detailed description

The technical problems, the technical solutions, and the advantages of the present invention will be more clearly described in the following description.

As shown in FIG. 1 , a method for screen capture of a terminal according to an embodiment of the present invention includes:

Step 101: After detecting that the terminal enters the screen capture mode, determine an area as a screen cut reference area on the display interface of the terminal screen, and acquire an image in the screen cut reference area as an initial screen capture image.

Here, the screen reference area may be a full screen area or a part of the area on the screen display interface. The shape of the screen reference area may be a rectangular frame.

The terminal may enter the screen capture mode after receiving an instruction to enter the screen capture mode input by the user through a certain combination button or an icon on the screen. The combination button can be a combination of a power button and a volume button.

Step 102, when the screen scrolling is detected, each time the screen is scrolled by a preset distance, according to Performing a screen shot for the image change of the screen reference area, and acquiring the final screen image according to the image obtained by the multiple screen shots and the initial screen shot image.

Here, each time the screen is scrolled by a preset distance, a screen capture is performed according to the image change of the screen reference area, and the final screen capture image is obtained according to the image obtained by the multiple screen captures and the initial screen capture image.

Step 103: Output the final screenshot image.

The method for intercepting the screen of the terminal in the embodiment of the invention enables the user to realize continuous screen capture and automatically stitching and generate long pictures only by sliding the screen, which is easy to operate and can intercept non-full-screen content, thereby providing users with more convenient and quick storage and sharing. The means of data enhances the user experience. The method for generating a long picture by the existing screen capture has the problem that the third-party application needs to be used, the operation steps are cumbersome, and the non-full-screen content cannot be processed.

In other embodiments of the present invention, in the step 101, the step of determining an area as a screen reference area on the display interface of the terminal screen includes:

Step 1011: Detect a touch operation of the user on the screen, and determine the screen reference area on the display interface of the screen according to the start position and the end position of the touch operation.

At this time, according to the starting position and the terminal position of the user's touch operation on the screen, the screen reference area is determined, so that the user can select the image content to be saved on the screen.

In other embodiments of the present invention, it is assumed that the screen reference area is a rectangular frame, as shown in FIG. 2, according to the coordinate point A of the starting position of the user's touch operation on the screen (ie, the finger first touches the coordinate point of the screen) Corresponding transverse line segment L1 (line segment along the screen transverse direction) and longitudinal line segment L2 (line segment along the longitudinal direction of the screen), coordinate point B of the end position position (ie, the coordinate point of the finger leaving the screen) corresponding to the transverse line segment L3 and the longitudinal line segment L4, Determine the rectangle, which is the size and position of the screen reference area.

In other embodiments of the present invention, the steps of step 102 above include:

Step 1021: when the screen scrolls a preset distance each time; according to the screen scrolling direction, the spliced image scrolled from outside the screen reference area to the screen reference area is intercepted, and according to The obtained stitched image is stitched with the previously saved screen capture image, or the previously saved screen capture image is cropped, and the image of the preset distance is cut out from the previously saved screen capture image.

The image after each stitching or clipping is saved as a new screen capture image, and when the screen scrolls the preset distance for the first time, the initial screen capture image is used as the screenshot image saved last time.

Here, each time the screen scrolls by a preset distance, according to the screen scrolling method, the stitched image is clipped for splicing or the screen cut image is cropped. For example, a screen may be set in the positive direction. If the screen scrolling direction is the positive direction of the screen, the stitched image is intercepted for splicing. If the screen scrolling direction is the direction in which the screen is in the opposite direction, the screen image is cropped.

For example, if the spliced image F2 is obtained when the screen scrolls the preset distance for the first time, F2 is spliced with the previously saved screen image, that is, the initial screen image F1, and a new screen image F=F1+F2 is obtained for saving; Assuming that the screen scrolls the preset distance for the second time, the previously saved screen capture image is cropped, the image F3 whose length is the preset distance is cropped, and a new screen capture image F=F1+F2-F3 is saved.

Among them, when splicing or cropping the previously saved screenshot image, the splicing or cropping is started from the tail of the image.

Step 1023: When the screen stops scrolling, the currently saved screen capture image is used as the final screen capture image.

Here, when the screen stops scrolling, the currently saved screen capture image is taken as the final screen capture image.

At this time, the user can continuously splicing the screen image by sliding the screen to obtain a long picture. When the screen image exceeds the expected range, the screen image can be cropped by sliding the screen to remove the redundant image, thereby providing users with more convenient and quicker. The means of saving and sharing data enhances the user experience.

Since the user intercepts the image on the sliding screen, the height of the last frame of the image is often not In the other embodiments of the present invention, before the step 1023, the method may further include:

Step 10231, if the screen is scrolled by a preset distance, and then continues to scroll by a distance and stops, and the distance of continuing scrolling is less than the preset distance, when the screen continues to scroll; according to the screen scrolling direction, the interception is performed. Scrolling to the spliced image in the screen reference area outside the screen reference area, and splicing according to the obtained spliced image and the previously saved screen image, or cropping the previously saved screen image, from the previous saved screen capture An image whose length is the distance to continue scrolling is cropped in the image.

Here, each time the screen is scrolled by the preset distance, the image scrolled from the outside of the screen reference area to the screen image of the previous save is spliced into the previously saved screen image, or the previously saved crop image is cropped. If the screen continues to scroll for a distance after scrolling the preset distance, and the distance is less than the preset distance, the image is stitched again or the image is cropped when the screen continues to scroll.

At this time, before the screen stops scrolling, if the actual distance of the last scroll is less than the preset distance, the stitched image of the distance is intercepted to splicing or cropping the image of the distance to ensure a complete image of the expected range.

In another embodiment of the present invention, in the above step 1021 or the above step 10231, the capturing a stitched image from outside the screen reference area to the screen reference area according to the screen scrolling direction, and according to the obtained stitching The steps of splicing an image with a previously saved screenshot image, or cropping the previously saved screen capture image include:

Step 1024: If the screen scrolling direction is the preset screen cutting direction, the spliced image that is scrolled from outside the screen reference area to the screen reference area is intercepted, and the spliced image is spliced according to the previously saved screen image. .

Here, if the screen scroll direction is the positive direction of the screen, the image is stitched.

Step 1025, if the screen scrolling direction is the opposite direction of the positive direction of the screen capture, the previous time The saved screenshot image is cropped.

Here, if the screen scroll direction is the opposite direction of the positive direction of the screen, the image is cropped.

At this time, the user can select the image to be spliced or cropped according to the needs, which is convenient for the user's operation and use, and improves convenience and intelligence.

Further, after the foregoing step 1011, the method may further include:

Step 1012: Determine a positive direction of the screen according to the starting position and the ending position of the touch operation.

At this time, the positive direction of the screen can be determined according to the user's touch operation. For example, the horizontal line segment corresponding to the coordinate point of the start position of the touch operation may be used as the starting line, and the horizontal line segment corresponding to the coordinate point of the end position of the touch operation may be used as the ending line, and the direction from the ending line to the starting line is determined to be the positive direction of the screen. As shown in FIG. 2, L3 can be pointed in the direction of L1, that is, the screen is scrolled up as the positive direction of the screen, and L1 is directed to the direction of L3, that is, the screen is scrolled downward as the opposite direction of the positive direction of the screen. Of course, according to the demand, the direction of L1 pointing to L3 is taken as the positive direction of the screen, or L4 is pointed to the direction of L2, that is, the screen is scrolled to the left as the positive direction of the screen, or L2 is pointed to the direction of L4, that is, the screen is scrolled to the right. The screen is in the right direction.

Further, for accurate sampling, the preset distance is less than or equal to half of the length of the rectangular frame (the length along the lateral direction of the screen) or the height (the height along the longitudinal direction of the screen). Wherein, when the screen is scrolled downward or upward to the positive direction of the screen, the preset distance is less than or equal to half of the height of the rectangular frame. When the screen is scrolled left or right to the positive direction of the screen, the preset distance is less than or equal to the length of the rectangular frame. Half of it.

An application flow of the method for splicing the terminal screen capture of the embodiment of the present invention is exemplified as follows.

As shown in FIG. 3, a method for screen capture of a terminal according to an embodiment of the present invention includes:

Step 301, the terminal receives the instruction that the user enters the screen capture mode by pressing the input of the power button and the volume key, and then enters the screen capture mode.

Step 302: Detect a touch operation on the screen by the user, and determine a rectangular frame according to a horizontal line segment and a vertical line segment corresponding to the coordinate point of the start position of the touch operation on the screen, and the horizontal line segment and the vertical line segment corresponding to the coordinate point of the end position position. , that is, the size and position of the screen reference area. And the image in the rectangular frame is acquired as the initial screen shot image F1.

Step 303, the horizontal line segment corresponding to the coordinate point of the starting position of the touch operation is used as the starting line, and the horizontal line segment corresponding to the coordinate point of the end position of the touch operation is used as the ending line, and the direction from the ending line to the starting line is determined as the positive direction of the screen. .

Here, according to the user's operating habits, the general screen orientation is the direction in which the screen scrolls upward. Of course, the positive direction of the screen can also be the direction in which the screen scrolls down, scrolls left or scrolls to the right.

Step 304: When the screen scrolling is detected, and the screen scrolling direction is the positive direction of the screen, the screen scrolls the preset distance H, and the stitched image is scrolled from the outside of the rectangular frame to the rectangular frame, and is spliced with the previously saved screen image. The stitched image is saved as a new screenshot.

If the screen is scrolled by the preset distance H for the ith time, the spliced image Fi that is scrolled from outside the rectangular frame to the rectangular frame is intercepted, and spliced with the previously saved screenshot image to obtain a new screenshot image F=F1+F2+...+F(i -1) +Fi. Where i is an integer greater than or equal to 1.

Step 305: If the screen continues to scroll by a distance H0 (H0<H) after stopping the preset distance H, the screen is scrolled H0, and the spliced image is scrolled from the outside of the rectangular frame to the rectangular frame. A saved screenshot of the screen is stitched together.

Step 306, when the screen stops scrolling, the currently saved screen capture image is output as the final screen capture image.

At this point, a long picture with multiple screen stitchings is obtained.

If the image stitched by multiple screens is out of the expected range, you can slide the screen in the opposite direction to crop the excess area. An application flow of the method for cropping the terminal screen capture according to the embodiment of the present invention is as follows.

As shown in FIG. 4, a method for screen capture of a terminal according to an embodiment of the present invention includes:

Step 307, after performing the above step 305, when the screen scrolling is detected, and the screen scrolling direction is the opposite direction of the screen cutting direction, the screen is cut by the preset preset distance H, and the previously saved screen image is cropped, and saved from the previous time. The end of the screen capture begins cropping the image of length H, and each cropped image is saved as a new screenshot.

If the preset scroll distance H is scrolled for the rth time, the image Fr' of length H is cropped from the end of the previously saved screen capture image to obtain a new screen capture image:

F=F1+F2+...-F(i-1)+Fi-F1'-F2'-...-F(r-1)'-Fr'.

Where r is an integer greater than or equal to one.

Step 308, if the screen continues to scroll a distance h0 (h0 < H) after a preset scroll distance H, and then stops, when the screen scrolls h0, the image of length h0 is trimmed from the tail of the previously saved screen capture image. The cropped image is saved as a new screenshot.

Step 309, when the screen stops scrolling, the currently saved screen capture image is output as the final screen capture image.

At this point, a long picture that fits the expected range after cropping is obtained.

In summary, the method for intercepting a screen of a terminal in the embodiment of the present invention enables a user to continuously cut a screen and automatically stitch and generate a long picture by simply sliding the screen, which is easy to operate and can intercept non-full-screen content, thereby providing users with more convenient and quicker.
