In the present embodiment, the terminal devices 5 and 6 are personal computers used by the user who uses the lighting space simulation device 1, respectively. The user operates the terminal device 5 or 6 to use the lighting space simulation device 1 via the Internet 4.

Next, a specific configuration of the lighting space simulation device 1 will be described.

FIG. 2 is a block diagram showing a characteristic functional configuration of the lighting space simulation device 1 according to the embodiment. As shown in FIG. 2, the illumination space simulation device 1 includes an input unit 10, a storage unit 14, a display unit 16, a communication unit 17, and a control unit 11.

The input unit 10 is a device that acquires a user's instruction. That is, the lighting space simulation device 1 may directly acquire instructions such as simulation conditions from the input unit 10 without going through the Internet 4. The input unit 10 is, but is not limited to, a keyboard or a touch panel as long as it can acquire an instruction from the user.

The storage unit 14 is a memory that stores the illumination space information 15 and the like required when the control unit 11 (specifically, the simulation unit 13 described later) performs a simulation. The storage unit 14 is composed of, for example, a ROM (Read Only Memory), a RAM (Random Access Memory), an HDD (Hard Disk Drive), or the like.

The illumination space information 15 is data used by the simulation unit 13 when performing a simulation. The lighting space information 15 is data for specifying a lighting space indicating a space such as a cafe or a hotel, for example. The data for specifying the illumination space includes not only image data displayed in two dimensions but also data indicating a three-dimensional space. The data for specifying the illumination space is, for example, data processed by CG (Computer Graphics).

The display unit 16 is a display that displays information or the like received from the control unit 11 (specifically, the dialogue unit 12 described later) as an image.

The communication unit 17 is a communication interface that connects the lighting space simulation device 1 and the LAN 2 (see FIG. 1) connected to the Internet 4.

The control unit 11 is a processing unit that performs a simulation according to a condition instructed by the user and controls to generate and output an image according to the simulation result. The control unit 11 is realized by, for example, a CPU (Central Processing Unit) and a control program stored in the storage unit 14. The control unit 11 is functionally composed of a dialogue unit 12 and a simulation unit 13.

The dialogue unit 12 is a GUI (Graphical User Interface), and is a processing unit that acquires an instruction for specifying at least one of the illumination light and the illumination space from the user. Further, when the instruction acquired from the user is an instruction to perform a simulation, the dialogue unit 12 causes the simulation unit 13 to perform a simulation according to the instruction. Further, the dialogue unit 12 controls to acquire the simulation result performed by the simulation unit 13 and generate and display an image according to the simulation result. Specifically, the dialogue unit 12 controls the display of the image on the terminal devices 5 and 6 used by the user or the display unit 16 of the lighting space simulation device 1.

The simulation unit 13 is a processing unit that performs simulation according to the simulation conditions from the user acquired by the dialogue unit 12.

The dialogue unit 12 and the simulation unit 13 are realized by, for example, a CPU and a control program stored in the storage unit 14. The dialogue unit 12 and the simulation unit 13 may be configured as one unit or as separate bodies, and are not limited.

Further, the user can confirm the simulation result in the lighting space desired by the user by operating the terminal devices 5 and 6 or the lighting space simulation device 1, but the device operated by the user is as described above. , Not limited. In the following description, it is assumed that the user operates the terminal device 5 and uses the lighting space simulation device 1 via the Internet 4. That is, the dialogue unit 12 controls to acquire an instruction from the user from the terminal device 5 operated by the user via the Internet 4, generate an image according to the instruction, and display it on the terminal device 5. To do.

Next, the details of the dialogue unit 12 and the simulation unit 13 will be described.

The dialogue unit 12 obtains an instruction from the user to identify at least one of the illumination light and the illumination space. The instruction for specifying the illumination light is an instruction for specifying the color temperature and the color deviation of the illumination light.

Here, the color temperature is a light color emitted from a blackbody (an object that completely absorbs and emits light incident from the outside over all wavelengths) at a predetermined temperature. It is the corresponding numerical value. The higher the color temperature, the more bluish the light color, and the lower the color temperature, the reddish the light color. The unit of color temperature is expressed in K (Kelvin). Further, the color deviation (Duv) represents a deviation from the chromaticity indicating the color temperature on the blackbody locus in the chromaticity diagram defined by the CIE (International Commission on Illumination). When the Duv shifts to the plus side, it shifts to the lower side of the blackbody locus in the chromaticity diagram, and the light color becomes purplish. Further, when the Duv shifts to the minus side, it shifts to the upper side of the blackbody locus in the chromaticity diagram, and the light color becomes greenish. That is, even if the color temperature is the same (correlated color temperature), the light color is different if the color deviation is different. In other words, by expressing the color of the illumination light using the color temperature and the color deviation, it is possible to express a color (chromaticity) that is not on the blackbody locus. The simulation unit 13 can simulate an illumination space illuminated by illumination light that emits a light color having a color temperature and a color deviation specified by the user. By doing so, the user can confirm the hue of the illumination space illuminated by the illumination light of the desired color.

Further, the instruction for specifying the illumination light may also include an instruction regarding dimming and toning of the illumination light. For example, the dialogue unit 12 obtains an instruction of the brightness of the illumination light from the user. The simulation unit 13 simulates the brightness of the entire lighting space in response to the instruction.

Further, the instruction for specifying the illumination light may include an instruction for specifying a plurality of illumination lights. For example, when a plurality of lighting devices are installed in a lighting space, instructions of the color temperature and color deviation of the lighting light emitted by the lighting device are obtained from the user for each lighting device.

Further, the plurality of illumination lights include the illumination light in the indirect illumination by the reflected light obtained by irradiating the structure including the ceiling and the wall with the light from the light source (illumination device), and the direct illumination space by the light of the light source. Illumination light in the main lighting is included. That is, the simulation unit 13 performs the simulation by changing the characteristics such as the light reflectance of the ceiling and the wall of the illumination space. Further, the simulation unit 13 includes the color temperature and color deviation (color adjustment) of the illumination light, the light intensity (dimming) of the illumination light, and the illumination for each lighting device that emits indirect lighting or main illumination arranged in the illumination space. An instruction such as the direction in which light is emitted (light distribution) is acquired from the user and a simulation is performed.

Further, the dialogue unit 12 controls to display the illumination space having the hue calculated by the simulation unit 13. Specifically, the dialogue unit 12 controls the terminal device 5 used by the user to display an illumination space having a hue calculated by the simulation unit 13.

Further, the dialogue unit 12 controls a superposed display in which the display of a plurality of types of lighting spaces to be selected is superimposed on a part of the display of the lighting space having the hue calculated by the simulation unit 13. Further, when the dialogue unit 12 obtains an instruction from the user to select one lighting space from a plurality of types of lighting spaces, the dialogue unit 12 displays a superimposed display reflecting the hue obtained by the simulation unit 13 for the selected lighting space. Take control.

Further, the dialogue unit 12 is separated by using a partition line for the illumination space having the hue calculated by the simulation unit 13 when two sets of instructions are obtained from the user regarding the color temperature and the color deviation of the illumination light. Controls the two-part display that displays the two spaces. Specifically, for the above two spaces, one is displayed with the hue obtained corresponding to the illumination light of the color temperature and the color deviation of one of the above two sets, and the other is of the two sets. It controls the two-division display that displays in the hue obtained corresponding to the illumination light of the other color temperature and color deviation. Further, when the dialogue unit 12 acquires an instruction to move the position of the partition line from the user, the dialogue unit 12 controls the two-division display while moving the position of the partition line according to the acquired instruction.

Further, when an instruction regarding zoom is acquired from the user, the dialogue unit 12 controls to zoom and display the illumination space according to the acquired instruction. For example, the user indicates a predetermined range in the lighting space displayed on the terminal device 5. The dialogue unit 12 acquires the predetermined range from the user, and controls to superimpose and display the enlarged image of the range on the image in which the illumination space is displayed.

Further, the dialogue unit 12 acquires an instruction of the color of the article existing in the lighting space from the user. For example, when a car, which is an example of the article, is displayed in the lighting space, the user indicates the color of the car. The dialogue unit 12 acquires the instruction. The simulation unit 13 changes the color of the automobile in response to the instruction, and then simulates the hue when the automobile is irradiated with the illumination light.

In addition, the dialogue unit 12 acquires an instruction from the user to specify the position of the viewpoint in the lighting space. As described above, the data for specifying the illumination space may be not only the image data displayed in two dimensions but also the data indicating the three-dimensional space. For example, the dialogue unit 12 controls the terminal device 5 to display a three-dimensional lighting space. The user confirms the lighting space on the terminal device 5 and instructs a position (viewpoint) and a direction (visual field range) in the lighting space. The dialogue unit 12 acquires the instruction of the position and the direction, and generates an image of the illumination space when the direction is viewed from the position.

The simulation unit 13 simulates the hue of the illumination space according to the instruction from the user acquired by the dialogue unit 12. Specifically, the simulation unit 13 is a lighting space in which the entire lighting space specified by the user is uniformly illuminated by the illumination light of the color temperature and the color deviation specified by the user acquired by the dialogue unit 12. The hue is calculated by simulation.

It should be noted that at least one of the illumination light and the illumination space may be specified as the instruction acquired from the user. For example, it is assumed that the instruction from the user acquired by the dialogue unit 12 specifies the color temperature and color deviation of the illumination light, and does not specify the illumination space. In this case, the simulation unit 13 arbitrarily selects one from a plurality of information indicating the illumination space, which is an example of the illumination space information 15 stored in the storage unit 14, and the color temperature of the illumination light of the instruction. And the color deviation may be used for the simulation. The method by which the simulation unit 13 arbitrarily selects the illumination space is not particularly limited, but may follow the selection method predetermined in the storage unit 14. For example, the illumination space may be selected according to the color temperature and color deviation specified by the user. Further, for example, it is assumed that the instruction from the user acquired by the dialogue unit 12 specifies the illumination space and does not specify the color temperature and the color deviation of the illumination light. In this case, the dialogue unit 12 acquires the color temperature and the color deviation predetermined in the storage unit 14. The simulation unit 13 may perform the simulation in the illumination space specified by the user by using the illumination light of the color temperature and the color deviation acquired by the dialogue unit 12.

Here, a specific example of the simulation method performed by the simulation unit 13 will be described. First, a CG, which is a two-dimensional or three-dimensional illumination space in which the color of each pixel is specified, is created in advance and stored in the storage unit 14. Next, according to the user's instruction, an illumination space having a hue when the illumination space is illuminated with illumination light having a predetermined color temperature and a predetermined color deviation is created.

For example, suppose that the dialogue unit 12 obtains an instruction from the user indicating a light color having a color temperature of 4000 K and a color deviation of Duv + 3. The simulation unit 13 calculates the hue of the illumination space, assuming that the illumination light of the light color having a color temperature of 4000K and a color deviation of Duv + 3 is uniformly irradiated to the entire illumination space. Specifically, the simulation unit 13 changes the color of each pixel in the illumination space according to the light color of the illumination light. By doing so, the simulation unit 13 determines the hue of the illumination space when the illumination light having a color temperature of 4000 K and a color deviation of Duv + 3 is uniformly irradiated to the entire illumination space.

In CG indicating a three-dimensional illumination space, it is sufficient that the chromaticity is set as a portion where the illumination light is illuminated only on the outer surface of a structure such as a wall or ceiling and an article such as an automobile.

Further, the simulation unit 13 calculates the hue of the illumination space assuming that the illumination light of a predetermined light color is uniformly irradiated to the entire illumination space, but the present invention is not limited to this. For example, it is assumed that a lighting device that emits illumination light is arranged in the illumination space. In that case, the light intensity (light intensity) and light distribution of the illumination light emitted by the lighting device are set in advance. In addition, the light reflectance of structures such as walls and ceilings is also set in advance. When the dialogue unit 12 receives an instruction of the color temperature and the color deviation of the illumination light from the user, the simulation unit 13 simulates the light color of the illumination light emitted by the illumination device with the instructed color temperature and the color deviation. By doing so, the user can confirm the color tone of the entire illumination space illuminated by the illumination light emitted by the illumination device.

Further, the simulation unit 13 simulates one lighting space selected from a plurality of types of lighting spaces according to the instructions acquired by the dialogue unit 12. For example, the lighting space may be the lighting space information 15 stored in the storage unit 14, or may be the lighting space acquired from the user.

Further, as described above, the simulation unit 13 mainly illuminates the illumination space by the illumination light in the indirect illumination by the reflected light obtained by irradiating the structure including the ceiling and the wall with the light from the light source and the light of the light source. Perform a simulation using the illumination light in the lighting. That is, the simulation unit 13 performs the simulation by reflecting the light reflectance and the like preset on the ceiling, the wall, and the like of the illumination space. Further, when the dialogue unit 12 obtains an instruction of the color temperature and the color deviation of the illumination light from the user for each lighting device that emits indirect lighting or main lighting, the simulation unit 13 responds to the instruction for each lighting device. Perform the simulation under the above conditions.

Next, the basic flow of operations of the dialogue unit 12 and the simulation unit 13 will be described.

FIG. 3 is a flowchart showing a basic operation procedure of the lighting space simulation by the lighting space simulation device 1 according to the embodiment.

First, the dialogue unit 12 generates an image for acquiring an instruction for specifying at least one of the illumination light and the illumination space from the user, and controls the display of the image (S10). For example, the dialogue unit 12 generates a plurality of images showing the lighting space in order to allow the user to select the lighting space, and controls the terminal device 5 used by the user to display the plurality of images. Further, the dialogue unit 12 generates an image for instructing the user of the color temperature and the color deviation indicating the hue of the illumination space, and displays the image on the terminal device 5.

Next, the dialogue unit 12 acquires an instruction from the user (S11). For example, the user selects one image showing the lighting space from the plurality of images showing the lighting space generated in step S10. Further, the user selects a set of color temperature and color deviation from the image for instructing the user of the color temperature and color deviation indicating the hue of the illumination space generated in step S10. The dialogue unit 12 acquires the lighting space selected by the user and the color temperature and color deviation instructions.

Next, when the simulation unit 13 acquires an instruction to perform the simulation from the user in the dialogue unit 12 (“simulation” in S12), the simulation unit 13 performs the simulation according to the instruction (S13). For example, the simulation unit 13 simulates the hue of the illumination space when the illumination space selected by the user is irradiated with illumination light having a color temperature and a color deviation selected by the user. The dialogue unit 12 generates an image (illumination space image) showing the result of the simulation performed by the simulation unit 13 and controls the display of the image. Specifically, the dialogue unit 12 controls to display the image on the terminal device 5 operated by the user (S10).

Further, when the instruction from the user acquired by the dialogue unit 12 is not an instruction for which simulation needs to be performed (“other” in S12), the dialogue unit 12 executes the process according to the instruction (S14). For example, when the dialogue unit 12 acquires an instruction regarding zoom from the user, it controls to zoom and display the illumination space according to the acquired instruction. Specifically, the dialogue unit 12 controls to generate an image in which the zoomed range is enlarged according to the instruction of the zoomed range included in the instruction acquired from the user and display it on the terminal device 5.

As described above, the dialogue unit 12 acquires an instruction from the user (S11). Next, the dialogue unit 12 determines the instruction content of the instruction (S12). Next, the dialogue unit 12 or the simulation unit 13 performs processing according to the determined instruction content (S13 or S14). Next, the dialogue unit 12 controls to generate and display an image according to the processing performed in step S13 or step S14 (S10). In this way, the dialogue unit 12 and the simulation unit 13 repeat the operations of steps S10 to S14 described above. When an instruction to end the use of the illumination space simulation device 1 is obtained from the user (“end” in S12), the dialogue unit 12 ends the operation.

Next, a specific example of the illumination space image to be displayed on the terminal device 5 operated by the user by the dialogue unit 12 will be described with reference to FIGS. 4 to 13. As described above, the dialogue unit 12 controls to generate an image according to an instruction from the user and display the image.

FIG. 4 is a diagram showing a specific example of an image generated by the lighting space simulation device 1 according to the embodiment, which allows the user to select a lighting space. When the lighting space simulation device 1 acquires an instruction to use the lighting space simulation device 1 from the user, the lighting space simulation device 1 first generates the lighting space selection image 211 shown in FIG. 4 and controls the display of the lighting space selection image 211. ..

As shown in FIG. 4, the illumination space selection image 211 includes a plurality of images (illumination spaces 212 to 216) showing the illumination space. The dialogue unit 12 acquires data indicating the lighting spaces 212 to 216, which is an example of the lighting space information 15 stored in the storage unit 14, from the storage unit 14, and generates a lighting space selection image 211 including the lighting spaces 212 to 216. To do. Although the illumination space selection image 211 does not display an image for allowing the user to select the color temperature and the color deviation, the dialogue unit 12 generates an image for allowing the user to select the color temperature and the color deviation. You may control the display. FIG. 4 is an image showing illumination spaces 212 to 216 when the entire illumination spaces 212 to 216 are uniformly illuminated by illumination light having a predetermined color temperature and color deviation. The user selects one lighting space from the lighting spaces 212 to 216 included in the lighting space selection image 211 displayed on the terminal device 5. The dialogue unit 12 acquires the selection as an instruction from the user.

FIG. 5 is a diagram showing a specific example of an illumination space image generated by the illumination space simulation apparatus 1 according to the embodiment. Specifically, FIG. 5 is an image generated by the dialogue unit 12 when the user selects the illumination space 212 in FIG.

The simulation unit 13 simulates the hue of the illumination space when illuminated by illumination light having a predetermined color temperature and color deviation in the illumination space specified by the user from the illumination spaces 212 to 216 shown in FIG. .. The dialogue unit 12 controls to generate a display image 400 including an illumination space image 100 showing the result of the simulation and display it on the terminal device 5.

As shown in FIG. 5, the display image 400, which is an image generated by the dialogue unit 12, is composed of an illumination space image 100 and a simulation condition selection unit 200.

The illumination space image 100 is an image showing the hue of the illumination space when the illumination space selected by the user is illuminated with illumination light having a predetermined color temperature and a predetermined color deviation. When the dialogue unit 12 has acquired an instruction of a predetermined color temperature and a predetermined color deviation from the user, the predetermined color temperature and the predetermined color deviation are the color temperature and the color deviation of the instruction. When the dialogue unit 12 has not obtained the instruction of the predetermined color temperature and the predetermined color deviation from the user, the predetermined color temperature and the predetermined color deviation are the predetermined color temperature and the color deviation. In the present embodiment, as an example, when the user selects the illumination space 212, the dialogue unit 12 is illuminated by the illumination space 212 having a color temperature of 4000 K and a color deviation of Duv + 3. Is generated as the illumination space image 100.

The illumination space simulation device 1 stores data indicating the hue of the illumination space when the illumination space is irradiated with illumination light having a predetermined color temperature and a predetermined color deviation as illumination space information 15 in advance in the storage unit 14. You may hold it. In that case, the simulation unit 13 may acquire data (illumination space information 15) according to the instruction from the storage unit 14 in response to the instruction from the user. In that case, the dialogue unit 12 may control to generate an image (illumination space image 100) corresponding to the data (illumination space information 15) and display the image on the terminal device 5.

The simulation condition selection unit 200 is an image selected when the user wants to change the simulation conditions performed by the simulation unit 13. The simulation condition selection unit 200 includes a lighting space selection unit 210, an interior material selection unit 220, a light color selection unit 230, a display mode selection unit 240, a comparison image selection unit 250, an image storage selection unit 260, and illumination. It is composed of a sample order selection unit 270.

The illumination space selection unit 210 is an image selected when the user wants to change the illumination space.

The interior material selection unit 220 is an image selected when the user wants to change the texture of the structure 320 such as the wall W or the ceiling C of the space displayed in the lighting space. Here, the texture refers to characteristics such as the shape, light absorption rate, and light reflectance of the material constituting the wall W or ceiling C or the like. For example, when the material of the structure 320 is concrete or wood, the light reflectance of the illumination light is different when the illumination light is irradiated. Therefore, by changing the texture of the structure 320, when the entire illumination space is irradiated with the illumination light, the color tone of the entire illumination space changes. Further, not only the texture of the structure 320 but also the color of the article A may be changed.

The light color selection unit 230 is an image selected when the user wants to change the color temperature and color deviation of the illumination light applied to the illumination space. Further, the light color selection unit 230 is an image selected by the user when he / she wants to simulate an illumination space in which the light colors of the indirect illumination 310 and the main illumination 300 are changed.

The display mode selection unit 240 is an image selected when the user wants to change the display method of the illumination space image 100. For example, when the user wants to change the color temperature and the color deviation of the illumination light emitted from the right half and the left half of the illumination space image 100 shown in FIG. 5, the user selects the display mode selection unit 240.
