Detailed Description

For the purposes of clarity, technical solutions and advantages of the present disclosure, the following further details the embodiments of the present disclosure with reference to the accompanying drawings.

The embodiment of the disclosure provides a method for locally amplifying an image, which can be implemented by a terminal with a display function, wherein the terminal can be a mobile phone, a tablet computer, a notebook computer, a desktop computer and the like, and a user can use various application programs based on different requirements during the use of the terminal, for example, the terminal can be provided with the application program for viewing the image. The image may be an image stored locally by the terminal. The image may also be an image obtained by the terminal from the server through an application program, for example, the application program may be a network game application program, and the image may be a game scene image obtained by the terminal from a background server of the network game application program.

As shown in fig. 1, the process flow of the method may include the following steps:

in step 101, the terminal acquires a first local area to be enlarged on the viewing image and an enlarged image corresponding to the viewing image.

The view image may be an image that has not undergone any enlargement processing, or may be an enlarged image.

The magnified image corresponding to the view image is an enlarged image based on the view image. Correspondingly, the magnified image can be an image after magnification, such as an image after magnification of a target multiple, on the basis of the image without any magnification treatment; the image after being amplified again, such as the image after being amplified again by the target multiple, may also be based on the image after being amplified. For convenience of description, the example may be given by taking the image that is not enlarged as the viewing image.

In some examples, the magnified image is another image that is the same as the display of the viewed image, but at a higher resolution. For example, the magnified image may be an image that is the same as the display content of the viewed image and is of equal size, but of higher resolution than the resolution of the viewed image; for another example, the enlarged image may be an image having the same display content as the viewing image, but a size larger than that of the viewing image and a resolution higher than that of the viewing image.

Therefore, the enlarged image may be an image obtained by enlarging the size of the view image, an image obtained by enlarging the resolution of the view image, or an image obtained by enlarging the size and the resolution of the view image. For convenience of description, the description and the related drawings may be illustrated with size enlargement, and the resolution enlargement is similar to the above, and will not be described in detail.

The magnified image may also be referred to as a clone image of the viewed image, because the display content in the viewed image and the magnified image are the same, and the size is different, or the resolution is different, or both the size and the resolution are different.

In one example, when a user intends to view a certain image (which may be noted as a view image), the view image may be acquired from the terminal locally or from a server and displayed on a display interface of the terminal. The first location on the display interface may be clicked on if the user intends to view a partial magnified view at a certain location on the display interface (which may be noted as the first location). When the terminal detects that the touch amplifying operation is triggered at the first position on the display interface, a first local area to be amplified on the checked image can be obtained based on the first position.

The first location may be a coordinate location of a click location of the user on the display interface, and the first local area is a local area in the view image determined according to the first location, and may be a circular area, a rectangular area, a polygonal area, or the like, which is exemplified by a circular area in this embodiment.

In an example, when the terminal detects that the touch zoom-in operation is triggered at the first position on the display interface, not only the first local area to be zoomed in on the view image, but also the zoomed-in image corresponding to the view image may be obtained. The terminal may acquire the first local area first, and then acquire the enlarged image corresponding to the view image, or may acquire the enlarged image corresponding to the view image first, and then acquire the first local area first, or may acquire the enlarged image and the first local area at the same time, where the order of acquiring the first local area and the enlarged image is not limited in this embodiment.

The magnified image may be an image that the terminal prestores, n being a number greater than 1 relative to the image that is magnified n times the view image. Alternatively, the magnified image is another image that is the same as the display content of the viewed image, but at a higher resolution.

In step 102, the terminal determines a second local area in the enlarged image corresponding to the first local area.

The second local area is a local area in the enlarged image, and the first local area and the second local area are different in size and size, but the image content in the areas is the same.

In one example, the terminal may determine a second partial region in the magnified image corresponding to the first partial region image based on a magnification of the magnified image relative to the viewed image and a position of the first partial region in the viewed image.

In step 103, the terminal overlays the second area image in the second local area on the first area image in the first local area to obtain a viewing image overlaid with the second area image.

In one example, after determining the second partial region in the magnified image, the terminal may overlay the second region image within the second partial region over the first region image within the first partial region, resulting in a viewing image overlaid with the second region image.

In step 104, the terminal displays a viewing image overlaid with the second area image.

In one example, after the terminal obtains the view image overlaid with the second area image, the view image overlaid with the second area image may be displayed. In this way, on the display interface of the terminal, the second area image may be displayed at the first partial area on the viewing image, while the other areas not covered by the second area image are still displayed with the same proportion of the image as the viewing image. Further, a local magnification of a local area of the view image can be achieved.

In one example, reference may be made to FIG. 2, where a in FIG. 2 represents a view image and a' represents an enlarged image corresponding to the view image. When the user intends to view the enlarged image of any partial area on the view image a, for example, when the user intends to view the enlarged image corresponding to the partial area a, the terminal may acquire the partial area a on the view image a, and the enlarged image a ' corresponding to the view image a and the partial area image a ' corresponding to the partial area image a on the enlarged image a '. Then, the terminal may overlay the partial area image a 'on the enlarged image a' on the viewing image a, and the partial area image a 'is overlaid on the partial area image a, resulting in the viewing image a overlaid with the partial area image a' shown on the right side of the arrow of fig. 2. Thereafter, as shown on the right side of the arrow with reference to fig. 2, a viewing image a overlaid with the partial area image a' may be displayed on the display interface of the terminal.

In one possible application scenario, as shown in fig. 3, after a user opens a view image, the user may click on the display interface at the location of the "mushroom" indicated by the arrow in fig. 3. The partial area where the "mushroom" is located as indicated by the arrow in fig. 4 may be enlarged on the display interface of the terminal, whereas the area image in the other area than the partial area where the "mushroom" is located in the view image in fig. 4 is not enlarged.

Therefore, when the user uses the method to amplify the local area of the image, the user can click any position on the view image on the display interface, and the terminal can locally amplify the local area clicked by the corresponding user in the view image according to the method, so that the flexibility of the user in viewing the locally amplified image can be improved.

As described above, when the terminal detects that the touch amplifying operation is triggered at the first position on the display interface, the first local area to be amplified on the view image may be acquired based on the first position. The process of acquiring the first local area by the terminal specifically from the first position may be as follows:

when the user clicks the first position on the display interface, the terminal can detect that the first position on the display interface triggers touch amplification operation, and the terminal can determine to view the second position corresponding to the first position on the image based on the first position on the display interface. While the second location may be farther from the edge line of the viewed image, the second location may also be closer to the edge line of the viewed image, in both cases, the manner in which the first local area is determined may be as follows:

If the second position is far from the edge line of the checked image, that is, if the distance between the second position and the edge line of the checked image is greater than or equal to the target value, determining a circular area which takes the second position as a center and takes the target value as a radius on the checked image as a first local area to be amplified on the checked image.

If the second position is closer to the edge line of the checked image, that is, if the distance between the second position and the edge line of the checked image is smaller than the target value, determining an area surrounded by the edge line of the checked image and an arc area which takes the second position as a center and takes the target value as a radius as a first local area to be amplified on the checked image.

The target value may be a value preset by a technician, or may be a value determined by the terminal according to the size of the checked image, for example, the target value may be a quarter of the short side length of the checked image.

In one example, as shown in fig. 5, where the second location is further from the edge line of the viewed image, the first localized area is a circular area as shown in fig. 5. As shown in fig. 6, the second position is closer to an edge line of the view image, and the first local area is an area surrounded by the edge line of the view image closer to the edge line and the arc-shaped area as shown in fig. 6. As shown in fig. 7, the second position is closer to both edge lines of the viewed image, and the first local area is an area surrounded by the two edge lines closer to the viewed image and the arc-shaped area as shown in fig. 7.

When the terminal detects that the touch amplifying operation is triggered at the first position on the display interface, the terminal can acquire not only the first local area on the checked image, but also the amplified image corresponding to the checked image.

In one example, the magnified image may be an image obtained by the terminal copying and re-listing pixels of the viewed image. For example, the terminal may copy and arrange pixels of the view image in advance based on the magnification ratio of the magnified image to the view image, and store data corresponding to the pixels of the view image after processing. Therefore, when the amplified image is acquired, the pixel points do not need to be copied and arranged, and time can be saved.

In one example, the magnified image may also be an image that a technician draws through drawing software in terms of the viewed image, both greater in size and resolution than the viewed image. For example, a technician may use drawing software to draw an enlarged image having a size greater than the size of the viewed image based on the magnification of the enlarged image relative to the viewed image, in accordance with the content of the image displayed by the viewed image. For example, the magnified image may be three times the magnification of the viewed image, and accordingly, a technician may draw a magnified image three times the size of the viewed image through drawing software.

Wherein, in order to further improve the definition of the magnified image so as to make the second region image within the second local region clearer, correspondingly, the resolution of the magnified image is higher than that of the viewed image. In this way, when a viewing image superimposed with the second area image is displayed, the displayed second area image is not only large in size but also high in sharpness.

The above is a process in which the terminal acquires the first partial area on the view image and the enlarged image corresponding to the view image, and after the terminal acquires the first partial area and the enlarged image, the terminal may determine the second partial area corresponding to the first partial area in the enlarged image based on the enlargement ratio of the enlarged image with respect to the view image. The specific method can be as follows:

first, the terminal may determine location information of a first center point of the first partial region in the viewing image. For example, referring again to fig. 2, the viewing image a is rectangular in shape, and the position information of the first center point of the first partial area a on the viewing image a may be noted as (α, β) with the upper left corner of the rectangle as the origin of coordinates.

Then, the terminal may determine the position information of the second center point corresponding to the first center point in the enlarged image based on the enlargement ratio of the enlarged image with respect to the viewing image and the position information of the first center point in the viewing image. For example, with reference to fig. 2 again, where the magnification ratio of the magnified image with respect to the viewed image is 3 times, still with the upper left corner of the magnified image as the origin of coordinates, the position where the positional information is (3α,3β) in the magnified image a 'may be determined as the second center point corresponding to the first center point of the first partial region a in the magnified image a'.

Finally, the terminal may determine, in the enlarged image, a second partial region having the same region shape as the first partial region with the second center point as the center point based on the position information of the second center point in the enlarged image, the enlargement ratio, and the region shape of the first partial region.

For example, referring again to fig. 2, the first partial region is a circular region having (α, β) as a center and r as a radius, and the second partial region is a circular region having (3α,3β) as a center and 3r as a radius. As another example, as shown in fig. 6 and 7, if the first partial region is a region surrounded by an arc-shaped region and an edge line of the viewed image, the second partial region is also a region surrounded by an arc-shaped region and an edge line of the enlarged image, wherein the size of the second partial region is three times the size of the first partial region.

The above is a procedure in which the terminal determines the first partial area located on the view image and the second partial area located on the enlarged image, and after the terminal determines the first partial area and the second partial area, the terminal can cover the second area image in the second partial area on the first area image in the first partial area to obtain the view image covered with the second area image. The specific flow can be as follows:

Wherein the terminal may obtain the view image covered with the second area image by a masking technique, i.e. a technique in which a partial area of the masked layer is displayed by the masking layer. The principle of masking technology is generally as follows:

the mask layer and the masked layer are two layers, the size of the mask layer is smaller than that of the masked layer, the transparency of the mask layer is larger than zero, and the transparency of the mask layer is larger than zero, namely the transparency of each pixel point of the mask layer is larger than zero. In application, the masking layer is overlaid over the masked layer, the image of the masking layer is not displayed, the image in the area overlaid by the masking layer on the masking layer may be displayed, and the image in the area not overlaid by the masking layer may not be displayed. By this principle, a mask layer having a size smaller than the magnified image and a transparency greater than zero can be overlaid on the magnified image. Further, the enlarged image may display an image in the region covered by the mask layer, and may not display an image in other regions.

The specific implementation process may be performed according to the process shown in fig. 8:

in step 1031, the terminal obtains a mask layer, the mask layer matches the second local area and the transparency of the mask layer is greater than zero.

In one example, the mask layer matches the second partial region, i.e., the size of the mask layer matches the size of the second partial region, and the shape of the mask layer matches the shape of the second partial region. For example, if the second partial region is a circular region, the mask layer may be the same circular region as the circular region; while if the second partial region is a region surrounded by an arc-shaped region and an edge line of the enlarged image, the mask layer may still be a circular region corresponding to the arc-shaped region. That is, the mask layer is a complete circular area, whether or not the second partial area is a complete circular area.

The implementation code for setting the mask layer to be circular may be: bg.2 mask=masksp.

The code of the above implementation is merely an example, and the embodiment is not specifically limited.

In step 1032, the terminal overlays the mask layer over the magnified image to obtain a second region image within the second local region.

In one example, after the terminal acquires the mask layer, the mask layer may be aligned to a second local area of the magnified image and overlaid on the magnified image, and a second area image within the second local area may be obtained according to principles of masking techniques. If the second partial region on the magnified image is a full circular region, the mask layer is over the second partial region of the magnified image with the circular edge of the mask layer aligned with the circular edge of the second partial region. If the second partial area on the enlarged image is an area surrounded by the arc-shaped area and the edge line of the enlarged image, the circular mask layer covers the second partial area on the enlarged image, and the circular edge of the mask layer is aligned with the circular edge of the arc-shaped area of the second partial area.

As can be seen from the above, the resulting second area image is a magnified image covered with a mask layer, wherein the mask layer is aligned with the second partial area of the magnified image.

In step 1033, the terminal overlays the second region image on the first region image of the first partial region, resulting in a viewing image overlaid with the second region image.

In one example, after the terminal overlays the second partial region with the mask layer over the magnified image, a second region image within the second partial region may be obtained, after which the second region image may be overlaid over the first region image within the first partial region over the viewing image, and further the viewing image overlaid with the second region image may be obtained.

Therefore, the checked image which is determined to be covered with the second area image is obtained by firstly aligning the acquired mask layer with the second local area of the enlarged image and covering the enlarged image to obtain a second area image of the second local area; the magnified image covered with the mask layer is then overlaid on the viewed image with the mask layer aligned with the first localized region of the viewed image. Since only the portion of the magnified image that is covered by the mask layer can be displayed and the mask layer does not affect the lowermost viewed image, a viewed image covered with the second area image can be obtained.

In one example, obtaining a viewed image overlaid with a second area image may also be performed in accordance with a flow as shown in fig. 9:

in step 1031', the terminal overlays the magnified image over the viewed image in such a way that the first localized area corresponds to the second localized area.

In one example, the terminal may align the second localized area with the first localized area, overlaying the magnified image over the viewed image. For example, if the first partial region and the second partial region are both circular regions, the center of the second partial region may be aligned with the center of the first partial region, overlaying the magnified image over the viewed image. For another example, if the first partial region and the second partial region are each a region including an arc-shaped region and an edge line, the terminal may align a center point of the arc-shaped region of the second partial region with a center of the arc-shaped region of the first partial region, align the edge line of the second partial region with the edge line of the first partial region, and then overlay the magnified image on the viewing image.

The implementation code for overlaying the magnified image subjected to triple magnification on the viewing image may be:

Let bg2＝new Sprite()；

Laya.stage.addChild(bg2)；

bg2.graphics.drawTexture(bgRes)；

bg2.scale(3,3).

In step 1032', the terminal obtains a mask layer that matches the second local region and has a transparency greater than zero.

Wherein, after the terminal overlays the magnified image on the viewing image, a pre-stored mask layer may be acquired. As mentioned above, the mask layer may be a circular area matching the second partial area, i.e. the circular area of the mask layer matches the circular area of the second partial area, or the circular area of the mask layer matches the arc-shaped area of the second partial area.

In step 1033', the terminal overlays the mask layer over the magnified image resulting in a viewed image overlaid with the second area image.

In one example, after the terminal overlays the magnified image over the viewed image, a mask layer may be overlaid at a second partial region of the magnified image resulting in a viewed image overlaid with a second region image.

It can be seen that the above-described procedure of determining a viewing image overlaid with a second partial region image is to overlay the magnified image over the viewing image first, wherein the second partial region is aligned with the first partial region; a masking layer is then overlaid on the magnified image, wherein the masking layer is aligned with the second localized region. Since only the portion of the magnified image that is covered by the mask layer can be displayed and the mask layer does not affect the lowermost viewed image, a viewed image covered with the second area image can be obtained.

Based on the above, the obtained viewing image covered with the second area image by the flow shown in fig. 8 and by the flow shown in fig. 9 may include three layers: a viewing image at the lowest layer, a magnified image overlaying the viewing image, and a mask layer overlaying the magnified image. Because the mask layer only generates a mask effect on the image layer below the mask layer, the image displayed on the display interface of the terminal is a view image covered with the second area image, and because the second area image is an area image in the enlarged image, the area, which is not covered by the second area image, of the view image is still an area image in the view image, and further, the local enlargement of the view image can be realized.

In one exemplary application, the user may also slide on the display interface, and the enlarged local area on the viewed image changes dynamically during the sliding process, so that the first local area to be enlarged on the viewed image remains consistent with the user's operating position on the display interface.

When the user slides on the display interface, the process of acquiring the first local area to be amplified on the view image by the terminal may be as follows:

When the terminal detects a sliding amplifying operation from a starting position to an ending position on the display interface, acquiring a first local area to be amplified on the checked image based on a first position, wherein the first position is a real-time sliding position between the starting position and the ending position on the display interface.

The first position is the starting position when the user starts to slide; the end position is a position where the user ends the slide on the display interface, and the first position is the end position when the user ends the slide.

The sliding of the user on the display interface may be sliding on the display interface by a finger or sliding on the display interface by a mouse, and the implementation manner of sliding on the display interface is not limited in this embodiment.

In one example, when the user performs a sliding zoom-in operation on the display interface, the terminal may detect a first position touched by the user on the display interface in real time and then determine to view a first partial region to be zoomed in on the image based on the detected first position. The manner in which the terminal determines the first local area based on the first location has been described above, and reference may be made to the above, which will not be described herein.

In one possible application, when the user slides to the B position during the sliding process on the display interface, the corresponding area of the B position on the magnified image is the B area image, and the viewing image covering the B area image may be displayed on the display interface according to the above method. When the user continues to slide from the B position to the C position, the corresponding area of the C position on the magnified image is the C area image, and a view image covering the C area image can be displayed on the display interface according to the method. In the process of sliding from the B position to the C position, the overlapping part of the B region image and the C region image is still in the amplifying effect, and the non-overlapping part of the B region image and the C region image can be switched to the same display scale as the viewing image, that is, to the effect before amplifying.

In this way, when the user performs the sliding zoom operation on the display interface, the area of the display interface that locally zooms in on the viewing image also changes dynamically, so that the area image of the zoomed-in image that is overlaid on the viewing image is consistent with the real-time sliding position of the user at the current operation position on the display interface.

When the terminal performs sliding amplifying operation by moving the amplified image and the mask layer, the local area to be amplified on the checked image is consistent with the current operation position of the user on the display interface, wherein the code for implementing the amplifying image and the mask layer movement can be as follows:

Laya.stage.on(Laya.Event.MOUSE_MOVE,10is,()＝>{

bg2.x＝-Laya.stage.mouseX*2；

bg2.y＝-Laya.stage.mouseY*2；

maskSp.x＝Laya.stage.mouseX；

maskSp.y＝Laya.stage.mouseY；}).

Based on the above, one scenario in which the method locally enlarges the view image may be that after a user opens a target application installed on the terminal, the target application may be searched for the view image to be viewed, and a zoom image of the view image may be displayed on a display interface of the terminal. After clicking the zoom image of the view image, the terminal can display the complete view image on the display interface through an image viewing tool of the target application program.

Alternatively, another possible scenario may be that after the user opens the target application, thumbnail images of multiple images may be displayed on the display interface of the terminal, when the user intends to view one of the images, the image that the user intends to view may be recorded as a view image, and the user may click on the thumbnail image corresponding to the view image. The terminal may then display the complete viewing image on the display interface through the image viewing tool of the target application.

As shown in the flowchart of fig. 10, after step S1, that is, after displaying the view image on the display interface of the terminal, the user may perform the operation of locally zooming in on the display interface. The user can directly perform local amplification operation on the display interface, or can perform local amplification operation after starting the local amplification function. For example, in the latter case, a function icon corresponding to the local zoom-in function is provided on the display interface on which the view image is displayed, and after the user clicks the function icon, the local zoom-in function may be turned on, and thereafter, the user may perform a local zoom-in operation on the display interface.

As shown in the flowchart of fig. 10, when the terminal detects that the touch zoom-in operation is triggered on the display interface, step S2 may be performed next to determine a first local area to be zoomed in on the view image, then steps S3 and S4 may be performed by the terminal to obtain a zoomed-in image corresponding to the view image, and determine a second local area corresponding to the first local area on the zoomed-in image, and then step S5 is performed by the terminal to obtain a mask layer adapted to the second local area.

In this embodiment, the sequence of the step S3 and the step S5 is not limited, and may be executed simultaneously, or the step S5 may be performed before the step S3.

Then, in step S6, the terminal may obtain a viewing image covered with a mask layer and a magnified image, wherein the mask layer is located on the magnified image and corresponds to the second partial region, the magnified image is located on the viewing image, and the first partial region corresponds to the second partial region. Further, according to the principle of the masking technique, in step S7, a view image covered with the second area image in the second partial area may be displayed on the display interface, that is, a view image having a partial enlargement effect may be displayed on the display interface.

And then, when the terminal detects that the sliding operation is triggered on the display interface, correspondingly, the first local area which needs to be enlarged on the checked image is updated, and then, the second local area which corresponds to the first local area on the enlarged image is also updated. In step S8, the terminal may implement updating of the second local area by moving the enlarged image and the mask layer according to the updating condition of the first local area, so that the viewing image may cover the updated area image in the second local area, and in step S9, the viewing image covered with the updated area image in the second local area may be displayed on the display interface.

Therefore, the process of locally amplifying the checked image by the user through the method is similar to that of the process of holding the magnifying glass by the user, and the visual effect of holding the magnifying glass to view the checked image can be achieved when the user views the regional image in the local region of the checked image.

Based on the above, one possible application scenario may be that the view image may be a game scenario image in a network game application program, and the user may perform local magnification processing on the game scenario image in the network game application program. For example, a plurality of application programs may be installed on a terminal of a user, where the application programs may include an online game application program, and as shown in fig. 11, a plurality of application program icons are displayed on a desktop of the terminal, and an application program icon clicked by the user is an application program icon corresponding to a certain online game application program.

After clicking an application icon corresponding to a certain network game application, the user enters a start interface of the network game application, as shown in fig. 12, and after clicking a start game button, the user can enter a mode selection interface of the game shown in fig. 13. Then, after the user selects a certain mode, the game interface shown in fig. 14 may be entered, where fig. 14 is a game scene image of a certain frame in the network game application. The user may click on any position on the game scene image to perform local amplification processing, for example, as shown in fig. 14, the position pointed by the finger of the user is the position where the user intends to perform local amplification. After the user clicks the position to be locally enlarged, the game scene image which is locally enlarged at the position clicked by the user as shown in fig. 15 may be displayed on the display interface of the terminal.

Here, the scene graphs of fig. 11 to 15 in which the partial enlargement processing is performed on the game scene image are merely an example, and are not particularly limited.

In the embodiment of the disclosure, when a user performs local amplification on any local area, such as a first local area, on a viewing image, the terminal may first acquire the first local area on the viewing image and an amplified image corresponding to the viewing image; then, a second partial region corresponding to the first partial region in the enlarged image may be determined; then, the second area image in the second local area can be overlaid on the first area image in the first local area, and a view image overlaid with the second area image can be obtained and displayed. Therefore, by using the method, any local area in the image can be enlarged, and the flexibility of viewing the locally enlarged image by a user can be improved.

The embodiment of the disclosure also provides a method for locally amplifying the image, which can be realized by the terminal with the display function. The method may include: when a terminal detects an operation of opening a target application program, opening the target application program; when the terminal detects an operation instruction for displaying a view image, displaying the view image through an image viewing tool of the target application program; and when detecting the enlargement operation triggered in the first local area on the view image, displaying the view image covered with a second area image, wherein the second area image is the image content in a second local area corresponding to the first local area in the enlarged image.

The target application is an application selected by a user installed on the terminal, for example, a media application installed on the terminal, a browsing application, and the like.

Wherein the image viewing tool may be a plug-in the target application for executing the display image.

In one example, the target application may be a browsing application, and accordingly, the user may double-click open the target application on an icon corresponding to the target application on the desktop of the terminal. After a user opens a target application program, the target application program can be searched for a to-be-viewed image, and a zoom image of the to-be-viewed image can be displayed on a display interface of the terminal. After clicking the zoom image of the view image, the terminal can display the complete view image on the display interface through an image viewing tool of the target application program. The user may then zoom in locally on the display interface displaying the viewed image, according to the method described above, for specific procedures, see the embodiments described above.

Alternatively, the target application may be a media application, and accordingly, the user may double-click open the target application on an icon corresponding to the target application on the desktop of the terminal. After the user opens the target application program, the thumbnail of the plurality of images can be displayed on the display interface of the terminal, when the user intends to view one of the images, the image which the user intends to view can be recorded as the view image, and the user can click the thumbnail corresponding to the view image. The terminal may then display the complete viewing image on the display interface through the image viewing tool of the target application. The user may then zoom in locally on the display interface displaying the viewed image, according to the method described above, for specific procedures, see the embodiments described above.
