Detailed Description
The technical solutions of the embodiments of the present application will be clearly described below with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which are obtained by a person skilled in the art based on the embodiments of the present application, fall within the scope of protection of the present application.
The terms first, second and the like in the description and in the claims, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used may be interchanged, as appropriate, such that embodiments of the present application may be implemented in sequences other than those illustrated or described herein, and that the objects identified by "first," "second," etc. are generally of a type, and are not limited to the number of objects, such as the first object may be one or more. Furthermore, in the description and claims, "and/or" means at least one of the connected objects, and the character "/", generally means that the associated object is an "or" relationship.
The optical anti-shake method provided by the embodiment of the application is described in detail below through specific embodiments and application scenarios thereof with reference to the accompanying drawings.
In the related art, a camera generally utilizes active OIS to realize optical anti-shake, where the camera generally includes an OIS module, the OIS module may include an OIS component and a lens, the lens is located in the OIS component, and the OIS component may control movement of the lens to realize optical anti-shake. Active OIS relies on 1 OIS component to control the lens to be pulled back to the central position during the idle time of exposure. As shown in fig. 1, the total time (total) for capturing one frame of image at the camera is T, for example, 30 frames per second (fps), and t=1/30≡33.3ms.
Optionally, one T includes: exposure time, readout time of rolling shutter (readout time), and idle time (vblank time). The idle time is understood as the time that the OIS module can control the lens to return to the middle, in other words, the time that the OIS module performs the return to the middle operation.
Based on fig. 1, it can be seen that, if the duration of T is equal to the sum of the exposure time, readout time and vblank time, and if the exposure time is readout time and is constant, when T is very short, the idle time is very short, the time for the OIS module to perform the centering operation is very short, the lens cannot be controlled to be fully centered, and the next frame (such as the n+1st frame) is about to start exposure, so that the available anti-shake stroke of the OIS module is very small, and the anti-shake effect is poor. In order to solve this problem, an optical anti-shake method of the present application is proposed.
Referring to fig. 2, an embodiment of the present application provides an optical anti-shake method, which is applied to an electronic device, where the electronic device includes a first optical anti-shake module and a second optical anti-shake module, as shown in fig. 2, and the optical anti-shake method includes:
step 201, the electronic device receives shooting input of a user;
in the embodiment of the application, the electronic equipment can provide an interactive interface for a user to carry out shooting input, and is used for sending a control command to the electronic equipment through other electronic equipment so as to realize shooting input, and in addition, shooting input can be realized through voice or gesture modes and the like. The specific input form is not further limited herein.
In step 202, the electronic device controls the first optical anti-shake module and the second optical anti-shake module to switch to execute the optical anti-shake operation in response to the photographing input.
Optionally, the first optical anti-shake module and the second optical anti-shake module may be OIS modules with the same model and parameters, or may be different, which is not limited herein.
In the embodiment of the present application, controlling the first optical anti-shake module and the second optical anti-shake module to switch and execute the optical anti-shake operation may be understood as controlling the first optical anti-shake module and the second optical anti-shake module to execute the optical anti-shake operation on the light passing through the light inlet channel at different times. Optionally, during the shooting process, the first optical anti-shake module and the second optical anti-shake module may be periodically switched to perform an optical anti-shake operation on the light passing through the light inlet channel. For example, the optical anti-shake operation is performed on the light passing through the light-incoming channel by the first optical anti-shake module in the odd-numbered periods, and the optical anti-shake operation is performed on the light passing through the light-incoming channel by the second optical anti-shake module in the even-numbered periods.
As shown in fig. 3, the light inlet channel 301 is located in front of the first optical anti-shake module 302 and the second optical anti-shake module 303, and external light can enter the first lens 3021 of the first optical anti-shake module 302 and/or the second lens 3031 of the second optical anti-shake module 303 through the light inlet channel 301 and reach the photosensitive chip 304 through the first lens 3021 of the first optical anti-shake module 302 and/or the second lens 3031 of the second optical anti-shake module 303.
It should be noted that, the positional relationship between the first optical anti-shake module 302 and the second optical anti-shake module 303 may be set according to actual needs. For example, in the first embodiment, the first optical anti-shake module 302 and the second optical anti-shake module 303 may be disposed in parallel, and a switching device 307 for controlling optical path switching may be disposed between the light-in path 301 and the first optical anti-shake module 302 and the second optical anti-shake module 303, and by this switching device 307, the light-in path 301 may be controlled to reach the photosensitive chip 304 only through the first lens 3021 of the first optical anti-shake module 302 or the second lens 3031 of the second optical anti-shake module 303. As shown in fig. 3, the first optical anti-shake module 302 and the second optical anti-shake module 303 may be disposed at different positions perpendicular to the plane of the light-incoming channel 301. It should be understood that, when the first optical anti-shake module and the second optical anti-shake module adopt the position structures corresponding to the first embodiment, in order to make the light emitted by the first optical anti-shake module and the second optical anti-shake module better incident on the photosensitive chip, a first light guide may be disposed between the first optical anti-shake module and the photosensitive chip, and a second light guide may be disposed between the second optical anti-shake module and the photosensitive chip. In the following examples, the first optical anti-shake module and the second optical anti-shake module are described using the position structures corresponding to the first embodiment.
In the second embodiment, the first optical anti-shake module 302 and the second optical anti-shake module 303 may be stacked, and at this time, the light in the light-incoming channel 301 can sequentially pass through the first lens 3021 of the first optical anti-shake module 302 and the second lens 3031 of the second optical anti-shake module 303 to reach the photosensitive chip 304. It should be understood that when the position structure corresponding to the second embodiment is adopted, a compensation component may be further disposed between the optical anti-shake module and the photosensitive chip, where the compensation component may adopt a structure similar to the OIS module, and is configured to eliminate the influence of one optical anti-shake module on light when the other optical anti-shake module performs the optical anti-shake operation.
Alternatively, in some embodiments, when shooting is started, the first optical anti-shake module may perform the optical anti-shake operation first, and after a period of time, the second optical anti-shake module performs the optical anti-shake operation, and then performs the reciprocating switching according to a certain period. In the shooting process, the first optical anti-shake module can execute the back-in operation in the process of executing the optical anti-shake operation by the second optical anti-shake module besides executing the back-in operation in the idle time; similarly, the second optical anti-shake module may perform the centering operation during the optical anti-shake operation of the first optical anti-shake module in addition to performing the centering operation during the idle time. Therefore, the anti-shake effect can be improved and the shooting quality can be improved due to the fact that the time for returning is prolonged.
In step 203, the electronic device displays a preview screen shot based on the anti-shake operation.
Optionally, the electronic device may provide a shooting preview interface, through which a shot preview image is displayed in real time during shooting, so as to show an effect of a shot video, and facilitate user viewing and subsequent shooting processing.
According to the embodiment of the application, the optical anti-shake operation is performed by controlling the switching of the first optical anti-shake module and the second optical anti-shake module, so that the time of the return operation can be prolonged. Therefore, the embodiment of the application improves the anti-shake effect and improves the shooting quality.
Optionally, in some embodiments, the controlling the first optical anti-shake module and the second optical anti-shake module to switch performs the optical anti-shake operation includes:
Controlling the first optical anti-shake module to execute optical anti-shake operation on light passing through the light inlet channel when an N frame image is shot;
controlling the second optical anti-shake module to execute optical anti-shake operation on light passing through the light inlet channel when shooting an n+1st frame image;
and the light in the light inlet channel can be incident to the first lens of the first optical anti-shake module and/or the second lens of the second optical anti-shake module and is incident to the photosensitive chip through the first lens of the first optical anti-shake module and/or the second lens of the second optical anti-shake module.
In the embodiment of the application, the second optical anti-shake module can execute the centering operation when the N-th frame image is shot, and the first optical anti-shake module can execute the centering operation when the N+1-th frame image is shot. Therefore, the optical anti-shake module is switched when each frame of image is shot, so that the anti-shake effect of each frame can be ensured, and the overall shooting effect is further improved.
It should be noted that, in some embodiments, when any frame of image is captured, the light passing through the light inlet channel may simultaneously pass through the first lens of the first optical anti-shake module and the second lens of the second optical anti-shake module to be incident on the photosensitive chip.
In some embodiments, when the nth frame of image is captured, the light passing through the light inlet channel may be incident on the photosensitive chip only through the first lens of the first optical anti-shake module; when shooting an n+1th frame of image, the light passing through the light inlet channel can only enter the photosensitive chip through the second lens of the second optical anti-shake module. For example, before controlling the first optical anti-shake module to perform an optical anti-shake operation on the light passing through the light inlet channel when the nth frame image is captured, the method further includes:
Light passing through the light inlet channel is subjected to light path switching, so that the light passing through the light inlet channel is incident to a first lens of the first optical anti-shake module and is incident to a light sensing chip after passing through the first lens of the first optical anti-shake module;
After controlling the first optical anti-shake module to perform an optical anti-shake operation on the light passing through the light inlet channel when the nth frame image is captured, the method further includes:
And switching optical paths of the light rays passing through the light inlet channel, so that the light rays passing through the light inlet channel are incident to the second lens of the second optical anti-shake module and are incident to the light sensing chip after passing through the second lens of the second optical anti-shake module.
In the embodiment of the present application, as shown in fig. 3, the first optical anti-shake module 302 is disposed on the first optical path 305, and the second optical anti-shake module 303 is disposed on the second optical path 306. In some embodiments, the first optical anti-shake module 302 and the second optical anti-shake module 303 may be controlled to move to achieve optical path switching. In some embodiments, a switching device 307 for controlling the light path switching may be further disposed between the light inlet channel 301 and the first optical anti-shake module 302 and the second optical anti-shake module 303, and the switching device 307 may change the direction of the light, so that the light passing through the light inlet channel 301 is incident to the first lens 3021 of the first optical anti-shake module 302 or the second lens 3031 of the second optical anti-shake module 303.
Because the light path is switched, the light passing through the light inlet channel is incident to the first lens of the first optical anti-shake module or the second lens of the second optical anti-shake module, namely, the light passing through the light inlet channel is incident to the photosensitive chip through only one optical anti-shake module, so that the processing difficulty of the light can be simplified, the structure of a product is simplified, and the industrial production is facilitated.
In the embodiment of the present application, the time for performing the optical path switching may be set according to actual needs. For example, in some embodiments, the shooting time of each frame of image includes an exposure time, a readout time of a shutter, and an idle time, and the optical path switching of the light passing through the light-entering channel includes:
And carrying out optical path switching on the light passing through the light inlet channel at a target moment, wherein the target moment is in the time range of the idle time.
In the embodiment of the present application, the target time may be a start time of the idle time, so that the idle time of the nth frame, the exposure time of the n+1th frame, and the readout time of the shutter of the n+1th frame may all control the first optical anti-shake module to perform the back-to-center operation; the first optical anti-shake module may be controlled to perform the back-in operation during the idle time of the n+1st frame, the exposure time of the n+2nd frame, and the readout time of the shutter of the n+2nd frame. At this time, the time for performing the back-in operation of the optical anti-shake module may be the total time of one frame, so that the embodiment of the application may extend the time for performing the back-in operation of the optical anti-shake module to the maximum extent, thereby further improving the anti-shake effect.
It should be noted that, in the embodiment of the present application, the operation of performing the centering operation of the optical anti-shake module may be specifically understood as controlling the corresponding lens centering operation of the optical anti-shake module. The optical anti-shake module performs an optical anti-shake operation, which can be understood as that the optical anti-shake module controls the corresponding lens to move up/down from the middle point to suppress or compensate motion blur, so that the image displayed on the sensing chip always maintains a stable state.
For example, as shown in fig. 4, at the start of operation, the light in the light-incoming channel 301 reaches the photosensitive chip through the first optical path 305 under the control of the switching device 307. At the exposure time, the first optical anti-shake module 302 controls the first lens 3021 of the first optical anti-shake module 302 to move upward/downward (i.e., the first optical anti-shake module 302 performs an optical anti-shake operation) to suppress and compensate for motion blur. After the exposure time and readout time are finished, when vblank time is reached, the first optical anti-shake module 302 controls the first lens 3021 of the first optical anti-shake module 302 to move from the upper/lower direction to the middle point (i.e., the first optical anti-shake module 302 performs a centering operation). In the case of vblank time having a short period of time, since the second lens in the first optical anti-shake module 302 is not completely retracted, the exposure of the next frame (e.g., the n+1st frame) is started, and then the optical path switching can be controlled. For example, as shown in fig. 5, the light in the light inlet channel 301 passes through the second light path 306 and reaches the photosensitive chip under the control of the switching device 307, at this time, the first optical anti-shake module 302 continues to control the first lens in the first optical anti-shake module 302 to move from the upper/lower direction to the middle point, and at the exposure time of the next frame, the second optical anti-shake module 303 controls the second lens 3031 in the second optical anti-shake module 303 to move to implement the anti-shake operation.
It should be understood that the bold dashed lines in fig. 4 and 5 indicate that the current optical path through which light can reach the light sensing chip is in a pass-through state.
Optionally, in some embodiments, before the controlling the first optical anti-shake module and the second optical anti-shake module to switch to perform the optical anti-shake operation, the method further includes:
Acquiring shooting parameters, wherein the shooting parameters comprise exposure time, readout time of a shutter and shooting frame rate;
Determining a target duration based on the exposure time, the readout time of the shutter and the shooting frame rate, wherein the target duration is used for representing the duration of executing the back-to-center operation of the first optical anti-shake module or the second optical anti-shake module;
determining an anti-shake working mode according to the target duration;
wherein the anti-shake operation mode satisfies at least one of:
When the target time length is greater than a preset threshold value, the anti-shake working mode is a first mode, in the first mode, optical anti-shake module switching is not performed, and any one of the first optical anti-shake module and the second optical anti-shake module executes optical anti-shake operation;
And when the target duration is smaller than or equal to the preset threshold value, the anti-shake working mode is a second mode, and in the second mode, the first optical anti-shake module and the second optical anti-shake module are switched to execute optical anti-shake operation.
In the embodiment of the application, different shooting parameters can be set based on different shooting scenes, the shooting parameters can be set actively by a user, and the shooting parameters can also be set automatically based on the shooting scenes, and the method is not limited further.
Alternatively, the above target period may be understood as an idle period, which is equal to the total time to take a frame of image minus the exposure time and the readout time of the shutter. The magnitude of the preset threshold may be set according to actual needs, for example, in some embodiments, the value range of the preset threshold may be 5ms to 8ms.
Because in the embodiment of the application, the target duration is determined first, and then the anti-shake working mode is determined based on the target duration, the first optical anti-shake module or the second optical anti-shake module can be used for executing the optical anti-shake operation under the condition that the target duration is longer, so that the loss of electric quantity can be reduced. Under the condition that the target duration is short, the first optical anti-shake module and the second optical anti-shake module are used for switching and executing the optical anti-shake operation, so that the overall shooting quality is improved.
It should be noted that, in the optical anti-shake method provided by the embodiment of the present application, the execution body may be an optical anti-shake device, or a control module for executing the optical anti-shake method in the optical anti-shake device. In the embodiment of the application, an optical anti-shake method performed by an optical anti-shake device is taken as an example, and the optical anti-shake device provided by the embodiment of the application is described.
