Description

[Technical field]

[0001] The present invention relates to a recording control device and a program. [Background technology]

[0002] Patent Document 1 describes an electronic device with a camera that can be used both in-vehicle and portable and is removably mounted on a vehicle. With the technology described in Patent Document 1, when the electronic device with a camera that can be used both in-vehicle and portable is mounted on a vehicle and captures an image using the camera, a video is captured, and when the electronic device with a camera that can be used in-vehicle and portable is mounted on a vehicle and captures an image using the camera, a still image is captured. Incidentally, Patent Document 1 does not disclose whether or not the acceleration applied to the vehicle or the acceleration applied to the in-vehicle / portable camera-equipped electronic device is detected. In an electronic device such as the in-vehicle / portable camera-equipped electronic device described in Patent Document 1, if the electronic device is detached from the vehicle and acceleration is detected in the same way as when the electronic device is attached to the vehicle, and the occurrence of a vehicle accident is determined based on the detected acceleration, there is a risk that, for example, when the electronic device detached from the vehicle is operated by a user of the electronic device, it will be erroneously determined that a vehicle accident has occurred when in fact no vehicle accident has occurred. In other words, with the technology described in Patent Document 1, there is a risk that the in-vehicle / portable camera-equipped electronic device will not be properly controlled when the in-vehicle / portable camera-equipped electronic device is removed from the vehicle.

[0003] Currently, drive recorders with built-in batteries for parking monitoring are commercially available. Such drive recorders are installed inside a vehicle and used for parking monitoring. To use a drive recorder installed inside a vehicle after removing it from the vehicle, a battery with sufficient capacity is required because the drive recorder consumes a lot of power. To ensure sufficient capacity, the battery size must be increased, and therefore the size of the drive recorder body must also be increased. [Prior art documents] [Patent documents]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, a recording control device and a program according to an embodiment of the present invention will be described with reference to the accompanying drawings.

[0011] First Embodiment Fig. 1 is a diagram showing an example of a drive recorder R to which a recording control device 1 of a first embodiment is applied. Fig. 2 is a diagram showing an example of the recording control device 1 shown in Fig. 1. Fig. 3 is a diagram showing a comparison between an example of the functions of the drive recorder R when the drive recorder R is attached to a vehicle (normal operation) and an example of the functions of the drive recorder R when the drive recorder R is removed from the vehicle (when taken out). In the example shown in Fig. 1 to Fig. 3, the recording control device 1 is mounted on a drive recorder R. The drive recorder R is configured to be detachable from a vehicle. The drive recorder R includes a front camera RA, a rear camera RB, an in-camera RC, an infrared LED (light emitting diode) RD, a microphone RE, a speaker RF, an LCD (liquid crystal display) RG, a touch panel RH, a fan RI, a built-in battery RJ, a GPS (global positioning system) receiver RK, an acceleration sensor (shock sensor) RL, a LTE (Long Term Evolution) data communication unit RM, a VoIP (Voice over Internet Protocol) voice data communication unit RN, an ADAS (advanced driver assistance system) function unit RO, a DMS (driver monitoring system) function unit RP, a memory unit R1, a switch R2, and the recording control device 1.

[0012] The front camera RA captures an image of the area in front of the vehicle. The rear camera RB captures an image behind the vehicle. In the example shown in Fig. 1 to Fig. 3, the rear camera RB is provided in the drive recorder R, but in other examples, the rear camera RB may not be provided in the drive recorder R. For example, the drive recorder R may obtain image data behind the vehicle from a camera (not shown) for capturing an image behind the vehicle provided in the vehicle.

[0013] In the example shown in Figs. 1 to 3, the in-camera RC captures an image inside the vehicle (including an image of the driver). The infrared LED (light emitting diode) RD irradiates infrared light when the in-camera RC captures an image inside the vehicle, for example, at night. In the example shown in Figs. 1 to 3, the in-camera RC and the infrared LED RD are provided in the drive recorder R, but in other examples, the in-camera RC and the infrared LED RD do not have to be provided in the drive recorder R. For example, the drive recorder R may obtain image data inside the vehicle from an in-vehicle image capturing camera (not shown) provided in the vehicle.

[0014] In the example shown in Figs. 1 to 3, the microphone RE collects sounds inside the vehicle and converts them into audio data. The speaker RF outputs sounds such as guidance sounds and warning sounds. The LCD (liquid crystal display) RG can display images captured by the front camera RA or the like. The touch panel RH accepts input operations by the user of the drive recorder R or the like. The fan RI cools the components of the drive recorder R. The built-in battery RJ supplies power to the components of the drive recorder R when the drive recorder R is removed from the vehicle. The GPS receiver RK receives GPS signals transmitted from GPS satellites and performs functions such as detecting the position (positioning). The acceleration sensor RL detects the acceleration applied to the drive recorder R.

[0015] 1 to 3, the LTE data communication unit RM performs data communication using the LTE wireless communication standard. The VoIP voice data communication unit RN performs voice data communication by VoIP. In other words, the VoIP voice data communication unit RN is used for VoIP calls by users of the drive recorder R, etc. The ADAS function unit RO provides driving assistance functions to the driver (user of the drive recorder R) and the like. The functions of the advanced driving assistance system include, for example, a parking assistance function, a lane keeping assistance function, a collision avoidance assistance function, etc. In other words, the ADAS function unit RO performs, for example, parking assistance, lane keeping assistance, collision avoidance assistance, etc. The DMS function unit RP provides a driver (user of the drive recorder R) with a driver monitoring function. For example, the DMS function unit RP estimates whether the driver is looking away, yawning, dozing off (closing the eyes), etc., based on the image of the driver captured by the in-camera RC. When it is estimated that the driver is looking away, yawning, dozing off (closing the eyes), etc., the DMS function unit RP issues a warning, for example, by outputting a warning sound from the speaker RF.

[0016] The memory unit R1 stores various information. For example, the settings of the drive recorder R are stored in the memory unit R1. In addition, the memory unit R1 records images captured by the front camera RA, rear camera RB, and in-camera RC, audio data collected by the microphone RE and converted, and the like. The switch R2 has an attachment mode in which the drive recorder R is attached to the vehicle, and a removal mode in which the drive recorder R is removed from the vehicle. That is, when the drive recorder R is attached to the vehicle, the switch R2 is in the attachment mode, and when the drive recorder R is removed from the vehicle, the switch R2 is in the removal mode.

[0017] The recording control device 1 executes various controls. The recording control device 1 includes a front camera video recording control unit 1A, a rear camera video recording control unit 1B, an in-camera video recording control unit 1C, an infrared LED operation control unit 1D, a microphone voice recording control unit 1E, a speaker output control unit 1F, an LCD control unit 1G, a touch panel control unit 1H, a fan operation control unit 1I, a built-in battery power supply control unit 1J, a GPS signal acquisition control unit 1K, an acceleration sensor output signal acquisition control unit 1L, an LTE data communication control unit 1M, a VoIP voice data communication control unit 1N, an ADAS function control unit 1O, a DMS function control unit 1P, a front camera video playback control unit 1Q, a rear camera video playback control unit 1R, an in-camera video playback control unit 1S, a microphone voice playback control unit 1T, and a setting save / restore control unit 1U. The front camera image recording control unit 1A executes control to record an image of the area in front of the vehicle captured by the front camera RA in the storage unit R1.

[0018] The rear camera image recording control unit 1B executes control to record the image of the rear of the vehicle captured by the rear camera RB in the storage unit R1. In detail, the rear camera image recording control unit 1B executes control to determine whether or not to record the image of the rear of the vehicle captured by the rear camera RB in the storage unit R1. In an example in which the rear camera RB is not provided in the drive recorder R, the rear camera image recording control unit 1B executes control to determine whether or not to record the image data of the rear of the vehicle acquired by the drive recorder R in the storage unit R1. When the drive recorder R is removed from the vehicle, the rear camera image recording control unit 1B does not record the image captured by the rear camera RB (or the image data of the rear of the vehicle acquired by the drive recorder R) in the memory unit R1. On the other hand, when the drive recorder R is installed in the vehicle, the rear camera image recording control unit 1B records the image captured by the rear camera RB (or the image data of the rear of the vehicle acquired by the drive recorder R) in the memory unit R1.

[0019] 1 to 3, the in-camera video recording control unit 1C executes control to record the video of the inside of the vehicle captured by the in-camera RC in the storage unit R1. In detail, the in-camera video recording control unit 1C executes control to determine whether or not to record the video of the inside of the vehicle captured by the in-camera RC in the storage unit R1. The infrared LED operation control unit 1D executes control as to whether or not to operate the infrared LEDRD. In an example in which the in-camera RC and the infrared LEDRD are not provided in the drive recorder R, the in-camera video recording control unit 1C executes control to record the in-vehicle video data acquired by the drive recorder R in the storage unit R1. When the drive recorder R is removed from the vehicle, the in-camera video recording control unit 1C does not record the video captured by the in-camera RC (or the video data of the inside of the vehicle acquired by the drive recorder R) in the storage unit R1, and the infrared LED operation control unit 1D does not operate the infrared LED RD. This makes it possible to reduce power consumption and to make the built-in battery RJ smaller. In addition, it is possible to suppress heat generation from the drive recorder R removed from the vehicle. On the other hand, when a drive recorder R is installed in the vehicle, the in-camera image recording control unit 1C records the image captured by the in-camera RC (or the image data of the inside of the vehicle acquired by the drive recorder R) in the memory unit R1, and the infrared LED operation control unit 1D allows the operation of the infrared LED RD.

[0020] 1 to 3, a microphone voice recording control unit 1E controls the recording of in-vehicle voice data collected and converted by a microphone RE in a storage unit R1. A speaker output control unit 1F controls the voice output by a speaker RF. The LCD control unit 1G controls the display of images and the like by an LCD (liquid crystal display) RG. The touch panel control unit 1H controls the touch panel RH. Specifically, the touch panel control unit 1H generates coordinate information corresponding to a touch position on the touch panel RH by a user of the drive recorder R or the like, based on an output signal from the touch panel RH.

[0021] The fan operation control unit 1I executes control as to whether or not to operate the fan RI. When the drive recorder R is removed from the vehicle, the fan operation control unit 1I does not operate the fan RI. This makes it possible to reduce power consumption and reduce the size of the built-in battery RJ. On the other hand, when the drive recorder R is attached to the vehicle, the fan operation control unit 1I operates the fan RI. Therefore, components of the drive recorder R that generate a large amount of heat can be operated.

[0022] The built-in battery power supply control unit 1J executes control as to whether or not to supply power from the built-in battery RJ to the components of the drive recorder R. When the drive recorder R is removed from the vehicle, the built-in battery power supply control unit 1J executes the supply of power from the built-in battery RJ to the components of the drive recorder R.

[0023] The GPS signal acquisition control unit 1K executes control as to whether or not the GPS receiver RK receives GPS signals. When the drive recorder R is removed from the vehicle and when the drive recorder R is attached to the vehicle, the GPS signal acquisition control unit 1K causes the GPS receiver RK to receive GPS signals. The GPS receiver RK executes position detection (positioning). In another example, for example, when the drive recorder R is detached from the vehicle, the GPS signal acquisition control unit 1K may not cause the GPS receiver RK to receive GPS signals.

[0024] In the example shown in FIGS. 1 to 3, the acceleration sensor output signal acquisition control section 1L executes control as to whether or not to acquire the output signal of the acceleration sensor RL. When the drive recorder R is removed from the vehicle, the acceleration sensor output signal acquisition control unit 1L does not acquire the output signal of the acceleration sensor RL. Therefore, it is possible to suppress the risk of erroneously determining that an accident has occurred due to the output signal of the acceleration sensor RL being acquired when the drive recorder R is removed from the vehicle. In other words, it is possible to perform appropriate control when the drive recorder R is removed from the vehicle. On the other hand, when the drive recorder R is attached to the vehicle, the acceleration sensor output signal acquisition control section 1L acquires the output signal of the acceleration sensor RL.

[0025] 1 to 3, an LTE data communication control unit 1M controls whether or not to cause an LTE data communication unit RM to perform data communication using the LTE wireless communication standard. A VoIP voice data communication control unit 1N controls whether or not to cause a VoIP voice data communication unit RN to perform voice data communication by VoIP.

[0026] The ADAS function control unit 1O executes control as to whether or not to cause the ADAS function unit RO to provide a driving assistance function. When the drive recorder R is removed from the vehicle, the ADAS function control unit 1O does not allow the ADAS function unit RO to provide the driving assistance function. In other words, the driving assistance function that requires complex calculation is not provided. As a result, power consumption can be reduced and the built-in battery RJ can be made smaller. In addition, heat generation of the drive recorder R removed from the vehicle can be reduced. On the other hand, when the drive recorder R is installed in the vehicle, the ADAS function control unit 1O causes the ADAS function unit RO to provide a driving assistance function. That is, the ADAS function unit RO performs driving assistance such as parking assistance, lane keeping assistance, and collision avoidance assistance.

[0027] The DMS function control unit 1P executes control as to whether or not to cause the DMS function unit RP to provide the driver monitoring function. When the drive recorder R is removed from the vehicle, the DMS function control unit 1P does not allow the DMS function unit RP to provide the driver monitoring function. In other words, the driver monitoring function that requires complex calculations is not provided. As a result, power consumption can be reduced and the built-in battery RJ can be made smaller. In addition, heat generation from the drive recorder R removed from the vehicle can be reduced. On the other hand, when the drive recorder R is installed in the vehicle, the DMS function control unit 1P causes the DMS function unit RP to provide a driver monitoring function. That is, the DMS function unit RP estimates, for example, whether the driver is looking away, yawning, or dozing, and issues an alarm as necessary.

[0028] The front camera image playback control unit 1Q performs control to play back the image of the front of the vehicle (image of the front of the vehicle captured by the front camera RA) recorded in the memory unit R1 by the front camera image recording control unit 1A, for example, in response to an input operation by a user of the drive recorder R received by the touch panel RH. The rear camera image playback control unit 1R performs control to play back the image of the rear of the vehicle (image of the rear of the vehicle captured by the rear camera RB) recorded in the memory unit R1 by the rear camera image recording control unit 1B, for example, in response to an input operation by a user of the drive recorder R received by the touch panel RH. The in-camera video playback control unit 1S executes control to play back the video of the interior of the vehicle (video of the interior of the vehicle captured by the in-camera RC) recorded in the memory unit R1 by the in-camera video recording control unit 1C in response to an input operation by a user of the drive recorder R, for example, received by the touch panel RH. The microphone audio playback control unit 1T performs control to convert the audio data recorded in the memory unit R1 by the microphone audio recording control unit 1E and output the audio from the speaker RF, for example, in response to an input operation by a user of the drive recorder R received by the touch panel RH.

[0029] The setting save / restore control unit 1U performs control to save the settings of the drive recorder R in the storage unit R1 and control to restore the settings of the drive recorder R saved in the storage unit R1. When the drive recorder R is removed from the vehicle (that is, when the switch R2 goes into the removal mode), the setting save / restore control unit 1U saves the setting of the drive recorder R at that time in the storage unit R1. When the drive recorder R is attached to the vehicle (i.e., when the switch R2 is set to the attachment mode), the setting save / restore control unit 1U instantly restores the settings of the drive recorder R that were saved in the storage unit R1 when the drive recorder R was removed from the vehicle. This makes it possible to reduce the time required for setting when the drive recorder R is attached to the vehicle.

[0030] 1 to 3, the settings of the drive recorder R that are stored in the storage unit R1 when the drive recorder R is removed from the vehicle and are restored when the drive recorder R is attached to the vehicle include the white balance settings of the front camera RA, the rear camera RB, and the in-camera RC. This is because the environment is different when the drive recorder R is removed from the vehicle and when the drive recorder R is attached to the vehicle, and it takes time to adjust the white balance from when the drive recorder R is removed from the vehicle to when the drive recorder R is attached to the vehicle. In another example, when the drive recorder R is removed from the vehicle, the white balance settings of at least one of the front camera RA, the rear camera RB, and the in-camera RC may not be stored in the storage unit R1.

[0031] In the above-mentioned example in which the GPS signal acquisition control unit 1K does not allow the GPS receiver RK to receive GPS signals when the drive recorder R is removed from the vehicle, the settings of the drive recorder R that are stored in the storage unit R1 when the drive recorder R is removed from the vehicle and are restored when the drive recorder R is attached to the vehicle include settings for the GPS receiver RK to receive GPS signals. This is because the GPS receiver RK does not receive GPS signals when the drive recorder R is removed from the vehicle, and the GPS receiver RK receives GPS signals when the drive recorder R is attached to the vehicle, and therefore the environments are different between the two, and it would take time to set the GPS receiver RK to receive GPS signals when the drive recorder R is attached to the vehicle. In another example, when the drive recorder R is removed from the vehicle, the setting for the GPS receiver RK to receive a GPS signal does not have to be saved in the storage unit R1.

[0032] 1 to 3, the settings of the drive recorder R that are saved in the storage unit R1 when the drive recorder R is removed from the vehicle and restored when the drive recorder R is attached to the vehicle include settings for the ADAS function unit RO to provide a driving assistance function. This is because the ADAS function unit RO does not provide a driving assistance function when the drive recorder R is removed from the vehicle, and the ADAS function unit RO provides a driving assistance function when the drive recorder R is attached to the vehicle, and therefore the environments are different between the two, and it takes time to perform settings (initialization) for the ADAS function unit RO to provide a driving assistance function when the drive recorder R is attached to the vehicle. In another example, when the drive recorder R is removed from the vehicle, the setting for the ADAS function unit RO to provide the driving assistance function may not be stored in the memory unit R1.

[0033] 4 and 5 are flowcharts illustrating an example of processing executed in the recording control device 1 of the first embodiment. 4 and 5, in step S10, the recording control device 1 determines whether or not the switch R2 is in the removal mode. If the switch R2 is in the removal mode, the process proceeds to step S11A. If the switch R2 is in the attachment mode, the process proceeds to step S11B.

[0034] In step S11A, the setting save and restore control unit 1U saves the setting of the drive recorder R in the storage unit R1. Also, in step S12A, the front camera image recording control unit 1A records the image of the area in front of the vehicle captured by the front camera RA in the storage unit R1. Also, in step S13A, the rear camera image recording control unit 1B does not record the image captured by the rear camera RB (or the image data of the rear of the vehicle acquired by the drive recorder R) in the storage unit R1. Also, in step S14A, the in-camera video recording control unit 1C does not record the video captured by the in-camera RC (or the video data of the inside of the vehicle acquired by the drive recorder R) in the storage unit R1. Also, in step S15A, the infrared LED operation control section 1D does not operate the infrared LEDRD.

[0035] Also, in step S16A, the microphone voice recording control unit 1E records in the storage unit R1 the voice data inside the vehicle that has been collected and converted by the microphone RE. Furthermore, in step S17A, the speaker output control unit 1F executes control of audio output by the speaker RF. Furthermore, in step S18A, the LCD control section 1G controls the display of images and the like by an LCD (liquid crystal display) RG. Furthermore, in step S19A, the touch panel control unit 1H executes control of the touch panel RH. Moreover, in step S20A, the fan operation control unit 1I does not operate the fan RI.

[0036] Furthermore, in step S21A, the built-in battery power supply control unit 1J supplies power to the components of the drive recorder R from the built-in battery RJ. Also, in step S22A, the GPS signal acquisition control unit 1K causes the GPS receiver RK to receive GPS signals. Furthermore, in step S23A, the acceleration sensor output signal acquisition control section 1L does not acquire the output signal of the acceleration sensor RL. Also, in step S24A, the LTE data communication control unit 1M causes the LTE data communication unit RM to perform data communication using the LTE wireless communication standard. Also, in step S25A, the VoIP voice data communication control unit 1N causes the VoIP voice data communication unit RN to perform voice data communication by VoIP. Moreover, in step S26A, the ADAS function control unit 1O does not cause the ADAS function unit RO to provide the driving assistance function. Also, in step S27A, the DMS function control unit 1P does not allow the DMS function unit RP to provide the driver monitoring function.

[0037] In step S11B, the setting save / restore control unit 1U restores the setting of the drive recorder R that was saved in the storage unit R1 in step S11A. Also, in step S12B, the front camera image recording control unit 1A records the image of the area in front of the vehicle captured by the front camera RA in the storage unit R1. Furthermore, in step S13B, the rear camera image recording control unit 1B records the image captured by the rear camera RB (or the image data of the rear of the vehicle acquired by the drive recorder R) in the storage unit R1. Also, in step S14B, the in-camera video recording control unit 1C records the video captured by the in-camera RC (or the video data of the inside of the vehicle acquired by the drive recorder R) in the storage unit R1. Furthermore, in step S15B, the infrared LED operation control section 1D permits the operation of the infrared LED RD.

[0038] Also, in step S16B, the microphone voice recording control unit 1E records in the storage unit R1 the voice data inside the vehicle that has been collected and converted by the microphone RE. Furthermore, in step S17B, the speaker output control unit 1F executes control of the audio output by the speaker RF. Furthermore, in step S18B, the LCD control section 1G controls the display of images and the like by an LCD (liquid crystal display) RG. Furthermore, in step S19B, the touch panel control unit 1H executes control of the touch panel RH. Furthermore, in step S20B, the fan operation control unit 1I operates the fan RI.

[0039] Furthermore, in step S21B, the built-in battery power supply control unit 1J does not supply power to the components of the drive recorder R from the built-in battery RJ. Furthermore, in step S22B, the GPS signal acquisition control unit 1K causes the GPS receiver RK to receive GPS signals. Furthermore, in step S23B, the acceleration sensor output signal acquisition control section 1L acquires the output signal of the acceleration sensor RL. Also, in step S24B, the LTE data communication control unit 1M causes the LTE data communication unit RM to perform data communication using the LTE wireless communication standard. Also, in step S25B, the VoIP voice data communication control unit 1N causes the VoIP voice data communication unit RN to perform voice data communication by VoIP. Furthermore, in step S26B, the ADAS function control unit 1O causes the ADAS function unit RO to provide the driving assistance function. Furthermore, in step S27A, the DMS function control unit 1P causes the DMS function unit RP to provide the driver monitoring function.

[0040] FIG. 6 is a diagram for explaining an example of the setting data of the drive recorder R when the mode of the switch R2 is switched between the attachment mode and the removal mode. In the example shown in FIG. 6, when the routine shown in FIG. 6 starts, the switch R2 goes into the attachment mode (i.e., the drive recorder R is used while attached to the vehicle), and the drive recorder R performs normal recording (i.e., the recording control device 1 executes the processes of steps S12B to S27B in FIGS. 4 and 5, etc.). Next, in step S1, the switch R2 goes into the removal mode (that is, an operation to remove the drive recorder R from the vehicle is performed by the user of the drive recorder R). Therefore, in step S2, the setting save / restore control unit 1U holds the setting data (normal recording data) when the drive recorder R was performing normal recording, and saves (stores) the setting data (normal recording data) in the storage unit R1. In detail, camera image information such as white balance setting data of the front camera RA, rear camera RB, and in-camera RC is saved in the storage unit R1. In addition, other setting data such as setting data for the ADAS function unit RO to provide a driving assistance function is saved in the storage unit R1.

[0041] Next, the drive recorder R removed from the vehicle is used by the user of the drive recorder R. In detail, during the use of the drive recorder R removed from the vehicle, in step S3, the settings of the drive recorder R are updated (i.e., the settings of the drive recorder R are changed). For example, the white balance setting of the front camera RA is changed by using the front camera RA. Furthermore, during the use of the drive recorder R removed from the vehicle, the ADAS function unit RO does not provide the driving assistance function. Therefore, in step S3, the setting of the drive recorder R is updated to a setting that does not allow the ADAS function unit RO to provide the driving assistance function.

[0042] Next, in step S4, the drive recorder R is attached to the vehicle, and the mode of the switch R2 becomes the attachment mode. Furthermore, in step S4, the setting save / restore control unit 1U restores the setting of the drive recorder R that was saved in the storage unit R1 in step S2. In detail, in step S4, the camera image information such as the white balance setting data of the front camera RA, the rear camera RB, and the in-camera RC stored in the storage unit R1 in step S2 is restored. Furthermore, in step S4, other setting data such as setting data for the ADAS function unit RO to provide a driving assistance function stored in the storage unit R1 in step S2 is restored.

[0043] As described above, in the drive recorder R to which the recording control device 1 of the first embodiment is applied, when the drive recorder R is removed from the vehicle, the circuitry is stopped and restricted, for example, the functions used by the drive recorder R are stopped. This makes it possible to reduce the amount of power supplied from the built-in battery RJ, thereby extending the life of the built-in battery RJ. In addition, the power consumption of the drive recorder R can be reduced, and heat generation from the exterior surface of the main body of the drive recorder R can be reduced, eliminating the risk of low-temperature burns to users of the drive recorder R. Furthermore, since unused circuits are not left unconnected, there is no indefinite data, and malfunctions can be suppressed. As described above, the recording control device 1 of the first embodiment is mounted on a drive recorder R that is detachable from a vehicle, and includes a specific function control unit that controls whether or not a specific function unit that provides a specific function other than recording is caused to provide the specific function. It can also be said that the specific function control unit does not cause the specific function unit to provide the specific function when the drive recorder R is detached from the vehicle, and causes the specific function unit to provide the specific function when the drive recorder R is attached to the vehicle. The specific functions include, for example, a function to acquire an output signal from an acceleration sensor RL that detects acceleration applied to the vehicle or acceleration applied to the drive recorder R, a function to have a GPS receiver RK receive a GPS signal, a driving assistance function by an ADAS functional unit RO, a driver monitoring function by a DMS functional unit RP, a function to cool the drive recorder R by a fan RI, a function to record images captured by a rear camera RB for capturing images behind the vehicle, and a function to record images captured by an in-camera RC for capturing images inside the vehicle. "The function of causing the GPS receiver RK to receive GPS signals" does not have to be included in the "specific functions." The recording control device 1 of the first embodiment may prohibit the drive recorder R from playing back recorded moving images when the drive recorder R is detached from the vehicle.

[0044] In another example of a drive recorder R to which the recording control device 1 of the first embodiment is applied, when the temperature of the exterior surface of the drive recorder R becomes equal to or higher than a threshold value (e.g., 40°C, 43°C, 45°C, etc.) while the drive recorder R is removed from the vehicle and in use, the recording control device 1 may stop functions other than those related to image capture of the drive recorder R, and control the quality of recording to a predetermined level or lower until the temperature of the exterior surface of the drive recorder R becomes lower than the threshold value.

[0045] <Second embodiment> A second embodiment of the recording control device and program of the present invention will now be described. Except for the points described below, the recording control device 1 of the second embodiment is configured similarly to the recording control device 1 of the first embodiment described above. Therefore, the recording control device 1 of the second embodiment can achieve the same effects as the recording control device 1 of the first embodiment described above, except for the points described below.

[0046] As described above, in the drive recorder R to which the recording control device 1 of the first embodiment is applied, the drive recorder R is provided with an acceleration sensor RL. On the other hand, in a drive recorder R to which the recording control device 1 of the second embodiment is applied, an acceleration sensor RL is not provided in the drive recorder R, and the drive recorder R acquires an output signal of an acceleration sensor provided in the vehicle (i.e., an acceleration sensor that detects the acceleration applied to the vehicle).

[0047] In a drive recorder R to which the recording control device 1 of the second embodiment is applied, an acceleration sensor output signal acquisition control section 1L executes control as to whether or not to acquire an output signal from an acceleration sensor provided in a vehicle. When the drive recorder R is removed from the vehicle, the acceleration sensor output signal acquisition control unit 1L does not acquire the output signal of the acceleration sensor provided in the vehicle. Therefore, it is possible to suppress the risk of erroneously determining that an accident has occurred due to the output signal of the acceleration sensor being acquired when the drive recorder R is removed from the vehicle. In other words, it is possible to perform appropriate control when the drive recorder R is removed from the vehicle. On the other hand, when the drive recorder R is attached to the vehicle, the acceleration sensor output signal acquisition control section 1L acquires an output signal of an acceleration sensor provided in the vehicle.

[0048] Although the present invention has been described above using the embodiments, the present invention is not limited to these embodiments, and various modifications and substitutions can be made without departing from the scope of the present invention. The configurations described in the above-mentioned embodiments and examples may be appropriately combined.

[0049] Note that all or part of the functions of each unit of the recording control device 1 or drive recorder R in the above-mentioned embodiment may be realized by recording a program for realizing these functions on a computer-readable recording medium, and having a computer system read and execute the program recorded on the recording medium. Note that the term "computer system" here includes hardware such as the OS and peripheral devices. In addition, the term "computer-readable recording medium" refers to portable media such as flexible disks, optical magnetic disks, ROMs, and CD-ROMs, and storage units such as hard disks built into computer systems. Furthermore, the term "computer-readable recording medium" may also include those that dynamically hold a program for a short period of time, such as a communication line when transmitting a program via a network such as the Internet or a communication line such as a telephone line, and those that hold a program for a certain period of time, such as a volatile memory inside a computer system that serves as a server or client in such cases. Furthermore, the above program may be one that realizes part of the above-mentioned functions, or may be one that can realize the above-mentioned functions in combination with a program already recorded in the computer system.
