Based on the above mobile terminal hardware structure and communication system, various embodiments of the present invention are proposed.
An embodiment of the present invention provides an anti-shake processing method, which, as shown in fig. 3, includes the following steps:
Here, the terminal may be a mobile terminal having a photographing function, a video monitoring apparatus, a handheld video camera, a digital camera, or the like. The camera includes a motion Sensor, a Central Processing Unit (CPU), an Image Sensor (IS), and an Image Signal Processor (ISP). The anti-shake processing method provided by the embodiment of the invention is a picture compensation mode which can cause unstable and drifting of an output image due to large-amplitude shake of a lens in the video shooting process or the preview process of a camera.
In order to compensate the camera shake, the camera of the terminal firstly acquires the motion information of the camera through a motion sensor, so that the camera determines to correspondingly compensate the output of a video picture, namely an output image according to the motion information, and further avoids the output image from drifting.
The motion sensor acquires motion information of the camera in real time, and the CPU acquires the motion information acquired by the motion sensor in real time. For example, the motion information includes: the angle of the camera, the direction of motion of the camera, etc. Of course, the motion information may also include other information, and the embodiment of the present invention is not particularly limited to this.
The preset angle may represent a field angle of a lens of the camera as 1 degree. Of course, the preset angle may be set according to actual conditions, so as to implement the anti-shake processing method provided by the present invention.
In an embodiment of the present invention, the motion sensor may include: acceleration sensors and gyroscope sensors, in which case the motion sensor can determine the angle of the camera in the following manner.
The method comprises the steps that a CPU obtains the acceleration of a first preset sampling point in a first preset time, wherein the acceleration is collected by an acceleration sensor, and whether a camera is in a static state or not is judged according to the acceleration of the first preset sampling point and a preset static threshold; if the acceleration of the first preset sampling point is larger than the preset static threshold value, the CPU obtains the angular velocity of a second preset sampling point within second preset time collected by the gyroscope sensor, multiplies the angular velocity of the second preset sampling point by the second preset time, and determines the angle of the camera, namely the rotation angle.
In the embodiment of the invention, from the direction of motion, the lens of the camera can move up, down, left, right, rotation and the like, the CPU obtains the acceleration of a first preset sampling point in a first preset time collected by an acceleration sensor, and judges whether the camera is in a static state or not by comparing the acceleration of the first preset sampling point with a preset static threshold; if the acceleration of the first preset sampling point is smaller than the preset static threshold, the CPU determines that the motion of the camera is very weak and the jitter generated on the video picture is small, and at the moment, the camera is determined to be approximately in a static state; if the acceleration of the first preset sampling point is larger than the preset static threshold, the CPU determines that the motion of the camera can cause the shake generated by the video picture to be larger, and at the moment, determines that the camera is in a non-static state; it should be noted that the preset static threshold is an empirical value.
Further, the CPU obtains the angular velocity of a second preset sampling point in second preset time collected by the gyroscope sensor, multiplies the angular velocity of the second preset sampling point in the second preset time by the second preset time, and determines the rotation angle of the camera in the second preset time. For example, the rotation angle includes a rotation angle Ax along the X-axis and a rotation angle Ay along the Y-axis, which may be expressed as (Ax, Ay).
The method comprises the steps that a camera is collected at a terminal to move, and when a first angle corresponding to the movement is larger than a preset angle, the terminal obtains a first direction and a first displacement when the camera moves.
In practical application, for example, taking a terminal as a mobile phone with a shooting function, as shown in fig. 4, in a process that a user uses the mobile phone to shoot a shooting object such as a person in fig. 4, the user first starts a camera function of the mobile phone, and at this time, the shooting object can be seen on a display screen of the terminal, that is, a shooting interface. Assuming that the mobile phone IS not moving at this time, the user can see a clearer image from the shooting interface, where the image IS an output image of the IS, and the output image may be a partial image of the current frame image.
Further, when the user's hand is unintentionally shaken, and if the user shakes the camera upward, the lens of the camera correspondingly shakes upward, for example, the lens rotates upward by 2 degrees, and since the angle is larger than a preset angle, for example, 1 degree, the lens performs a downward compensation action. As shown in fig. 5, the user can see the output image drifting downward from the shooting interface.
As the lens of the camera can move up, down, left, right, and rotate, for example, as shown in fig. 6, when the hand of the user shakes unconsciously, assuming that the camera shakes in all four directions, i.e., up, down, left, right, and left directions, in the vertical plane, the lens of the camera also shakes correspondingly in all four directions, i.e., up, down, left, and right, and the shake angle is greater than the preset angle, then the lens performs the maximum compensation for the shake, and at this time, the user can see that the output image drifts in the four directions, i.e., up, down, left, and right.
The anti-shake processing method provided by the invention is just for the shake of which the angle of the lens of the camera is larger than the preset angle, and the phenomenon that the output image drifts when the lens performs larger compensation action is inhibited, so that the mobile phone can control the stable display effect of the output image in the shooting interface even if the angle of the lens of the camera is larger than the shake of the preset angle.
The first image is an output image of an image sensor of the camera, and the second direction is different from the first direction.
Here, the second direction is opposite to the first direction. After the terminal acquires the first direction and the first displacement, the lens of the camera is adjusted to a first position in a second direction opposite to the first direction, such as downward, the first position being a maximum position at which the lens is deflected downward. That is, at this time, the lens of the terminal makes the maximum inverse compensation for the motion corresponding to the first angle that occurs. Meanwhile, the terminal controls the first image to move upwards so as to make the maximum upward compensation, so that the phenomenon that the first image drifts downwards due to the large-amplitude rotation of the lens is avoided.
The first target position and the second target position have a corresponding relation.
Here, after the terminal controls the lens to make the reverse maximum compensation in the second direction, the terminal further adjusts the lens, adjusts the lens from the first position to the first target position in the direction opposite to the second direction, and adjusts the first image from the second position to the second target position in the second direction, where the second target position refers to the central region position of the lens field.
And 304, displaying the first image on a display screen of the terminal based on the second target position.
Here, the first image is displayed at the second target position, i.e., the central region position of the lens field of view, on the display screen of the terminal.
According to the anti-shake processing method provided by the embodiment of the invention, if the camera of the terminal is in a working state and the first angle of the camera is larger than the preset angle, the first direction and the first displacement when the camera moves at the first angle are obtained; adjusting the lens of the camera to a first position along a second direction, and adjusting the first image to a second position along a direction opposite to the second direction; the first image is an output image of an image sensor of the camera, and the second direction is different from the first direction; adjusting the lens from the first position to the first target position along the direction opposite to the second direction, and adjusting the first image from the second position to the second target position along the second direction; the first target position and the second target position have a corresponding relation; and displaying the first image on a display screen of the terminal based on the second target position. That is to say, if the camera is in a working state, and the camera moves and the angle of the camera is greater than the preset angle, the terminal controls the lens of the camera to perform shake compensation for the motion, and simultaneously performs corresponding adjustment on the position of the first image, so that the position of the first image is correspondingly adjusted along with the movement of the lens, and thus the first image output on the display screen of the terminal cannot drift; the problem that in the prior art, if the camera of the intelligent terminal shakes by more than a preset angle, the lens of the camera cannot perform corresponding compensation action, so that the output image drifts is solved; the output image drift phenomenon caused by camera shake is effectively avoided, the display effect of the terminal is improved, and meanwhile, the intelligence of the terminal is improved.
Based on the foregoing embodiments, an embodiment of the present invention provides an anti-shake processing method, which is shown in fig. 7 and includes the following steps:
Here, step 701 may include:
step one, if the camera is in a working state, acquiring a third position of the first image when the camera does not move for the first time.
Here, the third position of the first image generally refers to the central region position of the lens field of view when the first motion of the camera has not occurred.
And secondly, if the camera moves for the first time, acquiring a fourth position of the first image and a first direction corresponding to the first movement when the first movement occurs.
Here, the moving direction of the lens of the camera may be detected by the gyro sensor.
In an embodiment of the present invention, the motion sensor may include: a gyroscope sensor. And the CPU acquires the angular velocity of a third preset sampling point within third preset time acquired by the gyroscope sensor, multiplies the angular velocity of the third preset sampling point by the third preset time, and determines the rotation angle of the camera.
In the embodiment of the invention, a CPU directly obtains the angular velocity of a third preset sampling point in a third preset time acquired by a gyroscope sensor, multiplies the angular velocity of the third preset sampling point in the third preset time by the third preset time, determines the rotation angle of the camera in the third preset time, and if the rotation angular velocity of the camera in the third preset time is 0, the CPU determines that the camera is static in the third preset time; if the rotational angular speed of the camera in the third preset time is not 0, the CPU determines that the camera has rotated in the third preset time, and the rotational angle comprises a rotational angle Ax along the X axis and a rotational angle Ay along the Y axis, and the rotational angle can be expressed as (Ax, Ay).
It can be seen that the motion sensor in the embodiment of the present invention may include an acceleration sensor and a gyroscope sensor, or only include a gyroscope sensor, which may both acquire the angle when the camera moves.
And thirdly, obtaining a first displacement amount based on the third position and the fourth position.
Here, the CPU acquires the real-time position of the IS output image. For example, a third position when no movement has occurred and a fourth position after movement has occurred. Further, the CPU calculates a displacement amount of the first image, that is, a first displacement amount, based on the third position and the fourth position.
Wherein the second displacement amount is greater than or equal to the first displacement amount.
Here, the second displacement amount may be a maximum displacement amount by which the lens is moved to the second direction, that is, the terminal controls the lens to make a maximum reverse compensation for the occurrence of the first motion.
Wherein the third displacement is less than the second displacement.
Here, the third displacement amount is a displacement amount for indicating that the lens is returned to the center position. That is, the terminal controls the lens to return to the center position after controlling the lens to make the maximum reverse compensation for the first motion that occurs, i.e., the position of the lens when it is in a stationary state before the motion occurs.
And step 704, displaying the first image on a display screen of the terminal based on the second target position.
It should be noted that, for the descriptions of the same steps and the same contents in this embodiment as those in other embodiments, reference may be made to the descriptions in other embodiments, which are not described herein again.
The anti-shake processing method provided by the embodiment of the invention solves the problem that in the prior art, if the camera of the intelligent terminal shakes by more than a preset angle, the lens of the camera cannot perform corresponding compensation action, so that the output image drifts; the output image drift phenomenon caused by camera shake is effectively avoided, the display effect of the terminal is improved, and meanwhile, the intelligence of the terminal is improved.
Based on the foregoing embodiments, an embodiment of the present invention provides an anti-shake processing method, which is shown in fig. 8 and includes the following steps:
The first image is an output image of an image sensor of the camera, and the second direction is different from the first direction.
Wherein the first target position and the second target position have corresponding relationship
And step 804, displaying the first image on a display screen of the terminal based on the second target position.
When the terminal detects that the lens shakes greatly, namely the angle of the camera IS larger than the preset angle, and the lens has a large reverse compensation action for the large-amplitude shake, in order to avoid the output image of the IS from drifting, the terminal controls the output image to carry out maximum compensation in the direction opposite to the lens, and after the terminal IS stabilized, the lens and the output image are controlled to return to the central position, namely the position of the output image before the shake occurs. In this way, the terminal can compensate for the large jitter.
And 805, if the second angle of the second movement of the camera is smaller than the preset angle, acquiring a third direction and a fourth displacement when the lens moves at the second angle.
Wherein the fourth displacement is less than the first displacement.
Here, after the lens largely shakes and the shake is suppressed, if the terminal detects that the camera shakes again, that is, moves for the second time, and the second angle corresponding to the shake is smaller than the preset angle, then the terminal does not need to control the lens to perform the maximum reverse compensation, and only needs to control the lens and the output image to perform the motion compensation corresponding to the second motion, so that the current small-amplitude shake can be suppressed.
Wherein the third direction is different from the fourth direction.
Step 807 displays the first image on the display screen based on the fourth target position.
Here, after the terminal suppresses the shake of a small amplitude, the output position of the first image, that is, the fourth target position is determined, and the first image is displayed on the display screen based on the fourth target position.
It should be noted that, for the descriptions of the same steps and the same contents in this embodiment as those in other embodiments, reference may be made to the descriptions in other embodiments, which are not described herein again.
