It is understood that the specific embodiments described herein are merely illustrative of the present disclosure and are not intended to limit the disclosure.

1 is a flowchart of a first embodiment of a screen capture method of a terminal device of the present disclosure, the screen capture method including:

Step S11: on the display interface of the terminal device when receiving the screenshot start instruction Shows the screen capture area.

The triggering manner of the start indication of the screenshot includes but is not limited to the following: triggering by a shortcut icon button; triggering by a button or a combination of keys; triggering by a display gesture; triggering by a voice instruction; shaking by picking up the terminal device, or A specified shape trigger is swiped in the air; triggered by an empty gesture.

The screen capture area on the display interface may be the entire display area or part of the display area. When the screen capture area is part of the display screen area, the screen capture area may be a rectangle, the default width of the rectangle screen capture area is the width of the display screen, and the height defaults to half of the height of the display screen, and the default coverage area of the display area, that is, the rectangular screen capture The center of the area coincides with the center of the display. Of course, the width of the rectangular screen capture area can also be half of the screen width. Embodiments of the present disclosure do not limit the length, width, and position of the rectangular screen capture area in the screen.

It is worth noting that the size, position and shape of the screen capture area may be preset or may be adjusted by the user. For example, if the user only wants to intercept the image information of half the width in the middle of the display screen, the width of the screen capture area can be adjusted to half of the width of the display screen, and then the screen capture area can be moved to the middle of the display screen. The user can also set the default position, size, transparency, color and other information of the screen capture area in the parameter setting function provided by the setting interface.

Step S12: Acquire an image corresponding to the screen capture area as an image to be stitched.

In this embodiment, when the screen capture area is initially determined, the terminal device acquires an image corresponding to the screen capture area. The initial determination of the screen capture area includes, but is not limited to, determining that when the screenshot start indication is received, the screen capture area is displayed on the display interface of the terminal device; after displaying the screen capture area, the user adjusts the shape, position, or The size is determined by triggering the confirmation operation.

In the embodiment of the present disclosure, the image corresponding to the screen capture area is an image displayed in the current screen capture area, thereby allowing the user to intercept the required image information more intuitively and conveniently. It should be understood that, in some other embodiments of the screen capture method of the present disclosure, acquiring the image corresponding to the screen capture area may further increase an image of a certain pixel width outside the boundary of the current screen capture area or exclude the boundary of the current screen capture area. An image with a certain pixel width.

Considering the arrangement rule of the image information of the terminal device, the rectangular screen capture area helps the user to intercept more complete image information, and avoids the user's inaccurate selection of the screen image. Redefining the screen capture area results in energy expenditure and saves operation time.

Before this step, when it is detected that the boundary of the screen capture area is dragged to the edge of the display screen interface, the display screen interface is controlled to scroll in the opposite direction of the drag direction. For example, when the lower boundary of the screen capture area is dragged to the lower edge of the display screen, the display interface scrolls upward; when the upper boundary of the screen capture area is dragged to the upper edge of the display screen, the display interface scrolls downward; When the left border of the screen capture area is dragged to the left edge of the display, the display interface scrolls to the right; when the right border of the screen capture area is dragged to the right edge of the display, the display interface scrolls to the left.

In an embodiment of the present disclosure, the user may change the image information in the screen capture area by dragging one or more boundaries of the screen capture area, or operate the mobile terminal to cause the content of the display screen to scroll, so that the mobile terminal automatically acquires The image corresponding to the screenshot of the next cycle is free of frequent manual operations by the user. At this time, if the user wants to pause scrolling, it is only necessary to drag the boundary of the screen capture area back by a certain distance so that the boundary leaves the edge of the display interface. By dragging the edge of the display interface to scroll the display interface, the user can control the screen capture content to facilitate the user to selectively intercept the content.

In some other embodiments of the present disclosure, if the display content has scrolled to the bottom, a prompt pops up to tell the user to scroll to the bottom, and the user can drag back to decide whether to remove the last portion of the display, or release the finger. Save screenshots directly.

Step S13: splicing the image to be spliced and the image corresponding to the screen capture area acquired in the next time period as the next image to be spliced; this step is repeatedly performed.

Repeating this step means that each time a screen corresponding to the screen capture area is obtained, the image corresponding to the screen capture area is spliced onto the image to be stitched to form a new image to be stitched, that is, the next image to be stitched.

In this embodiment, the image to be stitched and the image corresponding to the screen capture area acquired in the next time period have overlapping portions; this step is automatically executed in the background, and each acquired image to be stitched is saved in the terminal device. Memory or cache.

Step S14: Receive a screen capture end indication, and determine the current image to be stitched as a screen capture image.

The end of screen capture indication may include, but is not limited to, the following: triggering by a shortcut icon button; triggering by a button or a combination of keys; triggering by a display gesture; triggering by a voice command; shaking by picking up the terminal device, or waving in the air Specify shape triggering; trigger by gap gestures; Trigger by stopping scrolling the contents of the display and removing the finger; triggering by stopping the dragging of the border of the screen area and removing the finger.

In the latter two trigger modes, the user only needs to remove the finger, so that the finger leaves the display panel to save the screenshot image, and does not need to be triggered by other confirmation buttons or gestures, and the operation is simple and convenient to use.

The screen capture end instruction is received, and the splicing step of the repeated execution in step S13 is stopped. The last generated image to be stitched is taken as the current image to be stitched, that is, a screen shot image. After saving the screenshot image, a prompt will pop up to inform the user that the image has been saved and exit the program. The user can choose to view the generated screenshot image to confirm the screenshot.

The method of the embodiment of the present disclosure realizes continuous interception of multiple screens, and automatically synthesizes by algorithm to avoid the heavy workload of single interception and software synthesis, and the images are continuous, avoiding image distortion caused by misoperation or software defects. Or a synthetic error. It can capture multi-screen images of the display terminal efficiently, quickly and accurately.
