Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. 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, a flowchart illustrating steps of an image processing method according to an embodiment of the present invention is shown, which may specifically include the following steps:
In the shooting process of the mobile terminal, in order to process the mobile elements in the images shot by the user, the mobile elements need to be recognized in advance. Therefore, the mobile terminal can acquire a plurality of images through the camera so as to identify the moving elements in the currently shot image.
Specifically, the mobile terminal can acquire an image which needs to be shot by a user through the camera, cache a plurality of images acquired by the camera to obtain a plurality of cache images, and compare the plurality of cache images, so that a mobile element in the image which needs to be shot is determined according to the position of each element in the plurality of cache images.
It should be noted that the moving element may be a pedestrian, a vehicle, an animal, or another movable object, which is not limited in the embodiments of the present invention.
And 102, if the shooting operation triggered by the user is detected, processing the moving elements in each cache image in the plurality of cache images to obtain a plurality of processed images.
The mobile terminal can detect the operation triggered by the user in real time, when the fact that the shooting operation triggered by the user is detected, the cache image shot at the moment and the cache images cached in the preset time length before the moment can be selected according to the moment corresponding to the shooting operation triggered by the user, the moving elements in each cache image are processed, processed images are obtained, and therefore the mobile terminal can be synthesized according to the processed images in the subsequent steps.
The mobile terminal may process the mobile element in a blurring manner, may also process the mobile element in a manner of adding a streamer effect, and of course, may also process the mobile element in other manners, which is not limited in this embodiment of the present invention.
Moreover, when the mobile terminal processes the mobile elements in the cache images, the mobile terminal can process the mobile elements in different cache images differently according to the time when the cache images are acquired and the time corresponding to the trigger shooting operation.
Specifically, when the mobile terminal performs blurring processing on the mobile element, blurring of the mobile element in different cache images may be performed to different degrees according to a difference between a time when each cache image is acquired and a time corresponding to a trigger shooting operation.
If the difference value between the moment of acquiring a certain cache image and the moment corresponding to the trigger shooting operation is larger, the blurring degree of a mobile element in the cache image is larger when the mobile terminal processes the mobile element; when the difference is smaller, the degree of blurring the moving element is smaller.
In addition, when the mobile terminal performs streamer processing on the mobile element, streamer effects of different degrees can be added to the mobile element in different cache images according to the difference between the time of acquiring each cache image and the time corresponding to the trigger shooting operation.
If the difference value between the moment of acquiring a certain cache image and the moment corresponding to the trigger shooting operation is larger, when the mobile terminal adds the streamer effect to the mobile element in the cache image, the streamer effect added to the mobile element is weaker; when the difference is smaller, the streamer effect added to the moving element is stronger.
It should be noted that, in the process of processing the mobile element by the mobile terminal, for each cache image, the mobile terminal may first determine a plurality of pixels corresponding to the mobile element in the cache image, and process each pixel corresponding to the mobile element, so that each pixel corresponding to the mobile element is subjected to blurring or streamer mediation effect processing, and finally, a processed image is obtained.
After processing each cache image, the mobile terminal obtains a plurality of processed images, and then may combine the plurality of processed images, so that a pixel corresponding to the processed moving element may be combined with a pixel corresponding to a scene blocked by the moving element, thereby obtaining a combined image.
Specifically, the mobile terminal may align the processed cache images to make the static elements in the cache images located at the same position, and then synthesize the pixels at the same position in the cache images to obtain the synthesized pixels. After the synthesis of each pixel is completed, the synthesized image may be obtained by combining the synthesized pixels.
In summary, in the image processing method provided in the embodiment of the present invention, the mobile terminal processes the moving elements in the multiple cache images and synthesizes the multiple processed images to obtain an image without the moving elements, so as to avoid replacing pixels corresponding to a partial region in the image, further avoid a situation that the replaced image still includes the moving elements, improve reliability of processing the moving elements, and improve flexibility of processing the moving elements.
Referring to fig. 2, a flowchart illustrating steps of an image processing method according to an embodiment of the present invention is shown, which may specifically include the following steps:
In the shooting process of the mobile terminal, the scenery to be shot needs to be collected through a camera of the mobile terminal, so that the image to be shot is obtained and displayed for a user. Therefore, before an image is captured by the camera of the mobile terminal, the camera of the mobile terminal needs to be turned on.
Optionally, the mobile terminal may detect a function starting operation triggered by a user, and when the function starting operation triggered by the user is detected, the camera of the mobile terminal is started, and the multiple cache images are acquired through the camera of the mobile terminal.
Wherein the function opening operation is to open a photographing function.
Specifically, after the mobile terminal detects that the user triggers a function starting operation for starting the shooting function, the camera can be started according to the function starting operation, the shooting interface is displayed for the user, after the camera is started, the camera can acquire an image of the current environment, and the mobile terminal can display the acquired image in the shooting interface so that the user can preview the image.
In addition, in the process of acquiring the image by the camera, the mobile terminal can cache a plurality of images acquired by the camera to obtain a plurality of cache images, and the mobile terminal can acquire the cache images, so that in the subsequent step, the mobile terminal can identify the mobile elements in the image to be shot according to the plurality of cache images.
Further, when it is detected that the mobile terminal turns on the camera, the mobile terminal may obtain a frame rate value, and obtain a plurality of cache images according to the frame rate value, so that the number of the obtained cache images matches the frame rate value. The frame rate value may range from 30Hz (hertz) to 120Hz, which is not limited in the embodiments of the present invention.
The mobile terminal can analyze each cache image according to the plurality of cache images acquired by the camera, and determine whether each element in the cache images is displaced, so as to determine the mobile elements in the cache images and complete the identification of the mobile elements.
It should be noted that each of the cache images acquired by the mobile terminal may include a plurality of elements, such as a static element and a moving element, where the static element may be a stationary scene, and correspondingly, the moving element may be an element that moves during the shooting process, such as a vehicle, a pedestrian, an animal, and the like, which is not limited in this embodiment of the present invention.
In practical application, the mobile terminal may select a reference image from the plurality of cache images, compare each cache image with the reference image, determine, according to positions of each element in each cache image and each element in the reference image, whether each element in the cache images includes a mobile element.
The reference image is a cache image initially acquired by the mobile terminal, that is, the cache image acquired by the mobile terminal when the camera starts focusing.
Optionally, a reference image is selected from the plurality of cache images, an initial position of each element in the reference image is determined, a moving distance of each element in the reference image is determined according to the plurality of cache images, and finally, an element of which the moving distance is greater than a preset threshold value is determined as a moving element.
Specifically, the mobile terminal may select a position where each element in the reference image is located as an initial position, compare the reference image with other cache images acquired by the mobile terminal, determine whether each element in the other cache images has moved, and further acquire a moving distance of each element. When the moving distance corresponding to a certain element is greater than a preset threshold, the element can be determined to be a moving element.
Further, since the mobile terminal can acquire a large number of cache images in a short time, in order to reduce the workload of the mobile terminal, the mobile terminal can select a part of cache images from the large number of cache images to compare with the reference images, so that the mobile element can be efficiently and quickly identified. For example, the mobile terminal may select one cache image to compare with the reference image every preset time.
Optionally, the mobile terminal may select at least one target image from the plurality of cache images according to the obtaining time of the plurality of cache images, compare each element in the at least one target image with each element in the reference image, and determine the moving distance of each element in the reference image.
After the mobile terminal identifies the mobile element, the mobile element can be marked, so that a user can check the identified mobile element in a shooting interface, and further select the processing effect of the mobile element.
Moreover, the mobile terminal may mark the mobile element in a variety of ways, for example, the mobile terminal may obtain an edge pixel of the mobile element and highlight the edge pixel. Of course, the mobile terminal may also mark the mobile element in other manners, which is not limited in the embodiment of the present invention.
It should be noted that, in practical applications, the mobile terminal may recognize a plurality of moving elements, and correspondingly, the mobile terminal may also display edge pixels of the plurality of moving elements respectively.
After the edge pixels of the mobile elements are highlighted, the mobile terminal can detect effect selection operation triggered by a user, and determine the processing effect of the mobile elements according to the effect selection operation triggered by the user, so that the processing effect of the mobile elements in the subsequent steps is determined according to the effect selection operation triggered by the user.
Wherein the processing effect may include at least one of a blurring effect and an adding streamer effect. Accordingly, when the user selects the processing effect, the user may select any one of the processing effects, and may also select two processing effects at the same time.
Step 205 is similar to step 102 and will not be described herein again.
And step 206, synthesizing the plurality of processed images to obtain a synthesized image.
Step 206 is similar to step 103 and will not be described herein.
After the mobile terminal obtains the synthesized image, the synthesized image may be displayed to a user, so that the user may determine whether the synthesized image meets the user's desire, and whether shooting and synthesizing are required again to obtain a new image, and the mobile terminal may process the synthesized image according to an operation triggered by the user, such as storing or deleting.
Optionally, the mobile terminal may display the synthesized image, and process the synthesized image according to a storage selection operation triggered by the user. Specifically, the mobile terminal may display the synthesized image on the shooting interface, and provide the user with options of storing and deleting, so as to perform an operation of storing or deleting the synthesized image according to the selection operation of the user, and complete the processing of the image.
Further, when it is detected that the user triggers a confirmation operation, the mobile terminal may store the synthesized image; however, when the user trigger cancel operation is detected, the mobile terminal may delete the synthesized image.
It should be noted that, after deleting the synthesized image, the mobile terminal may acquire the image to be photographed again through the camera of the mobile terminal, and the mobile terminal may acquire and acquire the image by using a higher frame rate value, so as to more accurately identify the moving element in the image.
In summary, in the image processing method provided in the embodiment of the present invention, the mobile terminal processes the moving elements in the multiple cache images and synthesizes the multiple processed images to obtain an image without the moving elements, so as to avoid replacing pixels corresponding to a partial region in the image, further avoid a situation that the replaced image still includes the moving elements, improve reliability of processing the moving elements, and improve flexibility of processing the moving elements.
Furthermore, by selecting the reference image and taking the position of each element in the reference image as the initial position, the judgment is performed according to the initial position of each element, whether each element in the cache image is a moving element is determined, the moving element in the image can be accurately identified, and the accuracy of identifying the moving element can be improved.
Furthermore, the cache images are selected according to the acquisition time corresponding to each cache image, and then the selected cache images are compared with the reference image to determine the moving distance of each element in the cache images, so that the time spent by the mobile terminal in determining the moving distance can be reduced, and the efficiency of determining the moving distance is improved.
Furthermore, by acquiring the edge pixels of the mobile element and highlighting the edge pixels, a user can preview the mobile element conveniently, and the user viscosity is improved.
Further, by detecting the effect selection operation triggered by the user, the mobile elements in the image can be processed according to the effect selected by the user, so that the flexibility of processing the mobile elements is improved.
