Referring to fig. 1, a flowchart of an image processing method according to a first embodiment of the present invention is shown, which may specifically include the following steps:
In the embodiment of the invention, when a user needs to take a picture and triggers the mobile terminal to open a shooting preview interface, the mobile terminal may first acquire user characteristic attributes, such as user gender, user age, user skin, user height, user body type, and the like. In practical applications, different user groups or user individuals usually have shooting preferences corresponding to group characteristics or personal characteristics of the user, such as specific postures, expressions and the like, and a beautiful image processing effect after shooting, such as low image brightness, bright image tone and the like, so that the mobile terminal can firstly obtain the user characteristic attributes, and then subsequently determine how to provide a targeted posture guidance for the user according to the characteristic attributes of the user who needs to shoot at present, and how to perform targeted post-processing on the shot image.
And 102, determining shooting parameters and first processing parameters corresponding to the user characteristic attributes.
In the embodiment of the present invention, the mobile terminal may store the shooting parameters and the first processing parameters corresponding to different user characteristic attributes in advance, where each shooting parameter and each first processing parameter may be preset according to different user groups, and of course, may also be obtained by learning and analyzing after the mobile terminal collects favorite habits of individual users with different user characteristic attributes for a long time, which is not specifically limited in this embodiment of the present invention.
The shooting parameters can represent a target posture which accords with the user preference, namely a posture which is provided for the user to make reference, so that the user can be subjected to targeted shooting guidance in the aspects of standing position, posture, expression and the like. The first processing parameter may include at least one processing parameter corresponding to an image processing effect, such as a processing parameter corresponding to a caricature filter effect, a processing parameter corresponding to a face brightening effect, and the like.
And 103, when the user posture in the shooting preview interface is matched with the target posture corresponding to the shooting parameters, shooting to obtain a target image.
In the embodiment of the invention, the mobile terminal can provide the target posture corresponding to the shooting parameter for the user so that the user can obtain the shooting suggestion information for guiding the posture, and then the user can adjust the posture of the user according to the shooting suggestion information provided by the mobile terminal, wherein the posture comprises a standing position, a posture, an expression and the like.
And 104, processing the target image according to the first processing parameter.
In the embodiment of the present invention, after obtaining the target image, the mobile terminal may process the target image according to the first processing parameter corresponding to the current user, that is, may process the target image into an image processing effect that is preferred by the current user, so as to obtain the processed target image.
In the embodiment of the invention, the mobile terminal can firstly acquire the user characteristic attribute, then determines the shooting parameter and the first processing parameter corresponding to the user characteristic attribute, and then shoots to acquire the target image when the user posture in the shooting preview interface is matched with the target posture corresponding to the shooting parameter, and can process the target image according to the first processing parameter. In the embodiment of the invention, the mobile terminal can take the target posture indicated by the shooting parameter corresponding to the user characteristic attribute as the reference of the shooting user, and then can shoot the target image when the user posture is matched with the target posture, and then the mobile terminal can process the target image according to the first processing parameter corresponding to the user characteristic attribute, so that the processed target image is more in line with the preference of the user, and thus, the satisfaction degree of the user on the final image can be improved, and the shooting efficiency is improved.
Example two
Referring to fig. 2, a flowchart of an image processing method according to a second embodiment of the present invention is shown, which may specifically include the following steps:
In the embodiment of the invention, the mobile terminal can have a voice recognition function, so that voice interaction can be carried out with a user. For example, when a user needs to take a picture, the mobile terminal can be awakened to enter an intelligent shooting state through specific awakening words such as 'help me take a picture', 'help me take a beauty picture', and the like, then a shooting preview interface is opened, and the user characteristic attribute starts to be acquired.
Furthermore, when the mobile terminal is used specifically, the mobile terminal can be further provided with a rotatable camera, so that when a user speaks, the sound production direction of the user can be identified, the current position of the user is determined, and the mobile terminal can control the rotatable camera to automatically align with the user, so that the user can be visually located in a shooting preview interface.
In addition, the mobile terminal can guide the user to feed back the shooting range through voice after the rotatable camera is aligned with the user, for example, the mobile terminal can play guiding voice: asking for which photo of a photo of big head, half-body, and whole body? If the user takes a full-body photograph through voice feedback, the mobile terminal can properly adjust the focal length, so that the full-body image of the user is in the photographing preview interface.
In practical application, the mobile terminal may obtain the user characteristic attribute in at least one of the following manners, including:
the first implementation mode comprises the following steps: performing face feature detection in a shooting preview interface to obtain face features of a user; and determining the characteristic attribute of the user according to the face characteristic of the user.
The second implementation mode comprises the following steps: collecting user voice information; carrying out voiceprint recognition on the user voice information to obtain voiceprint characteristics; and determining the user characteristic attribute according to the voiceprint characteristics.
In practical application, the mobile terminal can detect the face features of the user from the image, further analyze the face features of the user and determine the user feature attributes such as gender, age and the like of the user. The mobile terminal can also detect the voiceprint characteristics from the user voice information, further analyze the mechanical energy of the voiceprint characteristics and determine the user characteristic attributes such as the gender, the age and the like of the user. In practical application, the user characteristic attributes such as gender and age of the user are verified doubly through voiceprint recognition and face recognition, so that the accuracy of determining the user characteristic attributes can be improved, and the confidence of providing shooting suggestion information subsequently is improved.
Wherein the user characteristic attribute may include at least one of a user gender, a user age, a user skin, a user height, and a user body type. In specific application, the more contents are contained in the user characteristic attribute, the more accurate and detailed range of a user group to which the current user belongs can be determined by the mobile terminal. Furthermore, because the number of people who use the same mobile terminal to shoot is very limited, for example, specific people such as family, friends, and the like, in general, if the user characteristic attribute contains more content, the mobile terminal may even correspond a certain user characteristic attribute to a specific user individual, and further may perform targeted shooting suggestion information for the user individual.
In the embodiment of the present invention, the mobile terminal may store the shooting parameters and the first processing parameters corresponding to different user characteristic attributes in advance, and when a certain user uses the intelligent shooting function in the mobile terminal for the first time, the mobile terminal may determine the shooting parameters and the first processing parameters corresponding to the user characteristic attributes according to the user characteristic attributes of the current user, where the shooting parameters and the first processing parameters may be the shooting parameters and the first processing parameters corresponding to a user group to which the current user belongs, that is, the favorite habits of a certain group. The shooting parameters may specifically include at least one of a shooting position, a shooting angle, a shooting posture and a shooting expression.
After the mobile terminal shoots and processes the user each time, the mobile terminal can provide a plurality of images adopting different shooting modes and processing modes for the user to score, and then the mobile terminal can collect the shooting mode and the processing mode with higher user score according to the score of the user on each final image after multiple shooting processes, so that the shooting mode and the processing mode are taken as the favorite of the user to record, and the shooting parameters and the first processing parameters corresponding to the user characteristic attributes of the user are updated, so that the user can be provided with photos more conforming to the favorite of the user.
And step 203, outputting shooting suggestion information according to the shooting parameters.
In the embodiment of the invention, the mobile terminal can provide shooting suggestions which accord with the shooting parameters of the user for the current user in the modes of voice, characters, diagrams and the like. In practical applications, the step can be implemented by the following steps: generating a shooting suggestion text according to the shooting parameters; converting the shooting suggestion text into shooting suggestion voice; and playing shooting suggestion voice.
In one embodiment, before the user adjusts the gesture, the mobile terminal may generate a shooting suggestion Text according To shooting parameters of the user, for example, the shooting parameters may include a picture middle position, the mobile terminal may generate a shooting suggestion Text of "please stand at the picture middle position", and for example, the shooting parameters may include a smile expression, the mobile terminal may generate a shooting suggestion Text of "please keep smile", and then the mobile terminal may convert the shooting suggestion Text into shooting suggestion voice through a Text To Speech (Text To Speech) broadcast technology, so that before the user adjusts the gesture, the shooting suggestion voice may be broadcast To enable the user To adjust the gesture of the user according To a prompt of the shooting suggestion voice.
In another embodiment, the mobile terminal may detect a user gesture in the shooting preview interface in real time, and generate a shooting suggestion text according to a difference between a current user gesture and a target gesture indicated by the shooting parameters when detecting that the user gesture does not conform to the shooting parameters, for example, at least one of the following shooting suggestion texts:
shooting position suggestion text: please walk two steps ahead, ask your face to lean back.
Shooting angle suggestion text: please slightly lower the head and slightly raise the head to the right.
Shooting gesture suggestion text: please face me slightly to the left and slightly to the right.
Shooting a posture suggestion text: please lift the chest and contract the abdomen.
Shooting an expression suggestion text: please keep smiling.
And then the mobile terminal can convert the shooting suggestion text into shooting suggestion voice through a TTS (text to speech) broadcasting technology, so that the shooting suggestion voice can be broadcasted in the process of adjusting the posture of the user, and the user can adjust the posture of the user according to the prompt of the shooting suggestion voice.
And 204, when the user posture in the shooting preview interface is matched with the target posture corresponding to the shooting parameters, shooting to obtain a target image.
In the embodiment of the invention, when the user gesture in the shooting preview interface is matched with the target gesture corresponding to the shooting parameter, that is, the mobile terminal detects that the user is currently at the favorite position indicated by the shooting parameter, and puts out the favorite gesture, favorite expression and the like indicated by the shooting parameter, the mobile terminal can shoot, so that the target image which accords with the shooting preference of the current user is obtained.
In the embodiment of the present invention, the first processing parameter may include a processing parameter acting on a reference image whose first user score exceeds a preset score, and since the user may score at least two final images after shooting and processing the image each time, the first processing parameter may include a processing parameter acting on a reference image whose first user score exceeds the preset score, that is, the first user score corresponding to the reference image is relatively high, a processing effect presented in the reference image is preferred by the user, and accordingly, after obtaining the target image, the mobile terminal may process the target image according to the processing parameter acting on the reference image, that is, perform the same processing operation as the reference image, so that the first image meeting the image processing preference of the current user may be obtained.
At step 206, at least one second processing parameter other than the first processing parameter is selected from the preset image processing parameters.
In this embodiment of the present invention, a plurality of image processing parameters may be preset in the mobile terminal, where each image processing parameter corresponds to one or more image processing effects, and each image processing parameter may include a display attribute processing parameter and a portrait processing parameter, where the display attribute processing parameter may specifically include at least one of an image brightness processing parameter, an image saturation processing parameter, and an image hue processing parameter, the portrait processing parameter may specifically include at least one of a part contour processing parameter and a five sense organ processing parameter, and the five sense organ processing parameter may specifically include a local beautification operation on five sense organs, such as eyes, mouth, and nose, which is not specifically limited in this embodiment of the present invention.
Since the image processing effect corresponding to the first image may be one of various image processing effects that have been tried by the user so far, after the target image is obtained, the mobile terminal may further select at least one second processing parameter other than the first processing parameter from preset image processing parameters, that is, select at least one image processing effect that may not be tried by the user or that may be tried a few times.
And step 207, processing the target image according to each second processing parameter to obtain at least one second image.
In the embodiment of the present invention, the mobile terminal may respectively perform image processing operations corresponding to different second processing parameters on the target image, that is, may perform at least one image processing operation that may not be tried by the user or has a small number of attempts on the target image to obtain at least one second image, so that the user's beauty parameters may be updated and adjusted subsequently according to the rating feedback of the user on the first image and the at least one second image.
In the embodiment of the invention, the mobile terminal can display the first image and each second image for the user to check, the user can respectively score the first image and each second image and input the first image and each second image into the mobile terminal, and then the mobile terminal can acquire the second user score corresponding to the first image and each second image.
Step 209 determines a high-score image with a second user score greater than the first user score from the first image and each second image.
In the embodiment of the present invention, the mobile terminal may determine, from the first image and each second image, whether there is a high-score image with a second user score greater than the first user score, that is, whether there is an image with a score higher than that of the reference image, and if there is an image with a second user score greater than that of the first user score, select the image.
And step 210, updating the shooting parameters according to the user posture in the high-resolution image.
In the embodiment of the invention, if the first image and each second image have an image with a higher grade than the reference image, the mobile terminal can determine that the user posture in the high-resolution image is a favorite posture of the user compared with the reference image, and then the mobile terminal can replace the originally stored shooting parameters with the shooting parameters corresponding to the user posture in the high-resolution image, so that the shooting parameters can be updated. And when the user shoots again, shooting suggestions can be provided for the user according to the updated shooting parameters, and shooting guidance can be provided.
And step 211, updating the first processing parameter according to the second processing parameter corresponding to the high-resolution image.
In the embodiment of the present invention, the mobile terminal may replace the first processing parameter with the second processing parameter corresponding to the image processing operation that is performed on the high-resolution image, so that the update of the first processing parameter may be implemented. Further, when the user performs image processing after shooting again, the shot image may be processed according to the updated first processing parameter.
In the embodiment of the invention, the mobile terminal can firstly obtain the characteristic attribute of the user, then determines the shooting parameter and the first processing parameter corresponding to the characteristic attribute of the user, then outputs shooting suggestion information according to the shooting parameter to be used as a reference for the user to adjust the shooting posture, further shoots when the user posture in the shooting preview interface is matched with the target posture corresponding to the shooting parameter, obtains the target image, respectively carries out different processing on the target image according to the first processing parameter, then can obtain the grade of the user on the image processed in different modes, and further can update the shooting parameter and the first processing parameter according to the grade of the user. In the embodiment of the invention, the mobile terminal can provide a shooting suggestion which accords with the user preference for the user in the shooting stage according to the shooting parameters corresponding to the characteristic attributes of the user, and further can carry out processing which accords with the user preference on the target image according to the first processing parameters corresponding to the user adjustment attributes after the target image is obtained through shooting. Because the final image is obtained after shooting and processing based on the preference of the user, the satisfaction degree of the user on the final image can be improved, and the shooting efficiency is improved. In addition, the mobile terminal can update the shooting parameters and the first processing parameters according to the user scores corresponding to the final images with different processing styles, so that images more conforming to the user preference can be obtained when shooting and image processing are carried out again.
