The image processing method provided by the embodiment of the present application is described in detail below with reference to the accompanying drawings through specific embodiments and application scenarios thereof.
Referring to fig. 1, a flowchart illustrating steps of an image processing method according to an embodiment of the present application is shown.
The image processing method of the embodiment of the application comprises the following steps:
step 101: the first preview image and the second preview image are displayed.
The image processing method provided by the embodiment of the application is suitable for processing the preview image in the shooting process. In the case where the double exposure function of the camera is on, the image processing method shown in the embodiment of the present application is executed.
The displayed first preview image and the second preview image can both be images collected by a camera in the shooting process; one of the images may be a preview image acquired by the camera, and the other image may be an image stored locally in the electronic device or an image acquired by the server.
One of the first preview image and the second preview image is used as a top layer, namely a background image, and the other one is used as a bottom layer.
The first preview image is displayed on the second preview image in an overlapped mode, the transparency of the first preview image and the transparency of the second preview image can both be smaller than the preset transparency, and the purpose of setting the transparency of the first preview image smaller than the preset transparency is to prevent the image in the second preview image from being displayed through the first preview image. In an optional embodiment, the transparency of the first preview image and the transparency of the second preview image are both set to 0, and the transparency of the first preview image set to 0 may completely block the image in the second preview image. The first preview image and the second preview image may have transparency greater than the preset transparency.
The target preview image is at least one of the first preview image and the second preview image. In the system, a first preview image can be used as a top layer and a second preview image can be used as a bottom layer by default, namely, the first preview image is used as a target preview image; the system can also default to use the second preview image as a top layer, and the first preview image as a bottom layer, that is, the second preview image is used as a target preview image. Of course, without being limited thereto, the user may also manually switch the stacking order of the first preview image and the second preview image through the first input, thereby changing the target preview image. Furthermore, the user can select a target area in the target preview image while the system is triggered to change the target preview image through the first input. For example: the target area can be determined according to the touch position of the first input and the strength of the first input.
For example, the first preview image is used as a top layer, the second preview image is used as a bottom layer, and when the transparency of the first preview image is greater than a first preset value and the transparency of the second preview image is greater than a second preset value, the target image may be the first preview image or the second preview image.
For example, the first preview image serves as a top layer, the second preview image serves as a bottom layer, and when the transparency of the first preview image is smaller than a third preset value and the transparency of the second preview image is smaller than a fourth preset value, the target image may be the first preview image.
An exemplary schematic diagram of a position relationship between a first preview image and a second preview image is shown in fig. 2, where the first preview image covers the second preview image and is spaced from the second preview image by a certain distance, the first preview image 201 is used as a top layer, and the second preview image 202 is used as a bottom layer.
Step 102: a first input of a user is received.
The first input may be used to delineate a target region in a target preview image. The first input may include at least one of: the method comprises the following steps of operation of delineating a target area in a target preview image, operation of smearing the target area in the target preview image, pressing operation in the target preview image and the like, wherein the strength of the pressing operation and the radius of the target area can be in a direct proportion relation. The target area may be of any suitable shape, the size and shape of the target area being determined in dependence on the first input.
The first input may also be used to determine the target area while determining the target preview image.
The first input may also be used to determine the transparency of the target area.
A first preset control is displayed in the image processing interface and is a transparency adjusting inlet. The first preset control can be a sliding bar, and correspondingly the first input can be the transparency adjusted by adjusting the position of a cursor on the sliding bar; the first preset control may also be a preset button, and accordingly the first input may be an operation of manually inputting a target transparency or selecting a transparency from transparency options provided by the system after the user touches the button to trigger the system to display a transparency input box or transparency options.
As shown in the schematic diagram of the transparency adjustment interface in fig. 3, a user may perform a pressing operation on the first preset control in fig. 3 (a), and trigger the system to display a slider, and as shown in fig. 3 (b), the interface schematic diagram in which the slider is displayed may be used for setting the transparency of the target region by adjusting the position of the cursor on the slider.
The transparency is larger than the preset transparency, and the higher the transparency value is, the stronger the perspective effect is.
Step 103: in response to the first input, a transparency of a target region of the target preview image is adjusted.
If the setting input of the transparency of the target area by the user is not received, the transparency of the target area can be determined as the default transparency of the system. The specific value of the default transparency of the system can be flexibly set by those skilled in the art, so as to ensure that the image superimposed on the underlying layer is displayed.
Because the first preview image and the second preview image are overlapped and displayed, after a user demarcates a target area in the target preview image, the other preview image also corresponds to the corresponding target area, and after the transparency of the target area in the target preview image is adjusted during processing, an image in the target area in the other preview image can be shown through the target area in the target preview image, and finally the target image with the target area having a double exposure effect is obtained.
Illustratively, adjusting the transparency of the target area of the target preview image includes: and under the condition that the transparency of the target preview image is greater than the target transparency, turning down the transparency of the target area in the target preview image to the target transparency. And in the case that the transparency of the target preview image is smaller than the target transparency, the transparency of the target area in the target preview image is adjusted to be larger than the target transparency. The target transparency is the transparency of the target area set by the user through the first input, or the transparency of the target area in the system by default.
For example, the first preview image is used as a top layer, the second preview image is used as a bottom layer, and when the transparency of the first preview image is greater than a first preset value and the transparency of the second preview image is greater than a second preset value, the target image may be the first preview image or the second preview image. At this time, the transparency of the target area of the target preview image is adjusted, specifically, the transparency of the target area of the target preview image is adjusted to be small, so that the effect of double exposure is realized on the other parts except the target area.
For example, the first preview image serves as a top layer, the second preview image serves as a bottom layer, and when the transparency of the first preview image is smaller than a third preset value and the transparency of the second preview image is smaller than a fourth preset value, the target image may be the first preview image. At this time, the transparency of the target area of the target preview image is adjusted, specifically, the transparency of the target area of the target preview image is increased, so as to achieve the effect that the target area presents double exposure.
When the target image is generated, the image in the top layer is used as the background of the target image, and part of the image in the bottom layer is used as the image main body in the target image. For example: the first preview image is an A scenery spot image, the second preview image is a character image, and if the target area corresponds to the B area in the A scenery spot image and corresponds to the head area in the character image, the exposure effect of the character head image which is displayed in the B area of the A scenery spot image in a perspective manner is shown in the generated target image.
It should be noted that the image processing method provided in the embodiment of the present application is not limited to processing an image, and the method may be used to process each frame of image in a video, so as to finally obtain a video with a double exposure effect.
According to the image processing method provided by the embodiment of the application, the first preview image and the second preview image are displayed; receiving a first input of a user; the transparency of the target area of the target preview image is adjusted in response to the first input, a user can define a local area to set the transparency according to personalized requirements, and only the target area or only other areas except the target area in the adjusted target preview image show a double exposure effect, so that the personalized requirements of the user can be met, and the interest of image processing is improved.
When the image is processed, in addition to the first preset control shown in step 102, other controls for user interaction may be included in the image processing interface.
An exemplary map image processing interface schematic diagram is shown in fig. 4, an image processing interface includes a first preset control 401, a second preset control 402, and a third preset control 403, where the first preset control 401 is a transparency adjustment entry, the second preset control 402 is a layer position switching entry, and the third preset control 403 is a cancel target area entry, and a user may further interact with an electronic device by performing input on any preset control, and the following exemplary lists several interaction manners:

in this alternative embodiment, the first input is a selected operation of the second preset control 402. And after the display positions of the first preview image and the second preview image are updated, the second preview image is covered on the first preview image.
And a second substep: and receiving a second input, and adjusting the transparency of the target area of the second preview image under the condition that the second preview image is displayed on the first preview image in an overlapped mode.
A first preset control 401 is displayed in the image processing interface, and the first preset control 401 is a transparency adjustment entry. The first preset control can be a slider, and correspondingly, the second input can be the adjustment of the transparency by adjusting the position of a cursor on the slider; the first preset control may also be a preset button, and accordingly, the second input may be an operation of manually inputting a target transparency or selecting a transparency from transparency options provided by the system after the user touches the button to trigger the system to display a transparency input box or a transparency option.
After the target area and the target transparency are determined, the transparency of the target area of the second preview image needs to be adjusted to the target transparency, and a target image is generated.
Through the optional embodiment, the user can switch the display position between the two preview images according to the requirement, and the operation is flexible and the interestingness is strong.
In an optional embodiment, in the case that the target area is determined by the first input, after the step of determining the target area, the following step may be further included:
receiving a third input of a user to a third preset control;
wherein the third input may comprise at least one of: a pressing operation, a clicking operation, a sliding operation, or the like.
In response to a third input, the delineation of the target region is cancelled.
The third preset control can also be called a reset redrawing button, and the target area drawn on the current image processing interface is erased, and the first preview image covered on the upper layer is displayed in a full frame. The user may again perform the first input in the image processing interface, re-demarcating the target area.
According to the optional mode, the user can cancel the planned target area only by executing the third input, and the target area is planned again, so that the operation is convenient and fast.
In an optional embodiment, when the first preview image and the second preview image are acquired, a front-facing camera can be called to acquire the first preview image; and calling a rear camera to acquire a second preview image.
Certainly, the method is not limited to this, and two different front cameras can be called to respectively acquire the first preview image and the second preview image; or respectively calling two different rear cameras to respectively acquire the first preview image and the second preview image.
The mode of simultaneously calling the front camera and the rear camera to acquire two preview images has the advantages of convenient operation; on the other hand, scenes on the front side and the back side of the user can be synthesized into the target image, and the interestingness of shooting is increased.
In an optional embodiment, the first preview image is a preview image acquired by the first camera, an image acquired from a server, or a locally stored image; the second preview image is a preview image acquired by a second camera, an image acquired from a server or a locally stored image; wherein the first camera is different from the second camera.
In the optional implementation manner, under the condition that the preview image acquired by the front camera or the rear camera is not satisfied by the user, the target image can be generated by combining the locally stored image or the image acquired by the server, so that the satisfaction degree of the user on the target image can be improved. Moreover, user interaction with the electronic device may also be enhanced as the user needs to look for the preview image in a locally stored image.
In an alternative embodiment, in the case that the first preview image is a first video frame in a first video and the second preview image is a second video frame in a second video, the step of adjusting the transparency of the target region of the target preview image in response to the first input comprises the sub-steps of:
