The communication module 190 may include one or more communication processors capable of operating independently from the processor 120 (e.g., an application processor (AP)) and supporting direct (e.g., wired) communication or wireless communication. According to an embodiment, the communication module 190 may include a wireless communication module 192 (e.g., a cellular communication module, a short-range wireless communication module, or a global navigation satellite system (GNSS) communication module) or a wired communication module 194 (e.g., a local area network (LAN) communication module or a power line communication (PLC) module). A corresponding one of these communication modules may communicate via a first network 198 (e.g., a short-range communication network such as Bluetooth TM , Wireless Fidelity (Wi-Fi) Direct, or Infrared Data Association (IrDA)) or a second network 199 (for example, a long-distance communication network such as a traditional cellular network, a 5G network, a next-generation communication network, the Internet, or a computer network (for example, a LAN or a wide area network (WAN)))) to communicate with an external electronic device.

[0053] The electronic device 101 may include a processor 120, which includes various processing circuits. The processor 120 may be implemented as one or more integrated circuit (IC) chips and may run various data processing. For example, the processor 120 may be implemented as a system on a chip (SoC). The processor 120 may include subcomponents, which include a central processing unit (CPU), a graphics processing unit (GPU), a neural processing unit (NPU), an image signal processor (ISP), a display controller, a memory controller, a storage controller, an application processor (AP), a communication processor (CP) and / or a sensor interface. The subcomponents are only examples. For example, the processor 120 may also include other subcomponents. For example, some subcomponents may be omitted from the processor 120. According to an embodiment, the processor 120 may include a sensor hub 250. The sensor hub 250 may control the sensor modules (e.g., Figure 1 The sensor hub 250 may include an overall drive of the sensor module 176. For example, the sensor hub 250 may include a display brightness meter. The processor 120 may obtain a lux value from the illuminance sensor. In an embodiment, the processor 120 may send a signal by controlling the distance detection sensor 210 to be described later. The processor 120 may measure the distance by obtaining a signal reflected from the sent signal.

[0054] The electronic device 101 may include a distance detection sensor 210. The distance detection sensor 210 may include a time-of-flight (TOF) sensor. The distance detection sensor 210 is a sensor that measures the environmental distance, and may output the distance by emitting infrared rays (IR) and calculating the time for the light to return. The distance detection sensor 210 may include a light emitting unit and a light receiving unit. The distance detection sensor 210 may include a light emitting unit. The light emitting unit of the distance detection sensor 210 may emit a light source of a specific frequency to detect the distance. The distance detection sensor 210 may include a light receiving unit. The light receiving unit of the distance detection sensor 210 may detect light of a specific frequency. The distance detection sensor 210 may calculate the distance based on the detected light. The distance detection sensor 210 may output the calculated distance. For example, the distance detection sensor 210 may use a wavelength of 940nm (nanometers) or 1400nm. Hereinafter, in the present disclosure, the distance detection sensor 210 is described as including a light emitting unit and a light receiving unit, in other words, including a sending unit and a receiving unit, but the embodiments of the present disclosure are not limited thereto. According to an embodiment, a light emitting unit and a light receiving unit for distance detection may be implemented as separate components.

[0055] The light emitting unit of the distance detection sensor 210 may send a first signal. The light receiving unit of the distance detection sensor 210 may receive a second signal reflected by the first signal. The first signal may correspond to an electromagnetic wave of a specific frequency. The distance detection sensor 210 may output a distance determined based on the second signal reflected back by the first signal. According to an embodiment. The distance detection sensor 210 may be a direct time of flight (DTOF) sensor. The distance detection sensor 210 may send a first signal and receive a second signal reflected by an external object so as to determine the distance to the external object based on the time interval between sending the first signal and receiving the second signal. According to an embodiment, the distance detection sensor 210 may be an indirect time of flight (ITOF) sensor. The distance detection sensor 210 may determine the distance to the external object based on the difference between the phase of the first signal and the phase of the second signal.

[0056] Hereinafter, in the present disclosure, as an example, a TOF sensor is shown as the distance detection sensor 210, but the description of the distance detection sensor 210 may be substantially the same as another type of sensor that performs the same function as the TOF sensor. For example, the distance detection sensor may be a depth sensor. For example, the depth sensor may be a laser detection and ranging (LiDAR) sensor. For example, the depth sensor may be a radar sensor.

[0057] The electronic device 101 may include at least one camera 220 (eg, Figure 1 The at least one camera 220 may include at least one of a wide-angle camera, an ultra-wide-angle camera, a first telephoto camera, or a second telephoto camera. The wide-angle camera may be used to obtain an image of an object at a specific distance (e.g., 28 cm (centimeter) or more) from the electronic device 101 at a low magnification (e.g., less than 3 times magnification). The ultra-wide-angle camera may be used to obtain an image of an object at a lower distance from the electronic device 101 at a low magnification. The first telephoto camera may be used to obtain an image of an object within a first magnification range (e.g., greater than or equal to 3 times magnification and less than 10 times magnification). The second telephoto camera may be used to obtain an image of an object within a second magnification range (e.g., greater than or equal to 10 times magnification and less than 15 times magnification).

[0058] The electronic device 101 may include a display 230 (eg, Figure 1 The display module 160 of the distance detection sensor 210 may be provided. The display 230 may visually provide information to the user. The display 230 may display a user interface (UI) about an application running in the processor 120 under the control of the processor 120. According to an embodiment, the display 230 may display status information related to the calibration of the distance detection sensor 210.

[0059] The user may perform self-repair of the electronic device 101. The electronic device 101 may support functions related to self-repair. After self-repair, the sensor (e.g., the distance detection sensor 210) of the electronic device 101 may need to be calibrated. However, if the housing (e.g., the rear glass) of the electronic device 101 is not assembled normally or there are obstacles near the sensor (e.g., the distance detection sensor 210), it is difficult to perform calibration normally. For example, in the case of performing an incorrect calibration, the electronic device 101 may determine that there is an object in front of the sensor even if there are no obstacles in front of the sensor. For example, the electronic device 101 may identify the camera to be used in at least one camera 220 based on the output result of the distance detection sensor 210. The failure of the distance detection sensor 210 may cause unnecessary camera switching. For example, even if the object is not adjacent to the distance detection sensor 210, the electronic device 101 may switch the camera to an ultra-wide-angle camera. In other words, unnecessary camera switching may occur due to the incorrect determination of the distance detection sensor 210. Therefore, according to the present disclosure, the electronic device 101 may include a method for providing a user with status information obtained from a calibration process performed after self-repair, so as to reduce the influence caused by calibration errors of sensors.

[0060] According to an embodiment, when a user repairs an electronic device by himself, the electronic device 101 may provide appropriate information for each step for normal repair and evaluation. The electronic device 101 may provide appropriate guidance to the user. Even without professional knowledge, the user can identify and check environmental conditions, the status of the electronic device, etc. According to an embodiment. The electronic device 101 may provide the user with a notification about the assembly status of the housing (e.g., rear glass) of the electronic device 101 through a user interface (UI) or a voice signal. In addition, according to an embodiment, the electronic device 101 may provide the user with a UI or a voice signal to control environmental factors (e.g., sensor communication, environment, adjacent objects) that may occur during the calibration process.

[0061] Figure 3 is a diagram showing an example of a distance detection sensor of an electronic device according to various embodiments. Figure 1 The electronic device 101 may include a main body and a housing connected to the main body. For example, in addition, the distance detection sensor (for example, Figure 2 The distance detection sensor 210 of the electronic device 101 may be configured to obtain the distance to an object in a specific direction (eg, behind). Figure 2 At least one camera 220) may be configured to obtain an image of an object in a specific direction (eg, rearward).

[0062] Reference Figure 3, the repair of the electronic device 101 can be performed while removing the housing 300. After the repair, in order to use the electronic device 101, the housing 300 of the electronic device 101 needs to be assembled. The housing 300 may be connected to the body of the electronic device 101. According to an embodiment, the housing 300 may include a rear glass. In this case, the housing 300 may be arranged so that the signal direction of the distance detection sensor 210 passes through one surface of the housing 300. The housing 300 may be arranged so that the shooting direction of the at least one camera 220 passes through the one surface of the housing 300.

[0063] A partial area of ​​the housing 300 of the electronic device 101 may include a window 310. The window 310 may be formed along the one surface of the housing 300. The window 310 may be disposed so that the signal direction of the distance detection sensor 210 passes through the window 310. The window 310 may be disposed so that the shooting direction of the at least one camera 220 passes through the window 310. The window 310 may be made of a permeable (e.g., transmissive) material so that the signal transmitted from the distance detection sensor 210 is not blocked by the housing 300. For example, the window 310 may be made of a glass material.

[0064] The distance detection sensor 210 may include a light emitting unit (e.g., including a light emitting part and a circuit) 330 and a light receiving unit (e.g., including a light receiving part and a circuit) 340. The distance detection sensor 210 may include a light emitting unit 330. The distance detection sensor 210 may send a first signal through the light emitting unit 330. The first signal may include light corresponding to a specific frequency. The distance detection sensor 210 may include a light receiving unit 340. The distance detection sensor 210 may receive a second signal reflected by the first signal through the light receiving unit 340. The first signal may be reflected by the window 310. After the assembly of the electronic device 101 is completed, the housing 300 may be fixed. Therefore, the position of the window 310 may be fixed. The positional relationship of the window 310 relative to the distance detection sensor 210 is fixed. Therefore, in response to the first signal of the distance detection sensor 210, the pattern of the signal reflected from the window 310 may be fixed. According to an embodiment, the electronic device 101 may detect the crosstalk of the window 310 by the pattern of the signal reflected from the window 310.

[0065] Figure 4a is a diagram showing an example of a measurement result of a distance detection sensor according to various embodiments. Figure 2The distance detection sensor 210 may include a plurality of distance zones. For example, the distance detection sensor 210 may include 64 distance zones. In one distance zone, the light receiving unit (e.g., the light receiving unit 340) may receive a second signal reflected by a first signal emitted by a light emitting unit (e.g., the light emitting unit 330). The distance detection sensor 210 may measure the second signals received in the plurality of distance zones of the light receiving unit.

[0066] Reference Figure 4a , the histogram 400 represents the single photon avalanche diode (SPAD) count (e.g., the number of SPADs) of the distance detection sensor 210 at each time. The horizontal axis 401 of the histogram 400 represents time, and the vertical axis 402 of the histogram 400 represents the SPAD count (unit: kilo counts per second (KCPS)). Since the SPAD count represents the number of photons of the reflected signal, it can refer to, for example, the intensity of the reflected signal.

[0067] The bin 410 represents a housing (e.g., Figure 3 The window of the housing 300 (eg, Figure 3 Bin 420 represents the SPAD count of the signal reflected by the window 310 of the distance detection sensor 210). Bin 420 represents the SPAD count of the signal reflected by the external object (for example, an object located at a distance of 15 cm). Since the distance between the distance detection sensor 210 and the window 310 is shorter than the distance between the distance detection sensor 210 and the external object, the light receiving unit of the distance detection sensor 210 may receive the signal reflected from the window 310 before receiving the signal reflected from the external object. Bin 410 may precede bin 420 in time. In addition, since the window 310 is constructed using a material (for example, glass) for passing the signal, the reflection effect is relatively lower than the reflection effect of the external object. Therefore, the SPAD count in bin 410 is lower than the SPAD count in bin 420.

[0068] After the assembly of the electronic device 101 is completed, since the housing 300 and the window 310 may be fixed, the reception pattern of the signal reflected from the window 310 in response to the first signal of the distance detection sensor 210 may be fixed. According to an embodiment, the distance detection sensor 210 may identify a specific type of crosstalk within a specific time range. The distance detection sensor 210 may identify that the assembly of the housing 300 is normal by identifying a bin (e.g., bin 410) detected within a specific time range.

[0069] Figure 4b is a diagram showing an example of a measurement result of a distance detection sensor according to various embodiments. Figure 2The distance detection sensor 210 may include a plurality of distance zones. For example, the distance detection sensor 210 may include 64 distance zones. In one distance zone, the light receiving unit (e.g., the light receiving unit 340) may receive a second signal reflected by a first signal emitted by a light emitting unit (e.g., the light emitting unit 330). The distance detection sensor 210 may measure the second signals received in the plurality of distance zones of the light receiving unit.

[0070] Reference Figure 4b The histogram 450 represents the SPAD counts of the distance detection sensor 210 at each time. The abscissa axis 451 of the histogram 450 represents time, and the ordinate axis 452 of the histogram 450 represents the SPAD counts (unit: KCPS).

[0071] Bin 460 represents the SPAD count of the signal reflected by the first external object (e.g., an object located at a distance of 10 cm). Bin 470 represents the SPAD count of the signal reflected by the second external object (e.g., an object located at a distance of 15 cm). The first external object may be closer to the distance detection sensor 210 of the electronic device 101 than the second external object. Therefore, the light receiving unit of the distance detection sensor 210 may receive the signal reflected from the first external object before receiving the signal reflected from the second external object. Bin 460 may precede bin 470 in time.

[0072] Since the first external object is generally configured with a material different from the material of the window 310 through which the signal passes, a relatively large amount of the signal may be reflected. In addition, in the window 310 of the histogram 400, the intensity of the light received by the light receiving unit of the distance detection sensor 210 is relatively small. Comparing the histogram 400 with the histogram 450, it can be detected that the SPAD count in the bin 460 may be greater than the SPAD count in the bin 410. According to an embodiment, the distance detection sensor 210 may distinguish whether the measurement result is the crosstalk of the window 310 or the reflection pattern of the adjacent external object based on the SPAD count. The distance detection sensor 210 can identify that the assembly of the housing 310 is normal by identifying a bin (e.g., bin 410) whose SPAD count is less than or equal to a threshold value within a specific time range.

[0073] Figure 5 is a diagram showing an example of crosstalk of a distance detection sensor according to various embodiments. Figure 2The distance detection sensor 210 may include a plurality of distance zones. For example, the distance detection sensor 210 may include 64 distance zones. In one distance zone, the light receiving unit (e.g., the light receiving unit 340) may receive a second signal reflected by a first signal emitted by a light emitting unit (e.g., the light emitting unit 330). The distance detection sensor 210 may measure the second signals received in the plurality of distance zones of the light receiving unit.

[0074] Reference Figure 5 , the window 310 may be set to have a specific air gap with the distance detection sensor 210. After the assembly of the electronic device 101 is completed, the housing 300 may be fixed. Therefore, the position of the window 310 may be fixed. Therefore, the crosstalk of the window 310 may be concentrated at a specific position.

[0075] The distance detection sensor 210 may include a light emitting unit 330 and a light receiving unit 340. The distance detection sensor 210 may include a light emitting unit 330. The distance detection sensor 210 may transmit a first signal through the light emitting unit 330. The distance detection sensor 210 may include a light receiving unit 340. The distance detection sensor 210 may receive a second signal reflected from the window 310 by the first signal through the light receiving unit 340. The light receiving unit 340 of the distance detection sensor 210 may include a plurality of distance regions 540. For example, the number of the plurality of distance regions 540 may be 64. In one distance region, the light receiving unit 340 may receive a second signal reflected by the first signal emitted by the light emitting unit 330. For example, the measurement results in the plurality of distance regions 540 are shown in the following table.

[0076] Table 1

[0077] 79 72 67 67 57 53 49 45 88 81 72 65 60 56 54 50 95 84 75 68 63 59 56 55 100 88 78 71 65 60 59 58 100 89 78 71 67 62 61 60 102 89 80 74 67 64 62 62 98 88 80 72 66 63 60 59 91 84 76 71 65 60 57 56

[0078] The measurement results of Table 1 above have different aspects from the measurement results of the signal reflected only from the external object at a position separated by an air gap distance. For example, the measurement results of the reflected signal of the first external object located at a distance of about 1 cm are as follows.

[0079] Table 2

[0080]

[0081]

[0082] Furthermore, for example, the measurement result of the reflected signal of the second external object located at a distance of about 15 cm is as follows.

[0083] Table 3

[0084] 895 1172 1492 1384 1417 1334 1113 638 1398 1539 1605 1589 1498 1432 1596 1199 1517 1440 1651 1621 1684 1595 1762 1447 1610 1562 1875 2146 2119 1783 1725 1600 1594 1534 1902 2163 2081 1659 1599 1530 1502 1436 1701 1831 1869 1646 1722 1547 1286 1416 1574 1537 1494 1565 1527 1273 999 1356 1612 1534 152 1684 1442 1035

[0085] Referring to Tables 1, 2, and 3, it is confirmed that the intensity of the signal reflected from the window 310 is relatively smaller than the intensity of the signal reflected from the external object (e.g., the first external object, the second external object). This is because the window 310 is configured with a material (e.g., glass) that is easier to pass than the external object. In addition, referring to Tables 2 and 3, it is confirmed that the intensity of the signal reflected from the external object at a near position (e.g., the first external object at about 1 cm from the distance detection sensor 210) is greater than the intensity of the signal reflected from the external object at a far position (e.g., the second external object at about 15 cm from the distance detection sensor 210). This is because the closer the signal is reflected, the smaller the propagation loss. Referring to Table 1, among the 64 distance areas, the distance areas with high intensity (e.g., 100, 100, 88, and 89) are located in the middle area on the left. Referring to Table 2, among the 64 distance areas, the distance areas with high intensity (e.g., 49542, 50992, 43768, and 43018) are located in the middle area on the left. In other words, when an external object is located very close, the shape of the measured crosstalk may be similar to the shape of the crosstalk of the window 310. However, when the intensity measured in each distance region is compared, the intensity of the crosstalk of the window 310 is much smaller than the intensity of the reflected signal of the external object.

[0086] Referring to Table 3, among the 64 distance regions, the distance region with high intensity (e.g., 100, 100, 88, and 89) is located in the middle region. Although the distance between the light emitting unit 330 and the light receiving unit 340 is only 4 mm, the distance between the distance detection sensor 210 and the external object is 15 cm, and therefore, the reflected and entering light relatively more strongly enters the middle of the distance detection sensor 210. The light detected on the side surface of the distance detection sensor 210 may be relatively weak.

[0087] If it is before the housing 300 is connected to the main body of the electronic device 101, the crosstalk value of the distance detection sensor 210 can be basically measured to be close to 0. Since there is no housing 300, the reflection of the window 310 will not occur. If there is no housing 300, a peak value in each distance area of ​​the distance detection sensor 210, that is, a very low value (e.g., 0-10) can also be measured. Therefore, the measurement result in the state where the housing 300 is not assembled may be different from the measurement result of the reflection from the window 310 (e.g., Table 1), the measurement result of the reflection from the first external object (e.g., an external object at about 1 cm from the distance detection sensor 210) (Table 2), and the measurement result of the reflection from the second external object (e.g., an external object at about 15 cm from the distance detection sensor 210) (Table 3).

[0088] Although the housing 300 is assembled to the body of the electronic device 101, it is still possible to detect that the crosstalk is equal to or greater than the threshold. According to an embodiment, the electronic device 101 may identify the presence of foreign matter based on detecting that the crosstalk is equal to or greater than the threshold through the distance detection sensor 210. In addition, the measurement result of the distance detection sensor 210 may have a high-intensity pattern in a portion that is not close to the light emitting unit of the distance detection sensor 210 (for example, a sensor located in the middle area of ​​Table 3). According to an embodiment, if possible, the electronic device 101 may identify the presence of foreign matter based on detecting a high-intensity signal in a distance area of ​​the sensor of the distance detection sensor 210 that is not close to the light emitting unit of the distance detection sensor 210.

[0089] like Figure 3 , Figure 4a , Figure 4b , Figure 5 As shown in the above description, the electronic device 101 according to the embodiment may obtain the state information of the housing 300 of the electronic device 101 based on the measurement result of the signal received from the distance detection sensor 210. According to the embodiment, the electronic device 101 may identify whether the housing 300 is assembled. According to the embodiment, the electronic device 101 may identify whether the housing 300 is normally assembled to the body of the electronic device 101. According to the embodiment, the electronic device 101 may identify whether there is an obstacle in front of the distance detection sensor 210. Based on the measurement result, the electronic device 101 may identify whether the user has normally reassembled the housing 300 after self-repair.

[0090] By providing the user with status information about the assembly of the housing 300 (or the window 310), the electronic device 101 can be calibrated and the user can check the status of the electronic device 101. Hereinafter, the operation of the electronic device 101 providing the user with status information based on the measurement result of the distance detection sensor 210 will be described in more detail.

[0091] Figure 6 1 is a flowchart illustrating an example operation of an electronic device for identifying a properly assembled housing according to various embodiments. Figure 3 The housing 300 of the electronic device 101 can be connected to the main body of the electronic device 101. The electronic device 101 can recognize whether the housing 300 is properly assembled. The processor (for example, Figure 2 The processor 120 of the electronic device (for example, Figure 1 operation of the electronic device 101).

[0092] Reference Figure 6 In operation 601, the electronic device 101 may detect the distance through a distance detection sensor (eg, Figure 2The electronic device 101 may send the first signal through the light emitting unit of the distance detection sensor 210. The first signal may correspond to light of a specific frequency.

[0093] In operation 603, the electronic device 101 may measure the reflected second signal. When the first signal is reflected from the object, the second signal may be received by the light receiving unit of the distance detection sensor 210. According to an embodiment, the electronic device 101 may receive the second signal within a specific time after sending the first signal. Since the distance between the window 310 and the distance detection sensor 210 corresponds to the air gap between the distance detection sensor 210 and the housing 300, it is shorter than the distance to a general external object. Therefore, the signal generated due to the reflection from the window 310 is likely to be received within a specific time from the sending time point of the first signal. Therefore, the electronic device 101 may receive the second signal within a specific time after sending the first signal. The electronic device 101 may receive the second signal received by the housing (e.g. Figure 3 The electronic device 101 may measure the strength of the received second signal.

[0094] In operation 605 , the electronic device 101 may identify whether crosstalk of the window 310 is detected.

[0095] The electronic device 101 may obtain the intensity value of the second signal measured in each of the distance zones through the light receiving unit (eg, light receiving unit 340) of the distance detection sensor 210. The electronic device 101 may identify whether the crosstalk of the window 310 is detected based on the intensity values ​​of the distance zones.

[0096] According to an embodiment, the electronic device 101 may identify whether crosstalk of the window 310 is detected based on the distribution of the intensity values ​​of the distance region. If the distribution has the following trend: the intensity value of the distance region close to the light emitting unit (e.g., the light emitting unit 330) is greater than the intensity value of the distance region far from the light emitting unit 330, the electronic device may recognize that the reflective object is adjacent to the distance detection sensor 210.

[0097] According to an embodiment, the electronic device 101 may identify whether the crosstalk of the window 310 is detected based on whether the intensity values ​​of each of the distance regions are all less than a threshold value. If the intensity values ​​of each of the distance regions are less than the threshold value, the electronic device 101 may identify that the first signal transmitted from the distance detection sensor 210 is reflected by the window 310 instead of being reflected by an external object, or may identify a state in which the housing 300 is not assembled to the body.

[0098] For example, if the reflective object is adjacent to the distance detection sensor 210 and the intensity values ​​of each of the distance regions are all less than the threshold, the electronic device 101 may recognize that the received second signal is reflected by the window 310. The electronic device 101 may recognize that the crosstalk of the window 310 is detected according to the measurement result of the distance detection sensor 210.

[0099] For example, although the reflective object is adjacent to the distance detection sensor 210, the intensity values ​​of each of the distance regions may not all be less than the threshold value. In this case, the electronic device 101 may recognize that an external object located at an adjacent distance (e.g., about 1 cm) is detected based on the measurement result of the distance detection sensor 210. In other words, the electronic device 101 may recognize that the crosstalk of the window 310 is not detected. In addition, for example, if the reflective object is not adjacent to the distance detection sensor 210, the electronic device 101 may recognize that an external object located at an adjacent distance (e.g., about 15 cm) is detected based on the measurement result of the distance detection sensor 210. In other words, the electronic device 101 may recognize that the crosstalk of the window 310 is not detected.

[0100] In the case where the crosstalk of the window 310 is detected, the electronic device 101 may perform operation 607. In the case where the crosstalk of the window 310 is not detected, the electronic device 101 may perform operation 609.

[0101] In operation 607, the electronic device 101 may recognize normal assembly. Here, normal assembly may refer to, for example, that the assembly between the housing 300 of the electronic device 101 and the main body of the electronic device 101 is normal. For example, a user may separate the housing 300 of the electronic device 101 from the main body of the electronic device 101 and may perform self-repair. Afterwards, the housing 300 may be reassembled to the main body by the user. In response to the reassembly, calibration of a sensor (e.g., the distance detection sensor 210) may be required.

[0102] When the assembly is completed, the relative positional relationship between the housing 300 and the distance detection sensor 210 provided on the main body of the electronic device 101 is fixed. Therefore, the crosstalk of the window 310 measured by the distance detection sensor 210 may occur within the expected range. For example, due to the crosstalk of the window 310, the intensity value of each distance area of ​​the distance detection sensor 210 may be less than the threshold value. Due to the crosstalk of the window 310, the intensity value of the distance area adjacent to the light emitting unit may have a higher intensity distribution than the intensity values ​​of other distance areas. Therefore, when the crosstalk of the window 310 is detected, the electronic device 101 can recognize that the housing 300 is assembled normally.

[0103] In operation 609, the electronic device 101 may identify abnormal assembly. The relative positional relationship between the distance detection sensor 210 and the housing 300 is fixed. In this case, the abnormal assembly may refer to, for example, that the relative positional relationship between the distance detection sensor 210 and the housing 300 in the first state is different from the positional relationship between the distance detection sensor 210 and the housing 300 in the second state. The first state may refer to the state of the electronic device 101 after the housing 300 is reassembled according to the self-repair. The second state may refer to the state of the electronic device 101 before the self-repair when the housing 300 and the main body are connected.

[0104] The electronic device 101 may identify abnormal assembly based on the measurement result of the distance detection sensor 210. The electronic device 101 may identify abnormal assembly based on the crosstalk of the window 310 not being detected. According to an embodiment, the electronic device 101 may identify that a foreign object exists between the housing 300 and the distance detection sensor 210 based on the measurement result of the distance detection sensor 210. In addition, according to an embodiment, the electronic device 101 may identify that an external object is located in the distance detection sensor 210 based on the measurement result of the distance detection sensor 210. In addition, according to an embodiment, the electronic device 101 may identify that the housing 300 is not assembled based on the measurement result of the distance detection sensor 210.

[0105] Although not in Figure 6 As shown in FIG. 1 , according to an embodiment, the electronic device 101 may provide a user with a notification indicating the assembly state of the housing 300. For example, the electronic device 101 may provide a notification indicating the assembly state of the housing 300 via a display (eg, Figure 2 The electronic device 101 may output a sound signal notifying the assembly state of the housing 300, for example. The notification may indicate normal assembly, non-assembly, or the presence of an external object. In addition, for example, the electronic device 101 may output a vibration indicating the assembly state of the housing 300. In addition, for example, the electronic device 101 may output an indication of the assembly state of the housing 300 by means of a device (e.g., a light). The color of the light may indicate the assembly state. For example, a red light may indicate that the housing 300 has not been assembled. For example, a yellow light may indicate that the housing 300 is twisted and assembled.

[0106] Figure 7 1 is a flowchart illustrating an example operation of an electronic device for identifying a normal light source environment according to various embodiments. Figure 3 The housing 300 of the electronic device 101 may be connected to the main body of the electronic device 101. The electronic device 101 may recognize whether the housing 300 is properly assembled. Figure 2 The processor 120 of the electronic device (for example, Figure 1operation of the electronic device 101).

[0107] Reference Figure 7 , in operation 701, the electronic device 101 may obtain an environmental value. The electronic device 101 may obtain an environmental value through a light receiving unit (e.g., light receiving unit 340) of the distance detection sensor 210. The environmental value may refer to, for example, the detection intensity of received infrared rays. A user may perform calibration of a sensor (e.g., distance detection sensor 210) of the electronic device 101. The signal sent from the distance detection sensor 210 may be IR. In this case, if a light source including sunlight or IR is near the electronic device 101, it is difficult to perform calibration of the distance detection sensor 210 normally. The electronic device 101 may measure a noise level in order to identify whether it is a normal environment for calibration. The electronic device 101 may obtain an environmental value corresponding to the noise level.

[0108] In operation 703, the electronic device 101 may identify whether the environmental value is less than a threshold value. The threshold value may be used to determine whether the environmental value is less than a threshold value. Figure 3 Whether the signal received by the light receiving unit 340 of the distance detection sensor 210 is Figure 3 The signal intensity of the external IR light source may be stronger than the reflected signal intensity. For example, in the absence of an external IR light source, the measured values ​​in the distance area of ​​the distance detection sensor 210 may be as shown in the following table.

[0109] Table 4

[0110] 2 1 2 1 2 0 0 0 2 3 2 0 4 4 5 0 0 0 1 2 0 5 2 1 0 0 2 0 0 5 2 0 0 0 5 1 0 4 5 1 0 1 1 0 3 1 0 1 0 0 7 3 0 2 0 3 4 1 1 5 2 1 3 2

[0111] In addition, for example, in the case where an external IR light source exists, the measurement value in the distance area of ​​the distance detection sensor 210 may be as shown in the following table.

[0112] Table 5

[0113]

[0114]

[0115] Depending on the presence or absence of an external IR light source, the size of the environmental value in the distance area of ​​the distance detection sensor 210 may change. When the environmental value is less than the threshold value, the electronic device 101 may perform operation 705. When the environmental value is not less than the threshold value, the electronic device 101 may perform operation 707. In operation 705, the electronic device 101 may identify a normal light source environment. The normal light source environment may refer to, for example, a normal condition for performing calibration of the distance detection sensor 210. The distance detection sensor 210 may measure the distance by emitting a signal of a specific frequency (such as IR) and measuring a signal reflected by the signal. Therefore, if there are few factors affecting the specific frequency, the electronic device 101 may identify a normal light source environment.

[0116] In operation 707, the electronic device 101 may identify an abnormal light source environment. In a case where the environment value is not less than the threshold value, in other words, in a case where the environment value is equal to or greater than the threshold value, the electronic device 101 may determine that a light source including sunlight or IR is near the electronic device 101. In a case where it is determined that a light source including sunlight or IR is near the electronic device 101, the electronic device 101 may recognize that it is not a normal environment for calibration.

[0117] Although not in Figure 7 As shown in FIG. 1 , according to an embodiment, the electronic device 101 may provide a user with a notification about a normal light source environment or an abnormal light source environment. For example, the electronic device 101 may provide a user with a notification about a normal light source environment or an abnormal light source environment through a display (e.g., Figure 2 The electronic device 101 may output a sound signal for notifying an abnormal light environment. In addition, for example, the electronic device 101 may output a vibration indicating an abnormal light environment of the housing 300. In addition, for example, the electronic device 101 may output an indication of an abnormal light environment of the housing 300 through a device (e.g., a lamp). In addition, according to an embodiment, the electronic device 101 may provide a message, a sound signal, a notification, or a vibration to guide the user to perform calibration after moving to another place, rather than just notifying the abnormal light environment. Alternatively, according to an embodiment, in addition to notifying the abnormal light environment, the electronic device 101 may also provide a message, a sound signal, a notification, or a vibration to guide the user to perform calibration after moving to another place.

[0118] Figure 8 1 is a diagram showing an example of a user interface (UI) for an application for calibration status check according to various embodiments. The calibration status check may refer to, for example, a sensor (e.g., Figure 2The process of calibration of the distance detection sensor 210 of the electronic device 101 is described. The application for calibration status check may be executed by the processor (eg, the processor 120) of the electronic device 101. The processor 120 may display a UI about the application through a display (eg, the display 230).

[0119] Reference Figure 8 , in state 810, the electronic device 101 may display a guidance screen. When calibration is performed after the user's self-repair, in order to avoid performing an erroneous calibration according to the assembly state and / or reduce an erroneous calibration performed according to the assembly state, the electronic device 101 may provide the user with the surrounding environment and / or the internal physical state of the electronic device 101 to perform calibration. The electronic device 101 may display a guidance screen notifying a test environment suitable for the status check before the calibration status check. The guidance screen may include a message for guiding the following environment: the result of the user's calibration status check is output normally. For example, the guidance screen may include a phrase: "Before performing calibration, you must ensure that there are no obstacles within 1.2M. In addition, please stay away from IR light sources."

[0120] After displaying the guide screen, the electronic device 101 may display a screen for starting the calibration status check. For example, the electronic device 101 may change the state 810 to the state 820 after a certain period of time has passed. For another example, the electronic device 101 may change the state 810 to the state 820 in response to receiving a user input for proceeding to the next step.

[0121] In state 820, the electronic device 101 may display a start screen. In state 830, the electronic device 101 may display a button object for calibration status check. The electronic device 101 may change state 820 to state 830 in response to receiving a user input. For example, the electronic device 101 may receive a touch input of a button object. The electronic device 101 may change state 820 to state 830 in response to the touch input. For another example, the electronic device 101 may change state 820 to state 830 after a specific period of time has passed.

[0122] The start of calibration may be provided to the user by various methods. According to an embodiment, a light emitting diode (LED) light indicating the start of the calibration status check may be displayed. The user may know that the calibration status check has started through the LED light of the electronic device 101. In addition, according to an embodiment, the start of calibration may be provided to the user through a beep. The user may know the start of calibration by listening to the beep.

[0123] In state 830, the electronic device 101 may display an inspection screen. In state 830, the electronic device 101 may display one or more inspection items. For example, the one or more inspection items may include four inspection items: inspection item 841, inspection item 842, inspection item 843, and inspection item 844. According to an embodiment, the electronic device 101 may perform all of the one or more inspection items based on receiving user input in state 820. For example, the electronic device 101 may sequentially perform an inspection operation corresponding to each of the inspection items 841, inspection item 842, inspection item 843, and inspection item 844. As another example, the electronic device 101 may perform an inspection operation corresponding to at least two of the inspection items 841, inspection item 842, inspection item 843, and inspection item 844 in parallel. In addition, according to an embodiment, the electronic device 101 may perform an inspection operation corresponding to a specific inspection item based on receiving an additional input (e.g., a user's touch input) for a specific inspection item that is different from the user input received in state 820.

[0124] According to an embodiment, the electronic device 101 may display an inspection item 841 related to connector assembly. The inspection item 841 may display an inspection result about the connector assembly. The electronic device 101 may identify whether the connector connecting the distance detection sensor 210 to the flexible printed circuit board (FPCB) or the printed board assembly (PBA) is assembled normally. The electronic device 101 may identify whether the connector to the distance detection sensor 210 is normally connected by identifying whether the communication state of the distance detection sensor 210 is normal. In a normal communication state, the processor 120 of the electronic device 101 may receive a signal from the distance detection sensor 210 through a communication interface (e.g., a serial peripheral interface (SPI)) or may send a signal to the distance detection sensor 210.

[0125] According to an embodiment, the electronic device 101 may display a check item 842 related to the IR environment. The check item 842 may display a check result regarding the IR environment. The electronic device 101 may identify whether the electronic device 101 is currently located in a normal light source environment by measuring the environment value. For the operation of the electronic device 101 checking the IR environment, please refer to Figure 7 Description.

[0126] According to an embodiment, the electronic device 101 may display a check item 843 related to an obstacle. The check item 843 may display a result of whether an obstacle is located around the distance detection sensor 210. The electronic device 101 may identify the distance to the external object by measuring a signal reflected by a light emitting unit (e.g., light emitting unit 330) of the distance detection sensor 210. The electronic device 101 may identify whether an obstacle is located around the distance detection sensor 210 based on the distance to the external object and the intensity distribution of the distance area in the light receiving unit (e.g., light receiving unit 340).

[0127] According to an embodiment, the electronic device 101 may display an inspection item 844 related to the housing 300 (e.g., the rear glass). The inspection item 844 may display an inspection result regarding the assembly state of the housing 300. The electronic device 101 may detect the assembly state of the housing 300 by measuring a signal reflected by a signal of a light emitting unit (e.g., the light emitting unit 330) of the distance detection sensor 210. The housing 300 may include a window (e.g., window 310) for the distance detection sensor 210. After the housing 300 is assembled to the main body of the electronic device 101, the positional relationship between the window 310 and the distance detection sensor 210 is fixed. Therefore, the measurement result of the signal reflected from the window 310 may have a specific pattern. For the operation of the electronic device 101 to inspect the assembly state of the housing 300, reference may be made to Figure 6 Description.

[0128] exist Figure 8 In the example, the state of displaying four inspection items (inspection item 841, inspection item 842, inspection item 843, and inspection item 844) on one screen is taken as an example, but the embodiments of the present disclosure are not limited thereto. According to an embodiment, the electronic device 101 may not perform all of the inspection operations corresponding to the four inspection items, but may only perform some of the inspection operations. Optionally, according to an embodiment, in addition to performing the four inspection items, the electronic device 101 may also perform additional inspection operations.

[0129] According to an embodiment, the electronic device 101 may display only some of the check items instead of displaying all of the check items to be performed. For example, after the calibration status check, the electronic device 101 may display only the check items indicating a negative check result on the screen. In addition, for example, after the calibration status check, the electronic device 101 may display the result of one of the check items indicating a negative check result on the screen.

[0130] Although not in Figure 8 As shown in FIG. 1 , the electronic device 101 may provide the user with the result of the inspection item. For example, the electronic device 101 may display the result of the inspection item (eg, Figure 2The electronic device 101 may output a sound signal for notifying the result of the inspection item. In addition, for example, the electronic device 101 may output a vibration for notifying the result of the inspection item. In addition, for example, the electronic device 101 may output a notification for notifying the result of the inspection item by means of a device (e.g., a light). In addition, according to an embodiment, the electronic device 101 may provide a message, a sound signal, a vibration, or a notification to the user to guide the next operation, rather than just notifying the result of the inspection item. According to an embodiment, in addition to notifying the result of the inspection item, the electronic device 101 may also provide a message or a sound signal to the user to guide the next operation. For example, the message or sound signal displayed on the display may include the following phrases.

[0131] 1. "After reassembling the rear glass, perform calibration."

[0132] 2. "Clear any obstructions in front of the unit and perform calibration."

[0133] 3. "Go to an environment without external light sources and perform calibration".

[0134] 4. "Since the rear glass is not detected, perform calibration after assembling the rear glass."

[0135] In the following, reference will be made to Figure 9a , Figure 9b , Fig.10a , Fig.10b and Fig.11 A more detailed example of a UI that describes the results of the calibration check.

[0136] Figure 9a 1 is a diagram showing an example of a UI indicating that there is a problem with the connector assembly state in an application for calibration state checking according to various embodiments. The application for calibration state checking may be executed by a processor (e.g., processor 120) of electronic device 101. Processor 120 may display a UI about the application through a display (e.g., display 230). Figure 9a in Figure 8 Among the inspection items (inspection item 841, inspection item 842, inspection item 843, and inspection item 844), a case where the inspection result of inspection item 841 related to connector assembly is not good (NG) is described.

[0137] Reference Figure 9a In state 910, the electronic device 101 may display an inspection screen. In state 910, the electronic device 101 may display one or more inspection items. The one or more inspection items may include inspection item 911, inspection item 912, inspection item 913, and inspection item 914. Inspection item 911, inspection item 912, inspection item 913, and inspection item 914 may correspond to Figure 8 Inspection item 841, inspection item 842, inspection item 843 and inspection item 844.

[0138] The electronic device 101 may perform an inspection related to the connector assembly of inspection item 911. The electronic device 101 may identify the communication status of the connector of the distance detection sensor 210. The electronic device 101 may determine whether the communication connection between the processor 120 and the distance detection sensor 210 is normal through a specific process. In the case where the communication connection is abnormal, the electronic device 101 may determine that the connection of the connector of the distance detection sensor 210 is not good. The electronic device 101 may display the result of inspection item 911 as not good (NG). According to an embodiment, the electronic device 101 may perform an inspection on the connector assembly before other status checks. Since other status checks have not yet been performed, the electronic device 101 may not display the results of inspection item 912, the results of inspection item 913, and the results of inspection item 914.

[0139] After displaying the check screen, the electronic device 101 may display a notification screen to the user. For example, the electronic device 101 may change the state 910 to the state 920 after a certain period of time has passed. For another example, the electronic device 101 may change the state 910 to the state 920 in response to receiving a user input for performing the next step.

[0140] In state 920, the electronic device 101 may display a notification screen to the user. The notification screen may display an image object for notifying the user of a component (e.g., a connector) that has a problem connecting to the distance detection sensor 210. In addition, the notification screen may display a message for guiding the user's operation on the inspection result. For example, the message may include phrases such as "Communication with the sensor is not smooth. Check the fastening of the connector."

[0141] The determination of the connector assembly can be confirmed by a communication check with a sensor (e.g., a distance detection sensor 210). When the housing 300 (e.g., the rear glass) is assembled with the main body of the electronic device 101 by tape, when a sensor communication error occurs due to the connector not being assembled or being incorrectly assembled, the housing 300 must be removed again. However, since the housing 300 may be damaged during the process of removing it again, it may be safe to check in advance whether the connector is not assembled or incorrectly assembled. Before assembling the housing 300 to the main body, the user may send an input for checking the connector assembly. Through the function of the application for calibration status checking, the connector assembly of the inspection item 911 may be checked before the housing 300 is assembled to the main body. However, this description does not exclude the inspection of the connector assembly performed by the electronic device 101 after the housing 300 is assembled to the main body.

[0142] Figure 9b1 is a diagram showing an example of a UI indicating obstacle detection in an application for calibration status check according to various embodiments. The application for calibration status check may be executed by a processor of the electronic device 120 (e.g., the processor 120). The processor 120 may display a UI regarding the application through a display (e.g., the display 230). Figure 9b in Figure 8 Among the inspection items (inspection item 841, inspection item 842, inspection item 843, and inspection item 844), a case where the inspection result of inspection item 843 regarding an obstacle is not good (NG) is described.

[0143] Reference Figure 9b In state 960, the electronic device 101 may display an inspection screen. In state 960, the electronic device 101 may display one or more inspection items. The one or more inspection items may include inspection item 961, inspection item 962, inspection item 963, and inspection item 964. Inspection item 961, inspection item 962, inspection item 963, and inspection item 964 may correspond to Figure 8 Inspection item 841, inspection item 842, inspection item 843 and inspection item 844.

[0144] The electronic device 101 may display the inspection result of the connector assembly regarding inspection item 961 as "OK". The communication connection of the distance detection sensor 210 of the electronic device 101 may be normal. The electronic device 101 may display the inspection result of the IR environment regarding inspection item 962 as "OK". The electronic device 101 may be located in a normal light source environment. According to the sequential progress of each inspection item, the electronic device 101 may identify whether there are obstacles around the distance detection sensor 210.

[0145] The electronic device 101 may identify whether the crosstalk of the window 310 is detected by measuring the signal received through the distance detection sensor 210. According to an embodiment, in the case where a signal is received after a certain time from when the distance detection sensor 210 transmits a signal, the electronic device 101 may identify the reflection of an external object. The certain time may be set based on an air gap, which is the distance between the window 310 and the distance detection sensor 210. In addition, according to an embodiment, in the case where the distribution height of the intensity value measured in the distance area of ​​the distance detection sensor 210 is formed in the center of the light receiving unit (e.g., the light receiving unit 340), the electronic device 101 may identify the reflection of the external object. In addition, according to an embodiment, even if a reflection signal is received within a certain time from when the distance detection sensor 210 transmits a signal, or the distribution height of the intensity value measured in the distance area is formed in an area close to the light emitting unit (e.g., the light emitting unit 330), the electronic device 101 may also identify the reflection from the external object in the case where the intensity value (or a representative value of the intensity value) is greater than a threshold value. The electronic device 101 may recognize that the external object exists at a distance similar to the distance to the window 310.

[0146] Through the above operation, the electronic device 101 can perform an inspection on the obstacle of the inspection item 963. The obstacle may refer to, for example, an obstacle located within the detection range of the distance detection sensor 210. In the case where an obstacle is detected, the electronic device 101 may display the result of the inspection item 963 as not good (NG). The inspection of the connector assembly may be performed before the rear glass assembly is inspected. The electronic device 101 may not display the result of the inspection item 964.

[0147] After displaying the check screen, the electronic device 101 may display a notification screen to the user. For example, the electronic device 101 may change the state 960 to the state 970 after a certain period of time has passed. For another example, the electronic device 101 may change the state 960 to the state 970 in response to receiving a user input for continuing to the next step.

[0148] In state 970, the electronic device 101 may display a notification screen to the user. The notification screen may display an image object for notifying the user that an obstacle is located within the detection range of the distance detection sensor 210. In addition, the notification screen may display a message for guiding the user's operation on the check result to the user. For example, the message may include phrases such as "An obstacle was detected before performing calibration. Please clear the obstacle and execute".

[0149] Fig.10a is a diagram showing an example of crosstalk detection in an obstacle environment according to various embodiments. Fig.10a In the embodiment, there is described a distance detection sensor (eg, Figure 2The distance detection sensor (e.g., Figure 2 The distance detection sensor 210 may include a plurality of distance zones. For example, the distance detection sensor 210 may include 64 distance zones. In one distance zone, the light receiving unit (e.g., the light receiving unit 340) may receive a second signal reflected by a first signal emitted by a light emitting unit (e.g., the light emitting unit 330). The distance detection sensor 210 may measure the second signals received in the plurality of distance zones of the light receiving unit.

[0150] Reference Fig.10a The histogram 1000 represents the SPAD counts of the distance detection sensor 210 at each time. The abscissa axis 1001 of the histogram 1000 represents time, and the ordinate axis 1002 of the histogram 1000 represents the SPAD counts (unit: KCPS).

[0151] Bin 1010 represents the SPAD count of the crosstalk. Bin 1020 represents the SPAD count of the signal reflected by the external object (e.g., an object located at a distance of 5 cm). Referring to histogram 1000, interference 1077 may be observed due to the external object placed in a close position. Electronic device 101 may determine whether bin 1010 is the crosstalk of window 310. Due to interference 1077, the value of bin 1010 determined as the crosstalk of window 310 may be different from the value of the crosstalk of a general window.

[0152] The electronic device 101 may identify whether the bin 1010 and the interference 1077 are caused by the overlap of the external object and the window 310, or by the external object instead of the window 310. According to an embodiment, the electronic device 101 may use the peak signal value of the distance detection sensor 210 to identify whether a specific type of crosstalk (e.g., the bin 1010) is caused by the window 310. The electronic device 101 may identify whether the housing 300 including the window 310 is not assembled based on identifying whether the peak signal value of the distance detection sensor 210 is less than a threshold value. In addition, the electronic device 101 may identify the presence of an external object by having the peak signal value be equal to or greater than a threshold value.

[0153] Fig.10b 1 is a diagram showing an example of a UI indicating that the housing is not assembled in an application for calibration status check according to various embodiments. The application for calibration status check may be executed by a processor (e.g., processor 120) of the electronic device 101. The processor 120 may display a UI about the application through a display (e.g., display 230). Fig.10b in Figure 8Among the inspection items (inspection item 841, inspection item 842, inspection item 843, and inspection item 844), a case where the inspection result of inspection item 844 regarding an obstacle is not good (NG) is described.

[0154] Reference Fig.10b In state 1060, the electronic device 101 may display an inspection screen. In state 1060, the electronic device 101 may display one or more inspection items. The one or more inspection items may include inspection item 1061, inspection item 1062, inspection item 1063, and inspection item 1064. Inspection item 1061, inspection item 1062, inspection item 1063, and inspection item 1064 may correspond to Figure 8 Inspection item 841, inspection item 842, inspection item 843 and inspection item 844.

[0155] The electronic device 101 may display the inspection result of the connector assembly regarding inspection item 1061 as "OK". The communication connection of the distance detection sensor 210 of the electronic device 101 may be normal. The electronic device 101 may display the inspection result of the IR environment regarding inspection item 1062 as "OK". The electronic device 101 may be located in a normal light source environment. The electronic device 101 may display the inspection result of the obstacle regarding inspection item 1063 as "OK". The obstacle may not be located within the detection range of the distance detection sensor 210 of the electronic device 101. According to the sequential progress of each inspection item, the electronic device 101 may identify whether the housing 300 (e.g., the rear glass) is assembled.

[0156] The electronic device 101 may identify whether the crosstalk of the window 310 is detected by measuring the signal received through the distance detection sensor 210. According to an embodiment, if the intensity value measured in the distance area of ​​the distance detection sensor 210 is less than the threshold value, the electronic device 101 may identify whether the result of the intensity value is due to the non-assembly of the housing 300 or due to the reflection of the window 310.

[0157] The electronic device 101 may identify a peak signal in the distance area of ​​the distance detection sensor 210. The electronic device 101 may identify whether the housing 300 is not assembled by comparing the intensity value of the peak signal with a threshold value. In the case where the peak signal is less than the threshold value, the electronic device 101 may identify that the housing 300 (e.g., the rear glass) is not assembled. The electronic device 101 may display the result of the inspection item 1064 as not good (NG).

[0158] After displaying the check screen, the electronic device 101 may display a notification screen to the user. For example, the electronic device 101 may change the state 1060 to the state 1070 after a certain period of time has passed. For another example, the electronic device 101 may change the state 1060 to the state 1070 in response to receiving a user input for performing the next step.

[0159] In state 1070, the electronic device 101 may display a notification screen to the user. The notification screen may display an image object indicating that the rear glass is not assembled to the user. In addition, the notification screen may display a message to the user to guide the user's operation on the inspection result. For example, the message may include phrases such as "Rear glass is not detected. If not assembled, perform calibration after assembling the rear glass".

[0160] Fig.11 1 is a diagram showing an example of checking the calibration status according to various embodiments. An application for checking the calibration status may be executed by a processor (eg, processor 120) of the electronic device 101. The processor 120 may display a UI about the application through a display (eg, display 230). Fig.11 In, it is described Figure 8 The situation where all of the inspection items (inspection item 841, inspection item 842, inspection item 843 and inspection item 844) have passed.

[0161] Reference Fig.11 In state 1110, the electronic device 101 may display an inspection screen. In state 1110, the electronic device 101 may display one or more inspection items. The one or more inspection items may include inspection item 1111, inspection item 1112, inspection item 1113, and inspection item 1114.

The communication connection of the distance detection sensor 210 of the electronic device 101 may be normal. The electronic device 101 may display the inspection result of the IR environment regarding inspection item 1112 as "OK". The electronic device 101 may be located in a normal light source environment. The electronic device 101 may display the inspection result of the obstacle regarding inspection item 1113 as "OK". The obstacle may not be located within the detection range of the distance detection sensor 210 of the electronic device 101. The electronic device 101 may display the inspection result of the assembly of the housing 300 (e.g., rear glass) regarding inspection item 1114 as "OK". The window 310 of the housing 300 may be normally located in the position according to the assembly.

[0163] After displaying the check screen, the electronic device 101 may display a notification screen to the user. For example, the electronic device 101 may change the state 1110 to the state 1120 after a certain period of time has passed. For another example, the electronic device 101 may change the state 1110 to the state 1120 in response to receiving a user input for performing the next step. In the state 1120, the electronic device 101 may display a notification screen to the user. The notification screen may display a message 1121 indicating that the calibration state check of the distance detection sensor 210 has passed to the user.

[0164] Although not in Fig.11 , according to an embodiment, the electronic device 101 may output a sound signal indicating that the calibration status check of the distance detection sensor 210 has passed, instead of a message indicating that the calibration status check has passed, or in addition to the message, may output a sound signal indicating that the calibration status check of the distance detection sensor 210 has passed. According to an embodiment, the electronic device 101 may output a notification indicating that the calibration status check of the distance detection sensor 210 has passed through a device (e.g., a light). For example, a green light may indicate that the calibration status check of the distance detection sensor 210 has passed.

[0165] exist Figure 8 , Figure 9a , Figure 9b , Fig.10a , Fig.10b and Fig.11 The progress of all steps is shown in Fig.11 Status 1110 is merely an example, and embodiments of the present disclosure are not limited thereto. In consideration of user convenience, the display of the "OK" notification may be omitted. According to an embodiment, the electronic device 101 may display the screen of status 1120 only when the calibration status check passes, and may display only comments on the phenomenon in which the problem occurred in other cases. For example, in the event that a problem occurs when assembling a connector, the electronic device 101 may directly display the screen of status 920 without displaying a pass / fail screen for each item (e.g., the screen of status 910).

[0166] Fig.12 is a flowchart illustrating an example operation of an electronic device for calibration status checking according to various embodiments. Figure 2 processor 120) to execute the electronic device (e.g., Figure 1 operation of the electronic device 101).

[0167] Reference Fig.12In operation 1201, the electronic device 101 may identify whether the connection of the distance detection sensor (e.g., the distance detection sensor 210) is normal. The electronic device 101 may identify whether the communication state with the distance detection sensor 210 is normal. This is because if the control signal of the processor 120 of the electronic device 101 does not reach the distance detection sensor 210, it is difficult to normally perform the operation of the distance detection sensor 210 (e.g., the camera switching operation). For example, if the connector of the distance detection sensor 210 is not normally connected to the FPCB or the PBA, the electronic device 101 may determine that the communication state is abnormal.

[0168] In the case that the connection of the distance detection sensor 210 is normal, the electronic device 101 may perform operation 1203. In the case that the connection of the distance detection sensor 210 is not normal, the electronic device 101 may perform operation 1221.

[0169] In operation 1203, the electronic device 101 may identify whether the environmental value is less than a threshold value (e.g., about 35 kcps). The electronic device 101 may identify whether there is an external light source that interferes in the signal radiated from the distance detection sensor 210. In the case where the environmental value is less than the threshold value, the electronic device 101 may perform operation 1205. In the case where the environmental value is equal to or greater than the threshold value, the electronic device 101 may perform operation 1223.

[0170] In operation 1205, the electronic device 101 may send a calibration signal. The electronic device 101 may perform calibration on the distance detection sensor 210. The electronic device 101 may send a first signal through a light emitting unit (e.g., light emitting unit 330) of the distance detection sensor 210. The first signal may have a specific frequency. The first signal may be used for calibration of the distance detection sensor 210 described later.

[0171] In operation 1207, the electronic device 101 may identify whether the calibration is normal. The electronic device 101 may receive the second signal through the light receiving unit (e.g., the light receiving unit 340) of the distance detection sensor 210. The second signal may be received when the first signal is reflected by an external object or an internal component. The electronic device 101 may receive the second signal reflected by the first signal.

[0172] The electronic device 101 may measure the intensity value of the second signal in a plurality of distance regions of the distance detection sensor 210. The electronic device 101 may identify whether crosstalk is detected based on the intensity value. According to an embodiment, the electronic device 101 may identify whether crosstalk is detected based on distribution information about the intensity value of the second signal. For example, in the distance region of the light receiving unit 340, the signal intensity of the distance region close to the light emitting unit 330 may be formed to be high. The electronic device 101 may identify that crosstalk is detected. The electronic device 101 may identify that calibration is normal based on identifying that crosstalk is detected.

[0173] In the case where the calibration is normal, the electronic device 101 may perform operation 1209. In the case where the calibration is not normal, in other words, in the case where an error is detected in the calibration, the electronic device 101 may perform operation 1215.

[0174] In operation 1209, the electronic device 101 may identify whether the crosstalk is less than a threshold value (e.g., about 200 kcps). The electronic device 101 may determine whether the crosstalk is caused by a foreign object adjacent to the window 310 of the housing 300 or by the window 310. In the case where the crosstalk is less than the threshold value, the electronic device 101 may determine that the crosstalk is caused by the window 310. In the case where the crosstalk is less than the threshold value, the electronic device 101 may perform operation 1211. In the case where the crosstalk is equal to or greater than the threshold value, the electronic device 101 may perform operation 1213.

[0175] In operation 1211, the electronic device 101 may recognize that the calibration status check has passed. According to an embodiment, the electronic device 101 may display a notification indicating that the calibration status check has passed through a display. In addition, according to an embodiment, the electronic device 101 may output a sound signal indicating that the calibration status check has passed.

[0176] Furthermore, according to an embodiment, the electronic device 101 may output a vibration indicating that the calibration status check has passed.

[0177] Furthermore, according to an embodiment, the electronic device 101 may output a notification indicating that the calibration status check has passed through a device (eg, an LED light).

[0178] The electronic device 101 may request confirmation of the assembly state or may request removal of foreign matter in operation 1213. Even if crosstalk is detected from the measurement results in each distance zone, the electronic device 101 may determine that the calibration state check has failed.

[0179] According to an embodiment, if the intensity of the crosstalk is equal to or greater than the threshold value (e.g., about 200 kcps) of operation 1209, the electronic device 101 may determine that there is an obstacle that blocks the signal transmission of the distance detection sensor 210. The electronic device 101 may provide a message requesting the user to remove the foreign object. For example, the electronic device 101 may display a message including the phrase "clean the window or remove the object in front of the window" through a display (e.g., display 230).

[0180] According to an embodiment, when the intensity of the crosstalk is equal to or greater than the threshold value (e.g., about 200 kcps) of operation 1209, the electronic device 101 may recognize that the housing 300 is twistedly assembled. Due to the deformation of the housing 300, one surface of the window 310 may not be set to face the distance detection sensor 210. Since another area of ​​the housing 300 other than the window 310 is set to face the distance detection sensor 210, it can be detected that the measured intensity value of the second signal is high. Therefore, the electronic device 101 may provide a message requesting confirmation of the assembly state to the user. For example, the electronic device 101 may display a message including the phrase "If the rear glass is twistedly assembled, please reassemble" through a display (e.g., display 230).

[0181] In operation 1215, the electronic device 101 may identify whether the intensity of the peak signal is less than a threshold value (e.g., about 200 kcps). Here, the intensity of the peak signal may refer to, for example, the peak intensity in each of the distance zones of the distance detection sensor 210. In the case where the peak signal is less than the threshold value (e.g., the peak intensity in each of the distance zones is all less than the threshold value), the electronic device 101 may perform operation 1217. In the case where the peak signal is not less than the threshold value, the electronic device 101 may perform operation 1219.

[0182] In operation 1217, the electronic device 101 may request confirmation of the assembly state. When the peak signal is less than a threshold value (e.g., about 200 kcps), the electronic device 101 may recognize that the housing 300 is not assembled to the body. Therefore, the electronic device 101 may provide a message requesting confirmation of the assembly state to the user. For example, the electronic device 101 may display a message including a phrase "Check whether the rear glass is assembled correctly" through a display (e.g., display 230).

[0183] In operation 1219, the electronic device 101 may request to remove the foreign object. If the peak signal is equal to or greater than a threshold value (e.g., 200 kcps), the electronic device 101 may recognize that there is an object blocking the advancing direction of the calibration signal of the distance detection sensor 210. Therefore, the electronic device 101 may provide a message requesting the user to remove the foreign object. For example, the electronic device 101 may display a message including the phrase "clean the window or remove the object in front of the window" through a display (e.g., display 230).

[0184] In operation 1221, the electronic device 101 may request confirmation of the light source environment. The electronic device 101 may identify an abnormal light source environment based on a detection environment value being equal to or greater than a threshold value (approximately 35 kcps). The electronic device 101 may recognize that it is an environment in which there is a light source that may interfere around the current electronic device 101 (e.g., a sunlight environment, an environment in which there is an external IR light source). The electronic device 101 may determine that the current environment is not suitable for calibration through a signal (e.g., an IR signal) from the distance detection sensor 210. Therefore, the electronic device 101 may provide a message to the user requesting confirmation of the light source environment. For example, the electronic device 101 may display a message including the phrase "Perform calibration away from an IR light source or a sunlight environment" through a display (e.g., display 230).

[0185] In operation 1223, the electronic device 101 may request confirmation of the connection state of the distance detection sensor. In the case where the sensor communication is not normal, the electronic device 101 may recognize that there is a problem with the connector assembly state of the distance detection sensor 210. Therefore, the electronic device 101 may provide a message requesting confirmation of the connection state of the distance detection sensor to the user. For example, the electronic device 101 may display a message including the phrase "Check the connector assembly of the distance detection sensor" through a display (e.g., display 230).

[0186] According to an embodiment, the electronic device 101 can identify whether the housing 300 (e.g., rear glass) is assembled to the body of the electronic device 101 by determining whether the value of the peak signal is equal to or greater than a threshold value (e.g., 200 kpcs). In addition, even if the housing 300 is assembled, the electronic device 101 can detect whether an object is blocked between the window 310 of the housing 300 and the distance detection sensor 210.

[0187] The electronic device and method according to the embodiment can provide convenience after the user self-repairs through an application for calibration. After self-repair, the user can identify whether the housing and the main body of the electronic device are normally assembled before using the electronic device, and the user can use the electronic device normally based on the inspection result. By determining the assembly state of the electronic device through a distance detection sensor and providing the user with status information about the electronic device, when the user performs self-repair, failures due to incorrect assembly may not occur or occur less frequently. In addition, the electronic device 101 can mainly determine whether the assembly of the housing 300 is normal based on the shape and value of the detected crosstalk. In addition, regardless of whether the housing 300 is assembled, through the function of the application (for example, checking the sensor communication status), it is possible to detect that the connector of the distance detection sensor 210 is not assembled or incorrectly assembled.
