Description

Technical Field

[0001] This application relates to the field of terminal technology, and in particular to a shooting method and electronic device. Background Technology

[0002] Currently, most electronic products have image capture capabilities. Generally, the image capture process involves opening the camera interface on the electronic device and then clicking the capture button to complete the shot. This method requires the user to manually press the capture button, which is not very convenient. Summary of the Invention

[0003] This application provides a shooting method and electronic device that can improve the convenience of image shooting and enhance the user experience.

[0004] In a first aspect, a shooting method is provided, applied to an electronic device, the method comprising: displaying a shooting interface, the shooting interface including a preview image, the preview image including a human object; determining that the human object in the preview image remains stationary, and starting a timer; when the timer reaches a set duration, capturing a first image.

[0005] In this embodiment of the application, the electronic device can automatically capture images, which improves the convenience of image capture. Moreover, when the electronic device determines that the person in the preview image is stationary, it starts a countdown. When the countdown reaches 0, it automatically captures the image. Since the countdown is started only when the person is stationary, it can ensure that the image is captured automatically when the subject has already adjusted the shooting posture, so as to ensure that the person in the captured image is clear, thus improving the image capture command.

[0006] In one possible design, starting a timer when it is determined that the person in the preview image remains stationary includes: starting a timer when it is determined that the person in the preview image remains stationary and the stationary duration reaches a first duration.

[0007] In this embodiment of the application, when the electronic device determines that the stillness duration of the person in the preview image has reached the first duration, it starts a countdown to take a picture, avoiding accidental start of the countdown and ensuring that the picture is taken automatically when the subject has adjusted the shooting posture, so as to ensure that the person in the picture is clear and improve the image shooting command.

[0008] In one possible design, the preview image includes N human figures. The step of starting a timer when the human figures in the preview image are stationary includes: starting a timer when M human figures out of the N human figures are stationary, wherein the ratio of M to N is greater than a first threshold; and / or, the M human figures are located at a preset position in the preview image.

[0009] In this embodiment of the application, when the electronic device determines that most of the people in the preview image remain still, it starts a countdown to take a picture, which improves the convenience of image shooting and ensures that most of the people in the captured image are clear, thus improving the image shooting command.

[0010] In one possible design, the M individual figures are located in the central area of ​​the preview image.

[0011] In this embodiment of the application, when the electronic device determines that the person in the center area of ​​the preview image remains stationary, it starts a countdown to take a picture, which improves the convenience of image shooting and ensures that the main person in the captured image is clear, thus improving the image shooting command.

[0012] In one possible design, prior to starting the timer, the method further includes determining that the number of human figures contained within the preview image remains constant.

[0013] In this embodiment of the application, when the electronic device determines that the number of people in the preview image remains unchanged, it starts a countdown to take a picture, which improves the convenience of image shooting and ensures that the people in the captured image are clear, thus improving the image shooting command.

[0014] In one possible design, determining that the number of human objects contained in the preview image remains constant includes: determining that the number of human objects in the preview image remains constant for a second duration.

[0015] In this embodiment of the application, when the electronic device determines that the number of people in the preview image remains unchanged and the duration of this unchanged period is a second duration, it starts a countdown to take a picture. This avoids accidentally starting the countdown and can ensure that the captured image is as clear as possible without any people entering or leaving the frame, thus improving the image capture efficiency.

[0016] In one possible design, before starting the timer when it is determined that the person in the preview image remains stationary, the method further includes: receiving a first operation; and in response to the first operation, entering a first mode, wherein the first operation is a mode for starting the timer after determining that the person is stationary.

[0017] In this embodiment, after the electronic device enters the first mode, it starts a countdown to take a picture when the subject is determined to be stationary. Therefore, users can decide whether to enter the first mode according to their needs, resulting in a better user experience.

[0018] In one possible design, after entering the first mode, the method further includes: displaying a first prompt message, the first prompt message being used to indicate that the first mode has been entered.

[0019] In this embodiment of the application, after the electronic device enters the first mode, it can prompt the user that it has entered the first mode, resulting in a better user experience.

[0020] In one possible design, the method further includes: receiving a second operation; and in response to the second operation, exiting the first mode and entering a second mode, wherein the second mode is a mode that starts a countdown when the shooting button is triggered.

[0021] In this embodiment, after the electronic device enters the second mode, a countdown begins for shooting when the user presses the shutter button. Therefore, the user can choose to use either the first or second mode according to their needs, resulting in a better user experience.

[0022] In one possible design, the method further includes: receiving a third operation; and in response to the third operation, setting a set duration for the timer in the first mode.

[0023] In this embodiment, after the electronic device enters the first mode, it starts a countdown to take a picture when the subject is determined to be stationary. Therefore, users can decide whether to enter the first mode according to their needs, resulting in a better user experience. Furthermore, the countdown duration in the first mode can be set by the user, further enhancing the user experience.

[0024] In one possible design, the timer's set duration in the first mode is the default duration.

[0025] In this embodiment, after the electronic device enters the first mode, it starts a countdown to take a picture when the subject is determined to be stationary. Therefore, users can decide whether to enter the first mode according to their needs, resulting in a better user experience. Moreover, the countdown duration in the first mode can be a default duration, eliminating the need for users to set it manually, thus offering good convenience.

[0026] In one possible design, the electronic device includes a first screen and a second screen, the first screen being located on the front of the electronic device and the second screen being located on the back of the electronic device. Before starting the timer when it is determined that the person in the preview image remains stationary, the device further includes: determining that the shooting interface is displayed on the second screen.

[0027] In this embodiment, when the rear display screen of the electronic device enters the shooting interface, it can automatically enter the first mode for shooting, that is, when the person is determined to be stationary, a countdown is started to take the picture. This automatic entry into the first mode is highly convenient.

[0028] In one possible design, the second screen is smaller than the first screen.

[0029] In this embodiment, because the rear display screen of the electronic device is relatively small, it can automatically enter the first mode for shooting when the rear display screen enters the shooting interface. That is, it starts a countdown to shoot when the subject is determined to be stationary. This automatic entry into the first mode is highly convenient.

[0030] In one possible design, the shooting interface does not include a shooting button.

[0031] In this embodiment, because the rear display screen of the electronic device is relatively small, it can automatically enter the first mode for shooting when the rear display screen enters the shooting interface. That is, it starts a countdown to shoot when the subject is confirmed to be stationary. This automatic entry into the first mode is highly convenient. Furthermore, in this case, the electronic device can automatically shoot, so there is no need to display a shooting button on the rear display screen, avoiding obstruction of the display screen.

[0032] Secondly, an electronic device is also provided, comprising:

[0033] Processor, memory, and one or more programs;

[0034] The one or more programs are stored in the memory, and the one or more programs include instructions that, when executed by the processor, cause the electronic device to perform the method provided in the first aspect above.

[0052] The following explanations of some terms used in the embodiments of this application are provided to facilitate understanding by those skilled in the art.

[0053] The embodiments of this application involve at least one, including one or more; where "multiple" means two or more. Furthermore, it should be understood that in the description of this specification, terms such as "first," "second," and "third" are used only for descriptive purposes and should not be construed as indicating or implying relative importance or order. For example, "first event" and "second event" do not represent the degree of importance of the two or their order, but are merely for descriptive distinction. In the embodiments of this application, "and / or" merely describes an association relationship, indicating that three relationships can exist. For example, A and / or B can represent: A alone, A and B simultaneously, and B alone. Additionally, the character " / " in this document generally indicates that the preceding and following related objects have an "or" relationship.

[0054] The directional terms mentioned in the embodiments of this application, such as "up", "down", "left", "right", "inner", and "outer", are only for reference to the directions in the accompanying drawings. Therefore, the directional terms used are for better and clearer explanation and understanding of the embodiments of this application, and are not intended to indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the embodiments of this application.

[0055] References to "one embodiment," "in some examples," or "some embodiments" as described in the embodiments of this application mean that one or more embodiments of this specification include a specific feature, structure, or characteristic described in connection with that embodiment. Therefore, the phrases "in some examples," "in one embodiment," "in some embodiments," "in other embodiments," "in still other embodiments," etc., appearing in different parts of this specification do not necessarily refer to the same embodiment, but rather mean "one or more, but not all, embodiments," unless otherwise specifically emphasized. The terms "comprising," "including," "having," and variations thereof mean "including but not limited to," unless otherwise specifically emphasized.

[0056] The technical solutions provided in this application can be applied to electronic devices. The electronic device can be any device with image capture capabilities. For example, the electronic device can be a mobile phone, tablet computer, laptop computer, personal computer (PC), ultra-mobile personal computer (UMPC), netbook, personal digital assistant (PDA), or other portable devices; or it can be a wearable device such as a watch or bracelet; or it can be an in-vehicle device, which can be mounted on various means of transportation such as cars, trains, electric vehicles, helicopters, airplanes, ships, bicycles, and motorcycles; or it can be a virtual reality (VR) device, augmented reality (AR) device, mixed reality (MR) device, etc. In short, this application does not limit the specific type of electronic device.

[0057] In the embodiments of this application, the image capturing function of the electronic device may include two types: manual capturing and automatic capturing, which will be described separately below.

[0058] 1. Manual shooting.

[0059] For example, an electronic device takes a picture based on a user's operation. The user operation could be an action performed on a shutter button. For example, such as... Figure 1 This is a schematic diagram of an image capturing interface provided in an embodiment of this application. Figure 1 The image capture interface includes a capture button 100. When the electronic device receives an operation on the capture button 100, it captures an image. This manual shooting method allows the user to take a picture after preparing their shooting posture and triggering the capture button, resulting in images that generally meet the user's expectations. However, in some scenarios, manual shooting is inconvenient and can affect image quality. For example, in a scenario where a user is holding their phone to take a selfie, after adjusting their shooting posture, they need to trigger the capture button on the shooting interface with their hand to take a picture. Understandably, during the process of triggering the capture button, on the one hand, the user needs to look at the capture button, which means they cannot look directly at the camera, resulting in the image where the user's eyes are not looking directly at the lens, affecting aesthetics; on the other hand, triggering the capture button may require adjusting body posture, forcing the user to adjust their original shooting posture, thus affecting the user experience.

[0060] II. Automatic shooting.

[0061] One possible approach is that after the electronic device displays the image capture interface, a timer can be started, and the image is automatically captured when the timer reaches a set duration. Optionally, the timer can be a countdown timer. For example, the set duration could be 2 seconds, 5 seconds, 10 seconds, etc. Figure 2 This is another schematic diagram of an image capturing interface provided in an embodiment of this application. Figure 2 The image capture interface displays a countdown timer; when the countdown reaches 0, the image is automatically captured. This automatic capture method eliminates the need for the user to look at the capture button or adjust their body position to reach it, significantly improving convenience. It should be noted that this automatic capture method can also be called "timed capture," "countdown capture," "delayed capture," or other names without limitation.

[0062] The following embodiments are mainly illustrated using automatic shooting as an example. As mentioned above, in an automatic shooting scenario, the electronic device needs to start a countdown timer, and automatically shoot when the countdown reaches 0. In the embodiments of this application, the electronic device starts the countdown timer in two ways: the first is manual start, and the second is automatic start.

[0063] The first method is to manually start the countdown.

[0064] One possible approach is for the electronic device to start a countdown when it receives a manual operation, and automatically take a picture when the countdown reaches zero. For example, please see... Figure 3 (a) in the figure is a schematic diagram of an image capturing interface provided in an embodiment of this application. Figure 3 In (a), the image capture interface includes a capture button 100. When the electronic device receives an operation on the capture button 100, it starts a countdown, such as... Figure 3 (b) For example, when the electronic device receives an operation on the shutter button 100, it can immediately start a countdown. In this method, after the user triggers the shutter button 100, the countdown starts immediately. The user should ideally prepare their shooting posture before the countdown reaches 0; otherwise, the shooting quality will be affected. Therefore, if the countdown duration is set to be short, the user's preparation time for shooting posture will be very short, which will create a sense of urgency for the user and affect the user experience.

[0065] The second method is to automatically start the countdown.

[0066] One possible approach is for the electronic device to automatically start a countdown when it detects that certain conditions are met, and then automatically take a picture when the countdown reaches zero. For example, please see... Figure 4 (a) in the figure is a schematic diagram of an image capturing interface provided in an embodiment of this application. Figure 4In (a) of the image capture interface, a preview image is included. When the electronic device determines that the preview image meets the conditions, it automatically starts a countdown, such as... Figure 4 (b) In this method, the countdown can start automatically without the user needing to press the shutter button 100, which is quite convenient.

[0067] As mentioned above, the electronic device automatically starts a countdown when it detects that a condition is met. Optionally, the condition may include at least one of the following:

[0068] (1) The preview image contains a human figure, and the human figure is in a static state.

[0069] Optionally, the person in the preview image being stationary can include: the position, posture, expression, or action of the person in the preview image remaining unchanged. It is understood that the preview image may include other objects besides the person, such as the background (e.g., trees, buildings, vehicles). Considering that the background may be stationary or dynamically changing, the electronic device in this embodiment may not need to consider whether the background is stationary. In some embodiments, the person in the preview image being stationary can include: the person in the preview image being stationary relative to the background. For example, the first moving speed of the person is less than the second moving speed of the background; optionally, the difference between the first and second moving speeds is greater than a preset speed. Taking street scene photography as an example, the subject is walking on the street, and vehicles are driving on the street. Therefore, the preview image includes both the person and the vehicles. The moving speed of the person is less than the moving speed of the vehicles, thus determining that the person is stationary relative to the background.

[0070] It is understandable that the preview image may contain one or more figures. Taking a preview image containing N figures as an example, where N is an integer greater than or equal to 2, the electronic device determines that the figures in the preview image are stationary by: determining that M figures in the preview image are stationary, where the ratio of M / N is higher than a threshold, for example, the threshold is 1 / 2, 2 / 3, etc., and / or, the M figures are located at a preset position in the preview image (e.g., the central area). In other words, the countdown can begin when most figures in the preview image are stationary and / or when figures in the central area are stationary.

[0071] In some embodiments, the electronic device may start the countdown immediately when it determines that the person in the preview image is stationary. Alternatively, the electronic device may start the countdown when it determines that the person in the preview image is stationary and the stationary period exceeds a preset duration (indicating that the subject has posed).

[0072] (2) The preview image contains human figures, and the number of human figures remains unchanged.

[0073] In other words, the electronic device automatically starts a countdown to take a picture when it determines that no people are entering or leaving the frame. Optionally, the number of people remains constant, which may include: the number of heads remaining constant, for example, the number of faces remaining constant.

[0074] In some embodiments, the electronic device may start the countdown immediately when it determines that the number of people in the preview image remains constant. Alternatively, the electronic device may start the countdown when it determines that the number of people in the preview image remains constant and the duration of this constant change exceeds a preset duration (indicating that all subjects are in the frame).

[0075] The following text will continue to use the second method (i.e., automatically starting the countdown) as an example for detailed explanation.

[0076] For example, see Figure 5 This is a schematic flowchart of a shooting method provided in an embodiment of this application, as shown below. Figure 5 As shown, the process may include:

[0077] S400 displays the shooting interface. For example, the shooting interface could be... Figure 4 The interface shown in (a) is shown in the image.

[0078] S401, Entering the first mode, which is the automatic countdown mode, also known as the "automatic timer mode". The process of entering the first mode will be explained later. Figure 6 As described in the text.

[0079] S402, Start Algorithm. This algorithm is used to determine whether the conditions are met. If they are met, the countdown begins.

[0080] Optionally, before S402, the function may also include: the electronic device receiving an operation on the shutter button. That is, if the first mode has already been entered, the algorithm is only activated after the user triggers the shutter button to perform a conditional judgment; if the condition is met, a countdown is started.

[0081] S403: The algorithm identifies whether the preview image contains a person. If it does, S404 is executed; otherwise, S403 is executed again.

[0082] Optionally, the algorithm can be an image recognition algorithm that can identify the type of objects contained in the preview image. When an object of the type of person is identified in the preview image, it is determined that the preview image contains a person object.

[0083] S404: The algorithm determines whether the character object is stationary. If it is, then execute S405; otherwise, re-execute S404 or re-execute S403.

[0084] One possible approach is for an electronic device to capture multiple consecutive preview images and determine the location, posture, expression, and movement of a person within each frame. If the position, posture, expression, and movement of the person are identical across multiple consecutive preview images, then the person is determined to be stationary.

[0085] S405, the algorithm determines whether the number of character objects remains unchanged. If so, execute S406; otherwise, re-execute S405, S404, or S403.

[0086] One possible approach is for the electronic device to capture multiple consecutive preview images and determine the number of human objects in each preview image. If the number of human objects is the same in multiple consecutive preview images, then the number of human objects is determined to remain constant.

[0087] S406, countdown begins.

[0088] S407: Take an image when the countdown reaches 0.

[0089] Optionally, the images captured by the electronic device in S407 may include one or more frames; for example, the captured images may be an animated image or an image sequence.

[0090] The above embodiments illustrate two shooting methods: manual and automatic shooting, and the automatic shooting method includes both manual and automatic countdown initiation. In some embodiments, the electronic device may include at least one of a first mode, a second mode, and a third mode. The first mode and the second mode are both automatic shooting modes; for example, the first mode is an automatic countdown initiation mode (also known as an automatic timing mode), and the second mode is a manual countdown initiation mode (also known as a manual timing mode). The third mode is a manual shooting mode. The following describes the image capturing process using an electronic device including the first mode, the second mode, and the third mode as an example.

[0091] For example, see Figure 6 This is a schematic flowchart of an image capturing method provided in an embodiment of this application. Figure 6 As shown, the process includes:

[0092] S500, displaying the shooting interface.

[0093] In this embodiment of the application, when the electronic device displays the shooting interface, it may enter a first mode, a second mode, or a third mode; when entering the third mode, the process of S502 to S503 is used to shoot images; when entering the second mode, the process of S505 to S507 is used to shoot images; when entering the first mode, the process of S510 to S515 is used to shoot images.

[0094] S501, enter the third mode, which is the manual shooting mode.

[0095] In some embodiments, when an electronic device launches a camera application, it defaults to the third mode. In other embodiments, the electronic device is in the third mode even when it has not entered any other shooting mode (e.g., the first or second mode).

[0096] S502: Determine if the shutter button has been pressed. If yes, execute S503; otherwise, re-execute S502.

[0097] S503, taking pictures.

[0098] S504, enter the second mode, which is the manual timer mode, meaning the user needs to manually trigger the countdown.

[0099] One possible approach is that the electronic device enters the second mode after detecting a command indicating that it is in the second mode. For example, the shooting interface includes a second control for indicating the second mode, and the electronic device enters the second mode when it detects that the user clicks on the second control.

[0100] For example, such as Figure 7 In (a), the shooting interface displays a timer control 700. When the electronic device receives an operation on the control 700, it displays the "Manual Timer" option 701 (i.e., the second control). If the electronic device receives an operation on option 701, it enters the second mode.

[0101] For example, such as Figure 7 In (b), the shooting interface displays a timer control 703. When the electronic device receives an operation on the control 703, it displays the "Manual Timer" option 704 (i.e., the second control). If the electronic device receives an operation on the option 704, it enters the second mode.

[0102] For example, such as Figure 7 In (c), the shooting interface displays a timer control 706. When the electronic device receives an operation on the control 706, it displays the "Manual Timer" option 707 (i.e., the second control). If the electronic device receives an operation on the option 707, it enters the second mode.

[0103] For example, such as Figure 8A (a) The shooting interface includes more options 801. After the electronic device detects that the user clicks on more options 801, it displays as follows: Figure 8A (b) The shooting mode interface includes a timer control 802. When the electronic device detects that the user has clicked control 802, it displays the "Manual Timer" option 803 (i.e., the second control). If the electronic device receives an operation on option 803, it enters the second mode.

[0104] For example, such as Figure 8B (a) The shooting interface includes a settings button. After the electronic device detects that the user has clicked the settings button, it displays the following: Figure 8B (b) The settings interface includes a timed shooting option. After the electronic device detects that the user has clicked the timed shooting option, it displays the following: Figure 8B (c) is the interface, which includes two options: "Manual Timer" and "Automatic Timer". When the electronic device receives an operation for the "Manual Timer" option, it displays as shown below. Figure 8B (d) The interface includes a switch button for entering or exiting the second mode.

[0105] S505 checks if the shutter button has been pressed. If so, proceed to S506; otherwise, repeat S505.

[0106] S506, countdown begins.

[0107] In some embodiments, the countdown duration set in S506 can be the default duration in the second mode, such as 5 seconds. This eliminates the need for the user to manually set the countdown duration in the second mode. In other embodiments, the countdown duration set in S506 can be a user-specified duration. One possible approach is as follows: Figure 8B (d) The interface includes options for setting the countdown duration in the second mode, such as 2s, 5s, 10s, etc. Assuming the electronic device determines that the user selects 2s, then the countdown duration in the second mode is set to 2s.

[0108] S507, taking pictures.

[0109] S508, enter the first mode, which is the automatic timer mode, that is, the countdown will start automatically.

[0110] Optionally, entering the first mode can include two methods: automatic entry and manual entry.

[0111] Taking manually entering the first mode as an example, the phone enters the first mode after detecting a command indicating that it is in the first mode. One possible approach is to include a first control on the shooting interface to indicate the first mode; when the electronic device detects that the user clicks on this first control, it enters the first mode.

[0112] For example, such as Figure 7 In (a) of the image capture interface, a timer control 700 is displayed. When the electronic device receives an operation on the control 700, it displays the "Automatic Timer" option 702 (i.e., the first control). If the electronic device receives an operation on option 702, it enters the first mode.

[0113] For example, such as Figure 7 In (b), the shooting interface displays a timing control 703. When the electronic device receives an operation on the control 703, it displays the "automatic timing" option 705 (i.e., the first control). If the electronic device receives an operation on the option 705, it enters the first mode.

[0114] For example, such as Figure 7 In (c), the shooting interface displays a timing control 706. When the electronic device receives an operation on the control 706, it displays the "Automatic Timing" option 708 (i.e., the first control). If the electronic device receives an operation on the option 708, it enters the first mode.

[0115] For example, such as Figure 8A (a) The shooting interface includes more options 801. After the electronic device detects that the user clicks on more options 801, it displays as follows: Figure 8A (b) The shooting mode interface includes a timer control 802. When the electronic device detects that the user has clicked control 802, it displays the "Automatic Timer" option 804 (i.e., the first control). If the electronic device receives an operation on option 804, it enters the first mode.

[0116] For example, such as Figure 8B (a) The shooting interface includes a settings button. After the electronic device detects that the user has clicked the settings button, it displays the following: Figure 8B (b) The settings interface includes a timed shooting option. After the electronic device detects that the user has clicked the timed shooting option, it displays the following: Figure 8B (c) is the interface, which includes two options: "Manual Timer" and "Automatic Timer". When the electronic device receives an operation for the "Automatic Timer" option, it displays as shown below. Figure 8B (e) is an interface that includes a switch button for entering or exiting the first mode.

[0117] Taking automatic entry into the first mode as an example, for instance, the electronic device automatically enters the first mode when it determines that the entry conditions for the first mode are met. Optionally, the entry conditions for the first mode may include at least one of the following:

[0118] (1) The electronic device determines that the current shooting interface is displayed, but the user is not holding the phone. One possible scenario is that the user fixes the electronic device on a tripod and the user is a certain distance away from the electronic device. In this scenario, it can automatically enter the first shooting mode.

[0119] (2) The electronic device includes a first screen and a second screen. The first screen is located on the back of the electronic device, and the second screen is located on the front of the electronic device. The electronic device automatically enters the first mode when it determines that the first screen is currently displaying the shooting interface. That is, it can automatically enter the first mode when the shooting interface is displayed on the rear screen. One possible scenario is, for example, as... Figure 9A The electronic device has a screen (the first screen) on its back, but this screen is relatively small. When the shooting interface is displayed on this screen, it can automatically enter the first mode. Optionally, the shooting interface on this screen may not include the shooting button 100, because displaying the shooting button 100 on a small screen would obscure the entire screen. It should be noted that... Figure 9A Taking the circular rear display screen (i.e., the first screen) as an example, it is understandable that the rear display screen could have other shapes; this is not a limitation. Furthermore, Figure 9A Taking the second screen as an example, it's optional; the second screen may not be a foldable screen. One possible scenario is, for example... Figure 9B When a user uses the rear display screen (i.e., the first screen) to open the shooting interface for a selfie, the camera application detects that the shooting interface is open on the rear display screen and automatically enters the first mode. After entering the first mode, when it detects that the person in the preview image is in a stationary state, it starts a countdown. When the countdown reaches 0, it takes an image.

[0120] Optionally, before the electronic device automatically enters the first mode, it may output a prompt message to remind the user whether to enter the first mode. For example, such as... Figure 10 In (a), the shooting interface displays a prompt: "Enter first mode?". Considering that users may not be familiar with the function of the first mode, in some embodiments, Figure 10 In (a) of the above, when the electronic device receives an operation in response to the prompt information, it displays as shown in the image. Figure 10The interface in (b) includes a brief introduction to the first mode, such as, "Start the countdown while you remain still." Therefore, the user can clearly understand the function of the first mode through this introduction. Optionally, the introduction to the first mode may automatically disappear after a certain duration, or it may disappear upon detecting user interaction (e.g., interaction anywhere within the shooting interface). Continuing... Figure 10 Taking (a) as an example, after the electronic device displays a prompt asking whether to enter the first mode, it enters the first mode if it receives a confirmation command. One possible approach is for the electronic device to prompt the user to tap to confirm entering the first mode; when the electronic device receives a tap, it enters the first mode. Alternatively, the electronic device can display a confirmation control (not shown in the figure), and when it receives an operation on the confirmation control, it enters the first mode. Or, the electronic device can collect an audio signal and detect that the audio signal includes the message "Confirm Entry," then it enters the first mode.

[0121] In some embodiments, after the electronic device enters the first mode, it may display a prompt message to indicate that it has successfully entered the first mode. For example, please see... Figure 11 The electronic device displays a prompt message: "Entering the first mode." Optionally, the prompt message will automatically disappear after a certain period of time.

[0122] S509, startup algorithm.

[0123] S510: The algorithm identifies whether the preview image contains a person. If it does, S511 is executed; otherwise, S510 is executed again.

[0124] S511: The algorithm determines whether the character object is stationary. If it is, S512 is executed; otherwise, S511 or S510 is executed again.

[0125] S512, the algorithm determines whether the number of character objects remains unchanged. If so, execute S513; otherwise, re-execute S512, S511, or S510.

[0126] S513, countdown begins.

[0127] In some embodiments, the countdown duration set in S513 can be the default duration in the first mode, such as 5 seconds. This eliminates the need for the user to manually set the countdown duration in the first mode. In other embodiments, the countdown duration set in S513 can be a user-specified duration. One possible approach is as follows: Figure 8B(e) The interface includes options for setting the countdown duration in the first mode, such as 2s, 5s, 10s, etc. Assuming the electronic device determines that the user selects 2s, then the countdown duration in the first mode is set to 2s.

[0128] S514: Capture an image when the countdown reaches 0.

[0129] Please see Figure 12 This is a schematic diagram illustrating another process of the shooting method provided in one embodiment of this application. This process can be applied to... Figure 9A or Figure 9B The foldable phone shown. Figure 12 The process may include:

[0130] On the S1200, in the camera application, turn on the automatic timer function.

[0131] by Figure 9A Taking a foldable phone as an example, users can launch the camera app on the front display and then turn on the automatic timer function within the camera app. For example, turn on... Figure 8B (e) interface, and trigger the automatic timer switch to turn on.

[0132] The S1201 triggers the automatic timer function when the shooting interface is opened on the external screen.

[0133] It should be noted that the embodiments of this application are not limited to opening the shooting interface on the external screen. One possible way is to first open the shooting interface on the front display screen, and then trigger a switch button to switch the shooting interface to the external screen.

[0134] S1202, determine whether there is a human figure in the preview image. If so, execute S1203; otherwise, continue the detection.

[0135] S1203: Is the character object stationary relative to the background? If yes, proceed to S1204; otherwise, continue the check.

[0136] S1204, countdown begins.

[0137] S1205, countdown ended, automatic photo taking.

[0138] S1206, Next round of shooting. Optionally, S1206 can include continuing to execute S1202 through S1205.

The processor performs image processing, such as identifying whether a person or object exists in the preview image, whether the person or object is stationary, and whether the number of people or objects remains constant. The camera captures images. The display shows the images. The memory stores the images. For example, after the electronic device activates the camera, the display shows a preview image captured by the camera. The processor identifies whether a person or object exists in the preview image, whether the person or object is stationary, and whether the number of people or objects remains constant. When the conditions are met, a countdown begins to take a picture, and then the captured image is stored in the memory.
