[0014] Hereinafter, the skin information collection and utilization system according to this embodiment will be described with reference to the drawings.

[0015] [1. The first skin information collection and utilization system] First, the first skin information collection and utilization system A1 will be described. Fig. 1 is an explanatory diagram showing the first skin information collection and utilization system A1 in use.

[0016] The first skin information collection and utilization system A1 according to this embodiment is a system for estimating the degree of exposure to ultraviolet rays from temporary changes in the skin caused by ultraviolet rays, and for providing information for keeping the skin beautiful based on this.

[0017] The first skin information collection and use system A1 is used, for example, at home, at a beauty salon, etc. Specifically, as shown in Fig. 1(a), a user U uses it on his / her own skin and puts into practice the obtained beauty information and advice, thereby enabling the user to maintain beautiful skin.

[0018] As shown in FIG. 1(b), in a beauty salon or the like, a counselor becomes a user U of the first skin information collection and use system A1, and by using it on the skin of a salon customer, the counselor can provide more appropriate counseling and treatment based on the beauty information and advice obtained from the first skin information collection and use system A1. In this specification, including the above description, a person who uses the skin information collection and use system is referred to as a "user," and a person who is the subject of obtaining the state of a specific skin element by the skin information collection and use system is referred to as a "subject." That is, in the embodiment shown in FIG. 1(a), the user U himself is also the subject T. In the embodiment shown in FIG. 1(b), the counselor is the user U, and the customer is the subject T.

[0019] 2 is an explanatory diagram showing the overall configuration of the first skin information collection and utilization system A1. The first skin information collection and utilization system A1 is composed of a skin information collection device 10, a smartphone 11, an internet network 12, and a server device 13.

[0020] The skin information collection device 10 is a device for acquiring the temperature state as a specified element from the skin of the monitored area of ​​the subject T, which in this embodiment is several points on the face, and supplying the acquired temperature state to the smartphone 11, and is a part that functions as an element state acquisition means in the first skin information collection and utilization system A1.

[0021] In this embodiment, the skin information collection device 10 has a substantially cylindrical outer shape, and a temperature sensor 10b that measures the temperature of the subject T's skin in a contact or non-contact manner is disposed at the tip of the skin information collection device 10.

[0022] The skin information collection device 10 receives power from the smartphone 11 via a communication cable 10a and transmits temperature state information obtained by the temperature sensor 10b to the smartphone 11. Note that communication between the skin information collection device 10 and the smartphone 11 may be performed wirelessly. In this case, the power used by the skin information collection device 10 may be configured to be supplied by a battery or the like.

[0023] The smartphone 11 is an information and communication terminal having a touch panel type liquid crystal display arranged over substantially the entire surface of one side, and is configured to be capable of executing programs such as various applications.

[0024] In addition, the smartphone 11 is provided with a camera unit 16 (front camera 16f, rear camera 16b) as an imaging means on the front side where the LCD display is located and on the rear side behind that, making it possible to obtain images of the subject T's face and macro images of the monitored area.

[0025] In the first skin information collection and utilization system A1, the smartphone 11, together with the server device 13, constitutes part of the skin information analysis device, and functions as a temporary change detection means as well as a notification means equipped with a notification section that can display information such as skin-related advice in the form of an image.

[0026] The smartphone 11 also has a built-in radio signal receiving unit of the Global Positioning System (GPS) as a geographical location information supply means. For example, if the subject T carries the smartphone 11 around with him / her, the smartphone 11 generates a behavior history that can be referenced as to when and where the subject T was, based on the location information and time information obtained from the radio signal receiving unit. In the following description, the combination of the skin information collecting device 10 and the smartphone 11 is also collectively referred to as the user device 15.

[0027] The smartphone 11 is also capable of sending and receiving information to and from the server device 13 via the Internet network 12. Therefore, for example, the smartphone 11 can supply to the server device 13 information on the position or element of a monitored area in which a temporary change has been detected by a temporary change detection means of the smartphone 11 (hereinafter also referred to as temporary change information), and can also receive from the server device 13 the results of analyzing this information.

[0028] In this embodiment, various means and functions, such as the function of the smartphone 11 as a temporary change detection means of the first skin information collection and utilization system A1, the function of the smartphone 11 as a geographical location information supply means, the function of communicating with the server device 13, and the function of supplying power and communicating with the skin information collection device 10, are configured to be performed by executing a dedicated program (dedicated app) installed on the smartphone 11.

[0029] The smartphone 11 also functions as an aging factor manifestation prediction means for predicting the manifestation of aging factors of the skin such as age spots, wrinkles, and irregular skin texture in each part of the face of the subject T based on information (described later) on the degree of exposure to ultraviolet rays estimated by the server device 13, and also functions as a notification information generating unit for generating an image including notification information on beauty based on the prediction of the manifestation of aging factors, that is, an image for displaying on the display of the smartphone 11 to notify the user U of the beauty information. These functions are also realized by the above-mentioned app.

[0030] The server device 13 is a computer device that functions as an exposure level estimation means in the first skin information collection and utilization system A1, and constitutes a part of the skin information analysis device together with the smartphone 11.

[0031] The server device 13 estimates the degree of exposure to ultraviolet rays at each part of the face based on the temporary change information supplied from the smartphone 11. Information regarding the estimated degree of exposure to ultraviolet rays is returned via the Internet network 12 to the smartphone 11 of the subject T, which is the source of the temporary change information.

[0032] In addition, the temporary change information supplied from the smartphone 11 to the server device 13 and the information on the degree of exposure to ultraviolet rays estimated in response thereto are stored in the database 13a. In particular, the server device 13 is configured to be accessible by a plurality of user devices 15, such as user devices 15a and 15b of different users, via the Internet network 12, and the individual data supplied to the server device 13 from each user device 15 is stored in the database 13a and can be used as big data. This big data may be provided for secondary use, as well as for use by the operator of the first skin information collection and use system A1. In other words, it can be provided for use by, for example, a cosmetics manufacturer or other party who wishes to use the big data, by entering into a license agreement.

[0033] Next, the procedure for using the first skin information collection and use system A1 having such a configuration and the flow of processing will be described while assuming a somewhat concrete scenario. Here, as shown in FIG. 1(a) above, it is assumed that the subject T is the user U, and that the user U carries the smartphone 11 on a daily basis. In addition, the user U has already started using the first skin information collection and use system A1 on a daily basis, and predetermined information about the user U has been accumulated in the memory area of ​​the smartphone 11 and the database 13a of the server device 13.

[0034] At the end of the day, before going to bed, user U starts using the first skin information collection and utilization system A1 to check today's (Sunday, May 16, 20XX) skin information. Subject T also performed the same operations as described below last night before going to bed. Therefore, the skin information check that subject T will perform from now on will check the information from the approximately 24 hours from last night's (previous) check to the present.

[0035] In using the first skin information collection and utilization system A1, the user U first starts up a program for providing skin information (hereinafter also referred to as a skin information providing application) that is pre-installed in the smartphone 11.

[0036] 3, a screen (user input screen 20) is displayed to prompt the user U to input information. In addition to today's date display section 21, the user input screen 20 is provided with a countermeasure input section 22 for inputting UV protection measures taken by the user U today, and a diary section 23 for freely inputting events of the day, and the user U makes input in each section.

[0037] In the example shown in FIG. 3, user U inputs into the countermeasure input section 22 that he / she did not take any special measures against ultraviolet rays today, and also inputs into the diary section 23 that he / she got up at 6:30 in the morning, did some housework, drove a car for a long time, and played tennis in the sunshine in the afternoon.

[0038] In addition, a digital mirror unit 24 is disposed on the user input screen 20. The digital mirror unit 24 is a portion that displays in real time the face of the user U photographed by the front camera 16f of the smartphone 11, and functions as a means for presenting a visible light image of the face to the user U (visible light image presenting means) in the same manner as a mirror.

[0039] The digital mirror unit 24 is used for confirmation when the user U measures the skin of each part of the face (obtains the state of a specific element) using the skin information collection device 10. That is, after inputting information into the above-mentioned measure input unit 22 and diary unit 23, the user U connects the skin information collection device 10 to the smartphone 11 via the communication cable 10a, and constructs the user device 15.

[0040] Then, as shown in FIG. 4, the face is adjusted so that it is within the angle of view G of the front camera 16f while referring to the digital mirror unit 24, and the tip of the skin information collection device 10 is placed against the skin on each part of the face to obtain the state of specific elements of the skin, in this case the state of the skin temperature, for each part.

[0041] In addition, in the first skin information collection and utilization system A1, the points at which temperature should be measured (areas to be monitored) are predefined as four locations: the forehead, the left and right cheeks, and the chin. The user U measures the temperature by placing the tip of the skin information collection device 10 against these points, but the user U can measure from any of these four locations in any order.

[0042] In other words, when the smartphone 11 matches the skin temperature condition acquired by the skin information collection device 10 at any of the four monitoring target areas on the face, which are predefined as the forehead, left and right cheeks, and chin, with the skin temperature condition acquired at any of these monitoring target areas, the smartphone 11 estimates the area from which the temperature condition was acquired from the four areas (forehead, left and right cheeks, and chin) based on the face image captured by the front camera 16f while the skin temperature condition is being acquired by the skin information collection device 10, for example by performing image analysis on the tip position of the skin information collection device 10, and is configured to treat the temperature condition acquired when the measurement button 10c of the skin information collection device 10 is pressed as the temperature condition at the area estimated at that time.

[0043] In this case, user U obtains the temperature status of each monitoring target body part in the following order: right cheek → chin → left cheek → forehead (not shown), and the temperature status for each monitoring target body part is stored in the memory area of ​​smartphone 11.

[0044] The smartphone 11 also refers to the past temperature conditions for each part of the body that have been stored in a memory area through the use of the first skin information collection and utilization system A1, detects temporary changes caused by ultraviolet rays in each monitored part of the body, and determines the extent of those changes.

[0045] The operation of this temporary change detection means can, for example, be to determine the skin temperature when it is considered that the user U is not affected by ultraviolet rays based on past movement history and previously observed amounts of ultraviolet rays as the normal skin temperature, and to determine that a temporary change has occurred if the temperature is higher than this, or to adopt known methods such as having an AI (artificial intelligence) determine complex factors to detect temporary changes.

[0046] Here, the temporary change detection means detects temporary changes in all four areas, namely the forehead, left and right cheeks, and chin, and the degree of the changes is evaluated on a four-level scale of "no change," "slight change," "somewhat clear change," and "noticeable change," with the forehead, left cheek, and chin being "somewhat clear change" and the right cheek being "noticeable change."

[0047] After performing the operation of detecting the temporary change, the smartphone 11 then transmits information (temporary change information) regarding the location and degree of the temporary change detected by the temporary change detection means to the server device 13 via the Internet network 12.

[0048] In addition, the smartphone 11 also transmits to the server device 13 the geographical location information of the user U at each time, i.e., a 24-hour movement history, which is generated by storing data generated by the GPS radio signal receiving unit, which is a geographical location information supply means, in a memory area.

[0049] On the other hand, the server device 13 is configured to execute a program that causes it to function as part of the first skin information collection and utilization system A1, and is configured to function as various means, such as analyzing information and transmitting the analysis results to each user device 15, which is a client.

[0050] The server device 13 receives the temporary change information and geographical location information supplied from the skin information collection device 10 via the Internet network 12, and estimates the degree of exposure based on the movement history based on the geographical location information, information on the amount of ultraviolet light observed in the area in the movement history separately obtained from the Internet, information on ultraviolet light countermeasures input by the user U in the countermeasures input section 22 of the user input screen 20, and various other information as necessary.

[0051] For example, based on the moving speed obtained from the geographical location information, it is determined that the user U moved by car, the temporary change information is corrected by taking into account the temperature, and further, by referring to the big data accumulated in the database 13a of the server device 13, the degree of exposure to ultraviolet rays of the user U is estimated for each part of the body, i.e., the forehead, the left and right cheeks, and the chin, by a known method, particularly an AI method, and further the overall degree of exposure is also estimated. The estimated degree of exposure may be a numerical value, but may also be evaluated in several stages. Here, the estimated information on the degree of exposure is output in five stages, i.e., low, slightly low, normal, slightly high, and high. The information on the degree of exposure estimated for each part and for the whole body is transmitted to the smartphone 11 of the user U via the Internet network 12.

[0052] The smartphone 11, which has received the estimated information on the degree of exposure, further acquires information on the amount of UV rays in the area based on the movement history from the GPS-based movement history stored in the memory area and information on the amount of UV rays in each area provided via the Internet network 12, and functions as an alarm information generation unit to generate a calendar image 30 that shows both the estimated degree of exposure and the actual amount of UV rays based on the behavioral history.

[0053] The generated calendar image 30 is displayed on the liquid crystal touch panel of the smartphone 11, which is the notification unit, as shown in Fig. 5. At this time, the actual amount of ultraviolet rays based on the behavioral history and the overall exposure level of the user U, which is estimated by the server device 13 functioning as the exposure level estimation means, are displayed as information in the square for Sunday, May 16th.

[0054] Here, when user U taps with his / her fingertip on the box for today (Sunday, May 16th) as indicated by the dotted line in Figure 5, smartphone 11 functions as an alarm information generating unit and generates a daily report image 40 based on today's weather information obtained from the Internet network 12, user U's movement history for today, UV protection information for user U entered on user input screen 20, and information on the estimated degree of exposure for each monitored area and for the entire body.

[0055] In addition, at this time, the smartphone 11 functions as an aging factor manifestation prediction means that refers to the history of the degree of exposure to ultraviolet rays that has been estimated each time the first skin information collection and utilization system A1 has been used, and based on this, predicts the manifestation of aging factors of the skin of the monitored area of ​​the user U, such as age spots, wrinkles, sagging skin, and other factors that make the face look old or that should be avoided from a cosmetic standpoint. In addition, the use of the first skin information collection and utilization system A1 up to this point improves the accuracy of prediction of the manifestation of aging factors thereafter.

[0056] The generated daily report image 40 is an image in which more detailed information is compiled in the form of a daily report, and is displayed on the liquid crystal touch panel of the smartphone 11, which is the notification unit, as shown in FIG.

[0057] The daily report image 40 includes today's weather information 41, behavioral information 42 of the user U, UV protection information 43, and overall estimated exposure degree information 44.

[0058] The weather information 41 is obtained via the Internet 12, and displays today's weather and UV radiation amount. Here, it is displayed that the weather today, May 16th (Sunday), is sunny, and the UV radiation amount is △△μw / cm 3 It is displayed that the amount of ultraviolet rays was very high. As shown in FIG. 6, the amount of ultraviolet rays may be expressed as a specific value, but it may also be expressed simply as a number classified into multiple levels, such as high or low.

[0059] The behavior information 42 indicates the movement history of the user U today, and here the information is presented by displaying the trajectory on a map.

[0060] The ultraviolet ray protection information 43 is information displayed based on the information input by the user U on the user input screen 20, and here, it is displayed that the user U did not take any particular measures against ultraviolet ray today.

[0061] The estimated exposure level information 44 is information that is estimated regarding the user U's exposure level to ultraviolet rays today, and is displayed here under the heading of "effects of ultraviolet rays" so that it is easy for the user U to understand. Here, it is displayed that the overall exposure level of the user U to ultraviolet rays is estimated to be "high."

[0062] The estimated exposure level information 44 also includes a details confirmation button 44a for displaying details of the effects of ultraviolet rays, that is, the estimated exposure level for each monitored area at each predetermined time in chronological order.

[0063] When the user U presses this detail confirmation button 44a, the notification information generation unit, which constitutes the notification means of the smartphone 11, supplies image data for displaying the estimated exposure degree for each specified time period for each monitored area in chronological order to the liquid crystal touch panel, which is the notification unit, and displays it.

[0064] Fig. 7 is an explanatory diagram showing a body part exposure degree information display screen 50 displayed by pressing the details confirmation button 44a by the user U. As shown in Fig. 7, body part exposure degree information display screen 50 displays body part information 51 (51a to 51d) for each of the four monitoring target body parts, namely, the forehead, right cheek, left cheek, and chin.

[0065] Moreover, a part display section 52a showing the parts to be monitored and a time series display section 52b are arranged in the part-by-part information 51. The part display section 52a is a section that displays the degree of exposure of which part of the body is shown by the time series graph shown in the time series display section 52b.

[0066] The time series display section 52b is a section that shows a time series graph of the degree of exposure in the parts of the body shown in the part display section 52a, where the horizontal axis represents time and the vertical axis represents the degree of exposure evaluated on a five-level scale of “low,” “slightly low,” “normal,” “slightly high,” and “high,” and shows the change in the degree of ultraviolet light exposure in a specified monitored part of the user U approximately every hour.

[0067] Here, looking at the four time series display sections 52b, it can be seen that the exposure level trends common to each part are low to somewhat low from the morning until 9:00, but after 9:00 when the drive started, exposure to UV rays continued throughout the morning. Also, although the impact of UV rays was low indoors at lunchtime, the person played tennis in the sun for about two hours in the afternoon, which suggests that the person was exposed to a large amount of UV rays. After that, it can be seen that the exposure level gradually decreased as the sun went down while the person was on the way home.

[0068] Also, what should be noted here is that, as shown by the dashed line in the time series display section 52b for the right cheek, the degree of exposure to ultraviolet rays during the drive from 9:00 to 12:00 is higher than that of other parts. As will be mentioned later, this is because the server device 13, which functions as an exposure degree estimation means, estimates that the right cheek was exposed to strong sunlight from the driver's seat side by taking into account the movement history of the user U, etc.

[0069] A time axis change button 54 is also arranged on the information display screen 50. This time axis change button 54 is a button for changing the time axis of the time series graph displayed in the time series display section 52b, i.e., the horizontal axis, and is equipped with a plus button 54a which zooms in the range displayed on the horizontal axis from 1 month → 1 week → 1 day each time the button is pressed, and a minus button 54b which zooms out the range from 1 day → 1 week → 1 month.

[0070] For example, as shown in FIG. 7, when the time series graph displayed in the time series display section 52b shows the fluctuations in the degree of exposure for each time of day, pressing the minus button 54b causes the time axis to zoom out and show the fluctuations in the degree of exposure for each day of the week.

[0071] Moreover, when the minus button 54b is pressed again in this state, the time axis is further zoomed out and a display is displayed showing the fluctuation of the degree of exposure for each day in a month.

[0072] Conversely, when the plus button 54a is pressed while the display shows the fluctuation in the degree of exposure for each day in a month, the time axis is zoomed in and the display returns to show the fluctuation in the degree of exposure for each day in a week. When the plus button 54a is pressed again, the time series graph shown in the time series display section 52b returns to show the fluctuation in the degree of exposure for each time of day.

[0073] Further, a back button 53 is arranged on the information display screen 50, and the user U can return to the daily report image 40 by pressing the back button 53.

[0074] Returning to the explanation of the daily report image 40, as shown in Fig. 6, a part diagram display section 45 in which information on each part is written together with a face image is arranged in the lower half of the daily report image 40. The part diagram display section 45 is composed of a face image 46 and a part explanation 47.

[0075] The facial image 46 is an image that allows intuitive recognition of each part of the face that is to be monitored, and here, a real-life facial image of the user U taken by the front camera 16f when acquiring the temperature state of each part that is to be monitored shown in Fig. 4 is used. Note that this facial image 46 does not necessarily have to be a real-life image, and may be an illustration that includes the parts that are to be monitored.

[0076] The explanation of each part 47 is a part that displays at least one of the following information: information about temporary condition changes in each monitored part, information about the estimated degree of exposure in that part, and information about skin aging factors predicted to be expressed in that part. Here, an example is shown in which all three of these pieces of information are displayed.

[0077] Further, the part description 47 is displayed for each of the monitored parts, such as part description 47a for the forehead, part description 47b for the right cheek, part description 47c for the left cheek, and part description 47d for the chin.

[0078] For example, referring to the explanation of each part 47c regarding the left cheek, the degree of temporary change is a fairly clear change, the estimated degree of exposure is estimated to be somewhat high, and furthermore, as described above, the smartphone 11 functions as a means for predicting the onset of aging factors, and thus the onset of spots is predicted.

[0079] Similarly, for the forehead and chin, the degree of temporary changes was somewhat clear and the estimated degree of exposure was estimated to be somewhat high, with the appearance of wrinkles on the forehead and sagging on the chin predicted.

[0080] In other words, an analysis based on various information such as today's behavioral history, actual amount of UV rays, and skin temperature state (element state) acquired by skin information collection device 10 indicates that the forehead, left cheek, and chin were exposed to a level of UV rays that was judged to be "slightly high."

[0081] In contrast, referring to the explanation for each part 47b regarding the right cheek, although it is similar to the other three in that the appearance of aging factors (spots) is predicted, the degree of temporary change is significant and the estimated degree of exposure is estimated to be high, suggesting that the impact of ultraviolet rays was greater than in other parts of the body.

[0082] This reflects the fact that, when the server device 13 estimates the degree of exposure using AI technology, it refers to the user U's behavioral history, and takes into consideration the fact that the user U traveled by car based on the speed of travel, the direction of travel, the solar radiation conditions, and even the fact that the temporary change in the right cheek was noticeable, and estimates that the user U was seated in the driver's seat and drove while being exposed to solar radiation for a long period of time. Conversely, even if the cheek temperature is higher than normal and is detected as a temporary change, if the temperatures of both the left and right cheeks are approximately the same, it is possible to take other circumstances into consideration and estimate that the user has a fever due to a cold or the like, and to perform an appropriate operation without reflecting this in the estimated degree of exposure.

[0083] In this way, the first skin information collection and utilization system A1 infers from temporary changes in the skin of the subject T (user U) that the subject T has been exposed to a lot of UV rays and provides advice. By obtaining information about each monitored area, the user U can clearly, or in other words, know quantitatively to a certain extent what kind of care should be given to each area, thereby enabling him or her to keep his or her skin beautiful.

[0084] A future face prediction button 48 is also displayed on each part diagram display section 45. This future face prediction button 48 is a button for displaying the future predicted appearance of the user U, and when the future face prediction button 48 is pressed, the smartphone 11 generates a future face image by adding an aging element to an actual face image of the user U taken by the front camera 16f when acquiring the temperature state of each monitoring target part shown in Fig. 4, and displays the generated image on the liquid crystal touch panel.

[0085] 8 is an explanatory diagram showing the future face display screen 60. The future face image 61 displayed approximately in the center of the future face display screen 60 is a face image in which graphics of aging factors predicted by the above-mentioned aging factor manifestation prediction means are displayed in the predicted areas, and here a realistic future face image 61 obtained by processing a real-life facial image of the user U is displayed.

[0086] Specifically, an image of wrinkles is displayed on the forehead where wrinkles are predicted to appear, images of blemishes are displayed on the left and right cheeks where blemishes are predicted to appear, and an image of sagging skin is displayed on the chin where sagging skin is predicted to appear.

[0087] Furthermore, the right cheek, which is estimated to have been exposed to ultraviolet rays, is reproduced in the future face image 61 with more age spots than the left cheek.

[0088] By displaying the future face display screen 60 in this manner, it is possible to more reliably raise the awareness of the user U regarding the importance of measures against ultraviolet rays.

[0089] Incidentally, with regard to the above-described first skin information collection and utilization system A1, the configuration of each part can be appropriately changed without departing from the spirit of the present invention.

[0090] For example, in the above-mentioned first skin information collection and utilization system A1, an example was shown in which a smartphone 11 was used to construct the user device 15, but this is not limited to this and may be, for example, a tablet, a laptop, a desktop computer, etc., or it may be a dedicated device for constructing the first skin information collection and utilization system A1.

[0091] In addition, in the example of the first skin information collection and utilization system A1 described above, the user U is also the subject T as shown in FIG. 1(a), but it goes without saying that the user U and the subject T may be separate, such as in a beauty salon, as shown in FIG. 1(b).

[0092] In addition, in the first skin information collection and utilization system A1, the facial image 46 shown in the daily report image 40 and the future facial image 61 shown on the future facial display screen 60 are based on real-life images of the subject T, but are not limited to this and may be based on illustrated images.

[0093] Furthermore, in the daily report image 40, the behavior information 42 is displayed as a map, but it is also possible to configure the behavior information to be displayed as text information.

[0094] In addition, in the first skin information collection and utilization system A1, when detecting a temporary change, the skin temperature of the monitored part when the user U is considered not to be affected by ultraviolet rays is taken as the normal skin temperature, and if the temperature is higher than this, it is determined that a temporary change has occurred, but this is not limited to this example, and it is also possible to refer to the skin temperature of a body surface part other than the monitored part at approximately the same time as acquiring the state of the skin temperature of the monitored part, and to determine that a temporary change has occurred if this temperature difference is equal to or greater than a predetermined value. In this case, the measurement of the skin temperature of the body surface part other than the monitored part may be provided with a different temperature sensor as the second element state acquisition means, different from the temperature sensor used to measure the temperature of the monitored part.

[0095] In addition, in the first skin information collection and utilization system A1, the detection target for temporary changes in skin is skin temperature, but this is not limited thereto, and for example, a sensor that identifies skin color may be provided to capture temporary changes in skin color, or both skin temperature and skin color may be measured. If temporary changes are detected by referring to both, the degree of exposure to ultraviolet rays can be estimated more accurately than when temporary changes are detected by only one of them.

[0096] In addition, when detecting temporary changes in skin color, a sensor for identifying skin color can be configured to capture skin image data using an image sensor, and the data can be processed by a control unit to compare the skin color with past skin color to identify it.

[0097] In this case, the imaging element may be an imaging element of the camera unit 16 provided in the smartphone 11. For example, a temporary change in skin color may be captured based on an image of substantially the entire face captured when displayed on the digital mirror unit 24 of the user input screen 20.

[0098] If the camera unit 16 has a macro function, it is also possible to bring the camera unit 16 close to the skin of the monitored area to capture a close-up shot and capture a temporary change in skin color. Even if the smartphone 11 does not have a macro function, a close-up lens unit 70 as shown in Fig. 9(b) can be separately attached to the rear camera 16b of the smartphone 11 shown in Fig. 9(a).

[0099] With this configuration, as shown in FIG. 10, the user can obtain a skin image by bringing lens portion 71 of close-up lens unit 70 close to the skin of the area to be monitored and taking an image.

[0100] Furthermore, in the first skin information collection and utilization system A1, the skin information collection device 10 is not equipped with a means for capturing images, but it goes without saying that the skin information collection device may be equipped with an imaging means.

[0101] For example, as shown in Fig. 11, a macro lens camera unit 80d as an imaging means capable of taking close-up images of the skin can be provided at the tip of the skin information collecting device 80, and the temperature state and the captured image of the monitored area can be obtained together with a temperature sensor 80b also provided at the tip. In this case, another temperature sensor 80e, which is the second element state obtaining means described above, can be provided at the gripping part of the skin information collecting device 80. By detecting a temporary state change related to a specific element of the skin based on the temperature information from the temperature sensor 80b and the temperature sensor 80e and the captured image from the macro lens camera unit 80d, the degree of exposure to ultraviolet rays can be estimated with higher accuracy. In addition, the accuracy of analysis can be improved by predicting the amount of exposure to ultraviolet rays based on the close-up skin image and the skin temperature.

[0102] The acquired skin image can be used to detect skin texture and blemishes, and in beauty salons, for example, the color tone and contrast can be adjusted to make the image easier to see skin texture and blemishes, and this can be presented to customers to give advice, etc.

[0103] Specifically, a skin analysis screen 90 as shown in Fig. 12 may be displayed. In addition to a skin analysis image display section 91 and a skin analysis evaluation display section 92, the skin analysis screen 90 includes today's weather information 41, similar to the daily report image 40 described above, UV protection information 43, overall estimated exposure degree information 44, and a section 45 illustrating each part.

[0104] The skin analysis image display section 91 is a section that displays close-up images of the skin captured by the above-mentioned rear camera 16b or macro lens camera section 80d, and images processed based on the close-up images, and in addition to the normal skin image 91a, it displays images in which the texture and blemishes are accentuated by image adjustment such as contrast. Such image display allows the subject T to more clearly recognize the condition of his / her skin.

[0105] The skin analysis evaluation display section 92 is a section that displays the analysis results of the skin condition obtained by analyzing the acquired close-up captured image of the skin, and here, the analysis results are displayed in a radar chart for each item such as texture, transparency, whitening level, age spots, pore condition, amount of fine wrinkles, etc. In addition, below the radar chart, a comparison result with the general skin of the same age is shown, allowing the user to understand the condition of their skin relative to their age.

[0106] These analysis results may simply be displayed on the skin analysis evaluation display unit 92, but may also be referred to when the exposure level estimation means estimates the degree of exposure to ultraviolet rays. With this configuration, the accuracy of estimating the degree of exposure can be further improved.

[0107] Also, the display may be configured to present analysis results such as those shown in the skin analysis image display section 91 and the skin analysis evaluation display section 92, as well as other skin information, and introduce recommended products according to the skin condition. For example, on each screen for providing information, specifically the calendar image 30, the daily report image 40, the information display screen 50, the future face display screen 60, the skin analysis screen 90, etc., it is possible to display and introduce images of cosmetics such as lotions that cool skin that has become hot due to ultraviolet rays, or images of skin care devices with facial beautifying effects. In particular, it is possible to suggest cosmetics that are suitable for the amount of ultraviolet rays exposed and the part of the body, or to suggest a schedule for using cosmetics based on time-series data.

[0108] In the first skin information collection and utilization system A1, a feedback information input button 93 is arranged in each part explanation 47 of each part diagram display section 45.

[0109] This feedback information input button 93 functions as a means for the user U to input the validity of the estimated ultraviolet ray exposure result, and is composed of three buttons: an upward revision button 93a, a validity button 93b, and a downward revision button 93c.

[0110] Here, referring to the explanation of each part 47a relating to the forehead, if the user U checks the explanation of each part 47a relating to the forehead and gets the impression that "in reality, I may have been exposed to more UV rays," then by pressing the upward correction button 93a, the user U's feeling is referred to in the estimation of the degree of UV exposure in the server device 13, and is fed back to improve the reliability of the prediction.

[0111] In addition, if the user U gets the impression that "maybe he / she has not actually been exposed to that much UV rays," he / she presses the downward revision button 93c, and if he / she gets the impression that "the estimated result is approximately reasonable," he / she presses the reasonableness button 93b.Similarly, the user U's intuition is referenced in the estimation of the degree of UV exposure in the server device 13, and is fed back to improve the reliability of the prediction.

[0112] In addition, in the first skin information collection and utilization system A1, the areas of the skin to be monitored are four: the forehead, the left and right cheeks, and the chin. However, this is not limited to these areas, and other areas such as the space between the eyebrows, the face line, the nose, under the nose, and under the chin may also be monitored, and areas other than the face may also be monitored.

[0113] [2. The second skin information collection and utilization system] Next, the second skin information collection and utilization system A2 will be described. Fig. 13 is an explanatory diagram showing the second skin information collection and utilization system A2 having the form of a facial treatment device 100.

[0114] The second skin information collection and utilization system A2 is generally similar to the first skin information collection and utilization system A1 described above in that it acquires the state of specified elements in the skin of each part of the face, which is the monitored area, detects temporary changes, and estimates the degree of exposure to ultraviolet rays based on this. However, it is functionally different in that it provides treatment based on the obtained estimated degree of exposure.

[0115] In addition, the above-mentioned first skin information collection and utilization system A1 was constructed by connecting a skin information collection device 10, a smartphone 11, an internet network 12, a server device 13, etc., whereas the present second skin information collection and utilization system A2 does not link with other devices, but is configured significantly differently in that the system is completed within the facial beauty treatment device 100 shown in Figure 13.

[0116] This device is the second skin information collection and utilization system A2, but is also the facial beauty treatment device 100. For ease of explanation, the configuration will first be explained from the perspective of the facial beauty treatment device 100, and then the configuration and operation, etc. will be explained from the perspective of the second skin information collection and utilization system A2.

[0117] As shown in FIG. 14, the facial treatment device 100 is configured so that the user U holds the treatment device main body 112 and places the contact portion 114 against the skin, whereby the contact portion 114 functions as an ion introduction portion to treat the skin.

[0118] The intensity of this treatment is controlled by the second skin information collection and utilization system A2 based on the degree of exposure to ultraviolet rays. That is, the treatment intensity is increased for areas estimated to be highly exposed to ultraviolet rays, realizing efficient treatment, while the treatment intensity is decreased for areas estimated to be less exposed, reducing power consumption.

[0119] As shown in FIG. 13, the facial beauty treatment device 100 has an external shape that is roughly a long rectangle when viewed from the front and is like a thick plate that curves slightly backward from the middle to the top. The treatment device main body 112 has a circumference that can be held in the palm of the hand, while its vertical length is such that the top extends beyond the hand when the housing is held.

[0120] The treatment device main body 112 is a main part of the facial treatment device 100 in which the second skin information collection and utilization system A2 and the iontophoresis unit are mounted, and has a substantially cylindrical contact part 114 protruding from the upper front surface thereof.

[0121] The contact portion 114 is a portion that comes into contact with the skin to be treated, and is made of a conductor such as metal so as to function as one electrode for forming a potential gradient when the iontophoresis portion is functioning.

[0122] Specifically, cotton 115 soaked in cosmetics or the like is placed on the upper surface 114a of the contact portion 114, and a ring-shaped fixture (not shown) is attached from above the cotton 115, so that the cotton 115 can be fixed on the contact portion 114. In this state, by operating the iontophoresis unit described later and passing electricity through the cotton 115 to the skin against which the contact portion 114 is in contact, it is possible to perform iontophoresis of a predetermined component contained in the cosmetics or the like. At this time, heating is also performed by a heater as necessary. Although not shown, the electrode that becomes the other side during iontophoresis is disposed on the rear part of the treatment device main body 112.

[0123] Furthermore, on an upper surface 114a of the contact portion 114, a skin color acquisition portion 102 and a temperature acquisition portion 103 are provided.

[0124] The skin color acquisition unit 102 is a component for acquiring the color state of a specific element of the skin using an image sensor (not shown) built into the contact unit 114. In a skin information collection mode described below, information relating to the skin color state (hereinafter also referred to as skin color information) acquired by the skin color acquisition unit 102 is supplied to the control unit 130 and used to detect temporary changes in the skin state.

[0125] The temperature acquisition unit 103 is also a part for acquiring the temperature state as a predetermined element of the skin. Information on the skin temperature state acquired by the temperature acquisition unit 103 in the skin information collection mode (hereinafter also referred to as skin temperature information) is supplied to the control unit 130 and used to detect temporary changes in the skin state. A heat insulating part 103a made of a material with low thermal conductivity is formed around the temperature acquisition unit 103. This heat insulating part 103a is intended to prevent the heat from affecting the measurement by the temperature acquisition unit 103 when the contact part 114 is heated to warm the skin.

[0126] An operation unit 117 is provided on the front surface of the facial beauty treatment device 100, and enables the user U to input instructions to a control unit 130 housed inside the treatment device main body 112.

[0127] In addition, a palm temperature acquisition unit 101 is provided on the side of the facial treatment device 100. This palm temperature acquisition unit 101 is a second temperature acquisition unit for measuring the temperature of the palm as the skin of another body surface part, not the skin of the face which is the target of acquisition of the state of a specific element, that is, a part corresponding to the second element state acquisition means. Note that the other side electrode for the above-mentioned ion introduction, which is the opposite electrode of the contact part 114 and provided on the back part of the treatment device main body 112, can be provided at the same position as this palm temperature acquisition unit 101, not on the back part. That is, it is preferable that the contact surface of the palm temperature acquisition unit 101 is formed of a metal with good thermal conductivity, but since metal has conductivity, it can also function as the other side electrode for ion introduction, which can contribute to reducing the number of parts.

[0128] The operation unit 117 is provided with a power button 117a, a function button 117b, and a mode selection button 117c, and each button is electrically connected to the control unit .

[0129] The power button 117a is a button for starting up or powering down the facial beauty treatment device 100. When the power button 117a is pressed before the start-up, power is supplied from a power source (a battery, not shown, built into the facial beauty treatment device 100 in this embodiment) to the control unit 130, and the second skin information collection and use system A2 and the iontophoresis unit can be operated. When the power button 117a is pressed after the start-up, the power to the control unit 130 is cut off and the facial beauty treatment device 100 returns to the state before the start-up.

[0130] The function button 117b is a button that performs different functions depending on the mode selected by the mode selection button 117c described below. When the operation unit 117 is pressed in the skin information collection mode, the elemental condition of the skin is acquired, similarly to the measurement button 10c of the skin information collecting device 10 in the first skin information collection and utilization system A1 described above. In this facial treatment device 100 (second skin information collection and utilization system A2), both the skin temperature and the skin color are acquired as the elemental condition of the skin.

[0131] Moreover, when the operation unit 117 is pressed in the treatment mode, power is supplied to a pulse current supply circuit 49 (described later) constituting the iontophoresis unit, and ions are introduced into the skin contacted with the contact unit 114 via the cotton 115. In addition, power is supplied to a heater, a sensor, and the like constituting the heating unit, and the skin contacted with the contact unit 114 is heated as necessary.

[0132] As described above, the mode selection button 117c is a button for switching between the skin information collection mode and the treatment mode. Although it is possible to use the facial treatment device 100 only in the treatment mode, in order to realize efficient treatment, the general usage mode assumed for this device is to first execute the skin information collection mode to estimate the degree of exposure to ultraviolet rays for each part of the skin, and then perform treatment based on the estimation result.

[0133] An indicator lamp 117d is provided at the upper position of the operation unit 117. The indicator lamp 117d is turned off before the facial treatment device 100 is started and turned on after the facial treatment device 100 is started under the control of the control unit 130, thereby indicating the start-up state of the facial treatment device 100. The indicator lamp 117d is made of a so-called multi-color light-emitting LED, and notifies the user U of whether the facial treatment device 100 is in the skin information collection mode or the treatment mode by changing the color.

[0134] Next, regarding the facial beauty treatment device 100, the viewpoint is shifted to the second skin information collection and utilization system A2 according to this embodiment, and the procedure of use and the flow of processing are explained while assuming a somewhat concrete scene. The second skin information collection and utilization system A2 will also be explained assuming a case where the subject T is the user U. The user U has already started using the second skin information collection and utilization system A2 on a daily basis, and the skin color information (normal skin color information) measured by the user U for each monitoring target part when not affected by ultraviolet rays has already been stored in the memory area provided inside the facial beauty treatment device 100. Note that the monitoring target parts are set to four parts on the face, namely the forehead, the left and right cheeks, and the chin, as in the first skin information collection and utilization system A1 described above.

[0135] When using the second skin information collection and utilization system A2, the user U first presses the power button 117a to start up the second skin information collection and utilization system A2 (facial beauty treatment device 100).

[0136] Next, when the mode selection button 117c is operated to select the skin information collection mode and the function button 117b is pressed, the second skin information collection and utilization system A2 transitions to the skin information collection mode.

[0137] Here, the control unit 130 guides the user U by emitting voice so as to measure the skin of each part of the face (operation to acquire the state of a predetermined element). Specifically, the control unit 130 functions as a guidance means that sequentially guides the user U to the parts where the state of the skin color and the state of the skin temperature should be acquired by the skin color acquisition unit 102 and the temperature acquisition unit 103, which are element state acquisition means, namely, the four parts of the face, namely the forehead, the left and right cheeks, and the chin.

[0138] For example, when the control unit 130 functions as a guide means and issues a guide from the built-in speaker saying, "Place the contact part against your right cheek," the user U is prompted to acquire the state of a specific element of the right cheek, as shown in Fig. 14, and by pressing the function button 117b, information on the skin color state of the right cheek is acquired by the skin color acquisition unit 102, and information on the temperature state of the right cheek is acquired by the temperature acquisition unit 103. At this time, information on the temperature state of the palm is also acquired by the palm temperature acquisition unit 101, and each is supplied to the control unit 130.

[0139] Next, the built-in speaker gives instructions such as "Place the contact part against your left cheek," "Place the contact part against your chin," and "Place the contact part against your forehead," and each time the instruction is given, the user U places the contact part 114 at the specified location and presses the function button 117b to obtain information on the skin color condition and temperature condition at each part. Each piece of information obtained is stored in a specified memory area of ​​the second skin information collection and utilization system A2.

[0140] In this way, the second skin information collection and utilization system A2 is characterized in that, in acquiring the status of a specific element, when matching a plurality of monitored areas with the status of a specific skin element acquired by the element status acquisition means at each monitored area, the status of the specific element acquired immediately after each guidance by the guidance means is regarded as the status of the specific element of the same guided area.

[0141] Next, the control unit 130 refers to the normal skin color information stored in advance in a specified memory area and the palm temperature state acquired by the palm temperature acquisition unit 101, detects temporary changes caused by ultraviolet rays in each monitored area, and determines the extent of the changes.

[0142] Specifically, the skin color information acquired from each part is compared with the normal skin color information, and if the redness level is higher than a predetermined level, it can be determined that there is a temporary change. Also, the temperature information acquired from each part is compared with the palm temperature state information, and if the temperature is higher than a predetermined level, it can be determined that there is a temporary change. In addition, when comparing the skin color information acquired from each part with the normal skin color information, it is desirable to generate preliminary information, such as whether the subject T is dark-skinned or light-skinned, based on the normal skin color information. If the subject T has dark skin, there is a tendency that changes in skin color caused by ultraviolet rays are less likely to appear. Even in such a case, by generating preliminary information in advance and referring to this, it is possible to take into account that even a slight change may be caused by exposure to ultraviolet rays, and it is possible to estimate the degree of temporary change with higher accuracy.

[0143] In addition, the degree of the temporary change can be estimated by comprehensively taking into account the results of the temporary change obtained based on the skin color information and the results of the temporary change obtained based on the temperature information. By carrying out such processing, the accuracy of estimating the degree of the temporary change can be further improved.

[0144] Here, the temporary change detection means takes into account both the skin color information and the temperature information, and as a result, the degree of temporary change is determined to be "no change" for the forehead and "chin" on the four-point scale mentioned above, "slight change" for the right cheek, and "somewhat clear change" for the left cheek.

[0145] After performing the operation of detecting the temporary change, the control unit 130 next estimates the degree of exposure of each monitoring target part based on the supplied temporary change information.

[0146] For example, rather than performing processing as complex as the first skin information collection and utilization system A1 described above, the degree of exposure of each monitored area may be determined in proportion to the degree of temporary change, and the degree of exposure may be estimated after processing to reduce errors due to certain factors, such as taking into account the room temperature at the time of measurement.

[0147] Here, on a five-point scale of little, slightly little, normal, slightly more, and more, the forehead and chin were rated as "little," the right cheek was "normal," and the left cheek was "slightly more."

[0148] After estimating the degree of exposure, the control unit 130 then causes the built-in speaker to emit a sound that prompts the user to switch to the treatment mode.

[0149] Then, the user U, hearing this voice, operates the mode selection button 117c to select the treatment mode, and presses the function button 117b to switch the second skin information collection and utilization system A2 to the treatment mode.

[0150] Furthermore, the user U places cotton 115 soaked in lotion on the upper surface 114a of the contact portion 114, and fixes the cotton 115 with a ring-shaped fixture (not shown).

[0151] Next, when the user U presses the function button 117b, the control unit 130 starts to pass electricity to the contact portion 114, making it ready for treatment, and then a message is given to the user U via the built-in speaker saying, "Please place the contact portion against your right cheek."

[0152] Following this guidance, the user U places the contact portion 114 against his or her right cheek, and treatment with iontophoresis begins. At this time, the estimated degree of exposure to the right cheek is "normal," so treatment is performed with a typical level of electrical current.

[0153] When the right cheek has been treated for a predetermined period of time, the control unit 130 then issues a guidance to the user U through the built-in speaker saying, "Place the contact part against your left cheek." When the user U follows this guidance and places the contact part 114 against his left cheek, a relatively stronger current is applied than the normal current applied to the right cheek, and a somewhat higher intensity treatment is performed, based on the estimated degree of exposure to the left cheek being "slightly high."

[0154] In this way, by selectively administering high intensity treatment to areas with a high estimated degree of exposure, it becomes possible to efficiently maintain the skin.

[0155] Similarly, the control unit 130 sequentially guides the user U to "Place the contact part against your chin" and "Place the contact part against your forehead." At this point, since the estimated exposure level for the "chin" and "forehead" was "low," weaker treatment is performed with a relatively weaker current than the normal current applied to the right cheek.

[0156] In this way, by selectively applying lower intensity treatment to areas with a lower estimated degree of exposure, the power consumed by the second skin information collection and utilization system A2 can be reduced, making it possible to extend the operating time of the battery-powered second skin information collection and utilization system A2, for example.

[0157] As described above, according to the second skin information collection and utilization system A2 of this embodiment, it is possible to provide a skin information collection and utilization system that is capable of inferring whether a subject has been exposed to a lot of ultraviolet rays and the areas that have been exposed to the most from temporary changes in the subject's skin, and then providing treatment.

[0158] Incidentally, with regard to the above-described second skin information collection and utilization system A2 as well, the configuration of each part may be modified as appropriate without departing from the spirit of the present invention.

[0159] For example, the above-mentioned second skin information collection and utilization system A2 is configured to be completed by a single device, but is not limited to this, and the second skin information collection and utilization system A2 may be configured together with a separate device such as a computer or smartphone connected by wire or wirelessly. In this case, the facial treatment device 100 is provided with an element state acquisition means and a treatment means, and other means constituting the second skin information collection and utilization system A2 may be left to the smartphone or computer.

[0160] Further, the above-mentioned second skin information collection and utilization system A2 is not configured to be connected to the Internet, but it may be configured to be connected and to be able to download necessary information etc. as needed.

[0161] In the above-mentioned second skin information collection and utilization system A2, the palm temperature acquisition unit 101, which is the second element state acquisition means (second temperature measurement unit), is provided on the side of the treatment device main body 112, but this is not limited to this, and for example, the temperature measurement target can be the skin of another body surface part. Also, the second element state acquisition means is provided integrally with the housing of the facial treatment device 100, but for example, a thermometer capable of wireless communication with the facial treatment device 100 can be used as the second element state acquisition means to configure the second skin information collection and utilization system A2 separately.

[0162] In addition, in the above-mentioned second skin information collection and utilization system A2, after acquiring information on the skin color and temperature conditions of all four monitored areas, temporary changes are detected and the degree of exposure is estimated, but this is not limited to this, and for example, it is also possible to detect temporary changes and estimate the degree of exposure each time the state of a specified element is acquired in the monitored areas.

[0163] Furthermore, with such a configuration, each time the state of a specific element is acquired for each monitored part, it is possible to notify the user U of the estimated result of the exposure level for that part.

[0164] Specifically, when the user U presses the function button 117b to obtain the status of a specified element, a voice message such as "The estimated degree of exposure is 'slightly low'" may be output from the built-in speaker, or the degree of exposure may be indicated by color using an indicator lamp 117d provided on the operation unit 117.

[0165] In addition, in the above-mentioned second skin information collection and utilization system A2, the treatment performed when switching to the treatment mode is treatment by iontophoresis, but this is not limited to this, and any treatment method that is expected to have the effect of maintaining beautiful skin, such as treatment by low-frequency pulse current or treatment by vibration, can be used as appropriate.

[0166] Furthermore, if the second skin information collection and utilization system A2 has a skin cooling function via the contact portion 114, the cooling function for lowering the temperature of the skin prior to treatment may be operated first, or the cooling operation time may be extended.

[0167] In addition, the skin color acquisition unit 102 of the second skin information collection and utilization system A2 may be a predetermined element built into the contact unit 114, such as an image sensor, or may be a combination of a light emitting element and a light receiving element to analyze reflected light from the skin surface, so long as it is possible to acquire at least the color state of a predetermined element of the skin, and the resolution, etc. of the element is not an issue.

[0168] However, if the skin color acquisition unit 102 is equipped with an image sensor having a pixel count sufficient to detect skin texture, blemishes, and the like, and sufficient to allow the user U or subject T to confirm the presence of skin texture or blemishes when an image is displayed, and an optical system capable of taking close-up shots of the skin surface, then it will be possible to make it easier for the subject T to check the skin condition by displaying an image, and to display and notify the results of the skin analysis, and further to further improve the accuracy of the estimation of the degree of ultraviolet exposure by the exposure degree estimation means by referring to these analysis results, as in the skin analysis image display unit 91 and skin analysis evaluation display unit 92 of the skin analysis screen 90 described above with reference to FIG. 12.

[0169] [3. The third skin information collection and utilization system] Next, the third skin information collection and utilization system A3 will be described. Fig. 15 is an explanatory diagram showing a usage state of a mirror-type user device 200 having a form like a wall-mounted mirror, which is one of the components of the third skin information collection and utilization system A3. This third skin information collection and utilization system A3 has many components in common with the first skin information collection and utilization system A1 described above, but differs in some points.

[0170] For example, the user device 15 in the first skin information collection and utilization system A1 described above is configured by connecting a skin information collection device 10 and a smartphone 11, which are separate entities, but the third skin information collection and utilization system A3 differs in that the user device is configured as an integrated wall-mounted mirror type.

[0171] In addition, the specified element of the skin to be acquired is the skin temperature state, the same as in the first skin information collection and utilization system A1, but the configuration differs in that the temperature state at each monitored area on the user U's face is acquired non-contact by thermography.

[0172] The configuration of the third skin information collection and utilization system A3 according to this embodiment will be described below. However, since the third skin information collection and utilization system A3 has much in common with the first skin information collection and utilization system A1 as described above, the description of the similar configuration will be simplified or omitted.

[0173] 16 is an explanatory diagram showing the overall configuration of the third skin information collection and utilization system A3. The third skin information collection and utilization system A3 is composed of a mirror-type user device 200, an Internet network 212, and a server device 213.

[0174] The mirror-type user device 200 functions as an element state acquiring means for acquiring the state of temperature as a predetermined element from the skin of the monitored area of ​​the user U who is the subject T, which in this embodiment is several places (forehead, left and right cheeks, chin) of the skin, and also functions as a temporary change detecting means, and further functions as a notifying means having a notifying unit that can display information such as advice on skin as an image. Moreover, the mirror-type user device 200 is essentially an information and communication terminal having the outer shape of a mirror, and a control unit 203 described later is configured to be able to execute programs such as various applications.

[0175] Fig. 17 is an explanatory diagram showing the configuration of the mirror-type user device 200. As shown in Fig. 17, the mirror-type user device 200 is configured by arranging a mirror 202 over the entire surface inside a ring-shaped frame 201. In addition, the rear side of the mirror 202 houses a control unit 203 that is responsible for the overall control of the mirror-type user device 200, and a thermography unit 207 that visualizes the temperature distribution of the body surface of a user U through an image, and is configured to be able to measure the overall skin temperature of the user U's face.

[0176] Further, at the upper portion of the edge frame 201, a lens portion 204 of a thermography unit 207 and a front camera 216f are disposed so as to be directed toward the face of the user U.

[0177] In addition, a human sensor 206 is provided at the bottom of the edge frame 201, making it possible to detect the approach of a person to the mirror type user device 200.

[0178] In addition, a liquid crystal display 205 capable of displaying an image is provided on the rear surface of the mirror 202. When an image is displayed on the liquid crystal display 205, the displayed image can be seen through the mirror 202. However, when no image is displayed, the liquid crystal display 205 is not visible and functions as a mirror, so that the portion of the mirror 202 facing the liquid crystal display 205 is configured as a so-called magic mirror (one-way mirror).

[0179] A touch pad is provided in this magic mirror portion to form a touch panel together with the liquid crystal display 205, allowing the user U to make predetermined inputs by touching it.

[0180] The mirror 202 also functions as a visible light image presenting means capable of presenting a visible light image of substantially the entire face of the user U in the mirror-type user device 200. In other words, the mirror 202 makes it possible to visually recognize the visible light image of the user U when photographed by the thermography device.

[0181] As shown in FIG. 16, the mirror type user device 200 is capable of transmitting and receiving information to and from a server device 213 via the Internet network 212 .

[0182] The mirror-type user device 200 also functions as aging factor onset prediction means for predicting the onset of skin aging factors such as blemishes and wrinkles on various parts of the face, similar to the above-mentioned first skin information collection and utilization system A1, based on information regarding the degree of exposure to ultraviolet rays estimated by the server device 213, and also functions as a notification information generating unit for generating an image including notification information regarding beauty based on the prediction of the onset of aging factors, i.e., an image for displaying on the liquid crystal display 205 to notify the user U of the beauty information. These functions are also realized by an application executed in the control unit 203.

[0183] Incidentally, the internet network 212 and the server device 213 have substantially the same configurations as the internet network 12 and the server device 13 of the first skin information collection and utilization system A1, and therefore a description thereof will be omitted.

[0184] Next, the use procedure and processing flow of the third skin information collection and utilization system A3 having such a configuration will be described while assuming a somewhat concrete scenario. The third skin information collection and utilization system A3 will also be described assuming a case where the subject T is the user U. The user U has already started using the third skin information collection and utilization system A3 on a daily basis, and a temperature distribution image (normal skin temperature distribution image) of the user U taken by a thermography device when not affected by ultraviolet rays has already been stored in a memory area provided inside the mirror-type user device 200. Note that the areas to be monitored are set to four locations on the face, namely the forehead, left and right cheeks, and chin, as in the first skin information collection and utilization system A1 described above.

[0185] When the user U who has returned home from outside returns to his / her room and approaches the mirror-type user device 200 , the human presence sensor 206 detects the user U, and the control unit 203 starts the start-up operation of the mirror-type user device 200 .

[0186] Next, the control unit 203 displays on the liquid crystal display 205 a message as to whether or not to start acquiring the skin temperature state, and waits for an input from the user U.

[0187] When user U touches a start button displayed on liquid crystal display 205 via the touch pad and positions substantially his / her entire face in a predetermined position while looking at mirror 202, thermography unit 207 is activated to capture an image of user U's entire face via lens section 204 and generate a facial temperature distribution image. In addition, front camera 216f is activated to capture an image of user U's face (visible light image).

[0188] Next, the control unit 203 refers to a normal skin temperature distribution image stored in advance in a specified memory area, and compares it with the acquired temperature distribution image to detect temporary changes caused by ultraviolet rays in each monitored area, and determines the extent of the changes.

[0189] After performing the operation of detecting the temporary change, control unit 203 then transmits information (temporary change information) regarding the location and degree of the temporary change detected by the temporary change detection means to server device 213 via Internet network 212.

[0190] The server device 213, which receives the temporary change information supplied via the Internet 12, estimates the degree of exposure while referring to the information on the observation results of the amount of ultraviolet light obtained from the Internet and various other information. The information on the estimated degree of exposure is transmitted to the mirror-type user device 200 of the user U via the Internet 212.

[0191] The mirror-type user device 200, having received the estimated information on the degree of exposure, then displays each image, such as a calendar image, on the liquid crystal display 205, in a manner generally similar to the first skin information collection and utilization system A1 described above, and provides the user U with information regarding their skin.

[0192] For example, the control unit 203 functions as a notification information generating unit, and generates a calendar image together with the estimated exposure degree result, using information on the amount of ultraviolet rays in a predetermined area (for example, information on the amount of ultraviolet rays at home) acquired via the Internet network 212. The generated calendar image is an image as shown in Fig. 5, and is displayed on the liquid crystal display 205, which is a notification unit.

[0193] Based on the estimated information on the degree of exposure, a screen similar to the daily report image, information display screen, and future face display screen is displayed. Note that compared to the calendar image 30, daily report image 40, information display screen 50, future face display screen 60, etc. of the first skin information collection and utilization system A1, location information and other missing information are not displayed.

[0194] Furthermore, the third skin information collection and utilization system A3 of this embodiment can also provide a skin information collection and utilization system that can infer whether the subject T, who is the user U, has been exposed to a lot of UV rays and which parts of the body have been exposed to the most UV rays from temporary changes in the skin, and can provide advice.

[0195] In particular, since the mirror-type user device 200 is employed, the user U can easily check his / her skin when checking his / her appearance, and can keep his / her skin beautiful.

[0196] Incidentally, with regard to the above-described third skin information collection and utilization system A3 as well, the configuration of each part may be modified as appropriate without departing from the spirit of the present invention.

[0197] As described above, the first skin information collection and utilization system according to the present embodiment is a skin information collection and utilization system that provides treatment and / or information according to the acquired state of a predetermined element of the skin of a monitored area of ​​a subject, and includes at least one of a treatment unit that performs skin treatment and a treatment control unit that controls the intensity of treatment of the treatment unit based on the degree of exposure to ultraviolet rays estimated to have been received by the skin, and a notification unit that notifies information about the skin and a notification information generation unit that generates notification information to be supplied to the notification unit based on the degree of exposure to ultraviolet rays estimated to have been received by the skin, and the skin information collection and utilization system includes at least one of a treatment unit that performs treatment and a treatment control unit that controls the intensity of treatment of the treatment unit based on the degree of exposure to ultraviolet rays estimated to have been received by the skin, and the skin information collection and utilization system provides treatment and / or information according to the acquired state of a predetermined element of the skin of a monitored area of ​​a subject, The system includes a temporary change detection means for comparing the state of a specific element acquired by the element state acquisition means with the past states of the specific element to detect a temporary change in the state of the specific element of the skin in the monitored area, and an exposure degree estimation means for estimating the degree of ultraviolet light exposure of the skin in the monitored area based on the degree of the temporary state change detected by the temporary change detection means, and treatment is administered by the treatment means and / or information is provided by the notification means based on the degree of ultraviolet light exposure estimated by the exposure degree estimation means, so that a skin information collection and utilization system can be provided that can infer whether a subject has been exposed to a lot of ultraviolet light and the areas that have been exposed to the most from temporary changes in the skin, and can provide treatment or advice.

[0198] Finally, the above-mentioned embodiments are merely examples of the present invention, and the present invention is not limited to the above-mentioned embodiments. Therefore, even if the above-mentioned embodiments are different, various modifications can be made depending on the design, etc., as long as they do not deviate from the technical idea of ​​the present invention.

[0199] In particular, the configuration mentioned in the description of any of the first skin information collection and utilization system A1 to the third skin information collection and utilization system A3 can be applied to the other systems of the first skin information collection and utilization system A1 to the third skin information collection and utilization system A3, as long as it does not deviate from the technical idea of ​​the present invention, and is naturally included in the present invention. Therefore, the fact that a configuration described in an embodiment of one skin information collection and utilization system is not described as a configuration of an embodiment of another skin information collection and utilization system does not prevent the applicant from adding the configuration when patenting the other skin information collection and utilization system, a skin information utilization system of a higher concept including each embodiment, or an invention related thereto. However, when patenting the one skin information collection and utilization system, a skin information utilization system of a higher concept including each embodiment, or an invention related thereto, the applicant also does not prevent the omission of the configuration based on the fact that it is not described as a configuration of an embodiment of another skin information utilization system.
