(Embodiment)

  The illumination space simulation apparatus 1 is a Web server that acquires an instruction of simulation conditions such as illumination space or color information from a user who uses the terminal devices 5 and 6, and performs simulation of the illumination space according to the instruction. Here, the color information is information indicating a predetermined color temperature and a predetermined color deviation. That is, the illumination space simulation device 1 simulates the hue of the illumination space when the entire illumination space is illuminated by the illumination device that emits light of a light color having a predetermined color temperature and a predetermined color deviation. Has characteristics.

  The router 3 functions as a gateway that interconnects the LAN 2 and the Internet 4.

  The terminal devices 5 and 6 are computers as Web clients that give various instructions to the lighting space simulation device 1 or perform data transmission / reception. In the present embodiment, each of the terminal devices 5 and 6 is a personal computer used by a user who uses the illumination space simulation device 1. 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 illumination space simulation apparatus 1 will be described.

  FIG. 2 is a block diagram showing a characteristic functional configuration of the illumination space simulation apparatus 1 according to the embodiment. As illustrated 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 user instructions. That is, the illumination space simulation apparatus 1 may acquire an instruction such as a simulation condition directly from the input unit 10 without using the Internet 4. Although the input part 10 should just acquire the instruction | indication from a user and is not limited, For example, it is a keyboard or a touch panel.

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

  The illumination space information 15 is data used when the simulation unit 13 performs a simulation. The illumination space information 15 is data for specifying an illumination space indicating a space such as a cafe or a hotel, for example. The data 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 received from the control unit 11 (specifically, a dialogue unit 12 described later) as an image.

  The communication unit 17 is a communication interface that connects the illumination 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 control according to a condition instructed by the user, and performs control 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 includes a dialogue unit 12 and a simulation unit 13 as functions.

  The interaction unit 12 is a GUI (Graphical User Interface), and is a processing unit that acquires an instruction for specifying at least one of illumination light and illumination space from a user. In addition, 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 performs control to acquire a simulation result performed by the simulation unit 13 and generate and display an image corresponding to the simulation result. Specifically, the dialogue unit 12 controls the terminal device 5 or 6 used by the user or the display unit 16 of the illumination space simulation device 1 to display the image.

  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 a single unit or may be configured as separate bodies, and are not limited.

  Moreover, the user can confirm the simulation result in the illumination space desired by the user by operating the terminal devices 5 and 6 or the illumination 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 illumination space simulation device 1 via the Internet 4. That is, the dialogue unit 12 performs control to acquire an instruction from the user from the terminal device 5 operated by the user via the Internet 4, generate an image corresponding to the instruction, and display the image on the terminal device 5. To do.

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

  The dialogue unit 12 acquires an instruction for specifying at least one of the illumination light and the illumination space from the user. 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 refers to the color of light to be expressed as the color of light emitted from a black body (an object that completely absorbs and emits light incident from the outside over all wavelengths) at a predetermined temperature. This is the corresponding number. The light color becomes bluish as the color temperature is high, and the light color is red as the color temperature is low. The unit of color temperature is expressed in K (Kelvin). The color deviation (Duv) represents a deviation from the chromaticity indicating the color temperature on the black body locus in the chromaticity diagram defined by the CIE (International Commission on Illumination). When Duv shifts to the plus side, it shifts to the lower side of the black body locus in the chromaticity diagram, and the light color becomes purplish. Further, when Duv is shifted to the minus side, in the chromaticity diagram, it shifts to the upper side of the black body locus, and the light color is tinged with green. That is, even at the same color temperature (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, a color (chromaticity) that is not on the black body locus can be expressed. The simulation unit 13 can simulate an illumination space illuminated with 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 with the illumination light of the desired color.

  In addition, the instruction for specifying the illumination light may include an instruction regarding light adjustment and color adjustment of the illumination light. For example, the dialogue unit 12 acquires an instruction on the brightness of the illumination light from the user. The simulation unit 13 simulates the brightness of the entire illumination space according to the instruction.

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

  The plurality of illumination lights directly illuminate the illumination space with the illumination light in the indirect illumination by the reflected light obtained by applying the light from the light source (illuminating device) to the structure including the ceiling and the wall, and the light of the light source. The illumination light in the main illumination is included. That is, the simulation unit 13 performs simulation by changing characteristics such as light reflectance of the ceiling and walls of the illumination space. Furthermore, the simulation unit 13 is configured so that the color temperature and color deviation (toning) of the illumination light, the light intensity (dimming) of the illumination light, the illumination for each illumination device that emits indirect illumination or main illumination arranged in the illumination space. An instruction such as the direction in which light is emitted (light distribution) is obtained from the user and a simulation is performed.

  In addition, the dialogue unit 12 performs control to display an illumination space having a 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.

  In addition, the dialogue unit 12 controls superposition display in which a plurality of types of illumination spaces to be selected are superimposed on a part of the display of the illumination space having the hue calculated by the simulation unit 13. When the dialogue unit 12 obtains an instruction to select one illumination space from a plurality of types of illumination spaces from the user, the dialogue unit 12 displays a superimposed display that reflects the hue obtained by the simulation unit 13 for the selected illumination space. Take control.

  The dialogue unit 12 separates the illumination space having the hue calculated by the simulation unit 13 using a partition line when the two sets of instructions are obtained from the user regarding the color temperature and the color deviation of the illumination light. The two-division display for displaying the two spaces is controlled. Specifically, with respect to the two spaces, one of the two sets is displayed with a hue obtained corresponding to illumination light having one color temperature and color deviation, and the other of the two sets is displayed. Control of two-division display is performed to display with a hue obtained corresponding to the illumination light of the other color temperature and color deviation. In addition, 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 zooming 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 instructs a predetermined range in the illumination space displayed on the terminal device 5. The dialogue unit 12 obtains the predetermined range from the user and performs control to superimpose and display an enlarged image of the range on the image in which the illumination space is displayed.

  In addition, the dialogue unit 12 obtains an instruction for the color of the article existing in the illumination space from the user. For example, when a car that is an example of the article is displayed in the illumination space, the user instructs the color of the car. The dialogue unit 12 acquires the instruction. The simulation unit 13 changes the color of the automobile according to the instruction, and then simulates the hue when the automobile is irradiated with illumination light.

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

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

  In addition, the instruction | indication acquired from a user should just specify at least one of illumination light and illumination space. 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 out of a plurality of pieces of information indicating an illumination space that 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 It is also possible to perform a simulation with color deviation. The method for arbitrarily selecting the illumination space by the simulation unit 13 is not particularly limited, but may be performed according to a 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. 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 color deviation of the illumination light. In this case, the dialogue unit 12 acquires a color temperature and a color deviation that are predetermined in the storage unit 14. The simulation unit 13 may perform a simulation in an illumination space instructed by the user using the illumination light having the color temperature and the color deviation acquired by the dialogue unit 12.

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

  For example, it is assumed that the dialogue unit 12 obtains an instruction indicating a light color having a color temperature of 4000 K and a color deviation of Duv + 3 from the user. The simulation unit 13 calculates the hue of the illumination space on the assumption that the illumination light of the light color having a color temperature of 4000K and the color deviation of Duv + 3 is uniformly applied 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 color of the illumination space when the illumination light having a color temperature of 4000 K and a color deviation of Duv + 3 is uniformly applied to the entire illumination space.

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

  Moreover, although the simulation part 13 calculated the hue of the said illumination space supposing that the illumination light of a predetermined | prescribed light color was uniformly irradiated to the whole illumination space, it is not restricted to this. For example, it is assumed that an illumination device that emits illumination light is disposed in the illumination space. In that case, the light intensity (light quantity) and light distribution of the illumination light emitted from the illumination device are set in advance. Further, the light reflectance of a structure such as a wall or a ceiling is also set in advance. When the dialogue unit 12 receives an instruction of the color temperature and 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 color deviation. By doing so, the user can confirm the hue of the entire illumination space illuminated by the illumination light emitted by the illumination device.

  In addition, the simulation unit 13 performs simulation for one illumination space selected from a plurality of types of illumination spaces in accordance with the instruction acquired by the dialogue unit 12. For example, the illumination space may be the illumination space information 15 stored in the storage unit 14 or an illumination space acquired from the user.

  Further, as described above, the simulation unit 13 illuminates the illumination space directly with the illumination light in the indirect illumination by the reflected light obtained by applying the light from the light source to the structure including the ceiling and the wall, and the light of the light source. A simulation using illumination light is performed. That is, the simulation unit 13 performs simulation by reflecting light reflectance and the like set in advance on the ceiling and walls of the illumination space. Furthermore, when the dialogue unit 12 obtains an instruction of the color temperature and color deviation of the illumination light for each illumination device that emits indirect illumination or main illumination from the user, the simulation unit 13 responds to the instruction for each illumination device. The simulation is performed under the specified conditions.

  Next, a 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 illumination space simulation by the illumination space simulation apparatus 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 to display the image (S10). For example, the dialogue unit 12 performs control for generating a plurality of images indicating the illumination space and causing the terminal device 5 used by the user to display the plurality of images in order to allow the user to select the illumination space. Further, the dialogue unit 12 generates an image for instructing the user of the color temperature and the color deviation indicating the color 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 indicating the illumination space from a plurality of images indicating the illumination space generated in step S10. Further, the user selects one set of color temperature and color deviation from the image for instructing the user of the color temperature and color deviation indicating the color of the illumination space generated in step S10. The dialogue unit 12 acquires an instruction of the illumination space selected by the user, the color temperature, and the color deviation.

  Next, when the simulation unit 13 obtains an instruction to perform a simulation from the user (“simulation” in S12), the simulation unit 13 performs a simulation according to the instruction (S13). For example, the simulation unit 13 performs a simulation of the color 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) indicating the result of the simulation performed by the simulation unit 13 and controls to display the image. Specifically, the dialogue unit 12 performs control to display the image on the terminal device 5 operated by the user (S10).

  Further, when the instruction from the user acquired by the dialog unit 12 is not an instruction that needs to be simulated (“other” in S12), the dialog unit 12 executes a process according to the instruction (S14). For example, when the dialogue unit 12 acquires an instruction related to zooming from the user, control is performed to zoom and display the illumination space according to the acquired instruction. Specifically, the dialogue unit 12 performs control to generate an image in which the range is enlarged according to the zoom range instruction included in the instruction acquired from the user and display the image 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 performs control to generate and display an image corresponding to the processing performed in step S13 or step S14 (S10). As described above, the dialogue unit 12 and the simulation unit 13 repeat the operations in steps S10 to S14 described above. When the instruction to end the use of the lighting space simulation device 1 is acquired from the user (“End” in S12), the dialogue unit 12 ends the operation.

  Next, a specific example of an illumination space image displayed on the terminal device 5 operated by the user by the dialogue unit 12 will be described with reference to FIGS. As described above, the dialog unit 12 generates an image in accordance with an instruction from the user and performs control to display the image.

  FIG. 4 is a diagram illustrating a specific example of an image generated by the illumination space simulation apparatus 1 according to the embodiment and allowing the user to select an illumination space. When the illumination space simulation device 1 obtains an instruction to use the illumination space simulation device 1 from the user, the illumination space simulation device 1 first generates the illumination space selection image 211 shown in FIG. 4 and performs control to display the illumination space selection image 211. .

  As illustrated in FIG. 4, the illumination space selection image 211 includes a plurality of images (illumination spaces 212 to 216) indicating the illumination space. The dialogue unit 12 acquires data indicating the illumination spaces 212 to 216 that are examples of the illumination space information 15 stored in the storage unit 14 from the storage unit 14, and generates an illumination space selection image 211 including the illumination spaces 212 to 216. To do. In addition, although the image for making a user select color temperature and a color deviation is not displayed on the illumination space selection image 211, the dialogue part 12 produces | generates the image for making a user select color temperature and a color deviation. The display may be controlled. 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 illumination space from the illumination spaces 212 to 216 included in the illumination 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 illustrating 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 color of the illumination space when illuminated by illumination light having a predetermined color temperature and color deviation in the illumination space designated by the user from the illumination spaces 212 to 216 shown in FIG. . The dialogue unit 12 performs control to generate the display image 400 including the illumination space image 100 indicating the result of the simulation and to display the display image 400 on the terminal device 5.

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

  The illumination space image 100 is an image showing the color 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 acquires 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 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 a predetermined color temperature and color deviation. In the present embodiment, as an example, when the user selects the illumination space 212, the interaction unit 12 is illuminated with the illumination light 212 having a color temperature of 4000K and a color deviation of Duv + 3. Is generated as the illumination space image 100.

  Note that the illumination space simulation device 1 stores, in advance as the illumination space information 15, data indicating the color of the illumination space when illumination light having a predetermined color temperature and a predetermined color deviation is irradiated on the illumination space. You may hold. In that case, the simulation part 13 may acquire the data (illumination space information 15) according to the said instruction | indication from the memory | storage part 14 according to the instruction | indication from a user. In that case, the dialog part 12 should just perform control which produces | generates the image (illumination space image 100) according to the said data (illumination space information 15), and displays the said image on the terminal device 5. FIG.

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

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

  The interior material selection unit 220 is an image that is 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 illumination space. Here, the texture refers to characteristics such as the shape, light absorption rate, or light reflectance of the material constituting the wall W or the ceiling C. For example, when the material of the structure 320 is concrete and wood, when the illumination light is irradiated, the light reflectance of the illumination light is different.
