All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
The embodiment of the application provides an image synthesis method, an image synthesis device, a storage medium and terminal equipment.
Referring to fig. 1, fig. 1 is a schematic flowchart of an image synthesis method provided in an embodiment of the present application, where the image synthesis method is applied to a mobile terminal, the mobile terminal includes a first camera and a second camera, and the mobile terminal may be any intelligent electronic device with a mobile communication function, such as a smart phone, a tablet computer, a notebook computer, and the like. The specific flow of the image synthesis method provided by this embodiment may be as follows:
s101, a first image shot by a first camera and a second image shot by a second camera are obtained, wherein the first image comprises at least one target shooting object.
In this embodiment, the first camera and the second camera may be a front camera, a rear camera, or both, and when the first camera and the second camera are the front camera or the rear camera, the shooting views of the first camera and the second camera are different.
It is easily understood that, in the present embodiment, this step is the basis of all subsequent operations, and the first image captured by the first camera includes the target object desired by the end user and other objects.
And S102, transparency adjustment is carried out on the first image according to the target shooting object.
Further, the step S102 may specifically include:
determining a display area of each target shooting object on the first image;
and adjusting the transparency of the area except the display area in the first image to be a first preset transparency.
In this embodiment, the terminal identifies all the target photographic objects on the first image through the neural network learning model by inputting the acquired first image into the neural network learning model, and determines the display area of each target photographic object on the first image.
In this embodiment, the first preset transparency may be set manually, for example, 100%, and the terminal may highlight the target object with the best effect.
It should be noted that, in order to make the presentation effect of the target photographic object more realistic, the transparency of the display area may be converted.
Further, after the step of determining the display area of each target photographic object on the first image, the method may further include:
and adjusting the transparency of the display area to a second preset transparency.
In this embodiment, the relative value of the first transparency is greater than the relative value of the second transparency, and when the terminal sets the transparency of the display region, the value of the second preset transparency may be determined according to the color saturation of the display region, and generally, the higher the color saturation of the display region is, the larger the value of the second preset transparency may be, and the lower the color saturation of the display region is, the smaller the value of the second preset transparency may be.
And S103, generating the transparency-adjusted first image on the second image to obtain a composite image containing the target shooting object.
It should be noted that, when generating the composite image, the first image may be processed based on the shooting focal length and/or the image brightness of the first image, so as to make the rendering effect of the composite image more realistic.
For example, the step S103 may specifically include:
acquiring a first shooting focal length of a first image and a second shooting focal length of a second image;
adjusting the size of the first image with the adjusted transparency according to the first shooting focal length and the second shooting focal length to obtain a target image;
a target image is generated on the second image.
When the same object is photographed, the larger the photographing focal length is, the larger the occupation range of the object in the photographing picture is (i.e. the larger the image is), and the smaller the photographing focal length is, the smaller the occupation range of the object in the photographing picture is (i.e. the smaller the image is).
In this embodiment, in order to obtain a more beautiful composite image in the subsequent image composition step, an adjustment ratio is set according to the first photographing focal length and the second photographing focal length, and the size of the first image is adjusted to the optimal size by adjusting the ratio, so that when the first image with the adjusted transparency is generated on the second image, the image does not appear to be obtrusive.
Wherein, the step S103 may further include:
acquiring first image brightness of a first image and second image brightness of a second image;
adjusting the image brightness of the first image after the transparency is adjusted according to the first image brightness and the second image brightness to obtain a target image;
a target image is generated on the second image.
In this embodiment, it is easy to understand that when the first camera takes the first image and the second camera takes the second image, the brightness of the first image is different from that of the second image due to different ambient light, and the stronger the ambient light is, the higher the brightness of the image is, the weaker the ambient light is, and the lower the brightness of the image is.
In this embodiment, in order to obtain a more beautiful composite image in the subsequent image composition step, the brightness of the second image is adjusted according to the brightness of the second image, so as to ensure that the image is more harmonious when the target image is generated on the second image.
Specifically, when the target image with the adjusted image brightness is generated on the second image, the terminal determines the generation area on the second image according to the position of the target shooting object on the target image.
Further, after determining the generated region, the terminal may adjust the transparency of the generated region to a third preset transparency according to the color saturation of the generated region, so that the composite image is more attractive, wherein the relative value of the first transparency is greater than the relative value of the third transparency, and the relative value of the second transparency is greater than the relative value of the third transparency.
The step of adjusting the image size according to the shooting focal length and the step of adjusting the first image brightness according to the second image brightness may be performed simultaneously, or only the step of adjusting the image size according to the shooting focal length or only the step of adjusting the first image brightness according to the second image brightness may be performed.
In addition, after the image is synthesized, the user may further process the synthesized image, that is, after step S103, the method may further include:
displaying the composite image to a user on a current preview interface, wherein the current preview interface is provided with a plurality of beautifying keys;
acquiring a target beautifying key selected by a user from a plurality of beautifying keys;
and performing corresponding beautifying operation on the synthesized image according to the target beautifying key.
In this embodiment, when the terminal displays the composite image to the user on the current preview interface, a plurality of beautifying keys are provided on the preview interface, so that the user can perform corresponding beautifying operations on the composite image. The beautification key may instruct the terminal to perform gray level setting or color rendering (such as adding a filter) on the synthesized image, and the like.
It is easy to understand that the display mode of the beautification key can be pictures and/or characters corresponding to the effect, and the terminal user can select the required target beautification key by specifying gestures, voice and the like.
Specifically, when the user selects to perform gray level setting on the composite image, the terminal determines a display area of each target photographic object on the composite image, and then sets the gray level of an area except the display area in the composite image as a preset gray level.
Referring to fig. 2, fig. 2 is another schematic flow chart of an image synthesis method according to an embodiment of the present disclosure, where the image synthesis method is applied to a mobile terminal, where the mobile terminal includes a first camera and a second camera, and the mobile terminal may be any intelligent electronic device with a mobile communication function, such as a smart phone, a tablet computer, a notebook computer, and the like. The specific flow of the image synthesis method provided by this embodiment may be as follows:

It is easily understood that, in the present embodiment, this step is the basis of all subsequent operations, and the first image captured by the first camera includes the target object desired by the end user and other objects. For example, referring to fig. 3-a, the first camera and the second camera may be a front camera and a rear camera of the smartphone of fig. 3-a, the front camera takes a first image including a girl, and the radio takes an object in a second image taken by the rear camera.
S202, determining a display area of each target shooting object on the first image.
In this embodiment, the terminal identifies all the target photographic objects on the first image through the neural network learning model by inputting the acquired first image into the neural network learning model, and determines the display area of each target photographic object on the first image.

And the relative value of the first transparency is greater than the relative value of the second transparency, when the terminal sets the transparency of the display area, the value of the second preset transparency can be determined according to the color saturation of the display area, generally, the higher the color saturation of the display area is, the larger the value of the second preset transparency can be, the lower the color saturation of the display area is, and the smaller the value of the second preset transparency can be. For example, referring to fig. 3-a, the smartphone adjusts the transparency of the region other than the girl image to 100% to highlight the girl image with the best effect.
And S204, acquiring a first shooting focal length of the first image and a second shooting focal length of the second image.
The terminal performs the step of adjusting the image size according to the shooting focal length first, and then performs the step of adjusting the first image brightness according to the second image brightness.
When the same object is photographed, the larger the photographing focal length is, the larger the occupation range of the object in the photographing picture is (i.e. the larger the image is), and the smaller the photographing focal length is, the smaller the occupation range of the object in the photographing picture is (i.e. the smaller the image is).
S205, adjusting the size of the first image after transparency adjustment according to the first shooting focal length and the second shooting focal length to obtain a target image.
In this embodiment, in order to obtain a more beautiful composite image in the subsequent image composition step, an adjustment ratio is set according to the first photographing focal length and the second photographing focal length, and the size of the first image is adjusted to the optimal size by adjusting the ratio, so that when the first image with the adjusted transparency is generated on the second image, the image does not appear to be obtrusive. For example, referring to fig. 3-a, the smart phone resizes the transparency-adjusted first image according to the 2:1 adjustment ratio to obtain an image of the girl with a size reduced by one time.
S206, acquiring first image brightness of the target image and second image brightness of the second image.
In this embodiment, it is easy to understand that when the first camera takes the first image and the second camera takes the second image, the brightness of the first image is different from that of the second image due to different ambient light, and the stronger the ambient light is, the higher the brightness of the image is, the weaker the ambient light is, and the lower the brightness of the image is.
And S207, adjusting the brightness of the first image according to the brightness of the second image.
In this embodiment, in order to obtain a more beautiful composite image in the subsequent image composition step, the brightness of the second image is adjusted according to the brightness of the second image, so as to ensure that the image is more harmonious when the target image is generated on the second image.
And S208, generating the target image with the adjusted image brightness on the second image to obtain a composite image containing the target shooting object.
Specifically, when the target image with the adjusted image brightness is generated on the second image, the terminal determines the generation area on the second image according to the position of the target shooting object on the target image.
Further, after determining the generated region, the terminal may adjust the transparency of the generated region to a third preset transparency according to the color saturation of the generated region, so that the composite image is more attractive, wherein the relative value of the first transparency is greater than the relative value of the third transparency, and the relative value of the second transparency is greater than the relative value of the third transparency.
And S209, displaying the composite image to a user on a current preview interface, wherein the current preview interface is provided with a plurality of beautifying keys.
In this embodiment, when the terminal displays the composite image to the user on the current preview interface, a plurality of beautifying keys are provided on the preview interface, so that the user can perform corresponding beautifying operations on the composite image. The beautification key may instruct the terminal to perform gray level setting or color rendering (such as adding a filter) on the synthesized image, and the like.
