As shown in fig. 1, fig. 1 is a flowchart illustrating a method for processing image data according to an exemplary embodiment of the present disclosure, applied to a terminal including: a first lens and a second lens, the method comprising the steps of:

in step 101, preset trigger information is monitored within a display interface of a first image, which is a history image captured by a first lens.

The method for processing image data provided by the embodiment of the disclosure is applied to a terminal, the terminal comprises a first lens and a second lens, and both the first lens and the second lens can be used for image shooting. The first lens and the second lens may be the same type of lens or different types of lenses, for example, the first lens is a non-wide-angle lens, and the second lens is a wide-angle lens; for another example, the first lens and the second lens are both non-wide-angle lenses. In the embodiment of the disclosure, the terminal performs linkage control on the first lens and the second lens, and when the first lens is controlled to shoot images, the second lens is controlled to shoot images according to a preset shooting rule.

The terminal has acquired a first image and a second image when executing this step, wherein the first image is a history image captured by a first lens, the second image is a history image captured by a second lens when the first lens captures the first image, and an association exists between the first image and the second image.

When the terminal displays the first image, preset trigger information is monitored in a display interface of the first image, and if the preset trigger information is monitored, subsequent operation is started.

There are various ways to monitor the preset trigger information. For example, when a preset option is provided on the display interface of the first image, the terminal monitors whether a selection operation for the preset option is received within the display interface of the first image. Illustratively, the terminal opens an album and displays a first image in the album, a preset option is arranged on a display interface of the first image, and at this time, the terminal monitors whether a selection operation for the preset option is received in the display interface. For another example, whether voice information including indication content input by a user is received or not is monitored, and the indication content instructs the terminal to start an image data processing function.

In an optional embodiment, before the terminal monitors the preset trigger information in the display interface of the first image, a first image captured by the first lens and a second image captured by the second lens need to be acquired.

For example, referring to fig. 2 which is a flowchart illustrating another method for processing image data, before the terminal monitors the preset trigger information in the display interface of the first image, the operation of acquiring the first image and the second image before the terminal monitors the preset trigger information in the display interface of the first image may be implemented through the following steps 105 to 108:

in step 105, when the first lens is detected to enter the preset shooting mode, the second lens is turned on.

The preset photographing mode may be various, such as an on mode, a photographing mode, and the like. When the preset shooting mode is the opening mode, after the first lens is detected to be opened, the second lens is opened; when the preset shooting mode is the shooting mode, after the first lens is detected to start shooting the first image, the second lens is started.

In step 106, an initial image of the second shot acquisition is acquired.

And after the terminal opens the second lens, acquiring an initial image acquired by the second lens, wherein the initial image is an image acquired by the second lens in a period after the second lens is opened and before the second image starts to be shot.

In step 107, it is determined whether preset image information is included in the initial image.

The preset image information is in various types, for example, a preset kind of a subject (e.g., a person, an animal, a building, etc.), a specified subject (e.g., a specified person, a specified animal, a specified building, etc.), and the like.

And after the terminal acquires the initial image acquired by the second lens, determining whether the initial image comprises preset image information.

In step 108, if the initial image includes the preset image information, the second lens is controlled to capture a second image.

And after the terminal determines that the initial image currently acquired by the second lens comprises the preset image information, the second lens is controlled to shoot the second image. The terminal acquires the initial image subsequently acquired by the second lens after judging that the initial image currently acquired by the second lens does not include the preset image information, determines whether the initial image subsequently acquired includes the preset image information, and controls the second lens to shoot the second image under the condition that the initial image subsequently acquired is determined to include the preset image information.

In operation, if the first lens finishes shooting the first image, the second lens still does not acquire the initial image including the preset image information, the terminal may automatically close the second lens, or if the terminal monitors that the first lens is not used again within the preset duration to shoot the image, the terminal may automatically close the second lens, or after receiving a preset instruction input by a user, the terminal closes the second lens, the preset instruction has various types, for example, an instruction to close the second lens, an instruction to close the first lens and the second lens at the same time, and the like.

Based on the settings from step 105 to step 108, the image shooting control of the second lens is realized, and the terminal functions are enriched.

In step 102, when the preset trigger information is monitored, preset object information is acquired and output, the preset object information is object information of at least one photographed object in a first image and/or a second image, and the second image is a history image photographed by a second lens when the first lens photographs the first image.

The terminal acquires a first image and a second image after monitoring preset trigger information in a display interface of the first image, and then acquires object information of at least one shot object from the first image and/or the second image. There are various kinds of object information, such as an object avatar, an object text label, and the like.

In operation, the terminal may acquire at least one photographed object from only the first image; the terminal may acquire at least one photographed object only from the second image; the terminal can acquire at least one shot object from the first image and the second image simultaneously, and in this case, the at least one shot object can be an object which appears in the first image or the second image independently or an object which appears in the first image and the second image simultaneously.

Referring to fig. 3, which is a flowchart illustrating another method of processing image data according to an exemplary embodiment, the operation of acquiring and outputting preset object information may be implemented by steps 1021 to 1024 as follows:

in step 1021, a first image and a second image are acquired.

There are various ways for the terminal to acquire the first image and the second image, for example:

the first acquisition mode is as follows: the second image is a history image shot by the second lens when the first image is shot by the first lens, and the second image is associated with the first image, so that the terminal can establish a corresponding relation between the first image identifier of the first image and the second image identifier of the second image after the first image and the second image are acquired.

After monitoring the preset trigger information in the display interface of the first image, the terminal can acquire the first image identifier of the first image, search the pre-established corresponding relationship between the first image identifier and the second image identifier according to the first image identifier, determine the second image identifier corresponding to the first image identifier, determine the second image according to the second image identifier, and acquire the second image.

The second acquisition mode is as follows: the terminal may store the first image and the second image in a preset folder, and the terminal records a correspondence between a folder identifier of the preset folder and a first image identifier of the first image.

After monitoring the preset trigger information in the display interface of the first image, the terminal can acquire the first image identifier of the first image, search the corresponding relation between the pre-established folder identifier and the first image identifier according to the first image identifier, determine the folder identifier corresponding to the first image identifier, determine the preset folder according to the folder identifier, determine the first image in the preset folder according to the first image identifier, and determine the second image in the preset folder by using an exclusion method.

In step 1022, at least one subject is determined based on the first image and the second image.

There are various ways for the terminal to determine at least one object to be photographed based on the first image and the second image.

For example, referring to fig. 4, which is a flowchart illustrating another method for processing image data according to an exemplary embodiment, the operation of the terminal determining at least one photographed object according to the first image and the second image may be implemented by: in step 1022-1, each of the photographed objects in the first image and the second image is identified; in step 1022-2, photographing information of each subject is acquired; in step 1022-3, the shooting information of each object is matched with the first preset shooting information condition, and at least one object whose shooting information matches with the preset shooting information condition is determined.

With respect to the above step 1022-1, when the photographic subject is a person, each of the photographic subjects in the first image and the second image may be recognized by a face recognition method.

For the step 1022-3, the preset shooting information conditions corresponding to different types of shooting information are different. When the shooting information includes the shooting duration, the first preset shooting information condition includes a preset shooting duration condition, and the first preset shooting duration condition may include: the shooting duration of the shot object is greater than the shooting duration threshold, or the shooting duration of the shot object meets a preset shooting duration range, and the like; when the photographing information includes photographing position information, the first preset photographing information condition includes a preset photographing position information condition, and the preset photographing position information condition may include: the shot object is located in a designated area in the image, the position relation between one shot object and other shot objects meets the preset position relation, and the like.

In operation, when the photographing information includes photographing position information, step 1022-3 may be implemented by: firstly, determining whether the shooting duration of each shot object is matched with a preset shooting duration condition; and secondly, determining at least one shot object with the shooting duration matched with the preset shooting duration condition.

When the photographing information includes the photographing position information, step 1022-3 may be implemented by: firstly, determining whether the shooting position information of each shot object is matched with a preset position information condition; and determining at least one shot object of which the shooting position information is matched with the preset position information condition.

Based on the settings of step 1022-1 to step 1022-3, the terminal is enabled to have a function of determining at least one object to be photographed by determining whether the photographing information matches the preset photographing information condition, and the terminal function is enriched.

For another example, referring to fig. 5, which is a flowchart illustrating another method for processing image data according to an exemplary embodiment, when the terminal stores a reference image of at least one preset object, the terminal may determine at least one photographed object according to the first image and the second image by: in step 1022-4, for each reference image of the preset object, determining whether the first image and the second image include the reference image of the preset object; in step 1022-5, if the first image and/or the second image includes a reference image of the preset object, determining the preset object as a photographed object; in step 1022-6, at least one photographed object is determined according to the preset object.

For example, the terminal stores a first facial avatar of a first person and a second facial avatar of a second person in advance, determines whether the first facial avatar is included in the first image and the second image, and determines that the first person is a photographed object if the first image and/or the second image is determined to include the first facial image; similarly, the terminal determines whether the first image and the second image include the second facial avatar, and if the first image and/or the second image include the second facial image, the terminal determines that the second person is the shot object.

Based on the settings of step 1022-4-step 1022-6, the terminal is enabled to have a function of determining at least one photographed object by determining whether the first image and the second image include a reference image of a preset object, and the terminal function is enriched.

In an alternative embodiment, the terminal determines at least one shot object according to the first image and the second image

In an alternative embodiment, before performing step 1022-4-step 1022-6, i.e., before determining at least one photographed object from the first image and the second image, the terminal may further perform the following operations: firstly, acquiring a historical image set shot by a terminal in a preset time period; secondly, acquiring at least one preset object of which the shooting information is matched with a second preset shooting information condition in the historical image set; finally, a reference image shot for at least one preset object is acquired from the historical image set.

The history image set may only include history photos taken by the terminal within a preset time period, may only include history videos taken by the terminal within the preset time period, or may include both the history photos and the history videos taken by the terminal within the preset time period.

There are various kinds of shooting information such as shooting time, shooting duration, shooting times, shooting frequency, shooting position information, and the like. And the second preset shooting information conditions corresponding to different shooting information are different. For example, when the photographing information includes a photographing duration, the second preset photographing information condition includes a preset photographing time condition, and the preset photographing time condition may include: the shooting duration in the image shot last time is greater than the duration threshold, the total shooting duration in the preset historical period is greater than the duration threshold, and the like; when the shooting information includes the shooting times, the second preset shooting information condition includes a preset shooting time condition, and the preset shooting time condition may include: the total shooting times in a preset historical time period are larger than a time threshold value and the like; when the photographing information includes a photographing frequency, the second preset photographing information condition includes a preset photographing frequency condition, and the preset photographing frequency condition may include: the total shooting frequency in a preset historical time period is greater than a frequency threshold value and the like; when the photographing information includes the photographing position information, the second preset photographing information condition includes a preset photographing position information condition, and the preset photographing position information condition may include: the preset object is located within a preset region of the image, and so on.

The preset object may be a person, an animal, a scene, etc. There are various reference images of the preset object, such as a photograph, an avatar, etc. of the preset object. After acquiring at least one preset object in the historical image set, the terminal may intercept a reference image photographed for the at least one preset object from the historical image set. In operation, the terminal may further receive a reference image of a preset object input by a user.

Based on the setting of the three steps, the terminal has the function of acquiring the reference image shot aiming at least one preset object from the historical image set shot in advance, and the terminal function is enriched.

In step 1023, object information of at least one object to be photographed is acquired.

There are various kinds of object information such as facial avatar, photograph, text, and the like.

There are various ways in which the terminal acquires the object information of the subject. For example, when the object information is a facial avatar, the terminal may capture the facial avatar of the object in the first image or the second image by means of screenshot after determining the object, so as to obtain the facial avatar of the object.

For another example, the terminal presets a corresponding relationship between an object identifier of the provided object and object information, after the object is determined, searches the preset corresponding relationship between the object identifier of the object and the object information according to the object identifier of the object, and determines the object information corresponding to the object identifier, thereby obtaining the object information of the object.

In step 1024, object information of at least one object to be photographed is output.

The terminal outputs the object information of at least one shot object after acquiring the object information of at least one shot object.

There are various ways in which the terminal outputs the object information of at least one object to be photographed. For example, object information of at least one object to be photographed is displayed on a display interface of the first image. Illustratively, referring to fig. 6, which is a schematic view of a display interface of a first image according to an exemplary embodiment, referring to fig. 6, the terminal displays facial head images of a plurality of subjects on the display interface of the first image. As another example, the terminal may output the object information content of at least one photographed object by voice.

In an alternative embodiment, when the preset object information acquired by the terminal when performing step 102 is object information of at least two objects to be photographed, referring to fig. 7, which is a flowchart illustrating another method for processing image data according to an exemplary embodiment, the operation of acquiring and outputting the preset object information by the terminal may be implemented as follows: in step 1025, acquiring shooting information of each of at least two shot objects; in step 1026, at least two pieces of shooting information are sorted to generate a shooting information sequence; in step 1027, object information of at least two objects to be photographed is sequentially displayed according to the photographing information sequence.

Based on the settings of the steps 1025 to 1027, the terminal has the functions of sequencing the shooting information of at least two shot objects and sequentially displaying the object information of at least two shot objects according to the obtained shooting information sequence, so that the intelligent display of the object information of at least two shot objects is realized, the intelligent degree of the terminal is improved, and the user experience is improved.

For the above step 1027, there are various shooting information, such as a shooting time length, a shooting number of times within a preset history period, a shooting frequency within a preset history period, and the like. When the shooting information is the shooting duration, the terminal can sort at least two shooting durations according to the sequence from long to short of the shooting durations to generate a shooting duration sequence; when the shooting information is the shooting times within the preset duration, the terminal can sort at least two shooting times according to the sequence of the shooting times from the maximum shooting time to the minimum shooting time to generate a shooting time sequence.

In step 103, target object information determined by a user according to preset object information is acquired.

After the terminal outputs the preset object information, namely after the terminal outputs the object information of at least one shot object, the user can select the target object information from the object information of at least one shot object output by the terminal, determine the target shot object corresponding to the target object information as the center of gravity of image display, and input the target object information to the terminal.

There are various ways in which a user inputs target object information to a terminal. For example, referring to fig. 6, when the terminal displays a facial avatar of at least one subject on the display interface of the first image, the user may input target subject information to the terminal by clicking a target facial avatar; or, an input box is arranged on the display interface of the first image, and a user can input target object information to the terminal in a mode of triggering preset options by inputting the target object information in the input box; alternatively, the user may input the target object information to the terminal by means of voice input.

In step 104, the first image data of the first image and the second image data of the second image are processed according to the target object information to obtain target image data, and the target image data takes a target object corresponding to the target object information as a display center of gravity.

After acquiring target object information determined by a user according to preset object information, the terminal processes first image data of the first image and second image data of the second image according to the target object information to obtain target image data with a target shot object corresponding to the target object information as a display gravity center. When the target image is displayed based on the target image data, the target subject is highlighted in the target image.

In operation, referring to fig. 8, which is a flowchart illustrating another method for processing image data according to an exemplary embodiment, as shown in fig. 8, the terminal processes the first image data of the first image and the second image data of the second image according to the target object information, and the operation of obtaining the target image data may be implemented by the following steps 1041 and 1042:

in step 1041, the first image data and the second image data are processed to obtain composite image data.

And processing the first image data and the second image data to realize the synthesis of the first image and the second image. When the shooting angle of view of the obtained composite image is larger than the shooting angle of view of the first image and the shooting angle of view of the second image respectively, an image with a larger angle of view range is obtained by the method. This process is prior art and is not described herein in detail in the embodiments of the present disclosure.

In step 1042, display position data of the target object in the synthesized image data is modified to obtain target image data, where the target object in the target image corresponding to the target image data is displayed in the image center area.

Based on the setting of the step 1041 and the step 1042, the target photographed object is displayed in the image center area of the target image, the target photographed object is highlighted, and the terminal functions are enriched.

Referring to fig. 9, which is a flowchart illustrating another method for processing image data according to an exemplary embodiment, in fig. 9, the terminal processes the first image data of the first image and the second image data of the second image according to the target object information, and the operation of obtaining the target image data may be implemented by the following steps 1041, 1043 and 1044:

In step 1043, the number of designated images for displaying the target photographic subject in the composite image data is determined.

In step 1044, the other image data except the designated image data in the composite image data is blurred, so that target image data is obtained, in which the other objects located around the target object in the target image corresponding to the target image data are blurred and displayed.

Based on the settings of the step 1041, the step 1043 and the step 1044, the focusing display of the target shot object in the target image is realized, and the terminal functions are enriched.

In the embodiment of the disclosure, after the preset trigger information is monitored in the display interface of the first image, the object information of at least one photographed object in the first image and/or the second image is acquired and output, and the first image data and the second image data are processed according to the target object information selected by the user to obtain the target image data with the target photographed object as the display center of gravity, so that the target image can highlight the target photographed image.
