5 is a graph showing the color space of CIE 1931. In FIG. 5, the horizontal axis represents the x coordinate of the CIE, and the vertical axis represents the y coordinate of the CIE. The z-coordinate of the CIE can be calculated as 1- (x + y).

Referring to FIG. 5, the range RG is indicated. The range RG indicates that x is within 0.3 and y is within 0.2.

Even when the white light emitted from the white light emitting device 132 (see FIG. 4) is adjusted, when x is greater than 0.3 and y is greater than 0.2, the mixed light of the white light and the ultraviolet light is colored by the white light included in the ultraviolet light itself.

6 is a graph illustrating x, y, and z coordinates of mixed light according to the plurality of modes MD1 to MD16. In the first to sixteenth modes MD1 to MD16, the intensity of the ultraviolet light of the ultraviolet light emitting device 131 (see FIG. 4) is fixed, and the intensity of the white light of the white light emitting device 132 (see FIG. 4) is sequentially increased. do. The graph of FIG. 6 may be the result obtained by placing an optical fiber in an area corresponding to the focus lens 140.

Referring to FIG. 6, as the intensity of the white light increases, the x coordinate, the y coordinate, and the z coordinate change approximately linearly. As the intensity of the white light increases, the x coordinate may increase, the y coordinate may increase, and the z coordinate may decrease. For example, the x-coordinate is represented by the function 0.0033m + 0.1966 depending on the mode, the y-coordinate is represented by the function 0.0086 * m + 0.0761 depending on the mode, and the z-coordinate is represented by the function -0.0119 * m + 0.7273 by the mode. (M is the mode). The functions of the x, y, and z coordinates are indicated by dotted lines.

The linear change in the color coordinates of the mixed light means that the color coordinates of the incident light transmitted by the mixed light is reflected on the skin. Accordingly, an image that the mobile 10 can take in the first to sixteenth modes MD1 to MD16 may be changed. Referring to FIG. 5, the movement (MV) of the x- and y-coordinates of the mixed light is shown when the intensity of the white light increases. The movement (MV) shows that as the intensity of white light increases, the color of the mixed light moves in the white direction in the color space of CIE 1931.

In an embodiment, since the color coordinates of the mixed light linearly change in each of the modes MD1 to MD16, the mobile 10 may have sebum, wrinkles, pigments, blotch, sunscreen, acne, pores, erythema, Atopic dermatitis, psoriasis, skin conditions, skin problems, and the like can be photographed.

An embodiment of the present invention is not limited to the number of modes MD1 to MD16. For example, two modes MD1 to MD2 may be provided. In the first mode MD1, one of sebum, wrinkles, pigments, blotch, and sunscreen remains may be photographed, and in the second mode MD2, one of acne, pores, erythema, atopy, and psoriasis may be photographed. .

The light sensor 380 detects light reflected from the skin. The optical sensor 380 may be a sensor that detects at least one of ultraviolet light and visible light. In addition, the optical sensor 380 may quantify the detected light.

When the skin is irradiated with ultraviolet rays, the sunscreen reflects the ultraviolet rays. In addition, sebum excites and reflects ultraviolet rays green-yellow. In addition, acne bacteria excite ultraviolet rays in red and reflect them.

Therefore, the skin measuring apparatus 300 may determine the skin condition by detecting and quantifying the light reflected by the optical sensor 380 as well as the skin photographing.

For example, the optical sensor 380 may be a sensor that detects ultraviolet rays. In this case, the skin measuring apparatus 300 may detect the sunscreen remaining on the skin through the light sensor 380 and quantify the amount of sunscreen remaining.

Alternatively, the light sensor 380 may be a sensor that detects green light. In this case, the skin measuring apparatus 300 may detect sebum of the skin through the light sensor 380 and quantify the amount of sebum. The skin measurement apparatus 300 may determine skin types such as dryness and oiliness through the quantified amount of sebum. In addition, the skin measuring apparatus 300 may determine the degree of aging of the pores or skin through the color change around the sebum.

In addition, the skin measurement apparatus 300 may distinguish the skin color type through the light sensor 380. Depending on the color of the skin, the degree of reflection of ultraviolet rays is different. Therefore, the skin measuring apparatus 300 may determine the skin color type by quantifying the amount of ultraviolet light absorbed or reflected from the skin through the optical sensor 380.

As described above, the skin color type determined by the light sensor 380 may be determined by a user using the skin measurement apparatus 300 to determine a safe exposure time for UV exposure according to the skin color type, a cutoff index of an appropriate sunscreen according to the skin color type, and the like. Can be a standard.

Alternatively, the skin measuring apparatus 300 may store information on the UV exposure time and the blocking index of the sunscreen according to the skin color type in advance. In this case, the skin measuring apparatus 300 may measure the skin color type and automatically display information on the UV exposure time, UV cut index, etc. according to the skin color type through a mobile or the like. Furthermore, the skin measurement apparatus 300 may be used to determine the vitamin D recommended intake of the individual by using the skin color type or the amount of ultraviolet rays reflected from the skin.

That is, as shown in FIG. 12, the skin measurement mode may select various modes such as sebum, acne, pores, wrinkles, sunscreen, and pigment / mushroom. Here, the skin measurement mode is the skin measurement mode of the interface 290 described in the block diagram of FIG. 9. In an embodiment of the invention, the skin measurement mode is associated with the light sensor 380. That is, when one of the skin measurement modes is selected, the light sensor 380 connected to the mode may detect and quantify the light reflected from the skin.

For example, when measuring the presence of sunscreen, by selecting the sunscreen mode, the light sensor for detecting ultraviolet light can detect and quantify the light reflected from the skin.

As such, the skin measurement apparatus 300 according to the exemplary embodiment may measure various types of skin conditions in one apparatus through various optical sensors 380.

13 and 14 are exemplary views illustrating a method of determining skin aging according to the skin measuring apparatus of FIG. 11.

13 is a scalp photographed using the skin measurement apparatus 300. On the left is a healthy scalp picture, and on the right is a picture of hair loss due to aging of the scalp.

Comparing healthy scalp and scalp that has advanced hair loss, you can see that there are more areas with different color on the scalp. In other words, it can be confirmed that the hair loss progression scalp photo has a different color area than the scalp pores than the healthy scalp photo. Ultraviolet rays irradiated to the skin or mixed light of ultraviolet rays and white light are excited by the sebum, and the reflected portion appears in a different color from the scalp.

In other words, it is possible to check the size of a larger number of sebum and larger sebum than a healthy scalp in a scalp that has undergone hair loss.

The skin measurement apparatus 300 may quantify the portion of the skin having the color different from the light reflected from the skin by photographing the skin through the optical sensor 380.

14 is a graph showing the area of skin color change with age. Here, the color change area of the skin is a value obtained by quantifying a portion in which a different color appears around the pores in comparison with healthy pores through the skin measuring apparatus 300. Here, the healthy pores may be healthy pores in the 20s. Alternatively, the healthy pores may be the healthy pores of the measurer himself.

In addition, the skin measuring apparatus 300 may determine the degree of aging by comparing the quantified value with a preset reference value. The reference value may be set in advance in the skin measurement apparatus 300 as the color change area of the healthy pores.

Referring to FIG. 14, it can be seen that the area of color change increases with a dotted line with age. The dotted line is an average value of the color change area with age. That is, the dotted line may be referred to as the average value of the color change area of a predetermined range around the pores or the entire skin as compared to healthy pores. Here, the color change area represents an area of a part having a color different from that of the skin when the skin or the scalp is photographed through the skin measuring apparatus 300. That is, the color change area is a value obtained by detecting sebum of the skin through the light sensor 380 of the skin measuring apparatus 300 and quantifying the amount of sebum.

According to an embodiment of the present disclosure, the skin of the subject may be photographed through the skin measuring apparatus 300 including the optical sensor 380, and the color change area may be calculated. In addition, the degree of skin aging may be determined through a graph showing the calculated color change area and the color change area according to age.
