Description

Technical Field

[0001] The present disclosure relates to a wearable device configured to adjust a light transmittance according to an illuminance of an external light source and a control method thereof. Background Art

[0002] Various services and additional functions provided by electronic devices (e.g., portable electronic devices such as augmented reality (AR) glasses) are gradually increasing. To increase the effective value of these electronic devices and meet the needs of various users, communication service providers or electronic device manufacturers are competitively developing electronic devices to provide various functions and distinguish them from other companies. Accordingly, various functions provided by electronic devices are becoming increasingly complex.

[0003] The above information is presented only as background information to help understand the present disclosure. No determination has been made, and no assertion is made, as to whether any of the above constitutes prior art with respect to the present disclosure. Summary of the Invention

[0004] Technical Problem

[0005] Various devices for adjusting a light transmittance of a lens according to an external illuminance have been provided. The devices according to the related art as described above can adjust the light transmittance of the entire lens only according to the external illuminance, but fail to provide a function of adjusting the light transmittance of a part of the lens based on the position of an external light source. For example, since the devices according to the related art provide only a function of adjusting the light transmittance of the entire lens based on the external illuminance, when the light transmittance of the entire lens is high, information about a part of an image having a low light amount (e.g., a part of an image having a low illuminance) may be provided to a user. However, information about a part of an image having a large amount of light (e.g., a region where the sun is located in a landscape image) may not be provided to the user.

[0006] Aspects of the present disclosure are directed to at least solving the above problems and / or disadvantages and at least providing the advantages described below. Accordingly, one aspect of the present disclosure is to provide a wearable device configured to adjust a light transmittance according to an illuminance of an external light source and a control method thereof.

[0007] Another aspect of the present disclosure is to provide a wearable device in which a light transmittance of a part of at least one lens included in the wearable device is controlled based on the position of an external light source (e.g., a real object) (e.g., controlling the lens such that a light transmittance of a region corresponding to a region having a high illuminance on a captured image is decreased and a light transmittance of a region corresponding to a region having a low illuminance on the captured image is increased) to improve visibility of an external object.

[0008] Another aspect of the present disclosure is to provide a wearable device, wherein the transmittance of a part of at least one lens included in the wearable device is controlled (for example, the lens is controlled such that the transmittance of the area of the lens corresponding to the area with high illuminance on the captured image is reduced, and the transmittance of the area of the lens corresponding to the area with low illuminance on the captured image is increased). Based on the position of an external light source (such as a real object), an effect substantially the same as high dynamic range (HDR) correction is achieved without performing HDR correction, thereby reducing the power consumption of the wearable device.

[0009] Another aspect of the present disclosure is to provide a method for controlling a wearable device, wherein the transmittance of a part of at least one lens included in the wearable device is controlled based on the position of an external light source (such as a real object) (for example, the lens is controlled such that the transmittance of the area of the lens corresponding to the area with high illuminance on the captured image is reduced, and the transmittance of the area of the lens corresponding to the area with low illuminance on the captured image is increased) to improve the visibility of an external object.

[0010] Another aspect of the present disclosure is to provide a method for controlling a wearable device, wherein the transmittance of a part of at least one lens included in the wearable device is controlled based on the position of an external light source (such as a real object) (for example, the lens is controlled such that the transmittance of the area of the lens corresponding to the area with high illuminance on the captured image is reduced, and the transmittance of the area of the lens corresponding to the area with low illuminance on the captured image is increased) to achieve an effect substantially the same as HDR correction without performing HDR correction, thereby reducing the power consumption of the wearable device.

[0011] Other aspects will be set forth in part in the following description, and in part will be obvious from the description, or may be learned by practice of the presented embodiments.

[0012] Technical solution

[0013] According to one aspect of the present disclosure, a wearable device is provided. The wearable device includes at least one camera, at least one lens, and at least one processor, wherein the at least one processor may be configured to identify the illuminance information of an image obtained by the at least one camera, determine a position on the at least one lens corresponding to the illuminance information based on the identified illuminance information, determine the average illuminance of the image based on the illuminance information corresponding to the determined position, compare the illuminance information corresponding to the determined position with the average illuminance, and adjust the transmittance of a part of the at least one lens based on the result of the comparison.

[0014] According to another aspect of the present disclosure, a method for controlling a wearable device is provided. The method includes: identifying illuminance information of an image obtained through at least one camera of the wearable device, determining a position on at least one lens of the wearable device corresponding to the identified illuminance information, determining an average illuminance of the image based on the illuminance information corresponding to the determined position, comparing the illuminance information corresponding to the determined position with the average illuminance, and adjusting a light transmittance of a part of at least one lens based on a result of the comparison.

[0015] Beneficial effects

[0016] Embodiments of the present disclosure may provide a wearable device in which a light transmittance of a part of at least one lens included in the wearable device can be controlled based on a position of an external light source (e.g., a real object) (e.g., controlling the lens such that a light transmittance of an area corresponding to a high-illuminance area on a captured image of the lens decreases and a light transmittance of an area corresponding to a low-illuminance area on the captured image of the lens increases) to improve visibility of an external object.

[0017] Embodiments of the present disclosure may provide a wearable device in which a light transmittance of a part of at least one lens included in the wearable device can be controlled (e.g., controlling the lens such that a light transmittance of an area corresponding to a high-illuminance area on a captured image of the lens decreases and a light transmittance of an area corresponding to a low-illuminance area on a captured image of the lens increases). Based on a position of an external light source (e.g., a real object), an effect substantially the same as high dynamic range (HDR) correction can be achieved without performing high dynamic range (HDR) correction, thereby reducing power consumption of the wearable device.

[0080] According to various embodiments, the camera module 250 may capture a still image and / or a moving image. The camera module 250 may include at least one of a lens, at least one image sensor, an image signal processor, or a flash.

For example, the wearable device 200 includes a plurality of camera modules each having different attributes (e.g., viewing angle) or functions, and may control the viewing angle of the camera module to be changed based on a user's selection and / or trajectory information. For example, at least one of the plurality of camera modules is a wide-angle camera, and at least another one may be a telephoto camera.

[0088] According to various embodiments, a processor (e.g., Figure 1 processor 120) of ) may determine the movement of the wearable device 200 and / or the movement of the user by using information of the wearable device 200 obtained by using at least one of a gesture sensor, a gyro sensor, or an acceleration sensor of a sensor module (e.g., Figure 1 sensor module 176) of ) and the movement of the user obtained by using the first camera module 251 (e.g., the user's body approaching the wearable device 200). According to another embodiment, in addition to the above sensors, the wearable device 200 may further include a magnetic (geomagnetic) sensor capable of measuring an azimuth angle by using a magnetic field and magnetic field lines and / or a Hall sensor capable of obtaining movement information (e.g., a moving direction or a moving distance) by using the intensity of a magnetic field. For example, the processor determines the movement of the wearable device 200 and / or the movement of the user based on information obtained from the magnetic (geomagnetic) sensor and / or the Hall sensor.

[0089] According to various embodiments (not shown), the wearable device 200 may perform an input function (e.g., a touch and / or pressure sensing function) that allows interaction with the user. For example, elements configured to perform a touch and / or pressure sensing function (e.g., a touch sensor and / or a pressure sensor) are provided on at least a part of the wearing member 203. The wearable device 200 may control a virtual image output through the display member 201 based on information obtained through the elements. For example, sensors related to the touch and / or pressure sensing function are configured in various types, including a resistive type, a capacitive type, an electromagnetic (EM) type, or an optical type. According to another embodiment, the elements configured to perform the touch and / or pressure sensing function may be all or partially the same as Figure 1 the elements of the input module 150 of ).

[0090] According to various embodiments, the wearable device 200 may include a reinforcing member 260 disposed in the inner space of the lens frame 202 and having a stiffness higher than that of the lens frame 202.

[0091] According to various embodiments, the wearable device 200 may include a lens structure 270. The lens structure 270 may refract at least a part of light. For example, the lens structure 270 may be a prescription lens having a predetermined refractive power. According to another embodiment, the lens structure 270 may be disposed behind the second window member of the display member 201 (e.g., in the +Y direction). For example, the lens structure 270 is positioned between the display member 201 and the user's eyes. For example, one surface of the lens structure 270 faces the display member.

[0092] According to various embodiments, the housing 210 may include a hinge cover 227 that may hide a portion of the hinge structure 229. Another portion of the hinge structure 229 may be received or hidden between an inner housing 231 and an outer housing 233, which will be described later.

[0093] According to various embodiments, the wearing member 203 may include an inner housing 231 and an outer housing 233. The inner housing 231 may be, for example, a housing configured to face the user's body or directly contact the user's body and may be made of a material having a low thermal conductivity (e.g., synthetic resin). According to another embodiment, the inner housing 231 may include an inner surface facing the user's body (e.g., Figure 2a the inner surface 231c). The outer housing 233 may include, for example, a material capable of at least partially transferring heat (e.g., a metallic material) and may be coupled to face the inner housing 231. According to another embodiment, the outer housing 233 may include an outer surface opposite the inner surface 231c (e.g., Figure 2a the outer surface 231d). In an embodiment, at least one of the circuit board 241 or the speaker module 245 may be received in a space within the wearing member 203 that is separated from the battery 243. In the illustrated embodiment, the inner housing 231 may include a first housing 231a and a second housing 231b, the first housing 231a including the circuit board 241 or the speaker module 245, the second housing 231b being configured to receive the battery 243, and the outer housing 233 may include a third housing 233a and a fourth housing 233b, the third housing 233a being coupled to face the first housing 231a and the fourth housing 233b being coupled to face the second housing 231b. For example, the first housing 231a and the third housing 233a are coupled (hereinafter, referred to as "the first housing portions 231a and 233a") to receive the circuit board 241 and / or the speaker module 245, and the second housing 231b and the fourth housing 233b are coupled (hereinafter, referred to as "the second housing portions 231b and 233b") to receive the battery 243.

[0094] According to various embodiments, the first housing portions 231a and 233a may be rotatably connected to the lens frame 202 by a hinge structure 229, and the second housing portions 231b and 233b may be connected to or mounted on the ends of the first housing portions 231a and 233a by connection members 235. In some embodiments, the portion of the connection member 235 that contacts the user's body may be made of a material having a low thermal conductivity, for example, an elastic material such as silicone, polyurethane, or rubber, and the portion of the connection member 235 that does not contact the user's body may be made of a material having a high thermal conductivity (e.g., a metallic material). For example, when heat is generated from the circuit board 241 or the battery 243, the connection member 235 blocks heat transfer to the portion that contacts the user's body and dissipates or releases the heat through the portion that does not contact the user's body. According to yet another embodiment, the portion of the connection member 235 configured to contact the user's body may be interpreted as a part of the inner housing 231, and the portion of the connection member 235 that does not contact the user's body may be interpreted as a part of the outer housing 233.

[0095] Although only the wearable device 200 is illustrated and described in Figures 2a to 2c , the present disclosure is not limited thereto, and Figures 2a to 2c some components of the wearable device 200 shown in

[0096] Figure 3 may also be included in an electronic device such as a smart phone and a tablet PC.

[0097] Reference Figure 3, in operation 310, a wearable device 200 (e.g., processor 120) according to an embodiment of the present disclosure may identify illuminance information of an image obtained by at least one camera (e.g., second camera module 253). The wearable device 200 according to an embodiment of the present disclosure may identify the illuminance information of the image based on an image histogram of the obtained image. When a separate illuminance sensor is provided, the wearable device 200 according to an embodiment of the present disclosure may also identify the illuminance information of the image by mapping illuminance sensing data obtained from the illuminance sensor (e.g., an average of illuminance sensing values when multiple illuminance sensors are provided) and the image obtained by at least one camera (e.g., second camera module 253) to each other.

[0098] Figure 4 Illustrates functions or operations of a wearable device that identifies illuminance information in an image acquired by at least one camera (e.g., second camera module 253) included in the wearable device according to an embodiment of the present disclosure.

[0099] Reference Figure 4 , the wearable device 200 according to an embodiment of the present disclosure may identify bright portions and / or dark portions on the acquired image based on the identified illuminance information. Figure 4 Illustrates a first region (A) 410 and a second region (B) 420 identified as bright portions and a third region (C) 430 identified as a dark portion. The wearable device 200 according to an embodiment of the present disclosure may select all bright portions and / or dark portions in an image 400 obtained by at least one camera (e.g., second camera module 253) as regions for determining positions corresponding to illuminance information on at least one lens (e.g., display member 201). Optionally, the wearable device 200 according to an embodiment of the present disclosure may select some of the bright portions and / or dark portions in the image 400 obtained by at least one camera (e.g., second camera module 253) as regions for determining positions corresponding to illuminance information on at least one lens (e.g., display member 201). The image 400 according to an embodiment of the present disclosure may correspond to the real world viewed by a user wearing the wearable device 200.

[0100] In operation 320, the wearable device 200 (e.g., processor 120) according to an embodiment of the present disclosure may determine positions corresponding to the illuminance information on at least one lens (e.g., display member 201) based on the illuminance information identified in operation 310.

[0101] Figure 5a , Figure 5b , Figure 5c and Figure 5dIllustrates the function or operation of the wearable device 200 according to various embodiments of the present disclosure, which determines a position on at least one lens (e.g., the display member 201) whose light transmittance is to be adjusted, in order to adjust the light transmittance of at least one lens (e.g., the display member) included in the wearable device 200.

[0102] At least one camera (e.g., the second camera module 253) may be disposed at an upper end (e.g., the lens frame 202) of each of a plurality of lenses (e.g., the left-eye lens and the right-eye lens) of the wearable device 200 according to an embodiment of the present disclosure. In other words, the wearable device 200 according to another embodiment of the present disclosure may include a plurality of (e.g., two) camera modules. Regarding Figures 5a to 5d , based on the case where the wearable device 200 includes a plurality of camera modules, illustrates the function or operation of the wearable device 200 according to still another embodiment of the present disclosure, which determines a position on at least one lens (e.g., the display member 201) whose light transmittance is to be adjusted. The wearable device 200 according to still another embodiment of the present disclosure may position the image 400, the camera module 250, and the lens (e.g., the left-eye lens as the display member 201) in a virtual space such that the center (e.g., the first center 400a) of the image 400 acquired by at least one camera (e.g., the camera module 250 disposed at the upper end of the left-eye lens) and the center (e.g., the first center 400a) of the camera module 250 (e.g., the camera module 250 disposed at the upper end of the left-eye lens) are located on a straight line in the virtual space. In this case, as Figure 5bAs shown, the distance between the lens (e.g., display member 201) and the image 400 (e.g., real object) (e.g., “object distance”) can be much greater than the distance between the user 500's eyeball and the lens (e.g., display member 201) (e.g., “vertex distance”). For example, the distance between the lens (e.g., display member 201) and the image 400 (e.g., real object) (e.g., “object distance”) is infinite, and the distance between the user 500's eyeball and the lens (e.g., display member 201) (e.g., “vertex distance”) can be 5 cm. In this case, the center of the camera module 250 can be processed (e.g., treated) as the same as the center of the lens (e.g., display member 201) (e.g., second center 201a). Thus, when the illuminance information of the obtained image 400 is assigned to the lens (e.g., display member 201), the angle (e.g., x and / or y) formed by the center of the camera module 250 and the center (e.g., third center 410a) of at least one arbitrary point (e.g., first region 410 (e.g., light portion)) included in the first region 410 (e.g., light region) can be regarded as the angle formed by the center of the lens (e.g., display member 201) and the center (e.g., third center 410a) of the first region 410 (e.g., light region). The wearable device 200 according to an embodiment of the present disclosure can identify the coordinates of the eyeball image of the user 500 obtained using at least one camera (e.g., first camera module 251). For example, the wearable device 200 according to an embodiment of the present disclosure identifies the coordinates of the eyeball image by using an arbitrary point (e.g., the center of the eyeball image) included in the eyeball image of the user 500 obtained using at least one camera (e.g., first camera module 251) as a starting point. For example, the wearable device 200 according to an embodiment of the present disclosure is adapted to (e.g., arrange the image in a virtual space for calculation) position the identified coordinates of the eyeball image and the center of the lens (e.g., display member 201) on a line (e.g., flush with the ground). As Figure 5c As shown, based on the center coordinates of the user 500's eye, the wearable device 200 according to an embodiment of the present disclosure can project the angle (e.g., x and / or y) formed by the center of the camera module 250 and the center (e.g., third center 410a) of the first region 410 (e.g., light region) onto the lens (e.g., display member 201). According to the function or operation, the coordinates of the center (e.g., third center 410a) of the first region 410 (e.g., light region) can substantially become the same as the coordinates at the position (e.g., first position 201b) determined on the lens (e.g., display member 201), and the illuminance information of the center (e.g., third center 410a) of the first region 410 (e.g., light region) can be assigned to the position (e.g., first position 201b) determined on the lens (e.g., display member 201). AsFigure 5d As shown, the wearable device 200 according to another embodiment of the present disclosure can perform the reference operation similarly for multiple regions (for example, a first region (A) 410 and a second region (B) 420 identified as a bright portion and a third region (C) 430 identified as a dark portion). Figures 5a to 5c The functions or operations described. Through these functions or operations, the coordinates of at least one arbitrary point (e.g., the third center 410a, the fourth center 420a, and the fifth center 430a) included in the first area 410 to the third area 430 can be substantially the same as the coordinates of the positions (e.g., the first position 201b, the second position (i.e., the left eye lens 201c), and the third position (i.e., the right eye lens 201d)) determined on the lens (e.g., the display member 201), and thus, the illumination information of each of the plurality of areas (e.g., the first position 201b, the second position (i.e., the left eye lens 201c), and the third position (i.e., the right eye lens 201d)) can be calculated. The first area (A) 410 and the second area (B) 420 identified as the bright part and the third area (C) 430 identified as the dark part can be assigned to the lens (e.g., the display member 201). According to another embodiment of the present disclosure, the wearable device 200 can be configured to include the center of the camera module 250 and the first area 410 (e.g., The angle (e.g., θx and / or θy) formed by the center (e.g., the third center 410a) of the first area 410 (e.g., the bright area) is directly projected onto the lens (e.g., the display member 201) without recognizing the coordinates of the eyeball image of the user 500. According to another embodiment of the present disclosure, when the illuminance information of the acquired image 400 is assigned to the lens (e.g., the display member 201), the function or operation of acquiring the eyeball image and recognizing the coordinates of the acquired eyeball image can be omitted. According to another embodiment of the present disclosure, a plurality of arbitrary points included in the first area 410, the second area 420, and the third area 430 may be provided, for example, the arbitrary points are included in the boundaries of the first area 410, the second area 420, and the third area 430. In this case, the wearable device 200 according to an embodiment of the present disclosure may obtain the coordinate information of the points included in the boundaries of the first area 410, the second area 420, and the third area 430, thereby recognizing the sizes of the first area 410, the second area 420, and the third area 430.

[0103] Although for ease of description, Figures 5a to 5dAs an example, a case is shown where a lens (e.g., display member 201) and / or a lens (e.g., an EC (electrochromic) lens) for adjusting the light transmittance included in the lens (e.g., display member 201) has a rectangular shape. However, according to various embodiments of the present disclosure, the lens (e.g., display member 201) and / or the lens (e.g., an EC (electrochromic) lens) for adjusting the light transmittance included in the lens (e.g., display member 201) may have various shapes (e.g., circular or oval). Even in such a case, various functions or operations according to embodiments of the present disclosure may be equally applied to the lens (e.g., display member 201) configured to have various shapes (e.g., circular, etc.) and / or the lens (e.g., an EC lens) for adjusting the light transmittance included in the lens (e.g., display member 201).

[0105] Reference Figure 6a and Figure 6b , when an image 400 is acquired by one camera module (e.g., second camera module 253), the wearable device 200 according to an embodiment of the present disclosure may generate a left-eye image 440a cropped except for a part of the right region of the acquired image 400, and a right-eye image 440b cropped except for a part of the left region of the acquired image 400. According to an embodiment of the present disclosure, the degree of cropping (e.g., the size of the part of the right region and / or the part of the left region) may be predetermined. As Figure 6a shown, the wearable device 200 according to an embodiment of the present disclosure may perform the Figures 5a to 5d functions or operations described in Figure 6b by using the left-eye image 440a. As Figures 5a to 5dThe functions or operations described in . Through these functions or operations, the wearable device 200 according to an embodiment of the present disclosure can configure (e.g., assign the coordinates of the image 400 to the lens) each lens (e.g., the left-eye lens 201c and / or the right-eye lens 201d) such that the coordinates of the centers of the first region 410 to the third region 430 (e.g., the third center 410a, the fourth center 420a, and the fifth center 430a) correspond to specific positions (e.g., position A', position B', and / or position C') of the lens (e.g., the display member 201).

[0106] In operation 330, the wearable device 200 according to an embodiment of the present disclosure (e.g., the processor 120) may determine the average illuminance of an image based on the illuminance information corresponding to the position determined according to operation 320. The wearable device 200 according to an embodiment of the present disclosure may identify the illuminance value corresponding to the position (e.g., position A', position B', and / or position C') (e.g., 200 (lux) as the illuminance value of position A', 300 (lux) as the illuminance value of position B', and 10 (lux) as the illuminance value of position C') based on the illuminance information of the acquired image 400 according to operation 320. The wearable device 200 according to an embodiment of the present disclosure may determine the average illuminance value (e.g., 170 (lux)) based on the identified illuminance values. The wearable device 200 according to an embodiment of the present disclosure may determine the total transmittance of at least one lens (e.g., the display member 201) based on the determined average illuminance value (e.g., 170 (lux)). The wearable device 200 according to an embodiment of the present disclosure may determine the total transmittance of at least one lens (e.g., the display member 201) by using a look-up table stored in the wearable device 200 or obtained from an external electronic device (e.g., a server) that provides a defined relationship between the illuminance value and the transmittance. According to another embodiment of the present disclosure, when the current average illuminance value (e.g., 170 (lux)) is a relatively higher illuminance value than the previous average illuminance value, at least one lens (e.g., the display member 201) may be controlled to have a lower light transmittance than the previous light transmittance (e.g., the light transmittance at a time point before a specific time interval from the time point when an image 400 corresponding to the current user's gaze is acquired by at least one camera (e.g., the second camera module 253)). According to still another embodiment of the present disclosure, when the current average illuminance value (e.g., 170 (lux)) is a relatively lower illuminance value than the previous average illuminance value, at least one lens (e.g., the display member 201) may be controlled to have a higher light transmittance than the previous light transmittance (e.g., the light transmittance at a time point before a specific time interval from the time point when an image 400 corresponding to the current user's gaze is acquired by at least one camera (e.g., the second camera module 253)).

[0107] In operation 340, a wearable device 200 (e.g., processor 120) according to an embodiment of the present disclosure may compare illuminance information corresponding to a position determined according to operation 320 with an average illuminance. The wearable device 200 according to an embodiment of the present disclosure may compare illuminance values (e.g., 200 (lux) as the illuminance value of position A', 300 (lux) as the illuminance value of position B', and 10 (lux) as the illuminance value of position C') corresponding to the position determined according to operation 320 (e.g., position A', position B', and / or position C') with an average illuminance value (e.g., 170 (lux)). Operation 340 according to an embodiment of the present disclosure may be performed after adjusting a total light transmittance of at least one lens (e.g., display member 201).

[0108] In operation 350, a wearable device 200 (e.g., processor 120) according to an embodiment of the present disclosure may adjust a light transmittance of a part of at least one lens (e.g., display member 201) based on a result of the comparison according to operation 340. The wearable device 200 according to an embodiment of the present disclosure may adjust a light transmittance of a part of at least one lens (e.g., an EC lens included in display member 201) based on a look-up table in which a reduction ratio of the light transmittance according to a difference in illuminance values is defined. For example, when a difference in illuminance values is +30 (lux), the light transmittance of a part of at least one lens (e.g., display member 201) is adjusted such that the light transmittance is reduced by 5% from a current light transmittance (e.g., a voltage 5% greater than a current voltage applied to an electrode is applied). The wearable device 200 according to an embodiment of the present disclosure may adjust a light transmittance in a specified area (e.g., a rectangular area having position A' as a center and having specified horizontal and vertical lengths) including positions on at least one lens (e.g., display member 201) determined according to operation 320. Optionally, according to another embodiment of the present disclosure, when a size of an area of a bright part (e.g., first area 410 and second area 420) or a dark part (e.g., third area 430) is recognized, the wearable device 200 may also adjust a light transmittance of a part of an area (e.g., display member 201) including at least one lens corresponding to the size of the area of the bright part (e.g., first area 410 and second area 420) or the dark part (e.g., third area 430).

[0109] Figure 7 The principle of adjusting a light transmittance of a part of at least one lens (e.g., an EC lens included in display member 201) included in a wearable device according to an embodiment of the present disclosure is shown.

[0110] Reference Figure 7, a wearable device 200 (e.g., processor 120) according to an embodiment of the present disclosure may control the voltage applied to a specified area by using a plurality of electrodes (e.g., A1 to A5, B1 to B4), thereby reducing or increasing the light transmittance in the specified area. The wearable device 200 according to an embodiment of the present disclosure may apply a specified voltage to electrodes A5 and B2 to change the light transmittance in a specified area (e.g., the fourth area 710). The wearable device 200 according to an embodiment of the present disclosure may apply a specified voltage to electrodes A5 and B4 to change the light transmittance in a specified area (e.g., the fifth area 720). According to an embodiment of the present disclosure, a relatively high voltage may be applied to a specified electrode to reduce the light transmittance in a specified area, and a relatively low voltage may be applied to a specified electrode to increase the light transmittance in a specified area. The wearable device 200 according to an embodiment of the present disclosure may apply a voltage to a specified electrode based on a look-up table in which the relationship between the light transmittance and the voltage is defined. At least one lens (e.g., display member 201) according to an embodiment of the present disclosure may include an LCD. Regarding the LCD included in at least one lens according to an embodiment of the present disclosure, an LCD having a "polarizing plate - glass - TFT - liquid crystal - glass - polarizing plate" structure may be included in at least one lens. The wearable device 200 according to an embodiment of the present disclosure may adjust the light transmittance by adjusting the level of the voltage applied to the liquid crystal. The wearable device 200 may apply a voltage to the liquid crystal at a specified position based on a look-up table in which the relationship between the light transmittance and the voltage is defined. Based on these functions or operations, the light transmittance of a part (e.g., display member 201) of at least one lens included in the wearable device 200 may be controlled based on the position of an external light source (e.g., a real object) (e.g., controlling the lens such that the light transmittance of the part of the lens corresponding to the high-illuminance area on the captured image is reduced, and the light transmittance of the part of the lens corresponding to the low-illuminance area on the captured image is increased), thereby improving the visibility of an external object or a virtual object viewed by the user 500 through the wearable device 200.

[0111] In the wearable device 200 according to an embodiment of the present disclosure, there may be a case where the illuminance at a specified position (e.g., position B') is still high even after performing the functions or operations related to operation 350 (e.g., the case where the illuminance at the specified position (e.g., position B') exceeds a specified threshold illuminance value). In such a case, the wearable device 200 according to an embodiment of the present disclosure may also adjust (e.g., reduce) the light transmittance at the specified position (e.g., position B').

[0112] The wearable device 200 according to an embodiment of the present disclosure may detect the movement of the user's gaze or the movement of a part of the user's body (e.g., the head wearing the wearable device 200) during the execution of functions or actions related to operation 350. In this case, the positions determined according to operation 320 (e.g., position A', position B', and / or position C') may be moved based on the moving direction and moving speed of the user 500's line of sight. The wearable device 200 according to an embodiment of the present disclosure may identify the moving direction and moving speed of the user 500's gaze by analyzing an image obtained from at least one camera (e.g., the first camera module 251) configured to capture the user 500's gaze. The wearable device 200 according to an embodiment of the present disclosure may determine the moving direction and moving speed of the user's gaze or the movement of a part of the user's body (e.g., the head wearing the wearable device 200) based on values sensed by sensors (e.g., an IMU sensor, an acceleration sensor, and / or a gyro sensor) provided in the wearable device 200. According to an embodiment of the present disclosure, the functions or operations may be similarly applied even when an external light source moves.

When the wearable device 200 according to an embodiment of the present disclosure includes a plurality of cameras (e.g., the second camera module 253 provided around the left-eye lens 201c and the second camera module 253 provided around the right-eye lens 201d), the wearable device 200 may obtain illuminance information around the user 500 wearing the wearable device 200 (e.g., illuminance information around the left-eye lens 201c and illuminance information around the right-eye lens 201d) based on the histogram of each image captured by the plurality of cameras.

[0115] In operation 820, the wearable device 200 according to an embodiment of the present disclosure may determine whether the illuminance value around the first lens (e.g., the left-eye lens 201c) and the illuminance value around the second lens (e.g., the right-eye lens 201d) are different from each other. The wearable device 200 according to an embodiment of the present disclosure may determine whether the illuminance value around the first lens (e.g., the left-eye lens 201c) and the illuminance value around the second lens (e.g., the right-eye lens 201d) are different from each other based on whether the difference between the illuminance value around the first lens (e.g., the left-eye lens 201c) and the illuminance value around the second lens (e.g., the right-eye lens 201d) exceeds a threshold illuminance value.

[0116] When the illuminance value around the first lens (e.g., the left-eye lens 201c) and the illuminance value around the second lens (e.g., the right-eye lens 201d) are different from each other, in operation 830, the wearable device 200 according to an embodiment of the present disclosure may determine that the light transmittance of the first lens (e.g., the left-eye lens 201c) and the light transmittance of the second lens (e.g., the right-eye lens 201d) are different from each other.

In operation 850, the wearable device 200 according to an embodiment of the present disclosure may adjust the light transmittance of at least one lens (e.g., the left-eye lens 201c and / or the right-eye lens 201d) based on the light transmittance determined according to operation 830.

[0117] When the illuminance value around the first lens (e.g., the left-eye lens 201c) and the illuminance value around the second lens (e.g., the right-eye lens 201d) are equal to each other (e.g., operation 820 - No), in operation 840, the wearable device 200 according to an embodiment of the present disclosure may determine that the light transmittance of the first lens (e.g., the left-eye lens 201c) and the light transmittance of the second lens (e.g., the right-eye lens 201d) are equal to each other.

In operation 850, the wearable device 200 according to an embodiment of the present disclosure may adjust the light transmittance of at least one lens (e.g., the left-eye lens 201c and / or the right-eye lens 201d) based on the light transmittance determined according to operation 830.

[0118] The wearable device 200 according to an embodiment of the present disclosure may configure the light transmittance of at least one lens (e.g., the display member 201) corresponding to the area where the virtual object is displayed to be lower than the light transmittance of other areas in the at least one lens (e.g., the display member 201).
