External folding screen terminal

An outer folding screen terminal refers to a terminal with a folding angle of 180°, and in the folded state, the entire touch screen is exposed. As shown in FIG. 3 , the terminal 100 is an external folding screen terminal. In the unfolded state, the first supporting surface of the first housing 41 of the terminal 100 is flush with the second supporting surface of the second housing 42 (that is, the included angle is 180°), and the first display area 131, The second display area 132 and the third display area 133 are located on the same plane; when the terminal 100 changes from the unfolded state to the folded state, as shown in FIG. The two backs are close together, and the angle between the first support surface and the second support surface changes from 180° to 0°; in the folded state, as shown in FIG. 4 , the first support surface and the second support surface of the first housing 41 of the terminal 100 The second supporting surfaces of the two housings 42 are parallel (the angle between the first housing 41 and the second housing 42 is 0°), so that the touch screen is in a U-shaped folded state, wherein the third display area of the touch screen 133 forms an exposed U-shaped arc surface.

For example, as shown in FIG. 4 , in the folded state, only the second display area 132 is used to display the user interface, or only the third display area 133 is used to display the user interface.

Inner folding screen terminal

An inner folding screen terminal refers to a terminal with a folding angle of 180°, and in the folded state, the touch screen (all or part) is restrained. As shown in FIG. 5 , the terminal 100 is an inner folding screen terminal. In the unfolded state, the first supporting surface of the first housing 41 of the terminal 100 is flush with the second supporting surface of the second housing 42 (that is, the included angle is 180°), so that the touch screen is in a planar unfolded state (first The display area 131, the second display area 132 and the third display area 133 are located on the same plane); when the terminal 100 changes from the unfolded state to the folded state, as shown in FIG. The second supporting surfaces of the two casings 42 are close together, that is, the angle between the first supporting surface and the second supporting surface changes from 180° to 0°; The second supporting surfaces of the second housing 42 are parallel, so that the touch screen is in a U-shaped folded state, wherein the third display area 133 of the touch screen forms a restrained U-shaped arc. In an optional implementation manner, in the folded state, no user interface is displayed on the entire display area of the touch display screen.

In addition to setting a touch display screen on the supporting surface of the housing, a touch display screen may also be provided on the first back of the first housing 41 and/or the second back of the second housing 42 . When the inner folding screen terminal is in the folded state, the touch screen disposed on the back of the casing is used to display a user interface, which is the same as or different from the user interface displayed on the touch screen in the unfolded state.

In other possible implementations, the folding angle of the terminal 100 can also be 360° (it can be folded inward or outward), and in the folded state, the touch screen of the terminal is exposed or restrained, which is not covered in this embodiment. Be limited.

In the terminal 100 shown in FIGS. 3 to 5 , the first housing 41 and the second housing 42 have the same or similar dimensions, and the folding method of the terminal 100 is called symmetrical folding. In other possible implementation manners, the folding manner of the terminal 100 may also be asymmetric folding. When using asymmetric folding, the size of the first housing 41 and the second housing 42 can be different or the size difference is greater than a threshold (such as 50% or 60% or 70%), correspondingly, the first display area 131 in the touch screen The difference between the area of and the area of the second display region 132 is greater than the threshold.

In the folded state, the area of the first display area 131 is larger than the area of the second display area 132 .

In FIGS. 3 to 6, the terminal 100 includes two shells and a connection assembly for connecting the shells as an example for schematic illustration (the terminal is a two-fold structure). In other possible implementations, the terminal 100 It may include n parts of the housing and n-1 connecting components. Correspondingly, the touch display screen of the terminal 100 includes 2n-1 display areas, and the n-1 display areas corresponding to the connecting components are made of flexible materials, so that A terminal with an n-fold structure is not limited in this embodiment.

At least one other component is also provided in the terminal 100, and the at least one other component includes: a camera, a fingerprint sensor, a proximity light sensor, a distance sensor, and the like. In some embodiments, at least one other component is disposed on the front, side or back of the terminal 100 , such as disposing the fingerprint sensor on the back or side of the housing, and disposing the camera above the touch display 130 .

In other embodiments, at least one other component may be integrated inside or under the touch display screen 130 . In some embodiments, a bone conduction earpiece is placed inside the terminal 100; other components on the front panel of a traditional terminal are integrated into all or part of the area of the touch display 130, for example, the photosensitive element in the camera After splitting into a plurality of photosensitive pixels, each photosensitive pixel is integrated in the black area of each display pixel in the touch display screen 130, so that the touch display screen 130 has an image acquisition function. Since at least one other component is integrated inside or under the touch display screen 130, the terminal 100 has a higher screen-to-body ratio.

In some optional embodiments, a single side of the middle frame of the terminal 100, or two sides (such as the left and right sides), or four sides (such as the upper, lower, left, and right sides) An edge touch sensor is arranged on two sides), and the edge touch sensor is used to detect at least one of the user's touch operation, click operation, press operation and slide operation on the middle frame. The edge touch sensor may be any one of a touch sensor, a thermal sensor, a pressure sensor, and the like.

For example, the terminal 100 also includes components such as a radio frequency circuit, an input unit, a sensor, an audio circuit, a wireless fidelity (Wireless Fidelity, WiFi) module, a power supply, and a Bluetooth module, which will not be repeated here.

Please refer to FIG. 7 , which shows a flow chart of a method for capturing images provided by an exemplary embodiment of the present invention. This method can be applied to the outer folding screen shown in FIG. 3 , FIG. 4 or FIG. 6 In the terminal, it can also be applied in the inner folding screen terminal as shown in Fig. 5 . For ease of understanding, this embodiment is described by taking an application in an inner folding display screen as an example. As shown in Figure 7, the method for taking an image may include:

Step 701, obtain a first parameter, the first parameter includes a folding angle or an angle change value, the folding angle is the angle between the first shell and the second shell, and the angle change value is the angle between the first shell and the second shell Angle change value produced over a period of time.

In the embodiment of the present invention, when the user needs to use the terminal to capture an image, the user can open the image collection application in the terminal. After the image collection application is started, the terminal can acquire the first parameter according to the method. The first parameter may be the folding angle of the terminal, or an angle change value generated by the first housing relative to the second housing.

In a possible implementation manner, the first parameter is the folding angle. The terminal may measure the angle value of the folding angle through an angle sensor. Optionally, the angle sensor may be a piezoelectric sensor, such as a piezoelectric film disposed at the connection between the first housing and the second housing. Since the folding angles between the first casing and the second casing of the terminal are different, the pressure values generated at the knuckles between the first casing and the second casing are different. Therefore, the terminal can determine the size of the folding angle according to the pressure value that the piezoelectric film bears.

In another possible implementation manner, the first parameter may also be an angle change value. The angle change value is used to indicate the angle change value generated within a period of time between the first casing and the second casing. The time period may be a target time period, and the target time period may be a time period of a specified time length set in the terminal, for example, the terminal detects an angle change value within a specified time length of T after the image acquisition application is started. On the one hand, for the accuracy of the detection result, the terminal can set the value of T smaller; on the other hand, in order to save the hardware and software costs of the terminal, the value of T can be set larger. Usually, the value of T can be set in consideration of the accuracy of the detection result and the software and hardware overhead of the terminal. Optionally, the terminal may detect the angle change value periodically, and the terminal may also detect the angle change value aperiodically.

Step 702: Determine a corresponding shooting parameter according to the first parameter, where the shooting parameter is used to indicate an optical parameter of the terminal when shooting an image.

In the embodiment of the present invention, the terminal may pre-save the correspondence between the first parameter and the shooting parameter, and the correspondence may be a linear correspondence or a nonlinear correspondence. When the first parameter is the folding angle, the corresponding relationship may be a one-to-one correspondence, and the folding angle of the specified size corresponds to the specified shooting parameter. In this case, the corresponding relationship can be stored in the terminal in the form of a table.

Optionally, the terminal may store at least one table for each shooting parameter. For example, the shooting parameter may be at least one of focal length, photosensitivity value, exposure compensation, color temperature and contrast, and each shooting parameter has at least one table. Under different conditions, the terminal determines the shooting parameters corresponding to the first parameters according to the table meeting the conditions. Wherein, the user may manually determine the shooting parameters to be adjusted before the terminal executes step 702 . Alternatively, the shooting parameter is a designated one, and the user does not need to manually determine the shooting parameter to be adjusted, and the terminal directly executes step 702 .

Step 703, taking images according to shooting parameters.

In the embodiment of the present invention, after the shooting parameter adjustment is completed, the terminal can shoot an image according to the shooting parameter corresponding to the first parameter under the user's shooting instruction. Or, video is recorded according to the shooting parameters under the user's shooting instruction. Wherein, the recording operation includes recording a short video (small video) with a fixed duration and a custom video segment with a duration defined by the user.

Optionally, after the terminal starts recording after adjusting the shooting parameters. The terminal can still perform step 701 and step 702, so as to realize the terminal's function of adjusting shooting parameters during video recording.

Optionally, when the terminal records a short video with a fixed duration, the terminal can record a short video within a specified time length before the shooting button is triggered, or record a short video within a specified time length after the shooting button is triggered, or record A short video from the specified time length before the capture button is triggered to the specified time length after the capture button is triggered. For example, if the specified recording time length is 4 seconds, the terminal can always cache the short video of the last 4 seconds. When the shooting button is triggered, the terminal saves the short video within 4 seconds before the shooting button is triggered. Alternatively, the terminal can also record a short video within 4 seconds after the shooting button is triggered. or. The terminal can record a short video of 2 seconds before the shooting button is triggered and 2 seconds after it is triggered, a total of 4 seconds.

In summary, the embodiment of the present invention provides a method for shooting images, which utilizes the foldable feature of the folding screen, so that when the terminal is shooting images, the shooting parameters can be adjusted without the user's finger touching the adjustment buttons on the screen. Specifically, the terminal obtains a folding angle between the first casing and the second casing, obtains a corresponding shooting parameter according to the folding angle, and takes an image according to the shooting parameter. Alternatively, the terminal obtains an angle change value generated by the first casing relative to the second casing within a period of time, and obtains corresponding shooting parameters according to the angle change value, and then takes an image. Since the terminal does not need to expand the touch operation interface on the screen to adjust the shooting parameters when the terminal adjusts the shooting parameters, the terminal always displays the viewfinder image on the screen when the user adjusts the shooting parameters, which is beneficial for the user to calibrate the shooting parameters while observing the viewfinder image. The adjustment efficiency of shooting parameters is improved, thereby improving the efficiency of obtaining images with higher imaging quality.

In the embodiment of the present invention, when the first parameter is the folding angle, the terminal obtains the folding angle between the first casing and the second casing as the shooting parameter. In this case, the user can either manually bend the terminal to change the folding angle between the first casing and the second casing to change the shooting parameters, or not change the folding angle so that the terminal is at a position corresponding to the current folding angle. Capture images under shooting parameters.

Please refer to FIG. 8 , which shows a flow chart of a method for capturing images provided by an exemplary embodiment of the present invention. This method can be applied to the outer folding screen as shown in FIG. 3 , FIG. 4 or FIG. 6 In a terminal, it can also be applied in an inner folding screen terminal as shown in FIG. 5 . For ease of understanding, this embodiment is described by taking an application in an inner folding display screen as an example. As shown in Figure 8, the method for taking an image may include:

Step 801, acquire a first angle reading α from an angle sensor.

In the embodiment of the present invention, the terminal can realize the shooting function through a camera application program. The camera application program can be an application program pre-installed in the operating system of the folding screen terminal, or a third-party application program installed by the user through an application market (app store). For example, the camera application program may be a terminal native camera application program, or a third-party application program installed from the application market with extended functions such as a beauty function, a filter function, or an image widget function.

After the camera application program is installed in the terminal, the camera application program can be opened by the user's opening operation. Wherein, the user can click the icon of the camera application on the touch screen to open the camera application, or can open the camera application through voice control.

It should be noted that the opening manner of the above-mentioned camera application program is some of the manners that can be realized in the embodiment of the present invention, and the embodiment of the present invention does not limit the opening manner of the camera application program.

After the folding screen terminal starts the camera application program, the terminal can determine whether to obtain the first angle reading α in the angle sensor according to the user's settings. When the terminal is configured to enable the function of adjusting the shooting parameters through the folding angle, the terminal acquires the first angle reading α through the angle sensor. When the terminal is set to disable the function of shooting parameters adjusted by the folding angle, the folding screen terminal will not acquire the first angle reading α and will not perform step 802 and subsequent steps. For example, the terminal can provide the option of the application scene of the folding angle in the system settings, and the user can enable the application scene of adjusting the shooting parameters through the folding angle, and can also close the application scene of adjusting the shooting parameters through the folding angle.

Optionally, the angle sensor may directly feed back the first angle reading to the processor of the terminal, or may feed back a piece of collected data to the processor. Wherein, when the angle sensor feeds back collected data, the collected data includes but not limited to parameters such as current, voltage, capacitance value or pressure value. The processor determines the first angle reading corresponding to the collected data according to the angle determination relationship. It should be noted that the angle determining relationship may be data preinstalled in a system file of the terminal.

Step 802, detecting whether the first angle reading α is in a preset adjustment interval.

After acquiring the first angle reading α, the terminal may detect whether the first angle reading α is in a preset adjustment interval. Wherein, the preset adjustment interval may be an angle interval preset by a program developer, or an angle interval set by a user according to his own usage habits. Optionally, the user can independently set the angle range of the preset adjustment interval in the settings of the terminal.

In a possible implementation manner of the embodiment of the present invention, the shooting parameter may be a focal length. Optionally, in order to facilitate the user to observe an undistorted image on the display screen of the terminal while adjusting the focus, the folding screen terminal may be as close to the unfolded state as possible when determining the first parameter. For example, the preset adjustment interval can be determined as 180 degrees (that is, the first display area and the second display area are on the same plane) as one end point of the interval, and 170 degrees can be determined as the other end point of the interval, that is, the preset adjustment interval is [170 °, 180°]. In this case, the user can observe the framing images displayed in the first display area and the second display area at the same time when changing the folding angle, which avoids the situation that the framing image observed by the user is deformed and is not conducive to the user's observation of the object to be photographed occur.

Step 803, when the first angle reading α is within the preset adjustment interval, determine the first angle reading α as the first parameter.

Step 804, when the first angle reading is not in the preset adjustment interval, among the left end point angle β and right end point angle γ of the preset adjustment interval, the end point angle with the smaller absolute value of the difference with the first angle reading α determined as the first parameter.

In the embodiment of the present invention, the terminal determines the magnitude of the first parameter according to the relationship between the first angle reading α and the preset adjustment interval. In one scenario, when the first angle reading α is in the preset adjustment interval, the terminal directly determines the first angle reading αe as the first parameter. In another scenario, when the first angle reading α does not belong to the preset adjustment interval, in the left end point angle β and right end point angle γ of the preset adjustment interval, the difference from the first angle reading α will be The interval endpoint angle with smaller absolute value is used as the first parameter. For example, the preset adjustment interval is [170°, 180°], when the first angle reading is 175°, the first parameter is determined to be 175°. When the first angle reading α is 165°, the absolute value of the difference between 165° and 170°, the left end point of the preset adjustment interval, is 5, and the absolute value of the difference between 180° and the right end point of the preset adjustment interval is 15. Therefore, the terminal determines the right end point angle of 170° with a smaller difference as the first parameter.

Step 805: Determine a corresponding shooting parameter according to the first parameter, where the shooting parameter is used to indicate an optical parameter of the terminal when shooting an image.

The execution process of step 805 is the same as the execution process of step 702, please refer to step 702 for details, and will not be repeated here.

Step 806, shoot an image according to the shooting parameters.

In a possible implementation manner in the embodiment of the present invention, the shooting parameter may be at least one of focal length, light sensitivity value, exposure compensation, color temperature, or contrast. When the shooting parameter is a single parameter, the terminal adjusts the single parameter in real time when the user changes the folding angle. When there are two or more shooting parameters, the terminal needs the user to determine which parameter is to be adjusted before the user changes the folding angle. Optionally, the user can either click the parameter icon on the touch screen to determine the shooting parameters to be adjusted, or move the cursor by changing the folding angle in the shooting parameter list selection interface, or press a confirmation button (such as the Physical buttons) to determine the shooting parameters that need to be adjusted. After the shooting parameters are determined, the terminal can shoot images according to the shooting parameters after detecting the user's shooting instruction. Optionally, the terminal may also record video according to the shooting instruction. For the execution method of related terminal shooting, please refer to the content in step 703, which will not be repeated here.

In a manner that can be implemented in the embodiment of the present invention, it is described by taking a terminal that is a terminal with an inner folding display screen as an example. As shown in FIG. 9 , it is a schematic diagram of terminal gestures provided based on the method for capturing images shown in FIG. 8 . In FIG. 9 , an angle 931 smaller than 180° between the first shell 91 and the second shell 92 is called a folding angle. Optionally, in a substantially the same way of expression, the angle 932 can also be used to represent the angle between the casing 91 and the casing 92, wherein, the angle 931 and the angle 932 are a group angle relationship, that is, the angle 931 and The sum of the angles 932 is 360°. When the user uses the terminal 900 to take an image, the framing image is displayed on the foldable display 94 of the terminal 900 , wherein the foldable display 94 is composed of a first display area 941 and a second display area 942 . The preset adjustment interval of the terminal is set to [170°, 180°], and the adjustment parameter is set to focal length. When the user uses the terminal to align the object to be photographed and prepare to shoot, the user can adjust the folding angle by bending the first casing 91 or the second casing 92 . Wherein, the folding angle of 170° may correspond to the maximum focal length (also known as the maximum magnification) of the terminal. As the user changes the folding angle in the preset adjustment interval, the terminal adjusts the focal length of the camera according to the folding angle in real time. When the adjustable angle is less than 170°, the terminal uses the focal length corresponding to 170° as the focal length of the camera, and does not change the focal length. After the user adjusts the focal length, other shooting parameters can also be adjusted. After all the shooting parameters are adjusted, the terminal can shoot images under the user's shooting instruction.

Optionally, in another possible application scenario provided by the embodiment of the present invention, when the folding angle of the terminal does not change any more, the corresponding shooting parameters can be adjusted within a specified range through a preset smart adjustment function. For example, when the shooting parameter is the focal length, the terminal can automatically zoom within the specified range [k-a, k+a] according to the target object selected by the user after the folding angle no longer changes, where k is the focal length corresponding to the current folding angle , a is the preset adjustment radius of the automatic zoom function. The terminal adjusts the current focal length k to the focal length m that makes the image of the target object clearest, and m belongs to the specified range [k-a, k+a].

In summary, the method for capturing images provided by the embodiments of the present invention is applied to a terminal with a foldable display screen, the angle between the first housing and the second housing of the terminal is the folding angle, and the first housing It is connected with the second housing through a connection assembly, and an angle sensor is arranged in the connection assembly. The terminal detects whether the first angle reading α is in the preset adjustment interval by acquiring the first angle reading α in the angle sensor, and when the first angle reading α is in the preset adjustment interval, the terminal determines the first angle reading α as the first angle reading α. One parameter; when the first angle reading α is no longer within the preset adjustment interval, the terminal will preset the left end point angle β and right end point angle γ of the adjustment interval, the absolute value of the difference from the first angle reading α is smaller The endpoint angle of is determined as the first parameter, and then the image is captured according to the shooting parameters. Since the embodiment of the present invention adjusts the shooting parameters of the terminal through the change of the folding angle between the first casing and the second casing, the folding angle of the terminal and the shooting parameters form a corresponding relationship, so that the user does not need to adjust the shooting parameters in the shooting parameter adjustment interface. Switching between the current framing image allows the user to adjust the shooting parameters without touching the touch screen, allowing the user to observe the complete framing image while adjusting the shooting parameters, which improves the efficiency of adjusting shooting parameters and shooting images. .

In addition, in the method provided by the embodiment of the present invention, the terminal determines the first parameter according to the folding angle between the first casing and the second casing, and the first parameter corresponds to a shooting parameter. The user can intuitively feel the adjustment amount of the shooting parameters through the folding angle, making the adjustment of the shooting parameters more intuitive.

Further, in the embodiment of the present invention, the first parameter may also be an angle change value, the angle change value is the angle between the first shell and the second shell, and the angle change value is used to indicate the angle change caused by the folding angle value. Optionally, the angle change value may be an angle change value generated by the folding angle within a target time period. The first housing and the second housing of the terminal are connected through a connection component, and an angle sensor may be placed in the connection component, and the angle sensor is used to measure an angle change value.

Please refer to FIG. 10 , which shows a flow chart of a method for capturing images provided by an exemplary embodiment of the present invention. This method can be applied to the outer folding screen as shown in FIG. 3 , FIG. 4 or FIG. 6 In the terminal, it can also be applied in the inner folding screen terminal as shown in Fig. 5 . For ease of understanding, this embodiment is described by taking an application in an inner folding display screen as an example. As shown in Figure 10, the method for taking an image may include:

Step 1010, acquire the first angle reading of the angle sensor at the initial moment of the target time period.

Step 1020, acquiring a second angle reading of the angle sensor at the end of the target time period.

Step 1030, determine the first parameter according to the angle change value of the second angle reading relative to the first angle reading.

In the embodiment of the present invention, the first housing and the second housing of the terminal are connected through a connecting component, and the terminal may be provided with a sensor in the connecting component. The sensor is used to measure the angle value of the folding angle of the first shell relative to the second shell. Wherein, the sensor may be a piezoelectric film, and when the piezoelectric film is folded at different angles, it will generate different pressure values due to being squeezed by the rigid part in the connection assembly. Therefore, the terminal can acquire the first angle reading of the angle sensor at the start moment of the target time period, and the second angle reading at the end moment of the target time period. Optionally, the target time period may be a unit time preset by the system, the terminal determines a first angle reading and a corresponding second angle reading in a unit time, and determines the first parameter according to the difference between the two. For example, the unit time is 1 second. At the beginning of the 1-second time period, the terminal obtains the first angle reading of 170°; the second angle obtained at the end of the 1-second time period If the reading is 171°, the angle change value is 1°. Optionally, the terminal may use 1° as the first parameter. In order to ensure that the terminal can obtain the angle change value in real time, the terminal may periodically execute steps 1010 to 1030 with a unit time period.

For another implementable manner of the embodiment of the present invention, please refer to FIG. 11 , which is a flow chart of determining a first parameter based on the embodiment shown in FIG. 10 . In FIG. 11 , the terminal may implement step 1030 by executing steps 1031 to 1034, and the specific execution process is as follows.

Step 1031, acquiring the duration of the target time period.

Step 1032, determine the first angular velocity according to the duration of the target time period and the angle change value.

Step 1033: Determine the first adjustment coefficient according to the preset corresponding relationship.

Wherein, the first adjustment coefficient is an adjustment coefficient corresponding to the first angular velocity, and the adjustment coefficient is used to indicate a parameter change amount of a shooting parameter corresponding to a unit angle change value. The terminal determines the first angular velocity by acquiring the duration and angle change value of the target time period, and determines the first adjustment coefficient according to the preset corresponding relationship.

Optionally, in a possible implementation of this step, the angular velocity of the bending of the first casing relative to the second casing will affect the value of the first parameter. When the angular velocity of the bending is fast, the first The variation range of the parameter is larger; when the angular velocity of the folding is slower, the variation range of the first parameter is smaller. Specifically, the terminal may acquire N angular velocity intervals, and the N angular velocity intervals are connected end to end. Moreover, when the angular change value of the first casing relative to the second casing is fixed, the greater the angular velocity, the greater the variation of the first parameter. The terminal may determine the angular velocity interval to which the first angular velocity belongs from the N angular velocity intervals, and determine the adjustment coefficient corresponding to the angular velocity interval to which the first angular velocity belongs as the first adjustment coefficient, where the angular velocity interval and the adjustment coefficient are positively correlated.

Optionally, for the first angular velocity interval and the second angular velocity interval in the N angular velocity intervals, if any angular velocity belonging to the first angular velocity interval is greater than any angular velocity belonging to the second angular velocity interval, then the adjustment corresponding to the first angular velocity interval The coefficient is greater than the adjustment coefficient corresponding to the second angular velocity interval.

Optionally, the meaning that the N angular velocity intervals are connected end to end means that the N angular velocity intervals are sequentially connected end to end to form a large interval. And for any angular velocity belonging to the large interval, there is one and only one angular velocity interval corresponding to it.

For example, when the user bends the folding screen of the terminal at a faster angular speed, it means that the user may think that the current shooting parameters are far from the shooting parameters he wants to obtain. Therefore, at this time, the terminal provides the first angle with a larger value according to the first angular velocity with a larger value, so that the terminal can provide a larger first parameter in the case of a specified angle change value, and then the terminal can generate a larger value. Shooting parameter adjustment amount. On the contrary, when the first angular velocity is slow, it means that the user may think that the difference between the current shooting parameters and the shooting parameters he wants is small, and needs to slow down the speed of bending the folding screen. Therefore, the terminal will provide a smaller The adjustment coefficient allows the user to obtain a smaller change in shooting parameters under the same angle change value. Exemplarily, taking Table 1 as an example, a preset corresponding relationship between an angular velocity and an adjustment coefficient is introduced.

Table I

Angular velocity (rad/s) [0,0.02) [0.02,0.04) [0.04,+∞) Adjustment coefficient 0.5 1 1.5

According to the preset corresponding relationship provided in Table 1, when the angular velocity generated by the terminal’s folding screen within the target time period belongs to the interval [0,0.02), the adjustment coefficient is 0.5, which means that when the first housing and the second When the change value of the angle between the housings is 1°, the terminal determines the first parameter as 0.5° according to the adjustment coefficient of 0.5. It can be seen that under the same angle change value, the faster the user bends the folding screen, the larger the value of the first parameter is obtained.

Step 1034, determine the first parameter according to the angle change value and the first adjustment coefficient.

In the method provided in the embodiment of the present invention, the terminal may determine the first parameter by using the angle change value to determine the first adjustment coefficient. For example, when the first adjustment coefficient is 0.5 and the angle change value is 3°, the first parameter is 1.5°. When the first adjustment coefficient is 1.5 and the angle change value is 3°, the first parameter is 4.5°. Intuitively speaking, the faster the folding screen of the terminal is bent, the greater the value of the first parameter corresponding to the same angle change value.

Optionally, in another possible implementation of this step, the terminal may continuously acquire the first angle change value and the second angle change value, where the first angle change value and the second angle change value are two values continuously acquired by the terminal. Angle change values, that is, the terminal obtains two angle change values for two consecutive periods of time. When the signs of the positive and negative numbers of the first angle change value and the second angle change value are different, the terminal determines the first parameter according to the second angle change value and the second adjustment coefficient, and the second adjustment coefficient is not greater than the value corresponding to the second angle change value. first adjustment factor.

For example, when the user adjusts the shooting parameters by bending the folding screen of the terminal, the user may bend the folding angle beyond the desired folding angle position. At this time, in order to obtain better shooting effects, the user will bend the folding screen in the opposite direction. If the first angle change value of the user's bending is +0.5°, and the second angle change value of the subsequent bending is -0.7°, it means that the user may bend the folding screen beyond the desired folding angle position. At this time, in order to enable the user to accurately adjust the shooting parameters, the terminal may determine the first parameter according to the second adjustment coefficient and the angle change value. Wherein, the second adjustment coefficient is not greater than the first adjustment coefficient corresponding to the second angle change value. It should be noted that the second angular change value corresponds to an angular velocity within its own target time period, and the angular velocity corresponds to an angular velocity interval, and the adjustment coefficient corresponding to the angular velocity interval is the first adjustment coefficient corresponding to the second angular change value. For example, the first adjustment coefficient corresponding to the second angle change value is 1, and the second adjustment coefficient may be 1 or a positive number smaller than 1.

Step 1040: Determine corresponding shooting parameters according to the first parameter, where the shooting parameters are used to indicate the optical parameters of the terminal when shooting images.

In the embodiment of the present invention, the execution process of step 1040 is the same as the execution process of step 702, please refer to step 702 for details, and will not be repeated here.

Step 1050, shoot an image according to the shooting parameters.

In the embodiment of the present invention, the execution process of step 1050 is the same as the execution process of step 703, please refer to step 703 for details, and will not be repeated here.

To sum up, the method for capturing images provided by the embodiment of the present invention is a parameter determined by acquiring the first angle reading of the angle sensor at the start moment of the target time period and the second angle reading at the end moment of the target time period, A corresponding shooting parameter is determined according to the first parameter, and the object is shot according to the shooting parameter. Since the shooting parameter is an optical parameter used to indicate that the terminal is shooting an image, and the terminal can adjust the shooting parameter according to the angle change value. Therefore, the terminal can start to adjust the shooting parameters when the current folding angle is any angle, which makes the adjustment of the shooting parameters more convenient, improves the adjustment efficiency of the shooting parameters, and further improves the efficiency of shooting images.

In addition, the first angular velocity is determined by acquiring the duration and angle change value of the target time period, the first adjustment coefficient corresponding to the first angular speed is determined according to the preset correspondence relationship, and the first parameter is determined according to the angle change value and the first adjustment coefficient, The speed of the change of the angle change value is realized to produce the first parameter with different sizes. When the user adjusts the folding angle at a faster angular speed, the shooting parameters can be adjusted with coarse precision, and when the folding angle is adjusted at a slower angular speed, the shooting parameters can be adjusted with fine precision, while ensuring the adjustment efficiency of higher shooting parameters , improving the accuracy of adjusting the shooting parameters.

In addition, when the positive and negative signs of the continuously acquired first angle change value and the second angle change value are different through the terminal, the terminal will determine the first parameter according to the second adjustment coefficient and the second angle change value, wherein the second adjustment coefficient The first adjustment coefficient not greater than the second angle change value can enable the terminal to adjust toward the target value in a fine-precision manner after the adjustment of the shooting parameter exceeds the target value, which improves the efficiency of adjusting the shooting parameter.
