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 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.
Fig. 1 is a block diagram illustrating a photographing method according to an exemplary embodiment. The main executing body of the shooting method provided by the embodiment can be a terminal, such as a mobile phone, a tablet computer, a camera, and the like. As shown in fig. 1, the method of the present embodiment may include the following steps:
in step 101, when the target template image is determined to be in a backlight shooting environment currently, determining a target template image; the face brightness of the target face in the target template image is greater than the brightness threshold.
In this step, the present disclosure is not limited to a specific manner of determining that the imaging apparatus is in the backlight shooting environment. Alternatively, the backlight shooting environment may be determined by the intensity of the light obtained from the camera, for example, when the intensity of the light obtained from the camera exceeds an intensity threshold, the backlight shooting environment may be determined; alternatively, it may be determined that the image is in the backlight shooting environment by the light-dark contrast of the face and the background in the current preview image, for example, when the light-dark contrast of the face and the background in the current preview image exceeds a contrast threshold, it may be determined that the image is in the backlight shooting environment.
Alternatively, the target face in the target template image may be determined by a face recognition technique. The target face may be a face to be photographed, and the face to be photographed may be determined by a face in the current preview image. The face brightness of the target face in the target template image being greater than the brightness threshold may indicate that the target face in the target template image is not too dark, for example, the target template image may be a photograph taken in a non-backlit shooting environment.
In step 102, after the user inputs a shooting instruction, a shot image is generated according to the current preview image, and the color information of each region of the target face in the shot image is determined according to the color information of the corresponding region of the target face in the target template image.
In this step, the target face in the current preview image or the shot image may be determined by a face recognition technique. The shooting instruction may specifically be an instruction indicating that the user needs to save the current preview image as the shot image. The shot image is generated according to the current preview image, and the color information of each area of the target face in the shot image is determined according to the color information of the corresponding area of the target face in the target template image.
The shot image obtained by the shooting method in the related technology has the problem of darker face because the shot image is currently in a backlight shooting environment, wherein the face brightness of the target face in the shot image can be increased by determining the color information of each area of the target face in the shot image according to the color information of the corresponding area of the target face in the target template image, and the face brightness of the target face in the target template image is greater than a brightness threshold value, so that the problem of darker face in the shot image obtained in backlight shooting is avoided.
It should be noted that, for the region division of the target face, the disclosure may not be limited. Alternatively, the target face may be divided into a forehead region, a nose region, a mouth region, an eye region, an ear region, a chin region, a cheek region, a face region, an eyebrow region, and the like, according to the position of the five sense organs; or, the target face may be divided into different regions according to a preset shape with a preset size; alternatively, each sensory organ in the five sense organs may be located in one region, and the regions other than the region where the five sense organs are located may be further divided according to a preset shape with a preset size. The predetermined shape may be a regular shape such as a rectangle or a square. The larger the preset size is, the larger the granularity is, and the smaller the preset size is, the smaller the granularity is.
The region of the target face in the shot image may specifically be a region corresponding to the same position of the face of the target person in the target template image, and it should be noted that the target face in the shot image and the target face in the target template image are the same person, and the person is the target person. For example, the nose region of the target face in the target template image is a corresponding region of the nose region of the target face in the captured image. For another example, the forehead area of the target face in the target template image is a corresponding area of the forehead area of the target face in the captured image.
Alternatively, the color information may be, for example, color information represented by three primary colors of Red (Red, R) Green (Green, G) Blue (Blue, B).
According to the shooting method provided by the embodiment, when the target template image is determined to be in the backlight shooting environment, after a shooting instruction is input by a user, the shot image is generated according to the current preview image, the color information of each area of the target face in the shot image is determined according to the color information of the corresponding area of the target face in the target template image, and the face brightness of the target face in the target template image is greater than the brightness threshold, so that the face brightness of the target face in the shot image obtained in the backlight shooting environment can be increased, the problem that the face in the shot image obtained in the backlight shooting environment is dark is avoided, and the shooting effect is improved.
Fig. 2 is a block diagram illustrating a photographing method according to another exemplary embodiment. Referring to fig. 2, the method provided in this embodiment mainly describes an alternative implementation manner of generating a captured image according to a current preview image on the basis of the method shown in fig. 1. As shown in fig. 2, the forehead method of the present embodiment may include:
in step 201, when the target template image is determined to be in a backlight shooting environment currently, determining a target template image; the face brightness of the target face in the target template image is greater than the brightness threshold.
In this step, optionally, the target template image may be a template image in a template library, and the template library may be updated according to a user requirement, that is, one image is added as a template image to the template library, or an existing template image in the template library is removed from the template library.
Optionally, the determining the target template image specifically may include: and randomly selecting and determining a target template image from all template images of which the face brightness of the target face is greater than a brightness threshold value in the template library.
Optionally, because the brightness of different regions of the face may be different at different face angles, in order to further improve the shooting effect, determining the target template image may specifically include: and selecting a target template image from the template library according to the face angle of the target face in the current preview image, wherein the face angle of the target face in the target template image is consistent with the face angle of the target face in the current preview image. Here, the face angles may be the same, or the difference between the face angles is smaller than or equal to a preset difference.
It should be noted that the number of target template images may be one or more. When there are a plurality of target face regions, color information of the regions of the target face of the plurality of target template images may be superimposed on the captured image.
In step 202, the color information of each region of the target face in the current captured image corresponding to the current preview image is replaced with the color information of the corresponding region of the target face in the target template image, so as to obtain the current preview image.
In this step, the currently acquired image may specifically be an image acquired by a camera, and after the currently acquired image is processed, a currently previewed image may be obtained, and color information of each region of the target face in the currently previewed image is determined according to color information of a corresponding region of the target face in the target template image. Specifically, the color information of each region of the target face in the currently acquired image may be replaced with the color information of the corresponding region of the target face in the target template image, so as to obtain the current preview image. That is, the color information of each region of the target face in the current preview image is the same as the color information of the corresponding region of the target face in the target template image.
It should be noted that, the color information of the other regions except the region where the target face is located in the current preview image may be the same as or different from the color of the corresponding region in the target template image, and this disclosure does not limit this.
Considering that the target face in the template image may not be complete, the target face can be obtained after combining a plurality of template images. Therefore, in order to avoid the problem that a shot image obtained by only one target template image is not real enough to further improve the shooting effect, optionally, the target template image includes a first template image and a second template image; correspondingly, step 202 may specifically include: replacing the color information of a first area of a target face in a current acquired image with the first color information of a corresponding area of the target face in a first template image; correcting second color information of a second region of the target face in a second template image, wherein the contrast difference between the corrected second color information and the first color information is smaller than or equal to a difference threshold value; and replacing the color information of the second area of the target face in the current acquired image with the corrected second color information.
It should be noted that, because the contrast difference between different regions of the face in the captured image is not too large when the image is captured in the non-backlighted environment, here, the second color information of the second region of the target face in the second template image is corrected, so that the contrast difference between the corrected second color information and the first color information is smaller than or equal to the difference threshold, and the problem of poor capturing effect caused by the large contrast difference between the color information of the first region and the second color information of the second region in the current preview image can be avoided. Alternatively, the difference threshold may be related to a region, for example, the difference threshold of the nose tip region corresponding to the alar region may be greater than the difference threshold of the nose tip region corresponding to the forehead region.
The color information of each region of the target face in the current acquired image corresponding to the current preview image is replaced by the color information of the corresponding region of the target face in the target template image to obtain the current preview image, so that the face in the preview image presented to the user in the backlight environment is the face with improved brightness, and the effect of the preview image seen by the user is the effect of the shot image saved after the user inputs the shooting instruction, thereby improving the user experience.
In step 203, after the user inputs a photographing instruction, the current preview image is saved as a photographed image.
Optionally, after step 203, the following step 204 may be further included.
In step 204, the captured image is saved as a template image in a template library according to a template instruction input by the user, wherein the template instruction is used for instructing the captured image to be used as the template image.
In this step, the template command may be, for example, a command to store the captured image in a directory corresponding to the template library, or may be, for example, a command to score the capturing effect of the captured image to exceed a score threshold. Here, by saving the captured image as a template image in the template library according to a template instruction input by the user, the user can update the template image in the template library.
In the shooting method provided by this embodiment, the color information of each region of the target face in the current acquired image corresponding to the current preview image is replaced with the color information of the corresponding region of the target face in the target template image to obtain the current preview image, and after the user inputs a shooting instruction, the current preview image is stored as the shot image, so that the face in the preview image presented to the user in a backlight environment is the face with improved brightness, and the effect of the preview image seen by the user is the effect of the shot image stored after the user inputs the shooting instruction, thereby improving the user experience.
Fig. 3 is a block diagram illustrating a photographing method according to still another exemplary embodiment. Referring to fig. 3, the method provided in this embodiment mainly describes another alternative implementation of generating a captured image from a current preview image on the basis of the method shown in fig. 1. As shown in fig. 3, the method of this embodiment may include:
in step 301, when it is determined that the target template image is currently in a backlight shooting environment, determining a target template image; the face brightness of the target face in the target template image is greater than the brightness threshold.
It should be noted that step 301 is similar to step 201, and is not described herein again.
In step 302, after the user inputs a shooting instruction, the color information of each region of the target face in the current preview image is replaced with the color information of the corresponding region of the target face in the target template image, so as to obtain a shot image.
It should be noted that the specific manner of obtaining the photographed image is similar to the specific manner of obtaining the current preview image by replacing the color information of each region of the target face in the current acquired image with the color information of the corresponding region of the target face in the target template image, and is not described herein again.
Optionally, after step 302, the following step 303 may be further included.
In step 303, the captured image is saved as a template image in a template library according to a template instruction input by the user, where the template instruction is used to instruct the captured image to be the template image.
It should be noted that step 303 is similar to step 204, and is not described herein again.
In the shooting method provided by the embodiment, when it is determined that the current shooting environment is in the backlight shooting environment, the target template image is determined, after the user inputs a shooting instruction, the color information of each region of the target face in the current preview image is replaced by the color information of the corresponding region of the target face in the target template image, so that the shot image is obtained, the color information of each region of the target face in the shot image is determined according to the color information of the corresponding region of the target face in the target template image, and the face brightness of the target face in the target template image is greater than the brightness threshold, so that the face brightness of the target face in the shot image obtained in the backlight shooting environment can be increased, the problem that the face in the shot image obtained in the backlight shooting environment is dark is avoided, and the shooting effect is improved.
