Detailed Description

Reference will now be made in detail to the exemplary embodiments, examples of which are illustrated in the accompanying drawings. When the following description refers to the accompanying drawings, like numbers in different drawings represent the same or similar elements unless otherwise indicated. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with the present invention. Rather, they are merely examples of apparatus and methods consistent with certain aspects of the invention, as detailed in the appended claims.

The embodiment of the disclosure provides a method for controlling a beautifying function, which can be implemented by a terminal, wherein the terminal can be a mobile terminal such as a mobile phone, a tablet computer or other video recording devices.

The terminal is provided with an application program for shooting videos, and the application program can be carried by the terminal or downloaded by a user. The application program has a beautifying function. When a user wants to shoot a video, the user clicks a recording button to enter a shooting view-finding interface, and then the user can click a starting button to enter a video recording interface. The terminal can decide to turn on or turn off the beautifying function according to the information of the face image in the image frame shot by the camera. After the recording is finished, the user can click the storage button to store the recorded video, and can click the release button to release the recorded video to the network.

Fig. 1 is a flowchart illustrating a method of controlling a beauty function, as shown in fig. 1, for use in a terminal, according to an exemplary embodiment, including the following steps.

In step 101, captured image frames are continuously acquired.

The image frames shot are image frames shot by a camera on the terminal.

In implementation, when a user wants to record a video, the user can open an application program for shooting the video, click a recording button to enter a shooting view interface, and at the moment, the terminal acquires an image frame shot by the camera, and the image frame is displayed on the shooting view interface after being transferred to a subsequent step for processing every time one image frame is acquired. When a user wants to start recording a video, the user clicks a start button to enter a video recording interface, at the moment, the terminal acquires an image frame shot by the camera, and the image frame is displayed on the video recording interface after being transferred to the subsequent steps for processing every time one image frame is acquired. The terminal continuously acquires image frames shot by the camera, and transfers to the subsequent steps for processing every time one image frame is acquired, and then the processed image frame is displayed on a shooting view-finding interface or a video recording interface.

In step 102, it is determined whether a face image meeting a preset size requirement is included in each captured image frame.

In implementation, after each captured image frame is obtained, the terminal uses the face recognition library to perform face recognition on the image frame, and when the face image cannot be recognized in the image frame, it is determined that the image frame does not include the face image meeting the size requirement. And when the face image is identified in the image frame, judging whether the size of the face image meets the preset size requirement.

The preset size requirement may be a minimum size requirement for the face image. Based on this minimum size requirement, it is possible to prevent the image frame containing only the face image of an excessively small size from being subjected to the beauty processing. The face image with the small size is processed, human eyes cannot see the effect, and the calculation amount of the terminal is increased. Moreover, when the size of the face image is too small, the user is not always shooting the face image video, and the beautifying function does not need to be turned on.

The preset size requirement may be a minimum area requirement for the face image, or a minimum number of pixel points included in the face image. The preset size requirement can also make requirements on the area of the face image and the number of contained pixel points, namely the area of the face image and the contained pixel points are required to reach a minimum value.

When the preset size requirement is the minimum area requirement on the face image, if only one face image is identified in the shot image frame, judging whether the area of the face image in the shot image frame is larger than the preset minimum area, and if not, determining that the face image meeting the preset size requirement is not included in the image frame. And if the area of the face image in the shot image frame is larger than the minimum area, determining that the image frame comprises the face image meeting the preset size requirement. When a plurality of face images are identified in a shot image frame, the area of each face image is sequentially compared with the minimum area, when the area of one face image is larger than the minimum area, the comparison of the area of the subsequent face image with the minimum area is stopped, and the image frame is determined to comprise the face image meeting the preset size requirement. And when the areas of all the face images in the shot image frame are smaller than or equal to the minimum area, determining that the image frame does not include the face images meeting the preset size requirement.

When the preset size requirement is the requirement for the minimum number of pixel points contained in the face image, if only one face image is identified in the shot image frame, whether the number of the pixel points contained in the face image in the shot image frame is greater than the preset minimum number is judged, and if the number of the pixel points contained in the face image in the shot image frame is not greater than the preset minimum number, the face image meeting the preset size requirement is determined not to be contained in the image frame. And if the number of pixel points contained in the face image in the shot image frame is more than the minimum number, determining that the image frame comprises the face image meeting the preset size requirement. When a plurality of face images are identified in a shot image frame, the number of pixel points contained in each face image is sequentially compared with the minimum number, when the number of the pixel points contained in one face image is greater than the minimum number, the comparison of the number of the pixel points contained in the subsequent face image with the minimum number is stopped, and the face image meeting the preset size requirement in the image frame is determined. And when the number of pixel points contained in all the face images in the shot image frame is less than or equal to the minimum number, determining that the face images meeting the preset size requirement are not included in the image frame.

When the preset size requirement requires that the area of the face image and the contained pixel points both reach a minimum value, if only one face image is identified in the shot image frame, firstly, whether the number of the pixel points contained in the face image in the shot image frame is greater than a preset minimum number is judged, and if not, the face image meeting the preset size requirement is determined not to be contained in the image frame. If the number of the pixel points contained in the face image in the shot image frame is larger than the minimum number, continuously judging whether the area of the face image in the shot image frame is larger than a preset minimum area, and if not, determining that the face image meeting the preset size requirement is not contained in the image frame. And when the number of pixel points contained in the face image in the shot image frame is more than the minimum number and the area is more than the minimum area, determining that the image frame comprises the face image meeting the preset size requirement. If a plurality of face images are identified in the shot image frame, the judgment is sequentially carried out on pixel points included in each face image and the area of the face image, when the number of the pixel points included in one face image is larger than the minimum number and the area is larger than the minimum area, the judgment of the subsequent face image is stopped, and the face image meeting the preset size requirement is determined to be included in the image frame. And when the number of pixel points contained in all the face images in the shot image frame and the area of the face images are not simultaneously larger than the minimum value, determining that the face images meeting the preset size requirement are not included in the image frame.

When the preset size requirement requires that the area of the face image and the contained pixel points both reach a minimum value, if only one face image is identified in the shot image frame, whether the area of the face image in the shot image frame is larger than the minimum area or not can be judged, and if the area of the face image in the shot image frame is not larger than the minimum area, the face image meeting the preset size requirement is determined not to be included in the image frame. If the area of the face image in the shot image frame is larger than the minimum area, whether the number of pixel points contained in the face image in the shot image frame is larger than the minimum number or not is continuously judged, and if the number of pixel points contained in the face image in the shot image frame is not larger than the minimum number, the face image meeting the preset size requirement is determined not to be contained in the image frame. And when the area of the face image in the shot image frame is larger than the minimum area and the number of the contained pixel points is larger than the minimum number, determining that the image frame comprises the face image meeting the preset size requirement. If a plurality of face images are identified in the shot image frame, the number of pixel points included in each face image and the area of the face image are sequentially judged, when the number of the pixel points included in one face image is larger than the minimum number and the area is larger than the minimum area, the judgment of the subsequent face image is stopped, and the face image meeting the preset size requirement is determined to be included in the image frame. And when the number of pixel points contained in all the face images in the shot image frame and the area of the face images are not simultaneously larger than the minimum value, determining that the face images meeting the preset size requirement are not included in the image frame.

Optionally, the on-off of the beautifying processing can be controlled through a switch control, and the processing of the process is performed only when the switch control is operated to be opened, and the corresponding processing process can be as follows: after receiving an automatic control instruction of a beautifying function, determining whether each shot image frame comprises a face image meeting the preset size requirement; and after receiving a beautifying function closing instruction, stopping the processing of determining whether each shot image frame comprises a face image meeting the preset size requirement, and closing the beautifying function if the beautifying function is in an opening state.

In implementation, a switch control of the beauty function is arranged on the terminal, and the switch control can be displayed in a shooting and framing interface and a video recording interface. The user can click the switch control to correspondingly control the beauty function. When a user wants to start the beauty function, the user clicks the switch control to start the beauty automatic setting function, at the moment, the terminal receives an automatic control instruction of the beauty function, the terminal does not start the beauty function immediately, but starts to determine whether each shot image frame comprises a face image meeting the preset size requirement, and determines whether to start the beauty function based on a determined result.

When a user wants to close the beautifying function, the user clicks the switch control to close the beautifying function, at the moment, the terminal immediately stops determining whether each shot image frame comprises a face image meeting the preset size requirement, if the beautifying function is in an open state, the terminal immediately closes the beautifying function, and if the beautifying function is in a closed state, the terminal maintains the beautifying function in the closed state.

In step 103, when it is determined that none of the image frames continuously shot within the preset duration includes a face image meeting the preset size requirement and the beautifying function is in an on state, the beautifying function is turned off, and the beautifying processing on the subsequently shot image frames is stopped.

Wherein the skin caring treatment comprises one or more of whitening treatment, skin grinding treatment, face thinning treatment, acne removing treatment, sharpening treatment, skin tendering treatment, pupil beautifying treatment and make-up treatment.

In implementation, when it is determined that a face image meeting the preset size requirement is included in the captured image frames, the terminal may determine whether a time interval from a last time when the captured image frames including the face image meeting the preset size requirement is detected is longer than a preset time interval. And when the time length is judged to be greater than the preset time length and the beautifying function is in the opening state, the terminal closes the beautifying function. And when the time length is judged to be greater than the preset time length and the beautifying function is in the closed state, the terminal maintains the beautifying function in the closed state. And when the duration is judged to be less than the preset duration, the terminal maintains the existing state of the beautifying function.

The preset duration is used for preventing pictures in the shooting view interface and the video recording interface from frequently flickering. In a shot image frame, sometimes a face image meeting the preset size requirement frequently appears and disappears, if the face image meeting the preset size requirement disappears, the beautifying function is immediately closed, and in this case, pictures in a shooting view interface or a video recording interface frequently flicker. Therefore, when the face image meeting the preset size requirement cannot be detected in all the image frames shot within the preset time, the beautifying function is closed, and the frequent flicker of the image can be prevented. The preset time is not suitable for being too long, otherwise, the beautifying function cannot be closed in time, and the effect of controlling the beautifying function cannot be achieved. The preset time is not too short, otherwise, the effect of preventing the picture from frequently flickering is not achieved. Optionally, the preset time period may be 2 s.

Optionally, after the beauty function is switched from the on state to the off state, a closing prompt message may be displayed on the shooting view interface and the video recording interface to prompt the user terminal that the beauty function is closed. The corresponding process may be as follows: and when it is determined that the image frames continuously shot within the preset time length do not comprise the face images meeting the preset size requirement and the beautifying function is in an open state, closing the beautifying function, stopping beautifying the subsequently shot image frames, and displaying closing prompt information on a shooting interface.

Wherein, the close prompt message is used for prompting that the current beautifying function is closed. The shooting interface can be a shooting view interface or a video recording interface.

In implementation, the close prompt message may be an image message or a text message. The display duration of the closing prompt message can be preset, and in order to prevent the closing prompt message from influencing the normal shooting of the user on the shooting view interface or the video recording interface, the preset display duration is not suitable to be too long. Optionally, the preset display time period may be 2 s. And when the self-beautifying function is switched from the open state to the closed state within the preset display duration, immediately stopping displaying the closing prompt message if the self-beautifying function is switched from the closed state to the open state.

And under the condition that the beautifying function is in the closed state, closing prompt information can be always displayed on the shooting view interface or the video recording interface, so that the user is reminded that the beautifying function is in the closed state at the moment. In order to prevent the closing prompt message from affecting the normal shooting of the user on the shooting view interface or the video recording interface, the closing prompt message can be displayed on the shooting interface or semi-transparently displayed on the shooting interface. As shown in fig. 4, the close prompt message "the beauty function is closed" is displayed in the lower right corner of the shooting interface.

Optionally, in order to ensure that the face images meeting the preset size requirement can be beautified, when the terminal detects the face images meeting the preset size requirement, the face beautifying function should be immediately started. The corresponding process may be as follows: and when any image frame is determined to comprise a face image meeting the preset size requirement and the beautifying function is in a closed state, starting the beautifying function, and performing beautifying processing on the image frame and the subsequently shot image frames.

In implementation, when a face image meeting the preset size requirement is detected in a shot image frame, if the beautifying function is in an off state, the beautifying function is immediately turned on, and the current time is determined as the time when the face image meeting the preset size requirement is detected in the shot image frame last time. And if the beautifying function is in the opening state, maintaining the beautifying function in the opening state, and determining the current time as the time when the face image meeting the preset size requirement is detected to be included in the shot image frame last time.

Optionally, in order to obtain a better shooting effect, only the face image in the image frame may be subjected to a beautifying process, and the corresponding process may be as follows: and when any image frame is determined to comprise the face image meeting the preset size requirement and the beautifying function is in a closed state, the beautifying function is started, and the beautifying processing is carried out on the image area corresponding to the face image in any image frame and the subsequently shot image frames.

In implementation, after detecting that a captured image frame includes a face image meeting a preset size requirement, an image area corresponding to the face image in the image frame is obtained through a face recognition library, where the image area may be a rectangular area, and then, only the image area corresponding to the face image in the image frame is subjected to beautifying processing.

When a plurality of face images are identified in a shot image frame, whether the size of each face image meets the preset size requirement or not needs to be judged, then, corresponding areas of all the face images meeting the preset size requirement in the image frame are obtained, and then, only the areas are subjected to beautifying processing. As shown in fig. 5, the terminal recognizes three face images, wherein the sizes of two face images meet the preset size requirement, so that the image areas corresponding to the two face images are subjected to the beautifying processing, and the other face image whose size does not meet the preset size requirement is not subjected to the beautifying processing.

Based on the setting, the face image in the video is more beautiful in beauty treatment, and the non-face image is more natural without beauty treatment.

Optionally, after the beautifying function is switched from the off state to the on state, an on prompt message may be displayed on the shooting view interface and the video recording interface to prompt the user terminal that the beautifying function is already on. The corresponding process may be as follows: and when any image frame is determined to comprise a face image meeting the preset size requirement and the beautifying function is in a closed state, starting the beautifying function, carrying out beautifying processing on any image frame and subsequently shot image frames, and displaying start prompt information on a shooting interface.

Wherein, the starting prompt message is used for prompting that the current beautifying function is closed. The shooting interface can be a shooting view interface or a video recording interface.

In implementation, the start prompt message may be image message or text message, and the type of the start prompt message may be consistent with that of the close prompt message. The display duration of the start prompt message can be preset, and in order to prevent the start prompt message from influencing the normal shooting of a user on a shooting view interface or a video recording interface, the preset display duration is not suitable to be too long. Optionally, the preset display time period may be 2 s. And when the self-beautifying function is switched from the closed state to the open state within the preset display duration, immediately stopping displaying the opening prompt message if the self-beautifying function is switched from the open state to the closed state.

And under the condition that the beautifying function is in the open state, always displaying the open prompt message on the shooting view interface or the video recording interface, thereby reminding the user that the beautifying function is in the open state at the moment. In order to prevent the start prompt message from influencing the normal shooting of the user on the shooting view interface or the video recording interface, the start prompt message can be displayed at the corner of the shooting interface or semi-transparently displayed on the shooting interface. The display modes of the closing prompt message and the opening prompt message can be consistent. As shown in fig. 6, the start prompt message "the beauty function is turned on" is displayed in the lower right corner of the shooting interface.
