In addition, the processor  400  may control the care equipment such that the driving set value of the care equipment recommended by the skin condition measurement result is implemented when the care equipment is operated. 
     The device  1  for skin condition measurement and skin care according to the present invention includes a sensor unit  100  for detecting a user located within a predetermined distance. 
     The sensor unit  100  performs a function of determining whether an object is present in front of the device  1  and whether the object is a user (person). 
     As shown in  FIG. 1 , the sensor unit  100  may include a sensor for determining whether an object is present in front of the device  1 , and a sensor for determining whether the object is a user (person). 
     In one embodiment, the sensor unit  100  may include: a first sensor for detecting an object in front of the device  1 ; and a second sensor for determining whether the object is the user. 
     The first sensor may be, for example, an optical sensor. The optical sensor serves to detect the presence or absence of an object in front of the device  1 , and may be located on any part of a front surface of the device  1 . 
     The second sensor may be, for example, an IR temperature sensor. The IR temperature sensor serves to determine whether the object in front of the device is the user, and may be located on any part of a front surface of the device. 
       FIG. 1  shown that the first sensor is located at the top or bottom of the front opening/closing door  500 , and the second sensor is located at the top or bottom of the front opening/closing door  500 . However, this is only an example according to the present invention. Each position of the sensor unit  100  including the first sensor and the second sensor is not limited as shown in  FIG. 1 . 
     In addition, the sensor unit  100  may further include a temperature check sensor for checking a temperature change of the user face in real time. 
     In one embodiment, the sensor unit  100  may further include a third sensor for checking the temperature change of the user face in real time. Through the third sensor, the temperature change of the user face may be checked with an image in real time according to using the care equipment described later, and a person&#39;s body temperature may be remotely measured by checking a temperature particularly on a forehead area. The third sensor may be, for example, an IR sensor, but the present invention is not limited thereto. 
     In addition, the sensor unit  100  may further include a sensor for measuring a body temperature of the user by checking a temperature of a forehead part of the user face. 
     In one embodiment, the sensor unit  100  may further include a fourth sensor capable of measuring a body temperature by checking a temperature of a forehead part of the user in real time. The fourth sensor may be designed to measure, for example, a temperature of a skin surface above the temporal artery, so as to measure the user&#39;s body temperature in real time. 
     Meanwhile, the sensor unit  100  may further include a distance sensor used to detect a location of the user when obtaining the user face image by the user face-photographing camera  300 , or detect the distance between the device  1  and the user for a virtual touch implemented when the front opening/closing door  500  includes the half-mirror glass. 
     The distance sensor may be, for example, an ultrasonic sensor or a Time of Flight (ToF). 
     The distance sensor may be used as an element configured to limit a shift of the user&#39;s location upon photographing the user face image for measuring the user&#39;s skin condition, or implement a virtual touch by sensing a distance between the device  1  and the user. 
     Accordingly, the distance sensor may enable to prevent the face image from being inaccurately obtained due to deviation of the user face, obtain the user face image that is clearer, and effectively implement the virtual touch. 
     When it is determined, through the distance sensor, that the user face is separated from the device  1 , the device according to the present invention may notify the user face deviation by using the display unit  501  of the front opening/closing door  500  or a separate audio unit in the device  1 .

In the above case, the processor  400  may be designed to obtain a three-dimensional modeled face image by using the user face images obtained from the 3D ToF sensor, and may be designed to interpret the user&#39;s motion and drive a corresponding preset mode. 
     The device  1  according to the present invention includes a light source unit  200  including a plurality of light sources. 
     The light source unit  200  includes a plurality of light sources that emit white light or UV light, and may emit light when the user is detected by the sensor unit  100  or emit light upon photographing to obtain the user face image. 
     The light source unit  200 , as shown in  FIG. 1  for example, may be located on both sides of the front opening/closing door  500 , but the present invention is not limited thereto. 
     The type and intensity of the light source included in the light source unit  200  may be different according to each mode of the device  1 . For example, in the standby mode, the brightness may be implemented to enable the user to perform makeup or the like through the display unit  501  located in the front opening/closing door  500 . In the operation mode of obtaining the user face image for skin condition measurement through the user face-photographing camera, the brightness may be improved compared to the standby mode. Meanwhile, in the standby mode, the display unit  501  is required to have an appropriate light transmittance in order for the user to perform makeup or the like through the display unit  501  located in the front opening/closing door  500 . Accordingly, in order to implement the above function, the display unit  501  may include the half-mirror glass. 
     The device  1  according to the present invention includes a user face-photographing camera  300  for photographing a user face image to measure a skin condition of the user. 
     The user face-photographing camera  300  serves to provide data for skin condition measurement of the user by providing an image obtained by photographing the user face at least once to the processor  400 . 
     The user face-photographing camera  300  may be configured, for example, as a single camera, or may be configured as a dual camera or quad camera. When the user face-photographing camera  300  is configured as the dual or quad camera, a polarizing plate having different polarization axes may be included on a front side, or a polarizing film, UV pass filter or the like may be located on the front side. In this case, the device  1  may implement a function of obtaining a polarized image and a UV image according to a change in photographing mode. 
     The device  1  according to the present invention includes a processor  400  designed to provide a skin condition measurement result by analyzing the user face image obtained by the user face-photographing camera  300 , and recommend a type of the care equipment and a driving set value located in the inner space. 
     In particular, the device  1  according to the present invention includes a processor  400  designed to recommend customized care equipment based on the analyzed skin condition measurement result, and recommend a driving set value of the care equipment, in addition to simply providing the skin condition measurement result. Thus, the connection between the skin condition measurement and the skin care is excellent. 
     The processor  400  may control the overall driving and operating of the device in connection with various configurations in the device. 
     The processor  400  analyzes the user face image obtained by the user face-photographing camera  300 . 
     In one embodiment, the processor  400  may analyze a single user face image obtained by the user face-photographing camera  300 , or analyze an entire image of the user face obtained by extracting a specific area of the user face from each of a plurality of user face images obtained based on a plurality of photographing parameters set to extract the specific area of the user face, and combining the extracted specific area of the user face. 
     The term “single user face image” used herein refers to a single image obtained by a camera for skin condition analysis and analyzed by a processor. The above term is used in the present specification to differentiate the term from the entire user face image formed through a technology of extracting and combining a specific area in a plurality of user face images obtained based on a plurality of photographing parameters. 
     The term “entire user face image” used herein refers to a user face image that is formed through a technology of extracting and combining a specific face area from each of a plurality of user face images obtained based on a plurality of photographing parameters, and is used for skin condition measurement. 
     In one embodiment, the processor  400  may analyze a single user face image that is a user face image obtained by photographing a user face based on arbitrary photographing parameters. In the above case, the processor  400  may control the photographing parameters of the user face-photographing camera  300  and the brightness of the light source unit  200 . 
     Specifically, the processor  400  may analyze the brightness of the user face image obtained based on preliminary photographing parameters, and set the preliminary photographing parameters as the photographing parameters. The preliminary photographing parameters may be determined according to an external lighting environment. In the above case, the processor  400  may obtain a user face image based on the photographing parameters set based on the preliminary photographing parameters, and may set the user face image as a single user face image for skin condition measurement. 
     In addition, the processor  400  may extract a specific area of a user face from each of a plurality of user face images obtained by photographing the user face based on a plurality of photographing parameters, and analyze an entire image of the user face obtained by combining the extracted specific area of the user face. 
     Specifically, the processor  400  may form an entire user face image for skin condition measurement by extracting a specific area of the user face from each of a plurality of user face images obtained based on a plurality of photographing parameters set to extract the specific area of the user face, and combining the extracted specific area of the user face, and may set the formed image as an entire user face image for skin condition measurement. 
     The photographing parameters for analyzing the user face skin are set by the processor  400 . The photographing parameters, for example, may be the intensity, type and/or direction of the light source included in the light source unit  200 , or may be a shutter speed and/or an aperture value of the user face-photographing camera  300 . 
     In one embodiment, the photographing parameters may include at least one of the intensity of the light source, the direction of the light source, the shutter speed of the camera, and the aperture value. 
     Hereinafter, operations of the processor  400 , which is designed to form the entire user face image for skin condition measurement by extracting and combining the specific area of the user face based on a plurality of preliminary photographing parameters and then analyze the formed image, will be described in more detail. 
     The processor  400  is designed to analyze the brightness of a plurality of user face images obtained based on a plurality of preliminary photographing parameters, and set at least one of the preliminary photographing parameters as the photographing parameters. 
     In one embodiment, when an image photographed based on a first preliminary photographing parameter among the preliminary photographing parameters has a brightness value in a preset range with respect to a first area (for example, a central area of the face) of the user face, the processor  400  may be designed to set the first preliminary photographing parameter as the first photographing parameter corresponding to the first area of the user face. In addition, when an image photographed based on a second preliminary photographing parameter among the preliminary photographing parameters has a brightness value in a preset range with respect to a second area (for example, a peripheral area of the face) of the user face, the processor may be designed to set the second preliminary photographing parameter as the second photographing parameter corresponding to the second area of the user face. 
     In other words, the processor  400  may be designed to set a first preliminary photographing parameter, which is configured to have a brightness value in a preset range with respect to the first area of the user face image, as the first photographing parameter, and set a second preliminary photographing parameter, which is configured to have a brightness value in a preset range with respect to the second area of the user face image, as the second photographing parameter. 
     Based on the photographing parameters, the processor  400  is designed to extract the specific area of the user face from each of the user face images obtained based on the set photographing parameters. 
     In one embodiment, the processor  400  may be designed to obtain a first user face image by photographing a user face based on the first photographing parameter, and obtain a second user face image by photographing the user face based on the second photographing parameter. In addition, the processor may be designed to extract a user face area corresponding to each of the images from the images, and obtain an entire face image by combining the extracted user face areas. 
     In other words, the processor  400  may be designed to extract a first face area from the first user face image obtained by the first photographing parameter, and extract a second face area from the second user face image obtained by the second photographing parameter. In addition, the processor may be designed to form the entire user face image for skin condition measurement by combining the first face area and the second face area. 
     When the first face area and the second face area are combined, the processor  400  may be designed to perform a brightness correction to combine the first face area and the second face area. 
     Specifically, the processor  400  may be designed to determine a brightness difference value between the first face area and the second face area near a boundary between the first face area and the second face area, and the processor  400  may be designed to determine a combination weight for at least one of the first face area and the second face area based on the brightness difference value. The combination weight may refer to a weight for adjusting the brightness. In addition, the processor may be designed to adjust the brightness of at least one of the first face area and the second face area based on the combination weight, and then combine the areas. 
     Through the configuration of the processor  400  as described above, the entire user face image for more accurate skin condition measurement can be obtained, and based on this, the skin condition can be effectively analyzed. 
     The processor  400  is designed to provide the skin condition measurement result to the user after analyzing the user face image, and recommend a type of the care equipment and a driving set value located in the inner space. 
     The skin condition measurement result of the processor  400 , for example, may include an overview indicating the skin condition for each face part, a skin age, a skin score, a skin trouble, and a score for each skin condition diagnosis factor, but the present invention is not limited thereto. 
     The skin condition measurement of the processor  400 , for example, may be implemented based on skin condition measurement data stored in a memory unit of the device. Regarding the skin condition measurement data stored in the memory unit, because latest skin condition measurement information provided by a big data unit of an external server is updated in real time, an accurate skin condition measurement result may be provided to the user. 
     The processor  400  is designed to recommend a type of the care equipment and a driving set value located in the inner space, together with the skin condition measurement result. 
     At least one care equipment  2  is located in the inner space  600  of the device according to the present invention, and the processor  400  recommends any one of the care equipment  2  located in the inner space  600 , based on the skin condition measurement result. In addition, the processor  400  is designed to recommend the driving set value of the recommended care equipment  2 . 
     In one embodiment, the processor  400  may be designed to provide at least one of the care equipment  2 , which is located in the inner space  600  of the device and improving the skin condition based on the skin condition measurement result, on the display unit  501 , and recommend a driving set value including the using time, using intensity, using mode, and the like of the provided care equipment  2 . 
     Further, the processor  400  included in the device  1  according to the present invention controls the care equipment  2  so that the recommended care equipment  2  may be driven according to the driving set value. 
     In other words, the processor  400  controls the care equipment  2  such that the driving set value of the care equipment recommended by the skin condition measurement result is implemented when the care equipment  2  is operated. 
     The device  1  according to the present invention controls the driving set value during the initial operation of the care equipment  2  to correspond to the skin condition measurement result in addition to simply diagnosing skin conditions and recommending care products, so that the connectivity between skin condition measurement and care process and the skin condition improvement effect can be ensured. 
     The control of the processor  400  for the care equipment  2 , for example, may be performed by a communication module described later. Specifically, the door opening of the front opening/closing door  500  is detected by the door sensor of the device  1  and/or the door opening is detected by a signal strength variation of a Bluetooth Low Energy, and then data on the driving set value is BLE advertised and transmitted to the care device  2  from the device  1 , so that the care equipment  2  may be controlled such that the driving set value of the care equipment  2  set in the processor  400  may be implemented when the care equipment  2  is operated. 
     The processor  400  may control the user interface (UI) provided on the display unit  501  of the front opening/closing door  500  according to the standby mode, the operation mode, the skin condition measurement mode and the skin condition care mode, the intensity and the direction of the light source included in the light source unit  200 , and the shutter speed and the aperture value of the user face-photographing camera  300 . 
     In addition, the processor  400  may recognize a state, in which the user uses the recommended care equipment  2  at a predetermined separation distance or more, as a manual mode, and control an off-operation of the display unit included in the front opening/closing door  500 . 
     In one embodiment, the processor  400  may control the off-operation of the display unit  500  according to switching to the manual mode driven when the recommended care equipment is spaced apart from the device for skin condition measurement and skin care by a predetermined distance or more.
