[0001] The present invention relates to a skin diagnosis system, a skin diagnosis device, a program, and a method.

[0002] It is known that the condition of the surface of the skin is diagnosed using, for example, an image of the skin.

[0003] JP 2014-219781 A

[0004] However, it has been desired to be able to diagnose not only the surface condition of a user's skin, but also the internal condition of the user's skin, which will affect the future condition of the skin.

[0005] Therefore, an object of the present invention is to improve skin diagnosis.

[0006] A skin diagnosis system according to one embodiment of the present invention is a skin diagnosis system including a terminal and a server, and is equipped with a skin condition acquisition unit that acquires a user's skin condition, a blood vessel condition acquisition unit that acquires the user's blood vessel condition, and a skin index calculation unit that calculates the user's skin index based on the acquired skin condition and the acquired blood vessel condition.

[0007] The present invention allows for improved skin diagnosis.

[0009] Hereinafter, an embodiment of the present invention will be described with reference to the drawings.

[0010] <Explanation of Terms> In this specification, "skin condition" refers to the surface condition of a person's facial skin (i.e., the current appearance of the skin). For example, skin conditions include "blood circulation," "wrinkles, sagging," and "skin irregularities." In this specification, "skin index" refers to an index of a person's facial skin factor (skin element). In the present invention, a skin index can be calculated based not only on the skin condition (i.e., the current appearance of the skin) but also on the internal condition of the skin (specifically, the state of blood vessels), which will affect the skin in the future. For example, "skin index" refers to "transparency," "firmness / elasticity," and "smoothness."

[0011] <Overall Configuration Example> FIG. 1 shows an overall configuration example according to one embodiment of the present invention.

[0012] [Configuration Example 1] The skin diagnosis system 1 includes a skin diagnosis device (e.g., a server) 10 and a terminal 11. The skin diagnosis device 10 and the terminal 11 are communicably connected via an arbitrary network. In Configuration Example 1, a user 20 (or a beauty consultant at a cosmetics store, etc.) operates the terminal 11. Each of these will be described below.

[0013] <<Skin Diagnostic Device>> The skin diagnostic device 10 is a device that calculates skin indices of a user 20 based on the skin condition and blood vessel condition of the user 20. For example, the skin diagnostic device 10 is a server or the like made up of one or more computers.

[0014] <<Terminal>> The terminal 11 acquires the skin condition and blood vessel condition of the user 20 and transmits them to the skin diagnostic device 10, and receives and displays the results of the diagnosis made by the skin diagnostic device 10. Note that the terminal 11 may execute part of the processing of the skin diagnostic device 10 described in this specification.

[0015] For example, the terminal 11 transmits to the skin diagnosis device 10 an image of the facial skin of the user 20 taken by the camera function for photography, data on the temperature of the facial skin of the user 20 acquired by the thermography camera (also called a thermo camera or a thermistor camera) function, and the user 20's responses to a medical interview (questionnaire regarding the skin condition).

[0016] For example, terminal 11 may be a smart mirror installed in a store (specifically, a display equipped with a camera function for taking pictures and a thermography camera function), a smartphone equipped with a camera function for taking pictures and a thermography camera function, a tablet equipped with a camera function for taking pictures and a thermography camera function, etc. Note that terminal 11 that does not have a camera function for taking pictures and a thermography camera function may also acquire facial skin images and facial skin temperature data captured and acquired by a device equipped with a camera function for taking pictures and a thermography camera function.

[0017] Configuration Example 2 In configuration example 2, a user 20 (or a beauty consultant at a cosmetics store, etc.) operates the skin diagnostic device 10 .

[0018] <<Skin Diagnostic Device>> The skin diagnostic device 10 is a device that calculates skin indices of a user 20 based on the skin condition and blood vessel condition of the user 20. For example, the skin diagnostic device 10 is a smart mirror installed in a store (specifically, a display equipped with a camera function for taking pictures and a thermography camera function), a smartphone equipped with a camera function for taking pictures and a thermography camera function, a tablet equipped with a camera function for taking pictures and a thermography camera function, etc. Note that a skin diagnostic device 10 that does not have a camera function for taking pictures and a thermography camera function may also acquire facial skin images and facial skin temperature data captured and acquired by a device equipped with a camera function for taking pictures and a thermography camera function.

[0019] 2 is a functional block diagram of a skin diagnostic device 10 according to an embodiment of the present invention. The skin diagnostic device 10 includes a skin condition acquisition unit 101, a blood vessel condition acquisition unit 102, a skin index calculation unit 103, a skin index presentation unit 104, a recommendation determination unit 105, a recommendation presentation unit 106, and a recommendation information storage unit 107. The skin diagnostic device 10 executes a program to function as the skin condition acquisition unit 101, the blood vessel condition acquisition unit 102, the skin index calculation unit 103, the skin index presentation unit 104, the recommendation determination unit 105, and the recommendation presentation unit 106.

[0020] The skin condition acquisition unit 101 acquires the skin condition (e.g., the condition of the skin surface) of the user 20. For example, the skin condition acquisition unit 101 evaluates the skin condition of the user 20 based on at least one of an image of the facial skin of the user 20, the temperature of the facial skin of the user 20, and the user's 20 response to a medical interview (a questionnaire regarding the skin condition), and can use the skin condition.

[0021] [Skin Condition] Here, the skin condition will be described. For example, the skin condition may be at least one of "blood circulation" evaluated based on skin temperature and responses to a medical interview, "wrinkles and sagging" evaluated by analyzing an image of the skin, and "skin irregularities" evaluated by analyzing an image of the skin. For example, the skin condition may be a numerical score.

[0022] The vascular condition acquisition unit 102 acquires the vascular condition of the user 20. For example, the vascular condition acquisition unit 102 acquires skin information (e.g., the number of blemishes, TEWL (transepidermal water loss), redness, yellowness, skin groove area ratio, unevenness of skin texture, pore area ratio, collagen density, etc.) from an image of the facial skin of the user 20, and inputs the skin information into a model (e.g., a trained model that has been machine-learned using backpropagation or the like so that the vascular condition is output when skin information is input), thereby acquiring the vascular condition.

[0023] [Blood Vessel Condition] Here, the blood vessel condition will be described. For example, the blood vessel condition is at least one of the capillary blood flow, the number of capillaries, the density of capillaries, the number of capillary branches, the distance from the base of the epidermis to the capillaries, and the thickness of the epidermis. For example, the blood vessel condition may be a numerical score. In the present invention, by using the internal condition of the skin (specifically, the blood vessel condition), which also affects the future skin condition, it is possible to diagnose the skin taking into account not only the surface condition of the skin (i.e., the current appearance of the skin) but also the future skin condition.

[0024] The skin index calculation unit 103 calculates the skin index of the user 20 (for example, a score that quantifies "transparency," "firmness / elasticity," and "smoothness") based on the skin condition acquired by the skin condition acquisition unit 101 and the blood vessel condition acquired by the blood vessel condition acquisition unit 102.

[0025] For example, the skin index calculation unit 103 can switch the way of calculating the skin index of the user 20 depending on whether the vascular condition of the user 20 is outside a predetermined range (e.g., when the vascular condition is inappropriate) or when the vascular condition of the user 20 is within a predetermined range (e.g., when the vascular condition is appropriate).

[0026] [Predetermined Range of Blood Vessel Condition] The predetermined range of blood vessel condition will now be described. For example, the predetermined range of blood vessel condition is a range in which the blood vessel condition is appropriate.

[0027] The skin index calculation unit 103 can set a predetermined range. For example, the skin index calculation unit 103 can set a predetermined range for each attribute information such as age or generation, sex, region, lifestyle (e.g., mostly spends time outdoors, mostly spends time indoors, etc.).

[0028] For example, the skin index calculation unit 103 can set a value input by the user 20 or the like as a predetermined range. For example, the skin index calculation unit 103 can set a value input by the user 20 or the like for each piece of attribute information as a predetermined range.

[0029] For example, the skin index calculation unit 103 can set a range that includes the median of the vascular condition values ​​of multiple people (i.e., a range that includes a certain percentage of people from the median) as the predetermined range. For example, the skin index calculation unit 103 can set, for each piece of attribute information, a range that includes the median of the vascular condition values ​​of multiple people who have the attribute information.

[0030] For example, the skin index calculation unit 103 can set a range including the median of the values ​​of the related skin conditions (i.e., a range including a certain percentage of people from the median) as the predetermined range. For example, the skin index calculation unit 103 can set a range including the median of the values ​​of the related skin conditions as the predetermined range for each piece of attribute information.

[0031] Specifically, blood vessel condition correlates with the skin condition "blemishes," and "blemishes" contribute to skin clarity. Blood vessel condition also correlates with the skin condition "wrinkles," and "wrinkles" contribute to skin firmness and elasticity. Blood vessel condition also correlates with the skin condition "TEWL (transepidermal water loss)," and "TEWL (transepidermal water loss)" contributes to skin smoothness. The following formula can be created from the correlation between blood vessel condition and "blemishes," "wrinkles," and "TEWL (transepidermal water loss)." Blood vessel condition = A × skin condition "age spots" + B Blood vessel condition = C × skin condition "wrinkles" + D Blood vessel condition = E × skin condition "TEWL (transepidermal water loss)" + F The skin index calculation unit 103 can set the predetermined range to a range that includes the blood vessel condition (when the median value of age spots is substituted), the blood vessel condition (when the median value of wrinkles is substituted), or the blood vessel condition (when the median value of "TEWL (transepidermal water loss)" is substituted), which is the result of substituting the median values ​​of multiple people for the skin conditions "age spots," "wrinkles," and "TEWL (transepidermal water loss)."

[0032] [When the blood vessel condition is outside the predetermined range] When the blood vessel condition is outside the predetermined range, the skin index calculation unit 103 calculates the skin index of the user 20 based on the skin condition acquired by the skin condition acquisition unit 101 and the blood vessel condition acquired by the blood vessel condition acquisition unit 102. For example, the skin index calculation unit 103 adds or subtracts points according to the score of the blood vessel condition (specifically, the skin index (transparency) = "blood circulation (skin condition evaluated based on skin temperature and responses to a medical interview)" + α1 × blood vessel condition score, skin index (firmness / elasticity) = "wrinkles, sagging (skin condition evaluated by analysis of skin images)" + α2 × blood vessel condition score, skin index (smoothness) = "skin unevenness (skin condition evaluated by analysis of skin images)" - α3 × blood vessel condition score) to calculate each index.

[0033] Note that α1, α2, and α3 may each be a different constant. For example, the magnitude and sign of α1, α2, and α3 can be determined according to the degree of correlation between the skin factors underlying each skin index and the vascular condition (for example, the correlation between each skin factor, such as age spots, wrinkles, and TEWL (transepidermal water loss) described below, and the vascular condition). For example, if the degree of correlation with the vascular condition is high, α1, α2, and α3 are large, and if the degree of correlation with the vascular condition is low, α1, α2, and α3 are small. Furthermore, if there is a positive correlation with the vascular condition, α1, α2, and α3 are positive, and if there is a negative correlation with the vascular condition, α1, α2, and α3 are negative.

[0034] For example, a high score for blood vessel condition (e.g., fast blood flow) corresponds to a high score for blemishes (i.e., few or light blemishes), whereas a low score for blood vessel condition (e.g., slow blood flow) corresponds to a low score for blemishes (i.e., many or dark blemishes). This shows that blood flow speed contributes to skin clarity.

[0035] For example, a high blood vessel condition score (e.g., fast blood flow) corresponds to a high wrinkle score (i.e., fewer, shallower wrinkles), while a low blood vessel condition score (e.g., slow blood flow) corresponds to a low wrinkle score (i.e., more, deeper wrinkles). This shows that blood flow speed contributes to skin firmness and elasticity.

[0036] For example, a high blood vessel condition score (e.g., fast blood flow) corresponds to a low TEWL (transepidermal water loss) score (i.e., dry skin), whereas a low blood vessel condition score (e.g., slow blood flow) corresponds to a high TEWL (transepidermal water loss) score (i.e., moist skin). This shows that blood flow speed contributes to skin smoothness.

[0037] [When the blood vessel condition is within a predetermined range] When the blood vessel condition is within a predetermined range, the skin index calculation unit 103 calculates the skin index of the user 20 based on the skin condition acquired by the skin condition acquisition unit 101. For example, the skin index calculation unit 103 adds points to all skin indices (specifically, adds β to the following: skin index (transparency) = "blood circulation (skin condition evaluated based on skin temperature and responses to a medical interview)" + β, skin index (firmness / elasticity) = "wrinkles, sagging (skin condition evaluated by analysis of a skin image)" + β, skin index (smoothness) = "skin unevenness (skin condition evaluated by analysis of a skin image)" + β) to calculate each index. Note that β is an arbitrary constant.

[0038] The skin index presentation unit 104 presents the skin index calculated by the skin index calculation unit 103 (for example, displays it on the skin diagnosis device 10 or the terminal 11). For example, the skin index presentation unit 104 can present the contribution of the blood vessel condition to the skin index. For example, the skin index presentation unit 104 can present the contribution of the blood vessel condition to the skin index in a display format corresponding to the skin condition acquired by the skin condition acquisition unit 101 and the blood vessel condition acquired by the blood vessel condition acquisition unit 102.

[0039] The recommendation determination unit 105 can determine a recommendation to be recommended to the user 20 based on both the skin condition acquired by the skin condition acquisition unit 101 and the blood vessel condition acquired by the blood vessel condition acquisition unit 102. Alternatively, the recommendation determination unit 105 can determine a recommendation to be recommended to the user 20 based only on the skin condition acquired by the skin condition acquisition unit 101, and a recommendation to be recommended to the user 20 based on both the skin condition acquired by the skin condition acquisition unit 101 and the blood vessel condition acquired by the blood vessel condition acquisition unit 102. The user 20 can select whether to determine a recommendation based only on the skin condition or to determine a recommendation based on both the skin condition and the blood vessel condition, and input an instruction to the skin diagnosis device 10 or the terminal 11.

[0040] The recommendation presentation unit 106 presents the recommendations determined by the recommendation determination unit 105 to the user 20 (for example, by displaying them on the skin diagnosis device 10 or the terminal 11).

[0041] The recommendation information storage unit 107 stores one or more pieces of recommendation information according to the skin condition and the blood vessel condition. Note that the recommendation information storage unit 107 may store recommendations based only on the skin condition and recommendations based on both the skin condition and the blood vessel condition.

[0042] 3 shows an example of information stored in the recommendation information storage unit 107 according to one embodiment of the present invention. The recommendation information storage unit 107 stores one or more pieces of recommendation information according to skin conditions and blood vessel conditions. Each of these will be described below.

[0043] "Skin condition" refers to the skin condition (for example, good (◯), bad (X)) such as clarity (blood circulation), firmness / elasticity (wrinkles, sagging), smoothness (irregularities in the skin), etc.

[0044] "Blood vessel condition" refers to the condition of blood vessels such as capillaries (for example, fast blood flow speed, appropriate blood flow speed, slow blood flow speed).

[0045] A "recommendation" is at least one of a product (e.g., a cosmetic product) and a service (e.g., a beauty service) suitable for a user 20 in a state where the skin condition acquired by the skin condition acquisition unit 101 is stored in "skin condition" and the blood vessel condition acquired by the blood vessel condition acquisition unit 102 is stored in "blood vessel condition." For example, multiple recommendations may be stored in order of suitability for the user 20.

[0046] The recommendation information storage unit 107 may store recommendations based only on the skin condition and recommendations based on both the skin condition and the blood vessel condition.

[0047] <Display Examples> Examples of screens displayed on the skin diagnostic device 10 or the terminal 11 will be described below.

[0048] Fig. 4 shows an example of the display of the results of skin index calculation according to one embodiment of the present invention. For example, the skin index presentation unit 104 can display the skin indices (e.g., translucency, firmness / elasticity, and smoothness) of the user 20 calculated by the skin index calculation unit 103 based on the skin condition and blood vessel condition of the user 20, as shown in Fig. 4. In the example of Fig. 4, the values ​​of each index (i.e., translucency: 75, firmness / elasticity: 81, smoothness: 34) and a triangular graph representing the value of each index are displayed.

[0049] 5 shows an example of a display of the results of calculation of skin indices according to an embodiment of the present invention, in which the contribution of the blood vessel condition to the skin indices of the user 20 is displayed (Example 1).

[0050] For example, the skin index presentation unit 104 can display the skin indices (e.g., transparency, firmness / elasticity, smoothness) of the user 20 calculated by the skin index calculation unit 103 based on the skin condition and blood vessel condition of the user 20, and the contribution of the blood vessel condition to each index, as shown in Fig. 5. In the example of Fig. 5, the value of each index (i.e., transparency: 75, firmness / elasticity: 81, smoothness: 34) and a triangular graph representing the value of each index are displayed. Furthermore, Fig. 5 displays the degree of contribution of the blood vessel condition to each index using arrows (in the example of Fig. 5, it is shown that the transparency value is reduced due to the blood vessel condition (i.e., it would be greater than 75 if there was no influence of the blood vessel condition), the firmness value is increased due to the blood vessel condition (i.e., it would be less than 81 if there was no contribution of the blood vessel condition), and the smoothness value is reduced due to the blood vessel condition (i.e., it would be greater than 34 if there was no influence of the blood vessel condition)).

[0051] 6 shows an example of a display of the results of calculation of skin indices according to an embodiment of the present invention, in which the contribution of the blood vessel condition to the skin indices of the user 20 is displayed (Example 2).

[0052] For example, the skin index presentation unit 104 can display the skin index of the user 20 (for example, the index value of one of transparency, firmness / elasticity, and smoothness) calculated by the skin index calculation unit 103 based on the skin condition and blood vessel condition of the user 20, and the contribution of the blood vessel condition to each index, as shown in Figure 6.

[0053] In Figure 6, (1) indicates a high skin condition score and a high blood vessel condition score. (2) indicates a high skin condition score and a low blood vessel condition score. (3) indicates a low skin condition score and a low blood vessel condition score. (4) indicates a low skin condition score and a high blood vessel condition score.

[0054] In Fig. 6, the contribution of the blood vessel condition to the skin index is displayed using a bar graph. In the bar graph of Fig. 6, (1) indicates that the skin condition score is high (i.e., the current skin appearance is good). (2) indicates that the skin condition score is high (i.e., the current skin appearance is good), but that the skin condition is at risk when the blood vessel condition is taken into account and the degree of risk. (3) indicates that the skin condition score is low (i.e., the current skin appearance is poor), and that the blood vessel condition contributes to the current skin appearance and the degree of contribution. (4) indicates that the skin condition score is low (i.e., the current skin appearance is poor). In this way, it is possible to present that even if the current skin appearance is good, the skin condition is at risk when the blood vessel condition is taken into account, as in (2), or to present the contribution of the blood vessel condition to the current poor skin appearance, as in (3).

[0055] 5 and 6, the skin index presenting unit 104 can present the contribution of the blood vessel condition to the skin index. Furthermore, as shown in Fig. 6, the skin index presenting unit 104 can present the contribution of the blood vessel condition to the skin index in a display mode corresponding to the skin condition acquired by the skin condition acquiring unit 101 and the blood vessel condition acquired by the blood vessel condition acquiring unit 102.

[0056] An example of displaying the blood vessel condition will be described below with reference to Figures 7 and 8. For example, let us assume that the score based on the blood flow speed of capillaries, etc. is as follows: If the score based on the blood flow speed is 100 to 70, it is blood vessel type A; If the score based on the blood flow speed is 70 to 40, it is blood vessel type B; If the score based on the blood flow speed is 40 to 0, it is blood vessel type C. Since the score representing the blood vessel condition should not be too high or too low, by visually displaying it as shown in Figures 7 and 8, the blood vessel condition can be presented in a way that is easy for the user 20 to understand.

[0057] 7 shows an example of a blood vessel condition display according to an embodiment of the present invention. For example, the skin index presentation unit 104 can display a plurality of blood vessel conditions (blood vessel types) by changing the diagram that resembles the blood vessels.

[0058] For example, the skin index presentation unit 104 can use three diagrams such as those in Figure 7 to display that the user 20 is a type with a fast blood flow rate in blood vessels such as capillaries (vascular type A), that the user 20 is a type with an appropriate blood flow rate in blood vessels such as capillaries (vascular type B), and that the user 20 is a type with a slow blood flow rate in blood vessels such as capillaries (vascular type C).

[0059] 8 shows an example of a blood vessel condition display according to an embodiment of the present invention. For example, the skin index presenting unit 104 can display multiple blood vessel conditions (blood vessel types) by changing the length or thickness of the arrow.

[0060] For example, the skin index presentation unit 104 can display a long arrow if the user 20 is a type with a fast blood flow rate in blood vessels such as capillaries (vascular type A), a medium-length arrow if the user 20 is a type with an appropriate blood flow rate in blood vessels such as capillaries (vascular type B), and a short arrow if the user 20 is a type with a slow blood flow rate in blood vessels such as capillaries (vascular type C).

[0061] For example, the skin index presentation unit 104 can display a thick arrow if the user 20 is a type with a fast blood flow rate in blood vessels such as capillaries (vascular type A), a medium-thick arrow if the user 20 is a type with an appropriate blood flow rate in blood vessels such as capillaries (vascular type B), and a thin arrow if the user 20 is a type with a slow blood flow rate in blood vessels such as capillaries (vascular type C).

[0062] <Method> FIG. 9 is a flowchart of a skin diagnosis process according to an embodiment of the present invention.

[0063] In step 1 (S1), the skin condition acquisition unit 101 acquires the skin condition of the user 20.

[0064] In step 2 (S2), the blood vessel condition acquisition unit 102 acquires the blood vessel condition of the user 20. Note that S1 and S2 may be executed in reverse order or simultaneously.

[0065] In step 3 (S3), the skin index calculation unit 103 determines whether the blood vessel condition acquired in S2 is within a predetermined range. If it is not within the predetermined range, the process proceeds to step 4, and if it is within the predetermined range, the process proceeds to step 8.

[0066] In step 4 (S4), the skin index calculation unit 103 calculates the skin index of the user 20 based on the skin condition acquired in S1 and the blood vessel condition acquired in S2.

[0067] In step 5 (S5), the skin index presentation unit 104 presents the skin index calculated in S4 or S8 (for example, displays it on the skin diagnostic device 10 or the terminal 11).

[0068] In step 6 (S6), the recommendation determination unit 105 determines a recommendation to be recommended to the user 20 based on both the skin condition acquired in S1 and the blood vessel condition acquired in S2. Alternatively, the recommendation determination unit 105 determines a recommendation to be recommended to the user 20 based only on the skin condition acquired in S1, and a recommendation to be recommended to the user 20 based on both the skin condition acquired in S1 and the blood vessel condition acquired in S2.

[0069] In step 7 (S7), the recommendation presentation unit 106 presents the recommendation determined in S6 to the user 20 (for example, displays it on the skin diagnosis device 10 or the terminal 11).

[0070] S6 and S7 may be executed simultaneously with S4 and S5, or may be executed in the reverse order relative to S4 and S5, or may be omitted.

[0071] In step 8 (S8), the skin index calculation unit 103 calculates the skin index of the user 20 based on the skin condition acquired in S1. Then, the process proceeds to step 5.

[0072] <Effects> In this way, in one embodiment of the present invention, it is possible to diagnose not only the surface condition of the skin of the user 20, but also the internal condition of the skin of the user 20 in an integrated manner. Therefore, it is possible to recommend products and services that take into consideration not only the current appearance of the user's 20 skin but also the future condition of the skin.
