Detailed Description

Technical solutions in the embodiments of the present application will be clearly described below with reference to the drawings in the embodiments of the present application, and it is apparent that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments obtained by a person of ordinary skill in the art based on the embodiments in the present application are within the scope of the protection of the present application.

The terms "first," "second," and the like in the description of the present application, are used for distinguishing between similar objects and not necessarily for describing a particular sequential or chronological order. It is to be understood that the terms so used are interchangeable under appropriate circumstances such that the embodiments of the application are capable of operation in sequences other than those illustrated or otherwise described herein, and that the objects identified by "first," "second," etc. are generally of a type and do not limit the number of objects, for example, the first object may be one or more. In addition, "and/or" in the specification means at least one of the connected objects, and the character "/", generally means a relationship in which the associated objects are one kind of "or".

The terms "at least one", and the like in the description of the present application refer to any one, any two, or a combination of two or more of the objects that it comprises. For example, at least one of a, b, c (item) may represent: "a", "b", "c", "a and b", "a and c", "b and c" and "a, b and c", wherein a, b, c may be single or plural. Similarly, the term "at least two" means two or more, and the meaning of the expression is similar to the term "at least one".

The image processing method, apparatus, electronic device, medium and computer program product provided in the embodiments of the present application are described in detail below with reference to the accompanying drawings by means of specific embodiments and application scenarios thereof.

The image processing method, the image processing device, the electronic equipment, the medium and the computer program product provided by the embodiment of the application can be applied to a scene for storing images in the electronic equipment.

With the development of electronic equipment shooting technology, the definition of a single image shot by the electronic equipment is higher and higher, and meanwhile, the corresponding occupied storage space is larger and larger, so that a great challenge is presented to the storage space of the electronic equipment.

Typically, a single image taken by an electronic device occupies a storage space that varies from 1-2MB to 7-8 MB. In daily use and travel photographing of a user, in order to ensure that the most satisfactory picture can be taken, it is common to repeat photographing a plurality of times in one scene and use it in a subsequent video clip or friend circle.

However, users often do not easily clean other photos, which causes that seven or eight photos in a same scene may appear, and occupy more storage space, which greatly consumes the storage space of the electronic device. Moreover, if the image is compressed and stored, the user needs to synchronously decompress and view the image when previewing, so that the effect of viewing the image by the user is affected and the problem of mobile phone endurance is caused by frequent decompression. As such, insufficient remaining storage space of the electronic device may result.

In the embodiment of the application, the storage space occupied by the same image content in the at least two images can be reduced, the storage space occupied by storing the at least two images is reduced, and the remaining storage space of the electronic equipment is further increased.

The execution subject of the image processing method provided in the embodiment of the present application may be an image processing apparatus. The image processing apparatus may be an electronic device or a component in the electronic device, such as an integrated circuit or a chip, for example. The image processing method provided in the embodiment of the present application will be exemplarily described below by taking an electronic device as an example.

An embodiment of the present application provides an image processing method, and fig. 1 shows a flowchart of the image processing method provided in the embodiment of the present application, where the method may be applied to an electronic device. As shown in fig. 1, the image processing method provided in the embodiment of the present application may include the following steps 101 and 102.

Step 101, the electronic device determines a common image layer from at least two images when the similarity of the at least two images is greater than or equal to a preset similarity.

In some embodiments of the present application, the at least two images may be images in an electronic device. It is understood that the image in the electronic device may include an image captured by the electronic device, an image obtained by the electronic device capturing the content displayed on the screen, an image received by the electronic device from another device, an image downloaded by the electronic device from a network, and an image in a video.

In some embodiments of the present application, the at least two images may belong to the same video or different videos.

In some embodiments of the present application, the same video or different videos to which the at least two images belong may be videos stored in the electronic device, or may be videos acquired by the electronic device from other devices. The embodiments of the present application are not particularly limited.

The at least two images may be at least two frames of images in a video stored in the electronic device, for example.

Thus, the electronic device can improve the flexibility of acquiring at least two images with the similarity greater than or equal to the preset similarity.

In some embodiments of the present application, the similarity of the at least two images being greater than or equal to a preset similarity may indicate: the image content similarity of the at least two images is greater than or equal to a preset similarity. In other words, at least part of the same image content exists in the at least two images, and the at least two images are similar images.

The at least two images may be multiple images captured by the electronic device in the same capture scene.

The at least two images may be, for example, a plurality of images acquired by the electronic device from other devices that contain at least partially identical image content.

In some embodiments of the present application, the preset similarity may be default to the electronic device or may be set by a user. The embodiments of the present application are not particularly limited.

In some embodiments of the present application, the electronic device may calculate, through an image intelligent comparison algorithm, a similarity between image contents of images stored by the electronic device, so as to determine at least two images with image content similarity greater than or equal to a preset similarity.

For example, the electronic device may calculate the similarity between the image contents of the images through a histogram algorithm, thereby determining at least two images having a similarity greater than or equal to a preset similarity.

The electronic device may also calculate a similarity between image contents of the images through a gray scale map algorithm, thereby determining at least two images having a similarity greater than or equal to a preset similarity.

In practical implementation, the electronic device may further calculate the similarity between the image contents of the images through any other image intelligent comparison algorithm, so as to determine at least two images with the similarity greater than or equal to the preset similarity. The embodiments of the present application are not particularly limited.

For example, the preset similarity is 50%. As shown in fig. 2, it is assumed that four images of an image 201, an image 202, an image 203, and an image 204 are stored in the electronic device. The electronic device may determine that the image 201, the image 202, and the image 203 each include the image content of sun, snow, and maple leaves by comparing the image content of the four images, where the image 201, the image 202, and the image 203 are images in the same shooting scene, and the image 204 is an image in another shooting scene. The intelligent image comparison algorithm of the electronic device determines that the similarity between the image 201, the image 202 and the image 203 is 60%. So that the electronic device can determine the image 201, the image 202, and the image 203 as three images having a similarity greater than or equal to a preset similarity. Meanwhile, the images 201 and 202 also comprise carts and figures at different positions; also included in the image 203 is a person without a cart.

In some embodiments of the present application, the electronic device may acquire at least two images in a preset scene, and calculate the similarity of the images in the electronic device.

For example, assuming that the above-mentioned preset scenario is that the electronic device is idle and has sufficient electric power, the electronic device may acquire at least two images with a similarity greater than or equal to the preset similarity under the condition that the electronic device is idle and has sufficient electric power.

It should be noted that, when the electronic device acquires the at least two images, the images with similar storage time may be preferentially compared, as shown in fig. 2, the storage time of the image 201 is 2023, 8, 23, and 13:23:11, the storage time of the image 202 is 2023, 8, 23, 13:23:21, the image 203 is stored for 2023, 9, 13, 15:33:31, the image 204 is stored for 2023, 8, 24, 15:23:11. the storage time of the image 201 and the storage time of the image 202 are similar, and the electronic device may preferentially classify the images to obtain at least two images with a similarity greater than or equal to a preset similarity. It can be understood that the calculation amount of the electronic equipment is moderate at this time, and the method is suitable for optimizing the storage space of the electronic equipment in real time.

For example, assuming that the above-mentioned preset scenario is when the electronic device is charged, the electronic device may perform traversal comparison on the image stored in the preset time period and all the images stored in the electronic device under the charging condition, so as to obtain at least two images with a similarity greater than or equal to the preset similarity.

It can be understood that the calculation amount of the electronic device is larger at this time, so that the storage space of the electronic device can be optimized to the maximum extent.

For example, assuming that the above-mentioned preset scene is an image stored in the electronic device, for example, when the electronic device shoots an image, the electronic device may perform traversal comparison on the image and all the images stored in the electronic device, so as to obtain at least two images with a similarity greater than or equal to the preset similarity.

It should be noted that, when the electronic device stores the image, the electronic device may also store the image separately first, and compare the image with other images stored in the electronic device in a preset scene later, so as to obtain at least two images with similarity greater than or equal to the preset similarity. The embodiments of the present application are not particularly limited.

In some embodiments of the present application, the common layer may include the same image content in the at least two images.

In some embodiments of the present application, after the electronic device determines the common image layer from at least two images, the non-common image layer corresponding to each image may also be determined from the at least two images.

It is understood that the non-common layer corresponding to each of the at least two images may include image contents of the at least two images other than the image contents of the common layer.

In some embodiments of the present application, for each of at least two images acquired by an electronic device, the electronic device may perform image layering on the at least two images, and extract the same image content in the at least two images by using an artificial intelligence (Artificial Intelligence, AI) algorithm, so as to separate a common image layer and at least two non-common image layers.

It will be appreciated that the content of the images in the common layer separated by each of the at least two images is the same. The content of the images in the non-shared image layer separated from each of the at least two images is different, and the non-shared image layer may be a private image layer of the corresponding image.

Illustratively, in conjunction with fig. 2, as shown in fig. 3, the electronic device may perform layering processing on the image 201 to obtain a shared layer 301 and a non-shared layer 302; layering the image 202 to obtain a shared image layer 301 and a non-shared image layer 303; the image 203 is layered to obtain a shared layer 301 and a non-shared layer 304. Wherein the common layer 301 comprises sun, snow and maple leaves; the non-common layer 302 includes characters and carts therein; the non-common layer 303 includes a person and a cart, and the positions of the person and the cart in the non-common layer 303 are different from those in the non-common layer 302; only characters are included in the non-common layer 304.

It will be appreciated that non-common layer 302 is a private layer of image 201, non-common layer 303 is a private layer of image 202, and non-common layer 304 is a private layer of image 203; common layer 301 is a common layer corresponding to image 201, image 202, and image 203.

In some embodiments of the present application, the electronic device may indicate the at least two images through the obtained at least two non-common image layers. That is, the common layer obtained by the electronic device may not be counted as a picture, and the presence of the common layer does not change the number of images stored in the electronic device.

Step 102, the electronic device stores at least two images according to the shared image layer and the non-shared image layer of the at least two images.

In some embodiments of the present application, the electronic device may store a determined common image layer in association with a non-common image layer in each of at least two images, so as to implement storage of the at least two images, so that other image contents in the images may be separated into private non-common image layers by extracting the same image contents contained in the at least two images into the common image layer. The shared image layer only needs to be stored, so that the consumption of the storage space is greatly reduced, and the remaining storage space of the electronic equipment can be increased while the long endurance of the storage space of the electronic equipment is realized.

For example, as shown in fig. 2, assume that four images, that is, an image 201, an image 202, an image 203, and an image 204, are stored in the electronic device, and that the image 201 occupies 5MB of storage space, the image 202 occupies 6MB of storage space, the image 203 occupies 4MB of storage space, and the image 204 occupies 7MB of storage space. I.e. the four images occupy a total of 22MB of memory, with 15MB of memory occupied by images 201, 202 and 203. Referring to fig. 2, as shown in fig. 3, the electronic device performs layering processing on an image 201, an image 202, and an image 203, and obtains a 3MB shared layer 301, a 2MB non-shared layer 302, a 3MB non-shared layer 303, and a 1MB non-shared layer 304. After the electronic device stores the obtained common layer 301, the non-common layer 302, the non-common layer 303 and the non-common layer 304 in an associated manner, the storage space occupied by the common layer 301, the non-common layer 302, the non-common layer 303 and the non-common layer 304 is 9MB, which greatly reduces the occupation of the storage space compared with 15MB occupied by the image 201, the image 202 and the image 203.

In some embodiments of the present application, the electronic device may store the at least two images by associating one common layer with a non-common layer in each image by adding the same identifier to the one common layer and the non-common layer in each image.

In some embodiments of the present application, the electronic device may further store the at least two images by creating a mapping table to associate the one common layer with the non-common layer in each image.

In a practical implementation, the electronic device may store the at least two images by associating a common image layer with a non-common image layer in each image in any other manner. The embodiments of the present application are not particularly limited.

In some embodiments of the present application, for image frames of a video stored in an electronic device, the electronic device may perform layer separation processing on at least two image frames of the video, obtain a common layer and at least two non-common layers corresponding to the at least two image frames, and store the at least two image frames in an associated manner. Thus, the electronic device can reduce the storage space required to store the video by reducing the repeated storage of the same image content as compared to the storage space required to store the video.

It will be appreciated that the video itself is made up of image frames, for example, one frame per frame, and that if the number of base frames required for smooth video playback is 20 frames, then there should be at least 20 images in this second. In some non-motion scenes in the video, most elements in a plurality of image frames in the scene are similar, so that the electronic device can perform intelligent image layer separation on the plurality of image frames to obtain a common image layer shared by the plurality of image frames and a plurality of proprietary non-common image layers.

In some embodiments of the present application, the electronic device may store the common layer shared by the plurality of image frames separately, while preserving the plurality of non-common layers private to the plurality of video image frames directly in the original video and identifying it as a layer that is not the original video frame.

According to the image processing method, the storage space occupied by the same image content in the at least two images can be reduced, the storage space occupied by storing the at least two images is reduced, and the remaining storage space of the electronic equipment is further increased.

In some embodiments of the present application, for each of at least two images, a non-common layer of images may be associated with image information.

In some embodiments of the present application, the image information may include at least one of: the identification of the shared layer, the storage position of the shared layer, the layer position of the shared layer, the offset information of the shared layer, the shooting time of the image, the shooting place of the image, the shooting parameter of the image and the image parameter of the image.

In some embodiments of the present application, the electronic device associating an identification of a common layer with a non-common layer of an image may indicate that the image is separated into the non-common layer and the common layer indicated by the identification. Therefore, the electronic equipment can quickly find the shared layer based on the identification of the shared layer when displaying or using the image, and the image is obtained based on the shared layer and the non-shared layer.

In some embodiments of the present application, after the electronic device obtains the shared image layer of at least two images and the non-shared image layer of each image of at least two images, the electronic device may add the same and unique identifier to the shared image layer and the non-shared image layer of each image, so that the electronic device may quickly find the shared image layer and the non-shared image layer required for displaying the image when displaying the image.

For example, for multiple images containing the same image content 1, the electronic device may add the identification 1 for one common layer corresponding to the multiple images containing the same image content 1 and for non-common layers in each image. For multiple images containing the same image content 2, the electronic device may add the identifier 2 for one common layer corresponding to the multiple images containing the same image content 2 and for non-common layers in each image.

In some embodiments of the present application, the above-described identification may include, but is not limited to: text labels, graphic combination labels, numbers, etc.

In some embodiments of the present application, the storage location of the common layer may indicate a storage address of the common layer in the electronic device.

In some embodiments of the present application, the layer position of the common layer may indicate a level of the common layer in the image. For example, the layer position of the common layer may indicate that the common layer is the bottom layer of the image, i.e. the layer position is 0.

Illustratively, the identification of the common layer includes a number, the layer position of the common layer is 0, and the layer position of the non-common layer is 1. As shown in fig. 3, after obtaining the common layer 301, the non-common layer 302, the non-common layer 303, and the non-common layer 3034, the electronic device may add the same number "#123" to the common layer 301, the non-common layer 302, the non-common layer 303, and the non-common layer 304, and set the level of the layer position indication of the common layer 301 to 0, and set the level of the layer position indication of the non-common layer 302, the non-common layer 303, and the non-common layer 304 to 1, as shown in fig. 4. Thus, the electronic device can quickly find and synthesize the obtained image based on the hierarchy and the number of the layers.

In some embodiments of the present application, the offset information of the common layer may be used to characterize a field of view offset between a non-common layer and a common layer of different images of the at least two images.

In some embodiments of the present application, the above-described field of view offset may represent: after the electronic device determines the common layer from the at least two images, non-common layers of different ones of the at least two images are offset from a field of view of the common layer.

It can be understood that there may be a fine shift in the field of view between multiple images obtained in the same shooting scene, for example, the electronic device shakes when shooting multiple images, or the electronic device adopts a wide-angle camera and a telephoto camera when shooting multiple images, and these fine shifts may cause that when the common image layer obtained by extracting multiple images and the multiple non-common image layers obtained by extracting multiple images are overlapped, different origin of coordinates are needed to be overlapped, so that the original image can be obtained.

For example, the electronic device superimposes the common layer with the center of the common layer as the origin of coordinates and the non-common layer to obtain an image. Referring to fig. 2, as shown in fig. 4, the electronic device may add coordinates (0,0.012) to the non-shared layer 302, so that when the electronic device overlaps the shared layer 301 and the non-shared layer 302, it is necessary to shift the center of the non-shared layer 302 to the right by a distance of 0.012 units, and then overlap the center of the shared layer 301 to obtain the image 201. The electronic device may add coordinates (0, 0) to the non-common layer 303, so as to indicate that when the electronic device superimposes the common layer 301 and the non-common layer 303, the electronic device directly superimposes the center of the non-common layer 303 with the center of the common layer aligned, so that the image 202 may be obtained. The electronic device may further add coordinates (0.001,0) to the non-shared layer 304, so that when the electronic device superimposes the shared layer 301 and the non-shared layer 304, the electronic device needs to shift the center of the non-shared layer 304 to the left by a distance of 0.001 units, and then superimpose the non-shared layer with the center of the shared layer in alignment, so as to obtain the image 203.

In some embodiments of the present application, the electronic device may store, in association with the common image layer, a field of view offset between the common image layer and the non-common image layer of the first image, so when the electronic device displays the image, the common image layer and the non-common image layer may be directly superimposed based on the field of view offset to display the image, so as to ensure that the displayed image is consistent with the original image.

In some embodiments of the present application, the electronic device may acquire the capturing time of the image through a clock of the electronic device, and may also acquire the capturing time of the image through acquiring the network time. In practical implementation, the electronic device may also acquire the shooting time of the image in any other way. The embodiments of the present application are not particularly limited.

In some embodiments of the present application, the electronic device may acquire the shooting location of the image through a self-contained positioning system. In practical implementation, the electronic device may also acquire the shooting location of the image through any other way. The embodiments of the present application are not particularly limited.

Illustratively, in connection with fig. 2, as shown in fig. 3, since the image 201, the image 202, and the image 203 are hierarchically processed into the non-shared layer 302, the non-shared layer 303, the non-shared layer 304, and the shared layer 301, the electronic device can store the image information originally stored in the image 201, the image 202, and the image 203 in the non-shared layer 302, the non-shared layer 303, and the non-shared layer 304, respectively. For example, the electronic device may store information such as the shooting time, the longitude and latitude of the shooting location, and the like of the image 201 in the non-common layer 302.

In some embodiments of the present application, the shooting parameters of the image may include, but are not limited to: aperture, color temperature, white balance, depth of field, sensitivity, shutter speed, exposure compensation, focal length of the photographed image.

The image parameters of the image in some embodiments of the present application may include, but are not limited to: resolution, brightness, contrast, saturation, color, noise of the image.

In this way, various image information of the image can be associated with the non-shared image layer of the image, so that when the image is stored in the shared image layer and the non-shared image layer, the image information of the image can be reserved while the memory occupied by the stored image is reduced.

In some embodiments of the present application, the step 102 may include a step 102a described below.

Step 102a, the electronic device deletes at least two images, and stores at least two images according to the shared layer and the non-shared layer of the at least two images.

In some embodiments of the present application, after obtaining at least two images with a similarity greater than or equal to a preset similarity, the electronic device may determine a common image layer and an unshared image layer of each of the at least two images, delete the at least two images, and store one common image layer in association with the unshared image layer in each image.

In this way, the electronic device can replace the at least two images with one shared image layer and store the non-shared image layer in each image, so that the storage space occupied by the same image content in the at least two images can be reduced.

In some embodiments of the present application, the number of the at least two images is M.

In some embodiments of the present application, the image processing method provided in the embodiments of the present application may further include step 103 described below.

Step 103, the electronic device reserves a shared layer when detecting a deleting instruction of N images in at least two images and N is less than M.

Wherein M is a positive integer greater than or equal to 2, and N is a positive integer.

In some embodiments of the present application, after the electronic device deletes the at least two images and stores one common image layer in association with a non-common image layer in each image, if a user performs a delete operation on one or more images in the at least two images, the electronic device may delete only the non-common image layer of the one or more images, but not the common image layer.

In some embodiments of the present application, when only one non-shared layer is left in N non-shared layers corresponding to the at least two images, the electronic device may directly superimpose the non-shared layer with the shared layer to obtain an image corresponding to the one non-shared layer, and directly store the image. It will be appreciated that if the image is deleted, both the non-common layer and the common layer will be deleted.

In this way, since the electronic device can replace N images in the album with one shared image layer and store the non-shared image layer in each image, when deleting an image, only the non-shared image layer of the image can be deleted. Therefore, the storage space occupied by storing the N images can be reduced, and the storage of other images is not influenced, so that the residual storage space of the electronic equipment can be increased.

In some embodiments of the present application, the image processing method provided in the embodiments of the present application may further include step 104 described below.

Step 104, the electronic device displays the image according to the shared image layer and the non-shared image layer of the image for each of the at least two images.

In some embodiments of the present application, the electronic device may superimpose the common image layer of the image and the non-common image layer of the at least one image respectively to obtain the image to be displayed. It will be appreciated that the image obtained by stacking the common layer and the non-common layer is identical to the image content and the image quality of the original image before the layering process.

For example, in conjunction with fig. 2, as shown in fig. 5, the electronic device may superimpose the common layer 301 and the non-common layer 302, merge the sun, snow, and maple leaves in the common layer 301 and the characters and carts in the non-common layer 302 into the same image, and obtain and display the image 201.

It will be appreciated that when the user performs a search preview on an image, the user will not see the shared layer and the non-shared layer that only contain part of the image content, and the electronic device will display the complete image obtained by stacking the shared layer and the non-shared layer of the image.

In some embodiments of the present application, when the at least two images are image frames in the video, the electronic device may pre-process a non-shared image layer of several image frames when the electronic device plays the video, and superimpose the shared image layer and the non-shared image layer to form an original video image frame, so that an original playing effect may be achieved when the video is played.

Therefore, the electronic equipment displays at least one image with the same display effect and image quality as the original image based on the stored shared image layer and the non-shared image layer of the at least one image, so that the display effect and the image quality of the image can be ensured while the storage space occupied by the image is reduced.

In some embodiments of the present application, for each of the at least two images, the non-common layers of the image are associated with a layer position of the common layer.

In some embodiments of the present application, before the step 104, the image processing method provided in the embodiments of the present application may further include a step 105 described below; the step 104 may include a step 104a described below.

Step 105, the electronic device receives a first input for adjusting a layer position of a common layer.

Step 104a, the electronic device displays the image according to the non-common layer and the adjusted common layer of the image in response to the first input.

In some embodiments of the present application, a user may adjust a layer position of a common layer, so that the electronic device may obtain and display an image that is not exactly the same as an original image based on a non-common layer of the image and the adjusted common layer, and generate a personalized image copy.

In some embodiments of the present application, the first input may be used to adjust a layer position of the common layer. In other words, the first input may be an adjustment input of a layer position of the common layer.

In some embodiments of the present application, the first input includes, but is not limited to: the user inputs the touch control of the layer position of the shared layer through a touch control device such as a finger or a stylus, or inputs a voice command input by the user, or inputs a specific gesture input by the user, or inputs other feasibility, and the specific touch control can be determined according to actual use requirements. The specific gesture in the embodiment of the present application may be any one of a single-click gesture, a sliding gesture, a dragging gesture, a pressure recognition gesture, a long-press gesture, an area change gesture, a double-press gesture, and a double-click gesture; the click input in the embodiment of the application may be single click input, double click input, or any number of click inputs, and may also be long press input or short press input.

The first input may be a user setting input for a layer position of the common layer, so that the electronic device may display the image according to the non-common layer and the adjusted common layer of the image in response to the setting input.

The first input may also be voice input by the user, for example, "set the layer position of the common layer to 1", so that the electronic device may display the image according to the non-common layer and the adjusted common layer of the image in response to the voice input.

Illustratively, the first input is exemplified as a user setting input of a layer position of the common layer. Referring to fig. 2 and fig. 4, as shown in fig. 5, the electronic device may superimpose a non-shared layer 302 with a layer level of 1 indicated by the layer position and a shared layer 301 with a layer level of 0 indicated by the layer position, so as to obtain an image 201 with the shared layer 301 as a background and the non-shared layer 302 as a foreground. The electronic device may receive a setting input from a user to set a layer position of the common layer 301 from 0 to 2, and superimpose the non-common layer 302 with a layer level of 1 indicated by the layer position and the common layer 301 with a layer level of 2 indicated by the layer position, to obtain a copy of the image 201 with the common layer 301 as a foreground and the non-common layer 302 as a background.

Therefore, the image with personalized effect can be obtained based on the adjusted shared image layer and the non-shared image layer by adjusting the image layer position of the shared image layer, so that the flexibility of storing the image of the electronic equipment is improved.

In some embodiments of the present application, for each of at least two images, the non-common layers of the images are associated with image parameters of the common layer.

In some embodiments of the present application, before the step 104, the image processing method provided in the embodiments of the present application may further include a step 106 described below; the step 104 may include a step 104b described below.

Step 106, the electronic device receives a second input for adjusting image parameters of the common layer.

Step 104b, the electronic device displays the image according to the non-common layer and the adjusted common layer of the image in response to the second input.

In some embodiments of the present application, a user may adjust image parameters of a common image layer, so that the electronic device may obtain and display an image that is not exactly the same as an original image based on a non-common image layer of the image and the adjusted common image layer, and generate a personalized image copy.

In some embodiments of the present application, the second input may be used to adjust an image parameter of the common layer. In other words, the second input may be an adjustment input of an image parameter of the common layer.

In some embodiments of the present application, the second input includes, but is not limited to: the touch input of the image parameters of the shared image layer by the user through the touch device such as a finger or a stylus, or the voice command input by the user, or the specific gesture input by the user, or other feasibility inputs can be specifically determined according to the actual use requirement, and the embodiment of the application is not limited. The specific gesture in the embodiment of the present application may be any one of a single-click gesture, a sliding gesture, a dragging gesture, a pressure recognition gesture, a long-press gesture, an area change gesture, a double-press gesture, and a double-click gesture; the click input in the embodiment of the application may be single click input, double click input, or any number of click inputs, and may also be long press input or short press input.

The second input may be, for example, a user setting input of an image parameter of the common layer, so that the electronic device may display the image according to the non-common layer and the adjusted common layer of the image in response to the setting input.

The second input may also be voice input by the user, such as "adjust the contrast of the image parameter of the common layer to 50", so that the electronic device may display the image according to the non-common layer and the adjusted common layer of the image in response to the voice input.

Illustratively, the second input is exemplified as a user setting input for saturation of the common layer. The electronic device may receive a setting input from a user that sets the saturation of the common layer from 30 to 45, and superimpose the non-common layer 1 and the common layer of the image to obtain a copy of the image with greater saturation.

Therefore, the image with personalized effect can be obtained based on the adjusted shared image layer and the adjusted non-shared image layer by adjusting the image parameters of the shared image layer, so that the flexibility of storing the image of the electronic equipment is improved.

The above method embodiments, or various possible implementation manners in the method embodiments, may be executed separately, or may be executed in any two or more combinations, which may be specifically determined according to actual use requirements, and this embodiment of the application is not limited.

Step 202, the electronic device determines a common layer from at least two images, and identifies layer positions and coordinates of the common layer and non-common layer of the images.

Step 203, the electronic device stores a shared layer in association with a non-shared layer in each image, and adds the same identifier for the shared layer and each non-shared layer.

And 204, the electronic equipment superimposes the stored shared image layer and the stored non-shared image layer to display images.

Step 205, the electronic device receives and responds to the input of deleting the image by the user, and deletes the non-shared image layer of the image.

And simultaneously, the common image layer and the private non-common image layer are subjected to superposition preview in the subsequent preview process, so that the original image is displayed or exported. Meanwhile, due to the existence of the pre-classification behavior, a user can view images divided into the same scene when previewing the images, display the similarity with the previewed images on the device, and the user can easily identify repeated images through similarity comparison so as to further perform deletion operation.
