1, the skin care system 90 according to the embodiment of the present invention includes a part or all of the user terminal device 100 and the skin care device 110, and includes a communication network or a skin care server, etc. may further include.

Here, "including some or all" means that components such as a communication network or a skin care server are omitted so that the skin beauty management system 90 is configured as shown in FIG. 1, or a part of the components constituting the skin care server Or it means that all of them can be configured by being integrated with other components such as the skin care device 110, and it will be described as including all of them to help a sufficient understanding of the invention.

The user terminal device 100 may include a smart phone as shown in FIG. 1 , or may include various devices capable of displaying an image in addition. For example, it may include a wearable device such as a tablet PC or a domestic S company's Galaxy*Gear that performs the Internet by wearing it on the wrist, as well as a desktop computer or a laptop computer. More precisely, the user terminal device 100 according to the embodiment of the present invention may include any device capable of operating in the GIF animation method. Here, GIF animation means continuous display of GIFs, and GIF is a widely used file format for transmitting raster images on the Internet. A maximum of 256 colors can be used. do.

A user who possesses the skin care device 110 may access a mobile website through the user terminal device 100 such as his or her smartphone, and then select a desired cosmetic product. Figure 1 (a) shows this. Based on this, the user terminal device 100 according to the embodiment of the present invention may operate in conjunction with an external device such as a server that provides a mobile or PC-based website service. The external device may refer to the above-mentioned skin care server. Alternatively, an app store for downloading an app to install an application (hereinafter, an app) may be included.

When the user selects a desired cosmetic from among the cosmetics displayed on the screen of the user terminal device 100, a screen as shown in FIG. 1(b) may be displayed. While guiding how to use the skin care device 110 on one side of the screen, a corresponding GIF animation image is displayed on the other side of the screen. An animation display unit 101 for displaying a GIF animation image is located on the other side of the screen. That is, the animation display unit 101 refers to a portion of the display screen of the user terminal device 100 on which a GIF animation image is displayed. A GIF animation image according to an embodiment of the present invention is composed of a black-and-white image, and the black-and-white image contains information. 3 and 4 are diagrams for explaining this. Of course, the GIF animation image composed of black and white images may be generated in various forms according to the type, ingredient, function, etc. of cosmetics and provided to the user terminal device 100 .

The skin care device 110 uses the screen flicker of a smartphone as a communication means, and for this purpose, it recognizes a GIF animation image made of black and white, and automatically sets the absorption promoting frequency optimized according to the ingredients and functional characteristics of cosmetics. . Here, the frequency is an operating frequency for operating the electrode unit of the skin care device 110 . Previously, skin care is performed with an absorption promoting frequency optimized in relation to the cosmetics selected by the user through the user terminal device 100, and information about this is provided in the GIF animation image, and the skin care device 110 provides information about this. Information is recognized through GIF animation images and the optimal absorption accelerating frequency is automatically set. That is, it can be viewed as setting. Accordingly, the skin care device 110 operates the electrode unit according to the set frequency to perform a skin treatment operation such as high frequency RF or EP. Of course, it may be possible to drive not only the electrodes but also the motor.

In FIG. 2, the product of the skin care device 110 of FIG. 1 is illustrated by way of example. The skin care device 110 includes a main body 200 forming an outer edge, a button unit 210 for selecting power, screen communication, and a function, a status output unit 220 displaying the current operating state, and a high frequency An electrode unit 230 such as an electrode for skin treatment such as RF or EP, and furthermore, a screen communication (receiving) unit for performing screen communication through a GIF animation image implemented on the screen of the user terminal device 100 of FIG. 1 ( 240) may be included. Of course, a driving circuit such as a PCB including a chip such as a CPU and a peripheral circuit may be configured in the main body 200 .

As shown in (c) of Figure 1, by pressing and holding the smart boosting button of the main body for 3 seconds, the update standby state. And when the user puts the skin care device 110 on the picture blinking on the screen of the smartphone, that is, the animation display unit 101, the update is completed within 10 seconds. Of course, the update means that the optimal absorption promoting frequency for the selected cosmetic is set. And, when completed, the LED color of the probe, that is, the status output unit 220 located at the electrode portion of the skin care device 110, is synchronized with the color of the frame as shown in FIG. 1(e). Of course, since such an operation may be implemented in various ways, it will not be particularly limited to any one form.

Looking more specifically with reference to FIGS. 3 and 4 , the skin care device 110 may operate in a platform-independent smart phone screen communication method rather than a dedicated app. A technique is used in which white (W) and black (B) images of GIF animation are recognized according to the flickering shape and number. In the GIF animation, for example, two types of images, black and white, are set to play at intervals of 100ms. Of course, various colors may be selected and used. 3 , it can be recognized that the start code starts when two black codes are continuously recognized. In addition, the data code is to identify the data by the number of blinks until the next start code is displayed after the start code is recognized, black and white blink alternately. For example, [start code + black 1 + white 1 + black 2 + white 2 + black 3 + white 3] + [start code + … ] can be formatted. Furthermore, since 3 black and 3 white data codes were input in data decoding and output determination, it is decoded as data code 3, and a total of 20 codes promised according to the skin type and cosmetic functional ingredients at the stage of the skin care device that received it. Make sure that skin care is performed at a frequency that is optimized for type 3 (eg, sensitivity, relapse).

4 shows various forms that can be implemented through a GIF animation image according to an embodiment of the present invention. In other words, the number of cases for setting the optimal frequency varies. There are five cases in which a cosmetic function can be selected for sensitivity. Also, in the case of intellect, there are five. A total of 20 implementations are possible depending on the skin type, and a GIF animation image for this can be pre-generated and used. Therefore, since the image has information on the optimal frequency for each cosmetic, it can be seen that the skin care apparatus 110 automatically sets the corresponding optimal frequency through the recognition of the GIF image.

Of course, after making a GIF image in advance, matching it with cosmetics, and storing it, when accessing the service from the user terminal device 100 or accessing the service through the app, the corresponding GIF image is implemented on the screen and through this, the skin care device ( 110) recognizes the image through a sensor such as an optical sensor or a scanner, and then skin care is performed.

As a result of the above configuration, the embodiment of the present invention is independent of the hardware or operating system of the smart phone, for example, and allows communication only through a mobile website without the need for a dedicated app, so that anyone, regardless of age or gender, can enjoy a skin care service easily and conveniently.

5 is a block diagram illustrating a detailed structure of the skin care device of FIG. 1 .

As shown in FIG. 5 , the skin beauty device 110 according to the embodiment of the present invention has a communication interface unit 500 , a control unit 510 , an automatic update setting unit 520 , and storage in terms of a driving mechanism. part or all of part 530 .

Here, "including some or all" means that some components such as the storage unit 530 are omitted to configure the skin care device 110, or some components such as the automatic update setting unit 520 are included in the control unit ( 510), which means that it can be configured by being integrated with other components, etc., and will be described as including all in order to help a sufficient understanding of the invention.

The communication interface unit 500 performs an operation for recognizing a GIF animation image composed of a black-and-white image implemented on the screen of the user terminal device 100 of FIG. 1 as will be described later. This may be called 'screen communication' according to an embodiment of the present invention. Accordingly, the communication interface unit 500 may include an optical sensor or optical scanner for recognizing corresponding images, and the optical scanner may be a camera. For example, it may be a CCD camera or the like. That is, the recognition operation may be performed by recognizing or scanning a black-and-white image and determining whether the black-and-white image is a black image or a white image based on the result of the scan data. Accordingly, the communication interface unit 500 may transmit the scanned data, that is, the result to the control unit 510 . For example, the photosensor may include a light emitting unit and a light receiving unit, and the emitted light has different reflection characteristics in a black image and a white image. Therefore, a recognition operation may be performed through this.

In addition, the control unit 510 is in charge of overall control operations of the communication interface unit 500 of FIG. 5 , the automatic update setting unit 520 , and the storage unit 530 constituting the skin care device 110 of FIG. 1 . For example, the control unit 510 may temporarily store scan data, etc. provided from the communication interface unit 500 in the storage unit 530 , then retrieve it and provide it to the automatic update setting unit 520 . Of course, such scan data may be processed in a group or bundle unit. Data codes may be included after the arrival of the start code until the next start code is recognized. As mentioned above, starting with the section where the two black images are repeated, until two new black images are reconfirmed, it can be viewed as one data processing unit. Accordingly, the black image and the white image in the corresponding section are expressed, for example, in the form of binary bits, and it is possible to know which cosmetics are selected by interpreting them. For example, black may be expressed as “1”, white may be expressed as “0”, and it may be possible to express as data such as 8 bits or 16 bits.

The automatic update setting unit 520 operates under the control of the control unit 510 , and a program for performing an operation according to an embodiment of the present invention may be loaded therein. In other words, when the data scanned or recognized by the communication interface unit 500 is received through the control unit 510, an operation for analyzing it is performed, and through this, preset optimal frequency data can be selected. . To this end, the automatic update setting unit 520 may use a lookup table (LUT). In other words, the left side of the LUT, that is, the input side, is the recognition result of the GIF animation image, and the right side may be matched with control data related to the optimal absorption accelerating frequency. Accordingly, when the control data of the optimum absorption accelerating frequency corresponding to the current recognition result is output, the control unit 510 performs automatic setting, that is, setting operation based on this.

The preset data may be periodically updated when a user requests a new setting while selecting a new cosmetic product. Therefore, the automatic update setting unit 520 may analyze the scan data of the GIF animation image for the selected cosmetic product when there is a user's request, and automatically set it to frequency data matching the same. Of course, the LUT is exemplified above, but since the operation may be made in various forms, the embodiment of the present invention will not be limited to any one form. In the embodiment of the present invention, it has been exemplified that the control data for the optimum frequency is provided to the skin care device 110 through the website, but it will not be particularly limited thereto.

The storage unit 530 may store various types of data processed under the control of the control unit 510 , for example, LUTs. Accordingly, when there is a request from the automatic update setting unit 520 , the control unit 510 calls out the frequency data according to the request of the automatic update setting unit 520 or receives it from the user terminal device 100 and automatically receives the frequency data according to the request. You will be able to perform a setting operation.

In addition to the above, the communication interface unit 500, the control unit 510, the update automatic setting unit 520, and the storage unit 530 of FIG. 5 may perform various operations, and other details have been sufficiently described above. instead of content.

Meanwhile, as another embodiment of the present invention, the control unit 510 may include a CPU and a memory, and may be formed as a single chip. The CPU includes a control circuit, an arithmetic unit (ALU), an instruction interpreter and a registry, and the memory may include a RAM. The control circuit performs a control operation, the operation unit performs an operation operation of binary bit information, and the instruction interpretation unit converts a high-level language into a machine language and a machine language into a high-level language, including an interpreter or compiler. , the registry may be involved in software data storage. According to the above configuration, for example, at the beginning of the operation of the skin care device 110, a program stored in the automatic update setting unit 520 is copied, loaded into a memory, that is, a RAM, and then executed to increase the data operation processing speed. can be increased quickly.

The generated voltage or current may be provided to the user's skin through the electrode unit 230 of FIG. 2 . The optimal (operating) frequency may be related to how the double pulse electroporation unit 611 and the bipolar DC microcurrent unit 613 are operated.

The controller 620 may control button input, output waveform generation, power management and battery voltage monitoring, photosensor signal measurement, and the like by employing an 8-bit microprocessor ATmega16A (eg, Microchip, USA). Typically, the control unit 620 recognizes the data input through the optical sensor and the signal amplification unit 630 and automatically sets it, and when there is a user's request, the output circuit unit 610 can be operated based on the automatically set data. have.

The optical sensor and signal amplification unit 630, which is a smartphone communication unit, is a decoder device for sensing and amplifying a black-and-white on/off signal transmitted from a GIF animation of a smartphone screen. The decoder device can be viewed as meaning to analyze or interpret a sensed signal. For example, it may be possible to output the analysis result in the form of 1 and 0.

The power control unit 640 boosts the voltage of 0.8 ~ 1.5V of one AA battery of the battery unit 645 to 5V, which is the main power, and blocks power consumption when the power is turned off for low power management.

In addition to the above, the button unit 600, the output circuit unit 610, the (microcomputer) control unit 620, the optical sensor and signal amplification unit 630, the power control unit 640 and the battery unit 645 of FIG. 6 are various The operation can be performed, and other detailed information has been sufficiently described above, so it will be replaced with the contents.

As shown in FIG. 8 , the photosensor receiver 700 uses a phototransistor device having a spectrum in a region that responds to general visible light.

In addition, since the output current of the phototransistor is very small, the amplifier 710 amplifies a current of several nA to mA through the amplifier 710 in order for the microprocessor to recognize the sensing state. Of course, since various devices such as an operational amplifier (OP amp) may be used in addition to the transistor TR, the TR device will not be particularly limited.

The RC filter circuit 720 blocks high-frequency noise with a low-pass RC filter combined with a resistor (R) and a capacitor (C).

The capture module input unit 730 converts a change in brightness into a pulse form whenever a black or white signal is detected. Here, the pulse may be generated in the form of 1s and 0s.

Alternatively, it may include a size such as whether the voltage is strongly output from the electrode unit.

The skin care device 110 may store data in advance at the time of product shipment, and may periodically update the stored data when a type of cosmetics is added. Of course, the update target here means not the frequency data, but all selectable data. In the former case, since the amount of data to be transmitted is somewhat larger than that of the latter, the latter method may be used to increase the operation speed.
