Description

Screen capturing method, screen capturing device, electronic apparatus, and computer-readable storage medium

Technical Field

The present disclosure relates to the field of computer technology, and more particularly, to a screen capturing method, a screen capturing apparatus, an electronic device, and a computer readable storage medium.

Background

Today, mobile phones support long shots, which are preferred by more people to share some information. The long screenshot is formed by splicing a piece Zhang Jietu, but if a dynamic image (for example, video, gif, etc.) is encountered in the screenshot process, the dynamic image is just at the splicing position of the upper screenshot and the lower screenshot, and when the long screenshot is spliced, the whole dynamic image is split into two parts and is intercepted twice. Because the dynamic diagram is always changing, the interception time of two parts of the dynamic diagram is different, and the intercepted contents are different, so that the two inconsistent screenshot splicing of the two contents is caused when the two parts are spliced, the generated long screenshot is disordered, and the generated long screenshot is not a complete spliced image.

Detailed Description

In order to enable those skilled in the art to better understand the technical solutions of the present disclosure, the technical solutions of the embodiments of the present disclosure will be clearly and completely described below with reference to the accompanying drawings.

It should be noted that the terms "first," "second," and the like in the description and claims of the present disclosure and in the foregoing figures 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 data so used may be interchanged where appropriate such that the embodiments of the disclosure described herein may be capable of operation in sequences other than those illustrated or described herein. The embodiments described in the examples below are not representative of all embodiments consistent with the present disclosure. Rather, they are merely examples of apparatus and methods consistent with some aspects of the present disclosure as detailed in the accompanying claims.

It should be noted that, in this disclosure, "at least one of the items" refers to a case where three types of juxtaposition including "any one of the items", "a combination of any of the items", "an entirety of the items" are included. For example, "including at least one of a and B" includes three cases side by side as follows: (1) comprises A; (2) comprising B; (3) includes A and B. For example, "at least one of the first and second steps is executed", that is, three cases are juxtaposed as follows: (1) performing step one; (2) executing the second step; (3) executing the first step and the second step.

Currently, when a long screenshot is obtained, if a dynamic region appears in the screenshot process, there is no method for identifying the dynamic region, so as to splice multiple shots based on the position of the dynamic region. Fig. 1 is a diagram showing that a long screen shot image is obtained by stitching a first screen shot image and a second screen shot image. As shown in fig. 1 (a) and (b), since the first screen capturing image and the second screen capturing image include two portions of one dynamic image, the time of acquiring the first screen capturing image is before or after the time of acquiring the second screen capturing image, and thus the two portions of the dynamic image may belong to different image contents of the dynamic image, so that the resulting long screen capturing image has a disorder of the image contents at the splicing position (as shown in fig. 1 (c)).

In order to solve the above-mentioned problems, the present disclosure provides a screen capturing method and a screen capturing device, which can identify a dynamic region when a part of the dynamic region exists at the bottom of a first screen capturing image, and determine the height of screen scrolling according to the information of the dynamic region, so that a second screen capturing image contains a complete moving picture, and then clip and splice the first screen capturing image and the second screen capturing image, so that a perfect long screen capturing can be synthesized.

A screen capturing method and a screen capturing apparatus according to example embodiments of the present disclosure will be described in detail below with reference to fig. 2 to 13.

Fig. 2 is a flowchart illustrating a method of obtaining a long screen shot image according to an example embodiment of the present disclosure.

According to example embodiments of the present disclosure, after the long graph intercept function is initiated, a first screen shot image of a page may be acquired at step S210. The first screen capture image of the page may be the entire screen, or a portion of the screen (e.g., the user may set the capture area of the screen as desired). In the following, by way of example only, the first screen capture image of a page is the entire screen.

In step S220, in case that a part of the dynamic area exists at the bottom of the first screen shot image, the scroll height may be determined based on the area information of the dynamic area.

According to an exemplary embodiment of the present disclosure, after the first screen shot image is acquired, it may be determined whether a portion of the dynamic region exists at the bottom of the first screen shot image. If there is no portion of the dynamic region at the bottom of the first screenshot, the page may be scrolled and a second screenshot of the page may be acquired and the first and second screenshots stitched according to conventional methods. If a part of the dynamic area exists at the bottom of the first screen shot image, the second screen shot image can be made to comprise the complete dynamic area, the part of the dynamic area of the first screen shot image is removed when the second screen shot image is spliced, and the complete dynamic area in the second screen shot image is reserved, so that a complete long screenshot is synthesized. The process of determining whether a portion of the dynamic region exists at the bottom of the first screen shot image will be described in detail below in connection with fig. 3.

Fig. 3 is a diagram illustrating a determination of whether there is a portion of a dynamic region at the bottom of a first screen shot image according to an example embodiment of the present disclosure.

First, area information of a dynamic area may be acquired. By way of example only, application (app) layer information (such as application package name, layer name, etc.) displayed at the top layer on the current screen may be obtained by the Android system, and region information (e.g., coordinates, size, etc.) of the dynamic region being changed on the layer may be obtained by Android SurfaceFlinger. The region information may be expressed as a plurality of Rect [ ], rect0[ X0, Y0, X1, Y1], rect1[ ], where Rect is empty may indicate that the current screen is unchanged, i.e., there is no dynamic region, rect0[ X0, Y0, X1, Y1] may indicate the upper leftmost angular coordinate (X0, Y0) and the lower rightmost angular coordinate (X1, Y1) of the dynamic region, or may indicate the upper rightmost angular coordinate (X0, Y0) and the lower leftmost angular coordinate (X1, Y1) of the dynamic region. There may be multiple dynamic regions in the first screen shot image, and multiple non-empty arrays Rect may be obtained.

Since the screen displayed interface is a tree structure constructed of various components, all User Interface (UI) layout information of the current displayed interface can be obtained through android uiautomator, and these information record all display controls of the current interface, including content descriptions displayed by the components and sizes, coordinates, etc. of the region.

After the UI layout information is obtained, bottom position information of the first screen shot image (for example, the bottommost coordinates of the scrollable content of the current screen, such as the coordinates of the point at the leftmost lower corner thereof, but not limited thereto, may be, for example, the coordinates of any point on the bottommost line thereof) may be calculated. Specifically, the bottommost coordinates S (x, y) may be calculated from the obtained UI layout information and screen resolution. If there is no bottom preset area (e.g., an application internal navigation bar and a system navigation bar), the bottommost coordinates S (x, y) are bottom position information of the first screen shot image. If the screen interface has a system navigation bar without applying an internal navigation bar (as in the right-hand diagram of fig. 3), the bottommost coordinates S' (x, y) can be obtained as the bottom position information of the first screen shot image according to the position of the system navigation bar.

It may be determined whether a portion of the dynamic region exists at the bottom of the first screen shot image based on the region information of the dynamic region and the bottom position information of the first screen shot image. For example, it may be determined whether the above calculated bottommost coordinates S (x, y) or S' (x, y) overlap with the region information Rect [ ] (excluding the upper and lower boundaries of the dynamic region) of the dynamic region, and if so, it is determined that a portion of the dynamic region exists at the bottom of the first screen shot image, and otherwise, it is determined that a portion of the dynamic region does not exist at the bottom of the first screen shot image.

According to an exemplary embodiment of the present disclosure, a height H of a portion of the dynamic region in the first screen capture image (e.g., H may be an absolute value of a difference between an upper left-corner ordinate Y0 of the dynamic region and Y of the bottom position information of the first screen capture image) may be determined based on region information of the dynamic region (e.g., rect0[ X0, Y0, X1, Y1 ]) and bottom position information of the first screen capture image (e.g., bottommost coordinates S (X, Y) or S' (X, Y) as described above), and a scroll height G may be determined based on a difference between the screen height H and the height H of the portion of the dynamic region. That is, the determined scroll height needs to ensure that the complete dynamic region can be presented in the second screenshot image of the page (i.e., G.ltoreq.H-H). For example, the difference between the screen height and the height of the portion of the dynamic region may be determined as the scroll height (i.e., g=h-H).

In step S230, the page may be scrolled and a second screenshot of the page may be acquired based on the determined scroll height.

In step S240, a long screen shot image may be obtained by stitching the first screen shot image and the second screen shot image. For example, when the scroll height is H-H, a long screen shot image may be acquired by removing a bottom region of the first screen shot image having a height of H (i.e., the partial dynamic region) and stitching the removed first screen shot image and second screen shot image.

A process of obtaining a long screen shot image by stitching the first screen shot image and the second screen shot image will be described below with reference to fig. 4 to 11.

Fig. 4 is a diagram illustrating stitching of a first screen capture image and a second screen capture image to obtain a long screen capture image according to a first example embodiment of the present disclosure.

In the case where a part of the dynamic area exists at the bottom of the first screen shot image as shown in fig. 4 (a), a difference between the screen height and the height of the part of the dynamic area may be determined as a scroll height, and based on the determined scroll height H-H, the page is scrolled and a second screen shot image is acquired (as shown in fig. 4 (b)).

A long screen shot image may be obtained by removing a bottom region having a height that is the difference between the screen height H and the determined scroll height G from the first screen shot image (i.e., removing the portion of the dynamic region from the first screen shot image), and stitching the removed first screen shot image and second screen shot image (as shown in (c) of fig. 4).

Fig. 5 is a diagram illustrating stitching of a first screenshot image and a second screenshot image to obtain a long screenshot image according to a second example embodiment of the present disclosure.

As shown in fig. 5 (a), in the case where a part of the dynamic region exists at the bottom of the first screen shot image, a value obtained by subtracting a preset height hx from a difference between the screen height and the height of the part of the dynamic region may be determined as a scroll height (g=h-H-hx), and based on the determined scroll height, the page is scrolled and a second screen shot image is acquired (as shown in fig. 5 (b)). As shown in fig. 5 (a) and (b), the region of height hx may be a non-dynamic region, or may contain all but not a portion of the other dynamic region.

Similar to the stitching method described with reference to fig. 4, a long screen shot image may be obtained by removing a bottom region having a height that is a difference between the screen height H and the determined scroll height G from the first screen shot image (i.e., removing the partial dynamic region and a region having a height hx immediately above the partial dynamic region from the first screen shot image), and stitching the removed first screen shot image and second screen shot image (as shown in (c) of fig. 5).

However, when the actual scroll height is less than the determined scroll height (e.g., when the page has been scrolled to the bottommost portion during scrolling of the page and cannot continue scrolling to the determined scroll height, or when the user manually scrolls the page such that the actual scroll height is less than the determined scroll height), the step of stitching the removed first and second screenshot images described with reference to fig. 4 or 5 may include: and removing a top area with the height being the difference between the determined scrolling height and the actual scrolling height from the second screen capture image, and stitching the removed first screen capture image and the removed second screen capture image to obtain a long screen capture image.

Further, the method of stitching the first screen shot image and the second screen shot image to obtain a long screen shot image described with reference to fig. 5 is not limited thereto, and for example, a long screen shot image may also be obtained by the following method of finding a contrast region: taking a region with the height of the preset height hx at the top of the second screen capturing image as a comparison region; searching the region of the first screen capturing image, which is the same as the contrast region, upwards from the upper part of the dynamic region of the first screen capturing image; removing the found region and the portion of the dynamic region from the first screen shot image; and splicing the removed first screen capturing image and the second screen capturing image to obtain a long screen capturing image. Here, the region at the top of the second screen shot image having the height of the preset height hx cannot include other dynamic regions or a part thereof, and when the region at the height of the preset height hx includes other dynamic regions or a part thereof, the hx size may be appropriately modified, for example, the hx may be reduced such that the region at the preset height hx does not include other dynamic regions or a part thereof. Further, similarly, when the actual scroll height is smaller than the determined scroll height, the step of stitching the removed first screen capture image and the removed second screen capture image to obtain a long screen capture image may include: removing a top region from the second screen capture image having a height that is the difference between the determined scroll height and the actual scroll height; and stitching the removed first screen capture image and the removed second screen capture image to obtain a long screen capture image.

According to example embodiments of the present disclosure, the application screen may include at least one preset area (e.g., an area that is not scrollable), that is, the first screen capture image and the second screen capture image may include at least one preset area. The at least one preset region may include, for example, but not limited to, a top preset region Ht, a bottom preset region Hb, or both the top preset region and the bottom preset region (Ht and Hb). Further, the top preset area and the bottom preset area may be one or more, and are described herein using one top preset area and/or one bottom preset area by way of example only. In the case where the first screen capture image and the second screen capture image include at least one preset region, the step of determining the scroll height based on a difference between the screen height and the height of the portion of the dynamic region may include: the scroll height is determined based on a value obtained by subtracting the height of at least one preset area from the screen height and subtracting the height of the part of the dynamic area. A method of obtaining a long screen shot image by stitching the first screen shot image and the second screen shot image in a case where the first screen shot image and the second screen shot image include at least one preset area is described below with reference to fig. 6 to 11.

Fig. 6 and 7 are diagrams illustrating a method of obtaining a long screen shot image by stitching a first screen shot image and a second screen shot image in a case where at least one preset area includes a top preset area according to a third exemplary embodiment of the present disclosure.

As shown in fig. 6, in the case where at least one preset area includes a top preset area (e.g., an a area having a height of Ht in fig. 6), the scroll height G may be determined as H-Ht. At this time, the step of obtaining the long screen shot image by stitching the first screen shot image and the second screen shot image may include: removing a bottom region having a height that is a value obtained by subtracting the determined scroll height from the screen height and subtracting the top preset region height from the first screen shot image (i.e., removing a bottom dynamic region having a height h from the first screen shot image); removing the top preset region from the second screen shot image; and stitching the removed first screenshot image and the removed second screenshot image to obtain a long screenshot image (as shown in fig. 6 (c)).

As shown in FIG. 7, the roll height G may be determined as H-H-hx-Ht. Similar to the steps described with reference to fig. 6, the step of obtaining a long screen shot image by stitching the first screen shot image and the second screen shot image may include: removing a bottom region having a height that is a value obtained by subtracting the determined scroll height from the screen height and subtracting the top preset region height from the first screen shot image (i.e., removing a bottom region having a height h+hx from the first screen shot image); removing the top preset region from the second screen shot image; and stitching the removed first screenshot image and the removed second screenshot image to obtain a long screenshot image (as shown in fig. 7 (c)).

In addition, when the scrolling height is H-hx-Ht, the first screen capturing image and the second screen capturing image may be spliced to obtain a long screen capturing image by the method of searching the contrast area as described above, which will not be described herein.

Further, when the actual scroll height is smaller than the determined scroll height, the step of stitching the removed first screen shot image and the removed second screen shot image, described with reference to fig. 6 and 7, to obtain a long screen shot image may include: removing a region having a height immediately below the top preset region from the removed second screen shot image as a difference between the determined scroll height and the actual scroll height; and stitching the removed first screen capture image and the removed second screen capture image to obtain a long screen capture image.

Fig. 8 and 9 are diagrams illustrating a method of obtaining a long screen shot image by stitching a first screen shot image and a second screen shot image in a case where at least one preset area includes a bottom preset area according to a fourth exemplary embodiment of the present disclosure.

As shown in fig. 8, in the case where at least one preset area includes a bottom preset area (e.g., the B area having a height Hb in fig. 8), the scroll height G may be determined as H-Hb. At this time, the step of obtaining the long screen shot image by stitching the first screen shot image and the second screen shot image may include: removing a bottom region having a height that is the difference between the screen height and the determined scroll height from the first screen capture image (i.e., removing the portion of the dynamic region and the bottom preset region from the first screen capture image); and splicing the removed first screen capturing image and the second screen capturing image to obtain a long screen capturing image.

As shown in fig. 9, in the case where at least one preset area includes a bottom preset area (e.g., the B area having a height Hb in fig. 9), the scroll height G may be determined as H-hx-Hb. Similar to the steps described with reference to fig. 8, the step of obtaining a long screen shot image by stitching the first screen shot image and the second screen shot image may include: the bottom region having a height of the difference between the screen height and the determined scroll height is removed from the first screen shot image (i.e., the region having a height hx immediately above the partial dynamic region, and the bottom preset region are removed from the first screen shot image), and the removed first screen shot image and second screen shot image are stitched to obtain a long screen shot image.

In addition, when the scrolling height is H-hx-Hb, the first screen capturing image and the second screen capturing image may be spliced to obtain a long screen capturing image by the method of searching the contrast area as described above, which will not be described herein.

Further, when the actual scroll height is smaller than the determined scroll height, the step of stitching the removed first and second screen shots, described with reference to fig. 8 and 9, to obtain a long screen shot may include: and removing a top area with the height being the difference between the determined scrolling height and the actual scrolling height from the second screen capture image, and stitching the removed first screen capture image and the removed second screen capture image to obtain a long screen capture image.

Fig. 10 and 11 are diagrams illustrating a method of obtaining a long screen shot image by stitching a first screen shot image and a second screen shot image in a case where at least one preset area includes a top preset area and a bottom preset area according to a fifth exemplary embodiment of the present disclosure.

As shown in fig. 10, in case that at least one preset area includes a top preset area and a bottom preset area, the roll height G may be determined as H-Hb-Ht. At this time, the step of obtaining the long screen shot image by stitching the first screen shot image and the second screen shot image may include: removing a bottom region having a height that is a value obtained by subtracting the determined scroll height from the screen height and subtracting the top preset region height from the first screen shot image (i.e., removing the partial dynamic region and the bottom preset region from the first screen shot image), removing the top preset region from the second screen shot image, and stitching the removed first screen shot image and the removed second screen shot image to obtain a long screen shot image (as shown in (c) of fig. 10).

As shown in FIG. 11, the roll height G may be determined as H-H-hx-Hb-Ht. Similar to the steps described with reference to fig. 10, the step of obtaining a long screen shot image by stitching the first screen shot image and the second screen shot image may include: removing a bottom region having a height that is a value obtained by subtracting the determined scroll height from the screen height and subtracting the top preset region height from the first screen shot image (i.e., removing the partial dynamic region, the bottom preset region, and a region having a height hx immediately above the partial dynamic region from the first screen shot image), removing the top preset region from the second screen shot image, and stitching the removed first screen shot image and the removed second screen shot image to obtain a long screen shot image (as shown in (c) of fig. 11).

In addition, when the scrolling height is H-hx-Hb-Ht, the first screen capturing image and the second screen capturing image may be spliced to obtain a long screen capturing image by the method of searching the contrast area as described above, which will not be described herein.

Further, when the actual scroll height is smaller than the determined scroll height, the step of stitching the removed first screen shot image and the removed second screen shot image, described with reference to fig. 10 and 11, to obtain a long screen shot image may include: and removing the area with the height which is the difference between the determined rolling height and the actual rolling height from the removed second screen capturing image, and splicing the removed first screen capturing image and the removed second screen capturing image to obtain a long screen capturing image.

According to another example embodiment of the present disclosure, when the first and second screen shots include at least one preset area, a bottom area having a height that is a difference between the height of the first image and the determined scroll height may be removed from the first image by removing at least one preset area of the first and second screen shots to obtain corresponding first and second images, respectively, and the removed first and second images may be stitched.

In addition, when the actual scroll height is smaller than the determined scroll height, the step of stitching the removed first image and the removed second image may include: and removing a top area with the height being the difference between the determined rolling height and the actual rolling height from the second image, stitching the removed first image and the removed second image, and stitching at least one corresponding preset area at the corresponding position of the stitched image to obtain a long screen capturing image.

The method of obtaining a long screen shot image according to an example embodiment of the present disclosure may be applicable to both schemes of manually scrolling screen content (e.g., scrolling screen content up a distance by manually clicking a button) and automatically scrolling screen content (e.g., automatically scrolling a screen by a cell phone, scrolling screen content a specific distance at a time). The principle of the two schemes is the same, whether the scrolling is performed by clicking by a user or the mobile phone automatically scrolls, the screen capturing image of the screen is obtained, and then the screen capturing image is cut (or not cut) to obtain a long screenshot. The method for obtaining the long screen shot image can be applied to all schemes for combining the long screen shots through multiple screen shots. Regardless of the manner in which the individual screen shots are taken, there must be a cut line, and as long as there is a moving image, this moving image may appear on the cut line. To avoid the moving image being cut into two parts, the moving image must be identified and then properly scrolled to include the complete moving image in the screenshot image, so that the integrity of the moving image is maintained during stitching. Thus, the method of obtaining a long screen shot image according to an example embodiment of the present disclosure is applicable to both of the above-described schemes.

Fig. 12 is a flowchart illustrating an application scenario to which a method of obtaining a long screen shot image according to an example embodiment of the present disclosure is applied.

For example only, the current screen may include a top preset area and a bottom preset area, and the user may initiate a long screenshot function of automatically scrolling screen content at step S1210.

In step S1220, a screen shot image of the page (e.g., which may be referred to as a first screen shot image or an upper screen shot image) may be acquired.

In step S1230, the region information of the dynamic region and the bottom position information of the screen shot image may be obtained, and whether a part of the dynamic region exists at the bottom of the screen shot image and the height of the part of the dynamic region are determined based on the region information of the dynamic region and the bottom position information of the screen shot image.

In the case where a part of the dynamic region exists at the bottom of the screen shot image, in step S1240, it may be determined whether to end the screen shot. When the screen capturing is not ended (no at step S1240), at step S1250, the scroll height G may be determined as the upper screen capturing image height H-the height H of the partial dynamic region-the top preset region height Ht-the bottom preset region height Hb, and the page is scrolled according to the determined scroll height, and then another screen capturing image (for example, may be referred to as a second screen capturing image or a lower screen capturing image) of the page is acquired (return to step S1220). When the screen capturing is ended (yes at step S1240), since the user activates the long screen capturing function of automatically scrolling the screen content, it may occur that the actual scroll height is different from the determined scroll height when the last screen capturing image is acquired, and the actual scroll height of the last page may be compared with the determined scroll height at step S1260. In step S1270-1, when the actual scroll height is equal to the determined scroll height, the partial dynamic region and the bottom preset region may be removed from the upper screen shot image (i.e., the bottom region whose height is a value obtained by subtracting the determined scroll height from the screen height and then subtracting the top preset region height is removed from the upper screen shot image), the top preset region is removed from the lower screen shot image, the removed upper screen shot image and the removed lower screen shot image are stitched, and the stitched screen shot image may be used as the upper screen shot image to be stitched next time. In step S1280, it may be determined whether the splice is complete. When the stitching is not completed (no at step S1280), the procedure returns to step S1260, and the stitching is continued in the order in which the screen capture images are captured. Further, at step 1260, when the stitching of the last lower screen shot image is performed, it may be determined whether to further remove the lower screen shot image based on a comparison of the last actual scroll height of the page with the determined scroll height. In step S1270-2, when the actual scroll height of the last time of the page is smaller than the determined scroll height, a region whose height immediately below the top preset region is the difference between the determined scroll height and the actual scroll height is removed from the lower screen shot image from which the top preset region is removed, and the removed upper screen shot image and the removed lower screen shot image are stitched. When the stitching is completed (yes at step S1280), a long screen capturing image can be obtained.
