  Shoplifters are misunderstood by ordinary customers, and it is difficult to detect and control crimes. One of the problems that arise when detecting malicious persons such as shoplifters is that it is difficult to accurately distinguish between malicious persons and those who are not. For example, according to the technique described in Patent Document 2, a call for preventing shoplifting is made to the person regardless of whether the person who entered the monitoring area is a malicious person or not. However, when such a call is made to a non-malicious person, it may cause negative feelings such as discomfort and annoyance to the person.

  One exemplary object of the present invention is to provide a technology that contributes to the suppression of criminal acts and does not interfere with non-malicious persons.

  The present invention provides a detecting means for detecting a person who satisfies a predetermined condition, and an environmental sound for associating the detected person with the presence of another person other than the person at a volume equal to or lower than a predetermined volume. There is provided a crime prevention system including sound emission control means for controlling sound emission means so as to be perceived.

  Further, the present invention provides an acquisition means for acquiring data indicating that a person satisfying a predetermined condition has been detected, and an environmental sound reminiscent of the presence of another person other than the person for the detected person. There is provided an information processing apparatus including sound emission control means for controlling sound emission means so as to be perceived at a sound volume equal to or lower than a predetermined sound volume.

  In addition, the present invention detects a person who satisfies a predetermined condition, and perceives the detected ambient sound with a volume equal to or lower than a predetermined volume for the person to associate with the presence of another person other than the person. Provide crime prevention methods that emit sound as they are.

  Further, according to the present invention, there is provided a process for acquiring data indicating that a person satisfying a predetermined condition has been detected, and an environmental sound reminiscent of the presence of another person other than the person for the detected person. There is provided a program for causing a person to execute a process of controlling sound emission means so as to be perceived at a volume equal to or lower than a predetermined volume.

[First Embodiment]
FIG. 1 is a block diagram showing a configuration of an information processing apparatus 100 according to an embodiment of the present invention. As illustrated in FIG. 1, the information processing apparatus 100 includes an acquisition unit 110 and a sound emission control unit 120. The information processing apparatus 100 is, for example, a computer device (such as a personal computer) configured to be communicable with an external device (detection device and sound emitting device), and realizes functions described later by executing a predetermined program.

  The information processing apparatus 100 is an apparatus for suppressing crimes in a facility such as a store. When a person is detected, the information processing apparatus 100 emits a predetermined sound to the person in a predetermined manner so that the person is discouraged when the person intends to commit a crime. Like that. That is, the information processing apparatus 100 functions as a deterrent against crime.

  The acquisition unit 110 acquires data supplied from a detection device that detects a person. The detection device detects a person who satisfies a predetermined condition based on images, sound, infrared rays, and the like. Here, the predetermined condition includes entering a predetermined area, performing a specific action or action, and the like.

  The sound emission control unit 120 controls sound emission by the sound emission device. The sound emission control unit 120 controls the sound emission device so that a predetermined sound is emitted to the person detected by the detection device. The sound emitting device can radiate sound toward a specific position (specifically, near the person detected by the detecting device) by providing a plurality of speakers or controlling directivity. It may be configured.

  The sound emitted by the sound emitting device is an environmental sound that reminds the suspicious person of the existence of another person other than the person. Such an environmental sound may be, for example, a sound that makes a person feel like a sound like a shop clerk or a shopper or a voice. The environmental sound may be a pre-recorded sound, but the sound of another place in the facility (for example, a place crowded with shoppers) is picked up by a microphone, and the picked-up sound is real-time. Sound may be emitted.

  In addition, the sound emission control unit 120 emits an environmental sound so that a person detected by the detection device is perceived at a volume equal to or lower than a predetermined volume. Specifically, the sound emission control unit 120 emits an environmental sound that is perceived at a volume that can be barely heard by a person detected by the detection device.

  The sound emission control unit 120 may determine the volume of the environmental sound by specifying the distance from the speaker to the person detected by the detection device. Alternatively, the sound emission control unit 120 may regard the distance from the speaker to the person as being substantially constant and emit the environmental sound at a predetermined volume.

  According to the information processing apparatus 100 of the present embodiment, it is possible to emit sound so that the above-described environmental sound is perceived at a predetermined volume or less to a person detected by the detection apparatus. Generally, a person who intends a crime such as shoplifting becomes sensitive to surrounding sounds because he / she fears that his / her criminal activity will be revealed to others. Therefore, such a person tends not to miss even a minute sound. In addition, this tendency is more prominent when the audible sound is a sound reminiscent of the presence of another person. Therefore, the information processing apparatus 100 can function as a deterrent against crime.

  On the other hand, a person who is not malicious such as a normal shopper can be said to be less aware of such environmental sound than a malicious person. This is because the environmental sound of the present embodiment is a sound that can normally be generated in a store or the like. It is also true that a person who is not malicious does not care much even if such environmental sounds are heard. The information processing apparatus 100 according to the present embodiment pays attention to such a difference in consciousness between a malicious person and a non-malicious person, and is a sound that is easily perceived by a malicious person but difficult for a non-malicious person. It is something that emits. Thereby, according to the information processing apparatus 100 of the present embodiment, it is possible to prevent a person who is not malicious while preventing contributions to criminal acts.

[Second Embodiment]
FIG. 2 is a block diagram showing a configuration of a crime prevention system 200 according to another embodiment of the present invention. The crime prevention system 200 includes a human sensor 210, a control device 220, a storage device 230, and a sound emitting device 240. The crime deterrence system 200 is a computer system that is installed in a specific facility (retail store or the like) and deters crimes in the facility.

  The human sensor 210 is a sensor for detecting a person. The human sensor 210 detects the presence or absence of a person in a specific area in the facility using, for example, infrared rays or ultrasonic waves. The human sensor 210 may be provided at a plurality of positions in the facility. The human sensor 210 supplies sensor data indicating the output from the sensor to the control device 220.

  The control device 220 controls sound emission by the sound emission device 240 based on the sensor data supplied from the human sensor 210. More specifically, the control device 220 includes a detection unit 221 and a sound emission control unit 222. The detection unit 221 detects a person based on the sensor data. The sound emission control unit 222 controls sound emission by the sound emission device 240 when a person is detected by the detection unit 221. The sound emission control unit 222 corresponds to an example of the information processing apparatus 100 according to the first embodiment.

  The storage device 230 stores environmental sound data. The environmental sound data is data representing the environmental sound described in the first embodiment. That is, in this embodiment, the environmental sound is recorded in advance. The storage device 230 includes a storage medium such as a hard disk. Note that the storage device 230 may be configured as a part of the control device 220.

  The sound emitting device 240 emits (reproduces) environmental sound according to the environmental sound data. The sound emitting device 240 includes a plurality of speakers. The sound emitting device 240 may be configured such that the environmental sound is clearly perceived at a specific position, such as by controlling directivity. The speaker is preferably provided in a conspicuous position so that it is not perceived that environmental sound is emitted from the speaker. In addition, the speaker may reflect the environmental sound on a wall surface or the like and make the person perceive it as a reflected sound.

  The number of speakers and human sensors 210 of the sound emitting device 240 is not particularly limited. However, in the following, it is assumed that there are a plurality of speakers and human sensors 210 for convenience of explanation. For example, the human sensor 210 is provided at a plurality of positions in the facility and detects the presence or absence of a person in different areas. For example, the same number of speakers as the human sensors 210 are provided so that each speaker is associated with one of the human sensors 210.

  The configuration of the crime prevention system 200 is as described above. In this configuration, the control device 220 detects a person using the sensor data, and controls to emit an environmental sound when a person is detected.

  FIG. 3 is a flowchart showing an outline of the operation of the control device 220. First, the detection unit 221 acquires sensor data from the plurality of human sensors 210 (step S21). Based on the sensor data, the detection unit 221 determines whether or not a person has been detected in any of a plurality of areas (step S22). In other words, the detection unit 221 detects a person who has entered a specific area in the facility. When the detection unit 221 detects a person in any area, the detection unit 221 supplies data indicating the area (or the human sensor 210 corresponding to the area) to the sound emission control unit 222.

  When the detection unit 221 detects a person (step S22: YES), the sound emission control unit 222 reads the environmental sound data from the storage device 230 and supplies the environmental sound data to the sound emission device 240 (step S23). Specifically, the sound emission control unit 222 outputs the environmental sound data so that the environmental sound is emitted by the speaker corresponding to the area where the person is detected (or the human sensor 210 corresponding to the area). . At this time, the sound emission control unit 222 may supply the sound emission device 240 with parameters for controlling directivity and volume. In addition, the sound emission control part 222 skips the process of step S23 (omitted), when the detection part 221 does not detect a person (step S22: NO).

  According to the crime prevention system 200 of the present embodiment, it is possible to obtain the same effect as that of the first embodiment. Moreover, according to this crime prevention system 200, by using the human sensor 210, an environmental sound is emitted so as to be perceived only by a person in a specific area. Therefore, according to the crime prevention system 200, it is possible to radiate environmental sound to a necessary area in a pinpoint manner.

[Third Embodiment]
FIG. 4 is a block diagram showing a configuration of a crime prevention system 300 according to still another embodiment of the present invention. The crime prevention system 300 includes a photographing device 310, a control device 320, a storage device 230, and a sound emitting device 240. The crime prevention system 300 is different from the crime prevention system 200 of the second embodiment in that the photographing device 310 and the control device 320 are provided, and has the same configuration as the crime prevention system 200 in other points. In the present embodiment, descriptions of matters common to the second embodiment are omitted as appropriate.

  The imaging device 310 images the inside of the facility. The photographing apparatus 310 includes one or a plurality of cameras. The imaging device 310 generates image data and supplies it to the control device 320. Note that the image shot by the shooting device 310 is not a still image but a moving image.

  The control device 320 analyzes the image data supplied from the photographing device 310 and controls sound emission by the sound emission device 340. More specifically, the control device 320 includes a detection unit 321 and a sound emission control unit 322. The detection unit 321 detects a suspicious person based on the image data. The sound emission control unit 322 controls sound emission by the sound emission device 340 when the detection unit 321 detects a suspicious person. The sound emission control unit 322 corresponds to an example of the information processing apparatus 100 according to the first embodiment.

  The configuration of the crime prevention system 300 is as described above. In this configuration, the control device 320 detects the suspicious person using the image data, and controls to emit the environmental sound when the suspicious person is detected. This embodiment and 2nd Embodiment differ in the conditions for detecting a person. As described above, the detection unit 221 detects a person who has entered a predetermined area (whether or not it is a suspicious person). On the other hand, the detection unit 321 detects a person who is photographed by the photographing apparatus 310 and recognized as performing a specific action or action as a suspicious person.

  FIG. 5 is a flowchart showing the operation of the control device 320. First, the detection unit 321 acquires image data from the imaging device 310 (step S31). The detecting unit 321 determines whether or not a suspicious person has been detected based on the image data (step S32). Specifically, the detection unit 321 first determines whether a person is included in the image indicated by the image data. Then, when a person is included in the image, the detection unit 321 analyzes the action or action of the person and determines whether or not the action or action corresponding to the suspicious person is being performed.

  The action or action corresponding to the suspicious person is, for example, a state in which the surroundings are looked around in a calm state, or a state in which the same place is visited many times. A pattern of an action or action corresponding to a suspicious person may be registered in the control device 320 (or the storage device 230) in advance. In addition, the technique which detects a suspicious person by the operation | movement is disclosed by Unexamined-Japanese-Patent No. 2014-026506, for example.

  When the detection unit 321 detects a suspicious person, the detection unit 321 supplies data indicating that to the sound emission control unit 322. The detection unit 321 may supply the sound emission control unit 322 with data specifying a speaker to emit sound and information indicating an area where a suspicious person is detected (or a camera that has captured the suspicious person).

  When the detection unit 321 detects a suspicious person, the sound emission control unit 322 reads the environmental sound data from the storage device 230 and supplies the environmental sound data to the sound emission device 240 (step S33). Specifically, the sound emission control unit 322 outputs environmental sound data so that the environmental sound is emitted by a speaker close to the position where the suspicious person is detected. At this time, the sound emission control unit 322 may supply the sound emission device 240 with parameters for controlling directivity and volume. In addition, the sound emission control part 322 skips the process of step S33, when the detection part 321 does not detect a person (step S32: NO).

  According to the crime prevention system 300 of this embodiment, it is possible to obtain the same effects as those of the first embodiment and the second embodiment. Further, according to the crime prevention system 300, only a specific person (that is, a person who has performed a predetermined action or action) is determined by determining the movement of the person based on the image data photographed by the photographing device 310. On the other hand, it is possible to emit an environmental sound. Therefore, according to the crime prevention system 300, it is possible to emit an environmental sound only to a person who is determined to be a suspicious person and not to emit an environmental sound to other persons. It is.

[Fourth Embodiment]
FIG. 6 is a block diagram showing a configuration of a crime prevention system 400 according to still another embodiment of the present invention. The crime prevention system 400 includes a photographing device 310, a control device 420, a storage device 230, and a sound emitting device 240. The crime prevention system 400 is different from the crime prevention system 300 of the third embodiment in that the control device 420 is provided, and has the same configuration as the crime prevention system 300 in other points. In the present embodiment, descriptions of matters common to the third embodiment are omitted as appropriate.

  The control device 420 includes a detection unit 421, a sound emission control unit 422, and a recording unit 423. The sound emission control unit 422 has the same function as the sound emission control unit 322 of the third embodiment. The detection unit 421 has a function of detecting the behavior of a suspicious person after sound emission of environmental sound, in addition to the same function as the detection unit 321 of the third embodiment. When the behavior of the suspicious person detected by the detection unit 421 corresponds to a predetermined behavior, the recording unit 423 records information regarding the person in the storage device 230.

  FIG. 7 is a flowchart showing the operation of the control device 420. In this flowchart, the processes of steps S41 to S43 are the same as the processes of steps S31 to S33 (see FIG. 5) of the third embodiment.

  The detection unit 421 analyzes the behavior of the person determined to be a suspicious person after outputting the environmental sound data in step S43 (step S44). Specifically, the detection unit 421 analyzes the response of the person who is determined to be a suspicious person to the environmental sound. The detecting unit 421 determines whether or not the behavior analyzed in step S44 corresponds to a predetermined behavior (step S45).

  In step S <b> 45, the detection unit 421 makes a positive determination when the user is surprised by the environmental sound or when the reaction is suddenly left. A person who shows such a response to environmental sound is likely to have attempted a criminal act. On the other hand, people who are not malicious are often not particularly aware of environmental sounds or do not perceive environmental sounds in the first place, and are more likely not to respond to environmental sounds as malicious people do. . The detection unit 421 determines whether or not to perform recording by the recording unit 423 based on such a difference in reaction.

  When the detection unit 421 determines that the person determined to be a suspicious person has taken a predetermined action (step S45: YES), the recording unit 423 records information about the person in the storage device 230 (step S46). ). For example, the recording unit 423 records, in the storage device 230, image data obtained by photographing all or part of a person determined to be a suspicious person (such as a face). The recording unit 423 may record other information that contributes to the identification or identification of the person in the storage device 230. Such information includes, for example, information indicating the age and sex determined from the physical characteristics of the person (pupil color, hair color, skin color, physique, etc.) and appearance. Further, the recording unit 423 may record the photographing time of the person and the entrance / exit time of the facility together with the image data.

  According to the crime prevention system 400 of the present embodiment, the same effects as those of the first to third embodiments can be obtained, and a so-called black list can be created. A user (such as an employee of a facility) of the crime prevention system 400 can easily know that a person similar to the recorded person has revisited the facility by referring to the information recorded by the recording unit 423. It becomes possible. For example, this information can be used in combination with a well-known face recognition technique to recognize a person when the recorded person is photographed by a surveillance camera or the like.
