In the scene of walking, running and the like, when a user holds a mobile phone to shoot a video, there is often a problem that the video image shot is unstable and has poor definition due to mobile phone shaking.

[0004] Currently, optical image stabilization (OIS) can be used to perform anti-shaking processing on the mobile phone. The OIS refers to moving a lens to a target position by using a motor, so as to offset the lens displacement caused by mobile phone shaking. However, for a scene with large lens displacement, the actual position to which the lens moves may exceed the target position, the anti-shaking effect is poor, and the definition of the video image cannot be guaranteed.

[0029] Illustrative embodiments of the present application include, but are not limited to, a photographing method, a chip and an electronic device.

[0030] It can be understood that the technical solutions of the present application are applicable to electronic devices with lenses, for example, including but not limited to mobile phones, smart watches, televisions, tablet computers, wearable devices, vehicle-mounted devices, augmented reality (AR) / virtual reality (VR) devices, notebook computers, ultra-mobile personal computers (UMPCs), netbooks, personal digital assistants (PDAs), etc., and the specific type of electronic device is not limited by the embodiments of the present application.

[0031] It can be understood that in the process of a user using an electronic device such as a mobile phone to shoot a video while running, the user's arm will vibrate with the running, causing the lens of the mobile phone to vibrate with the vibration of the user's arm, and in some cases, the shooting object in the video frame can be out of frame.

[0032] In some embodiments, the amount of vibration of the lens of the mobile phone, such as the vibration distance and the vibration angle, can be obtained by a position sensor, a gyroscope or an accelerometer, and then the motor is driven based on the vibration amount to push the lens to move in the opposite direction, thereby compensating for the vibration amount of the lens.

[0033] FIG. 1 shows a schematic diagram of the compensated vibration distance varying with time obtained by compensating for the vibration distance caused by camera vibration by a closed-loop driving control chip, wherein the horizontal axis is time and the vertical axis is vibration distance. As shown in FIG. 1, the vibration distance caused by camera vibration is continuously compensated by the closed-loop driving control chip, so that the vibration distance caused by camera vibration constantly tends to 0. As can be seen from the schematic diagram shown in FIG. 1, the motion trajectory of the lens driven by the closed-loop driving control chip is not only related to the vibration amount of the camera, but in some scenarios, after compensating for the vibration amount, the lens needs to be driven to a specific position and maintained for a certain period of time, and then the lens is driven to move according to the camera vibration amount.

[0034] It can be understood that by driving the lens to a specific position and maintaining it for a certain period of time, the lens can be more stable when moving and turning, reducing misalignment and abruptness, and making the lens movement more natural and smooth.

[0035] It can be understood that, in the application process of OIS optical image stabilization, for a large-span step signal, for example, the amplitude s2 between the tth frame and the t+1th frame in the driving signal is greater than the target threshold, for example, as shown in FIG. 2, for a case where the amplitude s2 between the tth frame and the t+1th frame needs to be compensated, the closed-loop driving control chip will have an overshoot in the response process. As shown in the actual response signal in FIG. 2, the peak value of the actual response signal will exceed the excitation signal with the mapped amplitude s2, resulting in that, in the process of compensating the jitter amount, the actual distance of the lens movement (the distance corresponding to the actual response signal) will exceed the theoretical moving distance corresponding to the excitation signal, that is, the actual position of the lens will exceed the target position, and the time for the lens to stabilize to the target position under the closed-loop control is long, so that the captured image is still not clear.

[0036] To avoid the case where the actual position of the lens movement exceeds the target position, an embodiment of the present application provides a photographing method, which comprises: obtaining a driving signal, and determining a first target position and a second target position of a motor of an electronic device based on the driving signal; dividing the driving signal into a plurality of continuous sub-driving signals, and controlling the motor to move from the first target position to the second target position based on the plurality of continuous sub-driving signals. The amplitude of the sub-driving signal obtained by the division is less than or equal to a target threshold.

[0037] For example, as shown in FIG. 3, the excitation signal (corresponding to the driving signal) mapping the tth frame first target position and the t+1th frame second target position can be divided into a plurality of small step signals (corresponding to a plurality of sub-driving signals) in a continuous multi-stage ladder shape as shown in the reshaped excitation signal.

[0038] It can be understood that, in the application process of OIS optical image stabilization, for a small-span step signal, for example, the amplitude s2 between the tth frame and the t+1th frame in the driving signal is less than or equal to the target threshold, the closed-loop controller will not have an overshoot in the response process, therefore, the actual response signal driving the lens movement is consistent with the trajectory of the excitation signal with the mapped amplitude s2, and the actual position of the lens will not exceed the target position.

[0039] In an embodiment of the present application, the driving signal can be divided according to a division condition; wherein the division condition comprises the number of sub-driving signals and / or the holding time of each sub-driving signal.

[0040] For example, the amplitude of the driving signal is s2, the holding time of the motor of the electronic device at the second target position is t1 based on the driving signal, and the number of sub-driving signals is n1, then the amplitude of each sub-driving signal is (s2 / n1), and the holding time of the signal after the step of each sub-driving signal is (t1 / n1). Wherein n1 is a positive integer greater than or equal to 2.

[0041] For example, the amplitude of the driving signal is s2, the holding time of the motor of the electronic device at the second target position is t1 based on the driving signal, the holding time of each sub-driving signal is t2, and the number of sub-driving signals is (t1 / t2). The amplitude of each sub-driving signal is (s2×t2 / t1).

[0042] For example, the amplitude of the driving signal is s2, the holding time of the motor of the electronic device at the second target position is t1 based on the driving signal, the number of sub-driving signals is n1, the holding time of each sub-driving signal is t2, and (n1×t2)≤t1. The amplitude of each sub-driving signal is (s2 / n1).

[0043] In the embodiments of the present application, the amplitude of each sub-driving signal is less than or equal to the target threshold.

[0044] It can be understood that (n1×t2)≤t1 can avoid the time of stabilizing the lens to the second target position (the sum of the holding times of the sub-driving signals is n1×t2) exceeding the holding time of the second target position, avoid the lens not being stabilized to the second target position when the next input signal is obtained, and prolong the time of stabilizing the lens to the second target position.

[0045] It can be understood that the number n1 of sub-driving signals obtained by division and the holding time t2 of each sub-driving signal can be set according to actual conditions.

[0046] It can be understood that by driving the lens to a specific position and maintaining for a certain time (corresponding to the holding time of the lens at the second target position), the lens can be more stable when moving and turning, the misalignment and the sense of abruptness can be reduced, and the lens movement can be more natural and smooth.

[0047] In this way, by dividing the large step signal into a plurality of small step signals in the form of continuous multi-stage steps, the overshoot of the closed-loop controller when responding to the step signal is avoided, and the time of stabilizing the lens to the target position can be set according to actual application scenarios, so that the lens can be quickly stabilized at the target position.

[0048] The structure of the photographing device provided in the embodiments of the present application will be introduced below. As shown in FIG. 4, the photographing device includes a stage waveform shaping, a closed-loop feedback system (or a closed-loop feedback system), a motor, and a lens. The output end of the stage waveform shaping is connected to the input end of the closed-loop feedback system.

[0049] In the embodiments of the present application, the phased waveform shaping is used to determine whether the amplitude s2 between the tth frame and the (t+1)th frame is greater than a target threshold, if the determination result is yes, the large step signal between the tth frame and the (t+1)th frame is split into multiple small step signals (multiple sub-driving signals) in multiple steps; if the determination result is no, the large step signal between the tth frame and the (t+1)th frame is sent to the closed-loop feedback system.

[0050] For example, after the large step signal between the tth frame and the (t+1)th frame as shown in FIG. 5(a) is input to the phased waveform shaping, when it is determined that the amplitude s2 of the large step signal between the tth frame and the (t+1)th frame is greater than the target threshold, the large step signal between the tth frame and the (t+1)th frame is split into multiple small step signals as shown in FIG. 5(b).

[0051] It can be understood that the number of steps (as shown in FIG. 6) in which the large step signal is split by the phased waveform shaping, i.e., the number of small step signals and the holding time of each step (as shown in FIG. 6), can be set according to actual conditions.

[0052] For example, the amplitude of the large step signal is s2, the holding time of the motor of the electronic device at the second target position determined based on the large step signal is t1, and the number of small step signals is n1, then the amplitude of each small step signal is (s2 / n1), and the holding time of the signal after each small step signal is (t1 / n1). Wherein, n1 is a positive integer greater than or equal to 2.

[0053] For example, the amplitude of the large step signal is s2, the holding time of the motor of the electronic device at the second target position determined based on the large step signal is t1, and the holding time of each small step signal is t2, then the number of small step signals is (t1 / t2), and the amplitude of each small step signal is (s2×t2 / t1).

[0054] For example, the amplitude of the large step signal is s2, the holding time of the motor of the electronic device at the second target position determined based on the large step signal is t1, the number of small step signals is n1, and the holding time of each small step signal is t2, and (n1×t2)≤t1, then the amplitude of each small step signal is (s2 / n1).

[0055] In the embodiments of the present application, the amplitude of each small step signal is less than or equal to the target threshold.

[0056] It can be understood that the closed-loop controller in the closed-loop control system has a small overshoot when responding to a small amplitude step signal, and by adjusting the number of split stages and the step time, a large step signal is divided into a plurality of small step signals in the form of continuous multiple steps, thereby avoiding overshoot of the closed-loop controller when responding to a step signal. The working principle of the closed-loop control system is described below and will not be repeated here.

[0057] In order to make the purpose, technical solutions and advantages of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and exhaustively below with the video recording scene as an example and in conjunction with the drawings.

[0058] FIG. 7 shows a schematic diagram of a shooting method according to an embodiment of the present application. It can be understood that the execution subjects of the schematic diagram shown in FIG. 7 are all electronic devices 100. In order to simplify the description, the execution subjects of each step will not be repeated when introducing the schematic diagram shown in FIG. 7. As shown in FIG. 7, the shooting method includes:

[0059] 101: Obtain a driving signal, and determine a first target position and a second target position of a motor of the electronic device based on the driving signal.

[0060] In the embodiments of the present application, the stage waveform shaping can obtain the driving signal of the motor during the user uses the electronic device 100 to shoot, wherein the driving signal is a signal representing the target position of the motor of the electronic device changing with time. The first target position of the motor of the electronic device at the tth frame can be determined according to the signal before the step in the driving signal, and the second target position of the motor of the electronic device at the t+1th frame can be determined according to the signal after the step in the driving signal. Wherein, the waveform diagram of the first target position at the tth frame and the second target position at the t+1th frame is shown in the excitation signal in FIG. 3.

[0061] In some embodiments, the stage waveform shaping can obtain the driving signal in the case of determining that the electronic device 100 is in a shaking scene; wherein the shaking scene includes any one of a running scene, a walking scene, and a performance scene.

[0062] It can be understood that the electronic device 100 can obtain the shaking data through the position sensor in the closed-loop feedback system, and determine the scene in which the electronic device 100 is currently located according to the shaking data. For example, if it is determined that the shaking amplitude of the shaking signal corresponding to the shaking data is greater than a first amplitude, and the variance of the shaking signal is greater than a first variance, it is determined that the electronic device 100 is in a shaking scene.

[0063] 102: Divide the driving signal into a plurality of continuous sub-driving signals.

[0064] In the embodiment of the present application, the phased waveform shaping can first determine whether the amplitude s2 of the driving signal is greater than a target threshold (a preset distance). If the amplitude s2 of the driving signal is less than or equal to the target threshold, the phased waveform shaping does not process the driving signal, and directly outputs the driving signal to the closed-loop feedback system, so as to drive the motor to drive the lens to move according to the driving signal through the closed-loop feedback system. If the amplitude s2 of the driving signal is greater than the target threshold, the phased waveform shaping divides the driving signal into a plurality of continuous sub-driving signals, and then sends the plurality of continuous sub-driving signals to the closed-loop feedback system, so as to drive the motor to drive the lens to move according to the plurality of sub-driving signals through the closed-loop feedback system in stages.

[0065] In the embodiment of the present application, the driving signal can be divided into a plurality of continuous sub-driving signals according to the division condition, wherein the division condition includes at least one of the number of sub-driving signals and the holding time of the sub-driving signal.

[0066] In the embodiment of the present application, the driving signal can be divided according to the division condition; wherein the division condition includes the number of sub-driving signals and / or the holding time of each sub-driving signal.

[0067] For example, the amplitude of the driving signal is s2, the holding time of the motor of the electronic device at the second target position is t1 based on the driving signal, and the number of sub-driving signals is n1, then the amplitude of each sub-driving signal is (s2 / n1), and the holding time of the signal after each sub-driving signal is stepped is (t1 / n1). Wherein n1 is a positive integer greater than or equal to 2.

[0068] For example, the amplitude of the driving signal is s2, the holding time of the motor of the electronic device at the second target position is t1 based on the driving signal, and the holding time of each sub-driving signal is t2, then the number of sub-driving signals is (t1 / t2), and the amplitude of each sub-driving signal is (s2×t2 / t1).

[0069] For example, the amplitude of the driving signal is s2, the holding time of the motor of the electronic device at the second target position is t1 based on the driving signal, the number of sub-driving signals is n1, and the holding time of each sub-driving signal is t2, and (n1×t2)≤t1, then the amplitude of each sub-driving signal is (s2 / n1).

[0070] In the embodiment of the present application, the amplitude of each sub-driving signal in the plurality of continuous sub-driving signals is less than or equal to the target threshold.

[0071] It can be understood that the driving time corresponding to the plurality of sub-driving signals is less than or equal to the driving time corresponding to the driving signal, that is, the sum of the holding times of the plurality of continuous sub-driving signals is less than or equal to the holding time of the motor at the second target position.

[0072] It can be understood that the closed-loop controller in the closed-loop control system has a small overshoot when responding to a small-amplitude step signal (e.g., an amplitude less than or equal to a target threshold value), and by adjusting the number of split stages and the step time, a large step signal is divided into a plurality of small step signals in the form of continuous multiple steps, thereby avoiding overshoot of the closed-loop controller when responding to a step signal.

[0073] 103: controlling the motor to move from the first target position to the second target position based on the plurality of continuous sub-driving signals.

[0074] In the embodiments of the present application, the plurality of continuous sub-driving signals can be obtained through a closed-loop feedback system, and the motor is controlled to move based on the plurality of continuous sub-driving signals. As shown in FIG. 4, the closed-loop feedback system includes a subtracter, a closed-loop controller, a current / voltage driver, and a position sensor.

[0075] The position sensor is configured to obtain a current position of the motor and generate a position signal of the current position of the motor, and feed back the position signal of the current position of the motor to the subtracter.

[0076] The subtracter is configured to obtain a signal after a step in a driving signal of the motor (or a preset target position signal) and receive the position signal of the current position of the motor fed back from the position sensor, and calculate a difference between the signal after the step in the driving signal of the motor and the position signal of the current position of the motor to obtain an amplitude s1 of an actual driving signal. The driving signal is configured to drive the motor to compensate for an amount of shaking of the lens, and the driving signal is a signal representing a target position of the motor of the electronic device changing with time.

[0077] In some embodiments, the signal after the step in the driving signal of the motor can be generated by an upper computer, a microcontroller, or a motion controller in a control system and input to the subtracter; in other embodiments, the signal after the step in the driving signal of the motor can also be sent to the subtracter by an external device, such as a programmable logic controller or a computer through a communication interface.

[0078] The closed-loop controller is configured to generate a control signal according to the amplitude s1 of the actual driving signal.

[0079] The current / voltage driver is configured to drive the motor based on the control signal to push the lens to move, thereby compensating for an amount of shaking due to shaking of the camera.

[0080] For example, in the process of controlling the motor to move from the first target position to the second target position based on the continuous multiple sub-driving signals, when the control of any one of the continuous multiple sub-driving signals is completed, the position sensor acquires the position signal of the current position of the motor, and determines the first amplitude according to the position signal of the current position of the motor and the signal after the current sub-driving signal step.

[0081] In some embodiments, controlling the motor to move based on the updated position signal of the motor (the first control signal) and the next sub-driving signal comprises: updating the updated position signal of the motor to the position signal before the step of the next sub-driving signal; and controlling the motor to generate movement based on the updated next sub-driving signal.

[0082] In the embodiments of the present application, the position signal of the current position of the motor can be acquired periodically in the process of controlling the motor to move based on the sub-driving signal.

[0083] In the embodiments of the present application, controlling the motor to generate movement based on the updated position signal of the motor (i.e. the actual position of the motor) and the next sub-driving signal can improve the accuracy in the process of moving the motor.

[0084] In this way, by dividing the large step signal into continuous multiple sub-driving signals in a stepped manner, the overshoot generated when the closed-loop controller responds to the step signal is reduced, the time for the lens to move to the target position is shortened, and the lens is quickly stabilized at the target position.
