(Embodiment 1)
[Configuration example]
First, the structure of the lighting control system in this Embodiment is demonstrated using FIG. 1, FIG.

  FIG. 1 is a block diagram illustrating a configuration example of a lighting control system according to an embodiment. Moreover, FIG. 2 is a figure which shows the example of arrangement | positioning of the lighting control system in embodiment.

  The lighting control system of FIG. 1 includes a plurality of lighting fixtures 100, a plurality of imaging devices 200, and a control device 300. This lighting control system is installed in a store, for example, a bookstore, and performs appropriate illumination to make it easy to see an article (for example, a book) taken by a person (customer). FIG. 2 shows an arrangement example of the lighting control system installed in the bookstore. In the store of FIG. 2, a bookcase 500, a plurality of lighting fixtures 100a, a plurality of lighting fixtures 100b, and a plurality of imaging devices 200 are installed.

  The bookcase 500 has a four-level bookcase and a flat shelf, and various books are arranged.

  The lighting fixture 100a and the lighting fixture 100b are both specific examples of the lighting fixture 100 of FIG. The lighting fixture 100a has a straight tube type light source unit. The luminaire 100b is a suspended downlight. Hereinafter, an example in which the object to be controlled by the control device 300 is the lighting fixture 100b that is a downlight will be described. However, the lighting fixture 100a or both may be used.

  A circular broken line frame indicates an illumination area where illumination light of the lighting apparatus 100b reaches. The illumination area a1 corresponds to the foremost lighting fixture 100b. The illumination area a2 corresponds to the second luminaire 100b from the front. The same applies to the illumination areas a3 and a4.

  The plurality of imaging devices 200 are arranged on the ceiling at equal intervals (for example, 2 m intervals). The imaging range of the imaging device 200 is arranged to include one or more illumination areas. For example, the imaging device 200 is arranged so that one imaging region includes two illumination regions. In addition, the plurality of imaging apparatuses 200 have different imaging portions of the bookshelf 500 in the illumination area (that is, the entire illumination area) by the plurality of lighting apparatuses 100 (here, the lighting apparatus 100b). That is, the range obtained by combining the imaging ranges of the plurality of imaging devices 200 corresponds to the entire bookshelf (covers the entire bookshelf).

[Configuration example of lighting equipment]

  Each of the plurality of lighting fixtures 100 includes a light source unit 110, a lighting circuit 111, a control circuit 112, a communication unit 113, a storage unit 114, and a power supply circuit 115.

  The light source unit 110 includes one or more light emitting elements. The one or more light emitting elements are, for example, a plurality of LED (Light Emitting Diode) elements. Note that the one or more light emitting elements are not limited to LED elements. The light source unit 110 may include, for example, a semiconductor light emitting element such as a semiconductor laser, and a solid light emitting element such as an organic EL (Electro Luminescence) or an inorganic EL. Further, the light source unit 110 may be a straight tube type such as the lighting fixture 100a of FIG. 2, or may be an annular fluorescent lamp, or may be a so-called downlight such as the lighting fixture 100b of FIG.

  The lighting circuit 111 supplies the light source unit 110 with a voltage or current corresponding to lighting, blinking, extinguishing, etc. of the light source unit 110. When the light source unit 110 is a plurality of LED elements, this voltage or current varies depending on the illumination mode such as the dimming ratio and the toning ratio.

  The control circuit 112 controls the lighting circuit 111 corresponding to a plurality of illumination modes. The control circuit 112 performs control for realizing each of the plurality of functions of the lighting fixture 100. The plurality of functions include, for example, a dimming function for adjusting brightness, a toning function for adjusting color temperature, a fade function for adjusting brightness over time, and the like. The control circuit 112 follows the command received from the control device 300 via the communication unit 113.

  The communication unit 113 communicates with the control device 300. The communication unit 113 receives a command for instructing light adjustment or color adjustment from the control device 300. Although FIG. 2 shows an example in which the communication unit 113 performs wired communication, wireless communication may be used.

  The storage unit 114 stores commands or data received by the communication unit 113.

  The power supply circuit 115 supplies power to each part in the lighting fixture 100.

[Configuration example of imaging device]
Next, a configuration example of the imaging device 200 in FIG. 1 will be described.

  The imaging apparatus 200 includes a camera 210, a motion detection unit 212, and a communication unit 211.

  The camera 210 images people and objects in the illumination area of the at least one luminaire 100. In the bookstore arrangement example of FIG. 2, the camera 210 images people and objects in two illumination areas. In the example of arrangement in the bookstore of FIG. 2, the thing is a book.

  The motion detection unit 212 detects a human motion from the video of the camera 210. Specifically, the motion detection unit 212 detects that an operation in which a person picks up an object and that a state in which the person holds an object in the hand continues. In the example of the bookstore in FIG. 2, the motion detection unit 212 detects an operation in which a person picks up a book from the bookshelf 500, and the person opens the book and holds it in his hand as if the person has an object in his hand. Detect state.

  Furthermore, the detection of the movement of a person and an object by the motion detection unit 212 will be described in more detail.

  3A, 3B, and 3C are diagrams each showing an example of an action or state of a person and an object detected by the motion detection unit 212 in FIG.

  In FIG. 3A, the motion detection unit 212 detects “a person has entered the imaging range” or “a person is in front of the bookshelf”.

  In FIG. 3B, the motion detection unit 212 detects “an action in which a person picks up the object”, that is, “an action in which a person picks up a book from a bookcase” or “an action in which a person returns an object held in the hand”. To do.

  In FIG. 3C, the motion detection unit 212 detects “a person continues to hold an object”, “a person is browsing” or “a person is browsing”. .

  The motion detection unit 212 is not limited to the examples of FIGS. 3A to 3C, and may detect the next operation or state. That is, "an action that another person picks up another object", "an action that hides an object without returning the object that the person has in hand", "a book that a person picks up from the bookshelf `` Moved out of the imaging range while holding it in his hand '', `` Moved out of the imaging range in a state where the person took a book from the bookshelf and hidden it without returning it to the bookshelf '', `` “Out of the imaging range”. Note that these motions may be detected by the motion detector 212 alone or by the CPU 310 based on a combination of detection results of the motion detector 212.

  The communication unit 211 transmits the detection result of the motion detection unit 212 to the communication unit 312 in the control device 300. The transmitted detection result indicates a specific human movement detected by the movement detection unit 212.

[Configuration example of control device]
Next, a configuration example of the control device 300 in FIG. 1 will be described.

  The control device 300 includes a CPU 310, a memory 311, a communication unit 312, an operation unit 313, and a timer unit 314.

  The CPU 310 performs lighting control of the plurality of lighting fixtures 100 by executing a program stored in the memory 311.

  The memory 311 stores programs and data. The program stored in the memory 311 includes a lighting control program 31. The lighting control program 31 is a program for controlling the plurality of lighting fixtures 100 according to the movement of the person and the object detected by the motion detection unit 212. Further, the data stored in the memory 311 includes arrangement data 32. The arrangement data 32 is data in which the imaging device 200 and the lighting fixture 100 in which the imaging range of the camera 210 overlaps with the illumination area of the lighting fixture 100 are associated with each other. For example, in the example of FIG. 2, the foremost imaging device 200 and the two foremost lighting fixtures 100b are associated with each other. The other imaging device 200 is similarly associated with the lighting fixture 100b.

  The CPU 310 selects a lighting fixture 100 associated with the imaging device 200 that has captured the motion-detected video among the plurality of imaging devices 200 according to the arrangement data 32, and selects the selected lighting fixture 100 as a control target. To do.

  The communication unit 312 receives the motion detection result from the communication unit 211 and notifies the CPU 310 of the motion detection result.

  The operation unit 313 receives a user operation related to lighting control.

  The timekeeping unit 314 is a real-time clock or a timer / counter, and is used for measuring a predetermined time.

  Furthermore, control of the some lighting fixture 100 by CPU310 running the lighting control program 31 is demonstrated. FIG. 4 is an explanatory diagram illustrating a human motion detection result and illumination light control in the embodiment. FIG. 4 shows a schematic diagram of a person imaged from above in FIG. 2 and a time-series change in the color temperature of the illumination light of the luminaire 100 controlled by the CPU 310.

  In FIGS. 4A, 4B, and 4C, the motion detection unit 212 indicates that “a person has entered the imaging range”, “a person is in front of the bookshelf”, and “a person is holding an object. ”(Operation to pick up a book from the bookshelf)”. During (a), (b), and (c) of FIG. 4, the luminaire 100 that illuminates this person illuminates at a normal color temperature. The normal color temperature (also referred to as the first color temperature) may be a color temperature between 3500K and 5000K, for example.

  In FIG. 4C, the motion detection unit 212 detects “an action in which a person picks up a book from a bookcase”. In response to this detection result, the CPU 310 sets the second color temperature of the illumination light higher than the normal first color temperature for one of the plurality of lighting fixtures 100 where the illumination light reaches the object. The color temperature is controlled to The second color temperature may be approximately 6200K, for example. Further, the CPU 310 may control the brightness at the second color temperature to 750 lux or more recommended as the illuminance for reading a book. Thereby, a person can read a book comfortably. Furthermore, in order to make the person perceive that the color temperature has changed, it makes the person feel that something is being seen, so there is a crime prevention effect.

  In (d) of FIG. 4, the motion detection unit 212 indicates that the motion detection unit 212 is “a person continues to hold an object in his / her hand”, “a person is browsing” or “a person ”Is being browsed”.

  Furthermore, the CPU 310 controls the lighting apparatus 100 to return to the normal temperature (first color temperature) in (e) when the continuation of the state of (d) exceeds a certain time. Here, the fixed time is set as a time that allows browsing, and for example, it may be 3 to 10 minutes, and an appropriate time according to the condition of the store, the type of the book, the sales situation of the book, etc. It can be set for each bookcase 500, for each imaging device 200, or for each lighting fixture 100.

  In (e) of FIG. 4, the CPU 310 simultaneously controls the brightness of the luminaire 100 to change at a period perceived by a person. That is, the brightness of the illumination light by the lighting apparatus 100 is clearly perceived by a person. That is, the luminaire 100 illuminates inappropriately for a person to read a book. Thereby, it is possible to limit browsing over a certain time (that is, allowable time). Furthermore, since the change in the brightness of the illumination light is also perceived by the person, it makes the person feel that it is being seen by something, thus providing a crime prevention effect.

  In FIG. 4F, the motion detection unit 212 detects an operation of returning an object held by a person (here, an operation of returning a book to a bookshelf). The CPU 310 controls the lighting apparatus 100 to stop the change in brightness. In this way, if the person returns the object (returns the book to the bookshelf), the change in brightness of the illumination light inappropriate for viewing the object is stopped.

  In FIG. 4G, the motion detection unit 212 detects that a person has gone out of the imaging range. The CPU 310 always detects the movement of the person detected in (a) and excludes it from the detection target by detecting that the person has moved out of the imaging range in (g).

  In (e1) of FIG. 4, the motion detection unit 212 detects an operation of returning an object that a person has in his hand. The CPU 310 stops the measurement for a predetermined time and returns it to the normal color temperature (first color temperature) when an operation for returning an object held by a person is detected before the predetermined time elapses. The lighting apparatus 100 is controlled. As a result, the state shown in FIG. The state (f1) is the same as the state (b). In this way, lighting that makes it easy to see things, for example, lighting that is comfortable for browsing, is within a certain period of time, but if you put back what you have in your hand, you can make it easy to see things many times be able to.

[Operation]
The operation of the lighting control system according to the present embodiment configured as described above will be described below.

  FIG. 5A is a diagram illustrating a flowchart example of a lighting control process in the embodiment. FIG. 5B is a flowchart illustrating a continuation of FIG. 5A. FIG. 5C is a diagram illustrating another example of the flowchart of FIG. 5A.

  In FIG. 5A, when the motion detection unit 212 detects that a person has entered the imaging range of the imaging device 200 (Yes in S51), the CPU 310 of the control device 300 that has received the detection result activates a lighting processing program. Thus, the lighting control process is started (S52). In FIG. 5A, the lighting control process is activated for each person who has entered the imaging range.

  In the lighting control procedure of FIG. 5B, first, the control device 300 determines whether or not the person has left the imaging range based on the detection result of the motion detection unit 212. When it is determined that the person has left the imaging range (yes in S500), the control device 300 ends the lighting control procedure corresponding to the person. When it is determined that the person is not out of the imaging range (no in S500), the control device 300 further determines whether or not the movement detecting unit 212 has detected an action in which the person picks up an object. Control device 300 returns to Step S500, when the operation which a person picks up an object is not detected (it is no at S501).

  In addition, when the control device 300 detects an action of a person picking up an object (Yes in S501), the control device 300 selects the lighting apparatus 100 that illuminates the person and the object by referring to the arrangement data 32, and selects the lighting device 100. The color temperature of the lighting apparatus 100 is increased (S502). At this time, the illumination light of the selected luminaire 100 is increased from the first color temperature to the second color temperature. Furthermore, the control device 300 starts measuring a certain time by the timer unit 314 (S503). At this time, when the person picks up the object, the color temperature increases from the first color temperature to the second color temperature, so that the object can be easily seen. In other words, it makes browsing easier.

  Furthermore, based on the detection result of the motion detection unit 212, the control device 300 determines whether or not the person is holding the object in his / her hand (that is, whether or not the user is browsing).

  The control apparatus 300 returns to the process of S504, when browsing and it does not elapse for a fixed time (yes in S504, no in S505). When a predetermined time is exceeded during browsing, the control device 300 controls the brightness of the selected lighting apparatus 100 to change at a period perceived by a person (S506). Then, the lighting apparatus 100 is controlled so as to restore the illumination light, that is, to restore the second color temperature to the first color temperature (normal color temperature) (S507). In this way, after a certain period of time, the same comfort as browsing during a certain period of time is lost. In addition, it has the effect of preventing book shoplifting due to changes in color temperature.

  In the case of no in step S504 described above, that is, when a person stops browsing before a predetermined time elapses, the process of FIG. 5C is performed. As shown in the figure, based on the detection result of the motion detection unit 212, the control device 300 determines whether the person has returned the object (S511), whether the person has left the imaging range (S512), It is determined whether or not the person has hidden the object (S513).

  As a result of these determinations, when the person returns the object, exits the imaging range, or does not hide the object, the control device 300 ends the time measurement by the time measuring unit 314 for a predetermined time. (S515), the lighting apparatus 100 is controlled to return the illumination light of the lighting apparatus 100 from the second color temperature to the first color temperature (normal color temperature) (S516), and the process returns to A. When the person hides the object, the control device 300 notifies the external device or a specific person (for example, a security guard) of the situation as a predetermined process (S514), and then performs step S515, S516 is performed. In this way, lighting that makes it easy to see things (for example, lighting that is comfortable for browsing) is within a certain range of time, but if you put back what you have in your hand, you can make lighting that makes things easy to see any number of times. Can be possible. Further, when a person hides an object, the control device 300 notifies the above to prevent crime.

  In addition, after step S507 described above (at this time, the person is browsing for a certain period of time), the control device 300 further checks that the person is browsing based on the detection result of the motion detection unit 212. It is determined whether or not there is (S508). In the case of no in step S508, that is, when the person stops browsing after a certain time has elapsed, the processing of FIG. 5D is performed. As shown in the figure, the control device 300 determines whether the person has returned the object based on the detection result of the motion detection unit 212 (S521), whether the person has left the imaging range (S522), It is determined whether or not the person has hidden the object (S523). As a result of these determinations, when the person returns the object, leaves the imaging range, or does not hide the object, the control device 300 can be perceived by the person with respect to the lighting device 100. The lighting apparatus 100 is controlled so as to stop the periodic change in brightness (S525), and the process returns to A. In addition, when the person hides the object, the control device 300 notifies the external device or a specific person (for example, a guard) of the situation as a predetermined process (S524), and then performs step S525. Do. In this way, when a person returns the object (for example, returns a book to the bookshelf) after a certain period of time has elapsed, the change in brightness of the illumination light unsuitable for viewing the object is stopped. Further, when a person hides an object, the control device 300 notifies the above to prevent crime.

  Note that step S506 may be omitted. Even when omitted, the comfort of standing-by reading can be reduced by returning the color temperature to the original in step S507.

  In steps S514 and S524, a predetermined process other than notification may be performed. The predetermined process may be, for example, a predetermined sound output (for example, “we are working on strengthening crime prevention in our shop”) that causes the lighting apparatus 100 to flash vigorously at a period that can be perceived by a person.

  Further, between steps S512 and S515 and between S522 and S525, the control device 300 may add a process for notifying the situation. This notification notifies an external device or a specific person that the imaging range has been reached by holding a book. In this way, for example, the number of people who go to the cash register with a book and the number of books can be predicted in advance.

[Other configuration examples]
Next, another configuration example of the lighting control system will be described. FIG. 6 is a block diagram illustrating another configuration example of the lighting control system according to the embodiment. 1 is different from FIG. 1 in that the motion detection unit 212 is provided in the control device 300 instead of the imaging device 200. Hereinafter, different points will be mainly described.

  In FIG. 1, each of the plurality of imaging devices 200 includes a motion detection unit 212. In this case, the motion detection unit 212 and the imaging device 200 correspond one-to-one, and a human motion can be detected independently for each imaging device 200. The configuration of FIG. 1 is suitable when the number of imaging devices 200 is large.

  In contrast, in FIG. 6, the control device 300 includes a motion detection unit 212. In this way, the motion detection unit 212 can be one in the control device 300. This configuration is suitable when the processing capability of the motion detection unit 212 is high or when the number of the imaging devices 200 is not large.

  In the above embodiment, the imaging device 200 may be included in the lighting fixture 100. In this case, the imaging range only needs to include the illumination area, and the imaging range and the illumination area may correspond to each other on a one-to-one basis.

  As described above, the lighting control system according to Embodiment 1 includes at least one lighting fixture 100, an imaging device 200 that images people and objects in the illumination area of the at least one lighting fixture, and a person from an image of the imaging device. A motion detection unit 212 that detects the movement of the object, and a control device 300 that controls at least one lighting device. When the motion detection unit 212 detects that the person picks up the object, the control device 300 receives the illumination light from at least one lighting device 100. The lighting device 100 is controlled so that the color temperature of the illumination light is set to a second color temperature higher than the normal first color temperature, and the illumination is performed when the continuation of the state exceeds a certain time. First with respect to instrument 100 Control back to the color temperature.

  According to this, when a person picks up an object, the color temperature increases from the first color temperature to the second color temperature, so that the object can be easily seen. Furthermore, since the person who picked up the object feels as if he / she has seen his / her movement due to the change of the color temperature, the crime prevention effect of preventing shoplifting can be obtained.

  Here, the thing is a book, and the motion detection unit 212 may detect that the person picks up the book from the bookshelf, and may detect that the book is opened and held in the hand as a state.

  According to this, in a bookstore, a person starts reading while holding a book, and within a certain time range, the book is illuminated at the second color temperature so that the reading can be made comfortable. The same comfort as browsing within a certain period of time is lost. Furthermore, it has the effect of preventing book shoplifting due to changes in color temperature.

  Here, when the continuation of the state exceeds a certain time, the control device 300 may further control the brightness of the luminaire 100 to change at a period perceived by a person.

  According to this, it is possible to make it difficult to read over a predetermined time.

  Here, the motion detection unit 212 detects an operation of returning an object that a person has in his / her hand, and the control device 300 is constant after the motion detection unit 212 detects an operation of the person picking up an object. When the operation of returning an object held by a person to the original is detected before the passage of time, the lighting device 100 may stop measuring for a certain period of time.

  According to this, lighting that makes it easy to see things, for example, lighting that is comfortable for browsing, is within a certain range of time, but if you put back what you have in your hand, you can make it easy to see things many times Can be.

  Here, the motion detection unit 212 detects an operation of returning an object that a person has in his / her hand, and the control device 300 is constant after the motion detection unit 212 detects an operation of the person picking up an object. When the operation of returning the object held by the person after the time is detected, the lighting apparatus 100 may be controlled to stop the change in brightness.

  According to this, if the person returns the object, for example, if the book is returned to the bookcase, the change in brightness of the illumination light that is not suitable for seeing the object is stopped.

  Here, the control device 300 has a time measuring unit 314 that measures a certain time, the state continues within a certain time, and the motion detection unit 212 is an operation in which another person picks up another object. May be restarted when the timer 314 detects a certain time.

  According to this, when a plurality of people sequentially pick up an object within the illumination area of one lighting fixture, the measurement for a certain period of time started first is canceled, and finally the person picks up the object sequentially. The measurement of a certain time that is sometimes activated becomes effective.
