In order to further explain the technical solution provided by the embodiments of the present application, the following details are described with reference to the accompanying drawings and the detailed description. Although embodiments of the present application provide the method operational steps shown in the following embodiments or figures, more or fewer operational steps may be included in the method, either on a routine or non-inventive basis. In steps where there is logically no necessary causal relationship, the execution order of the steps is not limited to the execution order provided by the embodiments of the present application. The method may be performed sequentially or and in accordance with the method shown in the embodiments or drawings when the actual process or apparatus is performed.
Fig. 3 shows a flowchart of a long screen capturing method according to an embodiment of the present application. The method may be applied to the terminal device shown in fig. 1, which may include, but is not limited to, a mobile phone. As shown in fig. 3, the method may include the steps of:
Step S301, responding to the screen capturing operation input by the user, and detecting whether a rolling window is contained in the current display interface.
In an alternative implementation manner, the mobile phone can respond to the screen capturing operation input by the user to detect whether the current display interface contains a floating window or not; if the current display interface contains a floating window, determining whether the floating window is a rolling window; wherein, the floating window refers to a window covering part of the display screen of the terminal equipment;
Specifically, when detecting whether a floating window is included in the current display interface, the mobile phone can respond to screen capturing operation input by a user to acquire layer data of each layer included in the current display interface; determining the area of each layer based on the layer data of each layer; determining the area ratio of each layer to the display screen based on the areas of each layer respectively; and if at least one area ratio is within the preset area ratio range, determining that the current display interface comprises the floating window.
Illustratively, in one embodiment, as shown in fig. 4, it is assumed that fig. 4 is the current display interface of the mobile phone, and a widget 401 is included in fig. 4. Alternatively, the user may take a screen capture by: the user can execute a pull-down operation from the top of the mobile phone, open the pull-down menu bar of the mobile phone, as shown in fig. 5, and include a screen capturing button 501 in the pull-down menu bar of the mobile phone, and the user can click the screen capturing button 501 in the pull-down menu bar of the mobile phone to input the screen capturing operation. The mobile phone responds to the operation of clicking the screen capturing button 501 by the user, and can acquire the layer data of each layer contained in the current display interface of the mobile phone from the data Buffer (Buffer). For example, each layer included in the current display interface of the mobile phone may correspond to a set of Bitmap data, where each layer included in the current display interface of the mobile phone may include a status bar layer, a navigation bar layer, a background layer, and a widget layer, as shown in fig. 6, where 601 in (a) is a status bar layer; 602 in (b) is a navigation bar layer; (c) a background layer; 603 in (d) is a widget layer.
Because the portlet layer needs to be overlaid on top of the background layer, as shown in fig. 4, a layer of translucent area is typically carried on the bottom of the portlet layer, as shown in fig. 6 (d), with grey representing the translucent area. Therefore, after obtaining Bitmap data corresponding to each layer, the mobile phone needs to determine whether each layer contains a semitransparent region, if so, the semitransparent region is discarded, i.e. only an opaque region is reserved; specifically, after obtaining Bitmap data corresponding to each layer, the mobile phone may discard a semitransparent area included in one layer according to an Alpha value used for identifying transparency in the Bitmap data, for example, if the Alpha value is smaller than 255, which indicates that the area is a semitransparent area, the area may be discarded, as shown in fig. 7, and 701 is a widget layer after discarding the transparent area.
After the opaque areas in the layers are determined by the method, the mobile phone can determine the areas of the layers according to Bitmap data corresponding to the opaque areas of the layers; determining the area ratio of each layer to the mobile phone display screen based on the determined areas of each layer and the area of the mobile phone display screen; if the area ratio is within the preset area ratio range, determining that the current display interface comprises a suspension window; if the area ratio is not within the preset area ratio range (thred ), determining that the current display interface does not contain a floating window, wherein thred and thred are greater than zero.
For example, it is assumed that the preset area ratio range is (20:100, 90:100), where the minimum value of the area ratio range may be set according to the area ratio of the common layer such as the status bar layer or the navigation bar layer, which is generally included in the mobile phone display interface, to the mobile phone display screen, so that the area ratio is greater than the area ratio of the common layer to the mobile phone display screen; the maximum value of the area ratio range can be set according to the area ratio of the suspension window area which is usually the maximum to the display screen of the mobile phone.
Assuming that the area ratio of the determined status bar layer to the mobile phone display screen is 5:100, the area ratio of the navigation bar layer to the mobile phone display screen is 10:100, the area ratio of the background layer to the mobile phone display screen is 100:100, the area ratio of the small window layer to the mobile phone display screen is 50:100. therefore, the area ratio of the status bar layer, the navigation bar layer, the background layer and the mobile phone display screen is not within the preset area ratio range, and the area ratio of the widget layer to the mobile phone display screen is within the preset area ratio range, so that the mobile phone can determine that the current display interface contains a floating window, i.e. the widget 401 is a floating window.
In an alternative embodiment, after the floating window is detected in the above manner, a screen capturing control for the floating window may be displayed, for example, as shown in fig. 8, a small window screen capturing button 801 may be displayed on the lower right side of the display screen of the mobile phone, where the small window screen capturing button 801 is an optional screen capturing control for the floating window, a user may click on the small window screen capturing button 801, and the mobile phone may perform a screen capturing operation on the interface currently displayed by the floating window 401 in response to the user clicking on the small window screen capturing button 801.
In an optional implementation manner, after detecting the floating window in the above manner, the mobile phone may obtain a first interface currently displayed by the floating window; and performing rolling operation on the floating window; acquiring a second interface displayed by the scrolled floating window, and comparing the first interface with the second interface; and if the first interface and the second interface are different, determining that the floating window is a rolling window.
For example, in one embodiment, after detecting that the widget 401 is a floating window, the mobile phone may first acquire an image of a current display interface of the floating window, that is, a first interface, and establish a coordinate system based on a position of the floating window, as shown in fig. 9, may use a vertex of an upper left corner of the floating window as an origin O of coordinates, establish an X-axis along a width of the floating window, establish a Y-axis along a height of the floating window, and determine a coordinate center point P, where X max may represent a wide value of the floating window, and Y max represents a high value of the floating window. After the establishment is completed, the mobile phone may simulate a touch screen sliding operation, that is, a scrolling operation, by using the coordinate center point P as a starting point, and move upwards by a distance Y max/thred 3, where thred3 is any value greater than or equal to 2, for example, thred3 may be 3. After the scrolling operation is completed, the mobile phone may acquire an image of the interface currently displayed by the scrolled floating window, that is, the second interface, as shown in fig. 10.
After the images shown in fig. 9 and 10 are obtained, the mobile phone can compare the images shown in fig. 9 and 10, for example, the mobile phone can calculate the difference value of pixels between corresponding pixels in the images shown in fig. 9 and 10 by adopting an SAD algorithm, and calculate the sum of absolute values of the difference values, and judge whether the images shown in fig. 9 and 10 have the difference by comparing the sum of absolute values with a preset threshold value, wherein the preset threshold value can be a value close to 0 or can be set according to the size of the images, and for example, when the number of pixels contained in the images is more, the threshold value can be set to 100; when the image contains fewer pixels, the threshold may be set to 20. If the sum of the absolute values is less than the preset threshold value, indicating that no difference exists between the images shown in fig. 9 and 10, indicating that the floating window cannot roll; if the sum of the absolute values is greater than the preset threshold, indicating that there is a difference between the images shown in fig. 9 and 10, it is indicated that the floating window is scrollable, i.e., the floating window is a scrolling window.
In another optional embodiment, the current display interface of the mobile phone may include a plurality of floating windows, where the user may select one floating window from the plurality of floating windows detected by the mobile phone as a target floating window, and the mobile phone responds to the operation of selecting the target floating window by the user to detect whether the target floating window is a rolling window, and in a specific embodiment, similar to the above steps, details are not repeated herein.
Step S302, if the current display interface contains a rolling window, displaying a long screen capturing control for the rolling window.
Step S303, in response to a trigger operation for the long screen capturing control, a long screen capturing picture is generated based on the scroll window.
In an alternative embodiment, if it is determined in step S301 that the current display interface of the mobile phone includes a scrolling window, the mobile phone may display a long screen capturing control for the scrolling window, for example, as shown in fig. 11, a small window long screen capturing button 1101 is an optional long screen capturing control for the scrolling window, the user may click the small window long screen capturing button 1101, and in response to an operation of clicking the small window long screen capturing button 1101 by the user, the mobile phone may generate a long screen capturing picture based on the scrolling window.
In an alternative embodiment, after the scroll window is detected in step S301, when a long screen capture is generated based on the scroll window, since not all the areas within the scroll window may be scrolled, it is necessary to detect a scrollable area included in the scroll window. Specifically, the mobile phone may compare the differences between the images shown in fig. 9 and fig. 10 to obtain a corresponding difference map, as shown in fig. 12, gray represents a non-difference region, and black represents a difference region, and since the scrolling mode of the scrolling window is scrolling up and down, the scrollable region and the height H of the scrollable region contained in the scrolling window may be initially determined according to the difference map shown in fig. 12.
Specifically, fig. 12 is a difference chart corresponding to the images shown in fig. 9 and fig. 10, where the mobile phone may determine the vertex coordinates of the difference area included in the difference chart, where the vertex coordinates of the difference area are the vertex coordinates of the scrollable area, and a coordinate system where the vertex coordinates of the scrollable area are located is consistent with a coordinate system where the vertex coordinates of the difference area are located.
In an optional implementation manner, after the position and the height of the scrollable area are preliminarily determined in the above manner, the mobile phone can execute at least one scrolling operation for the scrolling window, and a first image and a second image corresponding to each scrolling operation are respectively obtained; and splicing the first image and the second image corresponding to each scrolling operation in sequence to generate a long screen capturing picture. The first image is an interface image of a scrolling window before scrolling operation; the second image is an interface image of the scroll window after the scroll operation is performed.
Illustratively, in one embodiment, the user may click the widget long screen capturing button 1001 in fig. 11, and the mobile phone obtains an image Pic0 of the scrolling window in response to the user clicking the widget long screen capturing button 1101, and simulates a touch screen sliding operation, i.e., a scrolling operation, by a distance H/thred4 upwards with a center point of the determined scrollable area as a starting point, and obtains an image Pic1 of the scrolling window, wherein thred may be any integer greater than 0; for example, as shown in fig. 13, H is the height of the scrollable area, Q is the center point determined according to the vertex coordinates of the scrollable area, after the image Pic0 is obtained, the mobile phone may simulate a touch screen sliding operation with the Q point as the starting point, move up by H/thred4 distance, and obtain the image Pic1 of the scrolling window, repeat the above steps, obtain the image Pic2 of the scrolling window, and compare Pic1 and Pic2, if Pic1 and Pic2 have no difference, it indicates that scrolling has reached the bottommost end, and stop scrolling; if Pic1 and Pic2 are different, scrolling is continued until scrolling to the bottommost end or feedback operation of the user is received, etc.
In one embodiment, assuming that Pic1 and Pic2 are not different, the finally obtained image of the scrolling window contains Pic0 and Pic1, where Pic0 is the first image and Pic1 is the second image. The first image and the second image may be stitched together to generate a long screenshot: as shown in fig. 14, (a) is Pic0, and (b) is Pic1, after images Pic0 and Pic1 of the rolling window are obtained, the mobile phone may perform difference on the images Pic0 and Pic1 to obtain a corresponding difference map Diff01, as shown in fig. 15, where gray represents the non-difference region and black represents the difference region. After the difference map is obtained, diff01, the mobile phone can determine the coordinate position of the difference region contained in the difference map Diff01, and the coordinate position of the difference region can be represented by the vertex coordinates of each vertex. The mobile phone can determine the vertex coordinates of the splicing area according to the vertex coordinates of the difference area, extract corresponding splicing areas Roi0 and Roi1 from the images Pic0 and Pic1 according to the vertex coordinates of the splicing area, and splice the Roi0 and the Roi1 to obtain a long screenshot spliced picture.
For example, assuming that the vertex coordinates of four vertices of the difference region included in the difference map Diff01 are A1 (1, 1), B1 (5, 1), C1 (1, 7), D1 (5, 7), respectively, the vertex coordinates of the stitching region are a (1, 1), B (5, 1), C (1, 7), D (5, 7). After the vertex coordinates of the splicing area are determined, the splicing area Roi contained in each image can be extracted from the acquired images Pic0 and Pic1 of the rolling window according to the vertex coordinates of the splicing area, as shown in fig. 16, (a) is the splicing area Roi0 in Pic0, and (b) is the splicing area Roi1 in Pic1, after the splicing areas Roi0 and Roi1 are determined, the Roi0 and Roi1 can be spliced, and a long screenshot spliced picture is obtained. The specific steps for splicing the Roi0 and the Roi1 will be described in detail below, and will not be repeated here. After the long screen shot spliced picture is obtained, the long screen shot spliced picture and a non-spliced area of any image can be fused to generate the long screen shot picture.
In one embodiment, the acquired first image and second image of the rolling window may be divided into two parts of a stitched area and a non-stitched area, where the vertex coordinates of the stitched area are consistent with those of the scrollable area included in the rolling window, and the non-stitched area is the rest of the first image and the second image except the stitched area.
In another embodiment, it is assumed that the finally obtained image of the scrolling window includes Pic0, pic1 and Pic2, as shown in fig. 17, (a) is Pic0, (b) is Pic1, (c) is Pic2, after the obtaining is completed, the mobile phone may perform a difference on the images obtained in two adjacent times to obtain a corresponding difference map, as shown in fig. 18, (a) is a difference map Diff01 corresponding to Pic0 and Pic1, and (b) is a difference map Diff12 corresponding to Pic1 and Pic 2; wherein gray 1201 represents a non-differential area, black 1202 represents a differential area, after obtaining differential graphs Diff01 and Diff12, the mobile phone can determine the vertex coordinates, namely the coordinate positions, of the differential areas contained in the differential graphs Diff01 and Diff12, and determine the vertex coordinates of the splicing area according to the vertex coordinates of the differential areas.
Illustratively, it is assumed that the vertex coordinates of the four vertices of the difference region included in the difference map Diff01 are A1 (1, 1), B1 (5, 1), C1 (1, 7), D1 (5, 7), respectively; the vertex coordinates of the four vertices of the difference region included in the difference map Diff12 are A2 (1, 1), B2 (6, 1), C2 (1, 7), D2 (6, 7), respectively, and therefore, the vertex coordinates of the stitching region are a (1, 1), B (6, 1), C (1, 7), D (6, 7); wherein A is the maximum value of each coordinate point in A1 and A2; b is the maximum value of each coordinate point in B1 and B2; c is the maximum value of each coordinate point in C1 and C2; d is the maximum value of each coordinate point in D1 and D2. After the vertex coordinates of the splicing area are determined, the splicing area Roi contained in each image may be extracted from the acquired images Pic0, pic1 and Pic2 of the rolling window according to the vertex coordinates of the splicing area, as shown in fig. 19, (a) is the splicing area Roi0 in Pic0, (b) is the splicing area Roi1 in Pic1, and (c) is the splicing area Roi2 in Pic2, and after the splicing areas Roi0, roi1 and Roi2 are extracted, the Roi0, roi1 and Roi2 may be spliced.
In one embodiment, the example of splicing the Roi0 and the Roi1 is taken as an example, since only the change in the Y direction needs to be considered, the offset can be calculated by using a template matching method, specifically, an area with the height of H/thred4 can be taken as a template from the top of the Roi1, where H is the height of the spliced area, and can be determined according to the vertex coordinates of the spliced area. thred4 is any value greater than 0; the search is performed in the Y-axis direction in the Roi0, i.e., the search is performed from top to bottom in the Roi0 until the region that best matches the template in the Roi1 is found in the Roi0, and the displacement amount in the Y-axis direction when the best matching region is found is defined as the offset mvY.
For example, assuming thred is 4, i.e., starting from the top of Roi1, taking the H/4-high region as a template, as shown in fig. 20, searching from top to bottom in Roi0 for the H/4-high region, assuming that when the best matching region is found, the displacement in the Y-axis direction is 5, i.e., the offset mvY between the top of Roi0 and the top of the best matching region is 5, after determining the offset mvY, the Roi0 may be divided into two parts according to the offset in the Y-axis direction, and the upper half of Roi1 and Roi0 may be spliced to obtain a spliced picture, and referring to the above steps, the obtained spliced picture and Roi2 may be spliced again to obtain a long-screen spliced picture.
