The control unit 240 controls the filter wheel 119 to continuously align the optical filters 114 of the plurality of optical filters 114 with the light source 220 in accordance with the photographing setting of the setting unit 230. [ So that it can be rotated. At this time, the control unit 240 may control the rotation of the filter wheel 119 based on the photographing speed of the photographing unit 210.

Also, the image analyzer 260 may display a reference value previously stored for each wavelength corresponding to the plurality of optical filters 114.

According to this configuration, an embodiment of the present invention can easily diagnose skin diseases and manage skin at all times easily at home using a user terminal such as a smart phone or a tablet, It can be applied to continuous skin management mentoring system by strengthening search function by database of various information such as management after treatment, kinds of skin related diseases, beauty method for current skin condition, and the like, and is increasing due to environmental or genetic factors The skin disease can be diagnosed early, and the social and economic cost due to the skin disease can be alleviated.

Hereinafter, a method for skin diagnosis and management according to an embodiment of the present invention will be described with reference to FIG.

7 is a flowchart illustrating a method for skin diagnosis and management according to an embodiment of the present invention.

The method 700 for skin diagnosis and management includes steps S701 to S701 of photographing and storing a spectral image, step S702 of driving a drive motor 140, (S703 and S704); analyzing the captured spectroscopic image (S705); outputting the analyzed spectroscopic spectrum (S706); and irradiating the light source for skin management (S707 ).

More specifically, as shown in FIG. 7, first, the zero point of the filter wheel 119 in which a plurality of optical filters 114 are formed can be adjusted (step S701). For example, the optical filter 114 having the lowest frequency band among the plurality of optical filters 114 formed on the filter wheel 119 can be positioned in a straight line with the light source 220. At this time, it is possible to adjust the horizontal polarimeter 112 and the optical filter 114 or the magnifying glass 116 and the vertical polarimeter 118 to be positioned on a straight line with respect to the photographing unit 210 or the light source 220 of the user terminal 200 have.

Next, spectroscopic images of different wavelengths can be captured and stored using any one of the plurality of optical filters 114 of the portable spectral imaging device 100 mounted on the user terminal 200 having the photographing function ( Step S702).

Next, the drive motor 140 may be driven to switch the optical filter 114 to take a spectral image for the next-sized wavelength band (step S703). For example, the driving motor 140 is driven to rotate the filter wheel 119 so that the optical filter 114 corresponding to the next-sized wavelength band is located on a straight line with the light source 220 of the user terminal 200 .

Next, it is determined whether all the optical filters 114 have been photographed (step S704). If not all of the optical filters 114 have been photographed, the process returns to step S702 to repeat steps S702 to S703 for all optical It can be repeatedly performed until the photographing of the filter 114 is completed.

In this manner, the optical filters 114 of the plurality of optical filters 114 are arranged in a line with the light sources 220 of the user terminal 200, based on the photographing speed of the photographing section 210, by steps S702 to S704, By continuously rotating the filter wheel 119 so that the optical filter 114 is positioned, the photographing can be completed for all the bands by switching the optical filter 114. For example, since the spectral image is composed of a plurality of wavelength-wise images, the filter wheel 119 is continuously rotated in accordance with the continuous photographing speed of the photographing unit 210 such as a camera, .

Next, a spectral spectrum may be generated for each of the plurality of stored images 600 according to the plurality of optical filters 114 (step S705). For example, as shown in FIG. 6, a pixel value at a position set for analysis may be expressed for each wavelength corresponding to a plurality of optical filters 114, and a spectral spectrum representing a reference value previously stored for each wavelength may be generated.

More specifically, it is possible to set a position to be analyzed among images stored through the user terminal 200. For example, in FIG. 4, a position corresponding to the skin disease 310 generated in the skin 300 can be set.

Then, pixel values for each of the stored images obtained for different wavelength ranges can be extracted for the set position.

Next, a reference value corresponding to the position can be extracted for comparison with the extracted pixel value. Here, the reference value can correspond to normal skin.

Then, the extracted pixel value and the reference value can be classified into wavelengths corresponding to the plurality of optical filters 114, that is, wavelengths of the spectral image, thereby generating the spectral spectrum. Such spectral spectra can predict and diagnose various skin diseases including skin cancer, atopy, tingling, and dermatitis which may occur in the skin. At this time, alternatively, based on the spectroscopic spectrum generated, the diseased skin and the normal skin can be compared to predict and diagnose the disease.

Next, the generated spectroscopic spectrum can be outputted (step S706). For example, it is possible to output a spectroscopic spectrum which is obtained by comparing a photographed image with a corresponding reference value so that the user can check the state of photographed skin. At this time, alternatively, in the case of predicting diagnosis of a disease in the photographed skin, the result can be outputted together with the spectroscopic spectrum.

Next, when the treatment is required for the outputted spectral spectrum, a light source corresponding to a wavelength for treating the skin at the analyzed position may be irradiated to the treatment target skin (step S707). For example, the skin care light source 150 included in the portable spectral imaging device 100 can be irradiated to the skin to be treated. Alternatively, the light source 220 of the user terminal 200 may be placed on the to-be-treated skin using an optical filter 114 corresponding to a wavelength for treatment, for example, a 630 nm band among the plurality of optical filters 114 You can investigate.

According to this method, an embodiment of the present invention can easily diagnose a skin disease and manage skin at all times easily in a general home using a user terminal such as a smart phone or a tablet, It can be applied to continuous skin management mentoring system by strengthening search function by database of various information such as management after treatment, kinds of skin related diseases, beauty method for current skin condition, and the like, and is increasing due to environmental or genetic factors The skin disease can be diagnosed early, and the social and economic cost due to the skin disease can be alleviated.

Such methods may be implemented by a user terminal 200 as shown in FIG. 1, and in particular as a software program that performs these steps, in which case these programs may be stored on a computer- Or by a computer data signal coupled with a carrier wave in a transmission medium or a communication network.

At this time, the computer-readable recording medium includes all kinds of recording devices in which data that can be read by a computer system is stored. For example, a ROM, a RAM, a CD-ROM, a DVD- , A floppy disk, a hard disk, an optical data storage device, or the like.
