Detailed Description
To make the objects, technical solutions and advantages of the present application more clear, embodiments of the present application will be described in further detail below with reference to the accompanying drawings.
The double exposure is an image photographing effect that can be traced back to the age of film photography, and after the age of digital photography, users still want to photograph images having the double exposure effect using a digital camera.
To meet the above-mentioned needs of users, many current photo-like applications support taking images with a double exposure effect. In general, when an image with a double exposure effect is shot, a user can trigger a shooting option, a control terminal shoots a first image, then the user can continue to trigger the shooting option, the control terminal shoots a second image, and after the two images are obtained, the terminal can fuse the two images by using a preset fusion algorithm, so that a fused image with the double exposure effect is obtained.
In practical application, after a first image is shot, the terminal enters a framing preview process, in the framing preview process, a camera of the terminal continuously shoots, wherein a framing video obtained by continuously shooting through the camera can be displayed in a framing preview interface, a user can know an image which can be shot by the current shooting terminal by observing the framing video displayed in the framing preview interface, and in the observation process, if the user finds that a picture in the framing video meets the shooting requirement of the user, the user can trigger a shooting option, so that the terminal is controlled to shoot a second image.
As can be seen from the above description, in the process of viewing and previewing, the user can only know the image that can be captured by the current shooting terminal according to the viewing video displayed on the viewing and previewing interface, but cannot know how the effect of the terminal after the image that can be captured is fused with the first image.
In other words, in the process of viewing and previewing, the user can only preview the shooting effect of the second image according to the viewing video displayed on the viewing and previewing interface, but cannot know the effect of the first image and the second image after being fused.
Because the user cannot know in advance how the effect of the first image and the second image is fused, the fused image obtained by fusing the first image and the second image by the terminal is often not in accordance with the shooting expectation of the user, and in this case, the user needs to shoot again, which undoubtedly affects the shooting flexibility.
In view of this, embodiments of the present application provide an image processing method, which can improve flexibility of capturing a double-exposure effect image. In the image processing method provided by the embodiment of the application, the terminal can acquire the framing video shot in the framing preview process and acquire the first image shot in advance, then the terminal can respectively perform fusion processing on the video frames in the first image and the framing video to obtain the fusion video with the double exposure effect, and in the framing preview process, the terminal can display the fusion video on the framing preview interface, so that a user can directly preview the effect of the fused image in the framing preview interface, therefore, the user can be prevented from shooting again, and the flexibility of shooting the double exposure effect image can be improved.
In the following, a brief description will be given of an implementation environment related to the image processing method provided in the embodiment of the present application.
As shown in fig. 1, the implementation environment may include a terminal 101, where the terminal 101 may be an electronic device such as a smartphone or a tablet computer, and the terminal 101 may be provided with a camera, and in practical applications, the camera provided in the terminal 101 may include at least one of a front camera and a rear camera. The terminal 101 may execute the image processing method provided by the embodiment of the present application.
Referring to fig. 1, a terminal 101 includes a processor and a memory connected by a system bus. Wherein the processor of the terminal 101 is used to provide computing and control capabilities. The memory of the terminal 101 includes a nonvolatile storage medium and an internal memory. The non-volatile storage medium stores an operating system and a computer program. The internal memory provides an environment for the operation of an operating system and computer programs in the non-volatile storage medium. The computer program is executed by a processor to implement an image processing method.
Those skilled in the art will appreciate that the configuration shown in fig. 1 is a block diagram of only a portion of the configuration associated with the present application, and does not constitute a limitation on the terminal 101 to which the present application is applied, and that a particular terminal 101 may include more or less components than those shown in the figures, or combine certain components, or have a different arrangement of components.
Referring to fig. 2, a flowchart of an image processing method provided in an embodiment of the present application is shown, where the image processing method can be applied to the terminal 101 in the embodiment shown in fig. 1. As shown in fig. 2, the image processing method may include the steps of:
As described above, in a possible implementation manner, when capturing an image with a double exposure effect, a user may trigger a capturing option provided by the terminal, the terminal may generate a capturing instruction after detecting that the capturing option is triggered, and capture a first image (i.e., a first image hereinafter) based on the capturing instruction, and after capturing the first image, the terminal may enter a framing preview process.
In another possible implementation manner, a user may select an image (i.e., the first image hereinafter) from a plurality of images stored in the terminal, and after selecting the first image, the terminal may enter a framing preview process, in other words, the terminal may provide an image selection interface, where the image selection interface displays a plurality of images, and after detecting a selection instruction for one image (i.e., the first image hereinafter) of the plurality of images based on the image selection interface, the terminal may enter the framing preview process.
As described above, after entering the view preview process, the camera of the terminal continues to capture the images, and in step 201, the terminal may acquire the view video captured continuously by the camera.
It should be noted that, in practical applications, a front camera and a rear camera may be disposed in the terminal, and optionally, after entering the viewing preview process, the terminal may control the front camera to continuously shoot, and may also control the rear camera to continuously shoot.
For example, in one possible implementation manner, after detecting that the shooting option is triggered, the terminal may control one of the front camera and the rear camera to shoot, so as to obtain a first image, and after obtaining the first image by shooting, the terminal may enter a framing preview process, where during the framing preview process, the terminal may control the other of the front camera and the rear camera to continue shooting.
As described above, the first image may be an image captured by the terminal before entering the framing preview process and after detecting that the capturing option is triggered.
In addition, the first image may also be an image selected by the user from a plurality of images displayed on the image selection interface.
And step 203, the terminal performs fusion processing on each video frame in the first image and the view video respectively to obtain a fusion video with double exposure effects.
In other words, in step 203, for each video frame in the viewfinder video, the terminal may perform the fusion processing on the video frame and the first image, thereby obtaining a fused video frame with a double exposure effect. The fused video is composed of a plurality of fused video frames obtained by the terminal.
Optionally, for each video frame in the viewfinder video, the terminal may obtain, from the first image, a second pixel corresponding to the first pixel in the video frame, and then, the terminal may calculate, by using a preset fusion algorithm, a fusion pixel value according to a pixel value of the first pixel and a pixel value of the second pixel. The terminal may generate a fused video frame composed of the calculated plurality of fused pixel values.
And 204, in the process of viewing and previewing, the terminal displays the fusion video on a viewing and previewing interface.
It should be noted that the terminal displays the fusion video in the view preview interface in real time, where "displaying the fusion video in real time" refers to: and at the moment k, the video frame in the fused video displayed on the viewing preview interface by the terminal corresponds to the video frame in the viewing video shot by the terminal at the moment k.
In other words, at the time k, the video frame in the fused video displayed by the terminal on the viewing preview interface is obtained by fusing the video frame in the viewing video shot by the terminal at the time k and the first image.
Referring to fig. 3, on the basis of the above-mentioned embodiment, the image processing method provided in the embodiment of the present application further includes the following steps:
In the viewing preview process, a user can observe the fusion video displayed in the viewing preview interface, in the observation process, if the user finds that the double exposure effect presented by the picture in the fusion video accords with the shooting expectation of the user, the user can trigger the shooting option, after the terminal detects the triggering operation of the shooting option, the terminal can generate and receive a shooting instruction, and the terminal can shoot to obtain a second image based on the shooting instruction.
It should be noted that the camera used by the terminal to capture the second image is the same camera as the camera that continuously captures the second image during the framing preview process.
And step 302, the terminal performs fusion processing on the first image and the second image to obtain a fused image with a double exposure effect.
After the second image is obtained through shooting, the terminal may perform fusion processing on the first image and the second image, so as to obtain a fusion image with a double exposure effect, where a technical process of performing fusion processing on the first image and the second image by the terminal is the same as a technical process of performing fusion processing on video frames in the first image and the viewfinder video by the terminal, and details of the embodiment of the present application are not repeated here.
In an optional embodiment of the present application, after the terminal acquires the first image, the terminal may perform compression processing on the first image to obtain a compressed image, and store the compressed image in the memory.
For example, as described above, the terminal may capture the first image after detecting that the capture option is triggered, in this embodiment of the application, optionally, the terminal may perform compression processing on the first image after capturing the first image to obtain a compressed image, and store the compressed image in the memory.
For another example, as described above, the terminal may obtain the first image from the local terminal after detecting the selection instruction for the first image based on the image selection interface, and after obtaining the first image, optionally, the terminal may perform compression processing on the first image to obtain a compressed image, and store the compressed image in the memory.
In addition, after the first image is captured, the terminal may store an original version of the first image (i.e., the uncompressed first image) in the magnetic disk.
Corresponding to the technical process described above:
in step 203, the terminal may obtain the compressed image from the memory, and perform fusion processing on the compressed image and each video frame in the viewfinder video.
In practical application, fusion processing generally involves a large amount of operations, the operation time delay is long, and the long operation time delay can cause that a terminal cannot timely perform fusion processing on video frames in a first image and a framing video, so that a fusion video is blocked in a framing preview interface.
In order to avoid video blocking, on one hand, the terminal can perform fusion processing on video frames in the compressed image and the viewfinder video, and the data volume of the compressed image is reduced compared with that of the first image, so that the calculation amount involved in the fusion processing by using the compressed image is reduced, the calculation time delay is also reduced, and the purpose of avoiding video blocking can be achieved; on the other hand, the terminal can acquire the compressed image from the memory, and the reading speed of the memory is far higher than that of the magnetic disk, so that the operation time delay can be further reduced by acquiring the compressed video from the memory, and the purpose of avoiding the video fusion blocking can be achieved.
It should be noted that, in order to further reduce the operation delay and avoid the video frame fusion, in step 203, the terminal may further perform compression processing on each video frame in the viewfinder video, and then the terminal may perform fusion processing on the compressed image and each video frame after the compression processing, respectively.
In step 302, the terminal may acquire the first image of the original version from the magnetic disk, and perform fusion processing on the acquired first image and the acquired second image.
In order to ensure the effect of fusing images, in the embodiment of the present application, the terminal may perform fusion processing on the first image and the second image in the original version.
In an optional embodiment of the present application, the viewing preview interface may include a first viewing preview frame and a second viewing preview frame, and the terminal may display the merged video in the first viewing preview frame and display the viewing video in the second viewing preview frame.
In practical application, a user has a requirement for previewing the fusion effect and a requirement for previewing the shooting effect of the second image, in order to meet the two requirements of the user, in the embodiment of the application, a first viewing preview frame and a second viewing preview frame can be respectively arranged in a viewing preview interface, wherein the terminal can display the fusion video in the first viewing preview frame and display the viewing video in the second viewing preview frame.
Optionally, the terminal may further set a preview frame enlargement option for each of the first view preview frame and the second view preview frame, and after detecting a trigger operation on the preview frame enlargement option of a certain view preview frame (the first view preview frame or the second view preview frame), the terminal may enlarge the certain view preview frame.
Optionally, the terminal may further set a preview frame closing option for each of the first view preview frame and the second view preview frame, and after detecting a trigger operation on the preview frame closing option of a certain view preview frame (the first view preview frame or the second view preview frame), the terminal may close the certain view preview frame.
In an optional embodiment of the application, the terminal may evaluate a double exposure effect of each video frame in the fusion video to obtain an evaluation result of each video frame in the fusion video, and then, the terminal may display the video frame of which the evaluation result satisfies a preset condition as a recommended image.
In order to assist the user in shooting, the terminal can evaluate the double exposure effect of each video frame in the fusion video, and recommend the video frame of which the evaluation result meets the preset condition to the user so as to prompt the user to shoot.
