The embodiment of the disclosure provides an information processing method, a camera module and electronic equipment. The information processing method may include: a target acquisition process, a movement control process and an image acquisition process. In the target acquisition process, a target position is obtained. And then, carrying out a movement control process to control the lens in the camera module to move from the initial position to the target position. In the process of moving the lens from the initial position to the target position, an image acquisition process is performed to obtain at least one first acquired image for at least one acquisition position. Wherein the at least one first captured image acquired during the image capturing process may be part or all of the frame images in the continuous output file.
Fig. 1 schematically shows an application scenario of an information processing method, a camera module, and an electronic device according to an embodiment of the present disclosure. It should be noted that fig. 1 is only an example of a scenario in which the embodiments of the present disclosure may be applied to help those skilled in the art understand the technical content of the present disclosure, but does not mean that the embodiments of the present disclosure may not be applied to other devices, systems, environments or scenarios.
As shown in fig. 1, the application scenario 100 illustrates a scenario in which a user takes an image (e.g., including pictures and videos) using an electronic device 101. When the user triggers a physical key or a virtual key on the electronic device 100 to start video photographing, the electronic device 100 starts video photographing. During video capture, a user may preview via a display screen of the electronic device 100. And then multimedia files such as dynamic pictures, videos and the like can be obtained by using the shot images.
The electronic device 101 shown in fig. 1 is a smartphone, and may have one camera or a plurality of cameras. In other embodiments, the electronic device 101 may be various electronic devices having a camera module and supporting video/image capturing, including but not limited to a smart phone, a tablet computer, a laptop portable computer, a desktop computer, and the like, without limitation.
In some cases, in order to enhance the interest or the expression effect of the multimedia file, the user may want to obtain some special effects in the multimedia file, such as a jitter (jitter) effect of the frames in the multimedia file.
In one processing mode, the dithering effect in the multimedia file is obtained by performing post-editing processing on an image by using a digital image processing technology on the basis of the image which is obtained by shooting by a camera module of the electronic equipment. For example, a shot picture is rotated and cut at different angles to obtain a plurality of processed pictures, and the plurality of processed pictures are combined into a dynamic picture with a shaking effect. However, since the plurality of processed pictures all correspond to the same field of view (angle of view) and the same imaging range (angle of coverage) of the camera assembly of the electronic device, that is, the plurality of processed pictures are derived from the same capture scene with respect to the electronic device, the processed dithering effect is not natural, significant and real enough.
According to an embodiment of the present disclosure, there is provided an information processing method for obtaining a multimedia file having a more realistic, natural, and significant dithering effect by controlling mechanical movement and image capturing of a lens in a camera module of an electronic device. The method is illustrated by the figure below. It should be noted that the sequence numbers of the respective operations in the following methods are merely used as representations of the operations for description, and should not be construed as representing the execution order of the respective operations. The method need not be performed in the exact order shown, unless explicitly stated.
Fig. 2 schematically shows a flow chart of an information processing method according to an embodiment of the present disclosure. The method is applied to the electronic equipment, and the electronic equipment at least comprises a camera module (lens), and the camera module at least comprises a lens (lens).
As shown in fig. 2, the method may include operations S210 to S230 as follows.
In operation S210, a target position is obtained.
The target position represents a deviation position of a lens in a camera module of the desired electronic device relative to the camera module, and may be represented by coordinates relative to a body coordinate system of the electronic device, or may be represented by coordinates relative to a world coordinate system, which is not limited herein. The target positions can include one or more, and any acquired target position needs to be subjected to subsequent operation.
Then, in operation S220, the lens in the camera module is controlled to move from the initial position to the target position.
The lens of the camera module is a lens group consisting of one or more lenses.
Exemplarily, fig. 3 schematically shows an example schematic diagram of a lens shift according to an embodiment of the present disclosure. As shown in fig. 3(a), when the lens 301 is in the initial position, an optical axis (optical axis) (shown by a dotted line) of the lens 301 passes through the center of the photosensitive element 302 in the camera module 300, i.e., the optical center of the lens 301 is collinear with the center of the photosensitive element 302. As shown in fig. 3(b), when the lens 301 is moved from the initial position to the target position, the optical axis of the lens 301 is shifted from the center of the photosensitive element 302, i.e., the optical center of the lens 301 and the center of the photosensitive element 302 are no longer collinear. In other embodiments, the initial position may also be set as required, and it should be noted that the effective photosensitive range of the photosensitive element can always cover the imaging range of the lens in the process of moving the lens from the initial position to the target position.
Then, in operation S230, at least one first captured image for at least one capture position is obtained as a frame image in a continuous output file in the course of moving the lens from the initial position to the target position.
Wherein, at least one acquisition position can be preset according to actual needs. For example, the target position is taken as one capturing position, and the lens is controlled to capture one first captured image while the lens is moved to the target position. When the number of the first captured images is plural, the first captured images may be used as one frame image of the subsequent continuous output file, and when the number of the first captured images is plural, the first captured images may be used as part or all of the frame images of the subsequent continuous output file. The continuous output file is the multimedia file described above, and may be, for example, a moving picture, a video, or the like.
As can be understood by those skilled in the art, the information processing method according to the embodiment of the present disclosure controls the lens in the camera module to move from the initial position to the target position after obtaining the target position, and controls the lens to capture at least one first captured image during the movement process, so as to serve as a part of or all of frame images in the multimedia file to be output. Different frame images in the multimedia file are acquired by the lens at different acquisition positions and correspond to different acquisition scenes, so that a shaking effect can be formed based on the frame images from the different acquisition scenes in the multimedia file, and the multimedia file is more real, remarkable and natural.
Further, to facilitate controlling the lens to move to a new target position next time, the information processing method according to the embodiment of the present disclosure may further include: and after detecting that the lens moves from the initial position to the target position, controlling the lens to return to the initial position from the target position. Following the example shown in fig. 3 above, after the control lens is moved from the position shown in fig. 3(a) to the position shown in fig. 3(b), the control lens is then returned from the position shown in fig. 3(b) to the position shown in fig. 3 (a).
For the case where only one target position is acquired, according to an embodiment of the present disclosure, at least one first captured image is captured in the process of controlling the lens to move from the initial position to the target position, and the at least one first captured image is used for presenting different captured scenes of the lens in the moving process. Further, when the lens is located at the initial position, the lens can be controlled to capture a second captured image, and the second captured image is used for presenting a captured scene corresponding to the lens at the initial position (i.e. when the lens is not in a moving state). Then, a continuous output file is generated based on the at least one first captured image and the second captured image. For example, the at least one first captured image and the second captured image may be combined into a continuous output file in the order from the front to the back of the image capturing time, and since the at least one first captured image and the second captured image respectively represent different capturing scenes, the continuous output file represents a transition between the different capturing scenes, that is, a shaking effect with a real and strong appearance is formed.
For the case where multiple target positions are acquired, the multiple target positions constitute a target position sequence { p1，p2，...，pNWhere N is an integer greater than 1. According to an embodiment of the present disclosure, for the sequence of target positions { p }1，p2，...，pNAny target position p iniControlling the lens to move from the initial position to the any one target position piThen controlling the lens to move from any one of the target positions piAnd returning to the initial position, wherein i is an integer which is more than or equal to 1 and less than or equal to N. And moving the lens from the initial position to the any one of the target positions piIn the process, the lens is controlled to collect M first collected images { pi，jJ is an integer of 1 or more and M or less. Then, the lens is controlled to move from any target position piAfter the lens returns to the initial position, the lens is controlled to move from the initial position to any target position p after a preset time intervaliAt the rear target position pi+1. Similarly, the lens is controlled to move from the initial position to the target position pi+1In the process, the lens is controlled to collect M first collected images { p(i+1)，jAnd then controlling the lens to move from the target position pi+1And moving to the initial position. And repeating the steps until all the target positions in the target position sequence are processed, and obtaining at least one first acquisition image aiming at each target position.
It is to be understood that, after obtaining the plurality of target positions, for any one of the plurality of target positions, after the lens is restored from a previous target position of the any one target position to the initial position, the above-described embodiment controls the lens to move from the initial position to the any one target position after a preset time interval, that is, controls the frequency of multiple movements of the lens for the plurality of target positions by the preset time interval. The first captured image { p obtained as described above1，j，p2，j，...，pN，jAnd the camera is used for presenting different acquisition scenes of the lens in multiple moving processes. Further, when the lens is located at the initial position, the lens can be controlled to capture a second captured image, and the second captured image is used for presenting a captured scene corresponding to the lens at the initial position (i.e. when the lens is not in a moving state). Then, based on the first captured image { p obtained as described above1，j，p2，j，...，pN，jAnd (6) generating a continuous output file together with the second collected image. For example, the at least one first captured image and the second captured image may be combined into a continuous output file in the order from the front to the back of the image capturing time, and since the at least one first captured image and the second captured image respectively represent different capturing scenes, the continuous output file may represent a transition between the different capturing scenes, that is, a more real and stronger look and feel may be formedThe effect of dithering.
According to the embodiment of the disclosure, the preset time interval can be set according to actual needs, if the preset time interval is smaller, the jitter frequency is higher, and if the preset time interval is larger, the jitter frequency is lower. The offset distance and the offset direction of any two target positions in the plurality of target positions with respect to the initial position may be different, and may be set as needed. For example, a distribution curve of a target position sequence composed of a plurality of target positions follows the law of a sine wave (sine wave). The offset distance and the offset direction of the multiple movements of the lens are performed according to the rule of a sine curve. In the case where the preset time interval is small, a shake effect in which the photographic subject moves as a ripple appears in the continuous output file can be seen. For another example, a distribution curve of a target position sequence composed of a plurality of target positions conforms to the rule of a conic section (conic section), such as a circle, an ellipse, and the like. The offset distance and the offset direction of the lens moving for many times are performed according to the rule of a conical curve, and when the circular rule is met, the offset distances of the lens moving for many times are the same, but the offset directions of the lens moving for many times are different.
According to an embodiment of the present disclosure, when a user takes an image using an electronic device and desires to obtain a continuous output image having a shake effect, the above-described information processing process may be performed based on a trigger instruction of the user. Illustratively, the obtaining the target position includes: and acquiring a trigger instruction, and determining a video acquisition mode corresponding to the trigger instruction. The video capture mode is used to characterize an offset distance and direction of each of the at least one target location relative to the initial location. Then, respective coordinates of the at least one target location are determined based on the video capture mode. Furthermore, in other embodiments, the video capture mode is further used to characterize at least one of: a preset time interval and at least one acquisition position.
The above embodiments exemplify a process of obtaining a multimedia file having a dithering effect by controlling mechanical movement of a lens and image capturing in a camera module of an electronic device, and the control principle thereof is exemplified below with reference to the embodiments.
According to an embodiment of the present disclosure, the camera module of the electronic device may further include an Optical anti-shake system, which may also be referred to as an Optical Image Stabilization (OIS) system. The initial aim at that sets up optics anti-shake system in the camera module realizes optics anti-shake.
Fig. 4A schematically illustrates an example block diagram of an optical anti-shake system according to an embodiment of this disclosure.
As shown in fig. 4A, the optical anti-shake system 410 of the camera module 400 may include a gyroscope (gyro)411, a microcontroller (microcontroller)412, a hall sensor (hall sensor)413, and a driver (driver) 413. The gyroscope 411 is used for detecting the pose change of the camera module caused by vibration or shake and transmitting the pose change to the microprocessor 412. The microprocessor 412 thus calculates the amount of displacement to be compensated and sends instructions to the driver 414. The driver 414 is used for driving the lens to move according to the instruction of the microprocessor. The hall sensor 413 is used for measuring the moving position of the lens in the camera module 400 and feeding back the moving position to the microprocessor 412.
Fig. 4B schematically illustrates an example schematic diagram of a closed control circuit of an optical anti-shake system according to an embodiment of the disclosure.
As shown in fig. 4B, the gyroscope (Gyro)411 measures the pitch angular velocity ω based on the x-axis and the y-axis of the camera module 400, respectivelypitchAnd yaw rate ωyawAnd input to the microcontroller 412. The microcontroller 412 may include an integration circuit 4121, a compensation calculation circuit 4122, and a controller 4123. Pitch angle rate omegapitchAnd yaw rate ωyawThe pitch angles theta are respectively obtained through an integrating circuit 4121pitchAnd yaw angle thetayawAnd input to the compensation calculation circuit 4122.

The controller 4123 issues a command to the driver 414 according to the compensation displacements in the x-axis and the y-axis to cause the driver 414 to drive the lens to move by the corresponding compensation displacements in the x-axis and the y-axis, respectively, based on the command. Please refer to fig. 4C for the body coordinate system o-xyz of the camera module 400.
Fig. 4C schematically illustrates an example schematic diagram of a body coordinate system of a camera module according to an embodiment of the disclosure. As shown in FIG. 4C, the Pitch (Pitch) angle θpitchFor angles of rotation about the x-axis, the Yaw (Yaw) angle θyawThe Roll (Roll) angle of rotation about the z-axis is also shown for the angle of rotation about the y-axis. The example shown in fig. 4B is not mentioned because small changes in roll angle have little effect on the shot capture scene.
Fig. 4D schematically illustrates an example schematic of a camera module according to an embodiment of this disclosure. As shown in fig. 4D, the lens 420 can move in a receiving space of the camera module 400, and the lens 420 is disposed in the receiving space through a plurality of springs (springs) 430. Driver 414 may include a magnet (magnet)4141 and a coil (coil) 4142. The displacement of the lens 420 is controlled by controlling the magnitude and direction of the current in each coil 4142 to control the distance between each pair of opposing magnets 4141 and coils 4142.
The above process may be called an adaptive mode of the optical anti-shake system, and adaptive compensation and adjustment are performed on shaking conditions of a user who uses the electronic device to perform shooting, such as breathing, heartbeat, and involuntary body shaking. In addition to the adaptive mode, the optical anti-shake system can be set to a control mode in which the instruction output by the microcontroller can be adjusted directly by an active input to the microcontroller. Thereby causing the driver to perform a driving process according to the instruction.
Based on the principle, the optical anti-shake system in the camera module can drive the lens to move towards all directions and detect the moving position of the lens in real time. According to the embodiment of the disclosure, the information processing method according to the embodiment of the disclosure can be implemented by using the optical anti-shake system without changing the hardware configuration of the camera module.
For example, the process of controlling the lens in the camera module to move from the initial position to the target position may include: the optical anti-shake system is switched from the adaptive mode to the control mode. Then, the coordinates of the target position are acquired. Then, the coordinates of the target position are sent to the optical anti-shake system, so that the controller in the optical anti-shake system generates an instruction for the coordinates of the target position and sends the instruction to the driver, and the driver controls the lens to move from the initial position to the target position based on the instruction. In the process of controlling the lens to return from the target position to the initial position, the optical anti-shake system may be switched from the control mode to the adaptive mode, so that the optical anti-shake system controls the lens to return from the target position to the initial position based on the above-mentioned operating principle in the adaptive mode.
For example, the process of controlling the lens to return from the target position to the initial position may include: the optical anti-shake system uses the gyroscope to obtain the deflection parameters (which may include the pitch angle and the yaw angle, for example) of the camera module, and uses the hall sensor to obtain the position of the lens relative to the camera module. And then, determining an initial position by using the microprocessor according to the deflection parameter of the lens and the position of the lens relative to the camera module. Then, the lens is controlled to move to the initial position by the driver.
