Description

{DRESSING TABLE AND CONTROLLING METHOD THEREOF}

The present invention relates to a dressing table and its control method capable of adjusting lighting colors according to whether a user is wearing or not.

Generally, a dressing table is a furniture for a beauty article widely used for a home or a hair salon for women to make-up or care for hair. The conventional vanity unit is composed of a table for displaying various cosmetics and makeup tools, a drawer installed in a retractable manner on the table, and a front mirror for confirming the user's state by the user in front of the table.

The user who uses the dressing table generally performs the makeup in an environment where the indoor lighting is reflected. However, it is difficult to brighten the user's face with indoor lighting only. For example, if the user sits down with the backlight in the room, shadowing of the user's face may occur.

Therefore, it is necessary to illuminate the face of the user who wishes to make up the face, so as to create a state suitable for the user to make-up.

Hereinafter, a skin analysis method and an apparatus therefor according to the present invention will be described in detail with reference to the drawings.

The suffix "module" and " part "for the components used in the following description are given or mixed in consideration of ease of specification, and do not have their own meaning or role.

1 and 2 are views showing a dressing table 10 according to the present invention. 1, the mirror-type display unit 120 may be exposed to the outside of the dresser 10. Through the mirror-type display unit 120, the user can check the information output from the vanity unit 10 while viewing his or her own image.

The light source 140 may be installed on both sides (or on either side) of the dressing table 10. The light source 140 may be positioned to illuminate the user's face when the user is positioned in front of the dresser 10. As the user's face is illuminated brightly, the user will be able to make-up in a bright state. 1 and 2 illustrate that the light source unit 140 is located on the left and right sides of the dressing table 10.

A case 12 on which an electronic component can be mounted may be located on the rear side of the display unit. Electronic components such as the communication unit 110, the camera 130, the memory 150, and the control unit 170, which will be described later with reference to FIG. 3, may be mounted on the case 12. The camera 130 mounted on the case 12 can take a role of photographing the outside of the display unit. To this end, it is preferable that the surface of both surfaces of the mirror-type display unit 120 that is in contact with the case 12 is in a state capable of transmitting light.

The dressing table 10 may be combined with a cosmetics refrigerator 20 capable of storing cosmetics. A mirror may be attached to the door 190 for opening and closing the refrigerator 20, but this is not necessarily so. The cosmetic refrigerator 20 may include a temperature controller 170 for controlling the temperature of the refrigerating compartment (or the freezing compartment). The temperature control unit 170 can appropriately control the temperature of the refrigerating compartment (or the freezing compartment) to control the cosmetics to be stored at a proper temperature.

The illustrated dressing 10 may be designed for use on a wall. To this end, a groove may be formed on the back of the case 12 for fastening a pin attached to the wall.

With reference to Fig. 3, the dresser 10 shown in Figs. 1 and 2 will be described in more detail.

3 is a block diagram of an electronic part to be mounted on the dressing table 10. 3, the dressing table 10 according to the present invention includes a communication unit 110, a mirror type display unit 120, a camera 130, a light source unit 140, a memory 150, a sensing unit 160, A control unit 180, and a control unit 170. [

The communication unit 110 receives data from the outside or transmits data to the outside. The dressing table 10 can communicate with an external server or an external terminal through the communication unit 110.

(E.g., Bluetooth, Zigbee or NFC (Near Field Communication)), mobile communication technology (e.g., Long Term Evolution (LTE), High Speed Downlink Packet Access (HSDPA) (Wireless Local Area Network), Wi-Fi (Wireless Fidelity), etc.) may be applied, or wired communication technology may be applied.

The mirror-type display unit 120 serves to illuminate the user using reflection of incident light, and displays information. The mirror-type display unit 120 may have a translucent mirror shape in which light transmittance and reflectance are adjusted so that light is transmitted through one side and light is reflected on the other side. The light reflecting surface is exposed to the outside, so that the user can see his / her appearance in the mirror. The surface through which the light passes is provided so as to face the inside of the dressing table 10 so that the camera 130 mounted inside the dressing table 10 can photograph the outside.

In addition, the mirror-type display unit 120 may have a mutual layer structure with the touch sensor or may be integrally formed with the touch sensor so as to be constituted by a touch screen. When the mirror-type display unit 120 is configured as a touch screen, the mirror-type display unit 120 functions as an input device for providing an input interface between users, and can function as an output device for outputting information .

The camera 130 can receive a video signal. The image data collected through the camera 130 may be analyzed and processed with user control commands. In addition, the controller 170 analyzes the video signal input to the camera 130 to determine whether the user is located in front of the dresser 10 and whether the user in the video is a registered user.

The light source unit 140 may emit light. The light source unit 140 may include a light emitting unit capable of emitting light, such as an LED (Light Emmiting Unit), an incandescent lamp, a fluorescent lamp, or the like. The lighting of the light source unit 140 may be controlled by the control unit 170 or may be controlled by a manual input operation of the switch for turning on / off the light source unit 140, for example. The user may be able to make makeup more easily by using the light illuminated from the light source unit 140. [

The light source unit 140 may include a first light source unit 142 emitting a first color and a second light source unit 144 emitting a second color. The first light source unit 142 and the second light source unit 144 are turned on during the makeup of the user and the second light source unit 144 is turned on after the user's makeup is completed. White and light bulbs can emit light of different colors.

The light emitting units constituting the first light source unit 142 and the light emitting units constituting the second light source unit 144 may be arranged alternately and may be arranged alternately in an array constituting the first light source unit 142 and an array constituting the first light source unit 142 144 may be arranged side by side.

For example, FIG. 4 illustrates an example in which the first light source unit 142 and the second light source unit 144 are disposed. As in the example shown in Fig. 4A, the light emitting units constituting the first light source unit 142 and the light emitting units constituting the second light source unit 144 may be arranged alternately one by one, the arrays constituting the first light source section 142 and the arrays constituting the second light source section 144 may be arranged side by side as in the example shown in Fig.

The first light source unit 142 and the second light source unit 144 may be arranged in a manner different from the illustrated example. For example, the light emitting units constituting the first light source unit 142 and the light emitting units constituting the second light source unit 144 may alternately be arranged at a ratio of N: M (N and M are different natural numbers) The first light source unit 142 and the second light source unit 144 may be disposed at different positions. For example, the first light source unit 142 may be disposed on the left side of the dressing table, and the second light source unit 144 may be disposed on the right side of the dressing table.

The memory 150 stores data to support various functions of the vanity 10. The memory 150 may store a plurality of application programs, for example, applications for skin analysis, and various data, which are driven by the dressing table 10. The program and data stored in the memory 150 can be operated by the control unit 170. [ In addition, information on a user who wants to use the dressing table 10 may be pre-registered in the memory 150.

The sensing unit 160 may detect a user approaching the dresser 10. The control unit 170 activates the camera 130 and analyzes the image input through the camera 130 so that a state in which a nearby user wants to use the dresser 10 Can be determined.

The temperature regulating unit 180 serves to regulate the temperature of the cosmetics receiving unit. The temperature controller 180 may adjust the temperature of the refrigerating chamber (or the freezer) under the control of the user or under the control of the controller 170.

The control unit 170 controls the overall operation of the dressing table 10. The control unit 170 may process or process signals, data, information, and the like input or output through the above-described components, or may drive or run an application program stored in the memory 150 to provide or process appropriate information or functions to the user .

Electronic components such as the communication unit 110, the camera 130, the memory 150, the sensing unit 160, and the control unit 170 shown in FIG. 3 may be mounted in the case shown in FIGS. 3 may be mounted on the cosmetic refrigerator 20 shown in Figs. 1 and 2.

Based on the above description, the skin analysis method according to the present invention will be described in detail.

5 is a flowchart of an illumination control method according to an embodiment of the present invention. 5, when proximity of the user to the dressing table 10 is detected through the sensing unit 160 in step S501, the controller 170 activates the camera 130 in step S502, The user can determine whether the user wants to use the dresser 10 (S503). For example, when a face of a person is recognized from a video signal input through the camera 130, the controller 180 may determine that the user intends to use the vanity 10. [ At this time, in order to distinguish the case where the user simply passes the front of the dressing table 10 and the case where the user wants to use the dressing table 10, the controller 170 controls the main elements of the face The mouth, the eyebrows, etc.) are all detected, the user can judge that he wants to use the dresser 10.

In addition, in order to distinguish the case where the user simply passes the front of the dressing table 10 and the case where the user desires to use the dressing table 10, when the size of the face in the image is equal to or larger than a predetermined size, It can be determined that the user intends to use the vanity unit 10.

For example, FIG. 6 illustrates an example in which a user per each input image determines whether or not the user desires to use the vanity unit 10. As in the example shown in Fig. 6 (a), if the user's face is recognized, all the main elements of the face (e.g., both eyes, nose, mouth, etc.) are captured, The controller 170 may determine that the user wants to use the dresser 10.

Alternatively, as in the example shown in FIG. 6 (b), if the face of the user is recognized but some of the main elements of the face are not captured, the control unit 170 determines whether the user uses the dresser 10 It can be judged that the state is not the desired state.

If all of the main elements of the user's face and face are captured and the user's face size is small as in the example shown in FIG. 6 (c), since the user is far away from the vanity 10, It can be determined that the user does not want to use the dresser 10.

Although the camera 130 is illustrated as being activated when the proximity of the user is sensed through the sensing unit 160, the camera 130 is always activated regardless of whether the sensing unit 160 is sensed or not State can be maintained.

If it is determined that the user wants to use the dresser 10 in step S503, the control unit 170 photographs the face of the user through the camera and turns on the first light unit 142 in step S504. By illuminating the face of the user by turning on the first light source unit 142, the user can help confirm the makeup state of the user during makeup. Here, the first light source 142 may be configured to emit light of a daylight color to help the user confirm his makeup state, but the present invention is not limited thereto. The control unit 170 may control the first light source unit 142 to remain on until the user finishes making-up.

The photographed photograph can be used to determine whether or not the user has completed the makeup at a later time. In addition, the control unit 170 may analyze the photographed photograph to control the display unit to output a result of diagnosing the user's skin condition. Specifically, the controller 170 may perform an analysis of at least one of pores, melanin, oil index, moisture index, skin tone, wrinkles, dullness, and trouble, and control the result to be output to the display unit.

7 is a diagram showing an example of the output of the skin analysis result. The control unit 170 can display the result of each evaluation item numerically and display it or display the result of each evaluation item in a schematic form.

For example, as shown in FIG. 7A, the controller 170 displays a polygon 710, which is a vertex of each evaluation item, and sets the score of each evaluation item as a distance from the center point to the vertex , The skin analysis result can be displayed.

As another example, the control unit 170 may represent each evaluation item with one figure (illustrated as a circle 720 in Fig. 7B) as in the example shown in Fig. 7B, By adjusting the size of each figure, the results for each evaluation item can be displayed in a schematic form.

The control unit 170 accumulates the skin analysis results and may display the change in the skin condition of the user as in the example shown in FIG. 7C.

The skin analysis result display method shown in FIG. 7 is merely an example for convenience of explanation, and the present invention is not limited thereto.

If it is determined that the user has finished makeup (S505), the controller 170 turns off the first light source unit 142 and turns on the second light source unit 144 (S506). Here, by turning on the second light source unit 144 and illuminating the face of the user, the face of the user who has made up the face can be made more colorful. Here, the second light source 144 may be configured to emit light of a warm white color to make a user's face look gorgeous, but the present invention is not limited thereto.

In order to determine whether or not the user has finished makeup, the control unit 170 may take a picture of the user's face at regular intervals or whenever a predetermined condition is satisfied. Thereafter, the controller 170 compares the photographed image before the user starts to make up with the photographed image after the user starts to make up the skin. If the skin tone of the user changes over a certain level, the number of wrinkles decreases, It can be determined that the user has completed the makeup.

For example, the controller 170 may determine whether the user has completed the makeup based on the change in the user's skin tone. For this, the control unit 170 converts the photographs taken before the makeup and the photographs taken after the start of makeup into grayscale using the RGB color, and calculates the contrast values (for example, A value close to 0 is recorded, and a value close to 255 is obtained as the white color is closer to white color.), It is possible to judge whether the whitening effect of the user's skin has increased.

If the user's skin is very sunny or if there are many dots such as dots, spots, freckles, etc. on the face, the part before the make-up will be darkened in the grayscale image. However, if the makeup covers dots, spots, freckles, etc., the part after the make-up will be brighter in the grayscale image. Accordingly, the brightness of the post-makeup image may be higher than that of the pre-makeup image. The larger the difference in brightness, the better the make-up is, the better the skin tone is, and the roughness of the skin is much hidden. Accordingly, the control unit 170 can determine that the user has completed the makeup when the skin tone of the user after the makeup is improved by a predetermined ratio (or a predetermined value) compared to the skin tone of the user before the makeup.

As another example, the control unit 170 may determine whether or not the user has completed the makeup based on the change in the number of wrinkles of the user. The wrinkled skin appears to be inwardly bent and visually curved compared to the non-wrinkled skin. In this case, the wrinkled skin on the photo will be darker than the skin that is not. Accordingly, the control unit 170 can recognize the dark part distributed in the form of a line on the photograph as a wrinkle. At this time, if the makeup can remove the depressed portion of the wrinkled skin, the wrinkled skin will appear to be flat and the portion recognized as wrinkles will be reduced. Accordingly, the controller 170 determines whether the area of the area corresponding to the wrinkles in the pre-cosmetic photograph or the number of the wrinkles is equal to or larger than a predetermined ratio (or a predetermined value) It can be determined that the makeup of the user is completed.

As another example, the control unit 170 may determine whether or not the user has completed the makeup based on the change in the number of pores of the user. In the photo, the pore area becomes darker than the surrounding skin. Accordingly, the controller 170 can recognize a dark part distributed in the form of a picture point as a pore. At this time, if the pores can be pegged by make-up, the pores will appear to be flat, and the portion recognized as pores will be reduced. Accordingly, when the number of pores in the pre-undamaged photograph decreases to a predetermined ratio (or a predetermined value) in comparison with the number of the pores in the photographed image after the start of the makeup, the controller 170 can determine that the user's makeup is completed.

In the case of wrinkle analysis, it may be desirable to target the entire area of the face, but this is not necessarily the case for pore analysis. The control unit 170 may determine that the makeup of the user is completed when the pore improvement for a partial area of the face is confirmed.

As described above, the control unit 170 may set at least one analysis region in the face of the photographed user, and then perform skin analysis for each analysis region.

For example, FIG. 8 shows an example in which a plurality of analysis regions are set in the face of a user. The control unit 170 can confirm positions of both eyes, nose, and mouth from the face of the user in the extracted image. Once the locations of the main elements of the enumerated face are identified, the controller 170 may set a plurality of analysis areas on the face based on the locations of the identified key elements. 8, the forehead 810, the balls 820 and 830, the nose 840, and the jaw 850 are set as the analysis regions.

The control unit 170 may determine that the user has completed the makeup if the improvement of the skin tone, the reduction of the wrinkles, or the decrease of the pores is confirmed in all of the analysis regions or at least a part of the analysis regions .

In order to determine whether or not the user has finished makeup, the control unit 170 needs to take a picture of the user's face after the user starts making up the makeup. At this time, the control unit 170 may photograph a picture at predetermined time intervals or may take a picture every time a predetermined condition is satisfied.

For example, while the user is performing makeup, the user's hand will be positioned around the user's face. In consideration of this, the control unit 170 photographs a photograph when the face of the user is covered by the hand and can not be covered by the hand, or photographs when the face of the user is not covered by the hand and the predetermined time has elapsed .

As another example, the controller 180 may determine that the user completes the makeup when the cosmetic is taken out of the cosmetic refrigerator and the drawn cosmetic is again drawn into the cosmetic refrigerator. The camera 130 may be installed in the cosmetics refrigerator to determine whether the cosmetics refrigerator is drawn or not. The control unit analyzes the image input through the cosmetics refrigerator to determine whether the cosmetics are drawn or not.

Thereafter, if it is determined that the user does not want to use the dresser 10 any more (S507), the control unit can turn off the second light source unit 144 (S508). For example, when the user exits the dresser 10 and the user does not return to the dresser 10 for a predetermined time or longer, the controller 170 analyzes the image input through the camera 130, ) Will not be used.

5, the first light source unit 142 and the second light source unit 144 may be automatically turned on / off by the controller 170 or manually turned on / off by the user's input It is possible. For example, if a user input for turning on the second light source unit 144 is received even before the user finishes making-up, the control unit 170 may control the second light source unit 144 to turn on, The control unit 170 may control the first light source unit 142 to turn on when a user input for turning on the first light source unit 142 is received. At this time, the controller 170 may control to maintain either the first light source 142 or the second light source 144 in the ON state, or both the first light source 142 and the second light source 144 to maintain the ON state.

According to one embodiment of the present invention, the above-described method (operation flow diagram) can be implemented as a code that can be read by a processor on a medium on which the program is recorded. Examples of the medium that can be read by the processor include ROM, RAM, CD-ROM, magnetic tape, floppy disk, optical data storage, etc., and may be implemented in the form of a carrier wave (e.g., transmission over the Internet) .
