The base unit 10 detects, for example, sensor detection information from various sensors 40 wirelessly connected by DECT (for example, information indicating that an elderly person PR has been detected alone or information indicating that an abnormality (see below) has been detected in an elderly person living alone). Is transferred, the sensor detection information is transmitted to the smartphone 50 via the wireless router 60.

  The base unit 10 includes a DECT protocol control unit 108 and a DECT wireless I / F unit 107, and uses the DECT wireless communication method to provide a cordless slave unit 20, a monitoring camera 30, and various sensors 40. Wireless connection and wireless communication.

  Master device 10 also includes an audio bus 117, an audio input / output control unit 104, a speaker 129, and a microphone 128, and inputs / outputs audio to / from the outside. For example, if the parent device 10 receives the voice data of the son SN's call voice transmitted from the smartphone 50 possessed by the son SN, the parent device 10 outputs the voice data from the speaker 129 as a voice. Further, when the solitary elderly person PR speaks to the microphone 128, the base unit 10 transmits the voice data of the voice collected by the microphone 128 to the smartphone 50 via the wireless router 60. Thereby, for example, the smartphone 50 held by the son SN and the parent device 10 near the solitary elderly person PR can make a voice call via the wireless router 60 using the wireless LAN.

  Master unit 10 has fixed telephone line I / F unit 101 and can communicate with and communicate with an external fixed telephone 800 connected to fixed telephone network 85. As described above, the base unit 10 performs various processes of voice data during a call so that a call can be made between the external fixed telephone 800 connected to the fixed telephone network 85 and the cordless handset 20. You may control. In this case, for example, the smartphone 50 gripped by the son SN and the cordless handset 20 gripped by the solitary elderly person PR can make a voice call via the base unit 10.

  Moreover, the main | base station 10 has the subunit | mobile_unit / portable terminal charge part 126, and can charge the cordless subunit | mobile_unit 20 or the smart phone 50 inserted in the insertion port (not shown).

As a result, when the base unit 10 receives the RFID signal from the RFID tag when the RFID of the RFID tag is registered in advance in association with the elderly person PR, the base unit 10 performs wireless communication between the base unit 10 and the RFID tag. It is easy to recognize that there is an elderly person who lives alone within the possible communication range. The base unit 10 may transmit the recognition result information indicating the recognition result to the smartphone 50 via the wireless router 60 or may transmit the recognition result information to the monitoring camera 30 via DECT.

  FIG. 4 is a block diagram illustrating in detail an example of the internal configuration of the monitoring camera 30 of the monitoring system 5. The monitoring camera 30 includes a control unit 309, a storage unit 303, and an operation unit 305. The monitoring camera 30 is installed to watch the elderly living alone PR, performs an operation related to imaging in the elderly living alone, which is a monitoring target area, and accepts an input operation of a user (for example, the elderly living alone PR).

  Whether the control unit 309 has been subjected to a blurring process or an optical filter process on normal captured image data (first image data) and normal captured image data (first image data). The image output of the captured image data (second image data) is controlled. In other words, the control unit 309 controls switching between the two image output modes, specifically, the first output mode for outputting the first image data described above and the second image data described above. The image output mode control signal for switching to the second output mode is generated and output to the imaging unit 312. Details of the operation of the control unit 309 for switching the image output mode will be described in detail with reference to FIGS. 7, 8, and 10 to 13.

  The control unit 309 includes a face recognition unit 309A and a timer 309B.

  The face recognition unit 309A serving as a recognition unit performs face recognition processing based on normal captured image data output from the imaging unit 312 and extracts information about the face (for example, facial feature point information). The recognition processing result is compared with information (for example, facial feature point information) related to the face of the solitary elderly person PR registered in advance in the storage unit 303 to determine whether or not the face of the solitary elderly person PR has been recognized. The control unit 309 switches an image output mode, which will be described later, to the first output mode or the second output mode or continues the first output mode or the second output mode according to the determination result of the face recognition unit 309A.

  The timer 309B has a timekeeping function. For example, when a motion of a moving body (for example, an aged person who lives alone) is detected by an infrared sensor unit 313B that constitutes a human sensor, the time from the detection. Timed as a motion detection waiting timer for a certain period. The moving object detection waiting timer corresponds to a polling (inquiry) cycle from the control unit 309, for example.

  The monitoring camera 30 includes a DECT protocol control unit 317 and a DECT wireless I / F unit 318, and is wirelessly connected to the base unit 10 and various sensors 40 using the DECT wireless communication method. Wireless communication.

  The monitoring camera 30AA (see FIG. 2) includes a wireless LAN control unit 321 and a wireless LAN communication I / F unit 322 as wireless communication units, and via a wireless router 60 using a wireless LAN. It is also possible to transmit / receive image data and audio data to / from the base unit 10, the smartphone 50, and the like. 4 shows a wireless LAN control unit 321 and a wireless LAN communication I / F unit 322 as the configuration of the monitoring camera 30. In the monitoring cameras 30A, 30B, and 30C shown in FIG. The wireless LAN control unit 321 and the wireless LAN communication I / F unit 322 may be omitted or may be provided.

  The monitoring camera 30 includes an audio bus 307, an audio input / output control unit 304, a speaker 329, and a microphone 328, and inputs / outputs audio to / from the outside (for example, the cordless handset 20 and the smartphone 50). To make a call. For example, if the voice data of the voice of the son SN transmitted from the smartphone 50 possessed by the son SN is received by the watch monitoring camera 30 via the wireless router 60 and the parent device 10, the watch monitoring camera 30 The audio data is output as audio from the speaker 329. In addition, when the solitary elderly person PR speaks to the microphone 328, the monitoring camera 30 transmits the audio data of the sound collected by the microphone 328 to the smartphone 50 via the parent device 10 and the wireless router 60. (See FIG. 1), or directly to the smartphone 50 via the wireless router 60 without going through the parent device 10 (see FIG. 2). Thereby, for example, the smart phone 50 held by the son SN and the watching surveillance cameras 30 and 30AA near the solitary elderly person PR can perform a voice call via the wireless router 60 using a wireless LAN.

  The monitoring camera 30 includes an imaging unit 312, an image memory control unit 316, and an image memory 315, and stores image data output from the imaging unit 312 in the image memory 315. Here, the configuration of the imaging unit 312 as an image output unit will be described. The imaging unit 312 includes a lens LNS, a filter unit F1, an image sensor IS, and an image processing unit DP.

  The lens LNS receives reflected light (visible light or infrared light) from the monitoring target region and forms an image of the incident light on the image sensor IS through the filter unit F1 or without using the filter unit F1. The image is formed on the image sensor IS.

  The filter unit F1 as an optical filter unit is configured using a so-called optical filter (for example, frosted glass), and an image sensor is operated by an actuator (not shown) according to an image output mode control signal (see later) from the control unit 309. It is arranged so as to cover the IS, or arranged so as not to cover the image sensor IS. The filter unit F1 performs an optical filter process for diffusing (diverging) the light incident on the lens LNS. As a result, it is possible to obtain the data of the captured image obtained by applying the processing to the normal captured image data. FIG. 4 shows an example in which the filter unit F1 is arranged so as to cover the image sensor IS.

  The image sensor IS is an image sensor (for example, an image sensor such as a charge coupled device (CCD) or a complementary metal oxide semiconductor (CMOS)). The image sensor IS converts an optical image of the monitoring target region imaged via the filter unit F1 into an electrical signal, or converts an optical image of the monitoring target region imaged without passing through the filter unit F1 into an electrical signal. To do.

  The image processing unit DP performs predetermined image processing using the electrical signal generated by the image sensor IS, and generates image data in a predetermined format (for example, H.264 format) such as RGB or YUV. In response to an image output mode control signal from the control unit 309, the image processing unit DP performs digital signal processing (an image processing) on the image data in the predetermined format (that is, the entire image frame) in the second output mode. For example, the data of the captured image subjected to the mosaic image processing (such as mosaic processing) is generated and output to the control unit 309 and the image memory control unit 316. Further, the image processing unit DP performs digital signal processing (see above) on the image data in the predetermined format (that is, the entire image frame) in the first output mode according to the image output mode control signal from the control unit 309. ) Is generated and output to the control unit 309 and the image memory control unit 316.

  FIG. 9A is an example of a normal captured image PC1. FIG. 9B is an example of the blurring captured image PC2 based on the optical filter processing by the filter unit F1 and the digital signal processing by the image processing unit DP. FIG. 9C is an example of a blurry captured image PC3 based on the optical filter processing by the filter unit F1. FIG. 9D is an example of a blurry captured image PC4 based on digital signal processing by the image processing unit DP.

  When a normal captured image PC1 is generated by the monitoring camera 30, for example, the smartphone 50 that has received the data of the normal captured image PC1 from the monitoring camera 30 accurately tells the son SN the status of the aged elderly person who is the subject. Can be grasped.

  On the other hand, if any one of the captured images PC2, PC3, and PC4 is generated by the monitoring camera 30, for example, the data of any of the captured images PC2, PC3, and PC4 from the monitoring camera 30 is used. The received smartphone 50 can cause the son SN to grasp the situation of the solitary elderly person PR who is the subject, and can protect the privacy of the solitary elderly person PR accurately.

  The faintly picked-up image PC2 does not show the expression of the solitary elderly person PR and does not know the fine movement, but it is possible to observe a rough movement such as getting up.

  Although the detailed expression of the solitary elderly person PR is not known from the faint captured image PC3, the movement can be observed.

  Although the detailed image of the solitary elderly person PR is not known by the faint captured image PC4, the movement can be observed.

  The monitoring camera 30 includes an infrared irradiation unit 313A and an infrared sensor unit 313B, which are PIR (Passive Infra Red) sensors, as human sensors. The infrared irradiation unit 313A irradiates infrared rays (infrared light) toward the monitoring target region. The infrared sensor unit 313B detects a change in reception of infrared light (infrared light) reflected by a person (for example, a single person living alone PR) by the infrared light (infrared light) emitted from the infrared irradiation unit 313A. It detects that it is moving, or detects that the elderly single person PR does not move. The infrared sensor unit 313B outputs to the control unit 309 sensor detection information indicating that the movement of the solitary elderly person PR is detected or sensor detection information indicating that the movement of the solitary elderly person PR is not detected.

  The monitoring camera 30 includes a temperature sensor unit 313C that detects an abnormal increase in the temperature of a monitoring target area (for example, a room in a living alone living room) as an abnormal sensor. For example, when the temperature sensor unit 313C detects a temperature exceeding a predetermined temperature, the temperature sensor unit 313C outputs sensor detection information indicating that an abnormality of the monitoring target region has been detected to the control unit 309.

  The monitoring camera 30 includes a power supply unit 314 configured by, for example, a commercial AC power supply or a DC power supply.

  The monitoring camera 30 includes an RFID receiving unit 331. For example, the RFID receiving unit 331 receives an RFID signal transmitted from an RFID tag (not shown) held or attached by the solitary elderly person PR. As a result, when the monitoring camera 30 receives the RFID signal from the RFID tag when the RFID of the RFID tag and the elderly single person PR are registered in advance in association with each other, the monitoring camera 30 wirelessly connects the monitoring camera 30 and the RFID tag. It is possible to easily recognize that there is an elderly person who lives alone within a communicable range. The monitoring camera 30 may transmit recognition result information indicating the recognition result to the smartphone 50 via the wireless router 60 or to the parent device 10 via DECT.

Perform wireless communication. When the sensor 40 detects any event described above, the sensor 40 transmits sensor detection information to the parent device 10 or the monitoring camera 30 via DECT.

  The sensor unit 453 detects an event to be detected and differs depending on the type of the sensor 40. For example, in the case of the human sensor 40A, the sensor unit 453 is a PIR sensor that detects the presence or absence of the movement of the solitary elderly person PR based on the change in the received infrared ray, and the infrared irradiation unit 313A and the infrared sensor unit 313B illustrated in FIG. The configuration is equivalent. In the case of the CO sensor 40B, the sensor unit 453 detects whether or not CO (carbon monoxide) in the monitoring target region has reached an amount (concentration) equal to or greater than a predetermined value. In the case of the smoke sensor 40C, the sensor unit 453 is a light emitting unit and a light receiving unit that sense smoke when the emitted light is blocked by the smoke. In the case of the window sensor 40D that detects opening / closing of a window or the like, the sensor unit 453 may be a reed switch that is turned on / off by opening / closing, or may be a vibration sensor that detects vibration generated when the window is opened / closed.

  The rechargeable battery 450 is a rechargeable battery and supplies necessary power to each part of the sensor 40.

  FIG. 6 is a block diagram showing in detail an example of the internal configuration of the smartphone 50 of the watch monitoring system 5. As shown in FIG. 1 and FIG. 2, the smartphone 50 may be used by a user (for example, an elderly person who lives alone) inside the elderly living alone, or used by a user (for example, a son SN) outside the elderly living alone. Sometimes it is done. The smartphone 50 includes a control unit 506, a storage unit 504, and a display / operation unit 503. The display / operation unit 503 as a display is configured using, for example, a touch panel. The smartphone 50 receives various input operations from the user, and displays, for example, the first image data or the second image data generated by the watching monitoring camera 30 on the display / operation unit 503.

  The control unit 506 includes a monitoring function control unit 514 that can set various types of setting information of the watching monitoring camera 30. The display / operation unit 503 is a display input unit (for example, a touch panel) in which the display unit and the operation unit are integrated, and displays various kinds of information such as the first image data, the second image data, and icons described above on the screen. Or accepting a tap operation (or touch operation) on the screen by the user.

  The smartphone 50 includes an audio bus 515, an audio input / output control unit 505, a speaker 513, and a microphone 512, and inputs / outputs audio to / from the outside. For example, if the voice data of the call voice of the solitary elderly person PR transmitted from the watching surveillance camera 30 arranged near the solitary elderly person PR is received by the smartphone 50 via the parent device 10, the smartphone 50 Data is output as audio from the speaker 513. Further, when the son SN speaks to the microphone 512, the smartphone 50 transmits the voice data of the voice collected by the microphone 512 to the parent device 10 via the wireless router 60. This audio data is transmitted to the monitoring camera 30 via the parent device 10 using DECT. Thus, for example, the parent device 10 near the solitary elderly PR and the smartphone 50 held by the son SN can directly make a voice call via the parent device 10 using DECT and the wireless router 60 using the wireless LAN. It can be carried out.

  In addition, the smartphone 50 includes a wireless LAN control unit 507 and a wireless LAN communication I / F unit 508, and image data and the parent device 10, the monitoring camera 30, and the like via a wireless router 60 using a wireless LAN. And transmit / receive audio data.

  The smartphone 50 performs wireless communication with the parent device 10 via the wireless router 60 using a wireless LAN. For example, the sensor detection information (from the sensor 40 wirelessly connected to the parent device 10 by DECT) ( For example, when the information indicating that the elderly person PR alone has been detected), the sensor detection information transferred from the parent device 10 can be received. In addition, when a user operation is input to the display / operation unit 503, the smartphone 50 can transmit information corresponding to the user operation to the parent device 10 via the wireless router 60.

  In addition, when there is an input operation of a user of the smartphone 50 (for example, son SN), the smartphone 50 is based on the input operation (for example, a new creation or change input operation of setting information that defines the operation of various sensors 40). Data or information (for example, setting information of various sensors 40) is transmitted to the parent device 10 via the wireless router 60. The base unit 10 can store the setting information of the various sensors 40 transmitted from the smartphone 50 in the storage unit 103 and register the setting information of the various sensors 40 in the corresponding sensor 40. Thereby, the smartphone 50 can freely set and change the setting information of various sensors 40 by the user's operation.

  Further, the smartphone 50 includes a USB communication I / F unit 511, and transmits / receives data to / from a device or a memory having a USB standard interface.

  Moreover, the smart phone 50 supplies electric power required for the operation | movement to each part of the smart phone 50 with the secondary battery 550. FIG.

  Next, a first example in which the image output mode is switched according to the presence or absence of moving object detection in the first embodiment will be described with reference to FIG. FIG. 7 is a sequence diagram illustrating in detail a first example of an operation procedure for switching an image output mode in accordance with the presence or absence of moving object detection in the first embodiment.

  In FIG. 7, in order to explain the operation of the monitoring camera 30 in detail, the control unit 309 and the infrared sensor unit 313B are shown separately. For example, the infrared sensor unit 313B in the monitoring camera 30 detects the aged person PR alone. An example will be described in which the control unit 309 switches or continues the image output mode according to time and non-detection time. In addition, as a premise of the description of FIG. 7, it is assumed that the smartphone 50 is being held and used by the son SN of the solitary elderly person PR.

  In FIG. 7, the smartphone 50 and the parent device 10 are wirelessly connected to each other via a wireless router 60 using a WLAN (that is, a wireless LAN) (S1). The master unit 10 and the monitoring camera 30 are wirelessly connected to each other via DECT (S2). The control unit 309 drives the infrared irradiation unit 313A to start infrared irradiation, and drives the infrared sensor unit 313B to start infrared reception (S3). Thereby, the detection of the existence of the solitary elderly person PR or the solitary elderly person PR by the infrared sensor unit 313B is started.

  It is assumed that sensor detection information indicating no moving object detection (that is, no movement of the solitary elderly person PR is not detected) is interrupted and input to the control unit 309 by the infrared sensor unit 313B (S4). For example, there may be a state where there is no single elderly person PR in a room which is a monitoring target area. After step S4, the infrared sensor unit 313B outputs an interrupt signal including sensor detection information to the control unit 309, for example, every 5 seconds (see S9, S12, S16, S17, S18, and S19). The output interval of the interrupt signal is not limited to 5 seconds. For example, the monitoring camera 30 may change and register the information on the output interval of the interrupt signal in accordance with the setting information change operation by the smartphone 50.

  The control unit 309 sets the image output mode to the first output mode capable of normal image processing in response to the input of the sensor detection information in step S4 (S5). Therefore, when the image output mode of the monitoring camera 30 is the first output mode immediately before step S5, the control unit 309 continues the first output mode in step S5. On the other hand, when the image output mode of the monitoring camera 30 is the second output mode immediately before step S5, the control unit 309 switches from the second output mode to the first output mode in step S5. As a result, the monitoring camera 30 can generate normal captured image data (first image data, see FIG. 9A) in the first output mode.

  Here, when there is an input operation of the monitor instruction of the son SN (S6), the smartphone 50 sends the operation information of the monitor instruction (for example, an instruction to acquire and display the image data of the monitoring camera 30) via the wireless router 60. To the base unit 10 (S7). The base unit 10 receives the operation information of the monitor instruction transmitted from the smartphone 50, and transmits the operation information to the monitoring camera 30 via DECT (S8). The control unit 309 acquires the operation information transmitted in step S8. After this acquisition, it is assumed that an interrupt signal output from the infrared sensor unit 313B is input to the control unit 309 (S9). The content of the interrupt signal is sensor detection information without moving object detection. That is, it is information indicating that the movement of the solitary elderly person PR is not detected.

  Since the control unit 309 has recognized that the movement of the solitary elderly person PR is not detected at the time of step S9, the image output mode is continued to the first output mode. Further, the control unit 309 converts the moving image data based on the first image data (that is, the data of the normal captured image PC1) obtained from the imaging unit 312 and the audio data of the audio collected by the microphone 328, to DECT. To the base unit 10 (S10). The base unit 10 receives the moving image data and audio data transmitted from the monitoring camera 30 and transmits the moving image data and audio data to the smartphone 50 via the wireless router 60 (S11). The smartphone 50 displays and reproduces the moving image data transmitted from the parent device 10 on the display / operation unit 503, and further outputs the sound data transmitted from the parent device 10 through the speaker 513.

  Here, it is assumed that the interrupt signal output from the infrared sensor unit 313B is input to the control unit 309 (S12). The content of the interrupt signal is sensor detection information with motion detection. That is, the movement of the solitary elderly person PR is detected when the solitary elderly person PR enters the monitoring target area (for example, a room). Based on this interrupt signal, the control unit 309 switches the image output mode from the first output mode to the second output mode, and sets the image output mode to the second output mode (S13). As a result, the monitoring camera 30 generates the data of the captured image when the movement of the solitary elderly person PR is detected. Therefore, for example, the privacy of the solitary elderly person PR who does not want to be monitored is protected. It can be protected accurately.

  Furthermore, the control unit 309 transmits the sensor detection information included in the interrupt signal acquired in step S12 to the parent device 10 via DECT (S14). Master device 10 receives the sensor detection information and transmits the sensor detection information to smartphone 50 via wireless router 60 (S15). Further, the control unit 309 switches the second image data obtained from the imaging unit 312 (that is, any one of the fraudulent captured images PC2, PC3, PC4) when the image output mode is switched to the second output mode. Data) and audio data of the voice of the solitary elderly person PR collected by the microphone 328 are transmitted to the parent device 10 via DECT (S14A). Master device 10 receives the moving image data and the audio data transmitted from watching monitoring camera 30, and transmits the moving image data and the audio data to smartphone 50 via wireless router 60 (S15A). The smartphone 50 displays and reproduces the moving image data transmitted from the parent device 10 on the display / operation unit 503, and further outputs the sound data transmitted from the parent device 10 through the speaker 513. Accordingly, the son SN browses the moving image data based on the image data that has been subjected to the fraudulent processing on the display / operation unit 503 of the smartphone 50, thereby protecting the privacy at the time of imaging of the solitary elderly person PR (his own parent). It is possible to roughly grasp the state of the elderly living alone. The processes in steps S14A and S15A are continued in the same manner for each predetermined period until the image output mode is switched in step S22 described later. Note that the processes of steps S14 and S15 may be performed before the process of step S13.

  Here, it is assumed that the interrupt signal output from the infrared sensor unit 313B is input to the control unit 309 (S16). The content of the interrupt signal is sensor detection information with motion detection. That is, it is information that the movement of the solitary elderly person PR is detected.

  Assume that an interrupt signal output from the infrared sensor unit 313B is input to the control unit 309 after 5 seconds, for example, from the time of step S16 (S17). The content of the interrupt signal is sensor detection information with motion detection. That is, it is information that the movement of the solitary elderly person PR is detected.

  Assume that an interrupt signal output from the infrared sensor unit 313B is input to the control unit 309 after 5 seconds, for example, from the time of step S17 (S18). The content of the interrupt signal is sensor detection information without moving object detection. That is, it is information indicating that the movement of the solitary elderly person PR is not detected.

  Assume that an interrupt signal output from the infrared sensor unit 313B is input to the control unit 309 after 5 seconds, for example, from the time of step S18 (S19). The content of the interrupt signal is sensor detection information with motion detection. That is, it is information indicating that the movement of the solitary elderly person PR is not detected.

  When the control unit 309 continuously receives an interrupt signal including sensor detection information without moving object detection a plurality of times (for example, two times or three times), the control unit 309 transmits the sensor detection information to the parent device 10 via DECT ( S20). The base unit 10 receives the sensor detection information and transmits the sensor detection information to the smartphone 50 via the wireless router 60 (S21).

  Further, the control unit 309 determines that the solitary elderly person PR is not moving (for example, the solitary elderly person PR has fallen within the monitoring target area), and switches the image output mode from the second output mode to the first output mode (S22). The image output mode is set to the first output mode. In addition, the control unit 309 switches the moving image data based on the first image data (that is, the data of the normal captured image PC1) obtained from the imaging unit 312 and the microphone 328 when the image output mode is switched to the first output mode. The voice data of the voice picked up by is transmitted to the base unit 10 via DECT (S20A). Master device 10 receives the moving image data and audio data transmitted from watching monitoring camera 30, and transmits the moving image data and audio data to smartphone 50 via wireless router 60 (S21A). The smartphone 50 displays and reproduces the moving image data transmitted from the parent device 10 on the display / operation unit 503, and further outputs the sound data transmitted from the parent device 10 through the speaker 513. Thereby, the son SN who uses the smartphone 50 confirms the clear moving image data and audio data that have not been subjected to the fraud process, for example, the monitoring target region where the elderly single person PR has fallen within the monitoring target region. It is possible to quickly grasp the exact situation in the system and take appropriate measures thereafter.

  Next, a second example of switching the image output mode according to the presence or absence of moving object detection in the first embodiment will be described with reference to FIG. FIG. 8 is a sequence diagram illustrating in detail a second example of the operation procedure for switching the image output mode in accordance with the presence or absence of moving object detection in the first embodiment. In FIG. 8, the same operations as those in FIG. 7 are given the same step numbers, and the description is simplified or omitted, and different contents will be described. Further, as a premise of the description of FIG. 8, the monitoring camera 30 detects the presence or absence of movement of a moving object (for example, a single elderly person PR) based on a change (difference) between frames of image data obtained from the imaging unit 312. To do.

  In FIG. 8, after step S <b> 2, the control unit 309 of the monitoring camera 30 moves the moving object (for example, the elderly living alone) based on the change (difference) between the frames of the image data obtained from the imaging unit 312. Detect that there was. In this case, the control unit 309 switches the image output mode from the first output mode to the second output mode, or continues the image output mode in the second output mode (S31). That is, the control unit 309 sets the image output mode to the second output mode. As a result, the monitoring camera 30 generates the data of the captured image when the movement of the solitary elderly person PR is detected. Therefore, for example, the privacy of the solitary elderly person PR who does not want to be monitored is protected. It can be protected accurately.

  In addition, the timer 309B of the control unit 309 is a predetermined period (for example, 3 minutes or less) as a first moving object detection waiting timer from the time when it is determined that the movement of the moving object (for example, an elderly person living alone) has been detected. The time is measured until the same applies) (S32). After a predetermined time of the moving object detection waiting timer elapses, the control unit 309 determines a moving object (for example, an elderly person who lives alone) based on a change (difference) between frames of image data (second image data) obtained from the imaging unit 312. ) Is detected. When the control unit 309 does not determine that the movement of the solitary elderly person PR has been detected, the control unit 309 switches the image output mode from the second output mode to the first output mode (S33). That is, the control unit 309 sets the image output mode to the first output mode. Thereby, the monitoring camera 30 does not detect the movement of the solitary elderly person PR, and therefore can acquire the first image data (normal captured image data) that enables accurate grasp of the situation inside the solitary elderly person's house.

  After the timer 309B finishes timing of the first moving object detection waiting timer, the control unit 309 determines the moving object (second difference) based on the change (difference) between frames of the image data (second image data) obtained from the imaging unit 312. For example, it is assumed that the movement of the solitary elderly person PR) is detected (S34). The control unit 309 counts time as a second moving object detection waiting timer from the time when it is determined that the movement of the moving object (for example, an elderly person living alone) has been detected (S35). Further, the control unit 309 switches the image output mode from the first output mode to the second output mode (S36). That is, the control unit 309 sets the image output mode to the second output mode. As a result, the monitoring camera 30 generates the data of the captured image when the movement of the solitary elderly person PR is detected. Therefore, for example, the privacy of the solitary elderly person PR who does not want to be monitored is protected. It can be protected accurately.

  Here, it is assumed that there is a monitor instruction input operation on the smartphone 50 of the son SN during the operation of the second motion detection waiting timer by the timer 309B (S6). In this case, the control unit 309 acquires the operation information (see FIG. 7) transmitted in step S8 of FIG. At this time, since the image output mode is set to the second output mode, the control unit 309 causes the second image data obtained from the imaging unit 312 (that is, any one of the fraudulent captured images PC2, PC3, and PC4). ) And the voice data of the voice of the old living alone PR collected by the microphone 328 are transmitted to the base unit 10 via DECT (S37). The base unit 10 receives the moving image data and audio data transmitted from the monitoring camera 30 and transmits the moving image data and audio data to the smartphone 50 via the wireless router 60 (S38). The smartphone 50 displays and reproduces the moving image data transmitted from the parent device 10 on the display / operation unit 503, and further outputs the sound data transmitted from the parent device 10 through the speaker 513. Accordingly, the son SN browses the moving image data based on the image data that has been subjected to the fraudulent processing on the display / operation unit 503 of the smartphone 50, thereby protecting the privacy at the time of imaging of the solitary elderly person PR (his own parent). It is possible to roughly grasp the state of the elderly living alone.

  After the timer 309B finishes counting the second moving object detection waiting timer, the control unit 309 uses the moving object (second image data) based on the change (difference) between the frames of the image data (second image data) obtained from the imaging unit 312. For example, it is assumed that the movement of the solitary elderly person PR) is detected (S39). The control unit 309 measures time until a predetermined time period elapses as a third moving object detection waiting timer from the time when it is determined that the movement of the moving object (for example, the solitary elderly person PR) has been detected (S40).

  However, the control unit 309, based on the change (difference) between frames of the image data (second image data) obtained from the imaging unit 312 after the timer 309B finishes counting the third motion detection waiting timer. It is assumed that the movement of a moving object (for example, a single elderly person PR) is not detected. In this case, for example, it is conceivable that the solitary elderly person PR has fallen in a room which is the monitoring target area. The control unit 309 switches the image output mode from the second output mode to the first output mode (S41). That is, the control unit 309 sets the image output mode to the first output mode. Thereby, the monitoring camera 30 does not detect the movement of the solitary elderly person PR, and therefore can acquire the first image data (normal captured image data) that enables accurate grasp of the situation inside the solitary elderly person's house.

  Further, the control unit 309 converts the moving image data based on the first image data (that is, the data of the normal captured image PC1) obtained from the imaging unit 312 and the audio data of the audio collected by the microphone 328, to DECT. To the base unit 10 (S42). The base unit 10 receives the moving image data and audio data transmitted from the monitoring camera 30 and transmits the moving image data and audio data to the smartphone 50 via the wireless router 60 (S43). The smartphone 50 displays and reproduces the moving image data transmitted from the parent device 10 on the display / operation unit 503, and further outputs the sound data transmitted from the parent device 10 through the speaker 513. Thereby, the son SN who uses the smartphone 50 confirms the clear moving image data and audio data that have not been subjected to the fraud process, for example, the monitoring target region where the elderly single person PR has fallen within the monitoring target region. It is possible to quickly grasp the exact situation in the system and take appropriate measures thereafter.

  As described above, in the monitoring system 5 according to the first embodiment, the monitoring camera 30 performs the first output mode for outputting the first image data obtained by imaging the monitoring target area and the first image data through the processing. It is possible to switch between the second output mode for outputting the second image data. The monitoring camera 30 outputs the first image data in the first output mode, and outputs the second image data in the second output mode. The monitoring camera 30 detects the movement of a person (for example, a single elderly person PR) in the monitoring target area. The monitoring camera 30 continues the second output mode when the movement of the solitary elderly person PR is detected during the second output mode. Moreover, the monitoring camera 30 switches from the second output mode to the first output mode when the movement of the solitary elderly person PR is not detected for a predetermined time during the second output mode.

  As a result, the monitoring camera 30 protects the privacy at the time of imaging of the single elderly person PR to be watched when watching the resident of the elderly living alone (that is, the single person elderly person PR). For example, it is possible to achieve both the grasp of the accurate situation of the single elderly person PR when watching over his son SN). That is, the monitoring camera 30 can suppress the deterioration of service quality when watching a single elderly person PR who is estimated to increase in the future with the progress of an aging society.

  Moreover, the monitoring camera 30 will switch from 1st output mode to 2nd output mode, if the movement of the single person elderly person PR is detected by itself during 1st output mode. As a result, the monitoring camera 30 generates the data of the captured image when the movement of the solitary elderly person PR is detected. Therefore, for example, the privacy of the solitary elderly person PR who does not want to be monitored is protected. It can be protected accurately.

  Moreover, the monitoring camera 30 switches from the second output mode to the first output mode when it detects the movement of the solitary elderly person PR after a predetermined time has elapsed from the time when the second output mode is switched to the first output mode. As a result, the monitoring camera 30 has the image output mode set to the first when the single elderly person PR moves a little when the single elderly person PR falls to the floor or the like and the image output mode is switched to the first output mode. It is possible to prevent the switching to the two-output mode, and it is possible to acquire the first image data that makes it possible to grasp the exact situation of the solitary elderly person PR.

  In addition, when the monitoring camera 30 detects an abnormality in the monitoring target area (for example, the arrival of a temperature exceeding a predetermined increase in temperature) in the temperature sensor unit 313C during the second output mode, the monitoring camera 30 starts from the second output mode. Switch to 1 output mode. As a result, the monitoring camera 30 determines that there is an abnormality in the surrounding environment of the solitary elderly PR even if it is detected that an abnormality has occurred in the monitored area, and accurately determines the surrounding situation in the solitary elderly home. The first image data that can be easily grasped can be quickly acquired.

  Moreover, the monitoring camera 30 can recognize that the monitoring target person (for example, the elderly person living alone) is in the monitoring target area based on the first image data obtained by imaging the monitoring target area. For example, the monitoring camera 30 continues the first output mode or switches from the second output mode to the first output mode when it cannot recognize that the solitary elderly person PR is in the monitoring target area. As a result, when the monitoring camera 30 can recognize that the solitary elderly person PR to be monitored is not in the monitoring target area, the first image data that can accurately grasp the surrounding situation in the solitary nursing home is obtained. Can be acquired quickly.

  Also, the monitoring camera 30 wirelessly communicates with the smartphone 50 having the display / operation unit 503, transmits the first image data or the second image data to the smartphone 50, and causes the display / operation unit 503 to display the first image data or the second image data. As a result, the son SN holding the smartphone 50 can browse the first image data or the second image data generated by the monitoring camera 30, and can roughly describe the situation of his / her parent (that is, the elderly living alone). Or accurately.

  Also, the monitoring camera 30 collects the voice of the solitary elderly person PR with the microphone 328 and outputs the voice data for calling the call transmitted from the son SN smartphone 50 through the speaker 329. The monitoring camera 30 transmits the voice data of the voice of the solitary elderly person PR collected by the microphone 328 to the smartphone 50 via the base unit 10 using DECT and the wireless router 60 using wireless LAN. The monitoring camera 30 switches the image output mode from the second output mode to the first output mode when a voice call with the smartphone 50 is started. Thereby, when the voice call is started between the monitoring camera 30 of the son SN and the monitoring camera 30 where the elderly person PR is nearby, the monitoring camera 30 can accurately grasp the situation inside the elderly person living alone. The first image data (normal captured image data) can be acquired, the first image data with clear image quality can be sent to the son SN's smartphone 50, and there is no change in the physical condition of the elderly person living alone in the son SN. The efficiency of confirmation can be improved.

  The monitoring camera 30 receives the operation of the solitary elderly person PR in the operation unit 305, collects the sound of the solitary elderly person PR with the microphone 328, and the voice data for calling the call transmitted from the smartphone 50 of the son SN as a speaker. 329 outputs audio. The monitoring camera 30 transmits the voice data of the voice of the solitary elderly person PR collected by the microphone 328 to the smartphone 50 via the base unit 10 using DECT and the wireless router 60 using wireless LAN. The monitoring camera 30 switches the image output mode from the second output mode to the first output mode when the solitary elderly person PR performs a call response operation at the time of an incoming call from the smartphone 50 of the son SN in the second output mode. As a result, the monitoring camera 30 performs the call response operation for starting a voice call between the son's SN smartphone 50 and the monitoring camera 30 with the solitary elderly person PR nearby. The first image data (normal captured image data) that enables accurate grasp of the situation inside the elderly's house can be acquired, and the first image data with clear image quality can be sent to the son SN's smartphone 50. It is possible to improve the efficiency of checking whether there is any change in the physical condition of the elderly person living alone.

  In addition, the monitoring camera 30 outputs the second image data obtained by performing the blurring process on the first image data using the filter unit F1. As a result, the monitoring camera 30 can acquire the second image data that enables observation of the movement, although the detailed expression of the solitary elderly person PR is not known.

  Also, the monitoring camera 30 outputs second image data obtained by subjecting the first image data to the first image data using the filter unit F1 and the image processing unit DP. As a result, the monitoring camera 30 can acquire the second image data in which the expression of the solitary elderly person PR is not reflected and the detailed movement is not known, but the rough movement such as getting up can be observed.

  Also, the monitoring camera 30 outputs the second image data obtained by performing the blurring process on the first image data using the image processing unit DP. As a result, the monitoring camera 30 can acquire the second image data that enables observation of the movement, although the detailed expression of the solitary elderly person PR is not known.

  In addition, the monitoring camera 30 switches from the second output mode to the first output mode in response to the release signal of the second output mode. As a result, the monitoring camera 30 forcibly switches the image output mode from the second output mode to the first output mode when any change in physical condition occurs in the solitary elderly PR in the solitary elderly home. The first image data that makes it possible to accurately grasp the surrounding situation can be quickly acquired. The release signal of the second output mode is transmitted to the monitoring camera 30 from the external sensor 40E, for example, via the parent device 10 using DECT. For example, the external sensor 40E detects the pressing of an emergency call button prepared in advance in an aged living alone, or detects the pressing of a nurse call button in a nursing facility or a hospital, for example.

  Moreover, in the monitoring system 5, it is not limited to the monitoring camera 30 that detects the movement of the single elderly person PR in the monitoring target area, but may be, for example, a human sensor 40A. As a result, the monitoring camera 30 can protect privacy during imaging of a single elderly person PR to be monitored when the remote elderly person PR is monitored remotely even if the configuration for detecting the movement of the single person elderly person PR is omitted. Therefore, it is possible to achieve both the understanding of the exact situation of the solitary elderly person PR at the time of watching by the watching side (for example, the son SN). That is, the monitoring camera 30 can suppress the deterioration of service quality when watching a single elderly person PR who is estimated to increase in the future with the progress of an aging society.

  The monitoring camera 30 switches from the first output mode to the second output mode when the motion of the solitary elderly person PR is detected by the human sensor 40A during the first output mode. As a result, the monitoring camera 30 generates the data of the captured image when the movement of the solitary elderly person PR is detected. Therefore, for example, the privacy of the solitary elderly person PR who does not want to be monitored is protected. It can be protected accurately.

  In addition, when the monitoring sensor 30 detects that the motion of the solitary elderly person PR is detected after the elapse of a predetermined time from the time when the second monitoring mode is switched from the second output mode to the first output mode, the monitoring camera 30 starts from the second output mode. Switch to output mode. As a result, the monitoring camera 30 has the image output mode set to the first when the single elderly person PR moves a little when the single elderly person PR falls to the floor or the like and the image output mode is switched to the first output mode. It is possible to prevent the switching to the two-output mode, and it is possible to acquire the first image data that makes it possible to grasp the exact situation of the solitary elderly person PR.

  In addition, the monitoring camera 30 may detect abnormalities in the monitoring target area (for example, when the amount of carbon monoxide exceeds a predetermined amount in the second sensor mode, the CO sensor 40B, the smoke sensor 40C, or the window sensor 40D). When the amount exceeds a predetermined amount, or when the window is opened or closed or there is vibration during opening or closing, the second output mode is switched to the first output mode. As a result, the monitoring camera 30 has an abnormality in the environment around the solitary elderly person PR even when the CO sensor 40B, the smoke sensor 40C, or the window sensor 40D detects that an abnormality of the monitoring target area has occurred. Thus, it is possible to quickly acquire the first image data that makes it possible to accurately grasp the surrounding situation in the residence of the elderly living alone.

(Second Embodiment)
In the first embodiment, the monitoring camera 30 changes the image output mode to the first output mode or the presence of the detection of the movement of the single person elderly person PR in the single person old person's house or the detection of abnormality in the single person old person's house. An example of setting to the second output mode has been described.

  In the second embodiment, the monitoring camera 30 starts the image output mode when a voice call (that is, a telephone conversation) between the solitary elderly PR in the solitary nursing home and the son SN holding the smartphone 50 is started. Is set to the first output mode (that is, the image output mode for outputting the first image data having clear image quality).

  The internal configuration of the monitoring system 5 according to the second embodiment is the same as the internal configuration (see FIGS. 1 and 2) of the monitoring system 5 according to the first embodiment. Are simplified or omitted, and different contents will be described.

  Next, an example of switching the image output mode according to external access in the second embodiment will be described with reference to FIG. FIG. 10 is a sequence diagram illustrating in detail an example of an operation procedure for switching the image output mode in accordance with external access according to the second embodiment. 10, the same operations as those in FIG. 7 or FIG. 8 are given the same step numbers, and the description thereof is simplified or omitted, and different contents will be described.

  In FIG. 10, after step S <b> 2, the control unit 309 of the monitoring camera 30 detects the movement of the moving object (for example, the elderly living alone) based on the change (difference) between the frames of the image data obtained from the imaging unit 312. Detect that there was. In addition, the control part 309 may detect that there was a motion of the single person elderly person PR by the infrared sensor part 313B similarly to FIG. In this case, the control unit 309 switches the image output mode from the first output mode to the second output mode, or continues the image output mode in the second output mode (S31). That is, the control unit 309 sets the image output mode to the second output mode. As a result, the monitoring camera 30 generates the data of the captured image when the movement of the solitary elderly person PR is detected. Therefore, for example, the privacy of the solitary elderly person PR who does not want to be monitored is protected. It can be protected accurately.

  Here, after step S31, it is assumed that there is a monitor instruction input operation on the smartphone 50 of the son SN (S6). In this case, the control unit 309 acquires the operation information (see FIG. 7) transmitted in step S8 of FIG. At this time, since the image output mode is set to the second output mode, the control unit 309 causes the second image data obtained from the imaging unit 312 (that is, any one of the fraudulent captured images PC2, PC3, and PC4). ) And the voice data of the voice of the old living alone PR collected by the microphone 328 are transmitted to the base unit 10 via DECT (S37). The base unit 10 receives the moving image data and audio data transmitted from the monitoring camera 30 and transmits the moving image data and audio data to the smartphone 50 via the wireless router 60 (S38). The smartphone 50 displays and reproduces the moving image data transmitted from the parent device 10 on the display / operation unit 503, and further outputs the sound data transmitted from the parent device 10 through the speaker 513. Accordingly, the son SN browses the moving image data based on the image data that has been subjected to the fraudulent processing on the display / operation unit 503 of the smartphone 50, thereby protecting the privacy at the time of imaging of the solitary elderly person PR (his own parent). It is possible to roughly grasp the state of the elderly living alone.

  Here, the external access start method is triggered by the process from the smartphone 50 or the external sensor 40E used by the son SN (S50). The external access start method in step S50 is a process performed to access the monitoring camera 30 from an external device and switch the image output mode of the monitoring camera 30 currently set to the second output mode to the first output mode. It is. In the second embodiment, three types of external access start methods are exemplified. Here, the external access start method will be described with reference to FIGS.

  FIG. 11 is a sequence diagram illustrating in detail a first example of the external access start method. FIG. 12 is a sequence diagram illustrating in detail the second example of the external access start method. FIG. 13 is a sequence diagram illustrating in detail a third example of the external access start method.

  In FIG. 11, when a voice requesting a call to a son SN living alone PR is collected by the smartphone 50 (S <b> 50-1), the smartphone 50 obtains voice data obtained by the voice collection, It transmits to the main | base station 10 via the wireless router 60 (S50-2). The base unit 10 receives the audio data transmitted from the smartphone 50, and transmits the audio data to the monitoring camera 30 via DECT (S50-3). The control unit 309 of the monitoring camera 30 outputs the audio data transmitted from the parent device 10 (that is, the audio data of the audio requesting the call from the son SN) from the speaker 329 (S50-4). When the solitary elderly person PR responds to the sound output from the speaker 329 and performs a call response operation for responding to the call to the operation unit 503 (for example, a predetermined button) (S50-5), the first external access start method Succeeds, and the process of the control unit 309 proceeds to step S41. Although not shown in FIG. 11, the monitoring camera 30 transmits ACK (Acknowledgement) information indicating that the solitary elderly person PR has performed a call response operation to the parent device 10, and further, the parent device 10. And it is preferable to transmit to the smart phone 50 via the wireless router 60. Thus, the son SN can enjoy a sense of security because the elderly person living alone PR responded to his call, and the smartphone 50 sets the image output mode of the monitoring camera 30 to the first. It can be switched to the output mode.

  In FIG. 12, it is assumed that there is no response from the solitary elderly person PR after the voice output in step S50-4. In other words, it is assumed that there is no call response operation by the solitary elderly person PR even after a predetermined time has elapsed since the process of step S50-1. In this case, when predetermined authentication information (password) is input by the operation of the son SN (S50-6), the smartphone 50 transmits the input authentication information to the parent device 10 via the wireless router 60 ( S50-7). The base unit 10 receives the authentication information transmitted from the smartphone 50, and transmits the authentication information to the monitoring camera 30 via DECT (S50-8). The control unit 309 of the monitoring camera 30 uses the authentication information transmitted from the parent device 10 to collate with authentication information corresponding to the external access start method registered in advance in the storage unit 303 (S50-9). ). When the control unit 309 obtains a result that the authentication information has been properly verified (that is, matched with the registered authentication information), the control unit 309 sends an authentication verification result notification including the information to that effect via the DECT. 10 (S50-10), the second external access start method is successful, and the process of the control unit 309 proceeds to step S41. Master device 10 transmits an authentication verification result notification to smartphone 50 via wireless router 60 (S50-11). Thereby, the smart phone 50 can switch the image output mode of the monitoring camera 30 to the first output mode even when the solitary elderly person PR does not react to the call of the son SN. In addition, when the control unit 309 obtains a result that the authentication information is not properly verified (that is, it does not match the registered authentication information), an authentication verification result notification including the information to that effect is obtained. It transmits to the main | base station 10 via DECT (S50-10). Furthermore, base unit 10 transmits an authentication verification result notification to smartphone 50 via wireless router 60 (S50-11). In this case, the external access start method fails, and the processes after step S50 shown in FIG. 10 are not executed.

  In FIG. 13, for example, when the solitary elderly person PR in the solitary elderly person himself inputs the emergency information using the external sensor 40E (S50-21), the external sensor 40E displays the sensor detection information indicating the input of the emergency information, It transmits to the main | base station 10 via DECT (S50-22). As described above, the external sensor 40E detects pressing of the emergency call button prepared in advance in the residence of an elderly person alone by the elderly person PR, or detects pressing of the nurse call button by the elderly person PR in a nursing facility or a hospital, for example. To do. The base unit 10 transmits the sensor detection information transmitted from the external sensor 40E to the smart phone 50 via the wireless router 60 (S50-23), and transmits it to the monitoring camera 30 via DECT (S50-23). ). The control unit 309 checks whether or not the emergency information is input from the external sensor 40E permitted in advance (S50-24). If the control unit 309 can determine that the emergency information is input from the external sensor 40E permitted in advance, the third external access start method is successful, and the process of the control unit 309 proceeds to step S41. Although not shown in FIG. 13, the control unit 309 sends a sensor information collation result notification including information indicating that the emergency information is input from the external sensor 40E permitted in advance to DECT. To the base unit 10 via the network. Master device 10 transmits a sensor information collation result notification to smartphone 50 via wireless router 60. Thereby, the smart phone 50 can receive that the solitary elderly person PR input emergency information by himself, and can make the son SN grasp the situation of the solitary elderly person PR. Also, the solitary elderly person PR can switch the image output mode of the monitoring camera 30 to the first output mode by himself / herself.

  In FIG. 10, when the external access start method in step S50 described above is successful, the control unit 309 of the monitoring camera 30 switches the image output mode from the second output mode to the first output mode (S41). That is, the control unit 309 sets the image output mode to the first output mode. Thereby, the monitoring camera 30 does not detect the movement of the solitary elderly person PR, and therefore can acquire the first image data (normal captured image data) that enables accurate grasp of the situation inside the solitary elderly person's house.

  Further, the control unit 309 converts the moving image data based on the first image data (that is, the data of the normal captured image PC1) obtained from the imaging unit 312 and the audio data of the audio collected by the microphone 328, to DECT. To the base unit 10 (S42). The base unit 10 receives the moving image data and audio data transmitted from the monitoring camera 30 and transmits the moving image data and audio data to the smartphone 50 via the wireless router 60 (S43). The smartphone 50 displays and reproduces the moving image data transmitted from the parent device 10 on the display / operation unit 503, and further outputs the sound data transmitted from the parent device 10 through the speaker 513. Thereby, the son SN who uses the smartphone 50 confirms the clear moving image data and audio data that have not been subjected to the fraud process, for example, the monitoring target region where the elderly single person PR has fallen within the monitoring target region. It is possible to quickly grasp the exact situation in the system and take appropriate measures thereafter.

  Here, when an external access completion operation to the monitoring monitoring camera 30 by the solitary elderly person PR is performed on the operation unit 305 (S61B), the control unit 309 changes the image output mode from the first output mode to the second output mode. (S64). Alternatively, when an external access completion operation by the son SN is performed on the smartphone 50 (S61A), the smartphone 50 transmits operation information of the external access completion operation to the parent device 10 via the wireless router 60 (S62). The base unit 10 receives the operation information of the external access completion operation transmitted from the smartphone 50, and transmits the operation information to the watching monitoring camera 30 via DECT (S63). When acquiring the operation information transmitted in step S63, the control unit 309 switches the image output mode from the first output mode to the second output mode, and sets the image output mode to the second output mode (S64). As a result, the monitoring camera 30 generates data of the captured image when the external access is completed, and thus, for example, the privacy at the time of monitoring (when watching) the solitary elderly person PR who does not want to be monitored is accurately protected. can do. Further, the control unit 309 switches the second image data obtained from the imaging unit 312 (that is, any one of the fraudulent captured images PC2, PC3, PC4) when the image output mode is switched to the second output mode. Data) based on the data) and the voice data of the voice of the solitary elderly person PR collected by the microphone 328 are transmitted to the base unit 10 via DECT (S65). Master device 10 receives the moving image data and audio data transmitted from watching monitoring camera 30, and transmits the moving image data and audio data to smartphone 50 via wireless router 60 (S66). The smartphone 50 displays and reproduces the moving image data transmitted from the parent device 10 on the display / operation unit 503, and further outputs the sound data transmitted from the parent device 10 through the speaker 513. Accordingly, the son SN browses the moving image data based on the image data that has been subjected to the fraudulent processing on the display / operation unit 503 of the smartphone 50, thereby protecting the privacy at the time of imaging of the solitary elderly person PR (his own parent). It is possible to roughly grasp the state of the elderly living alone.

  As described above, the monitoring camera 30 according to the second embodiment makes use of the first output mode and the first image data for outputting the first image data obtained by imaging the monitoring target area, as in the first embodiment. It is possible to switch between the second output mode for outputting the processed second image data. The monitoring camera 30 outputs the first image data in the first output mode, and outputs the second image data in the second output mode. The monitoring camera 30 picks up the voice of the elderly person who lives alone with the microphone 328 and outputs the voice data for calling a call transmitted from the smartphone 50 of the son SN through the speaker 329. The monitoring camera 30 transmits the voice data of the voice of the solitary elderly person PR collected by the microphone 328 to the smartphone 50 via the base unit 10 using DECT and the wireless router 60 using wireless LAN. The monitoring camera 30 switches the image output mode from the second output mode to the first output mode when a voice call with the smartphone 50 is started.

  Thereby, when the voice call is started between the monitoring camera 30 of the son SN and the monitoring camera 30 where the elderly person PR is nearby, the monitoring camera 30 can accurately grasp the situation inside the elderly person living alone. The first image data (normal captured image data) can be acquired, the first image data with clear image quality can be sent to the son SN's smartphone 50, and there is no change in the physical condition of the elderly person living alone in the son SN. The efficiency of confirmation can be improved. Therefore, the monitoring camera 30 protects the privacy at the time of imaging of the single-person elderly person PR to be watched when watching a remote resident (ie, single-person elderly person PR). It is possible to achieve both the understanding of the exact situation of the elderly person who lives alone when watching his son SN). That is, the monitoring camera 30 can suppress the deterioration of service quality when watching a single elderly person PR who is estimated to increase in the future with the progress of an aging society.

  Also, the monitoring camera 30 transmits the first image data or the second image data to the smartphone 50 and causes the display / operation unit 503 to display the first image data or the second image data. As a result, the son SN holding the smartphone 50 can browse the first image data or the second image data generated by the monitoring camera 30, and can roughly describe the situation of his / her parent (that is, the elderly living alone). Or accurately.

  The monitoring camera 30 receives the operation of the solitary elderly person PR in the operation unit 305, collects the sound of the solitary elderly person PR with the microphone 328, and the voice data for calling the call transmitted from the smartphone 50 of the son SN as a speaker. 329 outputs audio. The monitoring camera 30 transmits the voice data of the voice of the solitary elderly person PR collected by the microphone 328 to the smartphone 50 via the base unit 10 using DECT and the wireless router 60 using wireless LAN. The monitoring camera 30 switches the image output mode from the second output mode to the first output mode when the solitary elderly person PR performs a call response operation at the time of an incoming call from the smartphone 50 of the son SN in the second output mode. As a result, the monitoring camera 30 performs the call response operation for starting a voice call between the son's SN smartphone 50 and the monitoring camera 30 with the solitary elderly person PR nearby. The first image data (normal captured image data) that enables accurate grasp of the situation inside the elderly's house can be acquired, and the first image data with clear image quality can be sent to the son SN's smartphone 50. It is possible to improve the efficiency of checking whether there is any change in the physical condition of the elderly person living alone.

  In addition, the monitoring camera 30 switches from the second output mode to the first output mode in response to the release signal of the second output mode. As a result, the monitoring camera 30 forcibly switches the image output mode from the second output mode to the first output mode when any change in physical condition occurs in the solitary elderly PR in the solitary elderly home. The first image data that makes it possible to accurately grasp the surrounding situation can be quickly acquired.

  In addition, the monitoring camera 30 detects the movement of a person (for example, an elderly person living alone) in the monitoring target area. The monitoring camera 30 continues the second output mode when the movement of the solitary elderly person PR is detected during the second output mode. Moreover, the monitoring camera 30 switches from the second output mode to the first output mode when the movement of the solitary elderly person PR is not detected for a predetermined time during the second output mode. As a result, the monitoring camera 30 protects the privacy at the time of imaging of the single elderly person PR to be watched when watching the resident of the elderly living alone (that is, the single person elderly person PR). For example, it is possible to achieve both the grasp of the accurate situation of the single elderly person PR when watching over his son SN). That is, the monitoring camera 30 can suppress the deterioration of service quality when watching a single elderly person PR who is estimated to increase in the future with the progress of an aging society.

  Moreover, the monitoring camera 30 will switch from 1st output mode to 2nd output mode, if the movement of the single person elderly person PR is detected by itself during 1st output mode. As a result, the monitoring camera 30 generates the data of the captured image when the movement of the solitary elderly person PR is detected. Therefore, for example, the privacy of the solitary elderly person PR who does not want to be monitored is protected. It can be protected accurately.

  Moreover, the monitoring camera 30 switches from the second output mode to the first output mode when it detects the movement of the solitary elderly person PR after a predetermined time has elapsed from the time when the second output mode is switched to the first output mode. As a result, the monitoring camera 30 has the image output mode set to the first when the single elderly person PR moves a little when the single elderly person PR falls to the floor or the like and the image output mode is switched to the first output mode. It is possible to prevent the switching to the two-output mode, and it is possible to acquire the first image data that makes it possible to grasp the exact situation of the solitary elderly person PR.

  In addition, when the monitoring camera 30 detects an abnormality in the monitoring target area (for example, the arrival of a temperature exceeding a predetermined increase in temperature) in the temperature sensor unit 313C during the second output mode, the monitoring camera 30 starts from the second output mode. Switch to 1 output mode. As a result, the monitoring camera 30 determines that there is an abnormality in the surrounding environment of the solitary elderly PR even if it is detected that an abnormality has occurred in the monitored area, and accurately determines the surrounding situation in the solitary elderly home. The first image data that can be easily grasped can be quickly acquired.

  Moreover, the monitoring camera 30 can recognize that the monitoring target person (for example, the elderly person living alone) is in the monitoring target area based on the first image data obtained by imaging the monitoring target area. For example, the monitoring camera 30 continues the first output mode or switches from the second output mode to the first output mode when it cannot recognize that the solitary elderly person PR is in the monitoring target area. As a result, when the monitoring camera 30 can recognize that the solitary elderly person PR to be monitored is not in the monitoring target area, the first image data that can accurately grasp the surrounding situation in the solitary nursing home is obtained. Can be acquired quickly.

  In addition, the monitoring camera 30 outputs the second image data obtained by performing the blurring process on the first image data using the filter unit F1. As a result, the monitoring camera 30 can acquire the second image data that enables observation of the movement, although the detailed expression of the solitary elderly person PR is not known.

  Also, the monitoring camera 30 outputs second image data obtained by subjecting the first image data to the first image data using the filter unit F1 and the image processing unit DP. As a result, the monitoring camera 30 can acquire the second image data in which the expression of the solitary elderly person PR is not reflected and the detailed movement is not known, but the rough movement such as getting up can be observed.

  Also, the monitoring camera 30 outputs the second image data obtained by performing the blurring process on the first image data using the image processing unit DP. As a result, the monitoring camera 30 can acquire the second image data that enables observation of the movement, although the detailed expression of the solitary elderly person PR is not known.

  As mentioned above, although embodiment was described referring drawings, it cannot be overemphasized that this invention is not limited to this example. It will be apparent to those skilled in the art that various changes and modifications can be made within the scope of the claims, and these are naturally within the technical scope of the present invention. Understood. In addition, the present invention may be configured by combining the embodiments.

  For example, in the first embodiment, in FIG. 7, it has been described that the movement of the single elderly person PR is not detected by the infrared sensor unit 313 </ b> B in the monitoring camera 30, and the movement of the single person elderly person PR is not detected. However, the fact that the movement of the solitary elderly person PR is detected and that the movement of the solitary elderly person PR is not detected are not detected only by the infrared sensor unit 313B in the monitoring camera 30, for example, It may be detected by the sensor 40A. In this case, sensor detection information indicating that the movement of the solitary elderly person PR is detected and that the movement of the solitary elderly person PR is not detected is transmitted from the human sensor 40A to the watching monitoring camera 30 via DECT.

  For example, in the first embodiment, in FIG. 7, it has been described that the movement of the single elderly person PR is not detected by the infrared sensor unit 313 </ b> B in the monitoring camera 30, and the movement of the single person elderly person PR is not detected. In FIG. 7, a temperature sensor unit 313C may be substituted for the infrared sensor unit 313B. In this case, the control unit 309 determines that an abnormality has occurred in the monitoring target region when the temperature sensor unit 313C detects that the temperature of the monitoring target region exceeds a predetermined temperature, and sets the image output mode. Switch to the first output mode. As a result, the monitoring camera 30 can generate normal captured image data that enables accurate grasping of the status of the monitoring target area when an abnormality occurs in the monitoring target area. Can contribute.

  The present invention balances the protection of the privacy of the resident to be watched over and the grasp of the accurate situation of the resident at the time of watching the resident when watching the resident of the elderly living alone living remotely, This is useful as a monitoring camera, a monitoring system, and a monitoring method for suppressing deterioration in service quality during watching.
