end up recording unnecessary videos. Since there is no need to send unnecessary videos to the server, if you are recording unnecessary videos... In drive recorder 1, communication with the outside world is stopped.

[0058] Under the above communication power control conditions, if an object is present in the image captured by the imaging unit 23 for a predetermined time or longer If no footage is being recorded, it is assumed that dashcam 1 is recording unnecessary video. Objects include the vehicle on which the drive recorder 1 is installed, other vehicles, people, and moving objects. This refers to objects or obstacles. Examples of obstacles include walls and guardrails. When determining the communication power control conditions, the drive recorder 1 is mounted as the above-mentioned object. Only vehicles that meet certain criteria may be handled.

[0059] For a predetermined time or longer, the dispersion of pixel values ​​corresponding to the colors contained in the image captured by the shooting unit 23 is When the color is below a certain level, for example, the color of the pixels in the image is almost black, or almost white, etc. This applies when there is only one color. When carrying the drive recorder 1 in portable mode. The lens of camera 19 is being covered by a hand, or dashcam 1 is in a bag. If this is the case, the color of the pixels in the image is thought to be almost entirely one color. If the colors appear almost entirely as one color, it is likely that dashcam 1 is recording unnecessary video. ru.

[0060] If drive recorder 1 is outside the communication range for a specified period of time, the recorded video will be sent to the server. Because it is not possible to send data, external communication will be temporarily suspended. Images taken during that period will be transmitted after drive recorder 1 is back in communication range. ru.

[0061] When the above-mentioned communication power control conditions are met, the imaging control unit 373 records to the imaging unit 23 Stop the video.

[0062] The call control unit 374 communicates the call unit while the drive recorder 1 is removed from the mounting unit 3. If a call to an external party is made for a specified period of time or longer by means of 35, a warning will be issued or the call will be terminated. Cut it.

[0063] [Power control processing] Figure 5 shows an example of the power control process according to this embodiment. The power control process is power This is performed by the control unit 37. The power control unit 37 controls, for example, the power supply of the drive recorder 1. While it is turned on, the power control process is repeatedly executed.

[0064] Step S10: The power control unit 370 detects the removal of the drive recorder 1 by the removal detection unit 21. It is determined whether or not it has been detected that the part has been removed from the mounting part 3. Here, the removal signal is detected. When the acquisition unit 300 acquires the removal signal A1 from the removal detection unit 21, the acquired removal The power supply control unit 370 outputs signal A1 to the power supply control unit 3. When the removal signal A1 is obtained from 00, the removal detection unit 21 detects the drive recorder It is determined that the device 1 has been removed from the mounting part 3.

[0065] The power control unit 370 detects when the drive recorder 1 is removed from the mounting part 3 by the removal detection unit 21. If it is determined that the device has been removed (step S10; YES), the power control unit 37 executes the process of step S20. Meanwhile, the power control unit 370 detects removal If 21 does not detect that the drive recorder 1 has been removed from the mounting part 3, If the determination is made (step S10; NO), the power control unit 37 terminates the power control process.

[0066] Step S20: The power control unit 370 supplies power to the drive recorder 1 from an external power source. Switch to internal power. The power control unit 370 turns off the external power supply and powers the internal power supply unit 26. To supply the source.

[0067] Step S30: The sensor control unit 371 controls the acceleration sensor among the sensors included in the sensor unit 27. The operation of sensors other than sensor 113 is stopped, and the detection frequency of acceleration sensor 113 is reduced. The sensor control unit 371 controls the sensors included in the sensor unit 27, excluding the acceleration sensor 113. The operation of the GPS receiver 18, geomagnetic sensor 114, and barometric pressure sensor 115 as sensors. Stop it.

[0068] Step S40: The sensor control unit 371 reduces the detection frequency of the acceleration sensor 113. The sensor control unit 371 determines the detection frequency when the drive recorder 1 is removed from the mounting part 3. To reduce it compared to before. With this, the power control unit 37 terminates the power control process.

[0069] (Variation 1) Figure 6 shows an example of power control processing according to Modification 1 of this embodiment. The processes in steps S110, S120, S130, and S140 are Steps S10, S20, S30, and S40 in Figure 5 Since this is the same as each of the other processes, the explanation will be omitted.

[0070] Step S150: The sensor control unit 371 determines that the drive recorder 1 has been running for a predetermined time or longer and that a predetermined time has been recorded. The sensor control unit 371 determines whether or not the angle is tilted above the specified angle. Tilt data B1 is obtained from 301. The sensor control unit 371 receives the acquired tilt data B1 If the angle indicated by is greater than or equal to a predetermined time, then drive recorder 1 will record for a predetermined time or longer. Furthermore, it is determined that the angle is tilted at a predetermined angle or greater. Here, a predetermined angle or greater is, for example, 45 degrees. The predetermined time is, for example, 5 seconds.

[0071] The sensor control unit 371 detects that the drive recorder 1 is tilted at a predetermined angle for a predetermined period of time or longer. If it is determined that it is present (step S150; YES), the power control unit 37 proceeds to step S160. The following process is executed. Meanwhile, the sensor control unit 371 determines if the drive recorder 1 has been running for a predetermined time or longer. If it is determined that the angle is not tilted above a predetermined value (step S150; NO), the power control unit 37 executes the process of step S170.

[0072] Step S160: The power control unit 370 turns off the internal power. Here the power control unit 37 0 stops the power supply to the internal power supply unit 26. Subsequently, the power control unit 37 controls the power Processing will now be terminated.

[0073] Step S170: The communication control unit 372 has been in the image captured by the imaging unit 23 for a predetermined time or longer. The communication control unit 372 determines whether or not an object has been photographed. Perform image analysis on the image. In this image analysis, the images of the objects contained in the image are, for example, For example, identification is performed based on template matching or machine learning. (Communication Control Unit 37) 2 obtains the image analysis results from the image analysis unit 32. The communication control unit 372 receives the image analysis results from the image analysis unit Based on the results of the image analysis by 32, if there is an object in the image captured by the imaging unit 23 for a predetermined time or longer Determine whether or not the body has been photographed.

[0074] The communication control unit 372 will notify the camera if an object is captured in the image captured by the camera unit 23 for a predetermined period of time or longer. If it is determined that there is no such person (step S170; YES), the process in step S180 is executed. Meanwhile, the communication control unit 372 will determine within a predetermined time if an object is in the image captured by the imaging unit 23. If it is determined that the image is being captured (step S170; NO), proceed to step S1100. Execute this.

[0075] Step S180: The communication control unit 372 stops communication with the outside. Here the communication control unit 3 72, for example, by stopping the supply of power from the internal power supply unit 26 to the communication unit 28 This will stop communication with the outside world.

[0076] Step S190: The shooting control unit 373 instructs the shooting unit 23 to stop recording. Here, communication is Unit 372 outputs a signal to the shooting control unit 373 indicating that it has stopped communicating with the outside world. When the shooting control unit 373 receives the signal, it controls the shooting unit 23 to stop recording. It outputs a signal. The shooting control unit 373 also controls the power supply from the internal power supply unit 26 to the shooting unit 23. Recording may be stopped by cutting off the power supply to the recording unit 23.

[0077] Step S1100: The communication control unit 372 has been in the image captured by the imaging unit 23 for a predetermined time or longer. Determine whether the variance of pixel values ​​corresponding to the colors included is below a predetermined value. Communication Control Unit 3 72 causes the image analysis unit 32 to perform image analysis of the image. The variance of pixel values ​​corresponding to the colors contained in the image is calculated. The communication control unit 372 performs image analysis. The image analysis results are obtained from unit 32. The communication control unit 372 receives the image analysis results from the image analysis unit 32. Based on the analysis results, the colors contained in the images captured by the imaging unit 23 for a predetermined period of time or longer correspond to the colors. It is determined whether the variance of the pixel values ​​is below a predetermined value.

[0078] The communication control unit 372 responds to the colors contained in the image captured by the imaging unit 23 for a predetermined period of time or longer. If it is determined that the variance of the pixel values ​​is less than or equal to a predetermined value (step S1100; YES), The process of step S180 is executed. Meanwhile, the communication control unit 372 will not process the imaging unit 2 for a predetermined time or longer. If it is determined that the variance of pixel values ​​corresponding to the colors contained in the image captured by 3 is not below a predetermined level, If (step S1100; NO), the power control unit 37 executes the process of step S1110. do.

[0079] Step S1110: The communication control unit 372 determines that the drive recorder 1 is within the communication range for a predetermined period of time or longer. It determines whether it is outside or not. The communication unit 28 determines the strength of the radio waves received by the communication antenna 16. Based on this, the system generates information indicating whether or not the drive recorder 1 is outside the communication range. Based on the information generated by the communication unit 28, 372 will activate the drive recorder for a predetermined period of time or longer. Determine whether or not device 1 is outside of the communication range.

[0080] The communication control unit 372 determined that the drive recorder 1 was outside the communication range for a predetermined period of time or longer. If (step S1110; YES), the process in step S180 is executed. Meanwhile, communication The control unit 372 determines that the drive recorder 1 is not outside the communication range for a predetermined period of time or longer. Step S1110; NO), the power control unit 37 terminates the power control process. With this, the power control unit 37 terminates the power control process.

[0081] Furthermore, in the power control process shown in Figure 6, steps S120 to S150 Each of the processes in step S110 may be omitted. In other words, in step S110, the removal detection unit 2 It was determined that the drive recorder 1 had been removed from the mounting part 3 by 1. In that case, the power control unit 370 may turn off the internal power supply. In other words, in that case, In Live Recorder 1, when in portable mode, the power is switched to the internal power supply, and then... The internal power supply is turned off dynamically.

[0082] Furthermore, the processing in step S170, step S1100, or step S1110 One or more of these can be omitted. In other words, it determines whether or not to stop communication with the outside world. To achieve this, one or more of the communication power control conditions may be omitted.

[0083] Furthermore, the processes in step S180 and step S190 are executed in a reversed order. This may be done. Also, the processing in step S190 may be omitted. In other words, step S 170, communication power control determined by step S1100 and step S1110 If one or more of the conditions are met, the process stops communication with the outside and records to the recording unit. Of the processes that stop the image, only the process that stops communication with the outside world may be executed.

[0084] Furthermore, the processing in step S160 is the same as the processing in step S180 or step S190. Replaced with the processing of step S180 and step S190, or both. It is also possible that the processing in step S180 and the processing in step S190 are performed in step S1 This can be replaced with process 60.

[0085] (Modification 2) Figure 7 shows an example of power control processing according to Modification 2 of this embodiment. Step S210, Step S220, Step S230, Step S240, Step S2 50, Step S260, Step S270, Step S280, Step S290, S The processes in steps S2100 and S2110 correspond to steps S110 and S in Figure 6. Step S120, Step S130, Step S140, Step S150, Step S 160, Step S170, Step S180, Step S190, Step S1100 Since this is the same as the process in step S1110, the explanation will be omitted. Note that the processing in step S260 is the same as the processing in step S280 or step S290. Replaced with the processing of one or both (steps S280 and S290). It is also possible to perform the processing in step S280 and step S290 in step S2 This can be replaced with process 60.

[0086] Step S2120: The call control unit 374 determines whether or not a call with an external party has been made for a predetermined period of time or longer. The call unit 35 outputs information indicating the call duration to the call control unit 374. The control unit 374, based on the information indicating the call duration output from the call unit 35, communicates with an external party. It is determined whether the procedure was performed for a predetermined period of time or longer.

[0087] If the call control unit 374 determines that a call with an external party has been made for a predetermined period of time or longer, (step S2120; YES), the process of step S2130 is executed. Meanwhile, the call control unit 374 However, if it is determined that no calls to external parties have been made for a specified period of time (step S2120; NO), the power control unit 37 terminates the power control process.

[0088] Step S2130: The call control unit 374 issues a warning. The call control unit 374 issues a warning unit 3 A warning is issued via 6 indicating that an external call has been ongoing for a predetermined period of time. Call control Unit 374 outputs a control signal to the warning unit 36 ​​to execute a warning process. Upon receiving the control signal, the device causes the audio output unit 29 to output a warning sound.

[0089] Note that the warning processing performed by the warning unit 36 ​​is not limited to those described above. 36 may cause the display unit 210 to display a warning string via the display control unit 34. Furthermore, if the drive recorder 1 is equipped with an LED lamp or other light-emitting part, the warning unit 36 As a warning, the light-emitting part may be made to blink. Furthermore, the warning unit 36 ​​performs warning processing, including outputting the aforementioned warning sound and a string of characters for the warning. One or more of the following may be combined: display and flashing of the light-emitting part. With this, the power control unit 37 terminates the power control process.

[0090] In the power control process shown in Figure 7, in step S2130, the call control unit 37 An example of when 4 issues a warning has been described, but it is not limited to this. The call control unit 374 Instead of issuing a warning, or along with a warning, you may disconnect the call to the outside. The call control unit 374 then instructs the call unit 35 to disconnect the call.

[0091] Furthermore, the shooting control unit 373 detects when the drive recorder 1 is removed by the removal detection unit 21. If it is detected that the device has been removed from unit 3, you may disable the long-press function for still image capture. i. As mentioned above, while the still image capture button is pressed, the camera 19 will take a picture at a predetermined timing Still images are continuously captured during shooting. Disable long-pressing the still image capture button. This means that when the still image capture button is pressed, regardless of how long it is pressed, one still image is captured. This involves controlling the camera to only capture still images.

[0092] Furthermore, the control unit 20 functions as a device installed in vehicles other than drive recorders. The equipment may be provided in such a way. For example, the equipment may be removable and used separately. It is a monitor.
