According to the present invention, a technology for easily performing various evaluations regarding ultraviolet protective agents is realized.

<First embodiment>
"overview"
An overview of the evaluation device of this embodiment will be explained. As shown in FIG. 1, the evaluation device 10 of this embodiment is a server 1. The evaluation device 10 cooperates with the user terminal 20 to provide a service (hereinafter sometimes referred to as "evaluation service") that performs various evaluations regarding ultraviolet protective agents and provides the results. Various evaluations include coating unevenness evaluation and performance evaluation of the UV protection agent. For example, a user can use the evaluation service to check whether the ultraviolet protective agent has been properly applied (that is, whether there is any uneven application). Additionally, the user can use the evaluation service to check the performance of a given UV protection agent.

The user uses an ultraviolet camera to photograph his or her face, etc., coated with an ultraviolet protection agent. The user then transmits the ultraviolet image generated by the ultraviolet camera to the evaluation device 10 via the user terminal 20. The evaluation device 10 performs the various evaluations described above based on the received ultraviolet image, and transmits the evaluation results to the user terminal 20.

By the way, when ultraviolet rays are irradiated onto an object on which a coating film of an ultraviolet protective agent is placed, as shown in FIG. After entering the protective agent, specularly reflected light (2) that is specularly reflected on the surface of the object and components of internally scattered light that are scattered inside the object may be generated. The above three components may be included in the ultraviolet image taken of the object. The evaluation device 10 of this embodiment performs various evaluations such as coating unevenness evaluation and performance evaluation based on the intensity of internally scattered light, and specular reflection light (1) and specular reflection light (2) are unnecessary. It becomes a component. Therefore, the evaluation device 10 removes the specularly reflected light (1) and specularly reflected light (2) components from the ultraviolet image using a learning model prepared in advance, and the ultraviolet image after removing these components. The above various evaluations will be made based on the above.

According to a system including such a processing device 10 and a user terminal 20, a user can easily perform various evaluations regarding ultraviolet protective agents.

"Hardware configuration"
Next, an example of the hardware configuration of the evaluation device 10 will be explained. Each functional unit of the evaluation device 10 includes a CPU (Central Processing Unit) of an arbitrary computer, a memory, a program loaded into the memory, and a storage unit such as a hard disk that stores the program (which is stored in advance from the stage of shipping the device). (In addition to programs downloaded from recording media such as CDs (Compact Discs) or servers on the Internet, it is also possible to store programs downloaded from storage media such as CDs (Compact Discs) or servers on the Internet. Ru. It will be understood by those skilled in the art that there are various modifications to the implementation method and device.

FIG. 3 is a block diagram illustrating the hardware configuration of the evaluation device 10. As shown in FIG. 3, the evaluation device 10 includes a processor 1A, a memory 2A, an input/output interface 3A, a peripheral circuit 4A, and a bus 5A. The peripheral circuit 4A includes various modules. The evaluation device 10 does not need to have the peripheral circuit 4A. Note that the evaluation device 10 may be composed of a plurality of physically and/or logically separated devices. In this case, each of the plurality of devices can include the above hardware configuration.

The bus 5A is a data transmission path through which the processor 1A, memory 2A, peripheral circuit 4A, and input/output interface 3A exchange data with each other. The processor 1A is, for example, an arithmetic processing device such as a CPU or a GPU (Graphics Processing Unit). The memory 2A is, for example, a RAM (Random Access Memory) or a ROM (Read Only Memory). The input/output interface 3A is an interface for acquiring information from an input device, an external device, an external server, an external sensor, a camera (normal camera, ultraviolet camera, etc.), and an interface for acquiring information from an output device, an external device, an external server, etc. Contains interfaces for outputting. Input devices include, for example, a keyboard, mouse, microphone, physical button, touch panel, and the like. The output device is, for example, a display, speaker, printer, or the like. The processor 1A can issue commands to each module and perform calculations based on the results of those calculations.

"Functional configuration"
Next, the functional configuration of the evaluation device 10 of this embodiment will be explained in detail. FIG. 4 shows an example of a functional block diagram of the evaluation device 10. As illustrated, the evaluation device 10 includes an acquisition section 11, an image processing section 12, an evaluation section 13, and an output section 14.

The acquisition unit 11 acquires an ultraviolet image of an object on which a coating film of an ultraviolet protective agent is disposed. The acquisition unit 11 acquires an ultraviolet image transmitted by a user of the above-mentioned evaluation service using the user terminal 20. Note that in the evaluation service, the user does not need to perform an operation to remove the specularly reflected light (1) and specularly reflected light (2) components when photographing an ultraviolet image. That is, the user does not need to perform the process of removing the components of specularly reflected light (1) and specularly reflected light (2) using a polarizing plate as disclosed in Patent Document 1. Therefore, the user can easily use the evaluation service. Due to this premise, the ultraviolet image acquired by the acquisition unit 11 may include not only components of internally scattered light but also components of specularly reflected light (1) and specularly reflected light (2).

"Ultraviolet protection agents" are preparations containing ultraviolet absorbers (2-ethylhexyl para-methoxycinnamate, t-butylmethoxydibenzoylmethane, etc.) and/or ultraviolet scattering agents (fine titanium oxide, fine zinc oxide, etc.). Can be mentioned. Examples of the formulation include liquid, gel, semisolid, solid, foam, mist, and sheet forms. The present invention can be applied to all types of UV protection agents, but is particularly preferably applicable when a UV protection agent containing an ultraviolet absorber is placed on the surface of an object.

The "target object" is exemplified by a living body such as a human body, but is not limited to this, and may be any other object.

The "surface of the object" is exemplified by the outer surface of a living body such as skin, hair, nails, eyes, etc., but is not limited thereto, and may be the outer surface of other objects.

"Placement" refers to the state in which the coating film of the ultraviolet protective agent is placed in contact with the surface of the object. As the arrangement method, any means such as coating, pasting, adhesion, etc. can be adopted.

The acquisition unit 11 acquires the ultraviolet image transmitted by the user terminal 20.

Examples of the "user terminal 20" include, but are not limited to, a smartphone, a tablet terminal, a mobile phone, a mobile game, a personal computer, a smart watch, a smart mirror, a digital camera, and the like.

A "ultraviolet image" is an image taken and generated by an ultraviolet camera equipped with a sensor that detects ultraviolet light.

The user terminal 20 may be equipped with an ultraviolet camera function to take ultraviolet images. The function may be realized by connecting a predetermined device to the user terminal 20 or installing predetermined software, or may be provided in the user terminal 20 in advance from the shipping stage. After photographing an ultraviolet image using the user terminal 20, the user may transmit the ultraviolet image from the user terminal 20 to the evaluation device 10. Note that most indoor lighting generally does not contain ultraviolet rays, so when taking pictures indoors, a light source that contains ultraviolet rays is used. For example, an LED containing ultraviolet light can be attached to the user terminal 20 for use.

In addition, the user may take an ultraviolet image using an ultraviolet camera that is an external device that is logically and/or physically separated from the user terminal 20. Then, the user may input the ultraviolet image into the user terminal 20 by any means, and transmit the ultraviolet image from the user terminal 20 to the evaluation device 10. When shooting indoors, a light source that contains ultraviolet light is used. For example, it is also possible to use an ultraviolet camera by attaching an LED that emits ultraviolet light.

As shown in FIG. 1, the evaluation device 10 and the user terminal 20 are connected to a communication network 30 such as the Internet. Transmission and reception of ultraviolet images between the user terminal 20 and the evaluation device 10 is realized via the communication network 30. For example, an application program (software) dedicated to the evaluation service may be installed on the user terminal 20. Then, transmission (upload) of the ultraviolet image from the user terminal 20 to the evaluation device 10 may be realized via a function installed in the application program. In addition, a web page dedicated to the evaluation service may be prepared. After accessing the web page via the web browser installed on the user terminal 20, the ultraviolet image is transmitted (uploaded) from the user terminal 20 to the evaluation device 10 via the function installed in the web page. may be realized. Note that the transmission and reception of the ultraviolet image may be realized by other means, such as transmission and reception as an email attachment.

The image processing unit 12 uses a learning model to generate a processed image in which the specularly reflected light component is removed from the ultraviolet image. The specularly reflected light components to be removed are the specularly reflected light (1) and specularly reflected light (2) components described using FIG.

A learning model is prepared in advance that generates an ``image from which specularly reflected light components have been removed'' from an ``ultraviolet image taken of an object whose surface has a coating film of an ultraviolet protective agent.''

The means for generating a learning model is not particularly limited, and any means can be adopted. For example, the technique disclosed in Patent Document 2 may be used. An example of a learning model generating means will be described below.

The learning model uses ``an ultraviolet image taken of an object on which a coating film of an ultraviolet protection agent is placed on the surface, which includes a component of specularly reflected light,'' and an image that contains a component of specularly reflected light. It is generated by machine learning based on a plurality of training data paired with an "ultraviolet light image of the object that does not include a specularly reflected light component."

FIG. 5 shows an example of teacher data. The image (A) is an ultraviolet image taken of an object on which a coating film of an ultraviolet protective agent is disposed, and includes a specularly reflected light component. The image (B) is "an ultraviolet image taken of an object on which a coating film of an ultraviolet protective agent is disposed, and does not contain a specularly reflected light component." This image shows the condition when a commercially available O/W type UV inhibitor is applied to the face at a coating amount of 1.0mg/ ^cm2 , and a general xenon light source containing ultraviolet rays is used as the light source, and a camera is used. These images were taken with a general ultraviolet camera equipped with a bandpass filter in the ultraviolet range of 315 nm to 325 nm.

The means for generating the teacher data is not particularly limited, but it can usually be generated by using a light source, an ultraviolet camera, and a polarizing plate. For example, the technique disclosed in Patent Document 1 can be used. By appropriately adjusting the first polarizing plate and the second polarizing plate in the technique disclosed in Patent Document 1, the specularly reflected light component can be transmitted or removed. When adjusted to transmit the specularly reflected light component, an ultraviolet image that includes the specularly reflected light component is taken of an object whose surface is coated with an ultraviolet protective agent. I can do it. On the other hand, if the adjustment is made to remove the specularly reflected light component, "an ultraviolet image taken of an object with a coating film of an ultraviolet protective agent on its surface that does not contain the specularly reflected light component" Can be photographed.

Note that when using ``an ultraviolet image taken of an object with a coating film of an ultraviolet protection agent on its surface that does not include specularly reflected light components'' as training data, the generated ``ultraviolet protection It is also possible to adjust the brightness of an image that is an ultraviolet image taken of an object on which a coating film of the agent is disposed and that does not contain a specularly reflected light component.

As an example of the learning means, a case will be described in which a generator and a discriminator are used.

The generator uses the training data, ``an ultraviolet image taken of an object with a coating film of an ultraviolet protection agent on its surface, which includes a component of specularly reflected light'', to It is constructed using, for example, a multi-stage convolutional neural network (CCN) to generate an ultraviolet image taken of an object placed in the area, with the specularly reflected light component removed.

The discriminator uses the training data, ``an ultraviolet image taken of an object with a coating film of an ultraviolet protective agent on its surface, which does not include specularly reflected light components,'' and the ``ultraviolet ray image'' generated by the generator. An ultraviolet image taken of an object with a protective agent coating on its surface, from which the specularly reflected light component has been removed. The two images are configured to be identified as different when the degree of degree is not less than a predetermined ratio.

Then, the parameters of the classifier, that is, the predetermined value of the difference, are adjusted so that the two images can be discriminated, and the parameters of the generator are adjusted so that the classifier can generate an image that cannot be correctly identified. A generator provided with parameters resulting from the adjustment becomes a learning model used in the present invention.

A commercially available product A (Evita Moist Water Shield UV manufactured by Kao Corporation) containing an ultraviolet absorber as an ultraviolet protection agent was applied at 1 mg/cm ² to a 4 cm square part of the face. Under conditions that include the coated area and the uncoated area, it is determined that the image is an ultraviolet image taken of an object on which a coating film of an ultraviolet protective agent is placed, and that does not include specularly reflected light components. ``An ultraviolet image taken of an object with a coating film of ultraviolet protection agent placed on its surface, with the specularly reflected light component removed (image generated by the generator)'', and a total of three images are obtained. When the degree of concordance was confirmed using images, the degree of concordance was approximately 80.0%. An example of two images with a matching degree of about 80.0% is shown in FIG. The "image created using a polarizing plate to exclude specularly reflected light" is "an ultraviolet image taken of an object on which a coating film of an ultraviolet protective agent is placed, and which does not contain specularly reflected light components." ”. The "image from which specularly reflected light has been removed using machine learning" shown in the figure is "an ultraviolet image taken of an object with a coating film of an ultraviolet protective agent on its surface, and from which the specularly reflected light component has been removed" ( image generated by the generator). The degree of agreement was calculated using the following procedure.

(1) Areas with uneven coating (uncoated areas) from "an ultraviolet image taken of an object on which a coating film of an ultraviolet protective agent is placed and which does not contain specularly reflected light components" ) and use ImageJ to extract luminance value data in a range of 80 x 80 pixels.
(2) Create a graph in Excel with the horizontal axis as the brightness value and the vertical axis as the number of pixels, calculate the moving average value of 5 points in the vicinity, and define the point where the difference with the adjacent cell changes from negative to positive as the minimum value. .
(3) The integral value from luminance value 0 to the minimum luminance value is defined as the applied area (integral value 1), and the ratio of the integral value (integral value 2) of the entire histogram (integral value 1/integral value 2) seek.
(4) In the above (1) of "An ultraviolet image taken of an object on which a coating film of an ultraviolet protective agent is placed, the specularly reflected light component is removed (an image generated by a generator)" For the extracted range, similarly perform steps (2) to (4) to find the ratio. Note that the ranges arbitrarily extracted in (1) above are three for one image.
(5) The ratio calculated from "an ultraviolet image taken of an object with a coating film of ultraviolet protection agent on its surface, which does not include a specularly reflected light component" and The ratios calculated from "an ultraviolet image taken of an object placed on the surface, with the specularly reflected light component removed (image generated by the generator)" were compared, and the degree of agreement was calculated.

Similarly, when commercial product B (Sensai Silky Bronze Cellular Protective Cream for Body manufactured by Kao Corporation), which contains a UV absorber and a UV scattering agent, was used, the degree of concordance was approximately 70.0%.

The image processing unit 12 inputs the ultraviolet image acquired by the acquisition unit 11 into the learning model, and acquires a “processed image obtained by removing the specularly reflected light component from the ultraviolet image” output from the learning model.

The evaluation unit 13 evaluates the ultraviolet protective agent based on the processed image generated by the image processing unit 12, and generates evaluation result data indicating the results of the evaluation.

The evaluation unit 13 performs at least one of coating unevenness evaluation of the ultraviolet protection agent and performance evaluation of the ultraviolet protection agent as evaluation regarding the ultraviolet protection agent. The evaluation unit 13 may be configured to perform only one of the coating unevenness evaluation of the ultraviolet protective agent and the performance evaluation of the ultraviolet protective agent, or may be configured to perform both. Each will be explained below.

- Evaluation of uneven coating of UV protection agent -
In the uneven coating evaluation of this embodiment,
・Evaluation to identify painted areas and unpainted areas, and
・Evaluation that identifies areas where the amount of application is appropriate (not too much or too little) and areas where the amount of application is inappropriate (too much or too little).
It can be performed.

In a processed image in which the specularly reflected light component is removed from the ultraviolet image, the state of each location on the surface of the object shown in the processed image indicates the intensity of internally scattered light reflected at each location. The intensity of the internally scattered light reflected at each location depends on the amount of ultraviolet protection agent applied at each location. As the amount of UV protection agent applied increases, the intensity of reflected internally scattered light becomes weaker. Note that the intensity of the ultraviolet light (internally scattered light) reflected at each location, that is, the amount of the ultraviolet protective agent applied at each location, can be evaluated by the brightness value of the processed image. As shown in FIG. 11, when the applied amount of the ultraviolet protection agent is small, the intensity of internally scattered light becomes strong and the brightness value becomes large. On the other hand, when the applied amount of the ultraviolet protection agent is large, the intensity of internally scattered light becomes weak and the brightness value becomes small. An appropriate threshold value is set based on the brightness value of the processed image at the location where an appropriate amount of UV protection agent has been applied, and the application of UV protection agent at each location is determined by comparing the brightness value of each location in the processed image with this threshold value. It can be determined whether the amount is appropriate.

As shown in Figure 11, when the upper limit of the brightness value of the area where an appropriate amount of UV protection agent is applied is set as the first threshold value, the degree of intensity of the detected internally scattered light (brightness value) Locations larger than the first threshold are locations where no ultraviolet protective agent is applied at all, or where the UV protection agent is applied but the amount of application is inappropriate (too little). In addition, if the lower limit of the brightness value of the area where an appropriate amount of UV protection agent is applied is set as the second threshold value, the degree of intensity of the detected internally scattered light (brightness value) will be lower than the second threshold value. Small areas are areas where the ultraviolet protection agent is applied, but the amount applied is inappropriate (too much). A location where the intensity level (luminance value) of the detected internally scattered light is between the first threshold value and the second threshold value is a location where the ultraviolet protection agent is applied and the amount of application is appropriate.

The evaluation unit 13 evaluates areas where the intensity (luminance value) of the ultraviolet rays scattered within the object (internally scattered light) is greater than a first threshold, and determines where the applied amount of the ultraviolet protective agent is less than the first standard. It can be detected as a location. The evaluation unit 13 can then generate evaluation result data indicating the detection result.

The "first criterion" is a criterion for determining whether the amount of UV protection agent applied is acceptable (the portion where the amount of application is small). The first criterion is determined based on the first threshold value. The first threshold value is defined by the brightness value of the processed image. The first threshold value is the brightness value of the processed image at the location where the lower limit amount of the ultraviolet protection agent is applied in the appropriate amount range. As shown in FIG. 11, the first threshold is the upper limit of the rejection level at which the coating amount is determined to be inappropriate (too small). In other words, the first threshold is the lower limit of the acceptable level at which the amount of coating is determined to be appropriate. In the processed image, it is determined that the applied amount of the ultraviolet protective agent is inappropriate (small) at a location where the luminance value is larger than the first threshold value (luminance value). Areas where the amount of coating is too small will not provide sufficient UV protection.

The evaluation unit 13 can generate, as evaluation result data, an image in which the results of the uneven coating evaluation of the ultraviolet protective agent are superimposed on the image showing the object. Specifically, the evaluation unit 13 superimposes information indicating locations where the applied amount of the ultraviolet protective agent is less than the first standard (locations where the brightness value is greater than the first threshold value) on the image showing the target object. , it is possible to generate an image in which the location is prominently identified.

FIG. 6 schematically shows an example of an image generated by the evaluation unit 13. FIG. 6 shows an image generated by the evaluation unit 13 being displayed on the display D of the user terminal 20. In the illustrated example, the object is a human body. A frame M surrounding a partial area with a dotted line is superimposed on the image representing the object. The area surrounded by frame M is the area where the amount of UV protection agent applied is less than the first standard. In the illustrated example, advice is further displayed suggesting applying a little more UV protection agent to the area surrounded by frame M.

In the illustrated example, the predetermined location is clearly identified by surrounding it with a frame M, but other methods such as coloring the predetermined location or displaying an icon or stamp in the predetermined location may be used to make the predetermined location conspicuous for identification. Display may also be realized.

The "image showing the target object" may be an ultraviolet image acquired by the acquisition unit 11 or a processed image generated by the image processing unit 12. In addition to the ultraviolet image, the acquisition unit 11 may also acquire from the user terminal 20 an image of the object taken with a normal camera (a camera equipped with a sensor that detects light in the visible light range). Then, the image may be used as the above-mentioned "image showing the target object". Furthermore, an image displayed on the finder (display) of the user terminal 20 when the camera function is activated may be used as the above-mentioned "image showing the target object."

As another example, as shown in FIG. 11, the evaluation unit 13 evaluates the location where the intensity (luminance value) of the ultraviolet rays scattered in the object (internally scattered light) is smaller than the second threshold value. It can be detected as a location where the amount of protective agent applied is greater than the second standard. The evaluation unit 13 can then generate evaluation result data indicating the detection result.

The "second criterion" is another criterion for determining whether the amount of ultraviolet protection agent applied is acceptable (the portion where the amount of application is large). The second criterion is determined based on the second threshold value. The second threshold is defined by the brightness value of the processed image. The second threshold value is the brightness value of the processed image at the location where the upper limit of the appropriate amount range of UV protection agent is applied. As shown in FIG. 11, the second threshold is the lower limit of the rejection level at which it is determined that the coating amount is inappropriate (large). In other words, the second threshold is the upper limit of the pass level at which the coating amount is determined to be appropriate. In the processed image, it is determined that the applied amount of the ultraviolet protective agent is inappropriate (too large) at a location where the luminance value is smaller than the second threshold value (luminance value). Areas where too much is applied may cause a poor feeling of use. In addition, consuming excessive amounts may lead to purchasing more UV protection agents than necessary (wasteful use), and applying excessive amounts may cause the excess amount of UV protection agents to be washed away, increasing environmental impact. undesirable from this point of view.

The evaluation unit 13 can generate evaluation result data indicating the detection result using a method similar to the method shown in FIG. In the case of this example, the evaluation unit 13 superimposes information (frame M) indicating a location where the amount of UV protection agent applied is greater than the second standard on the image showing the target object, and identifies the location conspicuously. Displayed images can be generated. In this example, a notification that too much UV protection agent has been applied to the area surrounded by frame M is displayed, along with advice suggesting that a little more UV protection agent be applied to other areas. It's okay. In addition, the evaluation unit 13 uses a method similar to the method shown in FIG. It is also possible to generate and output an image that prominently identifies and displays both locations that exceed the standard (failure: too many). For example, the evaluation unit 13 evaluates the areas where the amount of UV protection agent applied is less than the first standard (fail: too little) and the area where the amount of UV protection agent applied is more than the second standard (fail: too much). ) may be generated and output on the same screen in an image in which each is displayed in a distinguishable manner.

The evaluation unit 13 determines that the degree of intensity (luminance value) of the detected ultraviolet rays (internally scattered light) is smaller than the first threshold value (the applied amount of the ultraviolet protective agent is larger than the first criterion), and A portion where the amount of UV protection agent applied is larger than the threshold value (the amount of UV protection agent applied is less than the second standard) is determined to be appropriate (passed: not too much, not too little).

-Performance evaluation-
The evaluation unit 13 can divide the detected ultraviolet rays by an arbitrary value and detect the result as ultraviolet reflectance. The lower the UV reflectance, the higher the UV protection effect. The evaluation unit 13 can generate evaluation result data indicating ultraviolet reflectance. Then, the UV protection effect of the UV protection agent can be evaluated based on the UV reflectance. Note that the arbitrary value may be the average ultraviolet reflection intensity of human bare skin or the like, or the ultraviolet reflection intensity of the object before applying the ultraviolet protection agent. For example, it can be calculated using one of the following formulas:
(UV reflectance) = (UV reflection intensity of skin coated with UV protection agent) / (average UV reflection intensity of bare skin without UV protection coating)
(UV reflectance) = (UV reflection intensity of the object coated with UV protection agent) / (UV reflection intensity of the object before applying the UV protection agent)

Returning to FIG. 4, the output unit 14 outputs the evaluation result data generated by the evaluation unit 13. The output unit 14 transmits evaluation result data to the user terminal 20. The user terminal 20 outputs the received evaluation result data via an output device such as a display, a projection device, or a printer.

Next, an example of the process flow of the evaluation device 10 will be described using the flowchart in FIG. 7.

First, the evaluation device 10 acquires an ultraviolet image of an object having a coating film of an ultraviolet protective agent on its surface (S10). The evaluation device 10 acquires the ultraviolet image transmitted by the user terminal 20.

Next, the evaluation device 10 uses the learning model to generate a processed image in which the specularly reflected light component is removed from the ultraviolet image (S11). Next, the evaluation device 10 performs evaluation regarding the ultraviolet protective agent based on the processed image, and generates evaluation result data indicating the evaluation results (S12).

Then, the evaluation device 10 outputs the evaluation result data generated in S12 (S13). The evaluation device 10 transmits evaluation result data to the user terminal 20. The user terminal 20 outputs the received evaluation result data via an output device such as a display, a projection device, or a printer (see FIG. 6).

<Second embodiment>
As explained in the first embodiment, the evaluation device 10 of this embodiment detects a location where the intensity (luminance value) of ultraviolet rays (internally scattered light) scattered within the object is greater than the first threshold value. , the area is detected as a location where the amount of applied ultraviolet protective agent is less than the first standard (a location where the amount of application is too small). In addition, the evaluation device 10 evaluates the areas where the intensity (luminance value) of the ultraviolet rays scattered in the object (internally scattered light) is smaller than the second threshold value, based on the amount of applied ultraviolet protective agent It is detected as a location where the amount of coating is too large (a location where the amount of coating is too large). Then, the evaluation device can dynamically change the first threshold value and the second threshold value. This will be explained in detail below.

Then, the evaluation unit 13 determines the first threshold based on at least one of the date and time at the time of evaluation, and the forecast of the amount of ultraviolet rays. That is, a first threshold value for determining whether the amount of application is "appropriate" or "insufficient (too small)" based on at least one of the date, time, and forecast of the amount of ultraviolet rays at the time of evaluation. Determine.

Further, as described in the first embodiment, the evaluation unit 13 evaluates the location where the intensity (luminance value) of the ultraviolet rays scattered in the object (internally scattered light) is smaller than the second threshold value. It can be detected as a location where the amount of the protective agent applied is greater than the second standard (a location where the amount of application is too large).

Then, the evaluation unit 13 determines the second threshold based on at least one of the date and time at the time of evaluation, and the forecast of the amount of ultraviolet rays. That is, a second threshold value for determining that the amount of application is too large is determined based on at least one of the date and time at the time of evaluation, and the forecast of the amount of ultraviolet rays.

The amount of ultraviolet light that falls on the ground can vary depending on the season. Therefore, the amount of UV protection agent that should be applied to the human body as a measure against UV rays may also vary depending on the season. By performing the uneven coating evaluation described in the first embodiment using criteria appropriate to the season at the time of evaluation, it is possible to provide the user with evaluation results appropriate to the season.

Correspondence information that associates the date with at least one of the first threshold value and the second threshold value is generated in advance and registered in the evaluation device 10. In the correspondence information, the first threshold value becomes smaller in a season when the amount of ultraviolet rays is higher, and the first threshold value becomes larger in a season when the amount of ultraviolet rays is lower. Furthermore, in the correspondence information, the second threshold value becomes smaller in seasons when the amount of ultraviolet rays is higher, and the second threshold value becomes larger in seasons when the amount of ultraviolet rays is lower.

After acquiring the date at the time of evaluation by any means, the evaluation unit 13 acquires at least one of the first threshold value and the second threshold value corresponding to the acquired date from the corresponding information, and the acquired first threshold value. The evaluation described in the first embodiment is performed using at least one of the threshold value and the second threshold value.

Additionally, the amount of ultraviolet light that falls on the ground can vary depending on the time of day. For this reason, the amount of UV protection agent that should be applied to the human body as a measure against UV rays may also vary depending on the time of day. By performing the uneven coating evaluation described in the first embodiment using appropriate criteria depending on the time of evaluation, it is possible to provide the user with an appropriate evaluation result.

Correspondence information that associates time with at least one of the first threshold value and the second threshold value is generated in advance and registered in the evaluation device 10. In the corresponding information, the first threshold value becomes smaller as the amount of ultraviolet rays increases, and the first threshold value becomes larger as the amount of ultraviolet rays decreases. Further, in the corresponding information, the second threshold value becomes smaller as the amount of ultraviolet rays increases at a time, and the second threshold value becomes larger as the amount of ultraviolet rays decreases.

After acquiring the time at the time of evaluation by any means, the evaluation unit 13 acquires at least one of the first threshold value and the second threshold value corresponding to the acquired time from the corresponding information, and the acquired first threshold value. The evaluation described in the first embodiment is performed using at least one of the threshold value and the second threshold value.

In addition, in recent years, forecasts for the amount of ultraviolet rays (sometimes called the ultraviolet index) have been published. By performing the uneven coating evaluation described in the first embodiment using appropriate criteria according to the content of this forecast, it becomes possible to provide the user with an appropriate evaluation result.

Correspondence information that associates the amount of ultraviolet rays shown in the forecast with at least one of the first threshold value and the second threshold value is generated in advance and registered in the evaluation device 10. In the correspondence information, the larger the predicted amount of ultraviolet rays is, the smaller the first threshold value is, and the smaller the predicted amount of ultraviolet rays is, the larger the first threshold value is. Further, in the corresponding information, the second threshold value becomes smaller as the predicted amount of ultraviolet rays increases, and the second threshold value becomes larger as the predicted amount of ultraviolet rays decreases.

After acquiring the contents of the forecast at the time of evaluation by any means, the evaluation unit 13 acquires at least one of the first threshold and the second threshold corresponding to the contents of the acquired forecast from the corresponding information, The evaluation described in the first embodiment is performed using at least one of the acquired first threshold value and second threshold value. The amount of ultraviolet rays indicated in the forecast may be the intensity of ultraviolet rays expressed in units such as "mW/cm ² ", or may be expressed as "strong, somewhat strong, normal, somewhat weak, weak", etc. It may be a value that expresses the intensity using any method.

As described above, the evaluation unit 13 can determine at least one of the first threshold value and the second threshold value, and evaluate the uneven coating of the ultraviolet protective agent based on the determined content. The other configuration of the evaluation device 10 of this embodiment is the same as that of the first embodiment.

As a result, it becomes possible to provide the user with evaluation results appropriate to the situation at that time.

<Third embodiment>
The evaluation device 10 of the present embodiment sets the first threshold value and the second threshold value regarding the degree (luminance value) of the "intensity of detected ultraviolet light (internally scattered light)" described in the first embodiment to the second threshold value. It can be dynamically changed using a method different from the second embodiment. This will be explained in detail below.

The evaluation unit 13 acquires information indicating the action schedule input by the user. The information indicates at least one of the length of time the user will be out and the time the user is out. The user operates the user terminal 20 to input the information. The information is then transmitted from the user terminal 20 to the evaluation device 10.

The means for accepting the user input may be realized using any technology. For example, it may be realized using an application program (software) dedicated to the evaluation service installed on the user terminal 20. In addition, an input form for accepting input of the information may be provided on the web page dedicated to the evaluation service.

Correspondence information that associates the length of time spent away with at least one of the first threshold value and the second threshold value is generated in advance and registered in the evaluation device 10. In the correspondence information, the longer the time spent outside the home, the smaller the first threshold value becomes, and the shorter the time the user goes out, the larger the first threshold value becomes. In addition, in the corresponding information, the longer the time spent outside the home, the smaller the second threshold value becomes, and the shorter the time spent outside the home, the larger the second threshold value becomes.

Note that if the time spent going out is long and the times at which the user goes out vary widely, the minimum value among the plurality of first threshold values corresponding to those times may be acquired. Furthermore, if the user is out for a long time and goes out at various times, the minimum value among the plurality of second threshold values corresponding to those times may be acquired.

The functions of the image processing section 12 and the evaluation section 13 are as described in the first to third embodiments. The output unit 14 outputs the evaluation result data via an output device such as a display, a projection device, or a printer (see FIG. 6). Note that most indoor lighting generally does not contain ultraviolet rays, so when taking pictures indoors, a light source that contains ultraviolet rays is used. For example, an LED containing ultraviolet light may be attached to the user terminal 20 (evaluation device 10) for use.

The other configurations of the evaluation device 10 of this embodiment are the same as those of the first to third embodiments.

Further, according to the evaluation device 10 of this embodiment, all processing can be completed within the evaluation device 10. Therefore, even in a situation where communication with an external device is not possible, the user can use the evaluation service.

<Fifth embodiment>
As shown in FIG. 10, in this embodiment, the evaluation apparatus of the present invention is configured as an evaluation system 100 and includes an acquisition section 11, an image processing section 12, an evaluation section 13, and an output section 14.

As an example, a plurality of user terminals 20 may each include an acquisition section 11 and an output section 14, and the server 1 may include an image processing section 12 and an evaluation section 13.

According to the evaluation system 100 of this embodiment, the same effects as the evaluation apparatus 10 of the first to fourth embodiments are realized.

<Modified example>
Modifications applicable to the first to fifth embodiments will be described below.

"Modification 1"
When taking an ultraviolet image using the ultraviolet camera function of the user terminal 20, as shown in FIG. The frame W may be displayed in a superimposed manner.

By taking a picture so that the face fits within this frame W, the distance between the camera and the face and the angle of view can be naturally adjusted to an appropriate state. As a result, it becomes possible to capture an ultraviolet image that allows evaluation by the evaluation unit 13 to be performed with high precision.

For example, a function to take an ultraviolet image may be provided within an application program (software) dedicated to the evaluation service installed on the user terminal 20. Then, when the application program dedicated to the evaluation service is started and the function to take an ultraviolet image is launched, the display of the user terminal 20 becomes a viewfinder, and the real-time photographed image is displayed on the finder. The frame W may be displayed superimposed on the image.

In addition, a function to take ultraviolet images may be provided within the web page dedicated to the evaluation service. Then, when accessing the web page dedicated to the evaluation service and launching the function to take ultraviolet images, the display of the user terminal 20 becomes a finder, and the real-time shot image is displayed on the finder. The frame W may be displayed superimposed on the image.

"Variation 2"
The user photographs the ultraviolet image so that the object and the standard patch are included in the ultraviolet image. For example, the standard patch may be photographed with the standard patch attached to the surface of the object, or the standard patch may be held in the hand or attached to a predetermined object and photographed. The standard patch has a known reflectance to ultraviolet light.

Then, the user applies the UV protective agent until the brightness of the UV image after applying the UV protective agent becomes darker than the standard patch. For example, if you prepare a standard patch that has the same reflectance as the recommended amount of UV protection agent applied, you can apply the UV protection agent until the brightness of the UV image becomes darker than the standard patch as described above. This allows the user to apply more UV protection agent than the recommended usage amount.

"Modification 3"
When photographing an ultraviolet image using the user terminal 20, a target color may be displayed as a guide on the image displayed on the finder (display).

Then, as in Modification 2, the user applies the ultraviolet protective agent until the color of the ultraviolet image after applying the ultraviolet protective agent becomes the same tone as the color guide. For example, if you prepare in advance a color guide that has the same color as the recommended amount of UV protection agent applied, apply the UV protection agent until the color of the UV image becomes the same tone as the standard patch as described above. By doing so, the user can apply more UV protection agent than the recommended usage amount.

"Modification 4"
When capturing an ultraviolet image using the user terminal 20, the proportion of saturated pixels among multiple images included in the ultraviolet image is set to a predetermined value (e.g. 50%, 40%, 30%, 20%, etc.). ) You may adjust it so that it is as follows. For example, when the brightness of an image is expressed in a range of 0 to 255 (0 is the darkest and 255 is the brightest), pixels with a brightness of 255 or more are saturated pixels. By doing this, the brightness of the ultraviolet image is adjusted, making it easier to see. The proportion occupied by the saturated pixels changes depending on whether a light source is included in the image, the distance between the camera and the subject, the angle of the camera, and the like. For example, saturated pixels are more likely to occur when a light source is present, when the camera is close to the subject, or when the camera angle is such that a lot of specularly reflected light is detected. The user himself/herself adjusts the photographing environment so that the proportion occupied by the saturated pixels is equal to or less than a predetermined value.

For example, the server 1 or the user terminal 20 may analyze the ultraviolet image and determine whether the proportion occupied by saturated pixels is below a predetermined value. If the user terminal 20 determines that the proportion occupied by saturated pixels is not less than the predetermined value, the user terminal 20 displays messages such as ``Please do not include the light source'', ``Move the camera away from the subject'', and ``Camera Advice such as "please change the angle of the screen" may be output to the user.

"Modification 5"
The output unit 14 may output product introduction information determined based on the evaluation results. For example, if the evaluation result is that "the product can be removed by rubbing," the output unit 14 can output product introduction information that introduces products that are difficult to remove by rubbing. The evaluation is performed, for example, by acquiring processed images before and after friction of an object coated with an ultraviolet protective agent, and based on the rate of change in brightness of the processed images before and after friction. If the rate of change is greater than or equal to a threshold value (preset numerical value), it can be evaluated that it will be removed by rubbing.

Correspondence information that associates each of the plurality of evaluation results that can be calculated by the evaluation unit 13 with the products recommended at the time of each evaluation result is stored in advance in the evaluation device 10 or the evaluation system 100. Based on the correspondence information, the output unit 14 specifies the products to be introduced in the case of each evaluation result.

"Variation 6"
The output unit 14 may output care information according to the season at the time of evaluation. Correspondence information that associates each of a plurality of seasons with care information indicating recommended skin care content for each season is stored in advance in the evaluation device 10 or the evaluation system 100. The output unit 14 specifies care information to be introduced at the time of evaluation based on the correspondence information.

"Modification 7"
The evaluation device 10 or the evaluation system 100 may obtain the forecast of the amount of ultraviolet rays by any means. Then, the output unit 14 may output information indicating the contents of the forecast.

"Modification 8"
The acquisition unit 11 may acquire an image of an object whose surface is not coated with an ultraviolet protective agent, taken with a normal camera (a camera equipped with a sensor that detects light in the visible light range). The evaluation unit 13 may use the image to visualize melanin in a conspicuous manner.

Melanin is photographed with a lower brightness value than bare skin. That is, the brightness value of the melanin area in the image is lower than the brightness value of the surrounding bare skin area. When photographing bare skin (objects that do not have a coating of UV protection agent placed on their surface), the area below a certain brightness value is defined as the melanin area, and the inside of the melanin area and the outer edge of the melanin area are defined as melanin areas. By coloring etc. on the image, it is possible to visualize it more conspicuously.

Melanin is a biological pigment that absorbs ultraviolet rays, so areas with a lot of melanin (for example, areas with spots on the face) have lower brightness values in the ultraviolet image than surrounding areas with less melanin. That is, the brightness value of a region with a lot of melanin in the ultraviolet image is lower than the brightness value of the surrounding bare skin region with a little melanin. The area of the photographed ultraviolet image with a brightness value below a certain value is set as an area with a lot of melanin, and that area and the outer edge of that area are colored on the ultraviolet image or visible light image to make it more visible. It is possible to do so.

“Modification 9”
The evaluation unit 13 can generate evaluation result data indicating the evaluation results regarding the ultraviolet protective agent based on the processed image. Specifically, the evaluation unit 13 can use the processed image itself as evaluation result data. In this modification, the output unit 14 outputs a processed image as evaluation result data.
