[0009] Hereinafter, with reference to the accompanying drawings, embodiments of an in-vehicle device, an audio processing method, and an audio processing system will be described in detail. Note that the present invention is not limited to the embodiments described below. The in-vehicle device according to the embodiments is a drive recorder that is mounted on a vehicle and captures and records images of the area around the vehicle (hereinafter referred to as "exterior vehicle images") and collects and records audio from within the vehicle cabin (hereinafter referred to as "in-vehicle audio").

[0010] [1. Example of in-vehicle device configuration] First, a configuration example of an in-vehicle device 1 according to an embodiment will be described with reference to Fig. 1. Fig. 1 is an explanatory diagram showing a configuration example of an in-vehicle device 1 according to an embodiment.

[0011] As shown in FIG. 1, the vehicle-mounted device 1 includes cameras 20 and 21, a sensor 22, a microphone 23, a controller 3, and a storage 4. The camera 20 is an imaging device that captures video of the interior of the vehicle (hereinafter referred to as "in-vehicle video 50"). The camera 21 is an imaging device that captures video of the exterior of the vehicle 51. The sensor 22 is a detection device that detects an impact applied to the vehicle in which the vehicle-mounted device 1 is mounted. The microphone 23 is a sound collection device that collects in-vehicle audio 52.

[0012] The controller 3 includes a microcomputer having a CPU (Central Processing Unit), ROM (Read Only Memory), RAM (Random Access Memory), etc., and various circuits. The controller 3 controls the overall operation of the in-vehicle device 1 by having the CPU execute a program stored in the ROM using the RAM as a working area.

[0013] The controller 3 may be partially or entirely configured with hardware such as an ASIC (Application Specific Integrated Circuit) or an FPGA (Field Programmable Gate Array).

[0014] The storage 4 is an information storage device such as a data flash, and stores an in-vehicle image 50, an outside-vehicle image 51, an in-vehicle voice 52, and user information 53. The user information 53 includes voice information 54 and a facial image 55. The voice information 54 is information about the voice of the user 10 of the in-vehicle device 1 that is registered in advance. The voice information 54 includes, for example, voiceprint information and voice frequency information of the user 10. The facial image 55 is an image of the face of the user 10.

[0015] The user 10 can use a predetermined application program (hereinafter referred to as an "app") installed on a terminal device such as a smartphone (hereinafter referred to as a "user terminal 11") to record his / her own voice and capture an image 55 of his / her face, and transmit the image 55 from the user terminal 11 to the in-vehicle device 1. The controller 3 stores and registers the user information 53 received from the user terminal 11 in the storage 4.

[0016] When the in-vehicle device 1 is started, the controller 3 records the in-vehicle image 50 input from the camera 20, the outside-vehicle image 51 input from the camera 21, and the in-vehicle audio 52 input from the microphone 23 in the storage 4. The controller 3 overwrites and records the outside-vehicle image 51 and the in-vehicle audio 52 in the storage 4 every predetermined time (for example, every two hours).

[0017] When an audio output trigger is activated, the controller 3 outputs the vehicle exterior image 51 and the vehicle interior audio 52. The vehicle-mounted device 1 activates the audio output trigger, for example, when it receives an output request for recorded audio from an app on the user terminal 11. The vehicle-mounted device 1 may be configured to activate the audio output trigger, for example, when a predetermined output operation is performed on an operation unit (not shown).

[0018] In this way, the vehicle-mounted device 1 can record and output the outside vehicle image 51 and the inside vehicle audio 52, and thereby contribute to clarifying the cause of the accident, for example, in the event of a vehicle accident, by outputting the recorded outside vehicle image 51 and inside vehicle audio 52.

[0019] However, some users 10 of the in-vehicle device may not want their in-vehicle voices 52 to be heard by third parties from the viewpoint of protecting their privacy. For this reason, some in-vehicle devices allow the recording function to be turned off. However, when the recording function is turned off, the in-vehicle device cannot record voice information 54 other than conversations within the vehicle that are important for determining the cause of the accident.

[0020] Therefore, the in-vehicle device 1 according to the embodiment has a configuration that can record important in-vehicle voice 52 while protecting the privacy of the user 10. Specifically, the controller 3 of the in-vehicle device 1 records the in-vehicle voice 52 and detects the voice of the user 10 that corresponds to pre-registered voice information 54 of the user 10 from the recorded in-vehicle voice 52. Then, the controller 3 processes the detected voice of the user 10.

[0021] According to the vehicle-mounted device 1, the controller 3 processes the recorded voice of the user 10 so that the user 10 cannot be identified from the voice, thereby protecting the privacy of the user 10 and recording important in-vehicle voice 52.

[0022] At this time, the controller 3 processes the voice of the user 10 so as to erase the detected voice of the user 10. For example, the controller 3 erases the voice of the user 10 from the in-vehicle voice 52 by synthesizing the in-vehicle voice 52 with an antiphase sound of the speech voice of the user 10. This allows the in-vehicle device 1 to record the in-vehicle voice 52 other than the voice of the user 10, thereby enabling the important in-vehicle voice 52 to be recorded while reliably protecting the privacy of the user 10.

[0023] Furthermore, the controller 3 processes the detected voice of the user 10 by performing a voice change process so as to convert the voice of the user 10 into a voice that does not identify the speaker. As a result, if the content of the user 10's speech at the time of an accident includes content that can lead to the elucidation of the cause of the accident, for example, the in-vehicle device 1 can record the in-vehicle voice 52 including the content of the user 10's speech without identifying the user 10. Therefore, the in-vehicle device 1 can record important in-vehicle voice 52 while reliably protecting the privacy of the user 10.

[0024] The controller 3 also stores pre-registered voice information 54 of the user 10, and compares the in-vehicle voice 52 with the voice information 54 of the user 10 to detect the voice of the user 10 from the in-vehicle voice 52. This allows the in-vehicle device 1 to accurately detect the voice of the user 10 from the in-vehicle voice 52.

[0025] Furthermore, the controller 3 associates a pre-registered facial image 55 of the user 10 with the voice information 54 of the user 10 and stores them in the storage 4. Then, the controller 3 compares the in-vehicle video 50 with the facial image 55 of the user 10 (for example, by face recognition processing), and when the controller 3 detects the user 10 from the in-vehicle video 50, it detects the voice of the user 10 from the in-vehicle audio 52. This allows the in-vehicle device 1 to more reliably detect the voice of the user 10 from the in-vehicle audio 52, even if, for example, there is another occupant with a similar voice quality.

[0026] Furthermore, the controller 3 may be configured to output in-vehicle voice 52 obtained by processing the voice of the user 10 when the voice output trigger is activated. In this case, the controller 3 starts processing the voice of the user 10 when the voice output trigger is activated. This allows the in-vehicle device 1 to avoid processing the voice of the user 10 unless the voice output trigger is activated, thereby reducing the processing load on the controller 3 and the power consumption required for processing the voice.

[0027] The controller 3 may also be configured to start processing the voice of the user 10 when the in-vehicle device 1 is started up. This allows the in-vehicle device 1 to process all recorded in-vehicle voices 52 so that the speaker of the voice of the user 10 cannot be identified by a third party, thereby reliably protecting the privacy of the user 10.

[0028] The controller 3 may also be configured to process the voice of the user 10 and record the in-vehicle voice 52 so that the voice of the user 10 is erased from the time the in-vehicle device 1 is started until the voice recording trigger is activated. The in-vehicle device 1 activates the voice recording trigger, for example, when the detection result of the sensor 22 indicating that an impact has been applied to the vehicle is input to the controller 3.

[0029] In this case, when the voice recording trigger is activated, the controller processes the voice of the user 10 and records the in-vehicle voice 52 so that the voice of the user 10 is converted into voice that does not identify the speaker of the user 10.

[0030] As a result, the vehicle-mounted device 1 can reduce the amount of storage 4 capacity used by erasing the user 10's voice from the in-vehicle voice 52 during a period when there is little possibility that the in-vehicle voice 52 will be required, for example, before a voice recording trigger is activated due to the occurrence of a vehicle accident.

[0031] Furthermore, during the period when a voice recording trigger is activated due to a vehicle accident and output of in-vehicle voice 52 is likely to be requested, the in-vehicle device 1 processes the voice of user 10 so that the speaker cannot be identified to a third party, and therefore, the contents of the conversation that are important for clarifying the cause of the accident can be output.

[0032] In this way, when an accident occurs, the in-vehicle device 1 records collision sounds and surrounding audio information 54 as important information, but does not record conversations inside the vehicle, so it is possible to satisfy the need to not record private information while preserving important information. Also, the in-vehicle device 1 can record in-vehicle audio 52 when necessary without identifying individuals.

[0033] [2. Processing performed by the in-vehicle controller] Next, a process executed by the controller 3 of the vehicle-mounted device 1 according to the embodiment will be described with reference to Fig. 2. Fig. 2 is a flowchart showing an example of a process executed by the controller 3 of the vehicle-mounted device 1 according to the embodiment.

[0034] While the controller 3 is running, it repeatedly executes the process shown in Fig. 2. Specifically, as shown in Fig. 2, when the vehicle-mounted device 1 is started, the controller 3 first determines whether or not user information 53 has been input (step S101).

[0035] At this time, the controller 3 determines whether or not voice information 54 of the user 10 has been input from the microphone 23 or the application of the user terminal 11. The controller 3 also determines whether or not a face image 55 of the user 10 has been input from the camera 20 that captures images of the interior of the vehicle or the application of the user terminal 11. When the controller 3 determines that user information 53 has not been input (No in step S101), the controller 3 proceeds to step S103.

[0036] When the controller 3 determines that the user information 53 has been input (Yes in step S101), the controller 3 registers the user information 53 in the storage 4 (step S102). For example, the controller 3 registers the user information 53 by storing voice information 54 and a facial image 55 of the user 10 in the storage 4.

[0037] Thereafter, the controller 3 records the vehicle exterior image 51 captured by the camera 21 and the vehicle interior sound 52 collected by the microphone 23 in the storage 4 (step S103). Next, the controller 3 determines whether or not there is registered user information 53 in the storage 4 (step S104). If the controller 3 determines that there is no registered user information 53 (step S104, No), it ends the current process.

[0038] If the controller 3 determines that registered user information 53 exists (step S104, Yes), it detects the voice of the user 10 corresponding to the pre-registered voice information 54 of the user 10 from the recorded in-vehicle voice 52 (step S105).

[0039] At this time, the controller 3, for example, compares the in-vehicle voice 52 with the voice information 54 of the user 10, and detects the voice of the user 10 from the in-vehicle voice 52. The controller 3 may also be configured to compare an in-vehicle video 50 captured by a camera 20 capturing an image of the interior of the vehicle with a facial image 55 of the user 10, and, when detecting the user 10 from the in-vehicle video 50, detect the voice of the user 10 from the in-vehicle voice 52.

[0040] Next, the controller 3 processes the detected voice of the user 10 (step S106). In this way, the controller 3 starts processing the voice of the user 10 when the vehicle-mounted device 1 is started up.

[0041] At this time, the controller 3 processes the voice of the user 10 so that the voice of the user 10 is erased. Alternatively, the controller 3 processes the voice of the user 10 so that the voice of the user 10 is converted into a voice from which the speaker of the voice of the user 10 cannot be identified.

[0042] Thereafter, the controller 3 records the in-vehicle voice 52 obtained by processing the voice of the user 10 in the storage 4 (step S107), and determines whether or not the voice output trigger has been activated (step S108).

[0043] The in-vehicle device 1 activates the audio output trigger, for example, when it receives a request to output recorded audio from an application on the user terminal 11. The in-vehicle device 1 may be configured to activate the audio output trigger, for example, when a predetermined output operation is performed on an operation unit (not shown).

[0044] If the controller 3 determines that the voice output trigger has not been activated (step S108, No), it ends the current process. If the controller 3 determines that the voice output trigger has been activated (step S108, Yes), it outputs the in-vehicle voice 52, which is the processed voice of the user 10 (step S109), and ends the current process.

[0045] At this time, the controller 3 outputs the vehicle exterior image 51 together with the vehicle interior sound 52. The controller 3 outputs the vehicle exterior image 51 and the vehicle interior sound 52 to, for example, a center device 12 provided in an information collection center via wireless communication. The controller 3 may be configured to output the vehicle exterior image 51 and the vehicle interior sound 52 to, for example, an external information storage medium.

[0046] [3. Modification of the process executed by the controller of the in-vehicle device] Next, a modified example of the process executed by the controller 3 of the vehicle-mounted device 1 according to the embodiment will be described with reference to Fig. 3. Fig. 3 is a flowchart showing a modified example of the process executed by the controller 3 of the vehicle-mounted device 1 according to the embodiment.

[0047] The controller 3 may be configured to execute the process shown in Fig. 3 instead of the process shown in Fig. 2. In this case, while the controller 3 is activated, it repeatedly executes the process shown in Fig. 3. As shown in Fig. 3, when the vehicle-mounted device 1 is activated, the controller 3 first determines whether or not user information 53 has been input (step S201).

[0048] At this time, the controller 3 determines whether or not voice information 54 of the user 10 has been input from the microphone 23 or the application of the user terminal 11. The controller 3 also determines whether or not a face image 55 of the user 10 has been input from the camera 20 that captures images of the interior of the vehicle or the application of the user terminal 11. When the controller 3 determines that user information 53 has not been input (No in step S201), the controller 3 proceeds to step S203.

[0049] When the controller 3 determines that the user information 53 has been input (Yes at step S201), the controller 3 registers the user information 53 in the storage 4 (step S202). For example, the controller 3 registers the user information 53 by storing voice information 54 and a facial image 55 of the user 10 in the storage 4.

[0050] Thereafter, the controller 3 records the vehicle exterior image 51 captured by the camera 21 and the vehicle interior sound 52 collected by the microphone 23 in the storage 4 (step S203). Next, the controller 3 determines whether or not there is registered user information 53 in the storage 4 (step S204). If the controller 3 determines that there is no registered user information 53 (step S204, No), it ends the current process.

[0051] If the controller 3 determines that registered user information 53 exists (step S204, Yes), it detects the voice of the user 10 corresponding to the pre-registered voice information 54 of the user 10 from the recorded in-vehicle voice 52 (step S205).

[0052] At this time, the controller 3, for example, compares the in-vehicle voice 52 with the voice information 54 of the user 10, and detects the voice of the user 10 from the in-vehicle voice 52. The controller 3 may also be configured to compare an in-vehicle video 50 captured by a camera 20 capturing an image of the interior of the vehicle with a facial image 55 of the user 10, and, when detecting the user 10 from the in-vehicle video 50, detect the voice of the user 10 from the in-vehicle voice 52.

[0053] Next, the controller 3 processes the voice of the user 10 so as to erase the voice of the user 10. Then, the controller 3 records the in-vehicle voice 52 from which the voice of the user 10 has been erased in the storage 4 (step S206).

[0054] Thereafter, the controller 3 determines whether or not a voice recording trigger has been activated (step S207). The vehicle-mounted device 1 activates the voice recording trigger when, for example, a detection result from the sensor 22 indicating that an impact has been applied to the vehicle is input to the controller 3.

[0055] If the controller 3 determines that the voice recording trigger has not been activated (step S207, No), the controller 3 proceeds to step S203. In this manner, the controller 3 processes the voice of the user 10 and records the in-vehicle voice 52 so that the voice of the user 10 is erased from the time the in-vehicle device 1 is started until the voice recording trigger is activated.

[0056] Furthermore, when the controller 3 determines that the voice recording trigger has been activated (step S207, Yes), it processes the voice of the user 10 so that the voice of the user 10 is converted into voice that does not identify the speaker of the voice of the user 10. Then, the controller 3 records the in-vehicle voice 52 into which the voice of the user 10 has been converted in the storage 4 (step S208). In this way, when the voice recording trigger has been activated, the controller 3 starts processing the voice of the user 10.

[0057] Thereafter, the controller 3 determines whether or not the audio output trigger has been activated (step S209). The vehicle-mounted device 1 activates the audio output trigger, for example, when it receives an output request for recorded audio from an application of the user terminal 11. The vehicle-mounted device 1 may be configured to activate the audio output trigger, for example, when a predetermined output operation is performed on an operation unit (not shown).

[0058] If the controller 3 determines that the voice output trigger has not been activated (step S209, No), the controller 3 ends this processing. If the controller 3 determines that the voice output trigger has been activated (step S209, Yes), the controller 3 outputs the in-vehicle voice 52 obtained by processing the voice of the user 10 (step S210), and ends this processing.

[0059] At this time, the controller 3 outputs the vehicle exterior image 51 together with the vehicle interior sound 52. The controller 3 outputs the vehicle exterior image 51 and the vehicle interior sound 52 to, for example, a center device 12 provided in an information collection center via wireless communication. The controller 3 may be configured to output the vehicle exterior image 51 and the vehicle interior sound 52 to, for example, an external information storage medium.

[0060] [4. Example of voice processing system configuration] Next, a configuration example of the voice processing system 100 according to the embodiment will be described with reference to Fig. 4. Fig. 4 is an explanatory diagram showing a configuration example of the voice processing system 100 according to the embodiment.

[0061] 4, the voice processing system 100 includes a center device 12 provided in an information collection center in addition to the vehicle-mounted device 1. The center device 12 includes a microcomputer having a CPU, ROM, RAM, etc., and various circuits. The center device 12 is capable of wireless communication with the vehicle-mounted device 1. The center device 12 is also capable of wireless communication with the user terminal 11.

[0062] The center device 12 includes a storage 13. The center device 12 stores user information 53 of pre-registered users 10 in the storage 13. The users 10 can use a predetermined application installed on the user terminal 11 to record their own voice and capture an image 55 of their own face, and transmit the image from the user terminal 11 to the center device 12.

[0063] Furthermore, the user 10 can use the app to transmit vehicle information 56 of the vehicle they are using from the user terminal 11 to the center device 12. The vehicle information 56 includes the vehicle's license plate number, chassis number, and a preset ID for the vehicle.

[0064] The center device 12 stores and registers the voice information 54, face image 55, and vehicle information 56 of the user 10 received from the user terminal 11 in the storage 13. The center device 12 transmits user information 53 including the voice information 54 and face image 55 of the user 10 registered in the storage 13 to the vehicle-mounted device 1.

[0065] The vehicle-mounted device 1 records the in-vehicle voice 52 and detects, from the recorded in-vehicle voice 52, the voice of the user 10 corresponding to the voice information 54 of the user 10 received from the center device 12. Then, the vehicle-mounted device 1 processes the detected voice of the user 10, similar to the vehicle-mounted device 1 shown in FIG.

[0066] According to the voice processing system 100, the vehicle-mounted device 1 processes the recorded voice of the user 10 so that the user 10 cannot be identified from the voice, thereby protecting the privacy of the user 10 and recording important in-vehicle voice 52.

[0067] Furthermore, when the center device 12 receives occupant information from the vehicle-mounted device 1, it transmits voice information 54 of the user 10 corresponding to the occupant information to the vehicle-mounted device 1. The vehicle-mounted device 1 that receives the voice information 54 processes the voice of the user 10 detected from the recorded in-vehicle voice 52, similar to the vehicle-mounted device 1 shown in FIG.

[0068] This allows the user 10 to have his / her own voice information 54 sent from the center device 12 to the onboard device 1 of the vehicle he / she is using, even if it is the first time he / she is using the vehicle, such as a rental car or a car sharing vehicle, so that the speaker of his / her own voice stored in the onboard device 1 cannot be identified.

[0069] [5. Processing performed by the controller of the central device] Next, a process executed by the center device 12 according to the embodiment will be described with reference to Fig. 5. Fig. 5 is a flowchart showing an example of a process executed by the center device 12 according to the embodiment.

[0070] While the center device 12 is powered on, it repeatedly executes the process shown in Fig. 5. Specifically, when the center device 12 is powered on, it first determines whether or not user information 53 has been input (step S301).

[0071] At this time, the center device 12 determines whether or not voice information 54 of the user 10 has been input from the application of the in-vehicle device 1 or the user terminal 11. In addition, the controller 3 determines whether or not a face image 55 of the user 10 has been input from the application of the in-vehicle device 1 or the user terminal 11.

[0072] Furthermore, the center device 12 determines whether or not vehicle information 56 on which the onboard device 1 is installed has been input from the application of the onboard device 1 or the user terminal 11. The vehicle information 56 includes the license plate number, the vehicle identification number, and a preset ID of the vehicle.

[0073] If the center device 12 determines that the user information 53 has not been input (step S301, No), the center device 12 proceeds to step S305. If the center device 12 determines that the user information 53 has been input (step S301, Yes), the center device 12 stores and registers the input user information 53 in the storage 13 (step S302).

[0074] Thereafter, the center device 12 determines whether the user information 53 is input from an application of the user terminal 11 (step S303). If the center device 12 determines that the user information 53 is not input from an application (step S303, No), the center device 12 proceeds to step S305.

[0075] Furthermore, if the center device 12 determines that the user information 53 is input from the app (step S303, Yes), it transmits the user 10's voice information 54 to the user 10's vehicle-mounted device 1 (step S304), and terminates this processing.

[0076] In step S305, the center device 12 determines whether or not occupant information has been received from the vehicle-mounted device 1. The occupant information is, for example, voice information 54 of the user of the vehicle in which the vehicle-mounted device 1 is installed, a facial image 55 of the user, or vehicle information 56.

[0077] If the center device 12 determines that it has not received the vehicle information 56 (step S305, No), it ends the current process. On the other hand, if the center device 12 determines that it has received the vehicle information 56 (step S305, Yes), it transmits the voice information 54 of the user 10 corresponding to the occupant information to the vehicle-mounted device 1 (step S306), and ends the current process.

[0078] The controller 3 of the vehicle-mounted device 1 in the voice processing system 100 executes the same process as that shown in Fig. 2 or 3. However, in this case, the controller 3 of the vehicle-mounted device 1 determines whether or not voice information 54 of the user 10 has been input from the microphone 23, the application of the user terminal 11, or the center device 12, in step S101 shown in Fig. 2 or step S201 shown in Fig. 3. The controller 3 of the vehicle-mounted device 1 determines whether or not a face image 55 of the user 10 has been input from the camera 20 capturing an image of the interior of the vehicle, the application of the user terminal 11, or the center device 12.
