Therefore, reducing the operation complexity of image acquisition and improving the imaging effect become problems to be solved urgently in the image acquisition process.
Based on the foregoing, an embodiment of the present application provides an image capturing method applied to an electronic device having a front camera and a rear camera, and referring to fig. 1, the method includes the following steps:
In the embodiment of the present application, the electronic device may include a mobile terminal device such as a mobile phone, a tablet computer, a notebook computer, a Personal Digital Assistant (PDA), a camera, a wearable device, and a fixed terminal device such as a desktop computer. It can be understood that the viewing directions of the rear camera and the front camera of the electronic device are different, that is, the viewing direction of the rear camera and the viewing direction of the front camera form a certain angle; for example, the viewing direction of the rear camera and the viewing direction of the front camera are 180 degrees, and the viewing direction of the rear camera and the viewing direction of the front camera are opposite.
In the embodiment of the application, the first image comprises an image which is acquired by a front camera in real time and is associated with an operator of the electronic equipment, namely a photographer; the first information includes information associated with an action of an operator.

And 102, if the first information accords with first preset information, controlling a rear camera of the electronic equipment to acquire an image.
In the embodiment of the application, the first preset information and the first information have the same information type; for example, when the first information includes facial motion information and/or gesture motion information of an operator of the electronic device, the first preset information includes preset facial motion information and/or preset gesture motion information. Here, the first information conforming to the first preset information may represent that the first information is identical to the first preset information. And controlling the rear camera to acquire images, wherein the control can comprise controlling the rear camera to photograph or make a video and the like.

In the embodiment of the application, the opening time of the front camera and the rear camera of the electronic equipment can be flexibly controlled; for example, the electronic device may turn on the front camera and the rear camera at the same time; for example, the electronic device may turn on the front camera first and then turn on the rear camera; for another example, the electronic device may turn on the rear camera first and then turn on the front camera.
In a first implementation scenario, the electronic device may acquire a first image through the front camera under the condition that the front camera and the rear camera are simultaneously turned on, acquire first information associated with an action of an operator in the first image, and control the rear camera to acquire the image under the condition that the first information conforms to first preset information.
In a second implementation scenario, when a front camera of an electronic device is in an open state, a rear camera of the electronic device is opened, and then a first image is acquired through the front camera, first information associated with an action of an operator in the first image is acquired, and then the rear camera is controlled to acquire the image under the condition that the first information conforms to first preset information.
In a third implementation scenario, under the condition that a rear camera of an electronic device is in an open state, the front camera of the electronic device is opened, a first image is collected through the front camera, first information related to the action of an operator in the first image is acquired, and then the rear camera is controlled to collect the image under the condition that the first information accords with first preset information. Here, for example, when the viewing direction of the rear camera is opposite to the viewing direction of the front camera, the electronic device turns on the front camera while an operator of the electronic device, i.e., a photographer, uses the rear camera of the electronic device to capture a beautiful scene, and at this time, the viewing direction of the front camera faces the photographer, so that the first image can be captured, facial movement information of the photographer and the like can be acquired based on the first image, and the rear camera is controlled to capture the image when the facial movement feature information conforms to the first preset information.

Based on the foregoing embodiments, an embodiment of the present application provides an image capturing method, which is applied to an electronic device having a front camera and a rear camera, and as shown in fig. 2, the method includes the following steps:
In this embodiment of the application, the first preview interface refers to a shooting interface of the rear camera in an open state of the rear camera. In practical application, under the condition that the electronic equipment starts the rear camera of the electronic equipment, a first preview interface corresponding to the rear camera is displayed on a display screen of the electronic equipment, so that an operator of the electronic equipment can determine final image acquisition content according to the content of the first preview interface.
In the embodiment of the application, the second information has an association relation with the first preview interface; for example, the second information may include information related to an object displayed in the first preview interface; the second information may also include information related to imaging parameters of the first preview interface. It is to be understood that, when the second information includes information related to the imaging parameters of the first preview interface, the second information may be displayed in the first preview interface as one of the objects displayed in the first preview interface.
And 203, if the second information accords with second preset information, starting the front camera.
In the embodiment of the application, the second preset information can be understood as a trigger condition for starting the front camera; the second information is the same as the second preset information in information type. Here, the second information may represent that the second information is the same as the second preset information in conformity with the second preset information. That is to say, under the condition that the electronic equipment opens the rear camera and the display screen of the electronic equipment displays the first preview interface corresponding to the rear camera, the detected second information associated with the first preview interface can be utilized, the second information conforms to the second preset information, and the opening of the front camera is triggered, so that the flexible control of the camera of the electronic equipment is realized, and meanwhile, the intelligent degree of the electronic equipment is improved.
In this embodiment of the application, if the second information matches the second preset information, the front camera is turned on in step 203, which can be implemented in the following two ways:
in a first manner, the first preview interface includes a first control for opening the front camera, and at this time, if the second information represents the touch operation for the first control, it is determined that the second information conforms to the second preset information, and the front camera is opened.
Here, the second information may be understood as information related to an object displayed in the first preview interface, such as the first control; further, the second information may be understood as touch operation information related to the first control displayed in the first preview interface.
In the embodiment of the application, when the electronic device opens the rear camera, an operator of the electronic device may perform touch operation on a first control in a first preview interface displayed on a display screen, and then the electronic device acquires the touch operation for the first control to generate second information, and then determines that the second information conforms to second preset information, and opens the front camera.
In practical application, the first control can be displayed on the first preview interface in the form of a specific identifier; the specific mark may include a micro expression mark such as a smiley face, a slide button, and the like, which is not particularly limited in this application.
When the rear camera is used, the front camera is used to acquire facial motion information of an operator of the electronic device, namely a photographer, wherein the facial motion information can be called micro expression, and the rear camera is controlled, so that shake in the shooting process of the rear camera can be reduced, and the imaging effect can be improved.
Illustratively, micro-expressions can be divided into two categories: the first type is default setting of the electronic equipment before leaving factory, such as smiling, blinking, beeping mouth and the like; the second type is the expression which is input by the user in a self-defining way. The second type of expression can be subjected to feature matching by acquiring images on a preview interface through a specific algorithm, and after the electronic equipment determines that the images are matched, the electronic equipment outputs a corresponding rear camera control command.
In the second mode, if the focal length corresponding to the second information representation first preview interface accords with the preset focal length, the front camera is started.
Here, the second information may be understood as information related to an imaging parameter of the first preview interface, such as a focal length; of course, at this time, the focal length corresponding to the first preview interface may be displayed in the first preview interface as one of the objects displayed in the first preview interface.
In the embodiment of the application, under the condition that the rear camera is turned on by the electronic equipment, an operator of the electronic equipment can shoot a long-distance object and a short-distance object through the rear camera; correspondingly, the focal length corresponding to the distant object is greater than the focal length corresponding to the close object. Here, the preset focal length may be understood as a tele focal length.
In practical application, when the electronic equipment starts the rear camera and an operator of the electronic equipment can shoot a remote object such as a person through the rear camera, the focal length corresponding to the first preview interface is a tele focal length and accords with a preset focal length, and the front camera is triggered to start, so that the operator can be ensured to use first information which accords with the first preset information and is collected by the front camera to trigger the rear camera to collect images under the condition that the holding posture of the electronic equipment is not changed; therefore, the shake of the electronic equipment in the image acquisition process is effectively reduced, the complexity of operation is reduced, and the imaging effect is improved.
And 204, displaying a second preview interface corresponding to the rear camera on a display screen of the electronic equipment.
And the second preview interface comprises a second control for triggering the rear camera to acquire images.
In the embodiment of the application, when the rear camera is turned on, and before and after the front camera is turned on, the viewing interface of the rear camera is the same, that is, the viewing angle of the rear camera is not changed, then, the second preview interface and the first preview interface are the same interface, and the first preview interface also includes the second control.
In some embodiments of the present application, when the rear camera is turned on, and before and after the front camera is turned on, the viewing interface of the rear camera is different, that is, the viewing angle of the rear camera is changed, then, the second preview interface is different from the first preview interface, and at this time, the first preview interface may still include the second control.
It should be noted that the electronic device in the embodiment of the present application may support more than two paths of data processing, and therefore, the electronic device may also turn on the front camera under the condition that the rear camera is turned on; however, in the embodiment of the present application, under the condition that the front camera and the rear camera are simultaneously turned on, only the second preview interface corresponding to the rear camera may be displayed on the display screen of the electronic device, that is, the preview interface corresponding to the front camera is not displayed on the display screen, so that power consumption of the electronic device may be saved.
And step 206, if the first information accords with the first preset information, controlling the rear camera to acquire the image.
In some embodiments of the present application, in a scenario where the electronic device controls the rear camera to perform image acquisition through the first information associated with the action of the operator in the image acquired by the front camera, the control of the rear camera may be further implemented through the following steps,
and step 207, acquiring touch operation aiming at the second control, and controlling the rear camera to acquire images.
That is to say, when the rear camera of the electronic device is in an open state and the front camera of the electronic device is opened, the electronic device can control the rear camera based on information associated with the action of the operator in the image collected by the front camera in real time and can also control the rear camera based on the touch operation of the operator on the second control in the process of controlling the rear camera to collect the image through the first information; that is to say, in the image acquired by the electronic device using the front-facing camera, in the scene where the first information associated with the action of the operator controls the rear-facing camera to acquire the image, each control in the second preview interface corresponding to the rear-facing camera is in an activated state, and still can be used to trigger the rear-facing camera to execute the function of each control. It should be noted that, if the electronic device detects the first information conforming to the first preset information and the touch operation for the second control at the same time, the electronic device responds to the touch operation and controls the rear camera to perform image acquisition, so that the rear camera is accurately controlled.
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.
Based on the foregoing embodiments, an embodiment of the present application provides an image capturing method, which is applied to an electronic device having a front camera and a rear camera, and as shown in fig. 3, the method includes the following steps:
The first feature information comprises gesture action feature information and/or facial action feature information.
In the embodiment of the application, the first information may include information associated with the action of the operator in one image acquired by the front camera at the current time; that is, in one implementation, the electronic device may control the rear camera to perform image capturing based on information in one image captured by the front camera at a certain time.
In the embodiment of the application, the electronic equipment can flexibly select the first characteristic information under different image acquisition scenes.
For example, in an image capturing scenario, as shown in fig. 4 and 5, if an operator of the electronic device, that is, a photographer holds the electronic device with both hands, for example, a camera to capture a scene, the first feature information includes expression feature information, such as a smiling expression 41 in fig. 4 and a blinking expression 51 in fig. 5, at this time, the photographer does not need to make fingers to shoot or record a video, so that the shooting posture can be maintained more stably, a better imaging effect can be achieved, and the effect is particularly obvious in a high-power zoom situation, that is, in a long-focus scene.
For example, in another image capturing scenario, if an operator of the electronic device holds the electronic device with one hand, it is not convenient to click a second control, such as a photographing key or a video recording key, in a second preview interface on the display screen, and the first feature information includes expression feature information and/or gesture feature information, so that it is avoided that a hand not holding the electronic device is moved by a large margin to click the display screen, which results in a decrease in imaging quality, and meanwhile, accurate control of the rear camera is achieved.
For example, in another image capturing scenario, if an operator of the electronic device uses a stand, that is, the operator is a certain distance away from the electronic device, the first feature information includes expression feature information and/or gesture feature information, so that the operator can control the rear camera to capture an image through the first feature information in the image captured by the front camera without touching the electronic device, thereby effectively freeing both hands, ensuring stability of the photographing device, and improving imaging effect.
It should be noted that, in the process of image acquisition by an operator holding the electronic device, by the image acquisition method provided by the embodiment of the present application, the rear camera is triggered to perform image acquisition based on the micro-expression acquired by the front camera, and the operation of capturing in the zoom state can be realized, so that the shake of photographing in the zoom process is reduced.
In some embodiments of the application, the first image may further include a plurality of sub-images corresponding to a plurality of moments acquired by a front-facing camera in the target time period, and the step 302 of acquiring the first feature information in the first information may be implemented by: and acquiring each second characteristic information in each sub-image in the plurality of sub-images to obtain a plurality of second characteristic information.
The second feature information comprises gesture feature information and/or expression feature information. The first characteristic information includes a plurality of second characteristic information.
Here, the first image may further include a plurality of sub-images acquired by the front camera in the target time period and corresponding to different times in the plurality of times, that is, the first image may be understood as an image set including a plurality of frames of sub-images. That is, in another implementation manner, the electronic device may control the rear camera to perform image acquisition based on a plurality of sub-images acquired by the front camera at a plurality of times.
In the embodiment of the present application, the plurality of sub-images may be a plurality of multi-frame sub-images at different time instants extracted from a video captured in a target time period.
And 303, controlling the rear camera to acquire an image if the first characteristic information accords with preset characteristic information.
In this embodiment of the application, in step 303, if the first feature information matches the preset feature information, the rear camera is controlled to perform image acquisition, which may be implemented by the following steps: and if a preset number of second characteristic information in the plurality of second characteristic information accords with the preset characteristic information, determining that the first characteristic information accords with the preset characteristic information, and controlling the rear camera to acquire images.
Here, the preset number may be less than or equal to a total number of the plurality of second characteristic information.
The electronic equipment compares the plurality of second feature information with preset feature information under the condition that the plurality of second feature information are obtained, and if a preset number of second feature information in the plurality of second feature information are determined to accord with the preset feature information, the first feature information is determined to accord with the preset feature information, so that the rear camera is controlled to collect images; therefore, the triggering of the shooting function of the rear camera by the misoperation of an operator of the electronic equipment is avoided, the misjudgment of the electronic equipment is reduced, and the accuracy of image acquisition of the electronic equipment by controlling the rear camera through the information in the image acquired by the front camera is improved.
In the embodiment of the application, if the preset number is smaller than the total number of the plurality of second feature information, in the process of comparing the plurality of second feature information with the preset feature information when the electronic device acquires the plurality of second feature information, once the preset number of second feature information accords with the preset feature information, the judgment of the second feature information which is not compared with the preset feature information in the plurality of second feature information is stopped, so that the first feature information accords with the preset feature information, and the rear camera is controlled to perform image acquisition; thus, the processing efficiency of the electronic equipment is improved.
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.
Based on the foregoing embodiment, taking the micro expression, which is facial motion feature information acquired by a front camera of an electronic device, as an example to control a rear camera of the electronic device to perform image acquisition, an image acquisition method provided in an embodiment of the present application is further described, with reference to fig. 6, the method includes the following steps:
And step 603, the electronic equipment runs the front camera.
Here, when the electronic device turns on the rear camera, if the micro-expression auxiliary photographing function is selected, the electronic device synchronously turns on the rear camera, that is, the front camera is operated. Further, the electronic equipment acquires an image including the micro expression of the operator through the front camera.
And step 604, the electronic equipment displays a second preview interface corresponding to the rear camera on the display screen.
And step 605, performing expression matching on the micro expression in the image acquired by the front camera and the preset expression characteristic by the electronic equipment under the condition that the micro expression assisted shooting is started.
In the scene, when an operator touches a second control in a second preview interface, the rear camera responds to the touch operation, and normally framing and photographing are carried out; of course, in this state, when the micro expression in the image acquired by the front camera matches the preset expression feature, the rear camera may also perform the image acquisition operation.
In the embodiment of the application, the electronic equipment can support more than two paths of data processing, so that the electronic equipment can start the front camera under the condition of starting the rear camera; however, in the embodiment of the present application, under the condition that the front camera and the rear camera are simultaneously turned on, only the second preview interface corresponding to the rear camera may be displayed on the display screen of the electronic device, that is, the preview interface corresponding to the front camera is not displayed on the display screen, so that power consumption of the electronic device may be saved. Meanwhile, the auxiliary shooting function and the normal shooting function of the electronic equipment can be overlapped in state, namely the auxiliary shooting does not influence the control of the rear camera by utilizing the second preview interface.
