  According to the video display device of the present invention, it is possible to give the suspicious person the consciousness of being monitored and discourage entry into the building.

  Embodiments of the present invention will be described below with reference to the drawings. In the description of the drawings, the same portions are denoted by the same reference numerals, and description thereof is omitted. In the embodiment of the present invention, description will be made by taking, as an example, an entrance door installed at the entrance of a house and a gate pillar installed near the boundary between a site and a road as a place where the display unit of the video display device is installed. Specifically, the front door provided with the video display device of the present invention in the first embodiment of the present invention will be described, and the gate pillar provided with the video display device of the present invention in the second embodiment of the present invention. Will be described.

(First embodiment)
First, with reference to FIG. 1A and FIG. 1B, an installation example of the entrance door 4 according to the first embodiment will be described. House 1 is built in site 3 and one end of site 3 faces road 2. The house 1 includes a front door as an entrance, and the front door 4 is attached to the front door. In addition, in the installation example of FIG. 1A and FIG.

  Next, with reference to FIG.3 and FIG.4, the detailed structure of the entrance door 4 is demonstrated. As shown in FIG. 3, a display unit 22 is installed at a substantially central portion in the horizontal direction on the outdoor surface of the entrance door 4, and a first human sensor 23a and a second human sensor are respectively provided at both ends in the horizontal direction. A sensor 23b is installed. The display unit 22 displays an image including at least eyes.

  Here, the “eyes” included in this video include eyes of real humans, animals, real machines such as robots, cameras, etc., and eyes represented by colors, lines, and shapes. . The eye image may be a still image or a moving image such as an animation or a video taken by a video camera. Although a still image cannot express blinks or the like, a moving image of a real eye such as blinks can be realistically expressed by using a moving image.

  The first human sensor 23a and the second human sensor 23b each detect a person around the display unit 22. In the example of FIG. 3, the entrance door 4 is an outward opening type door that opens outwardly with the vicinity of the left end as a rotation center, and a knob 21 is attached in the vicinity of the right end. Of course, the front door 4 may be an outside opening type that opens to the right side, a double opening type, a double door opening type, or a sliding door. Moreover, although the height which installs the display part 22 should just match with the height of the eyes of the person who exists in an outdoor side, it does not restrict to this. The height at which the human sensors 23a and 23b are installed is not limited to the height shown in FIG. 3 as long as it can detect a person on the outside of the door.

  As shown in FIG. 4, a video control unit 24 for controlling a video displayed on the display unit 22 is disposed adjacent to the display unit 22 on the AA cut plane of FIG. 4 is connected to the first human sensor 23a and the second human sensor 23b by wires that do not appear in the cross section.

  The first human sensor 23a includes a sensitivity area SAa extending outside the entrance door 4, and senses that a person is present in the sensitivity area SAa. Similarly, the second human sensor 23b includes a sensitivity area SAb extending outside the entrance door 4, and senses that a person is present in the sensitivity area SAb.

  The sensitivity region SAa is formed approximately on the first human sensor 23a side from the display unit 22, and the sensitivity region SAb is formed approximately on the second human sensor 23b side from the display unit 22. Therefore, when there is a person on the outside of the entrance door 4 on the first human sensor 23a side with respect to the display unit 22, the first human sensor 23a detects the presence of the person, but the second human sensor. The sensor 23b does not sense the presence of a person. On the other hand, when a person is present on the second human sensor 23b side of the display unit 22 on the outside of the entrance door 4, the second human sensor 23b detects the presence of the person. The sense sensor 23a does not sense the presence of a person.

  In the example of FIG. 4, a part of the sensitivity area SAa and a part of the sensitivity area SAb are overlapped approximately in front of the display unit 22. Therefore, when there is a person in front of the display unit 22, the first human sensor 23a and the second human sensor 23b simultaneously sense the presence of the person.

  The sensitivity area SAa and the sensitivity area SAb are set so that the position of the person on the outside of the entrance door 4 can be determined from the detection results of the first human sensor 23a and the second human sensor 23b. It suffices to be provided, and is not limited to the example of FIG. For example, the sensitivity area SAa and the sensitivity area SAb may not partially overlap each other.

  The video control unit 24 changes the display content of the display unit 22 according to the detection results of the first human sensor 23a and the second human sensor 23b. Specifically, the first human sensor 23a and the second human sensor 23b each transmit a detection result signal indicating whether or not the presence of a person is detected to the video control unit 24 at a predetermined period. The video control unit 24 receives each sensing result signal and changes the display content of the display unit 22 according to the sensing result signal.

  Next, with reference to FIGS. 5A to 5E, a video example of the display unit 22 changed by the video control unit 24 will be described. The video control unit 24 controls the display unit 22 to display videos as shown in FIGS. 5A to 5E toward the outside of the entrance door 4. Here, as an example of an image including an eye, an image including an eye represented by a color, a line, and a shape of an actual eye will be described as an example. However, an image of an actual eye may be used.

  When the first human sensor 23a does not sense the presence of a person but the second human sensor 23b senses the presence of a person, the video control unit 24 includes the first human sensor 23a and It is determined from the detection result of the second human sensor 23b that there is a person closer to the second human sensor 23b than the display unit 22. Then, the video control unit 24 changes the display content of the display unit 22 so that the display unit 22 displays the video of the eyes facing the second human sensor 23b as shown in FIG. .

  When the first human sensor 23a senses the presence of a person but the second human sensor 23b does not sense the presence of a person, the video control unit 24 uses the first human sensor 23a and It is determined from the detection result of the second human sensor 23b that there is a person closer to the first human sensor 23a than the display unit 22. Then, the video control unit 24 changes the display content of the display unit 22 so that the display unit 22 displays the video of the eyes facing the first human sensor 23a as shown in FIG. 5B. .

  When both the first human sensor 23a and the second human sensor 23b detect the presence of a person, the video control unit 24 detects the first human sensor 23a and the second human sensor 23b. From the result, it is determined that there is a person in front of the display unit 22. Then, the video control unit 24 changes the display content of the display unit 22 so that the display unit 22 displays the video of the eyes facing the front as shown in FIG.

  In this way, since the first human sensor 23a and the second human sensor 23b can look in the direction in which the person is present, the video control unit 24 can detect the person detected by the human sensors 23a and 23b. The video can be controlled so as to follow the eyes displayed on the display unit 22.

  When both the first human sensor 23a and the second human sensor 23b do not sense the presence of a person, the video control unit 24 uses the first human sensor 23a and the second human sensor 23b. It is determined that there is no person around the display unit 22 based on the detection result. Then, the video control unit 24 changes the display content of the display unit 22 so that the display unit 22 displays the video of the eyes in a laughed state as shown in FIG.

  5 (a) to 5 (d) show an example in which an image consisting only of eyes is displayed on the display unit 22, but as shown in FIG. The video may be displayed on the display unit 22. In the example of FIG. 5 (e), the current time is illustrated as an example of other images. However, in addition to this, at least one of external temperature, carbon dioxide concentration, and local communication matters is included. It may be displayed together with the video.

  Further, although not shown in FIG. 5, as other images, images of elements other than the eyes constituting the face such as mouth, nose and eyebrows and images of other elements constituting the body such as shoulders and arms are also combined. May be displayed. Further, for example, in FIG. 5 (a) to FIG. 5 (c), a normal mouth image is displayed, and in FIG. 5 (d), other images are displayed, such as a laughed mouth image. The display content of the unit 22 may be changed.

  As described above, according to the first embodiment of the present invention, the following operational effects can be obtained.

  As an example of the surroundings of the house 1, the display unit 22 is installed toward the outside of the entrance door 4, an image including eyes is displayed on the display unit 22, and the display unit 22 is displayed according to the detection results of the human sensors 23 a and 23 b. By changing the display content of, the suspicious person who tries to enter the house 1 while paying attention to the person is recognizing that the image including the eyes is reacting to himself and strengthens the consciousness of being monitored. Increase alertness. Therefore, the crime prevention effect which makes a suspicious person think about invasion is acquired. Further, since at least one display unit 22 may be provided, the display unit 22 can be provided in a part of the entrance door 4. In addition, since the display unit 22 only needs to display an image including eyes, the display area can be small. In addition, since a security camera is not required, the problems of securing the installation location and increasing the cost can be solved.

  As shown in the respective diagrams of FIG. 5, the video control unit 24 controls the video so as to follow the person detected by the human sensors 23 a and 23 b with the eyes displayed on the display unit 22. The suspicious person detected by the sensors 23a and 23b recognizes that the person is being chased by the eyes displayed on the display unit 22, strengthens the consciousness of being monitored, and increases alertness. Therefore, the crime prevention effect which makes a suspicious person think about invasion can be heightened.

  The image control unit 24 controls the display unit 22 to display an image including a laughing eye when the human sensors 23a and 23b do not detect a person, for example, a good faith No discomfort to the person, and communication with the neighborhood can be facilitated.

  The video control unit 24 controls the display unit 22 to display at least one of the current time, the external temperature, the carbon dioxide concentration, and the communication items in the area together with the video including the eye. Since part 22 can also be used as a means of communication with neighboring residents, it is useful for crime prevention. Moreover, since the activeness of the communication can be appealed to the outside, it is possible to increase the alertness of a person who tries to intrude while taking care of human eyes, and to enhance the crime prevention effect that discourages intrusion.

(Second Embodiment)
First, with reference to FIG. 1 (a) and FIG.1 (b), the example of installation of the gate pillar 11 concerning 2nd Embodiment is demonstrated. A passage 6 used for traffic from the road 2 to the entrance door 4 is formed in the site 3 so as to connect the entrance door 4 and the road 2. The gate pillar 11 is one end of the site 3 facing the road 2 and is used in the vicinity of the passage 6. The installation example of the gate pillar 11 illustrated in FIG. 1 is an example around the building 1, and is not limited thereto, and the gate pillar 11 may be installed in another place around the building 1.

  Next, with reference to FIG.6 and FIG.7, the detailed structure of the gate pillar 11 is demonstrated. As shown in FIG. 6, the gate pillar 11 includes a display unit 32, a first human sensor 33 a and a second human sensor 33 b, an illuminated nameplate 36, and interphone slave units (31, 35). .

Similarly, the second human sensor 33b includes a sensitivity region SBb extending on the road 2 side of the gate pillar 11, and senses that there is a person in the sensitivity region SBb.

  The sensitivity region SBa is formed approximately on the first human sensor 33a side from the display unit 32, and the sensitivity region SBb is formed approximately on the second human sensor 33b side from the display unit 32. Therefore, on the road 2 side of the gate pillar 11, when there is a person on the first human sensor 33a side with respect to the display unit 32, the first human sensor 33a detects the presence of the person, but the second human sensor The sensor 33b does not sense the presence of a person. Conversely, when there is a person on the side of the road 2 of the gate pillar 11 closer to the second human sensor 33b than the display unit 32, the second human sensor 33b detects the presence of the person. The sensor 33a does not detect the presence of a person.

  In the example of FIG. 7, a part of the sensitivity area SBa and a part of the sensitivity area SBb are overlapped approximately in front of the display unit 32. Therefore, when there is a person in front of the display unit 32, the first human sensor 33a and the second human sensor 33b simultaneously sense the presence of the person. The sensitivity area SBa and the sensitivity area SBb are set so that the position of the person on the road 2 side of the gate pillar 11 can be determined from the detection results of the first human sensor 33a and the second human sensor 33b. It suffices to be provided, and is not limited to the example of FIG. For example, the sensitivity area SBa and the sensitivity area SBb may not partially overlap each other.

  The video control unit 34 changes the display content of the display unit 32 according to the detection results of the first human sensor 33a and the second human sensor 33b. Specifically, the first human sensor 33a and the second human sensor 33b each transmit a detection result signal indicating whether or not the presence of a person is detected to the video control unit 34 at a predetermined cycle. The video control unit 34 receives each detection result signal, and changes the display content of the display unit 32 according to the detection result signal.

  Next, a video example of the display unit 32 changed by the video control unit 34 will be described with reference to FIGS. The video control unit 34 controls the display unit 32 to display videos as shown in FIGS. 8A to 8D toward the road 2 side of the gate pillar 11. Here, as an example of an image including an eye, an image including an eye represented by a color, a line, and a shape of an actual eye will be described as an example. However, an image of an actual eye may be used.

  When the first human sensor 33a does not detect the presence of a person but the second human sensor 33b detects the presence of a person, the video control unit 34 includes the first human sensor 33a and the first human sensor 33a. It is determined from the detection result of the second human sensor 33b that there is a person closer to the second human sensor 33b than the display unit 32. Then, the video control unit 34 changes the display content of the display unit 32 so that the display unit 32 displays the video of the eyes facing the second human sensor 33b as shown in FIG. 8A. .

  When the first human sensor 33a detects the presence of a person but the second human sensor 33b does not detect the presence of a person, the video control unit 34 includes the first human sensor 33a and the first human sensor 33a. It is determined from the detection result of the second human sensor 33b that there is a person closer to the first human sensor 33a than the display unit 32. Then, the video control unit 34 changes the display content of the display unit 32 so that the display unit 32 displays a video image of the eyes facing the first human sensor 33a as shown in FIG. 8B. .

  When both the first human sensor 33a and the second human sensor 33b detect the presence of a person, the video controller 34 detects the first human sensor 33a and the second human sensor 33b. From the result, it is determined that there is a person in front of the display unit 32. Then, the video control unit 34 changes the display content of the display unit 32 so that the display unit 32 displays the video of the eyes facing the front as shown in FIG.

  In this way, since the first human sensor 33a and the second human sensor 33b can look in the direction in which the person is present, the video control unit 34 can detect the person detected by the human sensors 33a and 33b. The video can be controlled so as to follow the eyes displayed on the display unit 32.

  When both the first human sensor 33a and the second human sensor 33b do not sense the presence of a person, the video controller 34 selects the first human sensor 33a and the second human sensor 33b. It is determined that there is no person around the display unit 32 based on the detection result. Then, the video control unit 34 changes the display content of the display unit 32 so that the display unit 32 displays the video of the eyes in a laughed state as shown in FIG.

  8 (a) to 8 (d) show an example in which a video composed of only eyes is displayed on the display unit 32. However, as in FIG. 5 (e), the current time, Other images such as external temperature, carbon dioxide concentration, and local communication items may be displayed on the display unit 32. Although not shown in FIG. 8, as other images, images of elements other than the eyes constituting the face such as mouth, nose and eyebrows and images of other elements constituting the body such as shoulders and arms are also combined. May be displayed. Further, for example, in FIGS. 8A to 8C, a normal mouth image is displayed, and in FIG. 8D, a laughed mouth image is displayed. The display content of 32 may be changed.

  As described above, according to the second embodiment of the present invention, the following operational effects can be obtained.

By changing the display content, the suspicious person who wants to enter the site 3 where the house 1 was built while paying attention to the person is recognized and recognized that the image containing the eyes is reacting to him. Enhance awareness and raise alertness. Therefore, the crime prevention effect which makes a suspicious person think about invasion is acquired. Further, since at least one display unit 32 may be provided, the display unit 32 can be provided in a part of the gate pillar 11. Further, since the display unit 32 only needs to display an image including eyes, the display area can be small.

  As shown in the respective diagrams of FIG. 8, the video control unit 34 controls the video so that the human being detected by the human sensors 33a and 33b is followed by the eyes displayed on the display unit 32. The suspicious person detected by the sensors 33a and 33b recognizes that the suspicious person is being chased by the eyes displayed on the display unit 32, strengthens the consciousness of being monitored, and increases alertness. Therefore, the crime prevention effect which makes a suspicious person think about invasion can be heightened.

  The image control unit 34 controls the display unit 32 to display an image including a laughing eye when the human sensors 33a and 33b are not detecting a person, for example, in good faith such as neighboring residents. No discomfort to the person, and communication with the neighborhood can be facilitated.

  The video control unit 34 controls the display unit 32 so as to display at least one of the current time, the external temperature, the carbon dioxide concentration, and the communication items in the area together with the video including the eye. Since the part 32 can be used as a means of communication with neighboring residents, it is useful for crime prevention. Moreover, since the activeness of the communication can be appealed to the outside, it is possible to increase the alertness of a person who tries to intrude while taking care of human eyes, and to enhance the crime prevention effect that discourages intrusion.

(Other embodiments)
As described above, the present invention has been described in terms of two embodiments, but it should not be understood that the discussion and drawings that form part of this disclosure limit the present invention. From this disclosure, various alternative embodiments, examples, and operational techniques will be apparent to those skilled in the art.

  In the first embodiment, the entrance is given as an example of the entrance and exit of the house 1 and the entrance door 4 installed at the entrance has been described. However, other entrances and exits of the house 1 such as the entrance door that is installed at the entrance. The video display device of the present invention is also applicable. Moreover, although the house 1 was demonstrated as an example of a building, the video display apparatus of this invention is applicable also to buildings other than a house.

  In the gate pillar 11 of the second embodiment, the case where the image is displayed with the display unit 32 facing the road 2 side has been described. However, the display unit is configured to display the image in another direction, for example, the channel 6 side. 32 may be installed. In this case, the orientations of the sensitivity regions of the first human sensor 33a and the second human sensor 33b are also adjusted together with the display unit 32.

  Moreover, although the front door 4 and the gate pillar 11 to which the video display device of the present invention is applied have been described in different embodiments, of course, they may be combined.

  The video display device may further include a traffic counting unit that counts the number of times that a person goes to the house 1, and the number of times may be displayed on the display units 22 and 32. Each time the first human sensor 23a, 33a or the second human sensor 23b, 33b detects a person around the display unit 22, 32, a detection signal is transmitted to the traffic counting unit. Each time the traffic counting unit receives a sensing signal, the traffic counting unit increments a counter included in the traffic counting unit and transmits a data signal of the counter value to the display units 22 and 32. The display units 22 and 32 display the counter value together with the video including the eyes according to the received counter value data signal.

  In this way, by displaying the number of visits to the house 1 on the display units 22 and 32, it is possible to give the person who intends to invade the person 1 the person who intends to invade, to increase the alertness of the person concerned, An intrusion deterrent effect is obtained.

  Although the case where the number of times of traffic is displayed on the display units 22 and 32 and notified to the surroundings through human vision has been described, the number of times of traffic may be notified to the surroundings by other means (for example, voice / hearing).
