(First embodiment)
A first embodiment of the present invention will now be described with reference to the drawings.
FIG. 1 is a system configuration diagram showing an example of the configuration of an imaging system SYS according to a first embodiment of the present invention.
The photographing system SYS is a system for photographing a subject. Specifically, the photographing system includes at least a plurality of lights used for photographing the subject and an imaging device used for photographing the subject, and the photographing system specifies the illumination luminance of each of the plurality of lights and the photographing parameters of the imaging device according to the material of the subject, sets the photographing parameters in the imaging device, and sets each illumination luminance for each of the plurality of lights.

More specifically, the photography system SYS of the present invention includes a photography device 100, a user terminal device 200, and a photography box B.
The photographing device 100 and the user terminal device 200 are connected to each other via a network so as to be able to communicate with each other. The photographing device 100 and each device in the photographing box B are connected to each other so as to be able to communicate with each other via wired or wireless communication.

The user terminal device 200 receives input of selection information representing the material of the subject from the user. The user terminal device 200 outputs the received selection information to the image capture device 100. The user terminal device 200 obtains output information from the image capture device 100, including a captured image of the subject captured using setting information corresponding to the material represented by the selection information.

Here, the captured image may be either a still image or a moving image, but we will explain the case of a still image as an example.

The material of the subject here is the material of the object that will be the subject, such as marble, film prints, paper prints, wood, glass, ceramics, paintings, jewelry, metal, rooms, wallpaper, etc. Note that the material of the subject may be a combination of multiple types of materials, such as a main material and a secondary material.

The setting information is information that corresponds to each material of the subject, such as the lighting luminance parameters of each of the multiple lights used to photograph the subject, shooting parameters such as the shutter speed, F-number, ISO sensitivity, and focal length of the imaging device used to photograph the subject, and parameters for the angle of the shooting stand on which the subject is placed when photographing the subject.

The multiple lights may be one or more LED lights, one or more strobe lights, or other lights. Each light may have a diffusion plate disposed in front of the light projection surface to generate diffused light.

The image capturing device 100 identifies setting information such as image capturing parameters and lighting brightness according to the material of the subject. The image capturing device 100 sets the identified setting information in each of the multiple lights and the image capturing device. The image capturing device 100 uses the setting information to capture the subject and obtain a captured image. The image capturing device 100 generates output information including the captured image and outputs it to the user terminal device 200.

The photographing box B is a photographing box used for photographing a subject. The photographing box B preferably has a sealed structure with high light-blocking properties, but is not limited to this.
Inside the shooting box B, a subject H, an imaging device C, a plurality of lights L, and a base D are arranged.

The subject H is an object to be photographed by the imaging device C.
The imaging device C is an imaging device that captures an image of a subject. The imaging device C is, for example, a digital camera, a video camera, etc. The imaging device C outputs an image of the subject captured by the imaging device 100. Here, the imaging parameters of the imaging device C are set by the imaging device 100, and the imaging of the subject is controlled by the imaging device 100.

The multiple lights L are lighting devices that are arranged so that they can project light onto the subject. For example, the multiple lights L are lights L1, L2, L3, L4, etc. Each of the multiple lights L has at least adjustable lighting intensity. The lighting intensity of each of the multiple lights L is controlled by the imaging device 100. Note that the multiple lights L may have adjustable light projection angles, may be arranged in multiple vertical and horizontal directions so that they can project light onto the subject, and it may be possible to adjust which of the lights to use, or a combination of lighting intensity, projection angle, which light to use, etc. may be adjustable.

The base D is a support base on which a subject is placed. The base D is composed of an imaging base D1 and support legs D2. The imaging base D1 is supported by the support legs D2. The angle of the imaging base D1 relative to the horizontal plane and the angle relative to the vertical plane are adjustable. The angle of the imaging base D1 is controlled by the imaging device 100. The imaging base D1 may be rotatable in the vertical axis direction or may be fixed.

Next, the configuration of the imaging device 100 will be described.

FIG. 2 is a block diagram showing an example of the configuration of the imaging device 100 according to this embodiment.
The photographing device 100 includes a communication unit 11 , a storage unit 12 , an input unit 13 , an output unit 14 , and a control unit 15 .
The communication unit 11 has a function of communicating with the user terminal device 200 via a network. The communication unit 11 also has a function of communicating with each device in the photography box B that is connected via a wired or wireless connection.

The storage unit 12 is configured with a storage medium, for example, a hard disk drive (HDD), a flash memory, an electrically erasable programmable read only memory (EEPROM), a random access read/write memory (RAM), a read only memory (ROM), or any combination of these storage media.
The storage unit 12 may be, for example, a non-volatile memory.

The storage unit 12 stores various data. For example, the storage unit 12 stores setting information 121.
The setting information 121 is information that associates, for each material of the subject, parameters of the lighting luminance of each of the multiple lights L used to photograph the subject, shooting parameters such as the shutter speed, F-number, ISO sensitivity, and focal length of the imaging device C used to photograph the subject, and parameters such as the angle of the pedestal D on which the subject is placed when photographing the subject.

The input unit 13 is an input device such as a mouse or a keyboard that is connected to the imaging device 100. The input unit 13 accepts operation input input from the outside. The input unit 13 outputs an operation signal corresponding to the operation input to the control unit 15.

The output unit 14 is an output device such as a display device. The output unit 14 outputs the presentation information and output information output from the control unit 15 to the output device or to another device such as the user terminal device 200.

The control unit 15 has a function of controlling each unit of the imaging device 100 .
The control unit 15 includes a presentation unit 151 , a material information acquisition unit 152 , a setting change unit 153 , an imaging control unit 154 , an image acquisition unit 155 , an output information generation unit 156 , and an operation reception unit 157 .

The presentation unit 151 generates presentation information. For example, the presentation information is a message to the user encouraging the user to place the subject on the pedestal. Furthermore, the presentation unit 151 acquires initial setting information from the storage unit 12 based on the subject being placed on the pedestal. The presentation unit 151 outputs the acquired initial setting information to the setting change unit 153.
The presentation unit 151 generates selection information that is presented to the user so that the user can select which of multiple candidates the material of the subject is. The presentation unit 151 outputs presentation information including the captured image input from the image acquisition unit 155 and the selection information to the output unit 14.

The material information acquisition unit 152 acquires material information representing a material selected by the user from among candidate material candidates for the subject presented to the user as presentation information. The material information acquisition unit 152 acquires setting information corresponding to the material indicated by the material information from the storage unit 12 based on the material information or an instruction signal. The material information acquisition unit 152 outputs the setting information corresponding to the acquired material to the setting change unit 153.

When setting information for the initial settings is input, the setting change unit 153 sets the initial settings for each of the multiple lighting devices, the imaging device, and the base. The setting change unit 153 outputs a completion signal indicating that the settings have been completed to the imaging control unit 154. Furthermore, when setting information corresponding to a material is input, the setting change unit 153 sets the setting information corresponding to the material for each of the multiple lighting devices, the imaging device, and the base. The setting change unit 153 outputs a completion signal indicating that the settings have been completed to the imaging control unit 154.

When the completion signal is input, the imaging control unit 154 controls the imaging device, each of the multiple lights, and the base to capture an image of the subject.

The image acquisition unit 155 acquires a photographed image of the subject captured by the imaging device C. If the photographed image of the subject is a photographed image captured using the initial setting information (also referred to as a first photographed image), the image acquisition unit 155 outputs the photographed image to the presentation unit 151. Furthermore, if the photographed image is a photographed image captured using setting information corresponding to the material (also referred to as a second photographed image), the image acquisition unit 155 outputs the photographed image of the subject to the output information generation unit 156.

When the captured image (second captured image) is input, the output information generating unit 156 generates output information including the captured image. For example, the output information generating unit 156 generates the output information by changing the captured image (first captured image) in the presentation information to the input captured image (second captured image).

The output information may include an operator that allows the user to adjust and select parameters of the setting information, an operator that can instruct the user to take a photograph again, and an operator that can instruct the user to complete photographing. When generating output information including a photographed image, the output information generating unit 156 may perform color conversion processing according to the characteristics of the destination medium. In this case, for example, if the color characteristics of the destination medium are stored in a format such as an ICC Profile, color conversion processing can be performed by converting the color space of the photographed image into the color space of the destination medium. In this way, the user can accurately check the color of the subject to be photographed in accordance with the output medium.

The operation acceptance unit 157 accepts user operations on the output information. Based on the operation of an operator that allows the user to select parameters of the setting information so that they can be adjusted, the operation acceptance unit 157 outputs the parameters of the setting information corresponding to the operation to the setting change unit 153, and sets the parameters of the setting information to one or more of the imaging device, each of the multiple lights, and the base. Furthermore, based on the operation of an operator that can instruct reshooting, the operation acceptance unit 157 outputs an instruction signal to the material information acquisition unit 152. Furthermore, based on the operation of an operator that can instruct completion of shooting, the operation acceptance unit 157 ends the shooting process.

Next, we will explain the setting information stored in the memory unit 12 of the imaging device 100.

FIG. 3 is a diagram showing an example of the setting information 121 stored in the storage unit 12 of the imaging device 100 according to this embodiment.
The setting information is information in which a lighting condition ID, a shooting setting ID, and a shooting stand setting ID are associated with each material. The material represents the material of an object such as a subject. The lighting condition ID is identification information for identifying a parameter of lighting intensity. The shooting setting ID is identification information for identifying a shooting parameter. The shooting stand setting ID is identification information for identifying an angle parameter of the stand.

For example, in the example shown in the second row, the "material" is "marble", the "lighting condition ID" is "1", the "photography setting ID" is "1", and the "photography stand setting ID" is "1".
Also, for example, in the example shown in the third row, the item is “material”, “film print”, the “lighting condition ID” is “2”, the “shooting setting ID” is “2”, and the “shooting stand setting ID” is “2”.
In this way, the setting information is a parameter set associated with each material.
The setting information may include parameters for each piece of equipment used to photograph the subject, in addition to the parameters for the lighting, the stand, and the imaging device.

Fig. 4 is a diagram showing another example of the setting information stored in the storage unit 12 of the imaging device 100 according to the present embodiment. Specifically, Fig. 4 is a diagram showing an example of a parameter of illumination intensity included in the setting information.
The illumination intensity parameter is information in which each of a plurality of illuminations is associated with each illumination intensity for each of the plurality of illuminations for each illumination condition ID. The illumination condition ID corresponds to the illumination condition ID included in the setting information shown in FIG.
As shown in the figure, the lighting intensity parameter is a parameter that allows the lighting intensity for each of the multiple lights to be set according to the lighting condition ID. Note that the lighting intensity "L1" in the example shown in the figure represents, for example, the lighting intensity set for the lighting L1 in FIG.

Fig. 5 is a diagram showing an example of setting information stored in the storage unit 12 of the imaging device 100 according to this embodiment. Specifically, Fig. 5 shows an example of imaging parameters of the imaging device included in the setting information.
The shooting parameters are information in which the setting values of the shutter speed, the F-number, the ISO sensitivity, and the focal length are associated with each shooting setting ID. The shooting setting ID corresponds to the shooting setting ID included in the setting information shown in FIG.

Fig. 6 is a diagram showing an example of setting information stored in the storage unit 12 of the imaging device 100 according to this embodiment. Specifically, Fig. 6 shows an example of a pedestal angle parameter included in the setting information.
The angle parameter is information in which the setting values of the angle (vertical) and the angle (horizontal) are associated with each imaging stand setting ID. The imaging stand setting ID corresponds to the imaging stand setting ID included in the setting information shown in FIG.

As shown in Figures 3, 4, 5, and 6, the setting information specifies the lighting intensity, shooting parameters, angle parameters, etc. that correspond to the material of the object that is the subject.

Next, we will explain the shooting process in the shooting system SYS according to this embodiment.

FIG. 7 is a flowchart showing an example of the photographing process in the photographing system SYS according to the present embodiment.
In step S101, the image capture device 100 generates and outputs presentation information, which is a message that prompts the user to place a subject on a pedestal. After that, the image capture device 100 generates and presents selection information for allowing the user to select a material for the subject based on the fact that the subject has been placed on the pedestal. After that, the image capture device 100 executes the process of step S102.

In step S102, the image capture device 100 acquires initial setting information from the storage unit 12 based on the fact that the subject has been placed on the pedestal, and sets the initial setting information in each piece of image capture equipment. After that, the image capture device 100 executes the process of step S103.

In step S103, the image capture device 100 acquires a first captured image of a subject using the pedestal, lighting, and image capture device that are set using the initial setting information. The first captured image is also called a preview image. After that, the image capture device 100 executes the process of step S104.

In step S104, the image capturing device 100 presents the presentation information including the first captured image and the selection information to the user as an output display. Then, the process of step S105 is executed.

In step S105, the image capture device 100 accepts a user operation on the output display and determines whether a completion operation has been performed. If a completion operation has been performed by the user (step S105 YES), that is, if the user has determined that the quality of the first captured image is sufficient, the image capture device 100 ends the image capture process shown in FIG. 7. On the other hand, if a completion operation has not been performed by the user (step S105 NO), that is, if the user has determined that the quality of the first captured image is not sufficient, the image capture device 100 executes the process of step S106.

In step S106, the image capture device 100 acquires material information in response to a user operation on the presented information. After that, the image capture device 100 executes the process of step S107.

In step S107, the image capture device 100 acquires setting information corresponding to the material information from the storage unit 12, and sets each parameter corresponding to the setting information for each piece of image capture equipment. After that, the image capture device 100 executes the process of step S103.

Next, we will explain an example of the output display.

FIG. 8 is a diagram showing an example of an output display output by the imaging device 100 according to this embodiment.
The illustrated example is an example in which presentation information including a first captured image and selection information is output and displayed.
In the illustrated example, the captured image is an area in which a first captured image is displayed. The first image captured by the imaging device is displayed in this area.
In the illustrated example, "Select material:" is an area in which selection information is displayed in a selectable manner, for example, in a pull-down format. When the user selects a material of the subject in this area, material information corresponding to the selection is output to the image capture device 100.
In the illustrated example, "change lighting" is an area for adjusting setting information by the user. For example, an operator for instructing to change lighting is displayed in this area, and the user operates the operator to, for example, increase or decrease the lighting intensity.
In the illustrated example, "Shoot" and "Complete" are areas that display operators. The operators are an operator for instructing shooting of a second captured image that is shot using setting information corresponding to the material of the selected subject, and an operator for instructing completion of shooting of the subject. By operating either of the operators, the user can select whether to shoot the captured image again or to end shooting.

In this way, the photography system SYS according to this embodiment is a photography system SYS that includes at least a plurality of lights L used to photograph a subject and an imaging device C used to photograph the subject, and is equipped with an identification unit (material information acquisition unit 152) that identifies the lighting luminance of each of the plurality of lights L and the photography parameters of the imaging device C according to the material of the subject, and a setting unit (setting change unit 153) that sets the photography parameters to the imaging device C and sets each lighting luminance to each of the plurality of lights L (L1, L2, L3, L4, L5, L6, L7, etc.).

In this way, the photography system SYS can improve the convenience of the user when photographing a subject. More specifically, the photography system SYS can acquire a photographed image in which setting information for photographing the subject according to the material information is set. This makes it possible, for example, to perform photography in a remote location and acquire a photographed image of a certain quality according to the material regardless of the photographer.

(Second embodiment)

Next, a second embodiment will be described.
In the second embodiment, an example will be described in which the image capturing apparatus 100 acquires material information by estimating the material of a subject, instead of acquiring material information according to selection information in the first embodiment.
In the second embodiment, the differences from the first embodiment will be mainly described, and the description of the other parts will be omitted by citing the description of the first embodiment.

FIG. 9 is a block diagram showing an example of the configuration of an imaging device 100 according to the second embodiment of the present invention.
The imaging device 100 includes a communication unit 11, a storage unit 12, an input unit 13, an output unit 14, and a control unit 15. The control unit 15 includes a presentation unit 151, a setting change unit 153, an imaging control unit 154, an image acquisition unit 155, an output information generation unit 156, an operation acceptance unit 157, and a material estimation unit 158.

The material estimation unit 158 estimates the material of the object in the first captured image of the subject captured based on the initial setting information, for example, by using a learning model based on AI or machine learning. The material estimation unit 158 acquires setting information corresponding to the estimated material from the storage unit 12. The material estimation unit 158 outputs the setting information corresponding to the estimated material to the setting change unit 153.

The learning model may be a model generated by learning the correspondence between the material of a subject and a photographed image of the subject. For example, by inputting a photographed image of a subject into the learning model, the material of the subject is output as material information. The AI may estimate the material of the subject based on, for example, the similarity of the photographed images, the glossiness, reflection, and unevenness of the subject in the photographed image, etc.

Next, we will explain the shooting process in the shooting system SYS according to this embodiment.

FIG. 10 is a flowchart showing an example of the photographing process in the photographing system SYS according to the present embodiment.
In step S201, the image capturing apparatus 100 generates and outputs presentation information, which is a message prompting the user to place the subject on the pedestal, to the user. After that, the image capturing apparatus 100 executes the process of step S202.

In step S202, the image capture device 100 acquires initial setting information from the storage unit 12 based on the fact that the subject has been placed on the pedestal, and sets the initial setting information in each piece of image capture equipment. After that, the image capture device 100 executes the process of step S203.

In step S203, the image capture device 100 acquires a first captured image of a subject using the pedestal, lighting, and image capture device that are set using the initial setting information. The first captured image is also called a preview image. After that, the image capture device 100 executes the process of step S204.

In step S204, the image capture device 100 estimates the material of the subject in the first captured image using AI, a learning model, or the like. Then, the process of step S205 is executed.

In step S105, the image capture device 100 acquires setting information corresponding to the estimated material information from the storage unit 12, and sets each parameter corresponding to the setting information for each piece of image capture equipment. The image capture device 100 generates a second captured image of the subject captured using the setting information corresponding to the material information. After that, the image capture device 100 executes the process of step S206.

In step S206, the image capture device 100 presents the second captured image and presentation information including selection information that allows the user to adjust the material to the user as an output display. Then, the image capture process in FIG. 10 ends.

In this way, the photography system SYS according to this embodiment is a photography system SYS that includes at least a plurality of lights L used to photograph a subject and an imaging device C used to photograph the subject, and is equipped with an identification unit (material information acquisition unit 152) that identifies the lighting luminance of each of the plurality of lights L and the photography parameters of the imaging device C according to the material of the subject, and a setting unit (setting change unit 153) that sets the photography parameters to the imaging device C and sets each lighting luminance to each of the plurality of lights L (L1, L2, L3, L4, L5, L6, L7, etc.).

In this way, the photography system SYS can improve the convenience of the user when photographing a subject. More specifically, the photography system SYS can acquire a photographed image in which setting information for photographing the subject according to the material information is set. This makes it possible, for example, to perform photography in a remote location and acquire a photographed image of a certain quality according to the material regardless of the photographer.

The photography system SYS further includes a material estimation unit 158 that estimates the material of the subject from a first photographed image of the subject, and an output unit 14 that outputs a second photographed image photographed using the settings.

In this way, by setting the subject on a pedestal, it is possible to obtain an image of the subject photographed with settings suitable for the estimated material.

(Third embodiment)

Next, a third embodiment will be described.
In the third embodiment, an example of a case where a rendering pattern according to a material is selected in the first embodiment will be described.
In the third embodiment, the difference from the first embodiment will be mainly described. For the other parts, the description of the first embodiment will be used and the description will be omitted. In the present embodiment, the case where the performance pattern in the first embodiment is used will be described, but the performance pattern in the second embodiment may be used.

The photographing device 100 includes a communication unit 11, a storage unit 12, an input unit 13, an output unit 14, and a control unit 15. The storage unit 12 stores setting information. The setting information is information in which a rendering setting, a lighting condition ID, a photographing setting ID, a photographing stand setting ID, and the like are associated with each material. The rendering setting is setting information for a plurality of rendering patterns for each material. The rendering patterns are settings for emphasizing the characteristics of a material, such as unevenness, flatness, transparency, three-dimensionality, gloss, and non-gloss.
Description will be given with reference to FIG.

FIG. 11 is a diagram showing an example of setting information stored in a storage unit of an imaging apparatus according to the third embodiment of the present invention.
The setting information is information in which a production setting, a lighting condition ID, a shooting setting ID, and a shooting stand setting ID are associated with each material.

For example, in the example shown in the second row, the "material" is "painting," the "performance setting" is "texture," the "lighting condition ID" is "1," the "shooting setting ID" is "1," and the "shooting stand setting ID" is "1."
Also, for example, in the example shown in the third row, the "material" is "painting", the "shooting setting" is "flatness", the "lighting condition ID" is "2", the "shooting setting ID" is "2", and the "shooting stand setting ID" is "2".

In this way, multiple presentation patterns are provided for one material, and lighting conditions, shooting settings, and shooting stand settings are prepared according to each presentation pattern. In this way, it is possible to generate a photographed image that further emphasizes the texture of the subject.

Next, we will explain the shooting process in the shooting system SYS according to this embodiment.

FIG. 12 is a flowchart showing an example of the photographing process in the photographing system SYS according to the present embodiment.
In step S301, the image capture device 100 generates and outputs presentation information, which is a message that prompts the user to place a subject on a pedestal. After that, the image capture device 100 generates and presents selection information for allowing the user to select a material for the subject based on the fact that the subject has been placed on the pedestal. After that, the image capture device 100 executes the process of step S302.

In step S302, the image capture device 100 acquires initial setting information from the storage unit 12 based on the fact that the subject has been placed on the pedestal, and sets the initial setting information in each piece of image capture equipment. After that, the image capture device 100 executes the process of step S303.

The first captured image is also called a preview image. After that, the image capture device 100 executes the process of step S304.

In step S304, the image capturing device 100 presents the presentation information including the first captured image and the selection information to the user as an output display. Then, the process of step S305 is executed.

In step S305, the image capture device 100 accepts a user operation on the output display and determines whether a completion operation has been performed. If a completion operation has been performed by the user (step S305 YES), that is, if the user has determined that the quality of the first captured image is sufficient, the image capture device 100 ends the image capture process shown in FIG. 12. On the other hand, if a completion operation has not been performed by the user (step S305 NO), that is, if the user has determined that the quality of the first captured image is not sufficient, the image capture device 100 executes the process of step S306.

In step S306, the image capture device 100 acquires material information in response to a user operation on the presented information. After that, the image capture device 100 executes the process of step S307.

In step S307, the image capture device 100 acquires setting information corresponding to the user's selection of material information and effect patterns from the storage unit 12, and sets each parameter corresponding to the setting information for each piece of image capture equipment. After that, the image capture device 100 executes the process of step S303.

Next, we will explain an example of the output display.

FIG. 13 is a diagram showing an example of an output display output by the imaging device 100 according to this embodiment.
The illustrated example is an example in which presentation information including a first captured image and selection information is output and displayed.
In the illustrated example, the "captured image" is an area in which a captured image such as a first captured image, a second captured image, etc. The first image captured by the imaging device is displayed in this area.
In the illustrated example, "Select material:" is an area in which selection information is displayed in a selectable manner, for example, in a pull-down format. When the user selects a material of the subject in this area, material information corresponding to the selection is output to the image capture device 100.
In the illustrated example, "Select a performance:" is an area in which performance patterns (performance settings) corresponding to the material are displayed in a selectable manner, for example, in a pull-down format. When the user selects a performance pattern corresponding to the material of the subject in this area, the performance pattern corresponding to the selection is output to the image capture device 100.
In the illustrated example, "change lighting" is an area for adjusting setting information by the user. For example, an operator for instructing to change lighting is displayed in this area, and the user operates the operator to, for example, increase or decrease the lighting intensity.
In the illustrated example, "Shoot" and "Complete" are areas that display operators. The operators are an operator for instructing shooting of a second captured image that is shot using setting information corresponding to the material of the selected subject, and an operator for instructing completion of shooting of the subject. By operating either of the operators, the user can select whether to shoot the captured image again or to end shooting.

In this way, the photography system SYS according to this embodiment is a photography system SYS that includes at least a plurality of lights L used to photograph a subject and an imaging device C used to photograph the subject, and is equipped with an identification unit (material information acquisition unit 152) that identifies the lighting luminance of each of the plurality of lights L and the photography parameters of the imaging device C according to the material of the subject, and a setting unit (setting change unit 153) that sets the photography parameters in the imaging device C and sets each lighting luminance to each of the plurality of lights L (L1, L2, L3, L4, L5, L6, L7, etc.).

In this way, the photography system SYS can improve the convenience of the user when photographing a subject. More specifically, the photography system SYS can acquire a photographed image in which setting information for photographing the subject according to the material information is set. This makes it possible, for example, to perform photography in a remote location and acquire a photographed image of a certain quality according to the material regardless of the photographer.

In addition, in the above-mentioned photography system SYS, the identification unit (material information acquisition unit 152) further identifies a photography effect presentation pattern according to the material of the subject, and the setting unit (setting change unit 153) sets the photography parameters and the respective lighting brightness according to the photography effect presentation pattern.

In this way, a captured image of the subject can be generated using setting information that further emphasizes the texture of the material.
