Detailed Description

In order to make the technical solutions of the present disclosure better understood by those of ordinary skill in the art, the technical solutions in the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings.

It should be noted that the terms "first," "second," and the like in the description and claims of the present disclosure and in the above-described drawings are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the data so used is interchangeable under appropriate circumstances such that the embodiments of the disclosure described herein are capable of operation in sequences other than those illustrated or otherwise described herein. 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.

It should be noted that the shooting control method according to the embodiment of the present disclosure may be executed by a shooting control apparatus according to the embodiment of the present disclosure, where the shooting control apparatus may be implemented in software and/or hardware, and the shooting control apparatus may be configured in an electronic device, where the electronic device may display a shooting preview interface, and the electronic device may be a terminal device having a shooting function. The terminal device may include, but is not limited to, a smart phone, a tablet computer, and the like.

Fig. 1 is a flowchart illustrating a photographing control method according to an exemplary embodiment, and as shown in fig. 1, the photographing control method proposed by the present embodiment includes the following steps.

In step 101, a control and a current shooting image are displayed on a shooting preview interface.

For example, the shooting preview interface may be a preview interface when a camera of the electronic device shoots a picture or a video, or may be a preview interface when the electronic device is connected with other video or image acquisition devices.

In the embodiment of the disclosure, when a user needs to shoot an image through an electronic device, the user can start a camera of the electronic device in multiple ways, and correspondingly, the electronic device obtains the current shot image of the camera and displays a shooting preview interface on the electronic device.

For another example, in the process of using the smart phone by the user, if the user is inconvenient to operate the smart phone, the user may start the shooting function of the smart phone by inputting a voice command, specifically, the user may input a voice message of "please open the shooting function of a certain short video application", and correspondingly, the smart phone analyzes the voice message to obtain a corresponding control command, and turns on the camera according to the corresponding control command, and displays the current image shot by the camera on the shooting preview screen of the short video application.

In order to improve the effect of shooting images or recording videos of a user, controls with various functions are further displayed on the shooting preview interface, so that the user can conveniently adjust shooting parameters through the controls, or perform image processing on the shot images, for example, add various special effects to the shot images.

Wherein, the control refers to the encapsulation of data and methods. The control may have its own properties and methods, the properties being simple visitors of the control data, and the methods being some simple and visible functions of the control.

For example, the currently shot image is displayed on the shooting preview interface, and a control for adjusting the function parameters of the image processing function for the currently shot image, or a control for switching the image processing function, etc. may also be displayed.

For example, after a user triggers a shooting button in a camera application in the electronic device, the electronic device starts a camera, collects an image through the camera, and displays a shot current image on a shooting preview interface in the camera application, where an exemplary view of the shooting preview interface is shown in fig. 2, and as can be seen from fig. 2, the shooting preview interface can display the current shot image, a control a for adjusting function parameters of an image processing function, and a control B for switching to an adjacent image processing function.

In step 102, a specified object among the currently captured images is identified.

In the embodiment of the disclosure, after the currently shot image is displayed on the shooting preview interface, the specified object in the currently shot image can be identified through the identification module in the electronic device based on the characteristics of the specified object.

Wherein the designated object includes, but is not limited to, a fingertip. For example, the fingertips include a single fingertip or multiple fingertips.

For example, after the current captured image is displayed on the capture preview interface, the electronic device may detect the area of the quasi-straight line by using the contour image based on the contour features of the fingertips, and identify the fingertips in the current captured image by combining the areas of the quasi-straight line.

For another example, after the current captured image is displayed on the capture preview interface, the identification module in the electronic device may identify whether a fingerprint exists in the current captured image, and if so, may determine that a fingertip exists in the current captured image, and further identify the fingertip in the current captured image.

For another example, after displaying the current captured image on the capture preview interface, the electronic device may identify a fingertip in the current captured image based on a barycentric distance method.

For example, after the currently-photographed image is displayed on the photographing preview interface, the electronic device may detect a region of the hand based on skin color detection, then calculate a center of gravity of the region of the hand, then intensively detect a point farthest from the center of gravity at an edge point of the region of the hand, where the point is a fingertip candidate position, then determine whether a distance from the candidate point to the center of gravity is greater than 1.6 times an average distance from the edge to the center of gravity, and if so, may identify the point as a fingertip.

In step 103, the current display position of the designated object on the shooting preview interface is determined.

In an embodiment of the present disclosure, a designated object in a currently captured image is recognized, an image position of the designated object in the currently captured image may be determined, and a current display position of the designated object on a capture preview interface is determined according to the image position based on a position mapping relationship between the currently captured image and the capture preview interface.

For example, a fingertip in the current captured image is recognized, coordinates (x, y) of the fingertip in the current captured image can be determined, and based on the position mapping relationship between the current captured image and the capture preview interface, the current display position of the fingertip on the capture preview interface can be determined to be (x, y).

As one possible implementation example, the specified object in the current shot image is identified, the coordinate of the specified object in the current shot image can be determined, the coordinate of the specified object in the shooting preview interface can be determined based on the same reference coordinate system of the current shot image and the shooting preview interface which is established in advance, and then the current display position of the specified object on the shooting preview interface can be determined.

As another possible implementation example, a specified object in the currently captured image is identified, the image position of the specified object in the currently captured image may be determined, and the image position of the specified object in the currently captured image may be directly used as the current display position of the specified object on the capturing preview interface. For example, the upper right position of the subject in the currently captured image is specified, that is, the current display position of the subject on the capture preview interface is specified to the upper right.

In step 104, if the control is determined to be triggered according to the current display position of the specified object and the position of the control, executing the operation corresponding to the control.

In the embodiment of the disclosure, after the current display position of the designated object on the shooting preview interface is determined, whether the current display position of the designated object is within a preset area range of a control position in the shooting preview interface can be detected, if so, it can be judged that the control in the shooting preview interface is triggered, and then the electronic device executes an operation corresponding to the control. Specific implementation modes can refer to the following embodiments.

For example, the coordinates (x, y) of the fingertip in the current captured image may be determined, and when the coordinates (x, y) of the fingertip are detected to be within the range of the top-right button area (top, right) in the capture preview interface, it may be determined that the control in the capture preview interface is triggered, and then the electronic device performs an operation of adjusting the function parameter of the corresponding image processing function in the control or an operation of switching to an adjacent image processing function in the control.

As a possible implementation example, after determining the current display position of the designated object on the shooting preview interface, it may be detected whether the current display position of the designated object on the shooting preview interface coincides with the position of the control in the shooting preview interface, and if the current display position of the designated object on the shooting preview interface coincides with the position of the control in the shooting preview interface, it may be determined that the control is triggered, and then the operation corresponding to the control is executed.

As another possible implementation example, after the current display position of the designated object on the shooting preview interface is determined, it may be determined that a coincidence area between the current display position of the designated object on the shooting preview interface and a position of a control in the shooting preview interface exceeds a preset threshold, and a duration of the coincidence area exceeding the preset threshold exceeds a preset duration, and if yes, it may be determined that the control is triggered, and then the operation corresponding to the control is executed.

In one embodiment of the present disclosure, to prompt the user whether the control is triggered, for the control, the control is displayed in a first display before the control is triggered and in a second display after the control is triggered. And the display styles of the controls in the first display mode and the second display mode are different. For example, the color of the controllable control may be white before the control is not triggered and yellow after the control is triggered.

According to the shooting control method provided by the embodiment of the disclosure, a control and a current shooting image are displayed on a shooting preview interface; identifying a specified object among the currently photographed images; determining the current display position of a specified object on a shooting preview interface; and if the control is determined to be triggered according to the current display position of the specified object and the position of the control, executing the operation corresponding to the control. Therefore, according to the method and the device, the current display position of the designated object on the shooting preview interface is determined, the control is determined to be triggered according to the current display position of the designated object and the position of the control, and then the operation corresponding to the control is executed, so that a user can trigger the function control in the shooting preview interface in a remote operation mode, the user can trigger the control in a non-contact mode conveniently, the problem of poor shooting experience of the user caused by the fact that the user frequently walks to the device to trigger the control is avoided, and the shooting experience of the user is improved.

Fig. 3 is a flowchart illustrating a photographing control method according to a specific embodiment according to an exemplary embodiment. As shown in fig. 3, the shooting control method of the present disclosure includes the steps of:

in step 301, a control and a current shot image are displayed on a shot preview interface.

And the control is used for indicating to adjust the function parameters of the current image processing function.

In the embodiment of the disclosure, a user can start a camera to shoot an image by triggering a camera application button in an electronic device, correspondingly, the electronic device can obtain the size of the currently shot image, then adjust the size of the currently shot image according to the size of a shooting preview interface, and further display the currently shot image with the same size as the shooting preview interface on the shooting preview interface, so that the shooting preview interface and the currently shot image have the same size.

The image processing function refers to a function that can process a currently shot image so as to present an effect of the currently shot image. The image processing functions include, but are not limited to, beauty, makeup, body beauty, filters, and the like. Wherein, the beautifying includes but not limited to skin grinding, skin whitening and the like; makeup includes, but is not limited to, lip makeup, eyebrow makeup, eye makeup, facial makeup, etc.; body beauty including but not limited to long legs, thin waist, thin face, small head, swan neck, etc.; filters include, but are not limited to, motion pictures, film time, texture, nature, and the like.

For example, the image processing function is a beauty processing function, the user can adjust the beauty degree of the beauty processing function according to the requirement, and correspondingly, the electronic device will beautify the face part in the current shot image according to the beauty parameters of the beauty processing function used by the user.

For example, the image processing function is a long-leg function, and generally, the length effect is different for different values of the functional parameter corresponding to the long-leg function, and generally, the greater the value of the functional parameter of the long-leg function is, the longer the length of the user's leg in the currently captured image is.

The current image processing function is an image processing function currently used for a currently captured image. The image processing function used for the currently captured image is triggered by the user.

The control in this embodiment may be set in a first operation area on the shooting preview interface, where the first operation area may be transparent and covers the currently shot image.

In an embodiment of the present disclosure, the first operation area may be displayed on the shooting preview interface after the user triggers the current image processing function. That is, after receiving the trigger function for the current image processing, the first operation region transparent and overlaid on the current captured image may be displayed on the capture preview interface in response to the trigger instruction.

In one embodiment of the present disclosure, there are various ways in which the current image processing function is triggered, for example as follows:

as an example, the trigger instruction for the current image processing function may be obtained by means of a voice instruction.

Specifically, the user can input the function name of the current image processing function in a voice mode, correspondingly, the electronic device recognizes the voice information input by the user, determines a control instruction corresponding to the voice recognition result, and when the control instruction is determined to be a trigger instruction for the current image processing function, can display a first operation area which is transparent and covers the current shot image on the shooting preview interface.

For example, the user needs to use the long leg function for the current captured image, the user can input voice data of "use the long leg function for the image", correspondingly, the electronic device takes the long leg function as the currently triggered image processing function, and can display a first operation area which is transparent and covers the current captured image on the capture preview interface.

As another example, the shooting preview interface may further include a second operation area, where the second operation area includes: the method comprises the steps that a touch control corresponding to a current image processing function receives touch operation aiming at the touch control, triggers a trigger instruction aiming at the current image processing function according to the touch operation, and displays a first operation area which is transparent and covers the current shooting image on a shooting preview interface.

The shooting preview interface further comprises a second operation area, wherein the second operation area comprises: a touch control corresponding to the first image processing function. For example, the second operating area may be understood as a cosmetic panel.

For example, as shown in fig. 2, the beauty panel includes: and the touch control corresponds to the body beautifying function in the first operation area.

For example, according to the requirement of the user, the function control corresponding to the long leg function in the beauty options on the shooting preview interface can be touched by the user, then the electronic device can receive touch operation aiming at the long leg function, then a trigger instruction aiming at the long leg function is triggered according to the touch operation, and in response to the trigger instruction, a first operation area which is transparent and covers the current shooting image is displayed on the shooting preview interface.

In one embodiment of the present disclosure, in order to facilitate the user to know the currently triggered image processing function, in addition to displaying the control in the first operation area, the name of the image processing function and the current value of the function parameter of the image processing function may be displayed in the first operation area.

Here, it is to be understood that the first operation region may be displayed at a preset position of the photographing preview screen by default. In this embodiment, in order to facilitate the user to remotely trigger the control in the first operation region, preferably, the preset position may be the top of the shooting preview interface.

In an embodiment of the present disclosure, in order to facilitate that a user may adjust the display position of the first operation region as desired, the position of the first operation region on the shooting preview interface of the embodiment may be adjustable.

As an exemplary embodiment, after a transparent first operation area is displayed on a photographing preview interface, when it is detected that a drag operation is performed on the first operation area, the first operation area is moved according to the drag operation; when the fact that the dragging operation is stopped being executed on the first operation area is detected, the first operation area is controlled to stay at the current position of the shooting preview interface, and therefore a user can move the first operation area on the shooting preview interface to a position suitable for self operation according to self requirements, and the user can conveniently conduct remote triggering on a control in the first operation area.

Specifically, after the transparent first operation area is displayed on the shooting preview interface, a user can perform mirror image dragging on the first operation area according to the needs of the user, when the electronic device detects that the user performs mirror image dragging on the first operation area, the first operation area can be moved according to the dragging operation, and when the electronic device detects that the dragging operation is stopped being performed on the first operation area, the first operation area can be controlled to stop at the current position of the shooting preview interface.

For example, the user may drag the first operation region to a top position in the shooting preview interface through mirror dragging; for another example, the user may drag the first operation area to a left position in the shooting preview interface through mirror image dragging; for another example, the user may drag the first operation region to a right position in the photographing preview interface through a mirror drag.

In step 302, a specified object among the currently captured images is identified.

Wherein the designated object includes, but is not limited to, a fingertip.

For example, after the currently captured image is displayed on the capture preview interface, the electronic device may identify a fingertip in the currently captured image based on a barycentric distance method. For example, after the currently-photographed image is displayed on the photographing preview interface, the electronic device may detect a region of the hand based on skin color detection, then calculate a center of gravity of the region of the hand, then intensively detect a point farthest from the center of gravity at an edge point of the region of the hand, where the point is a fingertip candidate position, then determine whether a distance from the candidate point to the center of gravity is greater than 1.6 times an average distance from the edge to the center of gravity, and if so, may identify the point as a fingertip.

For another example, after a girl image is displayed on the shooting preview interface, the identification module in the electronic device may identify whether a fingerprint exists in the girl image, and if so, may determine that a fingertip exists in the girl image, and further identify the fingertip in the girl image.

In step 303, the current display position of the designated object on the shooting preview interface is determined.

For another example, when a fingertip in the current captured image is recognized, the midpoint position of the fingertip in the current captured image can be determined, and the midpoint position of the fingertip in the current captured image can be used as the midpoint position of the fingertip on the capture preview interface.

In step 304, if it is determined that the control is triggered according to the current display position of the designated object and the position of the control, a value of the functional parameter of the current image processing function is adjusted to obtain an adjusted functional parameter.

In an embodiment of the disclosure, in order to prompt a user that a designated object has entered a first operation area, after a transparent first operation area is displayed on a shooting preview interface, if it is detected that a current display position is within the first operation area, a contour corresponding to the designated object is acquired, and the contour is displayed in a preset manner.

The preset mode is a preset mode for displaying the outline of the designated object, and the preset mode may be a mode for displaying the outline corresponding to the designated object in a preset color, for example, the outline of the designated object may be displayed in a red, yellow or blue mode.

In the embodiment of the present disclosure, when the designated object is a fingertip, the image operation region of the hand corresponding to the fingertip can be determined according to the currently-captured image, and then the contour corresponding to the finger can be determined according to the image operation region.

For example, as shown in fig. 4, after a transparent first operation region is displayed on the shooting preview interface, when it is detected that the display position of the fingertip is within the first operation region, an image operation region of a hand corresponding to the fingertip can be determined according to the current shooting image, then an outline of the hand is determined according to the image operation region, and the outline is displayed by red edge painting.

It should be noted that after the first operation area is displayed on the preview shooting interface, if the second operation area is also displayed on the preview shooting interface, the second operation area may generally affect the display of the currently shot image in the shooting preview interface, that is, the second operation area may block part of the content of the currently shot image. In order to reduce the influence of the second operation area on the display of the current shot image in the shooting preview interface, in one embodiment of the present disclosure, a hiding instruction may be received, where the hiding instruction is used to instruct hiding the second operation area, and the hiding processing may be performed on the second operation area in response to the hiding instruction.

It will be appreciated that there are a variety of ways in which the user input hides the second operating region, examples of which are illustrated below:

as an exemplary embodiment, a current gesture input by a user may be acquired, and if the gesture input by the user is consistent with a gesture corresponding to hiding the second operation region, it is determined that a hiding instruction for hiding the second operation region is received, and according to the hiding instruction, the second operation region in the preview shooting interface is hidden.

As another exemplary embodiment, the current voice information input by the user may be acquired, if the current voice information contains a keyword for hiding the second operation area, it is determined that the user inputs a hiding instruction for hiding the second operation area, and the second operation area in the preview shooting interface is hidden according to the hiding instruction.

As another exemplary embodiment, it may be determined whether the current display position of the designated object is within the first operation region, and if it is determined that the current display position of the designated object is within the first operation region, it is determined that a hiding instruction for hiding the second operation region is received, and in response to the hiding instruction, the hiding process is performed on the second operation region in the preview shooting interface.

For example, when the specified object is a fingertip and the current display position of the fingertip is not within the first operation region, as shown in a in fig. 5, it can be understood that the top region in a is the first operation region, and the region including the image processing functions such as one-key slimming, long leg, thin waist, and small head is the second operation region. Upon detecting that the current display position of the fingertip is within the first operation region, a hiding instruction for hiding the second operation region input by the user may be determined, and the bottom second operation region may be hidden, wherein an exemplary view of the photographing preview interface hiding the second operation region is shown as b in fig. 5.

In the embodiment of the disclosure, after the second operation area is subjected to hiding processing, in order to meet the requirement of displaying the second operation area again by a user, a display instruction may be received, where the display instruction is used to instruct to display the second operation area, and in response to the display instruction, the second operation area is controlled to be displayed again on the shooting preview interface. There are various ways to trigger the display instruction for displaying the second operation area, and the examples are as follows:

in some embodiments, if a click operation for the photographing preview interface is received, it is determined to receive a display instruction.

For example, after the second operation area is hidden, the user may click the shooting preview interface in a mirror image manner, when the electronic device receives a click operation of the user on the shooting preview interface through the electronic device, it may be determined to receive a command to display the second operation area, and the second operation area is controlled to be displayed again on the shooting preview interface in response to the display command.

In some embodiments, if a preset keyword is included in the received voice information, it is determined to receive a display instruction.

For another example, after the second operation area is hidden, the user may say "please help to open the second operation area", and then the electronic device may collect the "please help to open the second operation area" input by the user, and when the electronic device detects "open the second operation area", the electronic device may determine to receive the instruction to display the second operation area, and in response to the display instruction, control to display the second operation area again on the shooting preview interface.

In some embodiments, if the received gesture is consistent with a preset gesture corresponding to displaying the first operation area, it is determined to receive a display instruction.

For another example, after the second operation region is hidden, the user may make an "a" gesture, and the electronic device may receive the "a" gesture input by the user, and when it is detected that the received "a" gesture matches the preset gesture "a" corresponding to displaying the first operation region, it may be determined to receive a command to display the second operation region, and in response to the display command, the second operation region is controlled to be displayed again on the shooting preview interface.

In an actual application, the user may select, according to a requirement, a manner of triggering and displaying the second operation area, which is not specifically limited in this embodiment.

In the embodiment of the disclosure, in order to prompt a user that a control is triggered, before the value of the functional parameter is adjusted to obtain the adjusted functional parameter, the control can be controlled to be displayed in a second display mode, wherein the display styles of the control in the first display mode and the second display mode are different. And before the control is not triggered, the control is displayed in a first display mode.

For example, when the designated object touches the function control button, the function control button may be in a pressed state, that is, the control is displayed in the second display mode; and when the designated object leaves the function button, the function button can be in a normal state, namely the control is displayed in the first display mode. For example, as shown in fig. 6, a yellow color of the function control button may indicate that the function button is in a pressed state, and a white color of the function control button may indicate that the function button may be in a normal state.

In step 305, the current captured image is processed and displayed according to the adjusted functional parameters.

That is to say, the adjusted function parameters are obtained, and according to the adjusted function parameters, the electronic device performs processing operation on the current shot image, and then displays the current image after the operation.

For example, after the value of the functional parameter of the leg slimming function is adjusted to obtain the adjusted functional parameter, the leg slimming operation processing can be performed on the currently shot image according to the leg slimming function, and the currently shot image after the leg slimming operation processing is displayed.

According to the shooting control method provided by the embodiment of the disclosure, a control and a current shot image are displayed on a shooting preview interface, a specified object in the current shot image is identified, the current display position of the specified object on the shooting preview interface is determined, a first image processing function used currently is obtained, the value of a function parameter of the first image processing function is adjusted to obtain an adjusted function parameter, and the current shot image is processed and displayed according to the adjusted function parameter. According to the method and the device, the current display position of the designated object on the shooting preview interface is determined, the control is determined to be triggered according to the current display position of the designated object and the position of the control, and then the operation of adjusting the functional parameters corresponding to the image processing function is executed, so that the functional control of the image processing function in the shooting preview interface can be triggered by a user in a remote operation mode, the user can conveniently trigger the control in a non-contact mode, the problem of poor shooting experience of the user caused by the fact that the user frequently walks to the device to trigger the control is solved, the shooting experience of the user is improved, and the man-machine interaction performance is improved.

As shown in fig. 7, the specific implementation manner of adjusting the value of the functional parameter of the current image processing function to obtain the adjusted functional parameter is as follows:

in step 701, the duration of the control being triggered is determined according to the current display position of the specified object and the position of the control.

In the embodiment of the disclosure, if it is determined that the area of the position coincidence between the designated object and the control exceeds a preset threshold value and the time length of the area exceeding the preset threshold value exceeds a preset time length according to the current display position and the position of the control, it is determined that the control is touched; and determining a duration of time that the control is triggered.

That is to say, when the current display position of the designated object coincides with the position of the control, the area of the position coincidence between the designated object and the control exceeds the preset threshold, it can be determined that the control is triggered, and the duration of the triggering of the control can be determined according to the fact that the duration of the area exceeding the preset threshold exceeds the preset duration.

For example, as shown in FIG. 8, when the current position of the fingertip is in the first operation region

When the positions coincide, the finger tip and the finger tip can be judged

Whether the area of the coincidence exceeds a preset threshold value, if so, determining the area in the first operation area

The control is triggered, whether the duration of the area exceeding the preset threshold exceeds the preset duration or not is judged, and if yes, the situation that the area in the first operation area exceeds the preset threshold can be determined

The duration of time the control is triggered.

In order to avoid triggering invalid control operation, in the embodiment of the disclosure, if the current display position and positions of M controls all have position coinciding parts, determining an inclination angle of the designated object relative to a reference direction according to the current display position, where M is an integer greater than 1 and less than or equal to N, and outputting first prompt information if the inclination angle is less than a preset angle threshold, where the first prompt information is used to prompt that the operation is invalid and prompt to adjust the inclination angle of the designated object; and if the inclination angle of the specified object is larger than or equal to the preset angle threshold, outputting second prompt information, wherein the second prompt information is used for prompting that the operation is invalid and prompting to adjust the distance between the specified object and the shooting preview interface.

The manner of prompting information includes, but is not limited to, voice prompt, text prompt, etc.

For example, when it is detected that the user fingertip and the plurality of controls all have the overlapped portion, the tilt angle of the user fingertip relative to the reference direction can be determined according to the current position of the user fingertip, when the tilt angle is smaller than a preset angle threshold, the operation can be determined to be invalid, and the user is prompted with the 'fingertip direction error' in a voice mode, when the tilt angle is larger than or equal to the preset angle threshold, the operation can be determined to be invalid, and the user is prompted with the 'fingertip and shooting preview interface distance' in a voice mode.

For another example, when it is detected that the user fingertip and the plurality of controls all have the overlapped portion, the inclination angle of the user fingertip relative to the reference direction can be determined according to the current user fingertip position, when the inclination angle is smaller than the preset angle threshold, it can be determined that the operation is invalid, then the character of 'the fingertip direction is wrong' displayed in the shooting preview interface so as to prompt the user, when the inclination angle is larger than or equal to the preset angle threshold, it can be determined that the operation is invalid, and the character of 'the fingertip is away from the shooting preview interface' is displayed in the shooting preview interface so as to prompt the user.

In step 702, the current value of the functional parameter is obtained.

In some embodiments, after the current image processing function is obtained, a current value of a function parameter of the current image processing function may be obtained, where the current value of the function parameter may be a numerical value automatically generated by the electronic device according to the current captured image, for example, when a person in the current captured image is fat, the current value of the function parameter is large; when the figure in the current shot image is thin, the current value of the functional parameter is small.

In some embodiments, after the current image processing function is obtained, a current value of a function parameter of the current image processing function may be obtained, where the current value of the function parameter may be a function value used by a user last time.

For another example, after the current image processing function is obtained, the current value of the function parameter of the current image processing function may be obtained, where the current value of the function parameter may be a value in which the frequency of occurrence of the function value in the history of use of the user is the greatest.

In step 703, a value of the functional parameter is adjusted according to the current value and the duration to obtain an adjusted functional parameter.

For example, as shown in fig. 9, the current image processing function is a long-leg function, and the user can click the first operation area in the electronic device through the mirror imageIn (1)

And when the trigger duration is 1 second, the electronic device obtains a value of 65 as a function parameter for increasing the processing strength of the long leg, for example, from 64 current clicks to 65 current clicks.

For another example, as shown in fig. 9, when the current image processing function is a long-leg function, the user can click on the first operation region through the electronic device

And when the trigger duration is 2 seconds, the electronic device obtains a value of a functional parameter for reducing the processing strength of the long leg as 62 by clicking from the current 64 to the control 62.

Wherein the first image processing function is an image processing function adjacent to the current image processing function.

Wherein the first image processing function is an image processing function adjacent to the current image processing function. For example, the first image processing function includes, but is not limited to, face thinning, waist thinning, heightening, eye enlarging, and the like.

In step 1005, the current image processing function is switched to the first image processing function.

In step 1006, the currently captured image is processed and displayed according to the first image processing function.

For example, when the current image processing function is a long-leg function, a preview interface is taken, as shown in a in fig. 11, by touching the user's fingertip in a mirror image

After the control is obtained, if the next image processing function adjacent to the current image function is a waist-thinning function, the current image function may be switched to the waist-thinning function, where an exemplary diagram of the shooting preview interface after the image processing function is switched is shown as b in fig. 11.

In addition, fig. 11 shows

A control part for switching to the last image processing function, and detecting the mirror image touch of the specified object

After the control button is pressed, the last image processing function adjacent to the current image processing function can be obtained according to the current image processing function and the switching instruction for switching to the last image processing function, the current image processing function is switched to the last image processing function, and the current shot image is processed according to the switched image processing function. For example, the current image processing function is a small head function, the last image processing function adjacent to the current image processing function is a waist slimming function, and when it is detected that the current display position of the fingertip is located in the display area of the control switched to the last image processing function, the small head function is switched to the waist slimming function, and waist slimming processing is performed on the waist of the person in the currently captured image according to the waist slimming function.
