The image capturing method provided by the embodiment of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.
Referring to fig. 1, a flowchart illustrating steps of an image capturing method according to an embodiment of the present application is shown.
The image shooting method of the embodiment of the application comprises the following steps:
step 101: a first input of image capturing parameters by a user is received.
The first input is a relevant setting operation for image capturing parameters. The image capturing parameters may include, but are not limited to: and enlarging the area. Further, the image capturing parameters may further include: magnification factor, number of continuous shots, etc.
After a camera is opened to display a shooting preview interface, an image shooting parameter setting list can be triggered and displayed in the shooting preview interface through preset operation, and image shooting parameters such as an amplification factor, the number of continuous shooting sheets and the like are set in the setting list.
The zooming-in area is an area to be adjusted in the shooting preview interface, and the target parameters in the zooming-in area in the subsequent shot images are zoomed in by the set zooming factor times. For example: the magnification factor is 3, the target parameter in the magnified area in the captured image is magnified by 3 times. The enlargement area can be defined in the shooting preview interface by the user, and can also be dynamically determined according to the pressing force of the user on the pressing operation executed at a certain position in the shooting preview interface. If the user does not perform the setting operation regarding the enlargement area, the entire shooting preview interface is set as the enlargement area by default. The enlargement area may be provided as one or more. If the user does not set the image shooting parameters such as the amplification factor, the continuous shooting number and the like, the target parameters in the amplification area can be amplified by adopting the default amplification factor of the system, and continuous shooting can be carried out by adopting the default continuous shooting number of the system.
The enlargement area is specified based on a first input from a user, and if other image capturing parameters such as an enlargement factor and the number of continuous shots are set in the first input, the enlargement area is specified and the enlargement factor and the number of continuous shots are specified.
The enlarged region can be a part of the face region of a person to be shot in the person preview interface, and correspondingly, an object in the enlarged region is the face region in the enlarged region; for example: the enlargement area may be a face and mouth area in the shooting preview interface, accordingly, an object in the enlargement area is a mouth, and the target parameter may be a mouth angle raising angle. The zoom-in area may also be a partial area in a preview interface for photographing other non-static objects, for example: the enlargement area may be an area corresponding to a puppy tail in a shooting preview interface including the puppy, an object in the enlargement area may be the puppy tail, and accordingly, the target parameter may be an arc of the puppy tail.
Step 102: a second input by the user is received.
In a specific implementation process, the image capturing device may automatically perform image capturing after determining the image capturing parameters in response to the first input, and may further perform a second input by the user to manually trigger image capturing. When the user manually triggers the image shooting, the image shooting device can be triggered to shoot the first image by executing the second input on the first control.
The first control may be an entity key for triggering image shooting, or may be a virtual key preset in the shooting preview interface for triggering image shooting. The second input may be a long press operation or a single click operation on the first control, etc. And the user manually executes second input to the first control to trigger the image shooting device to shoot the image, so that the controllability of image shooting can be improved.
Step 103: in response to a second input, a first image is captured.
The first image is the first frame image shot in the continuous shooting process.
Step 104: and shooting a second image under the condition that the difference between the target parameters of the objects in the enlarged area in the shooting preview interface and the first image is larger than a first threshold value.
The corresponding amplifiable parameters are different when the types of the shot objects are different, the corresponding amplifiable parameters of the objects of different types are preset in the system, and the amplifiable parameters of the objects in the amplification area are target parameters.
Taking the shot object as the portrait of the person as an example, the enlargeable parameters are expression-related parameters such as: mouth angle lift angle, eyebrow curvature, eye opening angle, etc. And if the amplification area is the area corresponding to the mouth of the shooting object, the target parameter is the mouth angle raising angle.
And under the condition that the object in the enlarged region is a whole or partial face, the target parameters are used for representing the micro expression of the face. Therefore, the micro expression of the person can be continuously shot by the image shooting method provided by the embodiment of the application.
In the case where the object within the magnified region is an object, the target parameters are used to characterize the dynamic changes of the object. Therefore, the image shooting method provided by the embodiment of the application can be used for continuously shooting the micro-changes of the dynamically changing objects.
The image shooting method provided in the embodiment of the application is to shoot details in one or more specific amplification areas in an image after carrying out exaggeration processing. The image shooting method can be applied to shooting scenes of single images, continuous shooting scenes, macro shooting scenes, dynamic photo slow-lens shooting scenes and the like.
Taking the application to a continuous shooting scene as an example, after a plurality of images are continuously shot by the image shooting method provided in the embodiment of the application, the target parameters of the objects in the amplification areas in the shot images are all amplified, so that the characteristics of the objects in the amplification areas in the images are more obvious, and the difference of the images obtained by continuous shooting is conveniently compared and analyzed.
The image shooting method provided by the embodiment of the application receives first input of an image shooting parameter from a user, and determines the image shooting parameter; capturing a first image in response to a second input by the user; and shooting a second image under the condition that the difference of the target parameters of the objects in the enlarged area in the first image in the shooting preview interface is larger than a first threshold value. By amplifying the target parameters of the objects in the amplification area in the shooting preview interface, the characteristics of the objects in the amplification area in the image can be more obvious, and the difference can be highlighted when a plurality of images are compared.
In an alternative embodiment, the step of receiving a first input of image capturing parameters by a user comprises the sub-steps of:
the method comprises the following steps that firstly, first setting operation of a user on an amplification factor and the number of continuous shooting is received;
in this alternative embodiment, the description will be given by taking the example of continuously shooting the images of the persons and recognizing and amplifying the differences in the areas by the micro expression. As shown in the schematic diagram of the image capturing parameter setting interface shown in fig. 2, a user may trigger the system to display an image parameter setting interface in the capturing preview interface, where the image parameter setting interface includes: the user can adjust the continuous shooting number and the expression amplification factor by sliding the corresponding adjusting control.
Fig. 2 shows an image capturing parameter setting interface only by way of example, and in a specific implementation process, the image capturing parameter setting interface is not limited to adjusting the number of continuous shots and the expression magnification factor by sliding the adjustment control, and a target value may also be directly input.
And a second step of receiving the selection operation of the user on the enlarged area in the shooting preview interface.
The selection operation may be a pressing operation on the shooting preview interface, an operation of manually defining an enlarged region in the shooting preview interface, or an operation of defining an enlarged region in the shooting preview interface by using an enlarged region setting frame provided in the system.
In the manner of selecting the enlargement area by performing the pressing operation in the shooting preview interface, the enlargement area may be specifically determined by the pressing position and the pressing time length of the pressing operation, and may also be determined by the pressing position and the pressing force degree of the pressing operation. As shown in the enlarged region selection interface diagram shown in fig. 3, enlarged regions of different sizes may be selected by the user by performing pressing operations for different lengths of time in the photographing preview interface. The area of the magnified region may be proportional to the length of the press as shown in fig. 3. The area of the magnified region may also be inversely related to the length of the compression. The enlarged region may be circular, square or any suitable shape. One or more zooming-in areas can be selected in the shooting preview interface, and the selection flow of each zooming-in area is the same.
When the enlargement area is a circle and the enlargement area is determined according to the pressing operation in the shooting preview interface, the pressing position of the pressing operation is used as the center, the extension radius is determined based on the pressing time length, and the circle area which is formed by taking the center as the circle center and the extension radius as the radius is used as the enlargement area. When the enlargement area is a square and is determined according to the pressing operation in the shooting preview interface, the pressing position of the pressing operation is taken as the center, the length of the extending side is determined based on the pressing time length, and the square area which is formed by taking the center as the center of the square and the length of the extending side as the side length is taken as the enlargement area.
In the optional embodiment, the user can select the enlarged area by performing simple pressing operation in the shooting preview interface, so that the user can operate the area conveniently.
If the enlargement area is selected in the shooting preview interface, the selected enlargement area can be cancelled through the preset operation. The preset operation may be a long-press operation on the selected enlargement area, or a long-press operation on an area other than the selected enlargement area in the shooting preview interface.
In an optional embodiment, in a case that the image capturing parameter includes a magnification factor, after the step of capturing the first image in response to the second input, a magnified area in the capturing preview interface may be further magnified and displayed by the magnification factor.
The enlarged area in the shooting preview interface is displayed after being enlarged, so that the characteristics of the object in the enlarged area can be highlighted, and a user can conveniently find the change of the object in the enlarged area.
It should be noted that, when the image capturing method shown in this embodiment of the present application is used for continuous capturing, except for the first frame of image, that is, the first image, each subsequent image performs image capturing after amplifying the target parameter of the object in the amplified region according to the amplification factor, so that the difference of the object characteristics in the amplified region can be highlighted. After the continuous shooting is finished, a continuous shooting image set can be generated and stored in an album. By enlarging the target parameter of the object in the enlargement area, the adjacent images can show a significant difference although the shooting time interval is short.
In the embodiment of the application, an automatic shooting mechanism is triggered by target parameter detection based on local difference amplification of the shot image. In this optional embodiment, the image capturing parameters further include: a first threshold value; after the step of receiving the first input of the image capturing parameters by the user, the method further comprises the following steps:
adjusting target parameters of the object in the enlarged area in the shooting preview interface according to the first threshold and the enlargement coefficient; and displaying the adjusted shooting preview interface.
Taking the image shooting method provided by the embodiment of the present application as an example, as shown in the schematic diagram of the image shooting parameter setting interface in fig. 4, in the image shooting parameter setting interface, a user needs to set the number of continuous shots, a first threshold and an amplification factor, and when the system detects that the variation of the target parameter of the object in the amplification area in the shooting preview interface exceeds the first threshold set by the user through a preset algorithm, such as a micro expression algorithm, the image shooting is automatically performed.
The user may also adjust the first threshold or the magnification factor after displaying the adjusted shooting preview interface. In the optional embodiment, when the user adjusts the first threshold or the amplification factor in the process of setting the image shooting parameters, the target parameters of the object in the shooting preview interface are adjusted and displayed in the shooting preview picture in real time according to the adjusted image shooting parameters, so that the user can conveniently check the adjustment effect.
Optionally, in a case that a difference between the target parameter of the object in the enlarged area in the shooting preview interface and the target parameter of the object in the enlarged area in the first image is larger than a first threshold, when the second image is shot, detecting a parameter value variation of the target parameter of the object in the enlarged area in the shooting preview interface; and when the parameter value variation is larger than the first threshold value, the amplification area is amplified, and then a second image is shot.
In the process of continuous shooting in the optional mode, the image shooting device automatically detects the change condition of the target parameters of the objects in the enlarged area in the shooting preview interface, and shoots an image every time the change quantity of the target parameters of the objects in the enlarged area exceeds a first threshold value until the number of the continuous shooting images reaches a preset continuous shooting number, or ends the continuous shooting when receiving a shooting stopping instruction. Optionally, the number of the currently shot images is displayed above the screen in the continuous shooting process, so that a user can know the current continuous shooting progress conveniently.
The mechanism for optionally automatically shooting each second image by the image shooting device through detecting the parameter value variation of the target parameter can ensure that the shot images have obvious difference, thereby improving the reserved value of the shot images. The optional image shooting method can be applied to shooting of the head portrait of the person and also can be applied to capturing of moving objects in a plurality of static backgrounds such as meteors, blossoms, birds and the like.
The image shooting method provided by the embodiment of the application receives first input of an image shooting parameter from a user, and determines the image shooting parameter; capturing a first image in response to a second input by the user; and shooting a second image under the condition that the difference of the target parameters of the objects in the enlarged area in the first image in the shooting preview interface is larger than a first threshold value. By amplifying the target parameters of the objects in the amplification area in the shooting preview interface, the characteristics of the objects in the amplification area in the image can be more obvious, and the difference can be highlighted when a plurality of images are compared. In addition, according to the image shooting method provided by the embodiment of the application, the second image shooting mechanism is automatically triggered by detecting the parameter value variation of the target parameter, so that the shot second images can be ensured to have obvious differences, and the reserved value of the shot images is improved.
In the image capturing method provided by the embodiment of the present application, the execution subject may be an image capturing apparatus, and the control module in the image capturing apparatus is used for executing the method for capturing the image.
