The terminal communication unit 50 can transmit the command information (lighting control content, terminal position and shooting direction) generated by the transmission information generation unit 35 to the server 3.

The server 3 includes a CPU 60, a memory 70, and a server communication unit 80, which are connected to each other via a system bus in such a manner that signals and data can be exchanged with each other.

The memory 70 is a storage unit that stores the ID of each of the lamps 4 and the lamp position including the latitude and longitude with respect to the ID. The memory 70 is, for example,
About lamp 4-1 ID: lamp A, latitude-longitude: 35.68-139.76
About lamp 4-2, ID: lamp B, latitude-longitude: 35.50-139.80
・ ・ ・ (Omitted for lamps 4-3 to 4-6) ・ ・ ・
About lamp 4-7, ID: lamp G, latitude-longitude: 35.40-139.95
About lamp 4-8, ID: lamp H, latitude-longitude: 35.20-140.12

Identify. Specifically, the lamp identification unit 61 is configured to specify the lamp 4 whose lamp position is included in the target region defined by a predetermined central angle centered on the shooting direction from the terminal position as the target lamp 4t. ..

FIG. 3 shows the positional relationship between the mobile terminal 2 and the lamps 4-1 to 4-8 (lamp IDs: A to H) in the shooting state of FIG. It is assumed that the terminal position of the mobile terminal 2 is latitude: 35.44 and longitude: 139.82, and the shooting direction (broken line X) is 30 ° 18'12 ". The shooting range (target area R) is defined. The shooting azimuth angle is a central angle α centered on the shooting azimuth. The central angle α is a preset angle of about several ° to several tens of degrees, and corresponds to a shooting range that can be displayed on the touch panel 20 (. It can be said that the viewing angle of the camera 10 is α).

In this example, the lamp position of the ID: lamp B is latitude-longitude: 35.50-139.80, which is included in the target area R. Therefore, the lamp identification unit 61 identifies the lamp 4-2 as the target lamp 4t corresponding to the photographing lamp 4c. The far end of the target area R may be defined by a predetermined radius (for example, a radius of about 10 m to 100 m) from the terminal position, or may be defined by grouping the lamps 4. In the latter case, for example, even if a lamp 4-x of a group different from the lamps 4-1 to 4-8 exists on the extension line of the broken line X, the lamp 4-x does not become the target lamp 4t. ..

When a plurality of lamps 4 are displayed in the image area 21, that is, when a plurality of lamps 4 are included in the target area R, the lamp specifying unit 61 identifies all of them as the target lamps 4t. Alternatively, the lamp 4 located closest to the center of the shooting azimuth angle may be specified as the target lamp 4t. Alternatively, the lamp specifying unit 61 identifies one or more lamps 4 located in the range of the central angle β (α> β) (that is, near the center of the shooting direction) with respect to the shooting direction as the target lamp 4t. May be good. In this way, by adjusting the setting of the central angle α or β of the target region R or the setting of the near end, the lamp 4 included in the appropriate range is specified as the target lamp 4t.

Alternatively, when a plurality of lamps 4 are included in the target area R, the lamp specifying unit 61 calculates the distance between the lamp position and the terminal position with respect to each of the plurality of lamps 4, and the lamp 4 having the smallest distance is calculated. That is, the lamp 4 closest to the portable terminal 2 may be specified as the target lamp 4t.

The signal generation unit 62 transmits a lighting control signal for causing the target lamp 4t (in this example, the lamp 4-2 / ID: lamp B) to execute the lighting control content included in the command information received by the server communication unit 80. Generate. Therefore, the lighting control signal includes at least the address of the target lamp 4t and the data for specifying the lighting control content. Then, the server communication unit 80 transmits the lighting control signal to the target lamp 4t.

The lamp communication unit 90 is configured to receive a lighting control signal from the server 3 via the Internet 5. The connection between the lamp communication unit 90 and the Internet 5 may be a wired connection or a wireless connection. The communication between the lamp communication unit 90 and the server communication unit 80 may be a push type (a communication method in which the server 3 actively transmits a lighting control signal to the lamp 4) or a pull type (the lamp 4 is a communication method). A communication method in which the server 3 is periodically inquired and the server 3 transmits a lighting control signal to the lamp 4) may be used.

The light source 94 includes an LED array having a plurality of light emitting color LED elements. The lighting device 92 is an LED power supply that receives an AC power supply (not shown) and controls lighting of each of a plurality of emission color LED arrays. The lighting device 92 is a rectifier circuit that rectifies the AC power supply, and a DC / DC converter that converts the rectified output of the rectifier circuit into direct current for the LED array of each color and supplies each converted direct current to the corresponding LED array. And a control circuit that controls the value of each of the direct currents based on the illumination control signal received by the lamp communication unit 90.

Summarizing the above, for example, the following operations are possible. It is assumed that the user of the mobile terminal 2 takes a picture of the lamp 4-2 with the camera 10 and touches the red icon 223 of the icon area 22 while displaying the lamp 4-2 in the image area 21. In response to this, command information indicating the terminal position, shooting direction, and red light emission is transmitted from the mobile terminal 2 to the server 3. In the server 3, the terminal position, the shooting direction, and the lamp position are inquired, the lamp 4-2 (lamp B) is specified as the target lamp 4t, and the lighting control signal for red light emission is transmitted to the lamp 4-2. Then, in the lamp 4-2, the light source 94 emits red light based on the illumination control signal.

Regarding the operation of the icon area 22, when the second light color is selected while the first light color is lit, the second light color is mixed with the first light color. The mixed color lighting may be performed, or the lighting of the first light color may be switched to the lighting of the second light color. For example, when the blue icon 224 is selected when the red lighting is performed, the lighting may be switched to the red-purple (magenta) color emission in which the red and the blue are mixed, or the red lighting may be blue. It may be switched to lighting. Moreover, not only the icon for monochromatic lighting but also the icon for other kinds of lighting may be provided.

As a result, when the user of the mobile terminal 2 shoots the lamp 4 with the camera 10 and selects the icon of the lighting control content, the shooting lamp 4c is set based on the acquired terminal position, the shooting direction, and the stored lamp position. The corresponding target lamp 4t is specified, and the lighting control content is executed in the target lamp 4t. As described above, the information that needs to be stored in advance is each lamp position (latitude and longitude) with respect to the identification of each lamp, and such information is easy to obtain and process. In addition, the user can control the lighting of the photographing lamp 4c by an intuitive operation of simply shooting the lamp 4 and selecting an icon. Therefore, in the lighting control system 1 that controls the lighting of the lamp 4 by using the mobile terminal 2, a configuration that is easy to introduce and can be operated intuitively is realized. In particular, in the present embodiment, the server 3 is provided with the memory 70 for storing the lamp position, the lamp specifying unit 61 for specifying the target lamp 4t, and the signal generating unit 62 for generating the lighting control signal, so that the server 3 is provided with a large capacity and high speed lighting. Control processing becomes possible.

Further, as described above, the present embodiment can be applied to either a normal shooting mode using a real-time image or a still image mode using a still image. In the normal shooting mode, the user can enjoy a more intuitive lighting control operation. On the other hand, in the still image mode, especially when the mobile terminal 2 is a relatively heavy terminal such as a tablet, the user picks up the mobile terminal 2 in an easy-to-hold posture after shooting, or puts the mobile terminal 2 on a table. Then, you can enjoy the illumination control scanning in a comfortable posture.

<First Embodiment, Additional Example 1>
Various additional functions can be added to the basic embodiment of the present embodiment described above. For example, it is possible to control the lighting of the lamps 4 which are distributed not only in the horizontal direction but also in the vertical direction (that is, arranged at different heights). In this case, the electronic compass 34a is composed of a 3D compass or a gyro compass, or an acceleration sensor is provided in addition to the electronic compass 34a.

In this additional embodiment, for example, a lamp 4 (including a lamp for indirect lighting) arranged on a wall surface of a building, a high object, or the like is photographed, specified, and controlled. In this case, three-dimensional positioning is performed by the positioning means 33a composed of GPS, and the position acquisition unit 33 acquires the altitude in addition to the latitude and longitude of the mobile terminal 2. That is, the terminal position is defined by the latitude, longitude and altitude of the mobile terminal 2. Further, the azimuth acquisition unit 34 acquires a shooting elevation / depression angle (that is, an elevation angle or a depression angle) in addition to the shooting direction of the camera 10 by the electronic compass 34a. Therefore, the command information generation unit 35 generates command information including the terminal position, the shooting direction, the shooting elevation / depression angle, and the lighting control content. Further, the lamp position of each lamp 4 is also defined by its latitude, longitude and altitude, and these are stored in the memory 70.

Then, the lamp specifying unit 61 identifies the lamp 4 whose lamp position is included in the conical or polygonal pyramid-shaped target region extending from the terminal position in the shooting axis direction defined by the shooting direction and the shooting elevation / depression angle as the target lamp 4t. .. For example, the target area may be a conical space extending from the terminal position at a predetermined central angle γ about the shooting axis direction. Alternatively, the target area is a square cone defined by a central angle α (or β) in the plane direction from the terminal position in the plane direction with the shooting direction as the center and in the vertical direction centered on the shooting elevation / depression angle direction with a predetermined angle width δ. It may be a shaped space. Further, the far end of these target areas can also be defined in the same manner as in the above embodiment. With the configuration of this additional embodiment, various lighting controls can be realized by three-dimensionally specifying the position of the lamp.

<First Embodiment, Additional Example 2>
FIG. 5 is a block diagram of the lighting control system 1 according to the additional embodiment 2 in which the additional function is added to the basic embodiment. In this additional embodiment, the same configurations as those of the embodiment shown in FIG. 1 are designated by the same reference numerals, and the duplicated description thereof will be omitted.

As shown in FIG. 5, the CPU 30 of the mobile terminal 2 further includes an additional information processing unit 36 and an operation information output unit 37. Further, the CPU 60 of the server 3 further includes a control limiting unit 63.

The additional information processing unit 36 can acquire additional information regarding the target lamp 4t specified by the lamp specifying unit 61 and output the additional information to the touch panel 20. The additional information may include the lamp ID of the target lamp 4t, and information on the irradiation target (object, etc.) of the target lamp 4t, if any. Further, when the lamp 4 is installed in a building or an object, the additional information may include information on the building or the object itself. These additional information can be acquired from the memory 70 of the server 3 or the Internet 5. Further, as will be described later, when it is identified that the target lamp 4t is controllable or uncontrollable, that fact may be included in the additional information. For example, as shown in FIG. 6, as additional information, "lamp B control OK" or the like may be displayed with respect to the image of the lamp 4-2 in the image area 21. In this way, AR (Augmented Reality), that is, augmented reality, improves the information and operability in lighting control.

When any icon is touch-operated, the operation information output unit 37 visually expresses the operation performed on the icon area 22 (in other words, the control based on the touch operation proceeds. (Display indicating that the inside is inside) is output to the touch panel 20. For example, the operation information output unit 37 may blink or highlight the touched icon, or may output an animation extending from the touched icon toward the image of the lamp. The approximate position of the lamp image (the image position of the light source), which is the end point of the animation, can be specified as the brightest region in the image. In the example shown in FIG. 6, on the touch panel 20, a wedge-shaped pattern is displayed that advances from the vicinity of the icon 224 toward the lamp (light source) image unit in response to the touch operation of the icon 224. Such an animation is not limited to the one shown in the figure. Various modes can be adopted, such as those running on the image section. This improves operability and entertainment in lighting control.

The control limiting unit 63 limits the lighting control of the lamp 4 by the user. For example, when the target lamp 4t specified by the lamp specifying unit 61 is already controlled by another user, the control limiting unit 63 may prohibit new lighting control on the target lamp 4t. Further, the control limiting unit 63 may prohibit the lighting control of the lamp 4 outside the predetermined time. For example, lighting control in the daytime may be prohibited in consideration of energy saving, or lighting control in the midnight time may be prohibited in consideration of security, noise, and the like. When the lighting control is prohibited in this way, the control limiting unit 63 stops the generation of the lighting control signal by the signal generating unit 62. This improves the manageability of the lighting control system 1.

Further, when the lighting control is prohibited by the control limiting unit 63 in this way, as described above, a notification indicating that the target lamp 4t cannot be controlled is transmitted from the server 3 to the mobile terminal 2 as additional information. The fact may be displayed on the touch panel 20. This prevents the user from performing unnecessary operations thereafter. On the contrary, when there is no prohibited operation by the control limiting unit 63, a notification indicating that the target lamp 4t can be controlled is transmitted from the server 3 to the mobile terminal 2 as additional information, and a notification to that effect is displayed on the touch panel 20. It may be done (see FIG. 6).

Further, the control limiting unit 63 may adjust the central angle α (or the center β, the central angle γ, or the angle width δ) that defines the target region R according to the transmission frequency of the illumination control signal. For example, as the frequency of transmission of the lighting control signal increases (that is, in response to a relatively large number of users trying to control the lamps 4-1 to 4-n), the control limiting unit 63 sets the central angle α. (Or the center β, the central angle γ, or the angle width δ) may be narrowed. Further, the control limiting unit 63 may adjust the far end of the target region R according to the transmission frequency of the illumination control signal. For example, as the frequency of transmission of the lighting control signal increases, the control limiting unit 63 may bring the far end of the target area R closer to the terminal position. In this way, by narrowing the target area R when the user operation is congested, more users can enjoy the lighting control.

It is assumed that the application for executing the present embodiment is already installed in the memory 40 from the Internet 5. The memory 40 stores the correspondence between the ID of each lamp 4 and the lamp position consisting of the latitude and longitude of each lamp 4. However, from the viewpoint of the processing capacity of the CPU 30 and the storage capacity of the memory 40, the memory 40 may store a part of the data of the lamp 4 stored in the memory 70 of the first embodiment. For example, the memory 40 includes a lamp 4 installed in an area (a specific prefecture, city, ward, etc.) in which the user of the mobile terminal 2 lives, and a lamp installed in a specific facility (park, etc.) used by the user. The data of 4 can be stored.

The lamp 4 included in the target area R is specified as the target lamp 4t by reference.
In step S260, the signal generation unit 62 generates a lighting control signal for causing the target lighting equipment 4t to execute the lighting control content included in the command information, and the terminal communication unit 50 transmits this lighting control signal to the target lighting equipment 4t. ..

Steps S400 and S405 in the lamp 4 are the same as the processes in the first embodiment. That is, in step S400, the illumination control signal is received, and in step S405, the light source 94 is lighting-controlled based on the illumination control signal.

FIG. 8B shows a flowchart illustrating the operation of the lighting control system 1A in the still image mode.

That is, when the application is started in step S200, the icon is output to the touch panel 20 in step S205, and a still image is taken (step S230, Yes), the still image of the lamp tool 4 taken is the image area in step S235. It is displayed on 21. In step S236, the terminal position at the time of shooting is acquired, and in step S237, the shooting direction at the time of shooting is acquired. When the touch operation to the icon is not performed (step S240, No) and when the display of the still image is completed (step S241, Yes), the process returns to step S230 and the touch operation to the icon is not performed. If (step S240, No) and the display of the still image is not completed (step S241, No), the process returns to step S240. When the touch operation to the icon is performed (step S240, Yes), the lighting control content is determined according to the touch operation in step S245.

Steps S255 and S260 and steps S400 and S405 are the same as the processes shown in FIG. 8A. That is, in step S255, the lamp 4 included in the target region R is specified as the target lamp 4t, and in step S260, the lighting control signal is generated and transmitted to the target lamp 4t. Then, in the lamp 4, the illumination control signal is received in step S400, and the light source 94 is lighting-controlled based on the illumination control signal in step S405.

As described above, in the lighting control system 1A according to the present embodiment, the mobile terminal 2 outputs a camera 10, a touch panel 20 on which the shooting lamp 4c is displayed, and an icon indicating a lighting control option to the touch panel 20.
