[0030] Hereinafter, preferred embodiments according to the present invention will be described in detail with reference to the accompanying drawings. The detailed description disclosed below, together with the accompanying drawings, is intended to describe exemplary embodiments of the present invention and is not intended to represent the only embodiment in which the present invention can be practiced. In order to clearly explain the present invention in the drawings, parts unrelated to the description may be omitted, and the same reference numerals may be used for identical or similar components throughout the specification.

[0031] FIG. 1 is a diagram showing the main configuration of an electronic device for measuring eye diseases according to an embodiment of the present invention.

[0032] Referring to FIG. 1, the electronic device (100) according to the present invention may include a communication unit (110), an input unit (120), a camera (130), a display unit (140), a memory (150), and a control unit (160).

[0033] The communication unit (110) can receive an application for measuring eye diseases through communication with an external device (not shown) and can schedule a medical appointment for a user confirmed to have an eye disease through communication with a server (not shown) operated by a medical institution such as an ophthalmology clinic or an optician. To this end, the communication unit (110) communicates with the external device or server via 5G (5 소 It can perform wireless communication such as (generation communication), LTE-A (long term evolution-advanced), LTE, and Wi-Fi (wireless fidelity).

[0034] The input unit (120) generates input data in response to user input of the electronic device (100). To this end, the input unit (120) may include input means such as a keyboard, a key pad, a dome switch, a touch panel, a touch key, a mouse, and a menu button.

[0035] The camera (130) may include a plurality of cameras and may acquire video data including video data and still image data including the user's face. To this end, the camera (130) receives an optical signal and generates image data from the optical signal. The camera may be equipped with a camera sensor and a signal converter. The camera sensor converts the optical signal into an electrical image signal, and the signal converter may convert the analog image signal, which is the electrical image signal, into digital image data.

[0036] The display unit (140) displays display data according to the operation of the electronic device (100). The display unit (140) includes a liquid crystal display (LCD), a light emitting diode (LED) display, an organic light emitting diode (OLED) display, a micro electro mechanical systems (MEMS) display, and an electronic paper display. The display unit (140) can be combined with an input unit (120) to be implemented as a touch screen.

[0037] The memory (150) stores operation programs of the electronic device (100). The memory (150) can store an application that can measure the user's eye disease, and can store an image analysis algorithm that can determine the user's gaze position and gaze distance by analyzing video data of the user's face acquired from the camera (130).

[0038] When the control unit (160) receives an activation signal to activate the application from the input unit (120), it activates the application and activates the camera (130) to obtain video data of the face of the user using the electronic device (100).

[0039] The control unit (160) determines whether position adjustment is necessary for the user's face direction, gaze distance, and gaze position based on the analysis results of video data received from the camera (130). More specifically, the control unit (160) can determine the user's face direction by checking whether the user's face direction is facing the display unit (140) directly through the analysis of video data. To this end, the control unit (160) can identify feature points such as eyebrows, pupils, nose tip, lips, etc. through the analysis of the user's face in the video data, and can determine whether the user is facing the electronic device (100) directly based on the identified feature points.

[0040] In addition, the control unit (160) can determine the distance of sight between the user and the display unit (140) and the position of the user's gaze through the analysis of video data. To this end, the control unit (160) can determine the position of the user's pupils by analyzing the user's face included in the video data.

[0041] Additionally, the control unit (160) can check at least one of the following information: the focal length of the camera (130), the distance between the centers of the user's eyes, the distance between the centers of the user's eyes in video data, and the distance from the focal length to the centers of the user's eyes. The focal length of the camera (130) is determined by the position of the camera sensor, i.e., the lens, and the control unit (160) can obtain it directly from the camera sensor, or indirectly obtain it based on information regarding the position and arrangement of the camera sensor that changes according to the operation of the camera sensor.

[0042] The distance between the centers of the user's eyes may be information stored in memory (150) or information received from an external device. At this time, the distance between the centers of the user's eyes may be determined by the user's age, gender, etc. The distance between the centers of the user's eyes in video data may be calculated based on the position of the user's pupils confirmed in the video data. In addition, the distance information from the focal length to the center of the user's eyes can be calculated using (distance between the centers of the user's eyes: distance from the focal length to the center of the user's eyes = distance between the centers of the user's eyes in video data: camera focal length). The control unit (160) can calculate the distance information between the camera (130) and the user, i.e., the line of sight distance, by adding the distance information from the calculated focal length to the center of the user's eyes and the camera focal length.

[0043] Although not shown, the electronic device (100) may be equipped with a LiDAR sensor capable of measuring distance, and may calculate the line of sight distance from the LiDAR sensor to the user based on the LiDAR sensor.

[0044] Next, if position adjustment is required for the user's face direction, gaze distance, and gaze position, the control unit (160) may display a guideline for the user's face position on the display unit (140). At this time, the guideline may include the direction in which parts of the face are positioned for feature points such as the user's eyebrows, pupils, nose, lips, etc., and the control unit (160) may obtain video data in which the user's face direction, gaze distance, and gaze position have been changed according to the guideline.

[0045] The control unit (160) performs measurement of the user's eye disease using video data acquired from the camera (130). More specifically, after the user's face direction, gaze distance, and gaze position are determined, the control unit (160) can display a measurement screen for measuring the eye disease on the display unit (140) when a measurement signal for measuring the eye disease is received from the input unit (120). In addition, since the user must move their gaze while looking at the display unit (140), a problem may arise where the gaze position confirmed while looking at the camera (130) differs from the gaze position when looking at the eye disease display screen displayed on the display unit (140). Therefore, the control unit (160) can perform correction of the user's gaze position and gaze distance based on the gaze position when the user looks at the camera (130) and when looking at the display unit (140) while the user keeps their face fixed in the same position.

[0046] The control unit (160) displays a screen on the display unit (140) for measuring presbyopia and macular degeneration among the user's eye diseases. In particular, the control unit (160) can sequentially display a plurality of visual targets for measuring presbyopia on the display unit (140).

[0047] The control unit (160) can display multiple measurement screens according to multiple measurement methods used when measuring macular degeneration on the display unit (140). More specifically, the control unit (160) can display a screen for measuring macular degeneration using an Amsler chart and a screen for measuring macular degeneration using an M-type modified chart on the display unit (140) by the user's selection.

[0048] The control unit (160) can display the measurement results of the confirmed eye disease on the display unit (140). In addition, if the control unit (160) confirms that the user's eye disease measurement results require treatment, it can identify a medical institution for treatment based on the eye disease measurement results and provide guidance. At this time, the control unit (160) can identify a medical institution located within a critical distance based on the location of the electronic device (100) or the location entered by the user, and can make a medical appointment for at least one of the medical institutions identified by the user's input.

[0049] FIG. 2 is a flowchart illustrating a method for performing eye disease measurement according to an embodiment of the present invention.

[0050] Referring to FIG. 2, in step 201, the control unit (160) checks whether an activation signal to activate the application is received from the input unit (120). If, as a result of the check in step 201, an activation signal is received, the control unit (160) performs step 203, and if an activation signal is not received, the control unit (160) waits for the reception of an activation signal.

[0051] In step 203, the control unit (160) acquires video data of the face of a user using the electronic device (100). To do this, the control unit (160) can activate the application and activate the camera (130) when an activation signal is received. In step 205, the control unit (160) determines whether position adjustment is necessary for the user's face direction, gaze distance, and gaze position based on the analysis results of the video data received from the camera (130).

[0052] As a result of the verification in step 205, if position adjustment is required, the control unit (160) performs step 207, and if position adjustment is not required, the control unit (160) performs step 209. More specifically, the control unit (160) can determine the direction of the user's face by analyzing video data to determine whether the user's face direction is facing the display unit (140) directly. To this end, the control unit (160) can identify feature points regarding eyebrows, pupils, nose tip, lips, etc. through analysis of the user's face in the video data, and can determine whether the user is facing the electronic device (100) directly based on the identified feature points.

[0053] In addition, the control unit (160) can determine the distance of sight between the user and the display unit (140) and the position of the user's gaze through the analysis of video data. To this end, the control unit (160) can determine the position of the user's pupils by analyzing the user's face included in the video data.

[0054] Next, if position adjustment is required for the user's face direction, gaze distance, and gaze position, the control unit (160) may display a guideline for the user's face position on the display unit (140). At this time, the guideline may include the direction in which parts of the face are positioned for feature points such as the user's eyebrows, pupils, nose, lips, etc., and the control unit (160) may obtain video data in which the user's face direction, gaze distance, and gaze position have been changed according to the guideline.

[0055] In step 209, the control unit (160) performs a measurement of the user's eye disease using video data acquired from the camera (130). This will be explained in more detail using Fig. 3 below.

[0056] Next, in step 211, the control unit (160) can perform step 213 if it is confirmed that the user's eye disease measurement result requires treatment, and can perform step 215 if it is confirmed that treatment is not required. In step 213, the control unit (160) can identify a medical institution for treatment based on the eye disease measurement result and provide guidance. More specifically, if at least one of the eye diseases, such as astigmatism and macular degeneration, is confirmed as a result of the eye disease measurement, the control unit can identify a medical institution related to the disease, such as a hospital or an optician, and provide guidance to the user.

[0057] At this time, the control unit (160) can identify a medical institution located within a critical distance based on the location of the electronic device (100) or the location entered by the user, and can make a medical appointment for at least one of the medical institutions identified by the user's input.

[0058] In step 215, the control unit (160) can terminate the process if it receives a deactivation signal to deactivate the application from the input unit (120), and if no deactivation signal is received, it can return to step 203 and re-perform the operations of steps 203 through 213.

[0059] FIG. 3 is a detailed flowchart illustrating a method for measuring eye diseases according to an embodiment of the present invention.

[0060] Referring to FIG. 3, in step 301, when the user's face direction, gaze distance, and gaze position are determined, the control unit (160) can perform step 303 to display a measurement screen for measuring eye disease on the display unit (140) after receiving a measurement signal from the input unit (120). At this time, the eye disease measurement screen will be explained using FIG. 4 to FIG. 11 below. In addition, since the user must move their gaze while looking at the display unit (140), a problem may arise where the gaze position confirmed while looking at the camera (130) differs from the gaze position when looking at the eye disease display screen displayed on the display unit (140). Therefore, the control unit (160) can perform correction on the user's gaze position and gaze distance based on the gaze position when looking at the camera (130) and when looking at the display unit (140) while the user keeps their face fixed in the same position.

[0061] In addition, the eye disease measurement screen includes a screen for measuring the user's presbyopia and a screen for measuring macular degeneration, wherein the screen for measuring macular degeneration may include a screen for measuring using an Amsler chart and a screen for measuring using an M-type distorted vision.

[0062] In step 305, the control unit (160) can measure the user's eye disease based on the measurement screen. In step 307, the control unit (160) displays the measurement result for the eye disease on the display unit (140) and returns to step 211 of FIG. 2.

[0063] FIGS. 4 and 5 are screen example diagrams for explaining a method for measuring a user's presbyopia according to an embodiment of the present invention.

[0064] Referring to FIGS. 4 and 5, after the control unit (160) activates the eye disease measurement application, if a menu for measuring presbyopia among eye diseases is selected from the input unit (120), the control unit (160) can display a detailed description screen (401) related to measuring presbyopia among eye diseases on the display unit (140) as shown in FIG. 4 (a).

The control unit (160) can continuously measure and display the distance of sight between the camera (130) and the user at the bottom of the second target (503). The control unit (160) can analyze the line of sight confirmed in the first sample (501) and the second sample (503) when an input for the confirmation button (504) is received from the input unit (120).

[0066] The control unit (160) can display the presbyopia measurement result (505) on the display unit (140) as shown in (c) of FIG. 5 based on the result of analyzing the viewing distance. The control unit (160) can also display information about opticians, eyewear fitting sites, etc., where glasses can be fitted based on the presbyopia measurement result, in the advertising area (506) at the bottom of the presbyopia measurement result (505), and can display information about medical institutions, such as ophthalmology clinics, that can measure the presence of presbyopia more accurately and precisely.

[0067] FIG. 6 is an example screen diagram illustrating a method for selecting a method for measuring macular degeneration according to an embodiment of the present invention. FIG. 7 and FIG. 8 are example screen diagrams illustrating a method for measuring a user's macular degeneration using an Amsler chart according to an embodiment of the present invention.

[0068] Referring to FIGS. 6 to 8, after the control unit (160) activates the eye disease measurement application, if a menu for measuring macular degeneration among eye diseases is selected in the input unit (120), the control unit (160) can display a selection screen as shown in FIG. 6 on the display unit (140). At this time, the selection screen may include a selection button (601) for using the Amsler chart among the methods for measuring macular degeneration and a selection button (602) for using the M-type modified chart.

[0070] When the control unit (160) receives input for the confirmation button (704) from the input unit (120) when the viewing distance becomes an appropriate distance, for example, 30 cm, it can display a guide screen for measuring macular degeneration of the left eye while covering the right eye as in FIG. 8 (a) on the display unit (140). When the control unit (160) receives input for the confirmation button (801) from the input unit (120) on the guide screen as in FIG. 8 (a), it can display an Amsler chart on the display unit (140) as in FIG. 8 (b).

[0071] The Amsler chart may display a reference point (802) that serves as a standard for macular degeneration and a position (803) for the user's gaze. At this time, the display unit (140) displays a verification bar (804, 805) for checking the abnormal area based on the reference point (802), and the control unit (160) can check the value when an input occurs on the verification bar (804, 805) by the input unit (120). Subsequently, when an input for the verification button (806) occurs from the input unit (120), the control unit (160) can check the input value through the verification bar (804, 805). Additionally, the control unit (160) can perform a measurement of the right eye once the measurement of the left eye is completed.

[0072] The control unit (160) can display the measurement result (807) regarding whether macular degeneration has been measured, based on the values ​​entered by the confirmation bar (804, 805) when measuring macular degeneration in both eyes, on the display unit (140) as shown in (c) of FIG. 8. The control unit (160) can also display information about medical institutions related to macular degeneration, such as opticians and ophthalmologists, in the advertisement area (808) at the bottom of the measurement result (807) regarding macular degeneration.

[0073] FIGS. 9 to 11 are screen example diagrams for explaining a method of measuring a user's macular degeneration using an M-type deformation according to an embodiment of the present invention.

[0074] Referring to FIGS. 6, 9 to 11, when a signal is input to a selection button (602) for using M-type deformed vision among the methods for measuring macular degeneration as in FIG. 6, the control unit (160) can display a detailed explanation screen (901) for measuring macular degeneration using M-type deformed vision on the display unit (140) as in FIG. 9 (a). When input occurs to a confirmation button (902) displayed on the detailed explanation screen (901) as in FIG. 9 (a), the control unit (160) displays a start screen as in FIG. 9 (b) on the display unit (140). When input occurs to a start button (903) on the start screen displayed on the display unit (140), the control unit (160) can guide and measure the most appropriate line of sight distance between the camera (130) and the user to use M-type deformed vision and display it on the display unit (140) as in FIG. 9 (c).

[0075] When the control unit (160) receives input for the confirmation button (904) from the input unit (120) when the viewing distance becomes an appropriate distance, for example, 30 cm, the control unit (160) can display a guide screen for measuring macular degeneration of the left eye while covering the right eye as in (a) of FIG. 10 on the display unit (140). When the control unit (160) receives input for the confirmation button (1001) from the input unit (120) on the guide screen as in (a) of FIG. 10, the control unit (160) can display an inspection screen (1002) using an M-type modified view as in (b) of FIG. 10 on the display unit (140). At this time, the inspection screen (1002) may be a screen in which a reference center line is displayed horizontally with respect to the display unit (140).

[0076] After the inspection screen (1002) as shown in (b) of FIG. 10 is displayed, if an input is received from the input unit (120) for a selection button (1003) for a straight line or a selection button (1004) for a curved line, the control unit (160) can display an inspection screen (1005) on the display unit (140) in which a reference center line is displayed vertically with respect to the display unit (140) as shown in (c) of FIG. 10. If an input is received from the input unit (120) for a selection button (1006) for a straight line or a selection button (1007) for a curved line, the control unit (160) can complete the measurement of macular degeneration for the left eye based on this.

[0077] And when the measurement of macular degeneration for the right eye is completed in the manner described above, the control unit (160) can display the measurement result (1101) regarding macular degeneration on the display unit (140) as shown in Fig. 11. And the control unit (160) can display information about medical institutions such as opticians and ophthalmologists related to macular degeneration in the advertising area (1102) at the bottom of the measurement result (1101) regarding macular degeneration.

[0078] FIG. 12 is an example screen for determining the severity of macular abnormalities based on weighted area scores according to an embodiment of the present invention.

[0079] The control unit (160) can display an Amsler grid on the display unit (140), and at this time, a score according to weights can be pre-set from the center for an Amsler grid self-diagnosis test.

[0080] As can be seen in Fig. 12(a), a weighted area range (score) can be applied in which a high score (e.g., 10 points) is assigned starting from the center of the Amsler grid test and a low score (e.g., 1 point) is assigned as it moves toward the periphery.

[0081] This is because, from the perspective of visual function, the central part of the macula is the most important; if the center is affected even by a small area, visual impairment is severe, whereas if the affected area is outside the center, the impact may be minimal even if the affected area is large.

[0082] First, the control unit (160) displays the Amsler grid on the display unit (140) and allows the user to directly mark areas where the straight line appears curved or broken. That is, as shown in FIG. 12(b)(c), specific areas can be marked.

[0083] Next, the control unit (160) can quantify the severity of macular abnormality by multiplying the abnormal area in each weighted area and the weighted score of the area indicated by the user, and calculating the weighted area score for the entire abnormal area.

[0084] For the sake of convenience of explanation, the area of ​​the abnormal part in FIG. 12(b) can be assumed to be 1 for point 3, 5 for point 4, 6 for point 5, 6 for point 6, 5 for point 7, and 3 for point 8, and the area of ​​the abnormal part in FIG. 12(c) can be assumed to be 1 for point 4, 2 for point 5, 2 for point 6, 5 for point 7, and 1 for point 8 (the unit of area may vary).

[0085] In this case, the weighted area score of the user corresponding to Fig. 12(b) is 3x1 + 4x5 + 5x6 + 6x6 + 7x5 + 8x3 = 148 points, and the weighted area score of the user corresponding to Fig. 12(c) is 4x1 + 5x2 + 6x2 + 7x5 + 8x1 = 69 points, so the severity of the macular abnormality of the user corresponding to Fig. 12(b) may be high.

[0086] FIG. 13 is a screen example diagram showing a cover that covers a user's eyeball for measuring eye disease according to an embodiment of the present invention.

[0087] Referring to FIGS. 8, FIGS. 10, and FIGS. 13, the control unit (160) can analyze the user's face while the screen of FIG. 8 (a) or FIG. 10 (a) is displayed on the display unit (140) to check whether the user is properly covering their right eye as shown on the display unit (140). To do this, the user can cover their right eye using a cover (1200) as shown in FIG. 13. At this time, the cover (1200) may include a covering portion (1210) and a handle portion (1220). For example, the height of the cover (1200) may be 185 mm, the height of the covering portion (1210) may be 45 mm, and the width of the covering portion (1210) may be 58 mm, but is not necessarily limited thereto.

[0088] When a user covers their right eye using a cover (1200), the control unit (160) can detect the user's left eye and the cover (1200) through the analysis of video data. At this time, if the left eye is identified in the video data and the identification symbol included in the cover (1210) is identified in the video data, the control unit (160) can confirm that the user has properly covered their right eye using the cover (1200). At this time, the identification symbol may be implemented with a width of 23 mm and a height of 4 mm, but is not necessarily limited thereto.

[0089] FIG. 14 is a screen example diagram showing the process of performing a near vision test according to an embodiment of the present invention.

[0090] If the user selects a visual acuity test on the display unit (140) and then selects a near vision test, the drawings shown in FIG. 14 can be displayed on the display unit (140).

[0091] First, the control unit (160) can align the user's face with the box through the camera (130) and adjust the distance by moving the user's face back and forth (Fig. 14(a)). At this time, the distance to the user's face can be adjusted by moving the electronic device (100) directly, or the distance can be adjusted by moving only the user's face while keeping the electronic device (100) in place.

[0092] Additionally, the user may test the right eye or the left eye separately, and the opposite eye that is not being tested may be covered using the aforementioned cover (1200) (Fig. 14(b)).

[0093] Next, the control unit (160) may display a specific number (e.g., 5) in the central part of the display unit (140) and allow the user to select the same shape. As can be seen in FIG. 14(c), the control unit (160) may display a plurality of numbers (e.g., 6, 2, 5) and a question mark at the bottom of the display unit (140) and display a specific number (e.g., 5) in the central part. At this time, the control unit (160) may allow the user to select a number corresponding to the specific number from among the plurality of numbers (repeated several times), and the results of the near vision test of the left eye (or right eye) may be obtained according to the user's selection result.
