The implementations described in the exemplary embodiments below are not intended to represent all implementations consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the present disclosure, as detailed in the appended claims.
According to the technical scheme provided by the embodiment of the disclosure, the shooting parameters of the shooting device can be adjusted according to the layout information of the characteristic images, the intelligent framing and shooting function of the terminal is realized, the intelligence of the terminal is improved, and the user experience is also improved.
Fig. 1 is a flowchart illustrating an image capturing method according to an exemplary embodiment, as shown in fig. 1, including the following steps S101 to S103:
in step S101, layout information of a feature image in a finder lens of a photographing device is acquired.
In the embodiment of the disclosure, image shooting can be performed through a shooting device in the terminal, and in the shooting process, a corresponding view image can be acquired through a view lens of the shooting device, and some images in the view image are characteristic images. Here, the feature image includes: a first face feature image, wherein the first face feature image is located at a boundary of the face image and the background image. For example: when a single person is imaged, the face image is a first face characteristic image; when two or more persons form an image, the face image positioned on the most edge is the first face characteristic image.
Alternatively, the feature image includes: a second subject feature image. For example: when the landscape is imaged, a big tree, a flower, a mountain, an animal, or the like is the subject of imaging, and therefore, the second subject feature image may include: images of trees, flowers, mountains, or animals. The method can be applied to the shooting process with obvious main characteristics.
Thus, acquiring layout information of a feature image in a finder lens of a photographing device includes: and carrying out face recognition on a viewfinder image corresponding to a viewfinder lens of the shooting device to obtain layout information of at least one first face characteristic image, wherein the first face characteristic image is positioned at the boundary of the face image and the background image.
Or, the acquiring layout information of the feature image in the viewfinder lens of the photographing device includes: and carrying out image recognition and edge enhancement processing on a viewfinder image corresponding to the viewfinder lens of the shooting device to obtain layout information of the second main body characteristic image.
In the embodiment of the present disclosure, the layout information includes: size information and position information in the through-view image. For example: if the feature image is a first face feature image, the layout information includes: size information of the face image, and position information of the first face feature image in the through-view image. Or, the feature image is a second main body feature image, specifically a dog image, and then the layout information includes: size information of the dog image, and position information of the dog image in the through-view image.
In step S102, the shooting parameters of the shooting device are adjusted according to the layout information, and the corresponding viewing range is obtained.
In the embodiment of the present disclosure, a corresponding relationship between a preset feature image and a preset adjustment policy may be pre-stored, so that the preset adjustment policy corresponding to the feature image is determined according to the stored corresponding relationship between the preset feature image and the preset adjustment policy; and executing a preset adjusting strategy according to the layout information, and adjusting the shooting parameters of the shooting device.
For example: and aiming at the first face characteristic image, the corresponding preset adjustment strategy is expanded outwards by taking the position corresponding to the position information in the layout information as a starting point, and the expanded distance is five times of the width of the face corresponding to the size information in the layout information. Thus, after the preset adjustment strategy is determined, the preset adjustment strategy is executed according to the layout information, the shooting parameters of the shooting device are adjusted, and the corresponding view range is obtained.
Alternatively, for the second subject feature image, for example: and the preset adjustment strategy corresponding to the tree characteristic image is expanded outwards by taking the position corresponding to the position information in the layout information as a starting point, and the expanded distance is 3 times of the width of the tree corresponding to the size information in the layout information. Or, the preset adjustment strategy corresponding to the mountain stone characteristic image is expanded outwards by taking the position corresponding to the position information in the layout information as a starting point, and the expanded distance is 1.5 times of the width of the tree corresponding to the size information in the layout information. Thus, after the preset adjustment strategy is determined, the preset adjustment strategy is executed according to the layout information, the shooting parameters of the shooting device are adjusted, and the corresponding view range is obtained.
Therefore, the corresponding shooting parameters are adjusted according to the preset adjustment strategy, so that the method is relatively quick and the intelligent framing and shooting speed is increased.
Of course, the function of intelligent framing and shooting may be only for imaging a person, and the position corresponding to the position information in the layout information may be directly used as a starting point to be expanded outward, where the expanded distance is n times of the width of the face corresponding to the size information in the layout information, and n may be determined according to the application scene. 5. 6, or 7, etc. Thus, the viewing range determines that the shooting parameters of the corresponding shooting device can be adjusted, for example: the focal length, zoom factor, etc. may be determined. That is, after the shooting parameters of the shooting device are adjusted, the obtained viewing range matches the viewing range determined from the layout information.
In the above embodiments, the preset adjustment policy includes width adjustment, and may further include height adjustment, for example: the preset adjustment strategy is to take the position corresponding to the position information in the layout information as a starting point and expand the position outwards, and the expanded distance is 3 times of the width of the feature image corresponding to the size information in the layout information, 1.5 times of the height of the feature image, and the like, and the specific steps are not listed in a row.
In step S103, the imaging device is controlled to capture an image within the finder range.
After the corresponding viewing range is obtained, the shooting device can be controlled to shoot the image in the viewing range. For example, the shooting device is triggered, and the shooting device shoots according to the adjusted shooting parameters, so that an image in the framing range is obtained.
Therefore, the shooting parameters of the shooting device can be adjusted according to the layout information of the characteristic images, the intelligent framing and shooting function of the terminal is achieved, the intelligence of the terminal is improved, and the user experience is also improved.
In another embodiment of the present disclosure, an application scenario may be defined in one step, that is, only when the intelligent framing shooting function is turned on, the shooting parameters of the shooting device are adjusted according to the layout information of the feature image, so that the intelligent framing shooting function of the terminal is realized. Therefore, before acquiring the layout information of the feature image in the viewfinder lens of the shooting device, the method further comprises the following steps: and when the intelligent framing shooting function is determined to be started, acquiring the layout information of the characteristic images in the framing lens of the shooting device.
And it is determined that the opening process of the intelligent framing shooting function can be various, for example: through the intelligent shooting function switch that finds a view of predetermineeing, include: detecting the state of a preset intelligent framing and shooting function switch; and when the intelligent framing and shooting function switch is in an on state, the intelligent framing and shooting function is determined to be on. The embodiment determines the state of the intelligent framing and shooting function by setting the intelligent framing and shooting function switch, and is simple and easy to implement.
Of course, in another embodiment of the present disclosure, when it is determined that the smart view shooting function is turned off, the shooting device is controlled to perform image shooting. Therefore, when the intelligent framing shooting function is not available, the shooting parameters of the shooting device can be directly shot without being adjusted, the terminal shooting function is ensured, and the stability of terminal application is improved.

In step S202, it is determined whether the smart view shooting function switch is in an on state? If yes, go to step S203, otherwise go to step 207.
In step S203, face recognition is performed on a through image corresponding to a through lens of the photographing device, and layout information of at least one first face feature image is obtained.
For example: when a single person is imaged, only the layout information of one first face characteristic image needs to be acquired.
When two or more persons are imaged, the layout information of the leftmost one of the first face feature images and the layout information of the rightmost one of the first face feature images are acquired.
FIG. 3 is a diagram illustrating a viewfinder image according to an exemplary embodiment. As shown in fig. 3, the wire frame is a first face feature image, and the layout information of the first face feature image is acquired.
In step S204, a first preset adjustment policy corresponding to the first facial feature image is determined according to the stored correspondence between the preset feature image and the preset adjustment policy.
For example: the first preset adjustment strategy includes: and taking the position corresponding to the position information in the layout information as a starting point, and expanding outwards, wherein the expanded distance is 5 times of the width of the first face characteristic image corresponding to the size information in the layout information, and the height of the first face characteristic image is 1.5 times.
In step S205, according to the layout information, a first preset adjustment strategy is executed to adjust the shooting parameters of the shooting device, and a corresponding view range is obtained.
In step S206, the imaging device is controlled to capture an image within the finder range. The flow ends.
The focus of the shooting device, the zoom factor and other shooting parameters are adjusted, so that the shooting device is triggered to shoot images.
