Description

Technical Field

[0001] This invention relates to a smart mirror, its control method, and a cosmetics purchasing system. Background Technology

[0002] Recently, with the increasing attention people pay to beauty, there is a growing demand for accurate skin condition measurement and cosmetics suitable for one's own skin condition. In addition, when applying makeup (e.g., color makeup), there is also an increasing need to confirm the accurate color rendering.

[0003] When performing skin diagnostics, if images are captured and analyzed via camera, the intensity and color temperature of the light significantly impact the diagnostic results. Furthermore, when confirming the color rendering of makeup, the color rendering as seen in a mirror may differ depending on the intensity and color temperature of the light. As mentioned above, lighting conditions have a significant impact on both skin diagnostics and confirming the color rendering of makeup.

[0004] Previously, manually adjusting lighting (light intensity and color temperature) was inconvenient during skin diagnosis and makeup application. Furthermore, manually adjusting lighting could not provide the optimal lighting conditions (light intensity and color temperature) for skin diagnosis and makeup application.

[0005] In addition, there has been a problem that it is difficult to adjust the lighting conditions applied to the user's face to a certain extent due to changes in the external environment where the mirror is located or the user's conditions (e.g., the shadow cast by the user's arm movements).

[0055] The specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings. At the same time, in describing the present invention, detailed descriptions of relevant well-known structures or functions are omitted where it is determined that such detailed descriptions would obscure the essence of the invention.

Figure 6 It shows that it can be controlled Figure 1 A block diagram of the control unit 40 of the terminal unit 10 and the lighting unit 20 of the smart mirror 1. Figure 7 It is shown in Figure 1 An example of the screen displayed on the display 14 of the terminal unit 10. Figure 8 It is shown in Figure 1 The diagram shows another example of the screen displayed on the display 14 of the terminal unit 10.

[0057] refer to Figures 1 to 8 According to an embodiment of the present invention, a smart mirror 1 may include: a terminal 10, including a sensor 12 capable of recognizing a user; an illumination 20, including an LED 22 capable of illuminating the user; and a control 40 capable of controlling at least one of the light intensity and color temperature of the light illuminating the user by the illumination 20, so that the user's body parts can display a preset range of light intensity and color temperature according to the light illuminating the user by the illumination 20.

[0058] The smart mirror 1 of this embodiment can provide the user's skin (e.g., face) with optimized illumination (light intensity and color temperature) required for skin diagnosis and resistant to external changes. For example, the smart mirror 1 can determine the relative position and angle of the illumination unit 20 and the user's body part (e.g., face), and adjust the light intensity and color temperature of the light emitted by the LED 22 of the illumination unit 20 so that the user's body part (e.g., face) displays a certain range of light intensity and color temperature optimized for skin diagnosis.

[0059] The range of light intensity optimized for skin diagnosis can be from 500 Lux to 3000 Lux, and the range of color temperature optimized for skin diagnosis can be from 5000 K to 6800 K. The range of light intensity and color temperature optimized for skin diagnosis can be understood as the light intensity and color temperature displayed on the skin by the light irradiated by the illumination unit 20.

[0060] As described above, the illumination unit 20 can provide the optimized illumination (light intensity and color temperature) required for skin diagnosis and is resistant to external changes, thus enabling accurate skin measurements.

[0061] Skin measurement can be performed by using a camera provided by the terminal 10 to capture images of the user's skin and analyze the captured skin images, or it can be performed using a separate skin measurement device.

[0062] In addition, the smart mirror 1 can automatically provide the optimal lighting (light intensity and color temperature) required for makeup application, adaptable to certain external conditions. For example, the smart mirror 1 can determine the relative position of the lighting unit 20 and the user's body parts (e.g., face) and the relative angle between the lighting unit 20 and the user's body parts (e.g., face), and adjust the light intensity and color temperature of the light emitted by the LED 22 of the lighting unit 20 so that the user's body parts (e.g., face) can display the optimal light intensity and color temperature required for makeup color application, adaptable to a certain range of external conditions.

[0063] In this case, the user's body parts reflected in mirror 30 can display a certain amount of light and color temperature, so the user can confirm the accurate color rendering of the makeup.

[0064] The range of light intensity for confirming optimal color rendering can be from 300 Lux to 3000 Lux, and the range of color temperature for confirming optimal color rendering can be from 2000 K to 8000 K. Here, the light intensity and color temperature for confirming optimal color rendering under certain conditions can be understood as the light intensity and color temperature displayed on the skin by the light irradiated by the illumination unit 20.

[0065] At least one of the terminal unit 10 and the lighting unit 20 may be angle-adjustable. For example, the terminal unit 10 and the lighting unit 20 may each be angle-adjustable to the main body 50, or only the lighting unit 20 may be angle-adjustable to the main body 50, or only the terminal unit 10 may be angle-adjustable to the main body 50.

[0066] In this embodiment, we will describe a scenario where both the terminal unit 10 and the illumination unit 20 can be adjusted at their angles independently.

[0067] Specifically, the terminal unit 10 can be provided with an adjustable angle so that the sensor 12 of the terminal unit 10 can identify the user's body parts (e.g., face).

[0068] Additionally, the lighting unit 20 can be angled to allow the user to see their body parts (e.g., face) through the mirror 30, or to allow light from the LED 22 to illuminate their body parts (e.g., face).

[0069] The angle adjustment of the terminal unit 10 and the illumination unit 20 can be controlled by the angle control unit 41 of the control unit 40, which will be described later. For example, the user's face can be identified by the sensor 12 of the terminal unit 10, and the angle control unit 41 can adjust the angle of the illumination unit 20 so that the user can see their face through the mirror 30. In addition, when the user moves, the user's face can be identified in real time by the sensor 12 of the terminal unit 10, and the angle control unit 41 can adjust the angle of the illumination unit 20 in real time. However, the concept of the present invention is not limited to this, and may include cases where the user manually adjusts the angle of the terminal unit 10 and the illumination unit 20.

[0070] The terminal unit 10 and the lighting unit 20 can be connected via the main body 50. However, the concept of the present invention is not limited to this, and may include cases where the terminal unit 10 and the lighting unit 20 are provided independently of each other without being connected via the main body 50.

[0071] The terminal unit 10 can be selectively combined with the main body 50 and can be provided to be adjustable at an angle (θ1) relative to the main body 50. For example, the terminal unit 10 can be a smartphone or tablet device including a camera, which can be understood as the sensor 12 in this embodiment.

[0072] The terminal unit 10 may include: a sensor 12 that can identify the user; and a display 14 that can receive information from the user or transmit information to the user.

[0073] Sensor 12 can be one of a camera that can capture images of the user's skin, a distance sensor, or a motion sensor.

[0074] When sensor 12 is provided by a camera, it can capture images of the user's skin and perform skin diagnosis based on the captured images. In this case, the skin diagnosis can be performed by the control unit 40 according to a preset algorithm.

[0075] When performing skin diagnosis, if analyzing skin images captured by a camera, the intensity and color temperature of the light emitted during the capture significantly impact the accuracy of the diagnosis. In this embodiment, for accurate skin diagnosis, the illumination unit 20 can provide optimized light intensity and color temperature that are adaptable to varying external conditions.

[0076] Specifically, the amount and color temperature of the light emitted by the LED 22 of the illumination unit 20 can be adjusted to optimize the display of the skin image captured by the camera and to accommodate changes in the amount and color temperature of light under certain external conditions. The amount and color temperature of light displayed in the skin image captured by the camera can be understood as being the same as the amount and color temperature of light displayed on the photographed skin.

[0077] The amount of light and color temperature displayed on the skin can vary depending on the distance between the user and the lighting unit 20 and / or the angle between the lighting unit 20 and the user.

[0078] Therefore, in order to make the skin display the best light intensity and color temperature, the light intensity and color temperature irradiated by the LED 22 of the lighting unit 20 can be varied according to the distance between the user and the lighting unit 20 and / or the angle between the lighting unit 20 and the user.

[0079] The optimal light intensity range for skin diagnosis is 500 Lux to 3000 Lux, preferably 500 Lux to 2000 Lux, and even more preferably 500 Lux to 1500 Lux. Furthermore, the optimal color temperature range for skin diagnosis is 5000 K to 6800 K, preferably 5200 K to 6800 K, and even more preferably 5300 K to 6700 K.

[0080] The range of light intensity for optimal color rendering can be from 300 Lux to 3000 Lux, preferably from 300 Lux to 2000 Lux, and even more preferably from 300 Lux to 1800 Lux. Furthermore, the range of color temperature for optimal color rendering can be from 2000 K to 8000 K, preferably from 4000 K to 7000 K, and even more preferably from 4600 K to 7000 K.

[0081] Additionally, a display 14 can be provided in front of the terminal unit 10, through which information can be received from or transmitted to the user.

[0082] You can select one of the skin diagnosis mode, makeup mode, or selection mode (described later) via the display 14.

[0083] When the selection mode is selected, the user can adjust the amount and color temperature of the light emitted by the lighting unit 20 through the display 14.

[0084] Additionally, the amount and color temperature of the light emitted by the illumination unit 20 can be displayed on the display 14 of the terminal unit 10.

[0085] Figure 7 An example of a display screen 14 showing information about the lighting unit 20 is shown.

[0086] refer to Figure 7 The display 14 may provide: a color temperature adjustment unit 142, which can input the color temperature of the light irradiated by the illumination unit 20; a light intensity adjustment unit 144, which can input the light intensity of the light irradiated by the illumination unit 20; a power display unit 146, which can display whether the smart mirror 1 is working; and a light intensity and color temperature display unit 148, which displays the light intensity and color temperature of the light irradiated by the illumination unit 20 (see reference). Figure 7 ).

[0087] In this embodiment, when the selection mode is selected, the light intensity and color temperature can be adjusted via the terminal unit 10. However, the present invention is not limited to this; when the selection mode is selected, the light intensity and color temperature of the light irradiated by the illumination unit 20 can be adjusted via the illumination adjustment unit 58 provided in the main body 50.

[0088] In addition, when the skin diagnosis mode is selected, skin diagnosis can be performed using skin images captured by the sensor 12 of the terminal unit 10, and the skin diagnosis results can be displayed on the display 14.

[0089] Figure 8 An example of a display screen 14 showing the results of a user's skin diagnosis is shown.

[0090] refer to Figure 8 The display 14 may include: a skin condition display unit 141, which can display the skin condition after analyzing the skin image; and a skin condition process unit 143, which can display the skin condition over time.

[0091] The skin condition display unit 141 can display pigmentation, wrinkles, pores, erythema, etc.

[0092] The skin condition process section 143 can display the skin condition over time after multiple skin condition diagnoses. At this time, the skin condition can be displayed numerically.

[0093] Additionally, the display 14 on the terminal 10 can display recommended cosmetics based on skin condition, and touching the recommended cosmetics can connect to a shopping website. This will be explained in detail later.

[0094] In addition, the smart mirror 1 of this embodiment may include a main body 50 that can support the terminal part 10 and the lighting part 20.

[0095] Specifically, the main body 50 may include: a lower main body 52, which is provided with a connecting part 51 that can support the terminal part 10; and an upper main body 54 that extends upward from the lower main body 52 and can support the lighting part 20.

[0096] Additionally, a control unit 40 may be provided inside the main body 50, which can control at least one of the illumination unit 20, the terminal unit 10, and the angle of the illumination unit 20. The control unit 40 will be described later.

[0097] The lower body 52 has a flat surface that can be placed on the outer bottom surface.

[0098] In addition, the lower main body 52 can be made heavier than the sum of the weights of the terminal part 10, the lighting part 20 and the mirror 30, so that the smart mirror 1 can stand stably.

[0099] A connecting portion 51 that can support the terminal portion 10 can be provided on one side of the lower body 52. ​​For example, the connecting portion 51 can be provided as a groove into which the terminal portion 10 can be inserted.

[0100] A connection terminal (not shown) that can be wired to the terminal 10 can be provided at the joint 51.

[0101] In this case, when the terminal unit 10 is combined with the connecting part 51, the main body 50 and the terminal unit 10 can communicate or charge the terminal unit 10 through the connecting terminal. However, the concept of the present invention is not limited to this, and the main body 50 and the terminal unit 10 can also communicate wirelessly.

[0102] Additionally, the relative angle between the terminal portion 10 and the lower body 52 can be adjusted via a connecting portion 51 provided in the lower body 52. ​​The angle between the terminal portion 10 and the lower body 52 can be understood as a first angle θ1.

[0103] For example, a rotating member 512 that can rotate the terminal portion 10 can be provided on one side of the joint portion 51.

[0104] In this case, the terminal part 10 is combined with the rotating member 512, so that the angle θ1 of the terminal part 10 can be adjusted as the rotating member 512 rotates. The center of the rotating member 512 can be understood as the terminal shaft M1.

[0105] Furthermore, during the insertion of the terminal portion 10 into the connecting portion 51, the rotating member 512 can enter the lower body 52, and after the terminal portion 10 is placed in the connecting portion 51, the rotating member 512 exits from the outside of the lower body 52. ​​Through the process described above, the terminal portion 10 and the rotating member 512 can be combined.

[0106] Additionally, a rear wall 514 supporting the rear side of the terminal portion 10 can be provided at the joint 51.

[0107] The rear wall 514 can be moved to correspond to the angle adjustment of the terminal part 10. For example, the rear wall 514 can support the rear side of the terminal part 10 and move in accordance with the rotation angle of the terminal part 10.

[0108] In this embodiment, the connecting portion 51 is described as having a groove shape into which the terminal portion 10 can be inserted; however, the concept of the present invention is not limited thereto. For example, the connecting portion 51 may also be provided as a bracket that can support the terminal portion 10 or as a gripping device that can hold and fix the terminal portion 10.

[0109] The upper body 54 can be provided in the form of a rod extending upward from the lower body 52.

[0110] An illumination unit support 542 that allows the illumination unit 20 to move can be provided on the upper side of the upper body 54.

[0111] A universal joint that allows the lighting unit 20 to be adjusted in angle, rotated, and moved up and down can be provided inside the lighting unit support 542.

[0112] The lighting unit 20 can be provided to be able to be angle-adjusted, rotated, or moved up and down relative to the upper body 54. Angle adjustment can be understood as movement around the lighting unit's pivot M2, rotation can be understood as movement around the Z-axis, and up and down movement can be understood as movement parallel to the Z-axis.

[0113] In this embodiment, the angle between the upper main body 54 and the lighting part 20 can be understood as the second angle θ2.

[0114] The lighting unit 20 may include a plurality of LEDs 22 capable of emitting light.

[0115] The multiple LEDs 22 provided in the lighting section 20 can be configured along the edge of the mirror 30.

[0116] As described above, when the LED22 is arranged along the edge of the mirror 30, it can evenly illuminate the user's body parts (e.g., face).

[0117] The lighting unit 20 can operate to allow the light emitted by the LED 22 to display different light amounts and color temperatures. For example, the lighting unit 20 can operate in one of the following modes: skin diagnosis mode, makeup mode, and selection mode.

[0118] When operating in skin diagnostic mode, it can illuminate the user's skin with light intensity ranging from 500 Lux to 3000 Lux and color temperature ranging from 5000 K to 6800 K.

[0119] When working in makeup mode, it can irradiate the user's skin with light intensity of 300 Lux to 3000 Lux and color temperature of 2000 K to 8000 K.

[0120] When operating in selection mode, it can emit light with a light intensity and color temperature set by the user.

[0121] The lighting section 20 can be divided into multiple areas including LED 22 (see reference). Figure 4 ).

[0122] Among the LEDs 22 configured in multiple regions A, B, C, D, E, F, G, H, I, J, K, L, LEDs 22 configured in at least two regions can illuminate each other and display light with different light intensity and color temperature.

[0123] Thus, as shadows S are cast on the user's body parts (e.g., face), light of different amounts and color temperatures can be projected onto each other (see reference). Figure 5 ).

[0124] For example, when a user moves their arm while applying makeup, a shadow S may be generated on the user's face. The smart mirror 1 in this embodiment can recognize the shadow S and control the lighting unit 20.

[0125] Furthermore, the shadow cast on a user's body part (e.g., face) will vary depending on which part of the user's body is illuminated by external light. The smart mirror 1 of this embodiment can identify these shadows and control the lighting unit 20 accordingly. This will be explained in detail later.

[0126] In addition, multiple LEDs 22 can emit light according to the user's position and the angle of the lighting unit 20, displaying different light amounts and color temperatures to each other.

[0127] For example, if the user is far from the lighting unit 20, the amount of light illuminating the user may be less. In this case, the farther the user is from the lighting unit 20, the stronger the light emitted by the LED 22 of the lighting unit 20 can be.

[0128] Furthermore, when the angle between the user and the lighting unit 20 increases, the amount of light illuminating the user may decrease. In this case, the larger the angle between the user and the lighting unit 20, the stronger the light emitted by the LED 22 of the lighting unit 20.

[0129] As described above, the light emission of the LED 22 in the lighting unit 20 can be controlled by the control unit 40, which will be described in detail later.

[0130] A mirror 30 can be provided inside the lighting unit 20. The user can see their own body parts (e.g., face) through the mirror 30 and can apply makeup while looking in the mirror 30.

[0131] Alternatively, the mirror 30 can also be provided by a display panel, which can receive and display photos, videos, etc. reproduced by the terminal unit 10.

[0132] The control unit 40 can control the light emitted by the multiple LEDs 22 of the lighting unit 20.

[0133] Depending on the distance between the user and the lighting unit 20 and the relative angle θ3 between the user and the lighting unit 20, the color temperature and light intensity of the light irradiated onto the user's body parts (e.g., face) can be reduced.

[0134] The control unit 40 can calculate the distance between the user and the lighting unit 20, as well as the relative angle θ3 between the user and the lighting unit 20, thereby controlling the amount and color temperature of the light emitted by the LED 22 of the lighting unit 20. As described above, through the control of the control unit 40, the light emitted by the lighting unit 20 can be optimized to display the amount and color temperature required for skin diagnosis mode and makeup mode, and is subject to certain external changes.

[0135] Specifically, the control unit 40 includes: a relative position calculation unit 42, which calculates the relative position of the user and the lighting unit 20; a relative angle calculation unit 44, which calculates the relative angle between the user and the lighting unit 20; a light quantity control unit 46, which controls the light quantity emitted by the lighting unit 20 based on the relative position and the relative angle between the user and the lighting unit 20; and a color temperature control unit 48, which controls the color temperature of the light emitted by the lighting unit 20 based on the relative position and the relative angle between the user and the lighting unit 20.

[0136] The relative position calculation unit 42 can calculate the relative position between the user and the terminal unit 10, and can calculate the relative position between the lighting unit 20 and the terminal unit 10. It can also calculate the distance between the user and the lighting unit 20 from the relative positions between the user and the terminal unit 10 and the relative positions between the lighting unit 20 and the terminal unit 10.

[0137] The relative angle calculation unit 44 can calculate the relative angle θ3 between the user and the lighting unit 20 from the relative position between the user and the lighting unit 20 and the illumination angle of the light irradiated by the LED 22 of the lighting unit 20.

[0138] The specific process described above, in which the control unit 40 controls the amount and color temperature of light emitted by the lighting unit 20 based on the distance between the user and the lighting unit 20 and the relative angle θ3 between the user and the lighting unit 20, will be explained later.

[0139] In addition, taking into account the shadow S covering the user's skin, the control unit 40 can control the light irradiated by the lighting unit 20.

[0140] Specifically, the lighting unit 20 can be divided into multiple regions A, B, C, D, E, F, G, H, I, J, K, and L. At this time, the control unit 40 can control the light emitted by LEDs 22 arranged in two or more regions to exhibit different light intensity and color temperature.

[0141] The control can be understood as being performed by the lighting area control unit 49 of the control unit 40.

[0142] Additionally, the control unit 40 may include an angle control unit 41 that controls at least one angle of the terminal unit 10 and the lighting unit 20.

[0143] For example, the sensor 12 of the terminal unit 10 can identify the user's face, and the control unit 40 can control the angle of the lighting unit 20 so that the lighting unit 20 and the user's face are at a preset angle.

[0144] It can be understood that the angle adjustment of the terminal unit 10 and the lighting unit 20 is controlled by the angle control unit 41.

[0145] Figure 9 This is a sequence diagram of a control method for a smart mirror according to an embodiment of the present invention. Figure 10 It demonstrates mastery Figure 9 A conceptual diagram of step S2, which involves the distance between the user and the lighting unit. Figure 11 It demonstrates mastery Figure 9 A conceptual diagram of step S3, showing the relative angle between the user and the lighting unit. Figure 12 This is a conceptual diagram illustrating the differences in light emitted by the lighting unit 20 based on the relative positions of the user and the lighting unit 20, and the relative angles between the user and the lighting unit.

[0146] refer to Figures 9 to 12 The control method of the aforementioned smart mirror 1 will be explained in detail below.

[0147] According to an embodiment of the present invention, a control method for a smart mirror can be provided, comprising: step S1 of receiving one of a plurality of modes; step S2 of determining the distance between the user and the illumination unit via a control unit 40; step S3 of determining the relative angle between the user and the illumination unit via the control unit 40; step S4 of calculating the light intensity and color temperature of the light emitted by the illumination unit based on the distance between the user and the illumination unit and the relative angle between the user and the illumination unit, so that the user's skin displays a light intensity and color temperature within the range of the input mode; and step S5 of emitting LEDs in the illumination unit to display the calculated light intensity and color temperature. The control of steps S2, S3, S4, and S5 can be performed by the control unit 40.

[0148] Depending on the distance between the user and the lighting unit 20 and the relative angle θ3 between the user and the lighting unit 20, the color temperature and light intensity of the light irradiated onto the user's body parts (e.g., face) can be reduced.

[0149] In this embodiment, the light irradiated by the lighting unit 20 can be adjusted according to the distance between the user and the lighting unit 20 and the relative angle θ3 between the user and the lighting unit 20. Therefore, in the skin diagnosis mode and makeup mode, the optimal light intensity and color temperature can be provided to the user's body parts (e.g., face).

[0150] First, the specific steps of receiving one of the multiple modes, S1, are as follows.

[0151] Multiple modes can include skin diagnosis mode, makeup mode, and selection mode.

[0152] Users can input one of the skin diagnosis mode, makeup mode, or selection mode through the terminal 10, and the input skin diagnosis mode, makeup mode, or selection mode can be transmitted to the control unit 40.

[0153] When the skin diagnosis mode is selected, the illumination unit 20 can illuminate the display with light of optimal intensity and color temperature for skin diagnosis under certain conditions.

[0154] As described above, the light intensity optimized for skin diagnosis under certain conditions can be from 500 Lux to 3000 Lux, and the color temperature optimized for skin diagnosis under certain conditions can be from 5000 K to 6800 K. Here, the light intensity and color temperature optimized for skin diagnosis under certain conditions can be understood as the light intensity and color temperature displayed on the skin by the light irradiated by the illumination unit 20.

[0155] Alternatively, when selecting the skin diagnosis mode, the sensor 12 provided on the terminal 10 can capture images of the skin, and skin diagnosis can be performed based on the captured skin images. At this time, light is shone onto the skin by the illumination unit 20, so that the captured skin images can display optimized light intensity and color temperature under certain conditions.

[0156] When selecting the makeup mode, the amount and color temperature of light used to confirm the optimal color rendering can be displayed by illuminating the screen with the lighting unit 20.

[0157] As described above, the optimal light intensity for color rendering is 300 Lux to 3000 Lux, and the optimal color temperature for color rendering is 2000K to 8000K. Similarly, the optimal light intensity and color temperature for color rendering can be understood as the light intensity and color temperature displayed on the skin by the light irradiated by the illumination unit 20.

[0158] When selecting the selection mode, the light unit 20 can illuminate the display with the light intensity and color temperature set by the user.

[0159] The adjustment of light intensity and color temperature can be accomplished by the display 14 on the terminal 10 or the lighting adjustment unit 58 provided on the main body 50.

[0160] Specifically, when a user inputs the desired light intensity and color temperature to the display 14 of the terminal unit 10, the light displayed by the illumination unit 20 can be illuminated.

[0161] In addition, the user can adjust the lighting adjustment unit 58 provided on the main body 50 to illuminate the display with the light amount and color temperature desired by the user.

[0162] When using the selection mode, it has the advantage of being able to use the smart mirror 1 for things like going to bed.

[0163] Next, the step S2, which involves the control unit 40 measuring the distance between the user and the lighting unit, will be explained in detail (see reference). Figure 10 ).

[0164] Step S2, which determines the distance between the user and the lighting unit, may include: step S21, which calculates the relative position between the user and the terminal unit 10 by the control unit 40; step S22, which calculates the relative position between the lighting unit 20 and the terminal unit 10 by the control unit 40; and step S23, which calculates the distance between the user and the lighting unit 20 by the control unit 40 from the relative position between the user and the terminal unit 10 and the relative position between the lighting unit 20 and the terminal unit 10.

[0165] To explain S21 in more detail, it can be that the sensor 12 of the terminal unit 10 identifies the user's body parts (e.g., face), and after the body parts (e.g., face) identified by the sensor 12 are transmitted to the control unit 40, the control unit 40 calculates the relative position between the sensor 12 and the body parts (e.g., face).

[0166] To explain S22 in more detail, the lighting unit 20 and the terminal unit 10 can be connected through the main body 50. When the sensor 12 is located at a certain part of the terminal unit 10, the relative position of the lighting unit 20 and the terminal unit 10 can be set to a certain value.

[0167] Alternatively, the lighting unit 20 and the terminal unit 10 can be provided independently of each other without being connected through the main body 50. In this case, the control unit 40 can receive the position of the lighting unit 20 and the position of the sensor 12 of the terminal unit 10, and calculate the relative position between the lighting unit 20 and the terminal unit 10.

[0168] In addition, when the lighting unit 20 and the terminal unit 10 are connected through the main body 50, the terminal unit 10, which has various sizes, can also be combined with the connecting part 51 of the lower main body 52. ​​In this case, the position of the sensor 12 provided on the terminal unit 10 can be set to different.

[0169] In this case, the control unit 40 can identify the position of the sensor 12, which has a terminal unit 10 of various sizes.

[0170] When identifying the position of sensor 12, control unit 40 can determine the relative position of sensor 12 and illumination unit 20.

[0171] In addition, the smart mirror 1 of this embodiment may include a database (not shown) of 10 types of storage terminals.

[0172] The locations of sensors 12 based on the type of terminal device (e.g., smartphone, tablet, etc.) can be stored in a database (not shown).

[0173] The control unit 40 can identify the terminal unit 10 connected to the main body 50 and obtain the position of the sensor 12 that matches the type of each terminal unit 10 from the database.

[0174] To explain S23 in more detail, the control unit 40 can calculate the distance between the user and the lighting unit 20 from the relative positions of the user and the terminal unit 10 obtained in step S21 and the relative positions of the lighting unit 20 and the terminal unit 10 obtained in step S22.

[0175] Next, the step S3, which involves the control unit 40 determining the relative angle between the user and the lighting unit, will be explained in detail (see reference). Figure 11 ).

[0176] Step S3, which determines the relative angle between the user and the lighting unit, may include: step S31, which calculates the relative position between the user and the terminal unit 10 via the control unit 40; step S32, which calculates the relative position between the lighting unit 20 and the terminal unit 10 via the control unit 40; step S33, which calculates the relative position between the user and the lighting unit 20 via the control unit 40 based on the relative positions between the user and the terminal unit 10 and between the lighting unit 20 and the terminal unit 10; step S34, which receives the angle of light irradiation from the LED 22 of the lighting unit 20; and step S35, which calculates the relative angle θ3 between the user and the lighting unit 20 based on the relative position between the user and the lighting unit 20 and the angle of light irradiation from the LED 22 of the lighting unit 20.

[0177] Steps S31 and S32 are the same as steps S21 and S22 described above, so detailed explanations of them are omitted.

[0178] Next, the step S4 is specifically described, which calculates the light intensity and color temperature of the light emitted by the lighting unit based on the distance between the user and the lighting unit and the relative angle between the user and the lighting unit, so that the user's skin displays a range of light intensity and color temperature that conforms to the input pattern.

[0179] The input mode can be one of the following: skin diagnosis mode, makeup mode, or selection mode.

[0180] In skin diagnostic mode, the illumination unit 20 can emit light to display a light intensity of 500 Lux to 3000 Lux and a color temperature of 5000 K to 6800 K on the user's skin. In this mode, the light intensity and color temperature emitted by the illumination unit 20 can vary depending on the distance between the user and the illumination unit 20 and the relative angle θ3 between them. The values ​​of light intensity and color temperature emitted by the illumination unit 20 can be calculated taking into account the distance between the user and the illumination unit 20 and the relative angle θ3.

[0181] In addition, when in makeup mode, the lighting unit 20 can illuminate the user's skin to make the skin display a light intensity of 300 Lux to 3000 Lux and a color temperature of 2000 K to 8000 K.

[0182] When in selection mode, the amount and color temperature of the light emitted by the lighting unit 20 can vary depending on the user's settings.

[0183] Next, the step S5 of illuminating the LEDs in the lighting section to display the calculated light intensity and color temperature will be explained in detail.

[0184] The control unit 40 can control the light from the LED 22 illuminated by the lighting unit 20 to display the light intensity and color temperature calculated in S4.

[0185] Figure 13 This is a sequence diagram of a control method for an intelligent mirror according to an embodiment of the present invention.

[0186] refer to Figure 13 In this embodiment, the smart mirror 1 can control the light illumination from multiple LEDs 22 to be different based on the shadows generated on the user's body parts (e.g., face).

[0187] This embodiment can be understood as follows: after step S4, which calculates the light intensity and color temperature of the light emitted by the lighting unit based on the distance between the user and the lighting unit and the relative angle between the user and the lighting unit, it further includes: step S421, which identifies the shadow S generated on the user's skin by the sensor 12 of the terminal unit 10; and step S422, which corrects the light intensity and color temperature of the light emitted by the lighting unit 20 by the control unit 40 taking into account the shadow S.

[0188] Specifically, the control method of the smart mirror may include: step S1` receiving one of multiple modes; step S2` determining the distance between the user and the lighting unit via the control unit 40; step S3` determining the relative angle between the user and the lighting unit via the control unit 40; step S4` calculating the light intensity and color temperature of the light emitted by the lighting unit based on the distance between the user and the lighting unit and the relative angle between the user and the lighting unit so that the user's skin displays light intensity and color temperature within the range of the input mode; step S421 identifying the shadow S generated on the user's skin via the sensor 12 of the terminal unit 10; step S422 correcting the calculated light intensity and color temperature via the control unit 40 and taking into account the shadow S; and step S5` illuminating the LED 22 of the lighting unit 20 to display the corrected light intensity and color temperature.

[0189] Steps S1`, S2`, S3`, and S4` are the same as steps S1, S2, S3, and S4 above, so detailed explanations of them are omitted.

[0190] To give a more specific explanation of S421, the shadow S generated on the user's skin can be identified by the sensor 12 of the terminal 10.

[0191] In the skin area captured by sensor 12, relatively dark areas are identified as shadows S.

[0192] To explain S422 in more detail, the lighting unit 20 can be divided into multiple regions A, B, C, D, E, F, G, H, I, J, K, L, and can be adjusted so that LEDs 22 located in more than two regions have different light quantities and color temperatures.

[0193] This embodiment illustrates a case where the lighting unit 20 is divided into 12 regions (A, B, C, D, E, F, G, H, I, J, K, L). However, if the lighting unit 20 is divided into two or more regions, the number of regions is not limited. The regions of the lighting unit 20 can be understood as virtual regions.

[0194] like Figure 5 As shown, when a shadow S is generated on the right side of the user's skin, the control unit 40 can cause the LEDs 22 in the right-side regions A, B, C, D, E, F, G, H, I, J, K, L of the multiple regions A, B, C, D, E, L of the lighting unit 20 to display a brighter light than the light in the left-side regions G, H, I, J, K, L.

[0195] Figure 14 It is a general description including Figure 1The image shows the smart mirror 1 and the cosmetics purchasing system 2.

[0196] According to one embodiment of the present invention, a cosmetic purchasing system 2 can be provided that allows users to purchase customized cosmetics based on skin diagnoses and their results.

[0197] Specifically, the cosmetics purchasing system 2 can provide a smart mirror 1 and a server 3 that can communicate with the smart mirror 1. The smart mirror 1 is provided to diagnose the user's skin. The server 3 includes a cosmetics database that can store cosmetics information that matches the user's skin condition diagnosed by the smart mirror 1. The cosmetics purchasing system 2 can purchase cosmetics that match the user's skin condition through the smart mirror 1.

[0198] The user's skin can be photographed by the sensor 12 of the terminal unit 10, and the skin can be diagnosed based on the photographed images.

[0199] The skin diagnosis results from the smart mirror 1 are transmitted to the server 3, where the cosmetic information in the server 3's cosmetic database is matched with the skin results. The matching cosmetic information is then displayed on the display 14 of the terminal 10. The cosmetic information displayed on the display 14 of the terminal 10 can be provided in various forms, such as QR codes or cosmetic photos. Users can click on recommended cosmetic information to purchase the recommended cosmetics.

[0200] The above description illustrates a smart mirror 1, its control method, and a cosmetic purchasing system incorporating the same according to embodiments of the present invention.
