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 invention.
Referring to fig. 1, fig. 1 is a flowchart of an image processing method according to an embodiment of the present invention, and as shown in fig. 1, an image processing method includes the following steps:
In this step, the mobile terminal may determine at least one target image area in the photographing preview interface.
The number of the target image areas may be one, two, or more, which is not limited in this embodiment of the present invention.
The manner of determining the target image area may be determined according to a selection operation of a user. The selection operation by the user may be a touch operation or a voice operation by the user. At least one target image area in the shooting preview interface is determined according to the selection operation of the user, so that the diversity or the layering sense of the image can be improved, the flexibility of image processing can be improved, and the image processing can better meet the requirements of the user. In addition, the interest, participation or achievement of the user in the shooting process can be enhanced, and therefore user experience is improved.

The other implementation mode is as follows: and determining all target image areas, and then respectively displaying the image parameter adjusting control corresponding to each target image area.
Since the image parameters involved in the image processing may include multiple items, each target image region may correspond to one image parameter adjustment control or multiple image parameter adjustment controls, and different image parameter adjustment controls are used for respectively controlling different image parameters. For example, image parameter adjustment control No. 1 is used to control the degree of blurring, image parameter adjustment control No. 2 is used to control the degree of beauty, and so on.
In addition, each target image area can also correspond to one image parameter adjusting control, and multiple image parameters can be controlled through the image parameter adjusting control.
The step enables the mobile terminal to flexibly and conveniently process the image in each target image area by respectively displaying the image parameter adjusting control corresponding to each target image area.

Then, the mobile terminal can send the processed shot image to a picture editor for coding, so as to generate a picture meeting the requirements of the user.

In this way, the embodiment of the invention can respectively perform image processing on each target image area in the shooting preview interface, so that the image has more diversity or layering, and the flexibility of image processing can be improved.
Referring to fig. 2, fig. 2 is a flowchart of another image processing method according to an embodiment of the present invention, and the embodiment of the present invention is different from the embodiment of the present invention shown in fig. 1 in that a technical solution for determining a target image area through a sliding operation of a user is provided. As shown in fig. 2, an image processing method includes the steps of:
In this step, the user may input a sliding operation on the shooting preview interface, and the mobile terminal may detect the sliding operation of the user on the shooting preview interface.
In this step, if the user inputs a sliding operation in the shooting preview interface and the sliding trajectory is a closed trajectory, the mobile terminal may determine an area surrounded by the sliding trajectory of the sliding operation as the target image area.
In the embodiment of the invention, the mobile terminal determines the target image area through the sliding operation input by the user, so that the user can obtain the target area with any size or shape, and the user can select the target image area more flexibly.
In addition, the mobile terminal may provide some selectable region shapes for the user to select the target image region, for example, a circular region shape, a heart-shaped region shape, a square region shape, an elliptical region shape, or a flower region shape, etc. Therefore, the user can directly select the area shape to select the target image area according to the requirement, and the efficiency of selecting the target image area by the user is improved.
In addition, in order to make the user selection of the target image area finer, the mobile terminal may enlarge the image displayed on the photographing preview interface when the user selects the target image area, and may reduce the image displayed on the photographing preview interface to an initial size after the user has selected the target image area.
In the embodiment of the present invention, the number of the target image areas may be one, two, or more.
For convenience of understanding, the blurring process applied to the image according to the embodiment of the present invention will be described as an example. When the number of the target image areas determined by the mobile terminal is multiple, the mobile terminal can perform blurring processing on different target image areas to different degrees, so that the highlighting degree of each target image area in the shooting preview interface is different, and the image has diversity or layering.
If the user needs to select a plurality of target image areas, steps 201 to 202 may be repeatedly executed a plurality of times.
And step 203, respectively displaying the image parameter adjusting control corresponding to each target image area.
In this step, the mobile terminal may respectively display an image parameter adjustment control corresponding to each target image area in the shooting preview interface, so as to implement image processing on each target image area through the image parameter adjustment control. For example, the mobile terminal may respectively display the blurring degree adjustment control corresponding to each target image area in the shooting preview interface.

Thus, each target image region may correspond to an image parameter adjustment control or a plurality of image parameter adjustment controls, different image parameter adjustment controls being used to control different image parameters respectively. For example, each target image region may correspond to two image parameter adjustment controls, where the image parameter adjustment control No. 1 is a blurring degree adjustment control for controlling the blurring degree of the target image region, and the image parameter adjustment control No. 2 is a beauty degree adjustment control for controlling the beauty degree of the target image region, and so on.

And 204, respectively adjusting the image parameters of each target image area based on the image parameter adjusting control.
In this step, the mobile terminal may adjust the image parameters of each target image area based on the image parameter adjustment control. For example, the mobile terminal may adjust the blurring degree of each target image area separately based on the blurring degree adjustment control.
Optionally, the step of respectively adjusting the image parameter of each target image area based on the image parameter adjustment control includes:
detecting touch operation of a user on the image parameter adjusting control;
and adjusting the image parameters of the target image area corresponding to each image parameter adjusting control based on the detected touch operation.
In the embodiment of the invention, the user can input the image parameters of the target image area to the mobile terminal through the touch operation of the image parameter adjusting control, so that the user can input the image parameters of the target image area more intuitively and conveniently, and the user can flexibly input the image parameters of the target image area according to the self requirement, thereby further improving the flexibility of image processing.
The embodiment of the present invention may also be implemented in combination with the embodiment of the invention shown in fig. 1, and achieve the same beneficial effects, which are not described herein again to avoid repetition.
Optionally, a slider is arranged on the image parameter adjusting control;
the step of detecting the touch operation of the user on the image parameter adjusting control comprises the following steps:
detecting the dragging operation of a user on a sliding block on the image parameter adjusting control;
the step of adjusting the image parameters of the target image area corresponding to each image parameter adjustment control based on the detected touch operation includes:
if the dragging operation is detected, obtaining dragging parameters of the sliding block;
adjusting the image parameters of the target image area corresponding to each image parameter adjusting control according to the dragging parameters;
wherein the dragging parameter comprises a dragging direction and/or a dragging distance.
In the embodiment of the invention, a user can input dragging operation to the slider on the image parameter adjusting control, and the mobile terminal can adjust the image parameters of the target image area according to the dragging direction and/or the dragging distance of the dragging operation.
For example, a slider is disposed on the blurring degree adjustment control, and a position of the slider on the blurring degree adjustment control, that is, a dragging distance of the slider may reflect the blurring degree of the image. For example, the controllable range of the blurring degree adjustment control is 0 to 20, and the blurring degree of one unit is adjusted every time the slider moves by one unit length.
The dragging direction of the slider on the blurring degree adjusting control can also reflect the blurring degree of the image. For example, the slider slides upwards on the blurring degree adjustment control, which may indicate that the blurring degree of the image is enhanced; the sliding block slides downwards on the blurring degree adjusting control to express that the blurring degree of the image is weakened; and so on.
The embodiment of the present invention can also be implemented in combination with the embodiment of the present invention shown in fig. 1, and achieve the same beneficial effects, which are not described herein again to avoid repetition.

As shown in fig. 3, an image processing method includes the steps of:
In this step, the user may input a click operation on the shooting preview interface, and the mobile terminal may detect the click operation of the user on the shooting preview interface.
In this step, if the user inputs a click operation in the shooting preview interface, the mobile terminal may perform contour recognition on an operation area of the click operation.
Specifically, the mobile terminal can transmit the position coordinates of the user click operation to the bottom layer, and the bottom layer identifies the overall outline of the object in the operation area of the click operation by performing an outline identification algorithm on the coordinate area clicked by the user in the preview data, and can outline and display the overall outline of the object for the user.
And step 303, determining a region surrounded by the identified outline as a target image region.
In this step, the mobile terminal may determine an area surrounded by the identified outline as a target image area.
In addition, the mobile terminal can also track the object, and specifically, the mobile terminal transmits the object contour identified by the contour identification algorithm to the object tracking algorithm to track the object. When the object is dynamic, the mobile terminal can acquire the coordinates of the object in real time through an object tracking algorithm and adjust the target image area surrounded by the shooting preview interface in real time.
In the embodiment of the invention, the mobile terminal can determine the target image area through the click operation of the user, compared with the mode of determining the target image area through the sliding operation of the user, the operation is simpler and quicker, and the time spent by the user in selecting the target image area is shorter.
For convenience of understanding, the following description will be given taking an example of a case where the embodiment of the present invention is applied to a beauty process of an image. When the number of the target image areas determined by the mobile terminal is multiple, the mobile terminal can perform different degrees of beauty treatment on different target image areas, so that the beauty degrees of all the target image areas in the shooting preview interface are different, and the image has more diversity or layering.
If the user needs to select a plurality of target image regions, steps 301 to 303 may be repeatedly executed a plurality of times.
And 304, respectively displaying the image parameter adjusting control corresponding to each target image area.
In this step, the mobile terminal may respectively display an image parameter adjustment control corresponding to each target image area in the shooting preview interface, so as to implement image processing on each target image area through the image parameter adjustment control. For example, the mobile terminal may respectively display the beauty degree adjustment control corresponding to each target image area in the shooting preview interface.
The image parameters involved in the image processing may comprise a plurality of terms, such as two or more of a blurring degree, a beauty degree, a brightness size, a sharpness size, a contrast size, a saturation size and a chrominance size.
Thus, each target image region may correspond to an image parameter adjustment control or a plurality of image parameter adjustment controls, different image parameter adjustment controls being used to control different image parameters respectively. For example, each target image region may correspond to two image parameter adjustment controls, where the image parameter adjustment control No. 1 is a blurring degree adjustment control for controlling the blurring degree of the target image region, and the image parameter adjustment control No. 2 is a beauty degree adjustment control for controlling the beauty degree of the target image region, and so on.
