[0060] In one embodiment, the wearable electronic device (200) may have a plurality of displays (e.g., a first display (215) (e.g., a first glass), a second display (216) (e.g., a second glass)) arranged in response to a rear direction of the wearable electronic device (200) (e.g., a y-axis direction, a direction opposite to a user's gaze direction). For example, a first display (215) corresponding to a user's left eye and a second display (216) corresponding to the user's right eye may be arranged on a second side (212) (e.g., a rear side) of the wearable electronic device (200). For example, when the wearable electronic device (200) is worn on a user's face, the first display (215) may be arranged in response to the user's left eye, and the second display (216) may be arranged in response to the user's right eye.

[0061] In one embodiment, a user of a wearable electronic device (200) can view a foreground (e.g., a real image) of an external object (e.g., a subject) through a first display (215) and a second display (216). The wearable electronic device (200) can implement augmented reality by displaying a virtual image superimposed on the foreground (e.g., a real image) of the external object.

[0062] In one embodiment, the first display (215) and the second display (216) may include projection-type transparent displays. The first display (215) and the second display (216) may each form a reflective surface as a transparent plate (or transparent screen), and an image generated from the wearable electronic device (200) may be reflected (e.g., total internal reflection) through the reflective surface and incident on the user's left and right eyes. In one embodiment, the first display (215) may include an optical waveguide that transmits light generated from a light source of the wearable electronic device (200) to the user's left eye. For example, the optical waveguide may be formed of glass, plastic, or a polymer material, and may include a nano-pattern (e.g., a grating structure or a mesh structure having a polygonal or curved shape) formed on the inside or surface of the first display (215). The optical waveguide may include at least one diffractive element (e.g., a diffractive optical element (DOE), a holographic optical element (HOE)) or at least one reflective element (e.g., a reflective mirror). The optical waveguide may guide display light emitted from a light source toward a user's eye using at least one diffractive element or reflective element included in the optical waveguide. In various embodiments, the diffractive element may include an input / output optical element, and the reflective element may include a total internal reflection (TIR). For example, light emitted from a light source may be guided along an optical path to the optical waveguide through an input optical element, and light traveling inside the optical waveguide may be guided toward a user's eye through an output optical element. The second display (216) may be implemented in substantially the same manner as the first display (215).

[0063] According to various embodiments, the first display (215) and the second display (216) may include, for example, a liquid crystal display (LCD), a digital mirror device (DMD), a liquid crystal on silicon (LCoS), an organic light emitting diode (OLED), or a micro light emitting diode (micro LED).

[0064] In one embodiment, the wearable electronic device (200) may have a plurality of gaze tracking cameras (e.g., a first gaze tracking camera (231) and a second gaze tracking camera (232)) disposed at least partially on the second surface (212). For example, the plurality of gaze tracking cameras (231, 232) may track eye movements of a user. The first gaze tracking camera (231) may track eye movements of the user, and the second gaze tracking camera (232) may track eye movements of the user. The plurality of gaze tracking cameras (231, 232) may track eye movements of the user using, for example, at least one of an EOG sensor (electro-oculography or electrooculogram), a coil system, a dual Purkinje system, bright pupil systems, or dark pupil systems. In one embodiment, the wearable electronic device (200) can determine the direction in which the user is looking based on the movement of the eyeballs tracked using a plurality of eye tracking cameras (231, 232).

[0065] In one embodiment, a plurality of face recognition cameras (e.g., a first face recognition camera (235), a second face recognition camera (236)) may be disposed at least partially on the second face (212) of the wearable electronic device (200). For example, the plurality of face recognition cameras (235, 236) may recognize the user's face when the wearable electronic device (200) is worn on the user's face. In one embodiment, the wearable electronic device (200) may also determine whether the wearable electronic device (200) is worn on the user's face using the plurality of face recognition cameras (235, 236).

[0066] Although not shown in FIGS. 2A and 2B according to one embodiment, the wearable electronic device (200) may include a forehead support that contacts the user's forehead and a rear band that contacts the back of the user's head. The user may wear the wearable electronic device (200) by adjusting the length of the rear band relative to the forehead support.

[0068] Referring to FIG. 3A, a wearable electronic device (200) may include a plurality of display modules. A first display module among the plurality of display modules may include a first display (215) and a first lens. A second display module among the plurality of display modules may include a second display (216) and a second lens. In one embodiment, the first display (215) and the first lens may be arranged to correspond to the user's left eye, and the second display (216) and the second lens may be arranged to correspond to the user's right eye.

[0069] In one embodiment, the wearable electronic device (200) may be equipped with a vision correction lens (e.g., the vision correction lens (315) of FIG. 3B). For example, the vision correction lens (315) may be equipped on the wearable electronic device (200) to correct the user's vision. For example, the vision correction lens (315) may be equipped on the wearable electronic device (200) in a first direction (e.g., the -y-axis direction).

[0070] In one embodiment, the wearable electronic device (200) may further be equipped with a cover member (300) for covering the vision correction lens (315). For example, the cover member (300) may be mounted (305) on the vision correction lens (315) in a first direction (e.g., -y-axis direction).

[0071] FIG. 3b is a drawing for explaining a vision correction lens (315) and a cover member (300) covering the vision correction lens according to one embodiment of the present disclosure.

[0072] Referring to Fig. 3b, <310> is a drawing illustrating a vision correction lens (315). In one embodiment, the vision correction lens (315) may be detachable from the wearable electronic device (200). For example, the vision correction lens (315) may be mounted on the wearable electronic device (200) by the user to correct the user's vision. In another example, the vision correction lens (315) may be detachable from the wearable electronic device (200) by the user when the user's vision correction is not required or when the vision correction lens is replaced with another vision correction lens.

[0073] According to one embodiment <330> and <350> is a drawing illustrating a cover member (300). As seen in FIG. 3a, the cover member (300) can be mounted (305) on a vision correction lens (315) in a first direction (e.g., the -y-axis direction of FIG. 3a).

[0074] In one embodiment, a first side (e.g., a side facing a first direction (e.g., a -y-axis direction)) of the cover member (300) may include a designated pattern (335, 355). In one embodiment, the designated pattern (335) may include: <330> As shown in , it can be formed on the entire first surface of the cover member (300). However, it is not limited thereto. For example, the specified pattern (335) <350> As shown in , it may be formed in at least a portion of the first surface of the cover member (300).

[0075] In one embodiment, the designated pattern (335, 355) of the cover member (300) may include a grid pattern. For example, the grid pattern may mean that grids of a designated size or shape are arranged at designated intervals. However, the present invention is not limited thereto, and considering that distortion generally occurs in the outer region of a lens, grids of a designated shape may be arranged at a first interval in the central region of the cover member (300), and grids of a designated shape may be arranged at a second interval smaller than the first interval in regions other than the central region of the cover member (300).

[0076] In one embodiment, the designated pattern (335, 355) of the cover member (300) can be used to generate correction values ​​for correcting a display (e.g., the first display (215) and the second display (216) of FIG. 2B).

[0077] With respect to a method for calculating a correction value for correcting a display (215, 216) using a designated pattern (335, 355) of the aforementioned cover member (300), various embodiments can be described in FIGS. 4 to 17 described below.

[0105] According to one embodiment, operations 505 to 520 of FIG. 5 may be understood to be performed (or executed) individually or collectively by a processor (e.g., the processor (450) of FIG. 4 (or at least one processor)) of a wearable electronic device (e.g., the wearable electronic device (200) of FIGS. 2A and 2B).

[0106] Referring to FIG. 5, in operation 505, the processor (450) may obtain a first image corresponding to a designated pattern (e.g., designated patterns (335, 355) of FIG. 3B) of the cover member (300) using a first camera (e.g., the first camera (441) of FIG. 4) while the wearable electronic device (200) is equipped with a vision correction lens (e.g., vision correction lens (315) of FIG. 3B) and a cover member (e.g., cover member (300) of FIGS. 3A and 3B) covering the vision correction lens (315). For example, the wearable electronic device (200) may be equipped with a vision correction lens (315) for correcting the user's vision. For example, the vision correction lens (315) may be mounted on the display (430) of the wearable electronic device (200) in a first direction (e.g., the -y-axis direction of FIG. 3A). The cover member (300) may be mounted on the vision correction lens (315) in the first direction (e.g., the -y-axis direction of FIG. 3A). In one embodiment, the designated pattern (335, 355) of the cover member (300) may be formed (or included) on a first surface of the cover member (300) (e.g., a surface facing the -y-axis direction of FIG. 3A).

[0107] In one embodiment, the first camera (441) may include a plurality of gaze tracking cameras, for example, a first gaze tracking camera (231) and a second gaze tracking camera (232), as illustrated in FIG. 2B.

[0110] At least some areas that do not satisfy the specified conditions according to one embodiment can be identified as areas where singular points are detected. The processor (450) can compare the first image acquired through the first camera (441) with a reference image stored in the memory (420) to determine whether a singular point is detected. For example, a reference image corresponding to a specified pattern (335, 355) included in the cover member (300) can be pre-stored in a memory (e.g., the memory (420) of FIG. 4).

[0111] In one embodiment, the first image may be divided into a plurality of regions, and the processor (450) may determine, based on the comparison result, whether a region in which a singular point is detected exists among the plurality of regions in the acquired first image.

However, the singular point is not limited thereto, and may include a degree of distortion, for example, a degree of warpage (e.g., linearity) of a pattern. Alternatively, the singular point may include a size of a pattern in the first image and / or a distance between patterns in the first image.

[0112] In one embodiment, the processor (450) may, in operation 515, set the characteristic value of the vision correction lens (315) for at least some areas to the first characteristic value if there are at least some areas that do not satisfy the specified condition.

[0113] In one embodiment, the processor (450) may, in operation 520, set a characteristic value of the vision correction lens (315) for at least some other area among the plurality of areas that satisfies a specified condition to a second characteristic value that is different from the first characteristic value.

[0114] The characteristic values ​​of the vision correction lens (315) according to one embodiment may include diopters.

[0115] In one embodiment, although not shown, the processor (450) may output a notification guiding the attachment / detachment of the cover member (300) after setting the characteristic value of the vision correction lens (315) to the second characteristic value. For example, the processor (450) may provide a notification (e.g., a notification guiding the attachment / detachment of the cover member (300)) to the user through a speaker (e.g., an audio output module (155) of FIG. 1), a light-emitting element (e.g., an LED), and / or a haptic module (e.g., a haptic module (179) of FIG. 1) included in the wearable electronic device (200). For example, the processor (450) may provide a notification (e.g., a notification guiding the attachment / detachment of the cover member (300)) to another electronic device (e.g., an electronic device (102) of FIG. 1) that is communicatively connected to the wearable electronic device (200) through the communication circuit (410).

[0116] FIG. 6 is a flowchart illustrating a method for setting a characteristic value of at least some area that does not satisfy a specified condition in a first image to a first characteristic value, according to one embodiment of the present disclosure.

[0117] In the following embodiments, the operations of FIG. 6 may be performed sequentially, but are not necessarily performed sequentially. For example, the order of the operations of FIG. 6 may be changed, and at least two operations may be performed in parallel.

[0118] According to one embodiment, operations 605 and 610 of FIG. 6 may be understood to be performed (or executed) individually or collectively by a processor (e.g., the processor (450) of FIG. 4 (or at least one processor)) of a wearable electronic device (e.g., the wearable electronic device (200) of FIGS. 2A and 2B).

[0119] FIG. 6 according to various embodiments may be an operation that embodies operation 515 of FIG. 5 described above.

[0120] Referring to FIG. 6, the processor (450) may compare a first image (e.g., a first image acquired through a first camera (e.g., a first camera (441) of FIG. 4)) and a reference image corresponding to a specified pattern of a cover member (e.g., a cover member (300) of FIG. 3A) in operation 605. The reference image corresponding to the specified pattern of the cover member (300) may be pre-stored in a memory (e.g., a memory (420) of FIG. 2).

[0121] The processor (450) can compare the first image with a reference image stored in the memory (420) to determine whether a singular point is detected. Based on the comparison result, the processor (450) can determine whether an area in which a singular point is detected exists among a plurality of areas in the first image. According to one embodiment, the singular point may include a flare caused by the vision correction lens (315), the size of a pattern in the first image, the degree of warpage of the pattern (e.g., linearity), and / or the distance between patterns.

[0122] In one embodiment, the processor (450) may set, in operation 610, a characteristic value of at least some areas in which a singularity is detected among a plurality of areas in the first image as a first characteristic value.

[0123] In one embodiment, distortion may generally occur in the outer region of the lens, and accordingly, singular points may be detected in the outer region of the first image corresponding to the specified pattern of the cover member (300).

[0124] As seen in FIGS. 5 and 6, the processor (450) sets different characteristic values ​​to a plurality of regions constituting the first image (e.g., sets the characteristic value of the vision correction lens (315) for the outer region of the first image (e.g., the outer region excluding the center region (e.g., the region where a singularity is detected)) as the first characteristic value, and sets the characteristic value of the vision correction lens (315) for the center region of the first image differently as the second characteristic value), thereby providing an image suitable for a user wearing the wearable electronic device (200).

[0125] The operations of FIGS. 5 and 6 according to various embodiments may be performed at the time of booting the wearable electronic device (200), but are not limited thereto.

[0126] FIG. 7 and FIG. 8 are drawings for explaining a method for checking the characteristics of a vision correction lens (315) according to one embodiment of the present disclosure.

[0127] Fig. 7 <710> and <750> Referring to FIG. 2A and FIG. 2B , a wearable electronic device (e.g., a wearable electronic device (200) of FIGS. 2A and 2B ) may have a display (715) (e.g., a first display (215) and a second display (216) of FIGS. 2B and 3 , a display (430) of FIG. 4 ) disposed in response to a rear direction (e.g., a y-axis direction) of the wearable electronic device (200).

[0128] In one embodiment, the wearable electronic device (200) may be equipped with a vision correction lens (e.g., the vision correction lens (315) of FIG. 3B) for correcting the user's vision. The vision correction lens (315) may be mounted on the wearable electronic device (200) in a first direction (e.g., the -y-axis direction) (e.g., mounted on the display (715) of the wearable electronic device (200). The wearable electronic device (200) may further be equipped with a cover member (300) for covering the vision correction lens (315). For example, the cover member (300) may be mounted on the vision correction lens (315) in a first direction (e.g., the -y-axis direction). A first surface (e.g., a surface facing the -y-axis direction) of the cover member (300) may have a designated pattern (730) (e.g., a designated pattern (335, 355) of FIG. 3b) formed (or included).

[0129] In one embodiment, a processor (e.g., processor (450) of FIG. 4) can use a gaze tracking camera (725) (e.g., first gaze tracking camera (231) and second gaze tracking camera (232) of FIG. 2B) to obtain an image corresponding to a designated pattern (730) of a cover member (300).

[0130] In one embodiment, the vision correction lens (315) may change the size of an image (e.g., the size of a pattern included in the image) acquired through the eye tracking camera (725) at the same location due to differences in optical properties (e.g., refractive index and / or magnification) of the vision correction lens (315). For example, in FIG. 7 <710> and <750> Referring to FIG. 7 , the distance (735, 755) between the gaze tracking camera (725) and the designated pattern (730) may be the same, but the image acquired through the gaze tracking camera (725) of the vision correction lens (315) may be different depending on the optical characteristics of the vision correction lens (315), for example, the refractive index and / or magnification. In this regard, this will be examined in more detail in FIG. 8 described below.

[0131] FIG. 8 according to one embodiment illustrates an image acquired through a gaze tracking camera (725).

[0132] As discussed above, the processor (450) can recognize changes in the size of the image (e.g., the size of the pattern included in the image) and determine the characteristic value (e.g., diopter) of the vision correction lens (315).

[0133] For example, in Fig. 7 <710> As illustrated, the processor (450) can acquire an image through the gaze tracking camera (725) in a state where the gaze tracking camera (725) and the designated pattern (730) are separated by a first distance (735). For example, the distance from the first point to the second point of the designated pattern in the image may have a first distance (810). Based on the confirmation that the distance from the first point to the second point of the designated pattern in the image has the first distance (810), the processor (450) can confirm the characteristic value of the vision correction lens (315) as a first characteristic value (e.g., -1).

[0134] For another example, in Fig. 7 <750> As illustrated, an image can be acquired through the gaze tracking camera (725) when the gaze tracking camera (725) and the designated pattern (730) are spaced apart by a first distance (755). For example, a distance from a first point to a second point in the designated pattern in the image can have a second distance (820). Based on the determination that the distance from the first point to the second point in the designated pattern in the image has the second distance (820), the processor (450) can determine the characteristic value of the vision correction lens (315) as a second characteristic value (e.g., +1) (e.g., a second characteristic value (e.g., +1) that is different from the first characteristic value (e.g., -1)).

[0135] Although it has been described in FIGS. 7 and 8 according to one embodiment that the change in the size of the image (e.g., the size of the pattern included in the image) is recognized to correct the characteristic value (e.g., diopter) of the vision correction lens (315), it is not limited thereto. For example, the height of the vision correction lens (315) may be designed differently according to the characteristic value of the vision correction lens (315) and mounted on the wearable electronic device (200). In this case, the change in the size of the image (e.g., the size of the pattern included in the image) may be clearly distinguished according to the height of the vision correction lens (315), and the processor (450) may also check the characteristic value of the vision correction lens (315) based on the height of the vision correction lens (315).

[0136] FIGS. 9A, 9B, and 9C are drawings for explaining a method for checking the characteristics of a vision correction lens (315) according to one embodiment of the present disclosure.

[0137] Referring to FIGS. 9A, 9B, and 9C, a processor (e.g., a processor (450) of FIG. 4) of a wearable electronic device (e.g., a wearable electronic device (200) of FIGS. 2A and 2B) can determine the characteristics of a vision correction lens (e.g., a vision correction lens (315) of FIG. 3B) for correcting the vision of a user mounted on the wearable electronic device (200) based on the location of a flare.

[0138] In one embodiment, FIG. 9a <910> When the vision correction lens (315) has a first characteristic value (e.g., +1), an image corresponding to a designated pattern (e.g., a designated pattern (730) of FIG. 7) of a cover member (e.g., a cover member (300) of FIG. 3b) obtained by using a gaze tracking camera (e.g., a gaze tracking camera (725) of FIG. 7) is shown. FIG. 9a <920> silver <910> This is an enlarged image of a portion of the image (915).

[0139] In one embodiment, when the vision correction lens (315) has a first characteristic value (e.g., +1), a plurality of flares (925) may occur, as illustrated in FIG. 9A. For example, the plurality of flares (925) may include a first flare (9251) occurring at a first location on the inner surface of the vision correction lens (315) and a second flare (9252) occurring at a first location on the outer surface of the vision correction lens (315). However, the present invention is not limited thereto.

[0140] In one embodiment, the inner surface of the vision correction lens (315) may mean, for example, a surface facing in a direction opposite to the direction (e.g., the y-axis direction in FIG. 3A) toward the displays (e.g., the first display (215) and the second display (216)) when the vision correction lens (315) is mounted on the displays. In one embodiment, the outer surface of the vision correction lens (315) may mean, for example, a surface facing in a direction (e.g., the -y-axis direction in FIG. 3A) toward the displays (e.g., the first display (215) and the second display (216)) when the vision correction lens (315) is mounted on the displays.

[0141] In one embodiment, FIG. 9b <930> When the vision correction lens (315) has a second characteristic value (e.g., -1), an image corresponding to a designated pattern (730) of the acquired cover member (300) is shown using the eye tracking camera (725). FIG. 9b <940> silver <930> This is an enlarged image of a portion of the image (935).

[0142] In one embodiment, when the vision correction lens (315) has a second characteristic value (e.g., -1), a plurality of flares (945) may occur, as illustrated in FIG. 9B . For example, the plurality of flares (945) may include a second flare (9451) occurring at a second location on the inner surface of the vision correction lens (315) and a second flare (9452) occurring at a second location on the outer surface of the vision correction lens (315). However, the present invention is not limited thereto. In one embodiment, the second location on the inner surface of the vision correction lens (315) may be different from the first location on the inner surface of the vision correction lens (315). The second location on the outer surface of the vision correction lens (315) may be different from the first location on the outer surface of the vision correction lens (315).

[0143] In one embodiment, FIG. 9c <950> In the case where the vision correction lens (315) has a third characteristic value (e.g., -3), an image corresponding to a designated pattern (730) of the acquired cover member (300) is shown using the eye tracking camera (725). FIG. 9c <960> silver <950> This is an enlarged image of a portion of the image (955).

[0144] In one embodiment, when the vision correction lens (315) has a third characteristic value (e.g., -3), a plurality of flares (965) may occur, as illustrated in FIG. 9C . For example, the plurality of flares (965) may include a third flare (9651) occurring at a third location on the inner surface of the vision correction lens (315) and a third flare (9652) occurring at a third location on the outer surface of the vision correction lens (315). However, the present invention is not limited thereto. In one embodiment, the third location on the inner surface of the vision correction lens (315) may be different from the first location and the second location on the inner surface of the vision correction lens (315). The third location on the outer surface of the vision correction lens (315) may be different from the first location and the second location on the outer surface of the vision correction lens (315).

[0145] According to one embodiment, the characteristic values ​​of the vision correction lens (315) for an area where multiple flares are detected as seen in FIGS. 9A, 9B, and 9C may be different from the characteristic values ​​of the vision correction lens (315) for an area where multiple flares are not detected.

[0146] As seen in FIGS. 9A, 9B, and 9C, the processor (450) can determine a characteristic value (e.g., diopter) of the vision correction lens (315) based on the location of the flare occurring on the inner and / or outer surface of the vision correction lens (315), and can correct the display (430) based on the determined characteristic value of the vision correction lens (315).

[0147] FIG. 10 is a drawing for explaining a method for checking the characteristics of a vision correction lens (315) according to one embodiment of the present disclosure.

[0148] Referring to FIG. 10, a wearable electronic device (e.g., the wearable electronic device (200) of FIGS. 2A and 2B) may be equipped with a vision correction lens (e.g., a vision correction lens (315) of FIG. 3B) for correcting a user's vision and a cover member (e.g., a cover member (300) of FIG. 3B) for covering the vision correction lens (315). A first surface (e.g., a surface facing the -y-axis direction of FIG. 3A) of the cover member (300) may have a designated pattern (e.g., a designated pattern (730) of FIG. 7) formed (or included).

[0149] In one embodiment, a processor (e.g., processor (450) of FIG. 4) can acquire an image corresponding to a designated pattern (730) of a cover member (300) using a gaze tracking camera (e.g., gaze tracking camera (725) of FIG. 7). The processor (450) can verify the linearity of the image acquired through the gaze tracking camera (725) (e.g., linearity of lines constituting the pattern within the image). For example, the processor (450) can verify the linearity of lines (1005) constituting the pattern within the image by verifying whether the lines (1005) constituting the pattern within the image are straight lines. In one embodiment, a region (1015, 1025) having nonlinearity other than a straight line (1010) (e.g., a region where a line is curved rather than a straight line) may be detected in some region of a line (1005) forming a pattern within an image, and a characteristic value (e.g., diopter) of a vision correction lens (315) may be set for the region (1015, 1025) having nonlinearity, and the display (430) may be corrected based on the set characteristic value of the vision correction lens (315). According to one embodiment, the characteristic value of the vision correction lens (315) for the region (1015, 1025) having nonlinearity as seen in FIG. 10 may be different from the characteristic value of the vision correction lens (315) for the region excluding the region (1015, 1025) having nonlinearity.

[0150] In FIG. 10 according to one embodiment, a straight line (1010) is shown to facilitate the description of a configuration for checking the linearity of a line (1005) forming a pattern within an image (e.g., checking whether the line is a straight line or a curved line), and in reality, the straight line (1010) may not be shown.

[0151] FIG. 11 is a drawing for explaining a method of performing a function of a wearable electronic device (200) by confirming the characteristics of a vision correction lens (315) according to one embodiment of the present disclosure.

[0152] Referring to FIG. 11, a wearable electronic device (e.g., the wearable electronic device (200) of FIGS. 2A and 2B) may be equipped with a vision correction lens (e.g., a vision correction lens (315) of FIG. 3B) for correcting a user's vision and a cover member (e.g., a cover member (300) of FIG. 3B) for covering the vision correction lens (315). A designated pattern (e.g., a designated pattern (730) of FIG. 7) may be formed (or included) on a first surface (e.g., a surface facing the -y-axis direction of FIG. 3A) of the cover member (300).

[0153] In one embodiment, a processor (e.g., processor (450) of FIG. 4) may acquire an image corresponding to a designated pattern (730) of a cover member (300) using an eye-tracking camera (e.g., eye-tracking camera (725) of FIG. 7). The processor (450) may identify an area where a singular point is detected in the image acquired through the eye-tracking camera (725). For example, in one embodiment, the processor (450) may compare a reference image corresponding to the designated pattern (730) stored in a memory (e.g., memory (420) of FIG. 4) with an image acquired through the eye-tracking camera (725) to identify an area where a singular point is detected. In one embodiment, the singular point may include a flare caused by a vision-correcting lens (315), a size of a pattern in the first image, a degree of warpage (e.g., linearity) of the pattern, and / or a distance between patterns.

[0154] Assuming that the singular points in FIG. 11 according to one embodiment are flares caused by the vision correction lens (315), the processor (450) can detect a plurality of singular points (1105, 1110, 1115, 1120, 1125, 1130) in the image illustrated in FIG. 11. The processor (450) can perform a correction (e.g., masking) to exclude the detected plurality of singular points (1105, 1110, 1115, 1120, 1125, 1130) (e.g., excluding (or removing) the plurality of singular points (1105, 1110, 1115, 1120, 1125, 1130) by judging them as unnecessary in the vision correction lens (315), and then perform a function of the wearable electronic device (200). For example, the functionality of the wearable electronic device (200) may include a gaze tracking function and / or a user authentication function (e.g., an iris authentication function). Accordingly, errors that may occur during the gaze tracking function and / or the user authentication function (e.g., an iris authentication function) can be prevented.

[0155] FIG. 12 and FIG. 13 are drawings for explaining a method for checking whether a vision correction lens (315) is mounted according to one embodiment of the present disclosure.

[0156] Fig. 12 <1210> Referring to FIG. 2A and FIG. 2B , a wearable electronic device (e.g., a wearable electronic device (200) of FIGS. 2A and 2B ) may have a display (715) (e.g., a first display (215) and a second display (216) of FIGS. 2B and 3 , a display (430) of FIG. 4 ) disposed in response to a rear direction (e.g., a y-axis direction) of the wearable electronic device (200).

[0157] In one embodiment, a wearable electronic device (200) may be equipped with a vision correction lens (e.g., a vision correction lens (315) of FIG. 3B) for correcting a user's vision. The vision correction lens (315) may be mounted on the wearable electronic device (200) in a first direction (e.g., in the -y-axis direction). The wearable electronic device (200) may further be equipped with a cover member (300) for covering the vision correction lens (315). For example, the cover member (300) may be mounted on the vision correction lens (315) in a first direction (e.g., in the -y-axis direction). A designated pattern (730) (e.g., a designated pattern (335, 355) of FIG. 3B) may be formed (or included) on a first surface (e.g., a surface facing the -y-axis direction) of the cover member (300).

[0158] Fig. 12 <1250> Referring to FIG. 12, <1210> In comparison, the wearable electronic device (200) may not be equipped with a vision correction lens (315).

[0159] In one embodiment, a processor (e.g., processor (450) of FIG. 4) can use a gaze tracking camera (725) (e.g., first gaze tracking camera (231) and second gaze tracking camera (232) of FIG. 2B) to obtain an image corresponding to a designated pattern (730) of a cover member (300).

[0160] FIG. 13 according to various embodiments <1310> is also 12 <1210> This is a drawing showing an image acquired through a gaze tracking camera (725) in the structure. Fig. 13 <1350> is also 12 <1250> This is a drawing showing an image acquired through a gaze tracking camera (725) in a structure.

[0161] Referring to FIGS. 12 and 13, the size of the pattern included in the image and / or the spacing of the pattern may be different through the eye tracking camera (725) depending on whether the vision correction lens (315) is mounted. For example, if the wearable electronic device (200) is equipped with the vision correction lens (315) (e.g., FIG. 12) <1210> (See), the distance between the gaze tracking camera (725) and the designated pattern (730) may have a first distance (1215). For another example, if the wearable electronic device (200) is not equipped with a vision correction lens (315) (e.g., FIG. 12). <1250> (Reference), the distance between the gaze tracking camera (725) and the designated pattern (730) may have a second distance (1255) that is shorter than the first distance (1215).

[0162] In one embodiment, when the wearable electronic device (200) is equipped with a vision correction lens (315), the size of the pattern included in the image (e.g., FIG. 13) when the distance between the gaze tracking camera (725) and the designated pattern (730) has a first distance (1215) <1310> (Reference) (or the spacing of the pattern included in the image) is the size of the pattern included in the image (e.g., FIG. 13) when the distance between the eye tracking camera (725) and the designated pattern (730) has the second distance (1255) as the wearable electronic device (200) is not equipped with a vision correction lens (315). <1350> (or the spacing of the patterns contained within the image).

[0163] For example, when comparing based on the straight line (1325, 1330), Fig. 13 <1310> The distance of the pattern according to may be the third distance (1315), and in FIG. 13 <1350> The distance between patterns according to the fourth distance (1355) may be greater than the third distance (1315). The processor (450) may determine whether a vision correction lens (315) is mounted based on the distance between patterns in the image.

[0164] FIG. 14 is a drawing for explaining a method for checking whether a vision correction lens (315) is mounted according to one embodiment of the present disclosure.

[0165] Referring to FIG. 14, a processor (e.g., processor (450) of FIG. 4) of a wearable electronic device (e.g., wearable electronic device (200) of FIGS. 2A and 2B) can determine whether a vision correction lens (e.g., vision correction lens (315) of FIG. 3B) for correcting the user's vision is mounted. For example, as discussed above in FIG. 12, the wearable electronic device (200) is mounted with a vision correction lens (315) (e.g., processor (450) of FIG. 12). <1210> (See) or may not be equipped with a vision correction lens (315) (e.g., FIG. 12). <1250> reference).

[0166] In one embodiment, the wearable electronic device (200) may obtain an image corresponding to the specified pattern (730) of the cover member (300) of FIG. 3B) using an eye tracking camera (e.g., an eye tracking camera (725) of FIG. 7) while the wearable electronic device (200) is equipped with a cover member (e.g., an eye tracking camera) including a specified pattern (730) of FIG. 7). The processor (450) may identify an area where a singular point is detected in the image acquired through the eye tracking camera (725). For example, the processor (450) may compare a reference image corresponding to the specified pattern (730) stored in a memory (e.g., a memory (420) of FIG. 4) with the image acquired through the eye tracking camera (725) to identify an area where a singular point is detected. In one embodiment, the singular point may include a flare caused by a vision correction lens (315).

[0167] According to one embodiment, FIG. 14 <1410> In the image shown in , a plurality of singular points (1415, 1420) can be detected. In this case, the processor (450) can confirm that the wearable electronic device (200) is equipped with a vision correction lens (315) based on detecting the plurality of singular points (1415, 1420). In accordance with one embodiment, FIG. 14 <1450> In the image shown in , singular points may not be detected. For example, in FIG. 14 <1410> In the image shown in Fig. 14, multiple singular points (1415, 1420) correspond to multiple areas detected. <1450> Multiple areas of the image shown in can be confirmed. Based on the fact that no singular points are detected at the same location in the images, the processor (450) can confirm that the wearable electronic device (200) is not equipped with a vision correction lens (315).

[0168] As seen in FIGS. 12, 13, and 14, the processor (450) acquires an image corresponding to a designated pattern (730) of the cover member (300) through the gaze tracking camera (725), and based on the size of the acquired image (e.g., the size of the pattern included in the image or the spacing of the pattern included in the image) and / or whether a singular point is detected in the image, accurately determines whether a vision correction lens (315) is mounted, and corrects a characteristic value (e.g., diopter) of the vision correction lens (315).

[0169] FIG. 15 is a flowchart illustrating a method of correcting a display (430) based on the characteristics of a vision correction lens (315), according to one embodiment of the present disclosure.

[0170] In the following embodiments, the operations of FIG. 15 may be performed sequentially, but are not necessarily performed sequentially. For example, the order of the operations of FIG. 15 may be changed, and at least two operations may be performed in parallel.

[0171] According to one embodiment, operations 1505 to 1515 of FIG. 15 may be understood to be performed (or executed) individually or collectively by a processor (e.g., the processor (450) of FIG. 4 (or at least one processor)) of a wearable electronic device (e.g., the wearable electronic device (200) of FIGS. 2A and 2B).

[0172] FIG. 15 according to various embodiments may be additional operations of the aforementioned FIG. 5.

[0173] Referring to FIG. 15, in operation 1505, the processor (450) may calculate a first correction value for correction of a display (e.g., display (430) of FIG. 4) based on a first characteristic value, which is a characteristic value of at least some areas among a plurality of areas in a first image that do not satisfy a specified condition.

[0174] In one embodiment, the processor (450) may, in operation 1510, calculate a second correction value for correction of the display (430) based on a second characteristic value that is a characteristic value of at least some other region among a plurality of regions in the first image that satisfies a specified condition.

[0175] In one embodiment, the processor (450) may, in operation 1515, correct the display (430) based on the calculated first correction value and the second correction value, and display a second image acquired through a second camera (e.g., the second camera (443) of FIG. 4). For example, the second image may include an actual image or an image in which a virtual image is superimposed on an actual image. However, the present invention is not limited thereto, and the processor (450) may also correct the display (430) based on the calculated first correction value and the second correction value, and display content (e.g., a virtual image) stored in a memory (e.g., the memory (420) of FIG. 4).

[0176] In FIG. 15 according to one embodiment, the first correction value and the second correction value are described as being used to correct the display (430), but the present invention is not limited thereto. The first correction value and the second correction value may be used to correct images for performing a function of the wearable electronic device (200), for example, a gaze tracking function and / or a user authentication function (e.g., an iris authentication function). For example, the processor (450) may acquire images including an eye of a user wearing the wearable electronic device (200) through a first camera (e.g., the first camera (441) of FIG. 4). The processor (450) may correct the acquired images including the eye of the user based on the first correction value and the second correction value, and may perform the gaze tracking function and / or the user authentication function (e.g., an iris authentication function).

[0177] FIG. 16 is a drawing for explaining a method of correcting a display (430) based on the characteristics of a vision correction lens (315) according to one embodiment of the present disclosure.

[0178] Referring to Fig. 16, Fig. 16 <1610> A drawing showing an image (1615) corresponding to a specified pattern (e.g., a specified pattern (730) of FIG. 7) of a cover member (e.g., a cover member (300) of FIG. 3a) acquired through an eye tracking camera (e.g., an eye tracking camera (725) of FIG. 7) when a vision correction lens (e.g., a vision correction lens (315) of FIG. 3b) mounted on a wearable electronic device (e.g., a wearable electronic device (200) of FIG. 2a and FIG. 2b) is for farsightedness (e.g., a convex lens). FIG. 16 <1630> This is a drawing showing an image (1635) corresponding to a specified pattern (730) of a cover member (300) obtained through a gaze tracking camera (725) when a vision correction lens (315) mounted on a wearable electronic device (200) is for myopia (e.g., a concave lens). FIG. 16 <1650> This is a drawing showing an image (1655) corresponding to a specified pattern (730) of a cover member (300) obtained through a gaze tracking camera (725) when a vision correction lens (315) is not mounted on a wearable electronic device (200).

[0179] In one embodiment, when the wearable electronic device (200) is equipped with a farsighted vision correction lens (315) (e.g., a convex lens), the processor (e.g., the processor (450) of FIG. 4) may set the characteristic values ​​of the vision correction lens (315) such that an image (1615) acquired through the gaze tracking camera (725) becomes an image (1655) when the vision correction lens (315) is not equipped. For example, the processor (450) may set the characteristic values ​​of the vision correction lens (315) for at least some areas in which a singularity is detected among a plurality of areas in the image (1615) corresponding to a specified pattern (730) of the cover member (300) to a first characteristic value, and may set the characteristic values ​​of the vision correction lens (315) for at least some other areas in which a singularity is not detected among the plurality of areas in the image (1615) to a second characteristic value (e.g., a second characteristic value different from the first characteristic value).

[0180] In one embodiment, the processor (450) may set the characteristic values ​​of the vision correction lens (315) so that, when the wearable electronic device (200) is equipped with a nearsighted vision correction lens (315) (e.g., a concave lens), the image (1635) acquired through the gaze tracking camera (725) becomes an image (1655) when the vision correction lens (315) is not equipped. For example, the processor (450) may set the characteristic values ​​of the vision correction lens (315) for at least some areas in which a singular point is detected among a plurality of areas in the image (1635) corresponding to the specified pattern (730) of the cover member (300) to a third characteristic value, and may set the characteristic values ​​of the vision correction lens (315) for at least some other areas in which a singular point is not detected among the plurality of areas in the image (1635) to a fourth characteristic value (e.g., a fourth characteristic value different from the third characteristic value).

[0181] FIG. 17 is a drawing for explaining a method of correcting a display (430) based on the characteristics of a vision correction lens (315) according to one embodiment of the present disclosure.

[0182] Referring to FIG. 17, when a wearable electronic device (e.g., the wearable electronic device (200) of FIGS. 2A and 2B) is not equipped with a vision correction lens (e.g., the vision correction lens (315) of FIG. 3B), a processor (e.g., the processor (450) of FIG. 4) may display a first image (1705) acquired through a second camera (e.g., the second camera (443) of FIG. 4) on a display (e.g., the display (430) of FIG. 4). The present invention is not limited thereto, and the processor (450) may also display content (e.g., a virtual image) stored in a memory (e.g., the memory (420) of FIG. 4) as the first image (1705) on the display (450). In this case, the first image (1705) may appear to the user as an image (1720) identical to the first image (1705).

[0183] In one embodiment, when the wearable electronic device (200) is equipped with a vision correction lens (315), the processor (450) may display a second image (1710) acquired through the second camera (443) on the display (430). However, the present invention is not limited thereto, and the processor (450) may also display content (e.g., a virtual image) stored in the memory (420) as the second image (1710) on the display (450). The second image (1710) may appear to the user as an image (1725) different from the first image (1710) (e.g., a distorted image). In order to prevent the user from seeing an image (1725) (e.g., a distorted image) that is different from the first image (1710) when the vision correction lens (315) is mounted, the processor (450) may acquire an image corresponding to a designated pattern (e.g., a designated pattern (730) of FIG. 7) included in a cover member (e.g., a cover member (300) of FIG. 3A) through an eye tracking camera (e.g., an eye tracking camera (725) of FIG. 7) and set a characteristic value of the vision correction lens (315) based on the image. For example, the processor (450) may set a characteristic value of the vision correction lens (315) for at least some areas that do not satisfy a designated condition among a plurality of areas in the image corresponding to the designated pattern (730) as a first characteristic value, and may calculate a first correction value based on the first characteristic value. The processor (450) can set the characteristic value of the vision correction lens (315) for at least some other areas that satisfy a specified condition among a plurality of areas in an image corresponding to a specified pattern (730) to a second characteristic value that is different from the first characteristic value, and can calculate a second correction value based on the second characteristic value. The processor (450) can correct the display (430) based on the calculated first correction value and second correction value, and display a third image (1715) on the corrected display (430).For example, the third image (1715) may have the same form as the first image (1705) (e.g., the first image (1705) without distortion), but may have a distorted form when displayed on a display (430) that has been corrected based on the first correction value and the second correction value that have been calculated. For example, when the third image (1715) is displayed on the corrected display (430) and the user views the third image (1715) through the vision correction lens (315), the third image (1715) may appear in the form of the first image (1705) (e.g., the first image (1705) without distortion) when the vision correction lens (315) is not mounted on the wearable electronic device (200). For example, when a third image (1715) (e.g., an image having a distorted shape) is displayed on a corrected display (430), the third image (1715) can be viewed as an undistorted image (1730) to the user through the vision correction lens (315).

[0184] As described above with reference to FIGS. 5 to 17 according to various embodiments, when the vision correction lens (315) is mounted on the wearable electronic device (200), instead of correcting the display (430) with a predetermined characteristic value set for the vision correction lens (315), an image corresponding to a designated pattern of the cover member (300) is acquired, and based on the acquired image, the characteristic values ​​of the vision correction lens (315) can be set differently for an area where a singularity is detected (e.g., an area that does not satisfy a designated condition) and an area where a singularity is not detected (e.g., an area that satisfies a designated condition). Depending on the optical characteristics (e.g., refractive index and / or magnification) of the vision correction lens (315), an image displayed on the display (430) may be distorted. However, by actively setting the characteristic values ​​of the vision correction lens (315) based on embodiments according to the present disclosure to correct the display (430), a distorted image can be prevented from being displayed on the corrected display (430).
