Detailed Description

The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.

Referring to fig. 1, there is shown a flowchart of a photographing method according to an embodiment of the present invention, the photographing method being applied to a mobile terminal, including:

step 101: and acquiring a preview image displayed on a shooting preview interface in a shooting preview mode.

In this step, the mobile terminal may enter a shooting preview mode from an application program such as a camera, so that, in the shooting preview mode, the relevant data is acquired for the preview image displayed in the shooting preview interface.

Step 102: and performing gesture detection on the preview image.

In this step, after a preview image displayed on the shooting preview interface is acquired, whether a gesture exists in the preview image is detected. The gesture required to be detected can be a gesture with preset characteristics, and the gesture with the preset characteristics can be preset by a user or can be preset automatically by the mobile terminal. Different image processing modes can enable the image to present different effects, and the image processing technology in the same form can process the image to different degrees so as to achieve different effects, wherein the gesture with preset characteristics can be set according to different processing effects, for example: the algorithm level of an image processing technique comprises five levels, and the different levels correspond to different processing degrees, so that each level can be represented by a gesture respectively.

In this step, an image recognition algorithm may be employed to detect a gesture in the preview image.

Step 103: and if the gesture with the preset characteristics is detected, determining the image processing parameters according to the detected gesture.

In this step, an image processing parameter corresponding to the gesture may be determined according to the detected gesture. For example, an algorithm level corresponding to the gesture may be determined according to the detected gesture, so as to obtain a data parameter in the algorithm level, and the obtained data parameter may be determined as the image processing parameter.

In this step, a pattern matching algorithm may be employed to identify the image processing parameters represented by the detected gesture.

Step 104: and processing the image according to the image processing parameters.

In the shooting preview mode, the image is processed based on the determined image processing parameters, and the processed image is used for previewing or shooting.

In this embodiment, the mobile terminal may acquire the preview image displayed in the shooting preview interface in the shooting preview mode, so that whether the preview image has a gesture with preset features may be determined in the acquired preview image, once the gesture is detected, the image processing parameter corresponding to the gesture may be determined according to the detected gesture, and the mobile terminal performs image processing according to the image processing parameter. Therefore, when the photographer gestures in the shooting preview interface according to the expected image processing effect, the mobile terminal can recognize the gestures, and sets the image processing parameters according to the gestures to complete the corresponding image processing. Therefore, the shot person can control the image processing mode through gestures, the shot person does not need to operate on the mobile terminal, the operation is convenient and fast, and different image processing effects can meet the requirements of different shot objects.

On the basis of fig. 1, fig. 2 shows a flowchart of a shooting method according to another embodiment of the present invention, in which the image processing parameters include blurring parameters, and step 103 includes:

step 1031: and if the gesture with the preset characteristics is detected, detecting a shooting object in the preview image.

In this step, after the gesture of the preset feature is detected, the photographic subject in the preview image is first detected, so as to determine the blurring region according to the photographic subject.

Step 1032: based on the detected photographic subject, a background area where the photographic subject is located is identified.

In this step, in order to further determine the blurring region, a background region where the photographic subject is located may be identified from the photographic subject, thereby regarding the background region as the blurring region.

Step 1033: based on the detected gesture, blurring parameters corresponding to the gesture are identified.

After the blurring area is determined, based on the detected gesture, blurring parameters represented by the gesture are recognized, and the blurring parameters are obtained.

Step 1034: based on the identified blurring parameter, an aperture parameter is set.

And setting the aperture parameters of the current blurring treatment according to the acquired blurring parameters.

In this embodiment, step 104 includes:

step 1041: blurring a background area where the object is located according to the aperture parameter.

After the setting of the aperture parameters is finished, blurring processing is directly carried out on the determined background area.

In this embodiment, the image processing technique may include blurring. Referring to table 1, when performing the blurring process, the aperture range that can be adjusted by the blurring process is f/1 to f/16, and preferably, the blurring process can be set to several levels according to different effects that can be achieved by different aperture values, and each level corresponds to a blurring algorithm. For example: assuming that f/1, f/2, f/4, f/8 and f/16 groups of aperture values are adjusted, blurring effects are obviously different, algorithms corresponding to the f/1, f/2, f/4, f/8 and f/16 groups of aperture values can be defined as different algorithm levels, each level of algorithm is represented by one gesture, a gesture "1" represents one level, an aperture value is f/1, a gesture "2" represents two levels, an aperture value is f/2, a gesture "3" represents three levels, an aperture value is f/4, a gesture "4" represents four levels, an aperture value is f/8, a gesture "5" represents five levels, and an aperture value is f/16.

Gesture	Aperture parameter
		Gesture "1"	f/1
Gesture "2"	f/2
		Gesture "3"	f/4
Gesture "4"	f/8
		Gesture "5"	f/16

TABLE 1

Referring to table 1, if the gesture in table 1 is detected, the blurring parameter corresponding to the gesture is identified according to the gesture, which can be understood as: and identifying the algorithm grade of the blurring according to the gesture, so as to obtain the blurring parameter according to the algorithm grade. Further, setting the aperture parameters in the blurring parameters into the blurring algorithm, and performing blurring processing on the preview image again by the algorithm according to the set aperture parameters.

For the blurring process, it is referred to that, when one subject is present, a background region of the subject may be blurred, and when a plurality of subjects are present, a common background region of the plurality of subjects may be blurred.

On the basis of fig. 2, fig. 3 shows a flowchart of a photographing method according to another embodiment of the present invention, in which step 1033 includes:

step 10331: based on the detected gestures, a number of detected gestures is determined.

In this step, if there is more than one detected gesture, statistics on the detected gestures are required to determine the blurring parameters according to the calculation result.

Step 10332: and if the number of the detected gestures is one, identifying blurring parameters corresponding to the gestures.

And when the number of the gestures is one, directly identifying blurring parameters corresponding to the gestures, and using the blurring parameters as a basis for setting aperture parameters to blur the background areas of one or more shooting objects according to the aperture parameters.

Step 10333: and if the number of the detected gestures is two, identifying the sum of blurring parameters corresponding to the two gestures respectively.

When the number of the gestures is two, the sum of the blurring parameters corresponding to the two gestures may be calculated after the blurring parameters corresponding to the two gestures are sequentially recognized. For example, after two gestures are recognized, the two gestures respectively represent different blurring levels, the sum of the two blurring levels can be calculated first, and then blurring parameters of the blurring levels are obtained according to the calculated blurring levels, so that the blurring parameters serve as bases for setting aperture parameters, and background areas of two or more photographic objects are blurred according to the aperture parameters.

Such as: the method comprises the steps of detecting two shooting objects, namely a shooting object A and a shooting object B respectively, detecting that the gesture of the shooting object A is a gesture '1', the gesture of the shooting object B is a gesture '2', identifying that the blurring levels respectively represented by the two gestures are a first level and a second level, adding the identified results, namely the total blurring level is a third level, so as to obtain blurring parameters of the third-level blurring level, setting the aperture value in the corresponding aperture parameter to be f/4, and blurring the common background area of the two shooting objects to the utmost.

Step 10334: and if the number of the detected gestures is more than two, identifying the average value of the blurring parameters corresponding to the plurality of gestures respectively.

When the number of the gestures is greater than two, the average value of the blurring parameters corresponding to the gestures can be calculated after the blurring parameters corresponding to the gestures are recognized. For example, after more than two gestures are sequentially recognized, the gestures respectively represent different blurring levels, an average value of the blurring levels can be calculated first, and then blurring parameters of the blurring levels are obtained according to the calculated blurring levels, so that the blurring parameters serve as bases for setting aperture parameters, and a common background area of more than two photographic objects is blurred according to the aperture parameters.

Therefore, in the embodiment, the purpose of controlling or adjusting the image processing is achieved by detecting the number of the gestures and by a certain algorithm.

It should be noted that, in the embodiment of the present invention, it is assumed that only one gesture can be recognized at most for one photographic subject, so that when two gestures are recognized, at least two photographic subjects are described, and so on.

On the basis of fig. 1, fig. 4 shows a flowchart of a shooting method according to another embodiment of the present invention, in which the detected gesture is one, the image processing parameters include a beauty parameter, and step 103 includes:

In this step, a photographic subject is first detected to determine a beauty target from the detected photographic subject.

Step 1035: and determining a shooting object corresponding to the gesture according to the detected gesture.

And according to the detected gesture, taking the shooting object corresponding to the gesture as a beautifying object.

Step 1036: and identifying the beauty parameters corresponding to the gestures based on the detected gestures, and setting the beauty parameters.

And after the beauty object is determined, recognizing the beauty parameters corresponding to the gestures, and setting the current beauty parameters according to the beauty parameters.

Step 104 comprises:

step 1042: and performing beauty treatment on the shooting object corresponding to the gesture according to the beauty parameters.

In the present embodiment, the image processing technique may include a beauty process. Similar to blurring treatment, according to different effects of the beauty treatment, the beauty treatment can be divided into several different grades, the different grades are respectively represented by different gestures, the beauty treatment of the different grades corresponds to different algorithms, and each algorithm corresponds to different beauty treatment parameters. And after the corresponding beauty grade is identified according to the gesture, acquiring the beauty parameter corresponding to the grade, thereby completing the conversion from the gesture to the data, further setting the beauty parameter of the current image processing through the beauty parameter, setting the beauty processing into an algorithm, and completing the beauty processing of the shooting object through calculation.

In this embodiment, a gesture is taken for a user, and the user can actively make the gesture according to the needs of the user to achieve the purpose of beautifying. When there are more photographed persons and at least two photographed persons have a demand for beauty, at least two photographed persons can make gestures. In the next embodiment, this case is explained in detail.

On the basis of fig. 1, fig. 5 shows a flowchart of a photographing method according to another embodiment of the present invention, in which at least two gestures are detected, the image processing parameters include a beauty parameter, and step 103 includes:

Step 1037: and determining the shooting object corresponding to each gesture according to the detected gestures.

Step 1038: and identifying the beauty parameters corresponding to each gesture respectively based on the detected gestures.

Step 104 comprises:

step 1043: and according to each group of beauty parameters, respectively carrying out beauty treatment on the shooting object corresponding to each gesture.

In this embodiment, different from the previous embodiment, different gestures may be made for different persons to be photographed according to personal needs, and when a plurality of gestures are detected, the beauty parameter represented by each gesture may be sequentially recognized, so that corresponding beauty parameters are set for different photographing objects, and each group of beauty parameters is respectively set into different algorithms to perform beauty processing for different photographing objects. Preferably, the face-beautifying processing can be sequentially performed on the shooting objects in sequence, in this case, the mobile terminal only corresponds to one face-beautifying algorithm at one time point; it is also possible to perform different algorithms simultaneously on different subjects.

Illustratively, in step 101, the camera may be controlled to capture each frame of preview image to obtain a preview image, and each captured frame of preview image is stored in the buffer, so that in step 102, gesture detection may be performed in the buffered preview image, and these steps may be performed in real time and synchronously to ensure that detection of any gesture is not missed.

In summary, the shooting method of the embodiment of the present invention brings convenience to the user, for example: when the selfie stick is used, if the mobile terminal is far away from a shot person, and the shot person needs to adjust an image processing mode, the image processing mode can be realized only through gestures and is not limited by distance; for another example: when the photographer controls the mobile terminal by one hand, the other hand does not need to carefully adjust the image processing mode and can realize the operation only through simple gestures; for another example: compared with the technology of adjusting the image processing mode through the language, the gesture is used for adjusting, the problem that the recognition difficulty is large due to different languages, different accents and the like can be solved, and the universality is higher.

It should be noted that the embodiments of the present invention are not limited to the blurring process and the beautifying process, and the methods provided in the embodiments of the present invention can be applied to various image processing techniques.
