The camera 11 is arranged so that it can image an image target (in the example shown in FIG. 1, the living room (room) RM of the arrangement place). The camera 11 is arranged so that the entire region of the imaging target can be imaged from above the imaging target, generates an image that gives a bird's-eye view of the imaging target, and controls the image of the imaging target (target image) by CU. Output to the processing unit 12a. Preferably, since it is highly probable that the entire region to be imaged can be imaged, the camera 11 is arranged on the ceiling surface of the living room RM where the monitored person Ob is located. Such a camera 11 may be, for example, a visible camera that generates an image of visible light, or, for example, an infrared camera that generates an infrared image so that an image pickup target can be imaged even in a relatively dark place. ..

The CU communication IF unit 13 is a communication circuit connected to the CU control processing unit 12a and for performing communication under the control of the CU control processing unit 12a. The CU communication IF unit 13 generates a communication signal containing data to be transferred input from the CU control processing unit 12a according to the communication protocol used in the network NW of the image recording system MSa, and generates the generated communication signal. It is transmitted to the management server device SVa via the network NW. The SU communication IF unit 13 receives a communication signal from the management server device SVa via the network NW, extracts data from the received communication signal, and processes the extracted data in a format that can be processed by the CU control processing unit 12a. Is converted to and output to the CU control processing unit 12a. The CU communication IF unit 13 is configured to include, for example, a communication interface circuit according to the IEEE802.11 standard or the like.

When the network NW is not used for the wired communication or the wireless communication between the ID device RDa and the image pickup device CUa, for example, the short-range wireless communication is used, the CU communication IF unit 13 may be used. Further, it is configured to include a communication interface circuit corresponding to the short-range wireless communication (for example, a Bluetooth® standard communication interface circuit).

The CU storage unit 14a is a circuit that is connected to the CU control processing unit 12a and stores various predetermined programs and various predetermined data under the control of the CU control processing unit 12a. The various predetermined programs include, for example, a predetermined CU control processing program, and the CU control processing program includes, for example, each part 11, 13, 14a of the image pickup apparatus CUa according to the function of each part. When the CU control program to be controlled or the worker NS enters (enters) the area to be imaged (the living room RM in the present embodiment), the ID device RDa obtains the first specific information (worker ID in the present embodiment). When read, the second specific information of the own machine (camera ID in the present embodiment) and the first specific information read by the ID device RDa are linked to each other to generate the linked information, and the generated linked information is generated. When there is a generation program that outputs (transmits) to the management server device SVa and the first specific information (worker ID in this embodiment) that is managed as described later, an instruction to start imaging is sent to the camera 11. An imaging control program or the like that outputs and outputs an instruction to end imaging to the camera 11 when the managed first specific information is lost is included. The various predetermined data include the second specific information of the own machine (camera ID in this embodiment), the communication address of the management server device SVa, and the CU entry / exit status indicating the entry / exit status of the worker NS with respect to the area to be imaged. It includes data necessary for executing each program, such as status information. The CU storage unit 14a includes, for example, a ROM (Read Only Memory) which is a non-volatile storage element, an EEPROM (Electrically Erasable Programmable Read Only Memory) which is a rewritable non-volatile storage element, and the like. The CU storage unit 14a includes a RAM (Random Access Memory) or the like that serves as a working memory of the so-called CU control processing unit 12a that stores data or the like generated during execution of the predetermined program. Then, the CU storage unit 14a functionally includes an imaging side entry / exit status information storage unit (CU entry / exit status information storage unit) 141a that stores the CU entry / exit status information.

The CU entry / exit status information storage unit 141a stores the CU entry / exit status information indicating the entry / exit status of the worker NS with respect to the region to be imaged. In the present embodiment, the CU entry / exit status information represents the entry / exit status of the worker NS with respect to the region to be imaged, depending on whether or not the first specific information is stored, and in the present embodiment, the worker ID is stored. More specifically, as shown in FIG. 7, the CU entry / exit status information storage unit 141a includes a worker ID field 1411 for registering a worker ID, and has a record for each worker ID. Information table (CU entry / exit status information table) MTa is stored. When the worker ID is notified from the ID device RDa, if the notified worker ID is not registered in the worker ID field 1411 of the CU entry / exit status information table MTa, a new record is generated. The notified worker ID is registered in the worker ID field 1411 of the newly generated record. As a result, the situation in which the worker NS having the worker ID enters (enters or stays in the room) in the area to be imaged is stored in the CU entry / exit status information storage unit 141a. On the other hand, when the worker ID is notified from the ID device RDa, if the notified worker ID is already registered in the worker ID field 1411 of the CU entry / exit status information table MTa, the notification is given. The record for registering the worker ID is deleted (the worker ID is deleted from the worker ID field 1411). As a result, the situation in which the worker NS having the worker ID leaves (leaves or is absent) from the area to be imaged is stored in the CU entry / exit status information storage unit 141a.

The CU control processing unit 12a controls each unit 11, 13, 14a of the image pickup apparatus CUa according to the function of each unit, images the image pickup target, generates an image, and uses the generated image as a management server device. This is a circuit for notifying SVa. Then, the CU control processing unit 12a manages the entry / exit status of the worker NS with respect to the region to be imaged, and when notifying the management server device SVa of the generated image, the CU control processing unit 12a stores the own machine in advance in the CU storage unit 14a. The generated image is notified to the management server device SVa together with the second specific information (camera ID in the present embodiment). The CU control processing unit 12a is configured to include, for example, a CPU (Central Processing Unit) and peripheral circuits thereof. The CU control processing unit 12a functionally includes an imaging side control unit (CU control unit) 121, a generation unit 122a, and an imaging control unit 123 by executing the CU control processing program.

The CU control unit 121 controls each of the units 11, 13, and 14a of the image pickup apparatus CUa according to the functions of the respective portions, and controls the entire image pickup apparatus CUa. The CU control unit 121 clocks in the year, month, day, hour, minute, and second.

The generation unit 122a reads the first specific information (worker ID in the present embodiment) by the ID device RDa when the worker NS enters (enters) the area to be imaged (the living room RM in the present embodiment). In this case, the second specific information of the own machine (camera ID in the present embodiment) and the first specific information read by the ID device RDa are linked to each other to generate the linked information, and the generated linked information is managed. It outputs (transmits) to the server device SVa.

In the present embodiment, the generation unit 122a generates and transmits the association information with the image pickup side management processing unit (CU management processing unit) 1221a for managing the entry / exit status of the worker NS with respect to the area to be imaged. The notification processing unit 1222 of the above is functionally provided.

The CU management processing unit 1221a manages the first specific information (worker ID in the present embodiment) read by the ID device RDa. In the present embodiment, in order to control the start and end of imaging by the camera 11 by the imaging control unit 123, the CU management processing unit 1221a further reads the first specific information already managed by the ID device RDa. In that case, the management of the first specific information that has already been managed is released. More specifically, when the CU management processing unit 1221a reads the ID device RDa and the ID device RDa notifies the worker ID, the notified worker ID is transmitted to the CU entry / exit status information storage unit 141a. If it is not registered in the worker ID field 1411 of the stored CU entry / exit status information table MTa, a new record is generated, and the work notified in the worker ID field 1411 of this newly generated record is performed. Register the person ID. On the other hand, when the CU management processing unit 1221a reads the ID device RDa and the ID device RDa notifies the worker ID, the notified worker ID is stored in the CU entry / exit status information storage unit 141a. When registered in the worker ID field 1411 of the CU entry / exit status information table MTa, the record for registering the notified worker ID is deleted. In this way, the CU management processing unit 1221a manages the entry / exit status of the worker NS with respect to the area to be imaged, depending on whether or not the worker ID is stored.

The notification processing unit 1222 generates the association information according to the management result by the CU management processing unit 1221a, and notifies (transmits) the generated association information to the management server device SVa. More specifically, when the notification processing unit 1222 generates a new record in the CU entry / exit status information table MTa and registers the notified worker ID in the worker ID field 1411 as described above, the notification processing unit 1222 may register the notified worker ID in the worker ID field 1411. It is determined that the worker NS has entered the area to be imaged, and the camera ID of the own machine and the worker ID notified from the ID device RDa read by the ID device RDa are linked to each other to generate the link information. The generated linking information and a communication signal (linking information notification communication signal) accommodating the current time as the imaging start time are generated to the management server device SVa, and the generated linking information notification communication signal is generated. It is transmitted to the management server device SVa by CU communication IF13.

The image pickup control unit 123 outputs each instruction of start / end of image pickup to the camera 11 based on the management result of the entry / exit status managed by the generation unit 122a as described above. More specifically, the imaging control unit 123 starts imaging when there is the first specific information (worker ID in the present embodiment) managed by the CU management processing unit 1221a of the generation unit 122a. The start instruction is output to the camera 11, and when the managed first specific information is lost, the imaging end instruction to end the imaging is output to the camera 11.

When the camera 11 receives the instruction to start imaging from the imaging control unit 123 as described above, the camera 11 starts imaging, outputs the image generated by this imaging to the CU control processing unit 12a, and the CU control processing unit 12a receives the instruction to start imaging. This image is temporarily stored in the CU storage unit 14a. On the other hand, when the camera 11 receives the instruction to end the imaging from the imaging control unit 123, the camera 11 ends the imaging. When the imaging is completed, the CU control processing unit 12a transmits the image temporarily stored in the CU storage unit 14a to the management server device SVa. More specifically, the CU control processing unit 12a is a communication accommodating the image (image data) temporarily stored in the CU storage unit 14a, the camera ID of the own machine, and the current time as the imaging end time. A signal (image notification communication signal) is generated to the management server device SVa, and the generated image notification communication signal is transmitted to the management server device SVa by the CU communication IF13. When the CU control processing unit 12a transmits the image temporarily stored in the CU storage unit 14a to the management server device SVa, the CU control processing unit 12a deletes (erases) the image from the CU storage unit 14a.

Next, the operation of this embodiment will be described. FIG. 6 is a sequence diagram showing the operation of the first embodiment regarding image recording in the image recording system as an example. FIG. 7 is a diagram for explaining the transition of the CU entry / exit status information table in the operation shown in FIG. In FIG. 7, the CU entry / exit status information tables MTa-t11, MTa-t12, and MTa-t13 for each of time t11, time t12, and time t13 are shown in order from the left side of the paper to the right side of the paper. FIG. 8 is a diagram showing an example of an extraction result display screen that displays an extraction result of extracting an image for a desired worker from a plurality of image files displayed on the management server device.

In the image recording system MSa having the above configuration, each device CUa, RDa, SVa, and TAa executes necessary initialization of each part when the power is turned on, and starts its operation. In the image pickup apparatus CUa, the CU control processing unit 12a is functionally configured with the CU control unit 121, the generation unit 122a, and the imaging control unit 123 by executing the CU control processing program. In the management server device SVa, the SV control processing unit 22a is functionally configured with the SV control unit 221 and the image storage processing unit 222a by executing the SV control processing program. Then, in the mobile terminal device TAa, the TA control processing unit 32a is functionally configured with the TA control unit 321 and the worker ID information output processing unit 322 by executing the TA control processing program.

Then, the image recording system MSa collects each image from each image pickup apparatus CUa-1 to CUa-3 by the operation of the first embodiment regarding image recording as follows, and records (stores) each image. Here, in the following description, as an example, at the beginning, for example, at the time of login operation, the worker ID; "ID-NA" is input to the mobile terminal device TAa-1 carried by the worker NS-1. It is assumed that the worker ID; "ID-NA" is stored in advance. Then, the worker NS is not present in the living room RM-1, and the CU entry / exit status information table MTa-t11 stored in the CU entry / exit status information storage unit 141a is shown on the left side of the paper in FIG. , It is assumed that the worker ID is not registered (memorized).

In FIG. 6, the worker NS-1 enters (enters) the living room RM-1 (area to be imaged) of the monitored person Ob-1 in order to perform a predetermined work such as nursing, nursing care, or cleaning. At that time, the portable terminal device TAa-1 that is carried is brought close to the ID device RDa-1 provided corresponding to the living room RM-1, and the worker ID (first specific information) is read. Perform the operation (C11).

When the mobile terminal device TAa-1 and the ID device RDa-1 are brought close to each other, the mobile terminal device TAa-1 is subjected to the TA storage unit 33a by the worker ID information output processing unit 325 of the TA control processing unit 32a. The worker ID; "ID-NA" stored in the worker ID information storage unit 332 is taken out, and the taken out worker ID; "ID-NA" is transmitted by the TAIF unit 37 (the worker ID; ". The TAIF unit 37 transmits a communication signal accommodating the "ID-NA"), and the ID device RDa-1 receives the worker ID; "ID-NA" transmitted from the mobile terminal device TAa-1. The worker ID is read from the mobile terminal device TAa-1 (C12).

Subsequently, the ID device RDa-1 notifies the image pickup device CUa-1 provided in the living room RM-1 of the worker ID; "ID-NA" read from the mobile terminal device TAa-1 (the worker). ID: A communication signal accommodating "ID-NA" is transmitted to the imaging device CUa-1) (C13).

Upon receiving the notification of the worker ID; "ID-NA" from the ID device RDa-1, the imaging device CUa-1 is a CU control processing unit for processing the entry / exit status of the worker NS with respect to the living room RM-1. The CU management processing unit 1221a of the generation unit 122a in 12a manages the worker ID; "ID-NA" notified from the ID device RDa-1 (C14). More specifically, the notified worker ID; "ID-NA" is not registered in the worker ID field 1411 of the CU entry / exit status information table MTa stored in the CU entry / exit status information storage unit 141a. In this case, the CU management processing unit 1221a generates a new record, and registers the notified worker ID; "ID-NA" in the worker ID field 1411 of the newly generated record. On the other hand, when the notified worker ID; "ID-NA" is registered in the worker ID field 1411 of the CU entry / exit status information table MTa stored in the CU entry / exit status information storage unit 141a, The CU management processing unit 1221a deletes the record for registering the notified worker ID; "ID-NA" (deletes the worker ID from the worker ID field 1411).

In the example shown in FIG. 7, when the notification of the worker ID; "ID-NA" is received from the ID device RDa-1, the notified worker ID; "ID-NA" is the CU entry / exit status information storage unit 141a. Since it is not registered in the worker ID field 1411 of the CU entry / exit status information table MTa-t11 stored in the CU management processing unit 1221a, the CU management processing unit 1221a generates a new record, and the worker ID of the newly generated record is generated. The notified worker ID; "ID-NA" is registered in the field 1411. As a result, the CU entry / exit status information table MTa-t11 shown on the left side of the paper in FIG. 7 becomes the CU entry / exit status information table MTa-t12 shown in the center of the paper, and the CU entry / exit status information storage unit 141a is filled with the worker ID; "ID-". The CU entry / exit status information table MTa-t12 in which "NA" is registered is stored.

Subsequently, since the worker ID; "ID-NA" is present in the CU entry / exit status information table MTa-t12 managed by the CU management processing unit 1221a, the image pickup apparatus CUa-1 can start imaging. The image pickup control unit 123 outputs an instruction to start image pickup to the camera 11 (C15). When the camera 11 receives an instruction to start imaging from the imaging control unit 123, the camera 11 starts imaging, outputs an image generated by this imaging to the CU control processing unit 12a, and the CU control processing unit 12a outputs this image to the CU control processing unit 12a. It is temporarily stored in the storage unit 14a. As a result, an image (moving image in the present embodiment) of the imaged object is generated and stored in the CU storage unit 14a. The moving image may have a normal frame rate such as 24 fps or 30 fps, or may have a frame rate lower than the normal frame rate such as 15 fps, 10 fps or 5 fps in order to reduce the data capacity. ..

Subsequently, since the worker ID is newly registered in the process C14, the imaging device CUa-1 uses the notification processing unit 1222 of the generation unit 122a in the CU control processing unit 12a to notify the association information. The camera ID; "CU-1" and the worker ID; "ID-NA" read and notified by the ID device RDa are linked to each other to generate linking information, and the generated linking information and the imaging start time are generated. The current time is notified to the management server device SVa (the linking information notification communication signal containing the linking information and the current time (imaging start time) is transmitted to the management server device SVa) (C16).

When the image pickup device CUa-1 notifies the linking information and the imaging start time (when the linking information notification communication signal is received from the image pickup device CUa-1), the management server device SVa receives the linking information and the imaging start time. Is temporarily temporarily stored in the SV storage unit 23a (C17).

Then, upon completion of the work, the worker NS-1 present in the living room RM-1 transfers the portable terminal device TAa-1 carried by the worker NS-1 to the living room RM-1 when leaving the room. A reading operation is performed in which the worker ID; "ID-NA" is read in close proximity to the corresponding ID device RDa-1 (C21).

When the mobile terminal device TAa-1 and the ID device RDa-1 are close to each other, in the mobile terminal device TAa-1, the worker ID information output processing unit 325 uses the worker ID as in the above-mentioned processing C12. The worker ID; "ID-NA" stored in the information storage unit 332a is taken out, and the taken out worker ID; "ID-NA" is transmitted by the TAIF unit 37, and the ID device RDa-1 is a mobile terminal. The worker ID; "ID-NA" transmitted from the device TAa-1 is received, and the worker ID; "ID-NA" is read from the mobile terminal device TAa-1 (C22).

Subsequently, the ID device RDa-1 obtains the worker ID; "ID-NA" read from the mobile terminal device TAa-1 in the same manner as the above-described processing C13, and the image pickup device CUa provided in the living room RM-1. Notify -1 (C23).

Upon receiving the notification of the worker ID; "ID-NA" from the ID device RDa-1, the imaging device CUa-1 is a CU management processing unit in order to process the entry / exit status of the worker NS with respect to the living room RM-1. The worker ID; "ID-NA" notified from the ID device RDa-1 by 1221a is managed (C24). More specifically, here, as shown in the center of the paper in FIG. 7, the notified worker ID; "ID-NA" is stored in the CU entry / exit status information storage unit 141a. Since it is registered in the worker ID field 1411 of the table MTa-t12, the CU management processing unit 1221a deletes the record for registering the notified worker ID; "ID-NA". As a result, the CU entry / exit status information table MTa-t12 shown in the center of the paper in FIG. 7 becomes the CU entry / exit status information table MTa-t13 shown on the right side of the paper, and the SU entry / exit status information storage unit 141a has the worker ID; "ID-". The record in which "NA" is registered disappears, and the CU entry / exit status information table MTa-t13 in which no worker ID is registered is stored. Since the notification processing unit 1222 did not register the worker ID, it does not generate the association information and does not transmit the association information notification communication signal.

Subsequently, since there is no worker ID in the CU entry / exit status information table MTa-t13 managed by the CU management processing unit 1221a, the image pickup apparatus CUa-1 is subjected to the image pickup control unit 123 in order to end the image pickup. An instruction to end imaging is output to the camera 11 (C25). When the camera 11 receives the instruction to end the imaging from the imaging control unit 123, the camera 11 ends the imaging.

When the imaging is completed, the imaging device CUa-1 transmits the image temporarily stored in the CU storage unit 14a to the management server device SVa by the CU control processing unit 12a (C26). More specifically, the CU control processing unit 12a transmits an image notification communication signal including the image temporarily stored in the CU storage unit 14a, the camera ID of the own machine, and the current time as the imaging end time. Send to the management server device SVa.

Upon receiving the notification of the image from the image pickup device CUa (when the image notification communication signal is received from the image pickup device CUa), the management server device SVa receives the image notification communication signal from the image pickup device CUa by the image storage processing unit 222a of the SV control processing unit 22a. The image is associated with the worker ID as the first specific information and stored in the image storage unit 231a (C27). More specifically, the image storage processing unit 222a stores the image accommodated in the received image notification communication signal in the image storage unit 231a with an image file name. Next, the image storage processing unit 222a matches the camera ID accommodated in the received image notification communication signal from the camera IDs of the associated information temporarily stored in the SV storage unit 23a. The camera ID to be used is selected (searched), the worker ID and the imaging start time in the association information having the selected camera ID, and the image (the image file name) accommodated in the received image notification communication signal. And the imaging end time are associated with each other. Next, the image storage processing unit 222a assigns a serial number as an image ID to the pair of associated worker IDs, the imaging start time, the image file name, and the imaging end time. Then, the image storage processing unit 222a generates a new record in the image information table PT stored in the image storage unit 231a, and the image ID field 2311, the start time subfield 23121, and the end time subfield in the generated record are generated. 23122, the image file name field 2313 and the worker ID field 2314, respectively, the image ID, the imaging start time (time accommodated in the association information notification communication signal), and the imaging end time (in the image notification communication signal). (Accommodated time), image file name and worker ID are registered respectively. Then, the image storage processing unit 222a erases (deletes) the association information and the imaging start time temporarily stored in the SV storage unit 23a.

By such an operation, the image recording system MSa collects each image from each image pickup device CUa-1 to CUa-3 arranged in each living room RM-1 to RM-3, and associates a worker ID with each image. Attach and memorize (record).

Then, when extracting an image for the desired (purpose) worker NS, for example, an operator such as the boss of the worker NS may use the SV input unit 24 as a search key to perform the worker corresponding to the desired worker NS. Enter the ID and enter the instruction to start the search.

When the management server device SVa receives the worker ID of the search key and the instruction to start the search, the SV control processing unit 22a selects the worker ID of the search key from the images stored in the image storage unit 231 by the SV control processing unit 22a. The image with is searched and output to the SV output unit 25. More specifically, when the worker ID of the search key; "ID-NA" is received, the SV control processing unit 22a enters the worker ID field 2314 of the image information table PT stored in the image storage unit 231a. The received worker ID; the record for registering "ID-NA" is extracted, and the image ID and the recording time (recording time) registered in the fields 2311, 2312 (2311, 23122), 2313, 2314 in the extracted record are extracted. Imaging start time, imaging end time), image file name and worker ID are extracted, and the extracted image ID, recording time (imaging start time, imaging end time), image file name and worker ID are obtained, for example, FIG. As shown in, it is displayed on the SV output unit 25 in a list format. The extraction result display screen 61 of the example shown in FIG. 8 has an image ID display field 611 for displaying the extracted image ID, a recording time display field 612 for displaying the extracted recording time, and the extracted image file name. The image file name display field 613 for displaying the above and the worker ID display field 614 for displaying the extracted worker ID are provided, and the number of display lines corresponding to the number of the extracted records is provided. The recording time display field 612 includes a start time display field 6121 and an end time display field 6122 for displaying the taken-out imaging start time and imaging end time, respectively. Then, when the image file name displayed in the image file name display field 613 is input from the SV input unit 24 (for example, when the cursor is moved to the image file name with the mouse and left-clicked), the SV control processing unit 22a inputs this input. An image having the manipulated image file name is taken out from the image storage unit 231 and the taken out image is reproduced and displayed on the SV output unit 25. The image is reproduced and displayed on the SV output unit 25, for example, instead of the extraction result display screen 61. In this case, when the reproduction of the image is completed, the extraction result display screen 61 is displayed on the SV output unit 25. Alternatively, for example, the image is reproduced and displayed on the SV output unit 25 in a new window. This allows the operator to refer to an image for the desired worker NS.

As described above, the image recording system MSa and the image recording method implemented in the image recording system MSa in the first embodiment are described when a predetermined worker NS enters the area to be imaged (in the present embodiment, the living room RM). One of the first and second specific information (worker ID as the first specific information in the present embodiment) is read and the other specific information (camera ID as the second specific information in the present embodiment) is read. ) Is used to generate linked information in which the first and second specific information are linked to each other, while an image and its second specific information are obtained from the image pickup apparatus CUa. Then, the image recording system MSa and the image recording method convert the image into the first specific information based on the second specific information received from the image pickup device CUa together with the image and the association information received from the image pickup device CUa. It is linked and stored in the image storage unit 231a. That is, the image recording system MSa and the image recording method obtain the first specific information corresponding to the second specific information associated with the image from the associated information, and obtain the obtained first specific information. The images are associated with each other and stored in the image storage unit 231a. Therefore, the image recording system MSa and the image recording method can more easily extract an image for a desired (objective) worker NS by referring to the first specific information associated with the image. Therefore, the boss of the worker NS can grasp the dexterity, appropriateness, politeness, etc. of the work in the worker NS by referring to the image for the worker NS, and after grasping the actual situation of the worker NS. Then, the worker NS can be instructed.

The image recording system MSa and the image recording method output an instruction to start imaging to the camera 11 when there is one of the specific information under control (worker ID as the first specific information in the present embodiment). When one of the specific information under control is lost, an instruction to end imaging is output to the camera 11. That is, the image recording system MSa and the image recording method instruct the start of imaging when the worker NS enters the area to be imaged, and perform imaging while at least one worker NS is present. Continue, and when the worker NS leaves, instruct the end of the imaging. Therefore, the image recording system MSa and the image recording method can store an image in the image storage unit 221a while at least one worker NS is located in the area to be imaged, and is irrelevant to the location of the worker NS. The data capacity of the image can be reduced as compared with the case of continuous imaging (for example, 24-hour imaging). The boss of the worker NS can also quickly observe the work of the worker NS.

Next, another embodiment will be described.

Then, the image cutout storage processing unit 2221 deletes (deletes) the registered start time, end time, and worker ID from the SV storage unit 23b together with the camera ID associated with them. The image cutout storage processing unit 2221 performs such processing in the SV storage unit 23b temporarily stored in the SV storage unit 23b by the SV management processing unit 223. Repeat until the camera ID, start time and end time are basically gone (until they are all erased).

Depending on the extracted start time and end time and the notification timing, the original image file name including only the extracted start time and the original image file name including only the extracted end time may be extracted. In this case, the image cutout storage processing unit 2221 cuts out from the original image having the original image file name including only the start time from the start time to the end of the original image, and includes only the end time. From the original image having the image file name, the period from the beginning to the end time is cut out, and these are connected to generate a new image. In this case, depending on the relationship between the notification timing and the cutting timing, the original image having the original image file name including only the extracted end time is stored in the original image storage unit 232 at the time of the cutting timing. It may not be there. At this time, the image is not cut out from the original image, and the pair of worker IDs, camera IDs, start time and end time associated with each other are temporarily erased temporarily stored in the SV storage unit 23b. Instead, at the next cutting timing, the pair of worker IDs, camera IDs, start time, and end time associated with each other temporarily stored in the SV storage unit 23b are carried over (temporary).

Since the TA control unit 321 in the mobile terminal device TAb of the second embodiment is the same as the TA control unit 321 in the mobile terminal device TAa of the first embodiment, the description thereof will be omitted.

The reading notification processing unit 323 reads the second specific information (camera ID in the present embodiment) from the ID device RDb and has the first specific information (work in the present embodiment) previously stored in the worker ID information storage unit 332. The person ID) is notified to the management server device SVb as association information together with the read second specific information.

In the present embodiment, the ID device RDb is a plate on which a one-dimensional code or a two-dimensional code representing a camera ID is printed as the second specific information. 323 identifies and analyzes the one-dimensional code or the two-dimensional code by executing a predetermined image process on the image (image data) obtained by capturing the one-dimensional code or the two-dimensional code with the camera. Then, the second specific information (camera ID) is read from this analysis result. Then, the reading notification processing unit 323 generates the linking information by linking the read second specific information (camera ID) and the worker ID stored in the worker ID information storage unit 331 with each other. A communication signal (linking information notification communication signal) accommodating the generated linking information and the current time is generated to the management server device SVb, and the generated linking information notification communication signal is transmitted by the TA communication IF unit 31. ..

When the ID device RDb is an IC card (RF tag) or a magnetic card, the mobile terminal device TAb further includes a card reader of the IC card or the magnetic card, and the reading notification processing unit 323 is the card reader. The second specific information (camera ID) is read from the IC card or the magnetic card, and the association information notification communication signal is transmitted to the management server device SVb. Alternatively, when the ID device RDb is a tablet terminal device, the reading notification processing unit 323 reads the second specific information (camera ID) from the tablet terminal device by the TAIF unit 37, and the association information notification communication signal. Is transmitted to the management server device SVb.

In the second embodiment, the mobile terminal device TAb specifies the first specific information for identifying the worker and the imaging unit corresponding to the imaging target when a predetermined worker enters the area to be imaged. Corresponds to another example of the reading unit that reads one specific information of the second specific information. Then, in the second embodiment, the mobile terminal device TAb further has the other specific information of the first and second specific information in advance, and when the reading unit reads the one specific information, the mobile terminal device TAb further has the other specific information. As an example of a generation unit that generates association information in which the other specific information and the one specific information read by the reading unit are associated with each other and outputs the generated association information to the image storage processing unit. Is also equivalent.

Next, the operation of this embodiment will be described. FIG. 12 is a sequence diagram showing the operation of the second embodiment regarding image recording in the image recording system as an example. FIG. 13 is a diagram for explaining the transition of the SV entry / exit status information table in the operation shown in FIG. In FIG. 13, the SV entry / exit status information tables MTb-t21, MTb-t22, and MTb-t23 for each of time t21, time t22, and time t23 are shown in order from the left side of the paper to the right side of the paper.

In the image recording system MSb having the above configuration, each device CUb, SVb, and TAb executes necessary initialization of each part when the power is turned on, and starts its operation. In the management server device SVb, the SV control processing unit 22b is functionally configured with the SV control unit 221 and the image storage processing unit 222b and the SV management processing unit 223 by executing the SV control processing program. The image cutout storage processing unit 2221 and the original image storage processing unit 2222 are functionally configured in 222b. Then, in the mobile terminal device TAb, the TA control processing unit 32b is functionally configured with the TA control unit 321 and the reading notification processing unit 323 by executing the TA control processing program.

Then, the image recording system MSb collects each image from each image pickup apparatus CUb-1 to CUb-3 by the operation of the second embodiment relating to the following image recording, and records (stores) each image. Here, in the following description, as an example, at the beginning, for example, at the time of login operation, the worker ID; "ID-NA" is input to the mobile terminal device TAa-1 carried by the worker NS-1. It is assumed that the worker ID; "ID-NA" is stored in advance. Then, the worker NS is not present in the living room RM-1, and the SV entry / exit status information table MTb-t21 stored in the SV entry / exit status information storage unit 233 is shown on the left side of the paper in FIG. , It is assumed that the worker ID is not registered (memorized).

In FIG. 12, for example, in order to perform a predetermined work, when the worker NS-1 enters the room RM-1 of the monitored person Ob, he / she carries the portable terminal device TAb-1 in the room. A reading operation is performed (C111) in which the camera ID (second specific information) is read in close proximity to the ID device RDb-1 provided corresponding to the RM-1.

When the mobile terminal device TAb-1 and the ID device RDb-1 are close to each other, the mobile terminal device TAb-1 is seconded from the ID device RDb-1 by the reading notification processing unit 323 of the TA control processing unit 32b. The camera ID; "CU-1" is read as specific information (C112).

Subsequently, the portable terminal device TAb-1 stores the worker ID; "ID-NA" stored as the first specific information in the worker ID information storage unit 331 of the TA storage unit 33 by the reading notification processing unit 323. The camera ID; "CU-1" and the worker ID; “ID-NA” taken out and read by the processing C112 are linked to each other to generate the linking information, and the generated linking information and the current time are generated. A linking information notification communication signal accommodating the above is generated to the management server device SVb, and the generated linking information notification communication signal is transmitted by the TA communication IF unit 31 (C113).

Upon receiving the association information notification communication signal from the mobile terminal device TAb-1, the management server device SVb is the SV management processing unit of the SV control processing unit 22b in order to process the entry / exit status of the worker NS with respect to the area to be imaged. 223 manages the camera ID; “CU-1” and the worker ID; “ID-NA” transmitted from the mobile terminal device TAb-1 (C114). More specifically, the SV management processing unit 223 first transfers the camera ID of the association information stored in the received association information notification communication signal; "CU-1" to the SV entry / exit status information storage unit 233. A record to be registered in the camera ID field 2331 of the stored SV entry / exit status information table MTb is selected (searched). Next, the SV management processing unit 223 registers the worker ID of the linking information stored in the received linking information notification communication signal; "ID-NA" in the worker ID field 2332 of the selected record. Check if it is done. When the receiving worker ID; "ID-NA" is not registered in the worker ID field 2332 in the selected record, the SV management processing unit 223 raises the worker ID field 2332 in the selected record. The reception worker ID; "ID-NA" is registered in. On the other hand, when the receiving worker ID; "ID-NA" is registered in the worker ID field 2342 in the selected record, the SV management processing unit 223 has the worker ID in the selected record. The worker ID is deleted (erased) from the field 2342.

In the example shown in FIG. 13, when the camera ID; "CU-1" and the worker ID; "ID-NA" are received from the mobile terminal device TAb-1 by the association information notification communication signal, the SV entry / exit status information storage unit 233 In the SV entry / exit status information table MTb-t21 stored in, the received camera ID; the received worker ID; Since the "ID-NA" is not registered, the SV management processing unit 223 registers the received worker ID; "ID-NA" in the worker ID field 2332. As a result, the SV entry / exit status information table MTb-t21 shown on the left side of the paper in FIG. 13 becomes the SV entry / exit status information table MTb-t22 shown in the center of the paper, and the camera ID; The SV entry / exit status information table MTb-t22 in which the worker ID; “ID-NA” is registered is stored in the worker ID field 2332 in the record in which “” is registered in the camera ID field 2331.

Subsequently, when the SV entry / exit status information table MTb-t22 is updated, the SV management processing unit 223 temporarily temporarily stores the received association information in the SV storage unit 23b (C115). More specifically, when the worker ID is registered from the state where there is no worker ID in the worker ID field 2332, the SV management processing unit 223 performs the time accommodated in the received association information notification communication signal. Is used as the start time, the registered worker ID, the camera ID associated with the worker ID in the association information, and the start time are associated with each other and temporarily stored in the SV storage unit 23b. When the worker ID is further registered from the state where the worker ID is present in the worker ID field 2332, the SV management processing unit 223 transfers the worker ID registered in the worker ID field 2332 to the SV storage unit 23b. Temporarily stored in the SV storage unit 23b in association with the temporarily stored worker ID, camera ID, and start time associated with each other. When there is no worker ID from the state where there is at least one worker ID in the worker ID field 2332, the SV management processing unit 223 uses a string containing the link information of the worker ID deleted from this registration. The time stored in the attached information notification communication signal is set as the end time, and this end time is further associated with the worker ID, the camera ID, and the start time that are already tentatively stored in the SV storage unit 23b. Temporarily stored in the SV storage unit 23b.

In the example shown in FIG. 13, since the worker ID is registered from the state where there is no worker ID in the worker ID field 2332, the SV management processing unit 223 sends the received association information notification communication signal to the received link information notification communication signal. With the accommodated time as the start time, the registered worker ID, the camera ID linked to the worker ID in the linking information, and the start time are linked to each other and temporarily stored in the SV storage unit 23b. To do.

Then, for example, upon completion of the work, the worker NS-1 who is present in the living room RM-1 uses the portable terminal device TAb-1 carried by the worker NS-1 when leaving the living room RM-1. A reading operation is performed in which the camera ID is read by bringing the camera ID close to the ID device RDb-1 provided corresponding to the above (C121).

When the mobile terminal device TAb-1 and the ID device RDb-1 are in close proximity to each other, the mobile terminal device TAb-1 receives the camera ID as the second specific information from the ID device RDb-1 in the same manner as the above-described processing C112. Read "CU-1" (C122).

Subsequently, the mobile terminal device TAb-1 takes out the stored worker ID; "ID-NA" and reads the camera ID; "CU-1" and the above in the process C122, similarly to the above-mentioned process C113. The extracted worker ID; "ID-NA" is associated with each other to generate association information, and the generated association information and the association information notification communication signal accommodating the current time are transmitted to the management server device SVb. (C123).

Upon receiving the linked information information communication signal from the mobile terminal device TAb-1, the management server device SVb receives the camera ID transmitted from the mobile terminal device TAb-1 by the SV management processing unit 223, similarly to the above-mentioned processing C114. "CU-1" and worker ID; "ID-NA" are managed (C124).

In the example shown in FIG. 13, when the camera ID; "CU-1" and the worker ID; "ID-NA" are received from the mobile terminal device TAb-1 by the association information notification communication signal, the SV entry / exit status information storage unit 233 In the SV entry / exit status information table MTb-t22 stored in, the received camera ID; the received worker ID; Since the "ID-NA" is registered, the SV management processing unit 223 deletes (deletes) the received worker ID; "ID-NA" from the worker ID field 2332. As a result, the SV entry / exit status information table MTb-t22 shown in the center of the paper in FIG. 13 becomes the SV entry / exit status information table MTb-t23 shown on the right side of the paper, and the camera ID; "CU-1" is displayed in the SV entry / exit status information storage unit 233. The SV entry / exit status information table MTb-t23 in which the worker ID is not registered is stored in the worker ID field 2332 in the record in which the camera ID field 2331 is registered.

Subsequently, when the SV entry / exit status information table MTb-t23 is updated, the SV management processing unit 223 temporarily stores the received association information in the SV storage unit 23b in the same manner as the above-mentioned processing C115. (C125).

In the example shown in FIG. 13, since there is no worker ID from the state where at least one worker ID is present in the worker ID field 2332, the SV management processing unit 223 deletes the work from this registration. The link information notification communication signal accommodating the link information of the person ID is set as the end time, and this end time is tentatively stored in the SV storage unit 23b. It is temporarily stored in the SV storage unit 23b in association with the camera ID and the start time.

By such an operation, the association information regarding the worker NS who has entered and exited the area to be imaged is temporarily temporarily stored and accumulated in the SV storage unit 23b together with the start time and the end time.

On the other hand, the image pickup apparatus CUb constantly captures an image pickup target by the camera 11 to generate an image, temporarily stores the generated image in the CU storage unit 14b, and accumulates the generated image. At the notification timing, the image pickup device CUb receives an image (image data) generated by the camera 11 and temporarily stored in the CU storage unit 14b, its own camera ID, and the current time as the image pickup end time. A signal is generated, and the generated image notification communication signal is transmitted to the management server device SVb (C131).

When the image notification communication signal is received from the image pickup device CUb, the management server device SVb receives the image (image data) accommodated in the received image notification communication signal by the original image storage processing unit 2222 of the image storage processing unit 222b. , The automatically assigned original image file name is attached and stored in the original image storage unit 232. Then, the original image storage processing unit 2222 includes the original image file name, the camera ID accommodated in the received image notification communication signal, and the time accommodated in the received image notification communication signal as the imaging end time. Are linked to each other and stored in the original image storage unit 232 (C132).

Then, at the cutout timing, the management server device SVb cuts out the image according to the entry / exit of the worker NS from the original image by the image cutout storage processing unit 2221 of the image storage processing unit 222b. It is associated with the worker ID as the first specific information and stored in the image storage unit 231 (C141). More specifically, the image cutout storage processing unit 2221 has a set of worker IDs, camera IDs, which are temporarily stored in the SV storage unit 23b by the SV management processing unit 223 and are associated with each other. The start time and end time are extracted, and the original image file name associated with the extracted camera ID and including the extracted start time and end time is selected from the original image storage unit 232. Next, the image cutout storage processing unit 2221 cuts out an image of a portion corresponding to the extracted start time and end time from the original image having the selected original image file name, and generates a new image. Next, the image cutout storage processing unit 2221 automatically generates an image file name and an image ID for the cut out image, and attaches the cut out image to the generated image file name and stores the image. Store in unit 231. Then, the image cutout storage processing unit 2221 generates a new record in the image information table PT stored in the image storage unit 231, and the image ID field 2311 and the start time sub "field 23121, end" in the generated record. The generated image ID, the extracted start time, the extracted end time, the generated image file name, and the extracted work are displayed in the time subfield 23122, the image file name field 2313, and the worker ID field 2314, respectively. Each person ID is registered. Then, the image cutout storage processing unit 2221 deletes the registered start time, end time, and worker ID from the SV storage unit 23b together with the camera ID associated with them. The image cutout storage processing unit 2221 temporarily stores such processing in the SV storage unit 23b by the SV management processing unit 223, and the pair of worker IDs, camera IDs, and the camera IDs associated with each other are temporarily stored. Repeat until the start time and end time are basically gone (until they are all erased).

By such an operation, the image recording system MSb collects each original image from each of the imaging devices CUb-1 to CUb-3 arranged in each living room RM-1 to RM-3, and from each original image, each living room. Each image cut out according to the entry / exit of the worker NS with respect to RM-1 to RM-3 is generated, and the worker ID is associated with each of these images and stored (recorded).

Then, when extracting an image for the desired (objective) worker NS, for example, an operator such as the boss of the worker NS searches from the SV input unit 24, as in the image recording system MSa in the first embodiment. The worker ID corresponding to the desired worker NS is input as the key, the search start instruction is input, and the management server device SVb reproduces and displays the image on the SV output unit 25 accordingly. This allows the operator to refer to an image for the desired worker NS.

As described above, the image recording system MSb and the image recording method implemented in the image recording system MSb in the second embodiment are described when a predetermined worker NS enters the region to be imaged (in the present embodiment, the living room RM). One of the first and second specific information (camera ID as the second specific information in the present embodiment) is read and the other specific information (worker ID as the first specific information in the present embodiment) is read. By associating with the first and second specific information, the associative information in which the first and second specific information are associated with each other is generated, while the image and the second specific information thereof are obtained from the image pickup apparatus CUb. Then, the image recording system MSb and the image recording method obtain the image with the first specific information based on the second specific information received from the image pickup device CUb together with the image and the association information received from the mobile terminal device TAb. It is associated with and stored in the image storage unit 231. Therefore, the image recording system MSb and the image recording method can more easily extract an image for a desired (objective) worker NS by referring to the first specific information associated with the image. Therefore, the boss of the worker NS can grasp the dexterity, appropriateness, politeness, etc. of the work in the worker NS by referring to the image for the worker NS, and after grasping the actual situation of the worker NS. Then, the worker NS can be instructed.

Next, another embodiment will be described.

(Third Embodiment)
FIG. 14 is a diagram showing a configuration of an image pickup apparatus according to a third embodiment in the image recording system.

In the image recording systems MSa and MSb according to the first and second embodiments described above, the ID devices RDa and RDb and the mobile terminal devices TAa and TAb are brought close to each other so that the worker NS enters and exits the area to be imaged. However, in the image recording system MSc in the third embodiment, the sensor determines the entry / exit of the worker NS with respect to the region to be imaged. The image recording system MSc in such a third embodiment can be configured based on the image recording systems MSa and MSb in the first and second embodiments described above. Here, as an example, the image recording system MSc in the third embodiment configured based on the image recording system MSa in the first embodiment will be described below. Based on the image recording system MSb in the second embodiment, the image recording system MSc in the third embodiment can be configured in the same manner as follows.

The image recording system MSc in such a third embodiment is, for example, as shown in FIG. 1, one or a plurality of image pickup devices CUc (CUc-1 to CUc-3) similar to the image recording system MSa in the first embodiment. ), One or more ID devices RDc (RDc-1 to RDc-3), management server device SVc, one or more mobile terminal devices TAC (TAC-1, TAc-2), and private branch exchange CX. These are communicably connected via the network NW. The ID device RDc, the management server device SVc, the mobile terminal device TAc, and the private branch exchange CX in the image recording system MSc of the third embodiment are the ID device RDa and the management server device SVa in the image recording system MSa of the first embodiment, respectively. , The mobile terminal device TAa and the private branch exchange CX are the same, and the description thereof will be omitted.

Like the image pickup device CUa of the first embodiment, the image pickup device CUc is provided corresponding to the image pickup target, has a communication function for communicating with the management server device SVc via the network NW, and images the image pickup target. It is a device that generates an image. Then, in the present embodiment, the image pickup device CUc manages the entry / exit status of the worker NS with respect to the area to be imaged based on the detection result of the entry / exit detection unit 15 described later, and obtains the second specific information of the own machine in advance. It has and outputs (transmits) the generated image to the management server device SVc together with the second specific information of the own machine. As shown in FIG. 14, such an imaging device CUc includes, for example, a camera 11, a CU control processing unit 12c, a CU communication IF unit 13, a CU storage unit 14c, and an entrance / exit detection unit 15. The camera 11, CU communication IF unit 13 and CU storage unit 14c in the image pickup device CUc of the third embodiment are the camera 11, CU communication IF unit 13 and CU storage unit 14a in the image pickup device CUa of the first embodiment, respectively. Since it is the same, the description thereof will be omitted. Therefore, the CU storage unit 14c is functionally provided with the same CU entry / exit status information storage unit 141c as the CU entry / exit status information storage unit 141a.

The entry / exit detection unit 15 is connected to the CU control processing unit 12c, and detects the presence / absence of entry / exit in the area to be imaged according to the control of the CU control processing unit 12c. The entry / exit detection unit 15 outputs the detection result to the CU control processing unit 12c. The entrance / exit detection unit 15 is, for example, a plurality of light emitting units arranged so as to be juxtaposed at a predetermined height position along the entrance / exit direction at the boundary of the area to be imaged (for example, the entrance / exit of the living room RM). The unit and the plurality of light emitting units are separated from each other by a predetermined width (for example, a length equal to or larger than a person's width or the width of the entrance / exit of the living room RM) in an orthogonal direction orthogonal to the entrance / exit direction, and the plurality of units are separated from each other. A plurality of light receiving units arranged so as to receive each light emitted from each light emitting unit, and whether or not to enter or exit the region to be imaged is determined according to each light receiving result of each of the plurality of light receiving units. It is configured to include an entry / exit determination unit. In such a configuration, the entrance / exit determination unit determines that the entrance is entered when the light receiving outputs are sequentially obtained from the plurality of light receiving units along the entrance direction, and receives light sequentially from the plurality of light receiving units along the exit direction. When the output is obtained, it is judged to leave.

When only the entry of the worker NS to the area to be imaged is managed and the imaging is finished after a predetermined time has elapsed from the start of the imaging, the entrance / exit detection unit 15 may, for example, determine the boundary of the area to be imaged. An infrared motion sensor arranged in (for example, the entrance / exit of the living room RM or the like) and having the area to be imaged (for example, the living room RM or the like) as a detection area, and the infrared human sensor according to the detection result of the infrared motion sensor. It may be configured to include an admission determination unit that determines whether or not to enter the monitoring area.

Similar to the CU control processing unit 12a in the first embodiment, the CU control processing unit 12c controls each unit 11, 13, 14c of the image pickup apparatus CUc according to the function of each unit, and images the image pickup target. This is a circuit for generating an image and notifying the management server device SVc of the generated image. Then, the CU control processing unit 12c manages the entry / exit status of the worker NS with respect to the area to be imaged based on the detection result of the entry / exit detection unit 15, and when notifying the generated image to the management server device SVc. , The generated image is notified to the management server device SVc together with the second specific information (camera ID in this embodiment) of the own machine stored in advance in the CU storage unit 14c. The CU control processing unit 12c is configured to include, for example, a CPU and peripheral circuits thereof. The CU control processing unit 12c functionally includes the CU control unit 121, the generation unit 122c, and the image pickup control unit 123 by executing the CU control processing program. Since the CU control unit 121 and the image pickup control unit 123 in the CU control processing unit 12c of the third embodiment are the same as the CU control unit 121 and the image pickup control unit 123 in the CU control processing unit 12a of the first embodiment, respectively. , The description is omitted.

When the worker NS enters / exits (enters / exits) the area to be imaged (in the present embodiment, the living room RM), the generation unit 122c uses the ID device RDc to provide first specific information (worker ID in the present embodiment). When the entry / exit detection unit 15 detects entry / exit, the second specific information (camera ID in this embodiment) of the own machine and the first specific information read by the ID device RDc are linked to each other. The attachment information is generated, and the generated association information is output (transmitted) to the management server device SVc.

In the present embodiment, the generation unit 122c generates and transmits the association information with the image pickup side management processing unit (CU management processing unit) 1221c for managing the entry / exit status of the worker NS with respect to the area to be imaged. The notification processing unit 1222 of the above is functionally provided. Since the notification processing unit 1222 in the generation unit 122c of the third embodiment is the same as the notification processing unit 1222 in the generation unit 122c of the first embodiment, the description thereof will be omitted.

The CU management processing unit 1221c manages the first specific information (worker ID in the present embodiment) read by the ID device RDc based on the detection result of the entry / exit detection unit 15. More specifically, when the CU management processing unit 1221c is read by the ID device RDc and the worker ID is notified from the ID device RDc, and when the entry / exit detection unit 15 detects entry, If the notified worker ID is not registered in the worker ID field 1411 (see FIG. 16 described later) of the CU entry / exit status information table MTc stored in the CU entry / exit status information storage unit 141c, a new worker ID is newly registered. Record is generated, and the notified worker ID is registered in the worker ID field 1411 of the newly generated record. On the other hand, the CU management processing unit 1221c is notified when the ID device RDc reads it and the ID device RDc notifies the worker ID, and when the entry / exit detection unit 15 detects the exit. When the worker ID is registered in the worker ID field 1411 of the CU entry / exit status information table MTc stored in the CU entry / exit status information storage unit 141c, the record for registering the notified worker ID is recorded. delete. In this way, the CU management processing unit 1221c manages the entry / exit status of the worker NS with respect to the area to be imaged, depending on whether or not the worker ID is stored.

When the entry / exit detection unit 15 detects only entry, the ID device RDc and the mobile terminal device TAC are close to each other, and when the ID device RDc notifies the worker ID, the CU management processing unit 1221c If the notified worker ID is registered in the worker ID field 1411 of the CU entry / exit status information table MTc stored in the CU entry / exit status information storage unit 141c, the notified work The record for registering the person ID may be deleted.

Next, the operation of this embodiment will be described.

In the image recording system MSc having the above configuration, when the power is turned on, each device CUc, RDc, SVc, and TAC executes necessary initialization of each part and starts its operation. In the image pickup apparatus CUc, the CU control processing unit 12c is functionally configured with the CU control unit 121, the generation unit 122c, and the imaging control unit 123 by executing the CU control processing program, and the generation unit 122c is CU-managed. The processing unit 1221c and the notification processing unit 1222 are functionally configured. The management server device SVc and the mobile terminal device TAC are the same as those in the first embodiment.

Then, the image recording system MSc collects each image from each image pickup apparatus CUc-1 to CUc-3 by the operation of the third embodiment regarding image recording as follows, and records each image. Here, in the following description, as an example, at the beginning, the worker ID; "ID-NA" is input to the mobile terminal device TAC-1 carried by the worker NS-1 at the time of, for example, a login operation. The worker ID; "ID-NA" is stored in advance, and the worker ID; "ID-NB" is stored in the mobile terminal device TAC-2 carried by the worker NS-2, for example, when a login operation is performed. Is input, and it is assumed that the worker ID; "ID-NB" is stored in advance. Then, as shown on the left side of the paper in FIG. 16, the CU entry / exit status information table MTc-t31, in which the worker NS is not present in the living room RM-1 and is stored in the CU entry / exit status information storage unit 141c. , It is assumed that the worker ID is not registered (memorized).

In FIG. 15, the worker NS-1 carries a mobile phone when entering the room RM-1 of the monitored person Ob-1 in order to perform a predetermined work such as nursing, nursing care, or cleaning. The terminal device TAc-1 is brought close to the ID device RDc-1 provided corresponding to the living room RM-1, and a reading operation for reading the worker ID is performed (C211).

When the mobile terminal device TAC-1 and the ID device RDc-1 are close to each other, the mobile terminal device TAC-1 has its stored worker ID; "ID-NA", as in the above-described processing C12. Is transmitted by the TAIF unit 37, and the ID device RDc-1 receives the worker ID; “ID-NA” transmitted from the mobile terminal device TAc-1, thereby the worker ID; “ID-NA”. Is read from the mobile terminal device TAC-1 (C212).

Subsequently, the ID device RDc-1 obtains the worker ID; “ID-NA” read from the mobile terminal device TAC-1 in the same manner as the above-described processing C13, by the imaging device CUc provided in the living room RM-1. Notify -1 (C213).

Here, the worker NS-1 brought the mobile terminal device TAc-1 and the ID device RDc-1 close to each other as described above, but entered (entered) the living room RM-1 by, for example, a sudden call. ) Without leaving the living room RM-1, the entrance / exit detection unit 15 does not detect the entrance of the worker NS-1, and the entrance / exit detection unit 15 outputs the entry detection result to the CU control processing unit 12c. Not done. Therefore, the image pickup apparatus CUc-1 does not perform the subsequent processing. Therefore, in the example shown in FIG. 16, even if the ID device RDc-1 notifies the worker ID; “ID-NA”, the CU entry / exit status information table MTc-t31 shown on the left side of the paper in FIG. 16 is shown in FIG. Like the CU entry / exit status information table MTc-t32 shown second from the left on the 16th page, the CU entry / exit status information storage unit 141c has the SU entry / exit status information table MTc-t32 without the registration of the worker ID. It is stored (MTc-t31 = MTc-t32). Therefore, imaging by the imaging device CUc-1 is not started. The image pickup device CUc enters or exits from the entry / exit detection unit 15 within a predetermined time set in advance (for example, within 5 seconds or within 10 seconds) after the worker ID is notified from the ID device RDc. This process may be terminated when the detection result of is not notified.

There, for example, in order to perform a predetermined work, when the worker NS-2 enters the living room RM-1 of the monitored person Ob-1, the portable terminal device TAc-2 carried by the worker NS-2 is described above. A reading operation is performed in which the worker ID is read by approaching the ID device RDc-1 provided corresponding to the living room RM-1 (C221).

When the mobile terminal device TAC-2 and the ID device RDc-1 are in close proximity to each other, the mobile terminal device TAC-2 has its stored worker ID; "ID-NB" in the same manner as the above-mentioned processing C12. Is transmitted by the TAIF unit 37, and the ID device RDc-1 receives the worker ID; “ID-NB” transmitted from the mobile terminal device TAc-2, thereby the worker ID; “ID-NB”. Is read from the mobile terminal device TAc-2 (C222).

Subsequently, the ID device RDc-1 obtains the worker ID; "ID-NB" read from the mobile terminal device TAC-2 in the same manner as the above-described processing C13, by the imaging device CUc provided in the living room RM-1. Notify -1 (C223).

When the worker NS-2 enters the living room RM-1, the entry / exit detection unit 15 detects the entry of the worker NS-2 and outputs the entry detection result to the CU control processing unit 112c (C224).

Upon receiving the notification of the worker ID; "ID-NB" from the ID device RDc-1 and the entry detection result from the entry / exit detection unit 15, the image pickup device CUc-1 performs the work on the living room RM-1. In order to process the entry / exit status of the person NS, the CU management processing unit 1221c of the generation unit 122c in the CU control processing unit 12c manages the worker ID; "ID-NB" notified from the ID device RDc-1 ( C225). More specifically, this notified worker ID; "ID-NB" is not registered in the worker ID field 1411 of the CU entry / exit status information table MTc stored in the CU entry / exit status information storage unit 141c. In this case, the CU management processing unit 1221c generates a new record and registers the notified worker ID; "ID-NB" in the worker ID field 1411 of the newly generated record. On the other hand, when the notified worker ID; "ID-NB" is registered in the worker ID field 1411 of the CU entry / exit status information table MTc stored in the CU entry / exit status information storage unit 141c, The CU management processing unit 1221c deletes the record for registering the notified worker ID; "ID-NB".

In the example shown in FIG. 16, when the worker ID; "ID-NB" is notified from the ID device RDc-1 and the entry detection result is received from the entry / exit detection unit 15, the notified worker ID is received. Since "ID-NB" is not registered in the worker ID field 1411 of the CU entry / exit status information table MTc-t32 stored in the CU entry / exit status information storage unit 14c, the CU management processing unit 1221c is new. A record is generated, and the notified worker ID; "ID-NB" is registered in the worker ID field 1411 of the newly generated record. As a result, the CU entry / exit status information table MTc-t32 shown second from the left on the paper surface of FIG. Person ID: The CU entry / exit status information table MTc-t33 in which "ID-NB" is registered is stored.

Subsequently, since the worker ID; "ID-NB" is present in the CU entry / exit status information table MTc-t33 managed by the CU management processing unit 1221c, the imaging device CUc-1 can start imaging. The image pickup control unit 123 outputs an instruction to start image pickup to the camera 11 (C226). When the camera 11 receives an instruction to start imaging from the imaging control unit 123, the camera 11 starts imaging, outputs an image generated by this imaging to the CU control processing unit 12c, and the CU control processing unit 12c outputs this image to the CU control processing unit 12c. It is temporarily stored in the storage unit 14c. As a result, an image (moving image in the present embodiment) of the imaged object is generated and stored in the CU storage unit 14c.

Subsequently, since the worker ID is newly registered in the process C225, the image pickup device CUc-1 notifies the generation unit 122c in the CU control processing unit 12c in order to notify the association information, as in the above-mentioned process C16. The processing unit 1222 generates linking information in which the camera ID of the own machine; "CU-1" and the worker ID; "ID-NB" read and notified by the ID device RDc-1 are linked to each other. The generated association information and the current time as the imaging start time are notified to the management server device SVc (C227).

Upon receiving the notification of the association information and the imaging start time from the imaging device CUc-1, the management server device SVc temporarily transmits the association information and the imaging start time to the SV storage unit 23a in the same manner as the above-described processing C17. Temporarily memorize (C228).

Then, upon completion of the work, the worker NS-2 present in the living room RM-1 transfers the portable terminal device TAC-2 carried by the worker NS-2 to the living room RM-1 when leaving the room. A reading operation is performed in which the worker ID; "ID-NB" is read in close proximity to the corresponding ID device RDc-1 (C231).

When the mobile terminal device TAC-2 and the ID device RDc-1 are in close proximity to each other, the mobile terminal device TAC-2 has its stored worker ID; "ID-NB" in the same manner as the above-mentioned processing C12. Is transmitted by the TAIF unit 37, and the ID device RDc-1 receives the worker ID; “ID-NB” transmitted from the mobile terminal device TAc-2, thereby the worker ID; “ID-NB”. Is read from the mobile terminal device TAc-2 (C232).

Subsequently, the ID device RDc-1 obtains the worker ID; "ID-NB" read from the mobile terminal device TAC-2 in the same manner as the above-described processing C13, by the imaging device CUc provided in the living room RM-1. Notify -1 (C233).

When the worker NS-2 leaves the living room RM-1, the entry / exit detection unit 15 detects the exit of the worker NS-2 and outputs the exit detection result to the CU control processing unit 112c (C234).

Upon receiving the notification of the worker ID; "ID-NB" from the ID device RDc-1 and the exit detection result from the entry / exit detection unit 15, the image pickup device CUc-1 performs the work on the living room RM-1. In order to process the entry / exit status of the person NS, the CU management processing unit 1221c of the generation unit 122c in the CU control processing unit 12c manages the worker ID; "ID-NB" notified from the ID device RDc-1 ( C235). More specifically, here, as shown second from the right on the page of FIG. 16, the notified worker ID; "ID-NB" is stored in the CU entry / exit status information storage unit 141c. Since it is registered in the worker ID field 1411 of the entry / exit status information table MTc-t33, the CU management processing unit 1221c deletes the record for registering the notified worker ID; "ID-NB". As a result, the CU entry / exit status information table MTc-t33 shown on the right side of the paper in FIG. 16 becomes the CU entry / exit status information table MTc-t34 shown on the right side of the paper, and the worker ID; The record in which "ID-NB" is registered disappears, and the CU entry / exit status information table MTc-t34 in which no worker ID is registered is stored.

Subsequently, since there is no worker ID in the CU entry / exit status information table MTc-t34 managed by the CU management processing unit 1221c, the imaging device CUc-1 ends the imaging in the same manner as the above-mentioned processing C25. In addition, the image pickup control unit 123 outputs an instruction to end the image pickup to the camera 11 (C236). When the camera 11 receives the instruction to end the imaging from the imaging control unit 123, the camera 11 ends the imaging.

When the imaging is completed, the imaging device CUc-1 transmits the image temporarily stored in the CU storage unit 14c to the management server device SVc by the CU control processing unit 12c (C237). More specifically, the CU control processing unit 12c stores the image temporarily stored in the CU storage unit 14c, the camera ID of the own machine, and the image notification communication signal accommodating the current time as the imaging end time. Send to the management server device SVc.

Upon receiving the notification of the image from the image pickup device CUc-1, the management server device SVc links the image from the image pickup device CUc-1 to the worker ID as the first specific information in the same manner as the above-mentioned processing C27. It is attached and stored in the image storage unit 231 (C238).

By such an operation, the image recording system MSc collects each image from each imaging device CUc-1 to CUc-3 arranged in each living room RM-1 to RM-3, and associates a worker ID with each image. Attach and memorize (record).

Then, when extracting an image for the desired (objective) worker NS, for example, an operator such as the boss of the worker NS searches from the SV input unit 24, as in the image recording system MSa in the first embodiment. The worker ID corresponding to the desired worker NS is input as the key, the search start instruction is input, and the management server device SVc reproduces and displays the image on the SV output unit 25 accordingly. This allows the operator to refer to an image for the desired worker NS.

As described above, the image recording system MSc in the third embodiment and the image recording method implemented therein have the same effects as those in the first embodiment (when the second embodiment is used as a base, the image recording system has the same effects as those in the first embodiment. It has the same effect as that of the second embodiment).

Although the area to be imaged has been reached, the worker NS has the ID device RDc as the first specific information (work in the above description) as the one specific information because it is necessary to go to another place due to a change in the situation. Although the person ID) is read, it may not be possible to enter the area to be imaged. The image recording system MSc and the image recording method further include an entry / exit detection unit 15, and when the entry / exit detection unit 15 detects the presence of entry, the linked information is output to the management server device SVc. Therefore, when the worker NS causes the ID device RDc to read the specific information of the one, but does not enter the area to be imaged, the linked information is not output to the management server device SVc. Therefore, in the image recording system MSc and the image recording method, the first specific information (worker ID in the above description) is more appropriately associated with the image from the image pickup apparatus CUc unit.

Further, as described above, the worker NS may have the ID device RDc read the specific information of the one, but may not enter the area to be imaged. On the other hand, considering that the predetermined work has been completed, the worker NS may have the ID device RDc read the specific information of the one, but may notice the unfinished work and do not leave the area to be imaged. It is possible. The image recording system MSc and the image recording method further include an entrance / exit detection unit 15, and when the entrance / exit detection unit 15 detects the presence of entry, the image recording start instruction is output to the camera 11 to output the entry / exit detection unit. When it is detected that there is an exit at 15, the instruction to end the imaging is output to the camera 11. Therefore, when the worker NS causes the ID device RDc to read the specific information of one of the above, but does not enter or leave the area to be imaged, the instruction to start the imaging and the instruction to end the imaging are given. Absent. Therefore, the image recording system MSc and the image recording method can more appropriately store (record) an image according to the entrance and exit of the worker.

Next, another embodiment will be described.

The SU storage unit 46 functionally includes a sensor-side entry / exit status information storage unit (SU entry / exit status information storage unit) 461 that stores the SU entry / exit status information. Since the SU entry / exit status information storage unit 461 is the same as the CU entry / exit status information storage unit 141a of the first embodiment, the description thereof will be omitted.

The SU control processing unit 44 controls each unit 41 to 43, 45, 46 of the sensor device SU according to the function of each unit, and sends a predetermined event (event) related to the monitored person Ob to the management server device SVd. It is a circuit for notifying. More specifically, in the present embodiment, the SU control processing unit 44 detects a predetermined action in the monitored person Ob and notifies the management server device SVd of the detection result as an example of the predetermined event (notification, (Send), accept the nurse call, notify (notify, transmit) the nurse call to the management server device SVd as another example of the predetermined event, make a voice call with the mobile terminal device TAd, and make a video. An image including the image is generated and the moving image is distributed to the mobile terminal device TAd. Then, in the fourth embodiment, the SU control processing unit 44 further functions in the same manner as the CU control processing unit 12a of the first embodiment. The SU control processing unit 44 includes, for example, a CPU and peripheral circuits thereof. When the SU control processing program is executed, the SU control processing unit 44 has a sensor side control unit (SU control unit) 441, a generation unit 442, an imaging control unit 443, an action detection processing unit 444, and a nurse call processing unit 445. And the sensor side streaming processing unit (SU streaming processing unit) 446 are functionally provided, and the generation unit 442 is functionally provided with the SU management processing unit 4421 and the notification processing unit 4422. The generation unit 442 and the image pickup control unit 443 are respectively. Since it is the same as the generation unit 122a and the imaging control unit 123 in the first embodiment, and the SU management processing unit 4421 and the notification processing unit 4422 are the same as the CU management processing unit 1221a and the notification processing unit 1222 in the first embodiment. , The description is omitted.

The action detection processing unit 444 detects a predetermined action set in advance in the monitored person Ob and notifies the management server device SVd of the detection result as an example of the predetermined event. More specifically, in the present embodiment, the predetermined actions include, for example, waking up when the monitored person Ob wakes up, getting out of bed when the monitored person Ob leaves the bedding, and falling when the monitored person Ob falls from the bedding. And, there are four actions of a fall in which the monitored person Ob has fallen. Then, the behavior detection processing unit 444 detects the head of the monitored person Ob based on the image (target image) captured by the camera 11, for example, and the time of the size of the detected head of the monitored person Ob. Detects getting up, getting out of bed, falling, and falling of the monitored person Ob based on the change. More specifically, first, the location area of the bedding BD and the first to third threshold values Th1 to Th3 are stored in advance in the SU storage unit 46 as one of the various predetermined data. The first threshold value Th1 is a threshold value for discriminating between the size of the head in the lying posture and the size of the head in the sitting posture in the region where the bedding BD is located. The second threshold value Th2 is a threshold value for discriminating whether or not the size of the head in the standing posture in the living room RM excluding the area where the bedding BD is located. The third threshold value Th3 is a threshold value for discriminating whether or not the size of the head in the lying posture in the living room RM excluding the area where the bedding BD is located. Then, the behavior detection processing unit 444 first extracts a moving object region from the target image as a region of the person of the monitored person Ob by, for example, the background subtraction method or the frame subtraction method. Next, the behavior detection processing unit 444 uses the extracted moving body region, for example, by a circular or elliptical Hough transform, by, for example, by pattern matching using a prepared head model, or, for example, for head detection. The head region of the monitored person Ob is extracted by the neural network learned in. Then, the behavior detection processing unit 444 detects getting up, getting out of bed, falling, and falling from the extracted position and size of the head. For example, in the behavior detection processing unit 444, the position of the extracted head is within the location region of the bedding BD, and the size of the extracted head is the size of the lying posture by using the first threshold Th1. When the size of the sitting posture changes from the time to the sitting posture, it is determined that the person has woken up, and the wake-up is detected. For example, in the behavior detection processing unit 444, when the position of the extracted head changes from the inside of the location area of the bedding BD to the outside of the location area of the bedding, the size of the extracted head is the second size. When the time changes from a certain size to the size of the standing posture by using the threshold value Th2, it is determined that the person has left the bed, and the person has left the bed. For example, in the behavior detection processing unit 444, when the position of the extracted head changes from the inside of the location area of the bedding BD to the outside of the location area of the bedding BD, the size of the extracted head is the first. When the time changes from a certain size to the size of the lying posture by using the three threshold value Th3, it is determined that the person has fallen, and the fall is detected. For example, in the behavior detection processing unit 444, the position of the extracted head is in the living room RM excluding the area where the bedding BD is located, and the size of the extracted head uses the third threshold value Th3. When the time changes from the size of the head to the size of the lying posture, it is determined that the person has fallen, and the fall is detected.

When the predetermined action is detected in this way, the action detection processing unit 444 notifies the event, which contains event information (event information) representing the content of the predetermined event (event) related to the monitored person Ob. The communication signal (first event notification communication signal) of the above is notified to the management server device SVd by the SU communication IF unit 45. More specifically, the action detection processing unit 444 sends the camera ID of the own machine, the event information representing the content of the event, and the first event notification communication signal containing the target image used for detecting the predetermined action to the SU. It is transmitted to the management server device SVd via the communication IF unit 45. The event information is represented by the type of event, and in the present embodiment, it is one or more of getting up, getting out of bed, falling, falling and nurse call (NC), and here, the action detection processing unit 142 detects. One or more of the wake-up, wake-up, fall, and fall are accommodated in the first event notification communication signal as the event information. The image may be at least one of a still image and a moving image. In the present embodiment, the still image is first notified, and the moving image is distributed according to the request of the operator.

When the nurse call reception operation unit 43 receives the nurse call, the nurse call processing unit 445 notifies the management server device SVd of the first event notification communication signal accommodating the fact as another example of the predetermined event. By using the SU sound input / output unit 42 and the like, a voice call is made with the mobile terminal device TAd. More specifically, when the nurse call reception operation unit 43 is input-operated, the nurse call processing unit 445 performs SU communication with the camera ID of its own machine and the first event notification communication signal accommodating the nurse call as the event information. It is transmitted to the management server device SVd via the IF unit 45. Then, the nurse call processing unit 445 uses the SU sound input / output unit 42 and the like to make a voice call with the mobile terminal device TAd, for example, by VoIP (VoIP over Internet Protocol).

When the mobile terminal device TAd requests the distribution of a moving image from the mobile terminal device TAd via the SU communication IF unit 46, the SU streaming processing unit 446 sends the moving image generated by the camera 11 to the requested mobile terminal device TAd (for example,). (Live video) is delivered by streaming playback via the SU communication IF unit 45.

Upon receiving the notification of the image from the sensor device SU (when the image notification communication signal is received from the sensor device SU), the management server device SVd receives the image storage processing unit 222d of the SV control processing unit 22d from the sensor device SU. The image is stored in the image storage unit 231a in association with the worker ID as the first specific information and the event detected most recently by the sensor device SU (C27).

More specifically, the image storage processing unit 222d stores the image accommodated in the received image notification communication signal in the image storage unit 231d with an image file name. Next, the image storage processing unit 222d matches the camera ID accommodated in the received image notification communication signal from the camera IDs of the associated information temporarily stored in the SV storage unit 23d. The camera ID to be used is selected (searched), the worker ID and the imaging start time in the association information having the selected camera ID, and the image (the image file name) accommodated in the received image notification communication signal. And the imaging end time are associated with each other. Next, the image storage processing unit 222d assigns a serial number as an image ID to the pair of associated worker IDs, the imaging start time, the image file name, and the imaging end time. Next, the image storage processing unit 222d converts the camera ID accommodated in the received image notification communication signal into a room name (when the camera ID is a room name, this conversion processing can be omitted), and the image storage unit From the image information table IT with detection event stored in 231d, the same room name (camera ID) as the room name (that is, the camera ID accommodated in the received image notification communication signal) converted as necessary is obtained. , The record registered in the room name field 2317 and registered in the event detection time field 2315 at the time closest to the imaging end time accommodated in the received image notification communication signal is selected (searched). The event information registered in the event type field 2316 in the selected record is extracted, and the extracted event information is used as the associated set of the worker ID, the imaging start time, the image file name, and the above. Further link to the imaging end time. Then, the image storage processing unit 222d generates a new record in the image information table IT with a detection event stored in the image storage unit 231d, and the image ID field 2311, the event type field 2316, and the start time in the generated record. The image ID, the extracted event information, and the imaging start time (accommodated in the association information notification communication signal) are stored in the sub-field 23121, the end time sub-field 23122, the image file name field 2313, and the worker ID field 2314, respectively. Time), the imaging end time (time accommodated in the image notification communication signal), the image file name, and the worker ID are registered. Then, the image storage processing unit 222d erases (deletes) the association information and the imaging start time temporarily stored in the SV storage unit 23d. The room name may be registered in the room name field 2317 in this new record.

In the above description, only the latest event information is linked, but all the first event notification communications received within a predetermined time (for example, within 5 minutes or within 10 minutes) from the received image notification communication signal. The event information contained in the signal may be linked.

By such an operation, the monitored person monitoring support system MSd collects each image from each sensor device SU-1 to SU-3 arranged in each living room RM-1 to RM-3, and the operator in each image. The ID and the event are linked and stored (recorded).

When the management server device SVd receives the worker ID of the search key and the instruction to start the search, the worker ID of the search key is selected from the images stored in the image storage unit 231d by the SV control processing unit 22d. The image with is searched and output to the SV output unit 25. More specifically, when the worker ID of the search key; "ID-NA" is received, the SV control processing unit 22d receives the worker ID field of the image information table IT with a detection event stored in the image storage unit 231d. A record for registering the received worker ID; "ID-NA" is extracted in 2314, and registered in the fields 2311, 2315, 2316, 2312 (2311, 23122), 2313, 2317, 2314 in the extracted record. Image ID, event detection time, event information, recording time (imaging start time, imaging end time), image file name, room name and worker ID are extracted, and the extracted image ID, event detection time, event information , The recording time (imaging start time, imaging end time), image file name, room name, and worker ID are displayed on the SV output unit 25 in a list format, for example, as shown in FIG. The extraction result display screen 62a of the example shown in FIG. 26 has an image ID display field 621 for displaying the extracted image ID, an event detection time display field 622 for displaying the extracted event detection time, and the extracted event. The event type display field 623 for displaying information, the recording time display field 624 for displaying the extracted recording time, the image file name display field 625 for displaying the extracted image file name, and the extracted room name are displayed. The room name display field 626 and the worker ID display field 627 for displaying the extracted worker ID are provided, and the number of display lines corresponding to the number of the extracted records is provided. The recording time display field 624 includes a start time display field 6241 and an end time display field 6242 that display the taken-out imaging start time and imaging end time, respectively. Then, when the image file name displayed in the image file name display field 625 is input from the SV input unit 24 (for example, when the cursor is moved to the image file name with the mouse and left-clicked), the SV control processing unit 22d inputs this input. An image having the manipulated image file name is taken out from the image storage unit 231d, and the taken out image is reproduced and displayed on the SV output unit 25. This allows the operator to refer to an image for the desired worker NS.

Then, in the fourth embodiment, since the image is also associated with the event information, it is possible to search by the event type. In this case, the operator inputs the desired event information (in this embodiment, one or more of wake-up, getting out, falling, falling, and nurse call) as a search key from the SV input unit 24, and starts the search. Enter the instructions.

When the management server device SVd receives the event information of the search key and the instruction to start the search, the SV control processing unit 22d has the event information of the search key from each image stored in the image storage unit 231d. The image is searched and output to the SV output unit 25. More specifically, when the event information of the search key; "fall" is received, the SV control processing unit 22d enters the event type field 2316 of the image information table IT with a detection event stored in the image storage unit 231d. Received event information: A record for registering "fall" is extracted, and image IDs and events registered in the fields 2311, 2315, 2316, 2312 (2311, 23122), 2313, 2317, 2314 in the extracted record.
