Description

An electronic device including a distance sensor, a method of operation thereof, and a storage medium storing a program for performing the method of operation

[0001] The present disclosure relates to an electronic device including a distance sensor, a method of operating the same, and a storage medium storing a program for performing the method of operating the same.

[0002] An electronic device (e.g., a smartphone) may include a plurality of cameras. For example, the electronic device may include a plurality of cameras positioned on the rear of the electronic device in addition to at least one camera positioned on the front of the electronic device.

[0003] An electronic device can select a camera for acquiring an image from among multiple cameras with different focal lengths (e.g., multiple cameras positioned on the rear of the electronic device) based on the distance between the electronic device and a subject (object). For example, among the multiple cameras, the electronic device can select a camera with a longer focal length as the distance between the electronic device and the subject increases as the distance increases as the distance increases, as the camera for acquiring the image.

[0004] An electronic device may include a distance sensor for measuring the distance between the electronic device and a subject. An electronic device including a distance sensor may select a camera for acquiring an image from among multiple cameras with different focal lengths by utilizing the distance information between the electronic device and the subject obtained through the distance sensor. Additionally, an electronic device including a distance sensor may utilize the distance information between the electronic device and the subject measured by the distance sensor for an autofocus (AF) function. Alternatively, the electronic device may utilize the distance information obtained through the distance sensor for other functions or provide it to another device.

[0005] The electronic device may include a single-zone distance sensor that has a relatively small volume and cost but a relatively narrow field of view (FOV). When the electronic device uses a single-zone distance sensor, the single-zone distance sensor may not sufficiently cover the shooting area of ​​the electronic device's camera.

The instructions may be executed collectively or individually by said at least one processor to enable the electronic device to determine whether said first sensor information satisfies a designated condition. The above instructions may be executed collectively or individually by the at least one processor to cause the electronic device to determine a weight related to the correction value based on the first sensor information based on the first sensor information satisfying the specified condition. The above instructions may be executed collectively or individually by the at least one processor to cause the electronic device to adjust the correction value based on the weight to a value that corrects a second crosstalk signal value different from the first crosstalk signal value. The above instructions may be executed collectively or individually by the at least one processor to cause the electronic device to correct a second signal obtained from the distance sensor based on the adjusted correction value to obtain second sensor information.

For example, the distance sensor (321) may be placed to face the same direction as the direction in which at least one camera (311, 312, 313, 314) included in the camera module (e.g., the camera module (180) of FIG. 1) of the electronic device (e.g., the electronic device (101) of FIG. 1) faces. For example, the distance sensor (321) may be placed adjacent to at least one camera (311, 312, 313, 314) included in the camera module (e.g., the camera module (180) of FIG. 1) of the electronic device (e.g., the electronic device (101) of FIG. 1), but the position of the distance sensor (321) is not limited as shown in FIG. 3.

[0070] In the present disclosure, when one component (e.g., distance sensor (321)) of an electronic device (e.g., electronic device (101) of FIG. 1) is positioned "adjacently" to another component (e.g., at least one camera (311, 312, 313, 314)), it may mean that one component (e.g., distance sensor (321)) is positioned to be physically "in contact" with another component (e.g., at least one camera (311, 312, 313, 314)) or that the "separation distance" between one component (e.g., distance sensor (321)) and another component (e.g., at least one camera (311, 312, 313, 314)) is within a predetermined range.

[0071] FIG. 4 illustrates a rear view of an electronic device according to one embodiment of the present disclosure.

[0072] The electronic device (400) of FIG. 4 can correspond to the electronic device (101) of FIG. 1.

[0073] Referring to FIG. 4, an electronic device (400) according to one embodiment may include a distance sensor (421), at least one camera (411, 412, 413, 414), and an illuminance sensor (430). The distance sensor (421) of FIG. 4 may correspond to the distance sensor (201) of FIG. 2 and the distance sensor (321) of FIG. 3. The at least one camera (411, 412, 413, 414) of FIG. 4 may correspond to the at least one camera (311, 312, 313, 314) of FIG. 3. The illuminance sensor (430) of FIG. 4 may be included in the sensor module (176) of FIG. 1.

[0074] An electronic device (400) according to one embodiment can obtain brightness information of light around the electronic device (400) through an illuminance sensor (430). For example, the illuminance sensor (430) can detect light. For example, the value of the resistance of the illuminance sensor (430) can change according to a change in the amount of photons of the detected light. For example, the electronic device (400) can obtain information related to the intensity of light around the electronic device (400) based on a change in the voltage value of the illuminance sensor (430) according to a change in the value of the resistance of the illuminance sensor (430). For example, the illuminance sensor (430) may include a flicker sensor for detecting a flicker phenomenon.

[0075] According to one embodiment, the distance sensor (421) and the illuminance sensor (430) may be placed adjacent to one area of ​​the electronic device (400).

[0076] According to one embodiment, the distance sensor (421) may protrude in one direction outside the electronic device (400), so that at least a portion may be exposed.

[0077] FIG. 5 illustrates a distance sensor and a window coupled to the distance sensor according to one embodiment of the present disclosure.

[0078] The distance sensor (501) of FIG. 5 may be included in the sensor module (176) of FIG. 1. The distance sensor (501) of FIG. 5 may correspond to the distance sensor (201) of FIG. 2, the distance sensor (321) of FIG. 3, or the distance sensor (421) of FIG. 4.

[0079] According to one embodiment, a window (530) may be attached to one side of the distance sensor (501). For example, one side of the distance sensor (501) may refer to the side of the distance sensor (421) of FIG. 4 that is exposed in the electronic device (400) of FIG. 4. For example, the window (530) may be attached to the distance sensor (501) to cover the exposed area of ​​one side of the distance sensor (501). As a result, the window (530) can prevent the distance sensor (501) from being damaged by external impact to the electronic device (e.g., the electronic device (101) of FIG. 1).

[0080] According to one embodiment, the window (530) may include at least one filter (531, 532). For example, the window (530) may include a first filter (531) and a second filter (532). In FIG. 5, the window (530) is shown as including two physically separated filters (531, 532), but is not limited thereto. For example, the filters (531, 532) may be formed as a single unit, and additional filters (not shown) may be added depending on the structure of the distance sensor (501).

[0081] According to one embodiment, at least one filter (531, 532) may be placed in the window (530) to correspond to the light-emitting part (510) and the light-receiving part (520) of the distance sensor (501) when the distance sensor (501) and the window (530) are combined. For example, when the distance sensor (501) and the window (530) are combined, the first filter (531) may be placed to correspond to the light-emitting part (510) of the distance sensor (501). For example, when the distance sensor (501) and the window (530) are combined, the second filter (532) may be placed to correspond to the light-receiving part (520) of the distance sensor (501).

[0082] According to one embodiment, at least one filter (531, 532) may be formed of a light-transmitting material. In the present disclosure, "light-transmitting" may mean that at least a portion of incident light can pass through. For example, at least one filter (531, 532) may be formed of a material through which infrared light can pass. For example, at least a portion of light incident on one side of at least one filter (531, 532) may pass through at least one filter (531, 532). For example, at least a portion of light incident on one side of at least one filter (531, 532) may be reflected by at least one filter (531, 532).

[0083] According to one embodiment, light of a designated band emitted from the light-emitting unit (510) may pass through the first filter (531) and be emitted outside the electronic device (e.g., the electronic device (101) of FIG. 1). According to one embodiment, light incident on one side of the second filter (532) outside the electronic device (e.g., the electronic device (101) of FIG. 1) may pass through the second filter (532) and be detected by the light-receiving unit (520).

[0084] FIG. 6 is a cross-sectional view of an example of a distance sensor and a window combined according to one embodiment of the present disclosure.

[0085] The distance sensor (601) of FIG. 6 may correspond to the distance sensor (201) of FIG. 2, the distance sensor (321) of FIG. 3, the distance sensor (421) of FIG. 4, and the distance sensor (501) of FIG. 5. The window (603) of FIG. 6 may correspond to the window (530) of FIG. 5.

[0086] Referring to FIG. 6, a window (603) according to one embodiment may be coupled with a distance sensor (601) at a predetermined distance (602).

[0087] A light-emitting part (610) of a distance sensor (601) according to one embodiment may include a light-emitting element that emits light of a designated band. For example, the light-emitting part (610) may include a laser diode that emits infrared light. For example, the light-emitting part (610) may include a vertical cavity surface emitting laser (VCSEL) that emits infrared light.

[0088] A distance sensor (601) according to one embodiment may include a light receiving unit (620) including a light receiving element (640). For example, the light receiving element (640) of the light receiving unit (620) may include a photodiode (PD) that detects infrared light. For example, the light receiving element (640) may include a CMOS sensor.

[0089] A distance sensor (601) according to one embodiment may include at least one filter (651, 652). The at least one filter (651, 652) of FIG. 6 may correspond to at least one filter (531, 532) of FIG. 5. For example, the first filter (651) of FIG. 6 may correspond to the first filter (531) of FIG. 5. For example, the second filter (652) of FIG. 6 may correspond to the second filter (532) of FIG. 5. The at least one filter (651, 652) may be configured to transmit light of a designated band and block light of another band.

[0090] A distance sensor (601) according to one embodiment may include a lens (660). For example, the lens (660) may be positioned adjacent to one side of the second filter (652). For example, the lens (660) may include a convex lens. For example, the lens (660) may be formed to refract light (e.g., first reflected light (621)) incident on the lens (660) so that it is incident on the light receiving element (640). In FIG. 6, the distance sensor (601) is shown as including only one lens (660), but is not limited thereto. For example, the distance sensor (601) may include a lens (not shown) positioned between the light-emitting part (610) and the first filter (651).

[0091] A distance sensor (601) according to one embodiment may include a support member (690) formed to surround at least a portion of a light-emitting part (610) and a light-receiving part (620). For example, the support member (690) may be formed to support a first filter (651), a second filter (652), and a lens (660) so as to face each other at a predetermined distance from the light-emitting part (610) and the light-receiving part (620). For example, one side of the support member (690) may include at least one step formed to allow the first filter (651), the second filter (652), and the lens (660) to be placed.

[0092] According to one embodiment, the light-emitting part (610) of the distance sensor (601) can emit a first emitted light (611) that passes through a first filter (651). For example, the first emitted light (611) that passes through the first filter (651) can pass through a window (603). For example, the first emitted light (611) that passes through the window (603) can be reflected by an external object (e.g., the external object (750) of FIG. 7). For example, the first reflected light (621) that is reflected by the external object (e.g., the external object (750) of FIG. 7) can pass through a second filter (652). For example, the first reflected light (621) that passes through the second filter (652) can pass through a lens (660). For example, the first reflected light (621) that passes through the lens (660) can be incident on the light receiving element (640).

[0093] According to one embodiment, the light receiving unit (620) of the distance sensor (601) can detect a first reflected light (621) reflected by an external object (e.g., the external object (750) of FIG. 7). For example, the light receiving element (640) of the light receiving unit (620) can detect the first reflected light (621). For example, the light receiving element (640) of the light receiving unit (620) can generate an electronic signal based on the amount of photons contained in the detected first reflected light (621).

[0094] According to one embodiment, the light receiving unit (620) may include a plurality of zones. For example, the plurality of zones may each include physically separated zones. For example, each of the plurality of zones may correspond to at least one light receiving element (640) within the light receiving unit (620). For example, the distance sensor (601) may acquire distance information (e.g., distance information (1420) of FIG. 14) of an external object (e.g., external object (750) of FIG. 7) for each of the plurality of zones. The operation of the distance sensor (601) acquiring distance information (e.g., distance information (1420) of FIG. 14) for each of the plurality of zones may be associated with FIG. 14. This will be explained in detail with reference to FIG. 14.

[0095] FIG. 7 illustrates an example of a signal obtained through a distance sensor by an electronic device according to one embodiment of the present disclosure.

[0096] Referring to FIG. 7, an electronic device according to one embodiment (e.g., the electronic device (101) of FIG. 1) may acquire a signal (702) associated with the flight-time of light of a specified band through a distance sensor (710). For example, operation (701) may be understood as an overview to explain an example of the distance sensor (710) acquiring the signal (702) associated with the flight-time. For example, the signal (702) may include data obtained by processing information acquired through the distance sensor (710) into the form of a histogram. For example, in the signal (702), the horizontal axis of the histogram may be defined as a bin representing a predetermined unit of time (e.g., 1 ns). For example, in signal (702), the vertical axis of the histogram can be defined as a unit (e.g., count per second, cps) that defines the number of photons detected per unit time or the number of photon detection events.

[0097] According to one embodiment, a signal (702) obtained by an electronic device (e.g., the electronic device (101) of FIG. 1) through a distance sensor (710) may include information related to the distance of an external object (750). For example, a first emitted light (751) emitted through the light-emitting part (720) of the distance sensor (710) may be reflected by the external object (750). For example, a first reflected light (752) reflected by the external object (750) may be detected by a light-receiving part (730). For example, a first part (b) of the signal (702) may include a signal indicating the flight time (e.g., 40ns) and the number of photons (e.g., 50kcps) from the time the first emitted light (751) is emitted by the light-emitting part (720) until the first reflected light (752) is detected by the light-receiving part (730). For example, the signal (770) included in the first part (b) of the signal (702) may include information related to the distance of an external object (750).

[0098] According to one embodiment, a signal (702) obtained by an electronic device (e.g., the electronic device (101) of FIG. 1) through a distance sensor (710) may include a crosstalk signal (e.g., a first crosstalk signal value (760)). In this disclosure, "crosstalk" may be referred to as a term meaning a signal containing a noise component, which is an unintended signal. For example, the signal (702) may include a first crosstalk signal value (760) generated by a window (740). For example, the first crosstalk signal value (760) included in a second portion (a) of the signal (702) may include a signal generated based on a second reflected light (742) reflected by a window (740) from a second emitted light (741) of a designated band emitted from a light-emitting unit (720). For example, the second reflected light (742) reflected by the window (740) can be detected by the light receiving unit (730).

[0099] According to one embodiment, the electronic device (e.g., the electronic device (101) of FIG. 1) determines distance information based on a first interference signal value (760) rather than a signal (770) detected by an external object (750), so that the accuracy of the distance information obtained through the distance sensor (710) may be lowered due to the first interference signal value (760).

[0100] FIG. 8 illustrates an example of correcting a first crosstalk signal value detected through a distance sensor according to one embodiment of the present disclosure.

[0101] The signal (801) of Fig. 8 can correspond to the signal (702) of Fig. 7.

[0102] The horizontal and vertical axes of the histogram shown in FIG. 8 may correspond to the horizontal and vertical axes of the histogram in FIG. 7.

[0103] An electronic device according to one embodiment (e.g., the electronic device (101) of FIG. 1) can remove (820) a first crosstalk signal value (810) included in a signal (801). For example, the electronic device (e.g., the electronic device (101) of FIG. 1) can correct the first crosstalk signal value (810) based on a correction value of a distance sensor (e.g., the distance sensor (201) of FIG. 2). In the present disclosure, the "correction value" may include a parameter used to correct a signal (e.g., the signal (801) of FIG. 8) obtained through a distance sensor (e.g., the distance sensor (201) of FIG. 2). For example, the electronic device (e.g., the electronic device (101) of FIG. 1) can store a correction value corresponding to the identified first crosstalk signal value (810) in a memory (e.g., the memory (130) of FIG. 1). For example, an electronic device (e.g., the electronic device (101) of FIG. 1) can remove a first crossover signal value (810) included in a signal (801) based on a correction value stored in a memory (e.g., the memory (130) of FIG. 1). For example, the operation of the electronic device (e.g., the electronic device (101) of FIG. 1) removing the first crossover signal value (810) may include an operation of subtracting a correction value stored for a specified index from the detected signal.

[0104] According to one embodiment, an electronic device (e.g., the electronic device (101) of FIG. 1) can obtain sensor information (802) in which the first crosstalk signal value (810) is removed from a signal (801) containing the first crosstalk signal value (810). As a result, the electronic device (e.g., the electronic device (101) of FIG. 1) can obtain more accurate distance information for an external object (e.g., the external object (750) of 7).

[0105] According to one embodiment, a correction value stored in a memory (e.g., memory (130) of FIG. 1) for removing (820) the first crosstalk signal value (810) may be determined during the manufacturing stage of an electronic device (e.g., electronic device (101) of FIG. 1). For example, the correction value stored in a memory (e.g., memory (130) of FIG. 1) for removing (820) the first crosstalk signal value (810) may be determined experimentally in correspondence with a distance sensor (e.g., distance sensor (201) of FIG. 2) of an electronic device (e.g., electronic device (101) of FIG. 1) or a window (e.g., window (530) of FIG. 5) coupled to a distance sensor (e.g., distance sensor (201) of FIG. 2) for calibration of a distance sensor (e.g., distance sensor (201) of FIG. 2).

[0106] FIG. 9 illustrates an example in which an external cover is coupled to a distance sensor according to one embodiment of the present disclosure.

[0107] The electronic device (901) of FIG. 9 may correspond to the electronic device (101) of FIG. 1 or the electronic device (400) of FIG. 4.

[0108] According to one embodiment, a cover (911) may be attached to at least a portion of a window (910) attached to a distance sensor (e.g., distance sensor (421) of FIG. 4) of an electronic device (901). The cover (911) is attached to the window (910) attached to the distance sensor (e.g., distance sensor (421) of FIG. 4) to prevent the distance sensor (e.g., distance sensor (421) of FIG. 4) from being damaged by external impact. A portion of the light emitted from the light-emitting part (e.g., light-emitting part (510) of FIG. 5) of the distance sensor (e.g., distance sensor (421) of FIG. 4) may be reflected by the cover (911) and detected by a light-receiving part (e.g., light-receiving part (520) of FIG. 5). The value of the crosstalk signal detected by the light-receiving part (e.g., light-receiving part (520) of FIG. 5) may change due to the light reflected by the cover (911).

[0109] The cover (911) of FIG. 9 illustrates an example of an external product coupled to a distance sensor (e.g., the distance sensor (421) of FIG. 4), and the shape of the external product coupled to the distance sensor (e.g., the distance sensor (421) of FIG. 4) is not limited to the example shown in FIG. 9.

[0110] FIG. 10 illustrates an example in which a crosstalk signal value in a signal obtained through a distance sensor according to one embodiment of the present disclosure changes.

[0111] The horizontal and vertical axes of the histogram shown in FIG. 10 may correspond to the horizontal and vertical axes of the histogram in FIG. 7.

[0112] The signal (1001) of FIG. 10 may correspond to the signal (702) of FIG. 7 or the signal (801) of FIG. 8. The first interference signal value (1010) included in the signal (1001) of FIG. 10 may correspond to the first interference signal value (760) of FIG. 7 or the first interference signal value (810) of FIG. 8.

[0113] The first signal (1002) of FIG. 10 can be understood as an example of a signal obtained through a distance sensor (e.g., distance sensor (201) of FIG. 2) while the cover (911) is attached to the window (e.g., window (910) of FIG. 9).

[0114] According to one embodiment, the first signal (1002) may include a second interference signal value (1020). For example, the second interference signal value (1020) may include an interference signal caused by a window (e.g., the window (910) of FIG. 9) and a cover (e.g., the cover (911) of FIG. 9). For example, the second interference signal value (1020) may include a value different from the first interference signal value (1010). For example, the second interference signal value (1020) may include a value greater than the first interference signal value (1010).

[0115] According to one embodiment, an electronic device (e.g., the electronic device (101) of FIG. 1) may obtain distance information with low reliability due to a signal containing a crosstalk signal. In this disclosure, "reliability" may be referred to as a term meaning the accuracy of distance information obtained through a distance sensor (e.g., the distance sensor (201) of FIG. 2). For example, the criteria for determining reliability may include a standard divided into multiple values. For example, the signal-to-noise ratio (SNR) may be used to measure reliability. For example, a confidence level based on a depth 16 format may be used as a criterion for determining reliability. The confidence level may refer to a standard that indicates a reliability range divided into values ​​from 0 to 7, as shown in Table 1 below. For example, a confidence level of 0 may indicate 100% reliability. For example, a confidence level of 1 may indicate 0% reliability. For example, if the confidence level is 2, it can indicate a confidence of 1 / 7. For example, if the confidence level is 3, it can indicate a confidence of 2 / 7.

[0116] [Table 1]

[0117]

[0118] According to one embodiment, if the reliability of distance information obtained through a distance sensor (e.g., distance sensor (201) of FIG. 2) is low, the focus adjustment function (e.g., auto focusing) of a camera module (e.g., camera module (180) of FIG. 1) may not be fully performed. For example, if the reliability of distance information measured through a distance sensor (e.g., distance sensor (201) of FIG. 2) is low, an unnecessary switching of the camera may occur.

[0119] FIG. 11 illustrates a flowchart of an operation in which an electronic device according to one embodiment of the present disclosure calibrates a distance sensor.

[0120] The memory (e.g., memory (130) of FIG. 1) of the electronic device (e.g., electronic device (101) of FIG. 1) performing the operation 1110 of FIG. 11 can store a correction value for correcting a first crosstalk signal value (e.g., first crosstalk signal value (1010) of FIG. 10) detected from a distance sensor (e.g., distance sensor (201) of FIG. 2).

[0121] Referring to FIG. 11, an electronic device according to one embodiment (e.g., the electronic device (101) of FIG. 1) can obtain first sensor information by correcting a first signal (e.g., the first signal (1002) of FIG. 10) obtained through a distance sensor (e.g., the distance sensor (201) of FIG. 2) based on a correction value that corrects a first crosstalk signal value (e.g., the first signal (1002) of FIG. 1) stored in a memory (e.g., the memory (130) of FIG. 1)) in operation 1110. For example, the signal included in the first sensor information may include a signal in which a second crosstalk signal value (e.g., the second crosstalk signal value (1020) of FIG. 10) included in the first signal (e.g., the first signal (1002) of FIG. 10) is corrected by an amount corresponding to the first crosstalk signal value (e.g., the first crosstalk signal value (1010) of FIG. 10).

[0122] An electronic device according to one embodiment (e.g., the electronic device (101) of FIG. 1) may determine, in operation 1120, whether the first sensor information satisfies a specified condition. The specified condition may include a condition for determining whether it is necessary to adjust a correction value to correct a value detected through a distance sensor (e.g., the distance sensor (201) of FIG. 2). For example, the specified condition may be associated with an environment for performing an operation to correct the distance sensor (e.g., the distance sensor (201) of FIG. 2). For example, the specified condition may be set differently for each first sensor information obtained through a plurality of regions included in the distance sensor (e.g., the distance sensor (201) of FIG. 2). The operation of the electronic device (e.g., the electronic device (101) of FIG. 1) determining the specified condition may be associated with the operation illustrated in FIG. 16 and FIG. 17. This will be described in detail with reference to FIG. 16 and FIG. 17.

[0123] An electronic device according to one embodiment (e.g., the electronic device (101) of FIG. 1) may perform the operation 1110 of acquiring the first sensor information again based on the result of judgment in operation 1120 that the first sensor information deviates from the specified condition. For example, if the first sensor information deviates from the specified condition, the electronic device (e.g., the electronic device (101) of FIG. 1) may acquire the sensor information again based on a correction value stored in a memory (e.g., the memory (130) of FIG. 1).

[0124] An electronic device according to one embodiment (e.g., the electronic device (101) of FIG. 1) may determine a weight related to a correction value based on the first sensor information in operation 1130, based on the first sensor information satisfying a specified condition as a result of judgment in operation 1120. For example, the weight may include a parameter that adjusts a correction value that corrects a first crosstalk signal value (e.g., the first crosstalk signal value (1010) of FIG. 10) stored in a memory (e.g., the memory (130) of FIG. 1). For example, the electronic device (e.g., the electronic device (101) of FIG. 1) may determine the weight based on the first crosstalk signal value (e.g., the first crosstalk signal value (1010) of FIG. 10)) and the first signal (1002). The operation 1130 in which the electronic device (e.g., the electronic device (101) of FIG. 1) determines the weight may be associated with the example shown in FIG. 15. This will be explained in detail with reference to Fig. 15.

[0125] An electronic device according to one embodiment (e.g., the electronic device (101) of FIG. 1) can, in operation 1140, adjust a correction value stored in a memory (e.g., the memory (130) of FIG. 1) based on a weight determined in operation 1130 to a value that corrects a second interference signal value (e.g., the second interference signal value (1020) of FIG. 10) that is different from a first interference signal value (e.g., the first interference signal value (1010) of FIG. 10). For example, the electronic device (e.g., the electronic device (101) of FIG. 1) can obtain an adjusted correction value that corrects the second interference signal value (e.g., the second interference signal value (1020) of FIG. 10) through an operation of multiplying the first interference signal value (e.g., the first interference signal value (1010) of FIG. 10) by a determined weight. For example, an electronic device (e.g., the electronic device (101) of FIG. 1) can store the adjusted correction value in memory (e.g., the memory (130) of FIG. 1).

[0126] An electronic device according to one embodiment (e.g., the electronic device (101) of FIG. 1) can obtain second sensor information by correcting a second signal obtained from a distance sensor (e.g., the distance sensor (201) of FIG. 2) based on a correction value adjusted in operation 1140 in operation 1150. For example, the second sensor information may include a signal corrected based on a correction value that corrects a second crosstalk signal value (e.g., the second crosstalk signal value (1020) of FIG. 10)) from a second signal obtained from a distance sensor (e.g., the distance sensor (201) of FIG. 2).

[0127] FIG. 12 illustrates the result of calculating a correction value of a distance sensor according to one embodiment of the present disclosure.

[0128] The horizontal and vertical axes of the histogram shown in FIG. 12 may correspond to the horizontal and vertical axes of the histogram in FIG. 7.

[0129] According to one embodiment, data (1201, 1202) illustrates the result of calculating a crosstalk signal value that needs to be corrected in order to perform calibration of a distance sensor (e.g., distance sensor (201) of FIG. 2) in a specific environment. For example, the crosstalk signal value (1210) of the first data (1201) illustrates the result obtained when a specified condition for performing calibration of the distance sensor (e.g., distance sensor (201) of FIG. 2) is satisfied. For example, the crosstalk signal value (1220, 1230) of the second data (1202) illustrates the result calculated when a specified condition for performing calibration of the distance sensor (e.g., distance sensor (201) of FIG. 2) is not met. For example, cases where the specified conditions for performing calibration of the distance sensor (e.g., the distance sensor (201) of FIG. 2) are not met may include cases where an external object (e.g., the external object (750) of FIG. 7) is present within a threshold distance from the distance sensor (e.g., the distance sensor (201) of FIG. 2). For example, cases where the specified conditions for performing calibration of the distance sensor (e.g., the distance sensor (201) of FIG. 2) are not met may include cases where an external object (e.g., the external object (750) of FIG. 7) is present within 50 cm of the distance sensor (e.g., the distance sensor (201) of FIG. 2).

[0130] According to one embodiment, when the specified conditions for performing calibration of a distance sensor (e.g., distance sensor (201) of FIG. 2) are not met, an electronic device (e.g., electronic device (101) of FIG. 1) may obtain data (1202) containing errors. For example, when the specified conditions for performing calibration of a distance sensor (e.g., distance sensor (201) of FIG. 2) are not met, the electronic device (e.g., electronic device (101) of FIG. 1) may obtain data (1202) containing unnecessary crosstalk signal values ​​(1230), unlike the data (1201) obtained when the specified conditions are met.

[0131] According to one embodiment, when correcting a signal (e.g., a first signal (e.g., a first signal (1002) in FIG. 10)) obtained through a distance sensor (e.g., a distance sensor (201) in FIG. 2) based on data (1202) containing errors, a signal associated with the distance of an external object (e.g., an external object (750) in FIG. 7) for which distance information is to be obtained may be removed together due to an unnecessary crosstalk signal value (1230). For example, when correcting a signal (e.g., a first signal (e.g., a first signal (1002) in FIG. 10)) obtained through a distance sensor (e.g., a distance sensor (201) in FIG. 2) based on data (1202) containing errors, a signal obtained based on light reflected and received by an external object (e.g., an external object (750) in FIG. 7) may be removed.

[0132] FIG. 13 illustrates a flowchart of an operation in which an electronic device according to one embodiment of the present disclosure determines whether specified conditions are satisfied.

[0133] Operations 1310 to 1320 of FIG. 13 may correspond to operation 1120 of FIG. 11.

[0134] Referring to FIG. 13, an electronic device according to one embodiment (e.g., the electronic device (101) of FIG. 1) can determine whether the first information obtained through the first region satisfies the first condition in operation 1310.

[0135] An electronic device according to one embodiment (e.g., the electronic device (101) of FIG. 1) may perform operation 1110 of FIG. 11 based on the fact that, in operation 1310, the first information obtained through the first area deviates from the first condition. For example, the electronic device (e.g., the electronic device (101) of FIG. 1) may perform an operation of obtaining sensor information based on a correction value stored in a memory (e.g., the memory (130) of FIG. 1) based on the fact that, in operation 1310, the first information obtained through the first area deviates from the first condition.

[0136] An electronic device according to one embodiment (e.g., the electronic device (101) of FIG. 1) can determine whether second information satisfies a second condition in operation 1320 based on whether first information obtained through a first region in operation 1310 satisfies a first condition.

[0137] An electronic device according to one embodiment (e.g., the electronic device (101) of FIG. 1) may perform operation 1110 of FIG. 11 based on the second information deviating from the second condition in operation 1320. For example, the electronic device (e.g., the electronic device (101) of FIG. 1) may perform an operation of acquiring sensor information based on a correction value stored in a memory (e.g., the memory (130) of FIG. 1) based on the determination that the second information acquired through the second area deviated from the second condition in operation 1320.

[0138] An electronic device according to one embodiment (e.g., the electronic device (101) of FIG. 1) can perform operation 1130 of FIG. 11 based on the second information satisfying the second condition in operation 1320. For example, the electronic device (e.g., the electronic device (101) of FIG. 1) can perform an operation of determining a weight related to a correction value based on first sensor information based on the second information satisfying the second condition in operation 1320.

[0139] In the present disclosure, the "first region" may include at least one of a plurality of regions included in a light receiving unit (e.g., the light receiving unit (220) of FIG. 2). For example, the first region of the light receiving unit (e.g., the light receiving unit (220) of FIG. 2) may include a region of the light receiving unit (e.g., the light receiving unit (220) of FIG. 2) set to identify a change in a crosstalk signal value.

[0140] In the present disclosure, the "second region" may include a plurality of regions excluding the "first region" among a plurality of regions included in a light receiving unit (e.g., the light receiving unit (220) of FIG. 2). For example, the second region of the light receiving unit (e.g., the light receiving unit (220) of FIG. 2) may include a region of the light receiving unit (e.g., the light receiving unit (220) of FIG. 2) set to acquire distance information. The second region may further include a first region.

[0141] In the present disclosure, "first information" may be referred to as a term meaning information obtained through a first area of ​​a light receiving unit (e.g., the light receiving unit (220) of FIG. 2). For example, the first information may include information obtained through a first area of ​​the light receiving unit (e.g., the light receiving unit (220) of FIG. 2) among the information included in the first sensor information. For example, the first information may include information obtained based on light detected through a first area of ​​the light receiving unit (e.g., the light receiving unit (220) of FIG. 2). For example, the first information may include distance information obtained based on light detected through a first area of ​​the light receiving unit (e.g., the light receiving unit (220) of FIG. 2). For example, the first information may include illuminance information obtained based on light detected through a first area of ​​the light receiving unit (e.g., the light receiving unit (220) of FIG. 2). For example, the first information may include reliability information obtained based on light detected through a first area of ​​a light receiving unit (e.g., the light receiving unit (220) of FIG. 2). For example, the first information may include a crosstalk signal value obtained based on light detected through a first area of ​​a light receiving unit (e.g., the light receiving unit (220) of FIG. 2).

[0142] In the present disclosure, "second information" may be referred to as a term meaning information obtained through a second area of ​​a light receiving unit (e.g., the light receiving unit (220) of FIG. 2). For example, the second information may include information obtained through a second area of ​​the light receiving unit (e.g., the light receiving unit (220) of FIG. 2) among the information included in the first sensor information. For example, the second information may include information obtained based on light detected through a second area of ​​the light receiving unit (e.g., the light receiving unit (220) of FIG. 2). For example, the second information may include distance information obtained based on light detected through a second area of ​​the light receiving unit (e.g., the light receiving unit (220) of FIG. 2). For example, the second information may include illuminance information obtained based on light detected through a second area of ​​the light receiving unit (e.g., the light receiving unit (220) of FIG. 2). For example, the second information may include reliability information obtained based on light detected through a second area of ​​a light receiving unit (e.g., the light receiving unit (220) of FIG. 2). For example, the second information may include information related to a crosstalk signal value obtained based on light detected through a second area of ​​a light receiving unit (e.g., the light receiving unit (220) of FIG. 2).

[0143] In the present disclosure, "first condition" may be referred to as a term meaning whether first information obtained based on light detected through a first region of a light receiving unit (e.g., the light receiving unit (220) of FIG. 2) is included within a set threshold value. The operation of an electronic device (e.g., the electronic device (101) of FIG. 1) determining the first condition may be associated with the operation of the electronic device (e.g., the electronic device (101) of FIG. 1) illustrated in FIG. 16. This will be explained in detail with reference to FIG. 16.

[0144] In the present disclosure, "second condition" may be referred to as a term meaning whether second information obtained based on light detected through a second region of a light receiving unit (e.g., the light receiving unit (220) of FIG. 2) is included within a set threshold value. The operation of an electronic device (e.g., the electronic device (101) of FIG. 1) determining the second condition may be associated with the operation of the electronic device (e.g., the electronic device (101) of FIG. 1) illustrated in FIG. 17. This will be explained in detail with reference to FIG. 17.

[0145] FIG. 14 illustrates an example of distance information obtained for each distance sensor area of ​​an electronic device according to one embodiment of the present disclosure.

[0146] The electronic device (1401) of FIG. 14 may correspond to the electronic device (101) of FIG. 1, the electronic device (400) of FIG. 4, or the electronic device (901) of FIG. 9.

[0147] Referring to FIG. 14, an electronic device (1401) according to one embodiment may include a distance sensor (1410) positioned adjacent to at least one camera (1431, 1432, 1433, 1434).

[0148] An electronic device (1401) according to one embodiment may include a distance sensor (1410) in which the zone of the light receiving unit (e.g., the light receiving unit (220) of FIG. 2) is divided into a plurality of zones. For example, the zone of the light receiving unit (e.g., the light receiving unit (220) of FIG. 2) may include a plurality of physically separated zones. For example, the zone of the light receiving unit (e.g., the light receiving unit (220) of FIG. 2) may be divided into 64 zones, but the number of separated zones is not limited thereto.

[0149] An electronic device (1401) according to one embodiment can obtain distance information (1420) based on light detected through each of a plurality of regions of a light receiving unit (e.g., the light receiving unit (220) of FIG. 2). Each data included in the distance information (1420) of FIG. 14 may correspond to a distance value obtained based on light detected through each of the plurality of regions of the light receiving unit (e.g., the light receiving unit (220) of FIG. 2). For example, the distance information (1420) may include distance values ​​corresponding to each of the plurality of regions within the light receiving unit (e.g., the light receiving unit (220) of FIG. 2). For example, the distance information (1420) may store 64 distance values, but the distance values ​​that can be stored in the distance information (1420) are not limited as shown in FIG. 14.

[0150] An electronic device (1401) according to one embodiment may select at least one of a plurality of regions of a light receiving unit (e.g., the light receiving unit (220) of FIG. 2) as a first region (1413). For example, the electronic device (1401) may select the first region (1413) from at least one region (1411, 1412, 1413, 1414) among the plurality of regions that does not acquire distance information. For example, the first region may include a region for monitoring changes in crosstalk signal values. For example, the electronic device (1401) may select the region with the lowest reliability of distance measurement among the plurality of regions of the light receiving unit (e.g., the light receiving unit (220) of FIG. 2) as the first region (1413). For example, the electronic device (1401) may select the area furthest apart from at least one camera (1431, 1432, 1433, 1434) among the plurality of areas as the first area (1413).

[0151] FIG. 14 illustrates an example in which an electronic device (1401) according to one embodiment selects one of a plurality of regions as a first region (1413), but the method of selection, number, and location of the "first region" are not limited thereto. For example, the "first region" may be set during the manufacture of a distance sensor (e.g., the distance sensor (201) of FIG. 2). For example, the "first region" may include a plurality of regions. For example, the "first region" may include a region positioned closest to at least one camera (1431, 1432, 1433, 1434) among a plurality of regions of a light receiving unit (e.g., the light receiving unit (220) of FIG. 2). For example, the "first region" may include a region belonging to a separate module (e.g., an IC circuit) other than the light receiving unit (e.g., the light receiving unit (220) of FIG. 2). At this time, a separate module including the first area may provide a function for monitoring changes in the interference signal value.

[0152] FIG. 15 illustrates an example of a difference value obtained by an electronic device according to one embodiment of the present disclosure.

[0153] The horizontal and vertical axes of the histogram shown in FIG. 15 may correspond to the horizontal and vertical axes of the histogram in FIG. 7.

[0154] Referring to FIG. 15, data (1501) acquired by an electronic device according to one embodiment (e.g., the electronic device (101) of FIG. 1) may represent the result of comparing a peak signal (1520) within a first signal with a first crosstalk signal value (1510). In the present disclosure, the "peak signal" of a specific signal may be referred to as a term including a signal having the largest value within a specific signal. For example, the peak signal (1520) within the first signal may indicate a crosstalk signal included in the first sensor information acquired through a distance sensor (e.g., the distance sensor (201) of FIG. 2) by performing operation 1110 of FIG. 11. For example, the first crosstalk signal value (1510) within the data (1501) may correspond to the first crosstalk signal value (760) of FIG. 7.

[0155] The difference value (1540) of the data (1502) acquired by an electronic device according to one embodiment (e.g., the electronic device (101) of FIG. 1) may indicate the difference (1530) between the peak signal (1520) in the first signal and the first crosstalk signal value (1510). For example, the difference value (1540) may correspond to a signal in which a portion of the peak signal (1520) in the first signal is corrected through a correction value in which the electronic device (e.g., the electronic device (101) of FIG. 1) corrects the first crosstalk signal value (1510).

[0156] An electronic device according to one embodiment (e.g., the electronic device (101) of FIG. 1) can calculate a weight associated with a correction value based on a first interference signal value (1510) and a difference value (1540). The operation of the electronic device (e.g., the electronic device (101) of FIG. 1) determining the weight may be associated with the operation 1130 of FIG. 11. For example, the electronic device (e.g., the electronic device (101) of FIG. 1) can calculate a weight for calculating a correction value corresponding to a second interference signal value based on the first interference signal value and the difference value (1540). For example, the electronic device (e.g., the electronic device (101) of FIG. 1) can calculate the weight through an operation such as Equation 1 below.

[0157]

[0158] An electronic device according to one embodiment (e.g., the electronic device (101) of FIG. 1) can adjust a correction value stored in a memory (e.g., the memory (130) of FIG. 1) based on a calculated weight to a correction value that corrects a second crosstalk signal value. The operation of the electronic device (e.g., the electronic device (101) of FIG. 1) adjusting the correction value may be associated with the operation 1140 of FIG. 11. For example, the electronic device (e.g., the electronic device (101) of FIG. 1) can determine the second crosstalk signal value through an operation such as Equation 2 below.

[0159]

[0160] For example, an electronic device (e.g., the electronic device (101) of FIG. 1) can adjust a correction value stored in a memory (e.g., the memory (130) of FIG. 1) to a correction value that corrects a determined second crosstalk signal value.

[0161] FIG. 16 illustrates a flowchart of an operation in which an electronic device according to one embodiment of the present disclosure determines a first condition.

[0162] Operations 1610 to 1670 in the flowchart (1600) of FIG. 16 may be included in operation 1120 of FIG. 11. Operations 1610 to 1670 in the flowchart (1600) of FIG. 16 may correspond to operation 1310 of FIG. 13. The flowchart (1600) illustrated in FIG. 16 illustrates an example for explaining a method for an electronic device (e.g., the electronic device (101) of FIG. 1) to determine whether a first condition is satisfied in one embodiment, and the detailed conditions for determining whether the first condition is satisfied in one embodiment may be changed from the example illustrated in FIG. 16.

[0163] Referring to FIG. 16, an electronic device according to one embodiment (e.g., the electronic device (101) of FIG. 1) can determine, in operation 1610, whether the difference between a reference value stored in a memory (e.g., the memory (130) of FIG. 1) and a peak signal within a first signal (e.g., the peak signal (1520) of FIG. 15) is greater than or equal to a first threshold value. The 'reference value' stored in the memory (e.g., the memory (130) of FIG. 1) may refer to a peak signal within a signal obtained by the electronic device (e.g., the electronic device (101) of FIG. 1) through a first area (e.g., the first area (1413) of FIG. 14) of a distance sensor (e.g., the distance sensor (201) of FIG. 2) during calibration of a distance sensor (e.g., the distance sensor (201) of FIG. 2) that has already been performed. For example, the reference value may correspond to a calibration value adjusted according to the previously performed operation 1140 when the electronic device (e.g., the electronic device (101) of FIG. 1) repeatedly performs operations 1110 to 1150 of FIG. 11. This will be described later in connection with operation 1920 of FIG. 19. For example, the first threshold value may be set to a positive value. For example, operation 1610 may be understood as an operation to identify whether the crosstalk signal value obtained through the first area (e.g., the first area (1413) of FIG. 14) has changed by a certain amount in the negative direction. For example, if the difference between a reference value stored in a memory (e.g., memory (130) of FIG. 1) and a peak signal within a first signal (e.g., peak signal (1520) of FIG. 15) is greater than or equal to a first threshold value, an electronic device (e.g., electronic device (101) of FIG. 1) can identify that the crosstalk signal value obtained through a first region (e.g., first region (1413) of FIG. 14) has changed in a negative direction.

[0164] An electronic device according to one embodiment (e.g., the electronic device (101) of FIG. 1) may, in operation 1620, set a correction value to a specified initial setting value based on the fact that in operation 1610, the difference between a reference value stored in memory (e.g., the memory (130) of FIG. 1) and a peak signal in a first signal (e.g., the peak signal (1520) in FIG. 15) is greater than or equal to a first threshold value. For example, the specified initial setting value may include a process correction value applied during the manufacture of the electronic device (e.g., the electronic device (101) of FIG. 1) or the lowest crosstalk signal value in process dispersion data. For example, in operation 1620, the operation of setting the correction value to a specified initial setting value may be understood as an operation to prevent unintended excessive correction.

[0165] An electronic device according to one embodiment (e.g., the electronic device (101) of FIG. 1) in operation 1630,

[0166] Based on determining that the difference between a reference value stored in memory (e.g., memory (130) in FIG. 1) and a peak signal within a first signal (e.g., peak signal (1520) in FIG. 15) in operation 1610 is less than a first threshold, it can be determined whether the intensity of light of a designated band detected through a first region is less than a second threshold. For example, operation 1620 can be understood as an operation that determines conditions related to illuminance by a light source outside an electronic device (e.g., electronic device (101) in FIG. 1). For example, the electronic device (e.g., electronic device (101) in FIG. 1) can determine whether the intensity of light of a designated band (e.g., infrared) obtained through a first region (e.g., first region (1413) in FIG. 14) within a light receiving unit (e.g., light receiving unit (220) in FIG. 2) is less than a second threshold. For example, the second threshold may include, but is not limited to, 35 kcps. For example, the second threshold may be set to a different value depending on the shape of the electronic device (e.g., the electronic device (101) of FIG. 1) or the performance, placement, or shape of the distance sensor (e.g., the distance sensor (201) of FIG. 2).

[0167] An electronic device according to one embodiment (e.g., the electronic device (101) of FIG. 1) can determine, in operation 1640, whether the distance calculated through the first region is less than a third threshold value. For example, operation 1640 can be understood as an operation to determine whether the distance information obtained through the distance sensor (e.g., the distance sensor (201) of FIG. 2) includes a crosstalk signal from a window (e.g., the window (530) of FIG. 5) or a cover (e.g., the cover (911) of FIG. 9) coupled to the distance sensor (e.g., the distance sensor (201) of FIG. 2). For example, if the distance calculated through the first area (e.g., the first area (1413) in FIG. 14) is within 50 mm under conditions where an external object (e.g., external object (750) in FIG. 7) is located at a distance (e.g., 2 m), it may mean that a crosstalk signal is included by a window (e.g., window (530) in FIG. 5) or a cover (e.g., cover (911) in FIG. 9). For example, the third threshold value may include, but is not limited to, 50 mm. For example, the third threshold value may be set to a different value depending on the shape of the electronic device (e.g., electronic device (101) in FIG. 1), or the performance, placement, or shape of the distance sensor (e.g., distance sensor (201) in FIG. 2).

[0168] An electronic device according to one embodiment (e.g., the electronic device (101) of FIG. 1) can determine, in operation 1650, whether a peak signal (e.g., the peak signal (1520) in the first signal of FIG. 15) in the first signal obtained through a first region is less than a fourth threshold value. For example, operation 1650 can be understood as an operation to identify when an external object (e.g., the external object (750) of FIG. 7) exists within a third threshold value (e.g., 50 mm) from a distance sensor (e.g., the distance sensor (201) of FIG. 2). Operation 1650 can be understood as performing an operation corresponding to operation 1730 of FIG. 17 with respect to the first signal obtained through the first region, and will be described later to avoid redundant explanation.

[0169] An electronic device according to one embodiment (e.g., the electronic device (101) of FIG. 1) can determine, in operation 1660, whether the reliability of distance information calculated through a first region is below a fifth threshold. The reliability may correspond to the reliability described above with reference to FIG. 10. For example, the electronic device (e.g., the electronic device (101) of FIG. 1) can determine whether the reliability is below the fifth threshold based on a reliability level.

[0170] For example, operation 1660 can be understood as an operation to identify when a black external object is present within a third threshold (e.g., 50 mm) from a distance sensor (e.g., distance sensor (201) of FIG. 2). For example, when a black external object is present within a third threshold (e.g., 50 mm) from a distance sensor (e.g., distance sensor (201) of FIG. 2), the black external object absorbs light of a designated band (e.g., infrared) output from a light-emitting unit (e.g., light-emitting unit (210) of FIG. 2), so that a signal corresponding to light reflected from an external object located relatively far away (e.g., external object (750) of FIG. 7) among the sensor information (e.g., flight-time histogram) obtained from the distance sensor (e.g., distance sensor (201) of FIG. 2) may not be detected. For example, if a black external object is present within a third threshold (e.g., 50 mm) from a distance sensor (e.g., distance sensor (201) of FIG. 2), distance information calculated based on light reflected from the black external object located within the third threshold (e.g., 50 mm) can be obtained. In this case, the distance sensor (e.g., distance sensor (201) of FIG. 2) detects light reflected from the black external object within a third threshold (e.g., 50 mm) from the distance (e.g., distance sensor (201) of FIG. 2), but fails to detect light reflected from an external object located at a relatively far distance (e.g., external object (750) of FIG. 7), so the SNR may be measured as relatively high.If there is no black external object within a third threshold value (e.g., 50 mm) from a distance sensor (e.g., distance sensor (201) of FIG. 2), a signal corresponding to light reflected from an external object located at a relatively distant distance (e.g., external object (750) of FIG. 7), a signal corresponding to reflected light (e.g., reflected light (742) of FIG. 7) reflected by a window (e.g., window (740) of FIG. 7), or a signal due to reflected light reflected by a cover (e.g., cover (911) of FIG. 9) may be detected together. In this case, the signal corresponding to the reflected light (e.g., reflected light (742) of FIG. 7) reflected by the window (e.g., window (740) of FIG. 7) or the signal due to the reflected light reflected by the cover (e.g., cover (911) of FIG. 9) may be measured as lower than when a black external object is located within a third threshold value (e.g., 50 mm) from the distance (e.g., distance sensor (201) of FIG. 2) due to the signal corresponding to the light reflected from an external object located at a relatively distant distance (e.g., external object (750) of FIG. 7). Here, the measurement of a relatively low SNR may correspond to the measurement of a relatively low reliability of the distance information.

[0171] An electronic device according to one embodiment (e.g., the electronic device (101) of FIG. 1) can determine, in operation 1670, whether the absolute value of the difference between a reference value stored in memory (e.g., memory (130) of FIG. 1) and a peak signal within a first signal (e.g., the peak signal (1520) within a first signal in FIG. 15) is greater than or equal to a sixth threshold value. For example, operation 1670 can be understood as an operation determining whether there is a change in the crosstalk signal value obtained through a first area (e.g., the first area (1413) of FIG. 14). The 'reference value' in operation 1670 may correspond to the reference value mentioned in operation 1610. The peak signal within the first signal (e.g., the peak signal (1520) within a first signal in FIG. 15) is obtained through a first area (e.g., the first area (1413) of FIG. 14)) and may include a crosstalk signal to which a correction value has not been applied. For example, an electronic device (e.g., the electronic device (101) of FIG. 1) can identify that the crosstalk signal value has changed based on the fact that, in operation 1670, the absolute value of the difference between the reference value stored in memory (e.g., the memory (130) of FIG. 1) and the peak signal in the first signal (e.g., the peak signal (1520) in FIG. 15) is greater than or equal to the sixth threshold value.

[0172] An electronic device according to one embodiment (e.g., the electronic device (101) of FIG. 1) may perform operation 1320 of FIG. 13 based on the fact that in operation 1670, the absolute value of the difference between a reference value stored in memory (e.g., the memory (130) of FIG. 1) and a peak signal within a first signal (e.g., the peak signal (1520) within the first signal of FIG. 15) is greater than or equal to a sixth threshold value. For example, the electronic device (e.g., the electronic device (101) of FIG. 1) may perform an operation (e.g., operation 1320 of FIG. 13) of determining whether the second information described with reference to FIG. 13 satisfies the second condition based on the judgment result of operation 1670 being determined to satisfy ('yes').

[0173] An electronic device according to one embodiment (e.g., the electronic device (101) of FIG. 1) may store the value of the peak signal (e.g., the peak signal (1520) of FIG. 1) in the memory (e.g., the memory (130) of FIG. 1) in the first signal in operation 1670, based on determining that the absolute value of the difference between the reference value stored in the memory (e.g., the memory (130) of FIG. 1) and the value of the peak signal (e.g., the peak signal (1520) of FIG. 1) in the first signal is greater than or equal to the sixth threshold value. The value of the peak signal within the first signal (e.g., the peak signal within the first signal of FIG. 15 (1520)) stored in the memory (e.g., the memory (130) of FIG. 1) can be used as a 'reference value' when the electronic device (e.g., the electronic device (101) of FIG. 1) performs operations 1610 and 1670 of FIG. 16 for calibration of a subsequent distance sensor (e.g., the distance sensor (201) of FIG. 2). For example, the value of the peak signal within the first signal (e.g., the peak signal within the first signal of FIG. 15 (1520)) stored in the memory (e.g., the memory (130) of FIG. 1) can be set as a 'reference value' used in operations 1610 and 1670 of FIG. 16 as long as certain conditions are satisfied. The operation of setting the value of the peak signal (e.g., the peak signal (1520) in the first signal of FIG. 15) within the first signal stored in the memory (e.g., the memory (130) of FIG. 1) as a reference value may be associated with the operation 1920 of FIG. 19 to be described later.

[0174] An electronic device according to one embodiment (e.g., the electronic device (101) of FIG. 1) can perform operation 1110 of FIG. 11 based on deviating from each condition in operations 1610 to 1670. For example, the electronic device (e.g., the electronic device (101) of FIG. 1) can perform an operation of reacquiring sensor information based on a correction value stored in a memory (e.g., the memory (130) of FIG. 1) based on deviating from each condition in operations 1610 to 1670.

[0175] The sequence of operations 1610 to 1670 performed by an electronic device according to one embodiment in FIG. 16 (e.g., the electronic device (101) of FIG. 1) is not limited to that shown in FIG. 16. Additionally, some of the operations performed by the electronic device according to one embodiment in FIG. 16 (e.g., the electronic device (101) of FIG. 1) may be omitted or new operations may be added.

[0176] FIG. 17 illustrates a flowchart of an operation in which an electronic device according to one embodiment of the present disclosure determines a second condition.

[0177] Operations 1710 to 1750 of FIG. 17 may be included in operation 1120 of FIG. 11. Operations 1710 to 1750 of FIG. 17 may correspond to operation 1320 of FIG. 13. For example, operations 1710 to 1750 of FIG. 17 may correspond to an operation of determining whether second information among sensor information satisfies a second condition among specified conditions. The flowchart illustrated in FIG. 17 illustrates an example for explaining a method in which an electronic device (e.g., the electronic device (101) of FIG. 1) determines whether the second condition is satisfied in one embodiment, and the detailed conditions for determining whether the second condition is satisfied in one embodiment may be changed from the example illustrated in FIG. 17.

[0178] Referring to FIG. 17, an electronic device according to one embodiment (e.g., the electronic device (101) of FIG. 1) may determine, in operation 1710, whether the intensity of light of a designated band detected through a second region is less than a second threshold. For example, operation 1710 may be understood as an operation that determines conditions related to illuminance by a light source outside the electronic device (e.g., the electronic device (101) of FIG. 1). For example, the electronic device (e.g., the electronic device (101) of FIG. 1) may determine whether the intensity of light of a designated band (e.g., infrared) obtained through a second region different from a first region (e.g., the first region (1413) of FIG. 14) within a light receiving unit (e.g., the light receiving unit (220) of FIG. 2) is less than a second threshold. Operation 1710 may be understood as performing an operation corresponding to operation 1630 of FIG. 16 with respect to the second information.

[0179] An electronic device according to one embodiment (e.g., the electronic device (101) of FIG. 1) can determine, in operation 1720, whether the distance calculated through the first region is less than the third threshold value. Operation 1720 can be understood as performing an operation corresponding to operation 1640 with respect to second information obtained through the second region.

[0180] An electronic device according to one embodiment (e.g., the electronic device (101) of FIG. 1) can determine, in operation 1730, whether a peak signal in a first signal obtained through a second region (e.g., the peak signal (1520) in FIG. 15) in the first signal is less than a fourth threshold value. For example, operation 1730 can be understood as an operation to identify when an external object (e.g., the external object (750) of FIG. 7) is present within a third threshold value (e.g., 50 mm) from a distance sensor (e.g., the distance sensor (201) of FIG. 2). For example, when an external object (e.g., external object (750) in Fig. 7) is present within a third threshold (e.g., 50 mm) from a distance sensor (e.g., distance sensor (201) in Fig. 2), the peak signal in the first signal (e.g., peak signal (1520) in the first signal in Fig. 15) may be relatively larger than when no external object is present within a third threshold (e.g., 50 mm) from a distance sensor (e.g., distance sensor (201) in Fig. 2). For example, Table 2 below is an example of an experimental result in which the peak signal in the first signal (e.g., peak signal (1520) in the first signal in Fig. 15) obtained through a second region exceeds a fourth threshold when an external object (e.g., external object (750) in Fig. 7) is present within a third threshold (e.g., 50 mm) from a distance sensor (e.g., distance sensor (201) in Fig. 2).

[0181] [Table 2]

[0182]

[0183] For example, the fourth threshold may be set to 1200 kcps, but is not limited thereto. For example, the fourth threshold may be set differently depending on the shape of the electronic device (e.g., the electronic device (101) of FIG. 1) or the performance, placement, or shape of the distance sensor (e.g., the distance sensor (201) of FIG. 2).

[0184] An electronic device according to one embodiment (e.g., the electronic device (101) of FIG. 1) can determine, in operation 1740, whether the reliability of distance information calculated through a second area is less than or equal to a fifth threshold. Operation 1740 can be understood as an operation that performs a determination corresponding to operation 1660 of FIG. 16 with respect to second information obtained through a second area.

[0185] An electronic device according to one embodiment (e.g., the electronic device (101) of FIG. 1) can determine, in operation 1750, whether light of a periodically specified band (e.g., infrared) is detected by an illuminance sensor (e.g., the illuminance sensor (430) of FIG. 4). For example, operation 1750 can be understood as an operation that identifies when an external object (e.g., the external object (750) of FIG. 7) is present within a predetermined distance from a distance sensor (e.g., the distance sensor (421) of FIG. 2). For example, when an external object (e.g., external object (750) of FIG. 7) is present within a predetermined distance from a distance sensor (e.g., distance sensor (421) of FIG. 2), an illuminance sensor (e.g., illuminance sensor (430) of FIG. 4) positioned adjacent to the distance sensor (e.g., distance sensor (421) of FIG. 4) can periodically detect light of a designated band emitted from a light-emitting unit (e.g., light-emitting unit (210) of FIG. 2) and reflected by the external object (e.g., external object (750) of FIG. 7) within a predetermined distance from the distance sensor (e.g., distance sensor (421) of FIG. 2). Operation 1750 may be associated with an example illustrated in FIG. 18. This will be explained in detail with reference to FIG. 18. According to one embodiment, an electronic device (e.g., the electronic device (101) of FIG. 1) may perform operation 1130 of FIG. 11 by determining that there is no external object (e.g., external object (750) of FIG. 7) within a predetermined distance from a distance sensor (e.g., the distance sensor (421) of FIG. 2) based on the fact that light of a periodically specified band (e.g., infrared) is not detected by an illuminance sensor (e.g., the illuminance sensor (430) of FIG. 4) in operation 1750.

[0186] An electronic device according to one embodiment (e.g., the electronic device (101) of FIG. 1) may perform operation 1110 of FIG. 11 based on each condition being not satisfied in operations 1710 to 1750. For example, the electronic device (e.g., the electronic device (101) of FIG. 1) may perform an operation of reacquiring sensor information based on a correction value stored in a memory (e.g., the memory (130) of FIG. 1) based on each condition not being satisfied in operations 1710 to 1750.

[0187] The sequence of operations 1710 to 1750 performed by an electronic device according to one embodiment in FIG. 17 (e.g., the electronic device (101) of FIG. 1) is not limited to that shown in FIG. 17. Additionally, some of the operations performed by the electronic device according to one embodiment in FIG. 17 (e.g., the electronic device (101) of FIG. 1) may be omitted or new operations may be added.

[0188] FIG. 18 illustrates an example of the result of an electronic device according to one embodiment of the present disclosure detecting light of a specified band through an illuminance sensor.

[0189] According to one embodiment, an illuminance sensor (e.g., the illuminance sensor (430) of FIG. 4) can measure the intensity of light around an electronic device (e.g., the electronic device (101) of FIG. 1) and convert it into an electrical signal. For example, the illuminance sensor (e.g., the illuminance sensor (430) of FIG. 4) can identify the intensity of light (e.g., infrared) of a specified band and convert it into an electrical signal. The illuminance sensor (e.g., the illuminance sensor (430) of FIG. 4) may include, for example, a flicker sensor for detecting a flicker phenomenon.

[0190] The example illustrated in FIG. 18 may be associated with the operation 1750 of FIG. 17. For example, FIG. 18 may represent the result of light of a designated band (e.g., infrared) being periodically detected through an illuminance sensor (e.g., illuminance sensor (430) of FIG. 4) when an external object (e.g., external object (750) of FIG. 7) is present within a predetermined distance from a distance sensor (e.g., distance sensor (421) of FIG. 2). For example, the first region (1810) of FIG. 18 may represent the result of light of a designated band periodically emitted from a light-emitting unit (e.g., light-emitting unit (210) of FIG. 2) being reflected by an external object (e.g., external object (750) of FIG. 7) within a predetermined distance and being periodically detected by an illuminance sensor (e.g., illuminance sensor (430) of FIG. 4). For example, the second region (1820) of FIG. 18 may represent a case where light is not detected by the illuminance sensor (e.g., the illuminance sensor (430) of FIG. 4) in an environment where no external object (e.g., the external object (750) of FIG. 7) exists within a predetermined distance from the distance sensor (e.g., the distance sensor (201) of FIG. 2). The third region (1830) of FIG. 18 may represent a result where light of a designated band periodically emitted from the light-emitting part (e.g., the light-emitting part (210) of FIG. 2), similar to the first region (1810), is reflected by an external object (e.g., the external object (750) of FIG. 7) within a predetermined distance and is periodically detected by the illuminance sensor (e.g., the illuminance sensor (430) of FIG. 4).

[0191] FIG. 19 is a flowchart of an operation in which an electronic device according to one embodiment of the present disclosure determines a weight.

[0192] Operations 1910 and 1920 of FIG. 19 may be included in operation 1130 of FIG. 11.

[0193] Referring to FIG. 19, according to one embodiment, an electronic device (e.g., the electronic device (101) of FIG. 1) can manage weights stored in a memory (e.g., the memory (130) of FIG. 1). Here, the weights stored in the memory (e.g., the memory (130) of FIG. 1) may include weights having a minimum value among the weights repeatedly acquired while the electronic device (e.g., the electronic device (101) of FIG. 1) performs a series of operations to calibrate a distance sensor (e.g., the distance sensor (201) of FIG. 1) with respect to weights corresponding to each of the multiple regions within the light receiving unit (e.g., the light receiving unit (220) of FIG. 2) or weights corresponding to clustered regions. For example, operations 1910 and 1920 can be understood as operations in which an electronic device (e.g., the electronic device (101) of FIG. 1) repeatedly acquires weights, selects the weight having the minimum value among the acquired weights, and stores it in memory (e.g., the memory (130) of FIG. 1). As a result, in a series of operations for calibrating a distance sensor (e.g., the distance sensor (201) of FIG. 2), a weight in which the influence of the external environment (e.g., foreign matter) is minimally reflected can be determined as the weight for acquiring the correction value. Operations 1910 to 1920 can be performed for each of the multiple regions included in the second region within the distance sensor (e.g., the distance sensor (201) of FIG. 2). For example, an electronic device (e.g., the electronic device (101) of FIG. 1) can determine weights by clustering multiple regions within a light receiving unit (e.g., the light receiving unit (220) of FIG. 2) into multiple parts. An example of how an electronic device (e.g., the electronic device (101) of FIG. 1) determines weights by clustering multiple regions within a light receiving unit (e.g., the light receiving unit (220) of FIG. 2) into multiple parts will be explained in detail with reference to FIG. 20.

[0194] According to one embodiment, an electronic device (e.g., the electronic device (101) of FIG. 1) can determine, in operation 1910, whether a weight calculated based on a first crosstalk signal value (e.g., the first crosstalk signal value (1510) of FIG. 15) and a difference value (e.g., the difference value (1540) of FIG. 15), as described above with reference to FIG. 15, is smaller than a weight stored in a memory (e.g., the memory (130) of FIG. 1). For example, operation 1910 can be understood as an operation in which the electronic device (e.g., the electronic device (101) of FIG. 1) determines whether a recently acquired weight is smaller than weights already acquired.

[0195] According to one embodiment, an electronic device (e.g., the electronic device (101) of FIG. 1) may store a determined weight in memory in operation 1920 based on the fact that, in operation 1910, the calculated weight is smaller than the weight stored in memory (e.g., the memory (130) of FIG. 1). For example, the weight stored in memory (e.g., the memory (130) of FIG. 1) may be deleted and the determined weight may be stored in memory. The operation of storing the determined weight in memory (e.g., the memory (130) of FIG. 1) may be associated with the example illustrated in FIG. 20. This will be described in detail with reference to FIG. 20.

[0196] Although only the case where operation 1920 performs the operation of storing the calculated weight in memory is illustrated in FIG. 19, the operation performed in operation 1920 is not limited thereto. For example, it may include an operation to update the 'reference value' used in operations 1610 and 1670 of FIG. 16. For example, an electronic device (e.g., electronic device (101) of FIG. 1) may, in operation 1920, update the 'reference value' mentioned in operations 1610 and 1670 of FIG. 16 to the value of the peak signal (e.g., peak signal (1520) in the first signal of FIG. 15) in the first signal stored in memory (e.g., memory (130) of FIG. 1). The updated 'reference value' can be used as the 'reference value' for operations 1610 and 1670 of FIG. 16 when the electronic device (e.g., the electronic device (101) of FIG. 1) subsequently performs a series of operations to calibrate the distance sensor (e.g., the distance sensor (201) of FIG. 2).

[0197] According to one embodiment, an electronic device (e.g., the electronic device (101) of FIG. 1) may perform an operation (e.g., operation 1110 of FIG. 11) of reacquiring sensor information based on a correction value stored in memory (e.g., the memory (130) of FIG. 1) based on the fact that, in operation 1910, the weight determined in operation 1130 of FIG. 11 is greater than or equal to the weight stored in memory (e.g., the memory (130) of FIG. 1).

[0198] FIG. 20 illustrates an example in which an electronic device according to one embodiment of the present disclosure stores a determined weight in memory.

[0199] The example illustrated in FIG. 20 may be associated with operation 1920 and operation 1920 of FIG. 19. For example, the operation of an electronic device (e.g., electronic device (101) of FIG. 1) described with reference to FIG. 20 may be understood as an example describing the operation of an electronic device (e.g., electronic device (101) of FIG. 1) according to one embodiment repeatedly acquiring weights, selecting a weight having the minimum value among the acquired weights, and storing it in memory (e.g., memory (130) of FIG. 1).

[0200] According to one embodiment, an electronic device (e.g., the electronic device (101) of FIG. 1) may store weights (2000) associated with correction values ​​of each of a plurality of regions within a light receiving unit (e.g., the light receiving unit (220) of FIG. 2) in a region of a memory (e.g., the memory (130) of FIG. 1). The weights (2000) may be stored to correspond to each of the plurality of regions within the light receiving unit (e.g., the light receiving unit (220) of FIG. 2), and the memory space (e.g., the memory (130) of FIG. 1) and the format in which the weights (2000) are stored are not limited to the example of the weights (2000) shown in FIG. 20.

[0201] According to one embodiment, an electronic device (e.g., the electronic device (101) of FIG. 1) may maintain weights (2000) corresponding to each of a plurality of regions stored in memory (e.g., the memory (130) of FIG. 1) at a smaller value compared to calculated weights. For example, if the calculated first weights are smaller than the first weights (2010) stored in memory (e.g., the memory (130) of FIG. 1), the electronic device (e.g., the electronic device (101) of FIG. 1) may store the calculated first weights in the memory space (e.g., the memory (130) of FIG. 1) where the first weights (2010) are stored. For example, an electronic device (e.g., the electronic device (101) of FIG. 1) may retain the second weights (2020) stored in memory (e.g., the memory (130) of FIG. 1) if the second weights calculated are greater than or equal to the second weights (2020) stored in memory (e.g., the memory (130) of FIG. 1).

[0202] According to one embodiment, an electronic device (e.g., the electronic device (101) of FIG. 1) may determine weights stored in a memory (e.g., the memory (130) of FIG. 1) by clustering multiple regions within a light receiving unit (e.g., the light receiving unit (220) of FIG. 2) into multiple parts. For example, if a specified condition for a first part among multiple regions within the light receiving unit (e.g., the light receiving unit (220) of FIG. 2) is satisfied, the first weights (2010) corresponding to the first part may be updated together. For example, if the specified condition for a first part among multiple regions within the light receiving unit (e.g., the light receiving unit (220) of FIG. 2) is not met, the first weights (2010) corresponding to the first part may be maintained together. Here, the specified condition for the first part among the plurality of regions may include, but is not limited to, cases where each of the regions clustered into the first part among the plurality of regions within the light receiving unit (e.g., the light receiving unit (220) of FIG. 2) satisfies the condition for updating the weight. For example, the specified condition for the first part among the plurality of regions may include cases where a number of regions exceeding a set ratio among the regions clustered into the first part satisfies the condition for updating the weight. Furthermore, the method of clustering the plurality of regions within the light receiving unit (e.g., the light receiving unit (220) of FIG. 2) and the size of each clustered part are not limited as described above with reference to FIG. 20.

[0203] FIG. 21 illustrates an example in which an electronic device according to one embodiment of the present disclosure provides a user interface.

[0204] The electronic device (2101) of FIG. 21 may correspond to the electronic device (101) of FIG. 1, the electronic device (400) of FIG. 4, or the electronic device (901) of FIG. 9.

[0205] An electronic device (2101) according to one embodiment may provide a first user interface (UI) (2110) that guides the acquisition of first sensor information. For example, referring to FIG. 21, when it is determined that calibration of a distance sensor (e.g., distance sensor (201) of FIG. 2) is required, the first user interface (2110) that guides the acquisition of first sensor information may be displayed on a display (e.g., display module (160) of FIG. 1). For example, an electronic device (e.g., electronic device (101) of FIG. 1) may determine whether calibration of a distance sensor (e.g., distance sensor (201) of FIG. 2) is required based on driving a camera module (e.g., camera module (180) of FIG. 1). For example, an electronic device (e.g., the electronic device (101) of FIG. 1) may determine that calibration of the distance sensor (e.g., the distance sensor (201) of FIG. 2) is required when the change in the crosstalk signal value obtained through the distance sensor (e.g., the distance sensor (201) of FIG. 2) is greater than a threshold value.

[0206] An electronic device (2101) according to one embodiment may provide a second user interface (2120) that indicates that the calibration of the distance sensor (e.g., the distance sensor (201) of FIG. 2) is complete when the calibration of the distance sensor (e.g., the distance sensor (201) of FIG. 2) is complete. For example, when the calibration of the distance sensor (e.g., the distance sensor (201) of FIG. 2) is complete, text indicating that the calibration of the distance sensor (e.g., the distance sensor (201) of FIG. 2) is complete may be displayed on a display (e.g., the display module (160) of FIG. 1) as the second user interface (2120).

[0207] In FIG. 21, only an example is illustrated of displaying a user interface (2110, 2120) on a display (e.g., the display module (160) of FIG. 1) through text, but the method of providing the user interface (2110, 2120) is not limited thereto. For example, the electronic device (2101) may provide a voice that guides the acquisition of first sensor information.

[0208] FIG. 22 illustrates a flowchart of an operation in which an electronic device according to one embodiment of the present disclosure controls the calibration of a distance sensor.

[0209] According to one embodiment, an electronic device (e.g., the electronic device (101) of FIG. 1) may include a camera module (2201), a processor (2202), and a distance sensor (2203).
