The detection information is received by the control device 12 by wire or wirelessly. Then, when the detection information is received by the control device 12, in response to the detection information being passed through the gate 13, or
The image of the child 14 approaching the gate 13 is picked up by the image pickup device 10, and the picked-up image is recorded in the recording device in the control device 12, for example. By doing so, for example, it is possible to capture and record an image of the child 14 who passes through the gate 13 and goes out to a hand-washing place or the like, which is a place not imaged by the imaging device 10. Therefore, the video imaged by the imaging device 10 is displayed on the monitor display device 16 connected to the control device 12 in real time, or the recorded video image is reproduced and displayed on the monitor display device 16.
The whereabouts of the child 14 can be confirmed more easily. The resonance frequency of the LC resonance circuit is made different for each label and the tag 15, and the resonance frequency of the LC resonance circuit and the child 14 are associated with each other and registered in advance in the database 20 or the memory in the control device 12. . Therefore, in the control device 12 or the data center 2, the child 14 may be identified by the oscillation frequency from the LC resonance circuit. Here, for example, a table as shown in FIG. 11A is provided in the database 20 or the memory 12c in the control device 12, and the correspondence between the data for identifying the monitoring target and the terminal is registered in advance. deep. When using a mobile wireless telephone terminal (mobile phone) as a terminal,
An identification code (for example, a bar code) for identifying the telephone number of the mobile phone 6 which is the delivery destination of the monitoring video signal obtained by imaging the monitoring target and the child 14 who is the monitoring target desired to be monitored by the user of the mobile phone. ), And a reception interval and the like to be described later are registered in the table for each mobile phone by an input circuit (for example, keyboard 17 (FIG. 2), bar code reader, etc.) connected to the database 20 or the control device 12. The name of the child to be monitored may be registered instead of the identification code or together with the identification code. The identification code and the name of the child as data for identifying the monitoring target are information for identifying the monitoring target according to the terminal. In this embodiment,
It is assumed that such a table is provided in the database 20. Alternatively, these data may be input from the mobile radio telephone terminal and registered in the database 20.

Here, as shown in FIG. 8A, the child 1 having the label and the tag 15 attached to the label surface of the label and the tag 15 imaged by the image pickup device 10 is attached.
4, a name for identifying 4 and an identification code are displayed. Therefore, the label surface is attached to the imaging device 1
The control device 12 detects the name display content and the identification code display content of the label surface from the video signal obtained by imaging at 0, and the child 1 imaged according to the detection result.
It is possible to perform the identification determination of 4.

Although not shown, a wireless IC card or the like (for example, an IC card having a wireless communication function having a sensitivity that enables transmission / reception within a range of 1 to 2 m, or the like instead of the above-mentioned LC resonance circuit) IC chip) may be used. In that case, the wireless IC is further provided in the gate 13.
An antenna, a receiver and a transmitter for transmitting and receiving radio signals to and from a card or the like are provided. In addition, each wireless IC
The card records the name of the corresponding child 14 and its identification code. Labels and tags 1
The above-mentioned name and identification code information of the child 14 is transmitted from the wireless IC card 5 or the like to the gate 13, and the transmitted name and identification code information is transmitted from the gate 13 to the control device 12. Based on the transmitted information, the control device 12 can refer to the table shown in FIG. 11 (a) to determine the identification of the imaged child 14.

Then, in accordance with the above-mentioned determination result, which one of the video signals output from the plurality of image pickup devices 10 is a monitoring target corresponding to each mobile phone 6 of the guardian of the child 14. The control device 12 can determine whether the image signal is obtained by imaging a certain child 14. FIG. 4 is a flow chart for explaining the operation of the embodiment of the present invention, and for explaining the processing in the control device 12. Such processing is performed by the control device 12
It is supposed to be executed by a program in the internal memory 12c. First, in step 50, various setting information registered in the table (FIG. 11A) of the database 20 is read. Next, at step 52, which of the video signals captured by the plurality of imaging devices 10 is used to identify which of the video signals the child to be monitored is captured. As an identification method, the image of the child to be monitored may be detected by recognizing the label and / or the identification code on the surface of the tag 15 from the image signal, or both. In step 54, the video signal in which the child to be monitored is picked up in this way is selected, and the video signal selected by the terminal which is the destination of the video of the child to be monitored is selected as the monitoring video signal according to the table of FIG. 11 (a). Data center 2, Internet 3,
It is delivered to the mobile phone via the mobile phone network 4. The distribution interval of the monitor video signal is set according to the reception interval in the table of FIG. The processing of steps 52 and 54 is performed for each child to be monitored.

By the way, when it is determined that the same child 14 is imaged by a plurality of video signals among the video signals output from the plurality of imaging devices 10, which video signal is more distributed. It is necessary to judge whether or not the video signal is suitable for. Therefore, the control device 12 further performs image signal processing to select an appropriate video. For example, for each of the video signals output from the plurality of imaging devices 10, the imaging video range of the target child 14 is detected, and the child 14 within the detected video range is detected.
The imaging area of the face part of the is detected. The detected area is compared between a plurality of video signals, and the video signal having the largest area is selected. Alternatively, for each image range, the number or area of images of the eyes, nose, or mouth present on the face of the child 14 is detected, and an image signal having a larger number or area of images is selected. Then, the selected video signal is set to be video-distributed.

Here, as a means for selecting the above-mentioned video signal, as shown in FIG.
As shown in (a) and FIG. 3 (b), the areas occupying a color tone such as a skin color, which is a characteristic color tone of the face part of the monitored child, are calculated, respectively, and a plurality of captured images are displayed. Comparing the calculated areas, the largest area, or
The video signal with the largest area ratio is selected and delivered. The control device 12 executes such calculation and comparison processing. The calculation / comparison process is executed according to a flowchart shown in FIG. 12, for example.
Such processing is assumed to be executed by the program recorded in the memory 12c in the control device 12. That is, in the flowchart of FIG. 12, first, with respect to the video signals from the respective imaging devices 10, a captured image when a moving object such as the child 14 to be monitored is not captured is registered as a background image (step 10
0). Next, the following processing is performed on the video signal from each imaging device 10. First, the registered background image is compared with the video signal from the imaging device 10 to determine whether or not the video signal includes a moving object (step 102). If it is determined that there is a moving body, the imaging range of the moving body is determined, and the determined range is set as range A (step 104). on the other hand,
If the moving body is not detected, step 102
And try again.

Then, after step 104, the range A
And further about the vicinity of the top of the range A,
Whether or not it is the hair portion is determined according to the hue, the color tone, and the degree of monotonicity thereof (step 106). When it is determined that the vicinity of the top of the range A is the hair part, whether or not the lower part of the hair part in the image range is the skin color part is determined according to the hue, color tone, and degree of monotonicity thereof. The determination is made (step 108). When it is determined that the lower part of the hair portion is the skin-colored portion, the skin-colored portion is set as the face portion, the ratio between the area of the image range of the face portion and the area other than the face portion is obtained, and then the control device 12 In the memory (step 110).

On the other hand, if the result of determination in step 106 is that the hair portion is not detected, step 106 is executed again. If the result of determination in step 108 is that the face portion is not detected, step 108 is executed again. It should be noted that, in these cases, the step 106 and the step 108 are re-executed only for one embodiment, and various combinations of these steps can be considered according to various situations and the like. For example, step 100 may be executed again, or step 106
It is also possible to selectively switch between the operation for re-executing step and the operation for re-executing step.

Next, in step 112, the controller 1 determines the area of the image range of the face portion recorded for each image signal as described above, or the area ratio.
2 compares the respective video signals with each other and selects and delivers the video signal having the largest area or the largest area ratio. Therefore, in the example of FIG. 3, the image of FIG. 3A in which the face area is larger is selected from the images of FIGS. 3A and 3B. is there.

Here, the states of the image pickup device, the child, and the picked-up image when the distribution image is selected will be described with reference to FIGS. 5 and 6. In FIG. 5, the children 14a and 14b who are the monitoring targets in the room of the nursery 1 are the image pickup devices 10 respectively.
The plane arrangement | positioning when imaged by a, 10b, and 10c is shown. Then, FIG. 6 shows a display state by the video signals picked up by the image pickup apparatuses 10a, 10b and 10c in that case. It should be noted that all of these three video signals are video signals that have been identified and determined for the children 14a and 14b, and the video signals to be distributed should be selected from these three video signals.

In this case, in FIG. 6A, the side face of the child 14a and the face portion (face portion) of the child 14b from almost the front are imaged. Further, in FIG. 6B, the face portion of the child 14a from almost the front and the back head of the child 14b are imaged,
The face of the child 14b is not imaged. In addition, FIG.
In (c), the side face portion of the child 14b and the back head portion of the child 14a are imaged, and the face portion of the child 14a is not imaged.

Therefore, in the control device 12, of the three video signals, the face of the child 14a of the child 14a is imaged substantially from the front, and the image is captured by the image pickup device 10b having the largest image capturing area of the face. Selected video signal. Similarly, for the child 14b, the face portion of the child 14b is imaged substantially from the front, and the video signal imaged by the image pickup device 10a having the largest image pickup area of the face portion is selected.

As a result, from the control device 12 to the mobile phone 6 of the guardian of the child 14a, the child 14a
A video signal having a larger amount of information regarding the child 14a (a video signal captured by the image capture device 10b), which is a video signal obtained by capturing the face of the subject from almost the front, is distributed. Similarly, to the mobile phone 6 of the guardian of the child 14b, a video signal having a larger amount of information regarding the child 14b, which is a video signal obtained by capturing the face of the child 14b from almost the front (in the imaging device 10a, The captured image signal) will be distributed.

The control device 12 may be, for example, Japanese Patent Laid-Open No.
The input image described in Japanese Patent Application Laid-Open No. 01-216515 is divided into small areas, candidate eye areas and candidate areas between eyes are detected from the luminance feature of each small area, and candidate areas between eyes and candidates between eyes are detected. It has a face recognition function such as determining the area between the eyes from the positional relationship of the areas and determining the area of the eyes and face so as to include the area between the eyes, and it is detected using that function. From the image of the face portion, it is possible to identify which child 14 the image of the face portion was obtained by imaging.

Further, the control device 12 analyzes the picked-up image signal to generate relative position information between the image pickup device which picked up the image and the imaged and identified child 14, and the information is stored. It may be recorded in a memory in the control device 12. In this case, as shown in FIG. 7, according to the recorded position information, the position of the child 14 to be monitored at each time as indicated by the cross mark is set as the relative position in the monitoring area to the screen of the monitor display device 16. And the locus of the position of the child 14 is connected with a line every time,
The moving state of the child 14 may be displayed. By doing so, even if there is a period in which the label and the tag 15 attached to the child 14 happen to be unable to be imaged, by displaying and confirming the locus of FIG. 7 based on the position information recorded later, the child 14 can be confirmed. You can check the rough position. The position information may be distributed and recorded in the recording device 71 of the monitored child's home 7 and reproduced and displayed on a personal computer or the like at home.

Next, the manner of displaying the monitor video signal and the setting operation in the mobile phone 6 which is a terminal will be described.
FIG. 9 shows a child 1 to be monitored on the mobile phone 6.
4c is displayed. In this figure, the image range of the child 14c is detected by the control device 12, and the image within the detected range has a higher contrast, and the image outside the detected range, that is, the shaded area in the figure is applied. About the part, it is shown that the contrast is displayed lower.
By doing so, the guardian of the child 14c who is visually recognizing the display of the mobile phone 6 can be more easily highlighted by making the image of the child 14c to be monitored more prominent. I can. It should be noted that not only the contrast but also the average luminance level of the portion may be displayed at a lower level.

Regarding the display "INT: 5 min" displayed on the upper right of the display screen in this figure, since the monitoring video distribution system can set the video distribution interval (reception interval), The value of the set delivery interval can be displayed. FIG. 10 shows an example of display of a setting screen on the mobile phone 6 for setting the distribution interval. In the display screen of FIG. 10, "moving image" indicates that a moving image can be selected as a distribution image. When "Movie" is not selected, a still image shall be selected. Also, the display such as "30 seconds", "30 minutes", "1 hour" displayed on the display screen is
Each of these shows an example of still image distribution intervals that can be set. In this figure, the setting of "5 minutes" is surrounded by the setting frame indicated by a thick frame, and the value is set by the mobile phone 6. It is indicated that there is.
