Specifically, when a family ID and password are input from the input unit of the home PC 4 and the personal authentication is normally performed with the ID and password, the PC 2 can display a live image if it is a viewing request for the current image. The data is transmitted to the home PC 4, and if it is a browsing request for a past image of a specific period, the past image data of the specific period is read from the HDD 23 and transmitted to the home PC 4, and the home PC 4 receives the image data and displays it on the display unit. indicate.

  The home PC 5 is a computer installed in the home of a cared person who receives care at home, and is equipped with a PC, a display unit, a conversation camera, a camera for indoor use, a microphone, a mat, and the like as in the room. The same processing as that of the indoor PC 2 is performed.

Next, processing operations with the server 1 and the PC 2 connected thereto will be described.
In the PC 2, the room is always photographed by the indoor photographing camera 27 and the photographed image data is stored in the HDD 23. When image data is stored in the HDD 23, it is better to perform data encryption and data compression.
Here, the image data stored in the HDD 23 may be moving image data, but may be still image data in order to save storage capacity. For example, it is possible to store image data of four still images per second.

  When an instruction to select the indoor shooting camera 27 is input from the input unit of the server 1, the control unit 11 of the server 1 captures a live (current) image captured by the indoor shooting camera 27 with respect to the PC 2. Requests transmission of data or past image data.

When the PC 2 receives a transmission request for past image data from the server 1, the PC 1 designates a past specific period (reproduction start date / time to reproduction end date / time). Is read from the HDD 23 and transmitted to the server 1 via the LAN.
The server 1 performs processing such as decryption and decompression on the received data and displays the data on the display unit 15.
Therefore, the image data stored in the HDD 23 of the PC 2 can be reproduced and viewed by remote control according to an instruction from the input unit of the server 1.

Further, when the PC 2 receives a transmission request for the current image data (live image data) from the server 1, the PC 2 compresses and encrypts the image shot by the indoor shooting camera 27 and stores it in the HDD 23. To the server 1.
The server 1 performs processing such as decryption and decompression on the received data and displays the data on the display unit 15.
Since the audio data is also stored in the HDD 23 in synchronization with the image data, the audio data is also transmitted from the PC 2 to the server 1 and reproduced by the server 1 and output as audio.

  Here, the difference between the reproduction of the past image data and the reproduction of the live image data in the server 1 will be described. If any change occurs in the cared person, the past image of the cared person up to that point is displayed. The image is played back to check the situation, but the live image only needs to check whether the cared person is living (moving) normally. It is not preferable for the caregiver to browse from the viewpoint of privacy. Of course, if the care recipient permits, it is possible to reproduce the live image with a normal quality image.

Therefore, a live image is generated by editing a mosaic image or an image of a dynamic sensing shot (an image in which a fluctuating point is drawn in the captured image) with the PC 2, and the edited live image data is transmitted to the server 1. .
By doing so, the care recipient's privacy is protected, and the amount of data to be transmitted can be reduced compared to normal image data transmission.

Next, a method for realizing a dialogue between a caregiver and a care recipient will be described.
When the caregiver thinks that it is necessary to have a conversation with the care receiver while referring to the indoor image of the care receiver of the display unit 15 connected to the server 1, the dialog screen is displayed by starting the interactive software. The display unit 15 displays the call, calls the other care recipient, connects the line, and starts a conversation.
In the PC 2 of the other care recipient, the call from the server 1 is received and notified to the care recipient by display or sound or both, and the care recipient responds on the screen of the display unit 25, so that the caregiver's face An image is displayed and the conversation starts.

  In addition, when the care recipient wants to talk to the caregiver, the PC 2 starts the dialogue software, displays the dialogue screen on the display unit 25, calls the other caregiver, connects the line, and starts the conversation. . In the caregiver's server 1, the call from the PC 2 is received and notified to the caregiver by display or sound or both, and the caregiver responds on the display screen of the display unit 15, whereby the face image of the cared person is displayed. And the conversation starts.

Moreover, not only the request | requirement of the independent conversation start by a caregiver or a care receiver but a conversation may be automatically started when a specific condition is satisfied as described below.
Specifically, the heart rate detected by the mat 28 installed in the cared person's room is output to the PC 2, and the detected heart rate by the PC 2 is within an appropriate range stored in the HDD 23 in advance. Is determined by the control unit 21 of the PC 2, and if it is out of the proper range, an alarm is output to the display unit 15 and the speaker of the server 1 via the LAN to make a call. When the caregiver responds on the screen of the display unit 15 of the server 1, a dialog screen is displayed on the display unit 15, and a dialog screen is also displayed on the display unit 25 even on the PC 2 to enable a forced dialog.
If the heart rate is outside the appropriate range, the server 1 and the PC 2 may immediately start the interactive software and call both the server 1 and the PC 2.

A display example of the display unit 15 connected to the server 1 will be described with reference to FIG. FIG. 2 is an explanatory diagram showing an overview of a display screen in the display unit 15 of the present system.
As shown in FIG. 2, the names (room numbers, etc.) of the rooms and the other rooms (entertainment room, esophagus, lobby, etc.) in which the indoor shooting camera 27 is installed are displayed on the lower side of the screen of the display unit 15. The number of each room can be selected with a mouse or the like.
A second display section 32, a third display section 33, a fourth display section 34, and a fifth display section 35 are arranged thereon, and a captured image of the room is displayed together with the name of the selected room. The

A log display unit 36 for displaying the access log of the server 1 is arranged at the upper right of the screen, and a first display unit 31 for selecting a display image is arranged at the upper left of the screen.
On the first display unit 31, the name of the room to be displayed selected is displayed on the upper right, and four camera (CAMERA1 to 4) buttons 40 and an OFF button to be selected are displayed below the first display unit 31.

The OFF button is a button for turning off the camera, and the camera button 40 selects one of the second to fifth display units 32 to 35 and selects an image to be displayed on the first display unit 31. Button. The camera button 40 is easy to see if only the selected button changes color.
Specifically, for example, when the camera 1 is selected with the camera button 40 and a room name such as room 102 is selected from the name display portion of each room, a captured image of the room is displayed on the second display unit 32. And displayed on the first display unit 31.
Here, when the camera 2 is selected with the camera button 40, an image of the entertainment room already selected on the third display unit 33 is displayed on the first display unit 31.

In addition, operation buttons such as “stop”, “play”, “rewind”, “fast forward”, “live broadcast (Live)”, and “set” are installed below the first display unit 31, and these buttons are used for a mouse or the like. When the button is clicked and pressed, processing such as reproduction of an image recorded in the HDD 23 of the PC 2 is performed.
However, in the case of live relay, the image data input to the HDD 23 is branched and transmitted and received and displayed. The transmitted image data may be image data that has been subjected to mosaic processing or dynamic sensing shot processing.

Further, the video time is displayed between the first display unit 31 and the log display unit 36, and the reproduction time of the image displayed on the first display unit 31 in the first row is displayed. The second row shows how much the playback time is past the current time. For example, when “20:12:15” is displayed in the first row and “−12: 37: 05” is displayed in the second row, the image displayed on the first display unit 31. Means 12 hours 37 minutes 05 seconds (previous day) at 20 hours 12 minutes 15 seconds.
Although not shown in FIG. 2, the current time provided by the OS is generally displayed at the lower right of the display unit 15.

Next, processing of the control unit 11 of the server 1 in this system will be described with reference to FIG. FIG. 3 is a flowchart showing processing in the control unit of the server.
As shown in FIG. 3, the control unit 11 of the server 1 selects a camera number with the camera button 40 (S11) and then selects a room number (name of the room) as shown in the display screen of FIG. (S12), it is determined whether or not the operation button is "live relay" (S13).

If the live relay is set in step S12 (Yes), the control unit 11 requests the PC 2 to transmit a LIVE video and displays the received LIVE video (current image) (S14).
If the live relay is not set in step S12 (in the case of No), the control unit 11 transmits an instruction to select a past specific time to the PC 2 (S15), and the HDD 23 of the PC 2 corresponds to the instruction. The image data recorded in the above is received from the PC 2 and reproduced and displayed (S16).

  Then, in the server 1, it is determined whether or not the stop button on the screen is pressed (S17). If the stop button is not pressed (No), the display of the image data is continued, and the stop button is pressed. If yes (in the case of Yes), the process is terminated.

Further, a forced call start process based on the heart rate of the care receiver in the PC 2 will be described with reference to FIG. FIG. 4 is a flowchart showing a process flow of forced call start in the PC 2.
As shown in FIG. 4, the control unit 21 of the PC 2 determines whether or not the heart rate data input from the mat 28 is out of the appropriate range set in advance as the appropriate value of the care recipient (S1). If it is not out-of-range heart rate data (in the case of No), the determination process S1 is repeated.

If the heart rate data is outside the proper range (in the case of Yes), the server 1 of the management center is notified (S2), and the heart rate data outside the proper range is transmitted to the server 1 (S3).
Further, the control unit 21 of the PC 2 secures a communication line and an image line with the server 1 (S4) so that a care recipient of the PC 2 and a caregiver of the server 1 can start a dialogue. At this time, the display unit 25 and the conversation person photographing camera 26 may be automatically turned on to prepare for the conversation.

  According to this system, image data obtained by photographing the situation of the cared person is accumulated in the HDD 23 of the PC 2 installed in the room of the cared person, and the image data accumulated only when requested by the server 1 and Since the live image data is transmitted, it is possible to save the trouble of managing large-capacity image data in the server 1, further reduce the occupation rate in the line between the PC 2 and the server 1, and further improve the care recipient's This has the effect of ensuring the security of the shooting data.

  Further, according to the present system, the capacity of the HDD 23 can be saved if the image data stored in the HDD 23 of the PC 2 is data of a still image obtained by shooting a specific number of images within a specific time. Further, it is effective to compress and encrypt the still image data.

  Further, according to the present system, if the live image data transmitted from the PC 2 to the server 1 is a mosaic image or an image of a dynamic sensing shot, the care recipient's privacy can be protected and the amount of transmitted data can be reduced. Can be reduced.

In this system, care facilities such as nursing homes are assumed. However, as a system composed mainly of home care, the management center server 1 in FIG. 1 and one or a plurality of home PCs 5 are used. Also good.
Further, the present system may be applied to a facility such as a hospital, and the PC 2 may be installed in a hospital room or the like.
