At this time, the camera unit 120 may include a lens and an imaging device for high-resolution close-up of the skin.

Next, a skin diagnosis method according to an embodiment of the present invention will be described with reference to the drawings.

The skin diagnosis method according to an embodiment of the present invention includes processing at least one of a user's skin image generated by the camera unit 120 and skin impedance sensed through the impedance sensor 122.

The processor 104 can process one of a skin image and skin impedance. The processor 104 may derive at least one of the degree of pores, flushing, and wrinkles of the user's skin through the processing of the skin image.

To this end, the processor 104 may execute at least one of a pore detection algorithm, a flush detection algorithm, and a wrinkle detection algorithm. For example, the wrinkle detection algorithm may be an algorithm based on a frangi filter. The pore detection algorithm may be an algorithm that uses blob detection through luminance ratio.

The impedance sensor 122 may measure skin impedance by measuring a voltage change according to the skin condition by passing a micro current through the skin, and derive the moisture level of the skin through the skin impedance.

The skin diagnosis method according to an embodiment of the present invention includes the step of presenting a questionnaire about the user's skin condition through the display unit 114 or the voice output unit of the user terminal. At this time, the questionnaire may be stored in the memory unit RM of the skin diagnosis apparatus according to the embodiment of the present invention.

The user terminal may present the questionnaire visually or audibly, and may be a smart phone, a laptop, a desk top, or a tablet PC, but is not limited thereto. The display unit 114 of the user terminal may include an LCD, OLED, CRT, PDP, or beam projector, but is not limited thereto.

The input unit 118 of the user terminal may include a keyboard, a mouse, a stylus pen, and a touch panel, but is not limited thereto.

The skin diagnosis method according to an embodiment of the present invention includes deriving a user's skin type by associating a questionnaire result with at least one of an analysis result of a skin image and a skin impedance.

The questionnaire that is generally used for skin diagnosis of the user may be subject to the subjective judgment of the user, so accuracy or precision for skin diagnosis may be deteriorated.

On the other hand, the skin diagnosis method according to an embodiment of the present invention improves the accuracy and reliability of a user's skin diagnosis by using at least one of a skin image analysis result and skin impedance that can improve objectivity along with a questionnaire result for skin diagnosis. I can do it.

At this time, as shown in Figure 3, the questionnaire may include a dry/intelligent questionnaire for diagnosing the degree of dryness and oiliness of the user's skin. The skin type of the user may be set as one of a dry type, a medium/complex type, and an oily type through a dryness/oiliness questionnaire, but is not limited to such a skin type.

The dry type is a type of skin that is easily dried and pulls, and may be a skin type that can generate a lot of keratin. The medium/composite type is a skin type in which different skin types appear on a single face, and may be a skin type in which oily, dry, oily and normal skin types are different depending on the skin area. The oily type is a skin type in which pores are widened and sebum is excessively secreted, and may be a skin type in which sebum, acne, and pores are excessively formed.

Since the oily type relates to a skin type in which pores are excessively generated, the skin diagnosis method according to the embodiment of the present invention can derive the degree of pores of the user according to the analysis result of the skin image by the processor 104.

The user may select questionnaires through the input unit 118 of the user terminal, and the processor 104 may derive the user's skin type and the corresponding score according to the survey result.

For example, as illustrated in FIG. 3, when a reference number or more (for example, a majority number) is selected for a specific skin type among three questionnaires, the processor 104 sets the user's skin as the specific skin type. You can set and assign scores for the specific skin types. If the user selects the view for oiliness in the first question and the second questionnaire and the view for medium/complexity in the third questionnaire, the processor 104 may set the user's skin type to two points of the oily type. The results of the questionnaire may be stored in the memory unit RM of the skin diagnosis apparatus according to the embodiment of the present invention.

At this time, the lancer can read and use a preset weight from the memory unit RM to correlate the result of the questionnaire with the degree of pores. If the weight ratio of the result of the questionnaire and the image is 50:50, since the weight illusion is 16,67 points per 1 skin type, 2 points may correspond to a weight conversion of 33.34. In addition, if the degree of pores can also be assigned between 1 and 5 points, the degree of pores may correspond to 10 points per weight.

As described above, the processor 104 adds the weight conversion score of the skin type according to the questionnaire result and the weight conversion score of the pore degree according to the analysis of the skin image, and when the sum result exceeds the reference score, the skin type of the user is finalized as an intelligence type. Can be derived.

As described above, the skin diagnosis method according to the embodiment of the present invention can derive the skin type corresponding to the user by associating the dry/intelligent questionnaire results with the degree of pores.

Meanwhile, the skin diagnosis method according to an embodiment of the present invention is a sub-category of skin types corresponding to a user, and thus derives a skin type according to whether the user has good moisture.

For example, as shown in FIG. 4, the moisture good type and the water insufficient type may be sub-categories of dry type, medium/composite type, and oily type. Alternatively, the good moisture type and the low moisture type may be set as independent categories rather than sub-categories of dry type, medium/complex type, and oily type. Various skin types shown in FIG. 4 will be described in detail later with reference to the drawings.

Meanwhile, as illustrated in FIG. 5, the questionnaire may include a moisture-related questionnaire for diagnosing whether the user's skin has good moisture. In FIG. 5, when the user selects more than a reference number of questionnaires (for example, more than a majority), the user's skin type may be set to a lack of moisture type. The water-related questionnaire of FIG. 5 corresponds to a water shortage type, but differently, a water good questionnaire or a water shortage/moisture good question may be mixed.

The skin diagnosis method according to an embodiment of the present invention may derive a skin type according to whether the user has good moisture by associating the user's skin impedance with the result of the water-related questionnaire. The amount of moisture present in the skin can be derived relatively accurately by skin impedance.

A score may be assigned according to the polling result related to moisture, and a score may also be assigned according to skin impedance. At this time, the weights related to the polling results related to moisture and the skin impedance may be preset and stored in the memory unit RM, and the weighting converting scores for the polling results related to the moisture and the weighting converting scores for the skin impedance may be derived.

The processor 104 may finally derive whether the user is a water-insufficient type or a water-good type by comparing the sum result of the weighted conversion scores with a reference value. Since the weight conversion score method was described in detail above, the description thereof is omitted.

6 shows an example of a question regarding a user's skin sensitivity. As illustrated in FIG. 6, the questionnaire may include a sensitivity-related questionnaire for diagnosing whether the user's skin is sensitive.

Through the sensitivity-related questionnaire, the user may be diagnosed as a capillary expansion skin type, a hormone-reactive type, a stress-reactive type, or an environmental-reactive type, but this classification is only an example and is not limited thereto.

The capillary-expanded skin type may be a skin type in which the symptoms of redness are more easily exacerbated depending on the temperature difference and the environment, and the tickling caused by heat is frequently felt. Permanently expanded capillaries may appear in some areas of the face.

The hormone-reactive type is a skin type that is affected by menstrual cycles, pregnancy, etc., and may cause excessive sebum secretion, resulting in reactions such as rashes.

The stress-reactive type can cause skin irritation and red skin and sensitive dermatitis due to lack of sleep and mental and physical stress.

The environmentally responsive type may be a skin type caused by strong cold, hot sunlight, and repeated use of irritating cosmetics. It can easily respond to cosmetic effects, and skin irritation to the components of cosmetics can cause frequent troubles.

Looking at the sensitivity-related questionnaire, the sensitivity may be related to the flushing of the face, so the skin diagnosis method according to the embodiment of the present invention can derive the degree of flushing of the user according to the analysis result of the skin image, and the sensitivity-related questionnaire and flushing It is possible to derive the skin type corresponding to the user by associating the degree.

In the case of the embodiment of the present invention, when at least one of the eight questionnaires in FIG. 6 is selected, the skin type of the user may be diagnosed as sensitive. The processor 104 may allocate a score to each of the selected number of questions and the degree of flushing, convert the assigned score into a weighted conversion score, and sum them to derive a user's sensitivity level.

Since the weight and the weighted conversion score were described in detail above, the description thereof is omitted.

Meanwhile, in the skin diagnosis method according to an embodiment of the present invention, even if the user does not select any sensitivity-related questionnaire, the user may be set as a sensitive skin type when the degree of flushing is greater than or equal to a reference value. In the case of skin flushing, since the result is relatively accurate according to image processing, even if there is no selection of a sensitivity-related questionnaire in which a user's subjective judgment acts, it can be diagnosed as a sensitive skin type according to an image analysis result.

Meanwhile, as illustrated in FIG. 7, the questionnaire may include a questionnaire related to wrinkles for diagnosing the degree of wrinkles on the user's skin. The skin diagnosis method according to an embodiment of the present invention may derive a user's wrinkle level according to an analysis result of a skin image, and correlate a wrinkle-related questionnaire result with a wrinkle level to derive a skin type corresponding to the user.

In the process of deriving the skin type of the user, a score according to a result of a questionnaire related to wrinkles and an image analysis result and a weight conversion score for the score can be derived, and a skin type and a degree of wrinkle for the wrinkle can be derived by adding the weight conversion score. have.

In this case, the wrinkle-related questionnaire may include a questionnaire that selects one corresponding to a user among a plurality of wrinkle degree images previously stored in the memory unit RM. That is, in the case of the question'check the degree of plural wrinkles' in FIG. 7, a plurality of pictures are displayed through the display unit 114 of the user terminal, and when the user selects one of these pictures, the points for the selected pictures are allocated It can be done.
