Detailed Description
The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are some, not all, embodiments of the present invention. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
As in the background section, people often need to cut the size of an image, for example, when a photo is sent to a friend for sharing, or when a certain certificate and a file photo are uploaded. At present, the image is cut by opening a picture, then clicking to edit, at this time, entering an image editing interface, and then the user selects to cut the image. In the clipping process, when the clipping boundary is controlled by fingers, the clipping boundary cannot be precisely controlled due to the shielding of the fingers, so that the user is often dissatisfied with the clipping result and repeatedly clips, and the image clipping operation is complex. Moreover, the image content can be shielded when fingers are placed on the cutting boundary, so that a user cannot see the cutting condition of the boundary part, accurate adjustment cannot be realized, and the cutting effect is poor.
In order to solve the above problem, an embodiment of the present invention provides an image processing method, and referring to fig. 1, fig. 1 shows a schematic flow chart of an image processing method provided by an embodiment of the present invention; the method is applied to the electronic equipment with the flexible screen, and comprises the following steps:
s101, receiving a first bending operation of a user on the flexible screen under the condition that a first image is displayed on a display interface of the flexible screen;
the user can bend the flexible screen by one hand or both hands.
S102, determining a target cutting boundary line of the first image according to the curvature of the flexible screen corresponding to the first bending operation;
different bending forces can cause the flexible screen to have different curvatures, and the curvatures reflect the bending degrees of the flexible screen. In this embodiment, the cutting boundary line of the first image changes with the bending degree. For example, as shown in fig. 2, fig. 2 is a schematic diagram illustrating bending of a flexible screen according to an embodiment of the present invention, where when a curvature of the flexible screen increases, the first trimming boundary line may be close to a middle of the first image, and when the curvature of the flexible screen decreases, the first trimming boundary line may be close to two sides of the first image.
S103, receiving a first input of a user to the flexible screen;
the first input here refers to an input for determining clipping input by the user after the target clipping boundary line is moved to a position desired by the user. The first input may be an input operation of clicking a confirmation button on the display interface or on the side of the electronic device, or may be a slide input or the like input on the display interface, and the specific content of the first input is not limited in the present invention.
And S104, responding to the first input, removing the part, which is positioned outside the target cutting boundary line, in the first image according to the target cutting boundary line to obtain a target image.
And after the user inputs the first input for determining the cutting, cutting the first image according to the target cutting boundary line, and reserving partial images inside the target cutting boundary line to finish the image cutting operation.
In the embodiment of the invention, the position of the target cutting boundary line in the first image is controlled by the curvature of the flexible screen after the user bends the flexible screen, and because the finger of the user does not need to move in the image display interface in the process, the shielding of the finger on the cutting boundary line can be reduced, so that the cutting boundary line can be quickly and accurately adjusted to the required position under the condition of accurate cutting, the image cutting operation is simplified, and the cutting effect is better
In some embodiments of the invention, referring to fig. 3, the method may comprise:
s201, receiving a first bending operation of a user on a flexible screen under the condition that the user touches a display interface on which a first image is displayed;
in this embodiment, when the user performs the first bending operation on the flexible screen, the user needs to touch the screen portion of the electronic device, but cannot touch only other portions of the electronic device, such as the back panel. Only when the user touches the screen, the electronic device considers that the image cutting operation is currently performed, and then the position of the first cutting boundary line in the first image is adjusted.
The part of the user touching the display interface may be a finger or other parts, such as a palm. In addition, the number of the parts of the user touching the display interface may be one or more, for example, one finger or two fingers.
S202, adjusting the position of a first cutting boundary line of the first image in the first image according to the curvature of the flexible screen corresponding to the first bending operation;
the first bending operation causes the flexible screen to bend, the curvature of the bending corresponding to the positions of the first cut boundary lines. The first trimming boundary line here refers to a trimming boundary line adjustable within the first image.
S203, under the condition that a user does not touch the flexible screen, taking the current position of the first cutting boundary line as a target cutting boundary line, and locking the position of the target cutting boundary line in the first image;
after the user bends the flexible screen under the condition of touching the flexible screen, if the subsequent user does not touch the flexible screen any more, the adjustment of the first cutting boundary line is indicated to be completed by the user, and the current position of the first cutting boundary line is the position desired by the user, so that the image cutting can be performed. However, since the flexible screen is currently in a bent state, if the user clicks the trimming button, the position of the target trimming boundary line may be moved, so that in order to avoid the deviation of the target trimming boundary line, the embodiment locks the position of the target trimming boundary line after the user does not touch the flexible screen, thereby ensuring the accuracy of the trimming boundary line. For example, two thumbs of the user touch the flexible screen and perform a bending operation, and then the user releases the two thumbs, the position of the target trimming boundary line is locked, and the subsequent user can release the flexible screen to restore the flat state.
S204, receiving a first input of a user to the flexible screen;
and S205, in response to the first input, removing the part, which is positioned outside the target cutting boundary line, in the first image according to the target cutting boundary line to obtain a target image. S204-S205 are similar to S103-S104 in FIG. 1 and are not described herein again.
In this embodiment, whether the image cutting process is performed currently is judged by whether the user touches the flexible screen in the bending process, so that the image cutting and other operations are distinguished, and the occurrence of mistaken cutting is reduced. In addition, in the embodiment, after the flexible screen is bent, the contact part between the user and the flexible screen is lifted, so that the target cutting boundary line is locked, the situations that the target cutting boundary line is deviated when the cutting is determined, or the target cutting boundary line needs to be adjusted repeatedly due to the fact that the user slides, and the like are avoided, and the efficiency and the accuracy of image cutting are improved.
In addition, the above embodiment only defines that the first bending operation needs to be performed when the user touches the flexible screen, but the present invention does not limit the position of the touch point between the user and the flexible screen, and the position of the touch point between the user and the flexible screen may move during the first bending operation performed by the user. This way, the blocking of the cutting boundary line by the user's finger during the first bending operation can be avoided.
In some embodiments, optionally, before S101 or S201, the method further includes:
determining a touch point of a user on the flexible screen;
and determining the initial position of the first cutting boundary line according to the position of the touch point. As shown in fig. 4, fig. 4 is a schematic diagram illustrating a touch point according to an embodiment of the present invention.
Before moving the first trimming boundary line, the initial position of the first trimming boundary line needs to be determined, in this embodiment, the initial position of the first trimming boundary line is determined according to the touch point of the user initially falling on the flexible screen, and the trimming range of the first image can be preliminarily determined, so that the trimming position can be conveniently adjusted subsequently, and the adjustment times of the user on the first trimming boundary line is reduced.
In addition, in some other embodiments, the determining the initial position of the first trimming boundary line according to the position of the touch point may include: and taking the innermost tangent line of the touch points as the initial position of a first cutting boundary line, wherein the included angle between the first cutting boundary line and the connecting line of the two touch points is larger than a preset angle. For example, when two thumbs of the user touch the left side and the right side of the flexible screen, the first trimming boundary line is parallel to the left side and the right side of the flexible screen and is basically vertical to a connecting line of the two thumbs. The innermost side of the touch point refers to the side, closest to the center of the flexible screen, of the touch point, and the mode can reduce the shielding of the fingers of the user on the first cutting boundary line, so that the user can conveniently and accurately determine the position of the first cutting boundary line.
In other embodiments, the initial position of the first trimming boundary line may also be directly set as the boundary position of the first image, which is not limited in the present invention.
In some embodiments of the invention, the first bending operation comprises: bending any two opposite edges of the flexible screen; the first trimming boundary line includes: two straight lines parallel to the opposite sides.
In this embodiment, the first bending operation is a bending operation on two opposite sides of the flexible screen, for example, a bending operation on two left and right sides of the flexible screen, or a bending operation on two upper and lower sides. That is, in the present embodiment, the trimming boundary line of two opposite sides in the first image can be controlled, and this manner of determining the double-sided trimming boundary line has higher efficiency of image trimming and simpler user operation than the manner of determining the single-sided trimming boundary line each time.
Optionally, the above is only one specific embodiment, the first bending operation may also be a bending operation on any one edge of the flexible screen, and the first trimming boundary line includes: a straight line parallel to the side on which the first bending operation is performed. The invention is not limited in this regard.
In other embodiments, optionally, after the target trimming boundary line of two or one side of the first image is determined through the first bending operation, the currently determined target trimming boundary line may be locked by canceling the touch on the flexible screen, and then, the target trimming boundary line of the remaining side of the first image is further confirmed by continuing to the foregoing embodiments. For example, the first bending operation is a bending operation on the left side and the right side of the flexible screen for the first time, then target cutting boundary lines of the left side and the right side of the first image are determined, the user finger leaves the flexible screen, the currently determined target cutting boundary lines of the left side and the right side are locked, then the upper side and the lower side of the flexible screen are subjected to bending operation, the target cutting boundary lines of the upper side and the lower side of the first image are determined, the user finger leaves the flexible screen, the currently determined target cutting boundary lines of the upper side and the lower side are locked, and finally cutting is performed according to the first input.
In other embodiments of the present invention, as shown in FIG. 5, the method may comprise:
s301, determining a touch point of a user on the flexible screen;
s302, determining an initial position of the first cutting boundary line according to the position of the touch point. As shown in fig. 6, fig. 6 is a schematic diagram illustrating an initial position of a first trimming boundary line according to an embodiment of the present invention. S301-S302 are similar to the above embodiments and will not be described herein.
S303, receiving a second input of the user;
the second input here refers to an input operation for informing the electronic device to start fine adjustment, for example, the second input here may be a continuous touch input to the flexible screen, that is, the position where the user touches the flexible screen remains unchanged and the touch time reaches a preset time period, for example, 3S, in which case S303 to S304 need to be executed first, and then S305 needs to be executed.
Or, in other embodiments, S305 and S303 to S304 may be executed simultaneously, where the second input is a bending input of the user, that is, the electronic device may execute the operation of S304 once detecting that the first bending operation is started, and since the first bending operation may last for a long time, the second input in this embodiment only refers to the initially received bending input, that is, the tiling operation of S304 may be executed when the user just starts to bend.
S304, responding to a second input, and performing tiled display on partial images in the first cutting boundary line along a direction perpendicular to the first cutting boundary line to obtain a second image and a second cutting boundary line; as shown in fig. 7, fig. 7 is a schematic view illustrating a tiling scheme provided by an embodiment of the present invention.
Since the partial image inside the first trimming boundary line in the first image may be small, the partial image inside the first trimming boundary line is tiled in the present embodiment in order to facilitate the user to perform a subsequent fine operation. In this embodiment, when the first clipping boundary line is parallel to the left and right boundaries of the electronic device, the partial image within the first clipping boundary line may be tiled to the left and right boundaries of the electronic device.
Of course, the above is only a partial embodiment, and in other embodiments, the partial image within the first clipping boundary line may be fixed and tiled to the left and right boundaries of the electronic device, which is not limited by the present invention.
S305, receiving a first bending operation of a user on the flexible screen under the condition that the user touches an image display interface on which a second image is displayed; s305 is similar to S201 in fig. 2, and is not described again here.
S306, adjusting the position of the second cutting boundary line in the second image according to the curvature of the flexible screen corresponding to the first bending operation;
since the second trimming boundary line is within the tiled second image, which is equivalent to enlarging a partial image of the first image within the first trimming boundary line, a more accurate trimming position can be obtained by adjusting the position of the second trimming boundary line.
S307, under the condition that the user does not touch the flexible screen, taking the current position of the second cutting boundary line as a target cutting boundary line, and locking the position of the target cutting boundary line in the first image;
s308, receiving a first input of a user to the flexible screen;
s309, responding to the first input, and removing the part, which is positioned outside the target cutting boundary line, in the first image according to the target cutting boundary line to obtain the target image. S308-S309 are similar to S103-S104 in FIG. 1 and are not described herein again.
According to the image cutting method and device, after the initial position of the first cutting boundary line is determined by the user, the partial images in the first cutting boundary line are tiled and displayed, so that the partial images in the first cutting boundary line are enlarged, the image area corresponding to the first cutting boundary line can be clearer, the position of the second cutting boundary line can be adjusted more accurately by the user subsequently, and the accuracy of image cutting is improved.
Note that since only tiling is performed in S304, but no cropping operation is performed, it is necessary to lock the position of the target cropping boundary line in the first image, and then crop the first image. Optionally, after the position of the target trimming boundary line in the first image is locked, the content of the first image may be restored and displayed in the image display interface, and the position of the target trimming boundary line is displayed, as shown in fig. 8, fig. 8 illustrates a schematic position diagram of the target trimming boundary line in the first image according to an embodiment of the present invention. The reason why the trimming operation is not performed in S304 is to avoid that the adjustment can be performed by returning to the state where the first trimming boundary line selected by the user is incorrect.
Of course, in other embodiments, after the initial position of the first trimming boundary line is determined, part of the image outside the first trimming boundary line may be trimmed directly, and then the second image may be displayed in a tiled manner.
Further, in some embodiments, after the target trimming boundary line of the partial side is locked, the trimming boundary lines of other sides may be continuously adjusted by repeating the above operations, for example, after the target trimming boundary lines of the left and right sides have been determined, the target trimming boundary lines in the up-down direction are determined by tiling the first image in the up-down direction, as shown in fig. 9, and fig. 9 shows a position diagram of another target trimming boundary line provided by an embodiment of the present invention. In the process of adjusting the trimming boundary lines of the other sides, the determined target trimming boundary line may be displayed in the current first image, and the display mode of the locked target trimming boundary line may be distinguished from the current second trimming boundary line, for example, the second trimming boundary line is a solid line, and the locked target trimming boundary line is a broken line, and the present invention is not limited thereto.
In some other embodiments of the present invention, before S103, S204, or S308, the method may further include:
receiving a third input of the user;
in response to a third input, a target image is displayed within the preview interface.
In this embodiment, after the target trimming boundary line is determined, the trimmed effect may be previewed, where the third input may be an input of clicking a preview button in a screen or a preset preview slide input, and the like. In the case that the user is not satisfied, the user may return to the adjustment interface of the target trimming boundary line through a fourth input, where the fourth input may be an input of clicking a previous button in the screen, and the like.
In still other embodiments of the present invention, the first bending operation comprises: bending any one of four corners of the flexible screen; the first trimming boundary line includes: and the length of the major axis and the length of the minor axis of the oval boundary line are determined according to the curvatures of the flexible screens corresponding to the four corners respectively.
That is, in this embodiment, the first image may be subjected to elliptical cropping, and in other embodiments, the first image may be subjected to circular cropping or the like. That is, when a user bends any one of the four corners of the flexible screen, the effect of elliptical cutting is triggered, as shown in fig. 10, and fig. 10 shows a schematic diagram of an elliptical cutting boundary line provided by an embodiment of the present invention. The mode enriches the image cutting effect and ensures better user experience.
Optionally, in a case where the first trimming boundary line is an elliptical boundary line, the step S202 may include:
taking a tangent plane of the center of the flexible screen as a reference plane, and determining the mapping rate corresponding to each angle according to the included angle formed by the connecting line from each angle to the center and the reference plane; for example, at an included angle of 20 degrees, the refractive index is 10%. The bending degree of each corner may be different, that is, the mapping rate corresponding to each corner may be different.
Taking the product of the reflectivity and the length or width of the flexible screen as the length of the long axis or the short axis corresponding to the angle;
the average of the sum of the lengths of the major axes corresponding to the four corners is taken as the major axis length of the adjusted elliptical boundary line, and the average of the sum of the lengths of the minor axes corresponding to the four corners is taken as the minor axis length of the adjusted elliptical boundary line.
In this embodiment, the reference plane refers to a plane of the flexible screen in an unbent state, and may also be understood as a plane where an unbent portion of the flexible screen is located. The center point of the oval boundary line is the center point of the flexible screen, the target image obtained by final cutting can be symmetrical in the mode, and certainly, in other embodiments, a user can also adjust the center point of the oval boundary line manually. In addition to the center point, the elliptical boundary line is also limited by the lengths of the major axis and the minor axis, in this embodiment, the flexible screen is divided into four parts on average, each corner corresponds to 1/4 flexible screens, the length of the 1/4 flexible screen is 1/2 flexible screen, the width of the 1/4 flexible screen is 1/2 flexible screen, then according to the included angle formed by the connecting line from each corner to the center and the reference plane, the length and width of the 1/4 flexible screen corresponding to the corner after being mapped to the reference plane after being bent can be determined, then the length of the 1/4 flexible screen corresponding to each corner after being mapped to the reference plane is averaged to be used as the major axis of the elliptical boundary line, and the width of the 1/4 flexible screen corresponding to each corner after being mapped to the reference plane is averaged to be used as the minor axis of the elliptical boundary line.
As shown in fig. 10, when the distances between the positions of the angle No. 1 (angle No. 3) and the angle No. 2 (angle No. 4) are shorter, that is, the curvatures of the angle No. 1 (angle No. 3) and the angle No. 2 (angle No. 4) become larger, the minor axis of the ellipse at this time is decreased, and the opposite direction is increased. When the distance between the positions of the No. 1 corner (No. 2 corner) and the No. 3 corner (No. 4 corner) is shorter, namely the curvatures of the No. 1 corner (No. 2 corner) and the No. 3 corner (No. 4 corner) are larger, the major axis of the ellipse is reduced at the moment. Therefore, the position of the oval boundary line can be accurately determined according to the bending condition of the flexible screen.
Based on the embodiment of the image processing method provided by the above embodiment, correspondingly, an embodiment of the present invention further provides an electronic device, where the electronic device includes a flexible screen, and fig. 11 shows a schematic structural diagram of the electronic device provided by the embodiment of the present invention.
