Description

Skin diagnostic device and its control method {APPARATUS FOR DIAGNOSING SKIN AND CONTROL METHOD THEREOF}

The present invention relates to a skin diagnostic apparatus and a control method thereof, and more particularly, to an apparatus for diagnosing skin using reflected light of ultraviolet rays and a control method thereof.

Ultraviolet rays are one of the lights included in sunlight, and are invisible light with a shorter wavelength than visible light. It can be used to burn human skin or to sterilize, but if overexposed, it can cause blemishes, freckles, wrinkles, sunburn, etc., and in severe cases, skin cancer. Since these UV rays are always present during the time of the sun, many outdoor activities are using sunscreens to prevent them.

The sunscreen is a product for preventing the above-mentioned ultraviolet rays from being directly exposed to the skin, and various products exist according to a blocking rate and a method of use, and types and related markets are continuously increasing. Furthermore, the number of components included in various cosmetic products is also increasing.

However, sunscreens are generally almost transparent when applied evenly in consideration of cosmetic aspects. Due to this, when using it, the user has a problem in that it is difficult to grasp whether it is evenly used according to the difficulty of visually checking it even when applied or sprayed on the skin.

1 is a view for explaining ultraviolet rays according to various wavelengths.

Ultraviolet rays (UV) may refer to invisible light having a wavelength shorter than that of visible light. In general, ultraviolet rays are used to burn human skin or to sterilize, but if overexposed, they can develop skin cancer.

Referring to FIG. 1, ultraviolet rays may be classified into UVA, UVB, and UBC, UVA having ultraviolet rays having a length of 320 nm or more and less than 400 nm, and UVB having ultraviolet rays having a length of 280 nm or more and less than 320 nm. , UVC may mean ultraviolet light having a wavelength of 100 nm or more and less than 280 nm.

UVA has less energy than UVB, but it can burn the skin and act on the skin's immune system, causing long-term skin damage due to skin aging. UVB can burn the skin and can cause skin irritation if overexposed. UVC can cause more chromosomal mutations than UVB, and can have a detrimental effect on living organisms, such as killing single-celled organisms.

UVA, UVB and UVC are all transmitted from the sun to the Earth, but some of the UVB and most of the UVC are absorbed by the ozone layer present in the Earth's stratosphere and do not reach the Earth's surface.

However, if UVA and some UVB are excessively exposed, it may have a bad effect on the skin, and some of the UVB and UVC that have not been absorbed by the recent destruction of the ozone layer may reach the surface. Is receiving attention as a major issue.

The most common method of sun protection is to apply or apply sunscreen to the skin of the face or the like. However, there is a problem in that it is difficult to confirm whether the sunscreen is applied without any elaboration and precision.

An embodiment of the present invention can provide a method for directly checking whether a sunscreen is properly applied to skin of a user's face or the like through a camera module including an ultraviolet camera.
