step 101, starting a first camera and a second camera;

in the embodiment of the present invention, the mobile terminal may include an intelligent device with at least two cameras, and the mobile terminal is adopted to perform shooting, and first receives a camera opening request of a user, where a camera opening request triggered by the user may be a click event of touching a screen, a press event of pressing a physical key, or other ways to open the camera.

Further, after the mobile terminal receives a camera opening request of a user, the first camera and the second camera are opened according to the request, it should be noted that the order of opening the cameras may be simultaneously opened or sequentially opened according to a certain order, and the embodiment of the present invention does not limit this.

102, acquiring depth of field information of a shot object in a view frame;

after the first camera and the second camera are started, when a user adjusts shooting parameters aiming at the second camera, the mobile terminal obtains depth-of-field information of a shot object in the view frame; that is, the user has completed focusing operation, photometric operation, and focus adjusting operation, etc. on the object to be photographed, wherein the photographing parameters may include focus information and/or aperture information and/or shutter time information and/or gain information; specifically, the focal length information refers to the distance from the center of a lens to an imaging plane of a CCD (Charge-coupled Device) in a camera of the mobile terminal, and the focal length information can be set according to the limit of the focal length information of the mobile terminal, and the aperture is a Device for controlling the amount of light entering the CCD through a lens of the camera, which is usually inside the lens. The size of the aperture information is generally expressed by F value, and the larger the F value, the smaller the amount of light entering. A shutter is a device in a camera apparatus for controlling the time during which light irradiates a CCD. The shutter time information may be the time of illumination of the CCD, e.g., 1/250 seconds, 1/60 seconds, which determines the brightness of the photograph. The gain information refers to a process parameter for compensating the image. It should be noted that, in the embodiment of the present invention, the first camera may be configured to capture an image, and the second camera may be configured to receive the capture parameters to further determine depth of field information, where the functions of the two cameras are different, where the depth of field information may refer to a distance range between the front and the back of the object to be captured, which is measured by an imaging device capable of obtaining a clear image at the front edge of a lens or other type of imager (such as a professional capture camera) of the mobile terminal. In the embodiment of the present invention, the second camera may be configured to determine depth information, that is, a distance at which a clear image can be obtained for identifying the object to be shot. It should be noted that the above-mentioned examples of the shooting parameters are only enumeration in the embodiment of the present invention, and the shooting parameters may also include shooting parameters such as white balance information, which is not limited in the embodiment of the present invention.

103, judging whether the movement information of the shot subject is smaller than a preset amplitude threshold value;

in practical application to the embodiment of the invention, the mobile terminal adopts the first camera to collect the first characteristic image and the second characteristic image at a specific time interval; the first characteristic image comprises first position information of the shot main body, the second characteristic image comprises second position information of the shot main body, whether the first position information is consistent with the second position information is further judged, when the first position information is inconsistent with the second position information, the difference value of the first position information and the second position information is determined to be movement information, and whether the movement information is smaller than a preset amplitude threshold value is judged. The method comprises the steps of acquiring position information of a shot subject at different moments by adopting a first camera, specifically, the first camera can shoot two images containing the shot subject at different moments, identifying the shot subject through an image identification technology, further acquiring position information of the shot subject in the two images, judging whether the position information is changed, calculating the change amplitude of the position information of the two images, and determining depth-of-field information again according to shooting parameters of a user when the change amplitude (namely, movement information) of the position information is larger than a preset amplitude threshold value and the shot subject is considered to move. It should be noted that setting the preset amplitude threshold can prevent the shaking of the user from affecting the effect of the photo; further, the first camera is set by adopting shooting parameters of a second camera.

Step 104, when the movement information is smaller than a preset amplitude threshold value, closing the second camera;

specifically, when the movement information is detected and is smaller than a preset amplitude threshold value, it can be considered that the subject to be photographed does not occur or the shake of the moving user is not enough to affect the depth information of the image, the second camera is automatically turned off.

And 105, shooting an image by using the first camera.

Specifically, in the embodiment of the invention, after the second camera is automatically closed, a click event aiming at a screen button of a user is received; for the click event, the first camera captures an image, it should be noted that the manner in which the user captures the image may include a click event by touching a screen, a pressing event by pressing a physical key, or a manner in which an automatic timing capture is set, which is not limited in this embodiment of the present invention.

In the embodiment of the invention, the first camera and the second camera are started; acquiring the depth of field information of a shot object in a view frame; judging whether the movement information of the shot subject is smaller than a preset amplitude threshold value or not; when the movement information is smaller than a preset amplitude threshold value, closing the second camera; and shooting an image by adopting the first camera. In the embodiment of the invention, the second camera is adjusted by adopting a plurality of shooting parameters, so that the depth of field information is effectively determined, the preset amplitude threshold value is further set, whether the shot main body moves or not is accurately judged, meanwhile, the shooting effect is prevented from being influenced by the shaking of a user under certain conditions, the shooting effect and the quality of pictures are improved, and the user experience is enhanced; and finally, after determining that the depth of field information or the object does not move, closing the second camera, and shooting by adopting the first camera, so that the power consumption is reduced, and the energy is saved.

Method embodiment two

Referring to fig. 2, a flowchart illustrating steps of a second embodiment of a method for shooting with a mobile terminal according to an embodiment of the present invention is shown, where the method specifically includes the following steps:

step 201, starting a first camera and a second camera;

the mobile terminal is adopted to shoot, a camera opening request of a user is received, the camera opening request triggered by the user can be started through a click event of contacting a screen, a pressing event of pressing an entity key or a preset triggering mode (such as a mode of shaking or specific screen sliding).

Specifically, after the mobile terminal receives a camera opening request of a user, the first camera and the second camera are opened according to the request. It should be noted that, in the embodiment of the present invention, the first camera may be used for shooting, and the second camera may be used for determining depth information.

Step 202, obtaining depth of field information of a shot object in a view frame;

in the embodiment of the invention, after the first camera and the second camera are started, when a user adjusts the shooting parameters aiming at the second camera, the mobile terminal acquires the depth of field information of a shot object in the view frame; that is, the user has completed focusing operation, photometric operation, and focus adjusting operation, etc. on the object to be photographed, wherein the photographing parameters may include focus information and/or aperture information and/or shutter time information and/or gain information; it should be noted that the automatically adjusted shooting parameters for the second camera may include auto focus, auto exposure, and auto white balance. In the embodiment of the present invention, the second camera may be configured to determine depth information, that is, a distance at which a clear image can be obtained for identifying the object to be shot.

Step 203, collecting a first characteristic image and a second characteristic image by using the first camera at a specific time interval; wherein the first feature image includes first position information of the subject, and the second feature image includes second position information of the subject;

specifically, the first camera captures the first characteristic image and the second characteristic image at a specific time interval, where the specific time interval may be 0.1s or 0.5s, and may be any time value set according to an actual situation, and the implementation of the present invention is not limited specifically. The photographed subjects in the first characteristic image and the second characteristic image can be identified and the corresponding first position information and second position information can be recorded in the processor and the memory through image identification without outputting and previewing.

Step 204, judging whether the first position information is consistent with the second position information;

further, comparing first position information with second position information, judging whether the first position information is consistent with the second position information, and when the first position information is consistent with the second position information, indicating that the shot main body does not move or the user does not shake enough to influence the determination of the depth of field information.

Step 205, when the first location information is inconsistent with the second location information, determining that a difference value between the first location information and the second location information is movement information;

specifically, the difference between the first position information and the second position information is determined as the movement information. For example, when the rectangular plane coordinate system is established with the length and width directions of the image captured by the first camera as references, and the first position information of the first feature image is the coordinates (2.32, 1.45), and the second position information of the second feature image is the coordinates (2.32, 1.48), it indicates that the subject has moved 0.03 coordinate points in the width direction, and the difference is 0.03 in the width direction, and the difference is determined as the movement information.

Step 206, judging whether the movement information is smaller than a preset amplitude threshold value;

it should be noted that the preset amplitude threshold may be any value in the width direction and the length direction of a rectangular planar coordinate system established with the length direction of the image captured by the first camera as a reference, for example, the preset amplitude threshold sets 0.3 coordinate points in the width direction or 0.4 coordinate points in the length direction, where the coordinate points may be used as length units, and of course, the preset amplitude threshold may also be any value set according to actual situations, which is not limited in this embodiment of the present invention.

In a preferred embodiment of the present invention, before the step of turning off the second camera when the movement information is smaller than a preset amplitude threshold, the method further includes: and setting the first camera by adopting the shooting parameters of the second camera.

Step 207, when the movement information is smaller than a preset amplitude threshold value, closing the second camera;

when the movement information is detected and is smaller than the preset amplitude threshold value, the second camera is automatically turned off when the photographed main body does not occur or the shake of the mobile user is not enough to influence the depth information of the image.

And step 208, shooting an image by using the first camera.

In a preferred embodiment of the present invention, the step of capturing the image by using the first camera includes: receiving a click event aiming at a screen button of a user; and aiming at the click event, the first camera shoots an image.

In the embodiment of the invention, whether the first position information is consistent with the second position information is judged by adopting a first characteristic image and a second characteristic image which are acquired by the first camera at a specific time interval, when the first position information is inconsistent with the second position information, determining the difference value between the first position information and the second position information as movement information, judging whether the movement information is smaller than a preset amplitude threshold value, when the movement information is smaller than the preset amplitude threshold value, the second camera is closed, the first camera is adopted to shoot the image, whether the moving amplitude of the shot main body exceeds a certain threshold value or not is judged, the change of the depth of field information caused by the shaking of a user or the movement of the shot object is effectively prevented, the quality of the image is improved, the user experience is greatly improved, the power consumption is reduced, and resources are saved.
