First embodiment
The present embodiment provides a screenshot control method, so as to solve a problem that an existing screenshot scheme requires a user to manually drag a screenshot frame to move so as to select a corresponding screenshot area, which is inconvenient for the user to operate, please refer to fig. 2, where fig. 2 is a basic flowchart of the screenshot control method provided in the present embodiment, and the method includes the following steps:
s201, when receiving a screenshot starting instruction, detecting bending parameters of a flexible screen of the flexible screen terminal.
It should be noted that the present solution is mainly applicable to a flexible screen terminal, that is, a terminal device having a flexible screen, where the flexible display screen may be used to receive a corresponding display instruction issued when a related hardware (e.g., a core processor CPU, a graphics processing unit GPU, etc.) of the terminal executes a related program, and display and process a corresponding image content according to the display instruction, so as to be viewed by a user. Certainly, the flexible screen terminal is not limited to include a flexible display screen, and may further include other hardware devices in order to implement corresponding functions, which please refer to the description of the hardware structure of the terminal in fig. 1, and details are not described herein again. For a common terminal, the scheme is not applicable. The core idea of the scheme is to control the moving and stretching of the screenshot frame based on the bending parameters of the flexible screen of the terminal so as to select the screenshot area.
When the flexible screen terminal receives a screenshot starting instruction, the flexible screen terminal starts to detect the bending parameters of the flexible screen, the detection process can be real-time, the detection on the bending parameters of the flexible screen is closed until the screenshot is completed, and extra power consumption caused by the fact that the terminal continuously opens the detection function when a user does not need to screenshot is avoided.
Bending parameters of the flexible screen of the terminal are detected, wherein the bending parameters include, but are not limited to, a bending direction, a bending degree, a bent portion and the like. It should be appreciated that the manner of detecting the corresponding bending parameter may be any manner, and the present embodiment is not limited thereto. For better understanding, this embodiment specifically provides the following simple description of several detection modes:
for the detection of the bending direction, the bending direction can be divided into two directions of bending to the front side of the flexible screen and bending to the back side of the flexible screen, and certainly the bending direction can also be divided according to other modes, which is not described one by one, when the bending direction is divided into two directions of bending to the front side of the flexible screen and bending to the back side of the flexible screen, detectors such as an acoustic wave sensor or an infrared sensor and the like can be arranged on a terminal of the flexible screen to detect the conditions of the front side and the back side of the flexible screen, taking the infrared sensor as an example, if the area where the front side of the flexible screen is located is blocked, it is indicated that the current bending direction is the bending; and if the shielding of the area where the back surface is located is detected, the current bending direction is bending towards the back surface of the flexible screen. It should be understood that the above examples are for illustrative purposes only and are not to be construed as limiting the present invention. The present solution may also employ any existing means to detect the bending parameter.
For the detection of the bending degree, the bending degree can be represented by the bending angle, and for the detection of the bending angle, referring to fig. 3, a tangent 32 of a detection point 31 of the bending part on a bending curve is detected, and an included angle formed by the tangent 32 and an unbent part 33 is detected to obtain the bending angle alpha. Specifically, a gravity sensor or an orientation sensor may be disposed on a partial area or a whole area of the flexible display screen to detect a bending condition or a bending path of a relevant area of the flexible display screen, so that a bending included angle formed between the detection point 31 and the unbent portion 33 can be obtained. The bending angle may range from 0 ° to 180 °, it being understood that when 180 °, i.e. bent parallel to the front or back of the flexible screen; when the bending angle is 0 °, that is, the flexible display screen is not bent, the flexible display screen is in a flat state.
It should be understood that the above-mentioned manner of detecting the bending angle of the flexible display screen is only an example, and of course, any manner may be adopted as long as the bending degree can be detected, and the present embodiment does not limit this.
The degree of curvature may also be characterized by a curvature, and it should be understood that the curvature refers to a rotation rate of a tangential direction angle of a certain point on a curve to an arc length, and when the arc length is constant, the larger the tangential direction angle of rotation is, the larger the curvature is, indicating the degree of curvature is, and the smaller the tangential direction angle of rotation is, the smaller the curvature is, indicating the degree of curvature is. For the detection of the bending curvature, the flexible screen terminal can realize the calculation of the bending curvature by detecting the length of the bending arc and the rotation angle, and can also calculate the curvature by detecting the pressure of each point of the bending part, the larger the pressure is usually born, the larger the bending degree of the point is, the larger the curvature is, and the corresponding bending curvature is obtained through the preset corresponding relation between the pressure and the bending curvature, so that the size of the cutout frame is controlled and changed.
S202, controlling the movement and the expansion of the screenshot frame according to the bending parameters to select a corresponding screenshot area.
And controlling the moving and stretching of the screenshot frame in real time based on the bending parameters obtained by current detection so as to select a corresponding screenshot area.
For example, when the detected bending parameter is a bending direction, the extending direction of the capture frame may be controlled according to the bending direction, that is, the capture frame is controlled to be stretched or compressed toward the extending direction, so as to change the size of the capture frame. Specifically, referring to fig. 4, a first correspondence table is pre-stored in the flexible screen terminal, and a first target extending direction corresponding to the detected bending direction is selected, so as to control the cutout frame to stretch or compress along the first target extending direction; the first mapping table is a mapping table of the bending direction and the extending direction of the cutout frame, and can be specifically shown in the following table 1:
TABLE 1
| Direction of bending | The extending direction of the frame-cutting frame |
| Bending to the front of the flexible screen | Extend downwards |
| Bending to the back of the flexible screen | Extend to the right |
The description is made here by way of example: after receiving a screenshot command issued by a user, assuming that the bending direction of the flexible screen is detected to be bending towards the front of the flexible screen, at this time, the flexible screen terminal selects a first target extending direction "extending downwards" corresponding to the bending direction "bending towards the front of the flexible screen" according to a first pre-stored corresponding relation table (here, it is assumed to be table 1), so as to control the screenshot frame 41 to stretch downwards and move, so as to expand the frame selection area of the screenshot frame.
Or, when the detected bending parameter is a bending area, the flexible screen terminal may control the movement and the expansion of the screenshot frame according to the detected bending area to select a corresponding screenshot area. For example, the flexible screen terminal may store a correspondence table between the bending area and the extending direction of the flexible screen in advance, and the correspondence table may be shown in table 2 below:
TABLE 2
| Bending zone | The extending direction of the frame-cutting frame |
| Bending zone 1 | Extend upwards |
| Bending zone 2 | Extend downwards |
| Bending zone 3 | Extend leftwards |
| Bending zone 4 | Extend to the right |
Referring to fig. 5, the diagram on the left side shows that when the flexible screen terminal receives a screenshot command issued by a user, a preset screenshot frame 51 is generated, and the size and shape of the preset screenshot frame 51 can be flexibly set according to the actual requirements of the user; and detecting the bending area of the flexible screen, if the currently detected bending area is a preset area at the lower side of the flexible screen, controlling the screen capture frame 51 to stretch and move along the display area at the lower part of the terminal, and if the screen capture frame is stretched and moved at the right side 52 in fig. 5, changing and controlling the movement of the screen capture frame, changing the size of the screen capture frame, enabling the area selected by the screen capture frame to meet the screen capture requirement of a user, and enabling the whole screen capture process to be convenient and flexible without the user manually dragging the screen capture frame.
It should be noted that the bending area can be flexibly set, for example, referring to fig. 6, the left side partial area 61 of the flexible screen is taken as a first area, the right side partial area 62 of the flexible screen is taken as a second area, the upper side partial area 63 of the flexible screen is taken as a third area, and the lower side partial area 64 of the flexible screen is taken as a fourth area.
Or, the bending parameter may also be a bending angle, and the flexible screen terminal determines an extending direction corresponding to the bending angle according to the detected bending angle, so as to control the movement and stretching of the cutout frame.
It should be understood that, in practical applications, in order to better meet the actual use requirements of users, at least two of the bending parameters include a bending direction, a bending area, and a bending angle, so as to implement the control of the moving and stretching of the screenshot frame. For example, the extending direction of the cutout frame is controlled by the bending area and the bending direction together to change the selected area of the cutout frame, specifically, see the following example:
for convenience of description, the bending region and the bending direction are collectively referred to as a comprehensive bending parameter, that is, the comprehensive bending parameter includes both the bending region and the bending direction. When a screenshot command issued by a user is received, detecting a comprehensive bending parameter of the flexible screen, selecting a second target extension direction corresponding to the currently detected comprehensive bending parameter according to a second corresponding relation table between the currently detected comprehensive bending parameter and a comprehensive bending parameter preset by the flexible screen terminal and the extension direction of the screenshot frame, and controlling the screenshot frame to extend along the second target extension direction. The second correspondence table may be referred to as the following table 3:
TABLE 3
| Comprehensive bending parameter | The extending direction of the frame-cutting frame |
| Bending region 1, bending direction a | Extend upwards |
| Bending region 1, bending direction b | Extend downwards |
| Bending zone 2, bending direction a | Extend leftwards |
| Bending region 2, bending direction b | Extend to the right |
For example, if the currently detected comprehensive bending parameter is "bending area 1, bending direction a", the flexible screen terminal will control the cutout frame to extend upward, and the process of specifically controlling the cutout frame to extend is not described herein again.
It should be understood that the scheme is not limited to screenshot in the currently visible display area of the flexible screen, but the scheme is also applicable to long screenshot, and the long screenshot is realized by extending the screenshot frame to a pull-down area or a pull-right area which is not visible on the current screen through movement of the screenshot frame.
And S203, when receiving a screenshot finishing instruction, selecting the currently selected screenshot area of the screenshot box as a target screenshot area, and controlling to screenshot the image in the target screenshot area.
When a user enables a screenshot frame to select a screenshot requirement expected by the user by bending the flexible screen, a screenshot completing instruction is issued to the flexible screen terminal, and the specific manner for issuing the screenshot completing instruction can be any conventional manner without limitation. At this time, when the flexible screen terminal receives the instruction for completing screenshot, the current screenshot area selected by the screenshot selecting frame is used as the target screenshot area, and screenshot of the image in the target screenshot area is controlled to generate a screenshot image. Therefore, the screenshot process is achieved through the bending parameters of the flexible screen, the user does not need to manually pull the screenshot frame in the screenshot area selection process, the movement stretching of the screenshot frame is achieved through the bending flexible screen, the operation is convenient and rapid, and misoperation cannot be easily caused.
Second embodiment
The embodiment provides a screenshot control method, which is different from the first embodiment in that the screenshot frame is accurately controlled to move and stretch by simultaneously combining a plurality of bending parameters, the size of the screenshot frame is adjusted, actual use requirements of a user are met, relatively more complex screenshot requirements are met, and user experience is improved. Referring to fig. 7, fig. 7 is a schematic flowchart of a screenshot control method according to a second embodiment of the present invention, where the screenshot control method includes the following steps:
s701, detecting the bending parameters of the flexible screen in real time when a long screenshot command is received; wherein the bending parameters include a bending area, a bending direction, and a bending angle.
The screenshot control scheme provided by the embodiment can be suitable for common screenshots (non-long screenshots) and long screenshots. When the flexible screen terminal receives the long screenshot command, the flexible screen terminal starts to detect bending parameters of the flexible screen, namely a bending area, a bending direction and a bending angle. The specific method for detecting the bending parameter may be any conventional method, or the detection method described in the first embodiment, which is not described herein again.
And S702, determining a corresponding target screenshot frame according to the currently detected bending area.
In this embodiment, the screenshot frame may be a rectangular screenshot frame, and includes four frame sides, which may be controlled by the scheme provided in this embodiment, so that the four frame sides may move along four directions of the flexible screen, and the moving speed of the flexible screen.
The determination of the corresponding target screenshot frame according to the bending area may be specifically implemented according to a third correspondence table of the bending area and the screenshot frame preset by the flexible screen terminal, where the third correspondence table may be as shown in table 4 below:
TABLE 4
| Bending zone | Frame edge of screenshot |
| Left part area of flexible screen | Left side frame edge of cutout frame |
| Right partial area of flexible screen | Right frame edge of cutout frame |
| Flexible screen upper side partial area | Upper frame edge of picture-cutting frame |
| Lower partial area of flexible screen | Lower side frame edge of cutout frame |
The upper, lower, left and right partial areas of the flexible screen can be continuously referred to as shown in fig. 6, and the screenshot frame is rectangular, so that four frame edges, namely an upper frame edge, a lower frame edge, a left frame edge and a right frame edge, exist; for example, if the current bending area belongs to the left partial area of the flexible screen, the target screenshot frame edge is the left frame edge of the screenshot frame, so that the left frame edge is controlled to extend correspondingly. The specific extension method also needs to be performed in combination with the direction and rate of extension, while the direction of extension (i.e., the target extension direction) needs to be determined based on the bending direction, and the rate of extension (i.e., the target extension rate) needs to be determined based on the bending angle.
And S703, determining the target extension direction corresponding to the frame edge of the target screenshot according to the currently detected bending direction.
After the frame edge of the target screenshot is determined, the target extending direction of the frame edge of the target screenshot is also determined according to the bending direction, which is specifically shown in the following table 5:
TABLE 5
In table 5, that is, the target extending direction of the frame border of the target screenshot is further determined according to the bending finding, and after the frame border of the target screenshot is determined to be the left frame border according to the bending region (for example, the left partial region), the target extending direction of the left frame border may be determined to be extending rightward according to the bending direction (for example, bending toward the front of the flexible screen).
And S704, determining the target extension rate of the target screenshot frame moving along the target extension direction according to the currently detected bending angle.
According to the scheme, the target extension rate of the target screenshot frame moving along the target extension direction is determined according to the bending angle, the extension rate can be controlled, and accurate screenshot is facilitated.
For example, it is also determined that the target screenshot frame edge is the lower frame edge of the screenshot frame according to the bending area (assumed as the lower partial area) and the bending direction (bending toward the back of the flexible screen), and the target extending direction of the lower frame edge is downward extension, and at this time, it is further required to determine the target extending rate of the lower frame edge extending downward according to the detected bending angle, specifically, according to a fourth corresponding relation table between the bending angle and the extending rate of the screenshot frame, as shown in table 6 below:
TABLE 6
| Bending angle | Rate of elongation |
| 0°～30° | V1 |
| 30°～60° | V2 |
| ＞60° | V3 |
If the detected bending angle is 20 °, according to the fourth corresponding relation table of the preset bending angle and the extension rate, the target extension rate can be determined to be V1, and the bending area (assumed as the lower partial area) and the bending direction (bending towards the back of the flexible screen) are combined, so that the lower frame edge of the cutout frame is determined to extend downwards at the rate of V1, and the current bending parameters can be adjusted in real time, so that the moving extension of the cutout frame can be well controlled.
It should be understood that the fourth corresponding relationship between the bending angle and the extension rate can be flexibly set according to actual situations, and is not limited to the example shown in table 6, for example, the bending angle can be divided into two types of angles from 0 ° to 45 ° and more than 45 °, and the four types of angles correspond to the extension rates v1 and v2, respectively.
S705, controlling the extension of the frame edge of the target screenshot according to the target extension direction and the target extension rate.
Referring to fig. 8, according to the bending area (assumed as the lower partial area), the bending direction (bending toward the back of the flexible screen), and the bending angle (20 °), it is determined that the lower frame edge 81 of the screenshot frame (i.e. the target frame edge) extends downward (i.e. the target extending direction) at a V1 rate (i.e. the target extending rate), and when the flexible screen returns to the flat state (i.e. the user stops bending the flexible screen), the screenshot frame is controlled to stop, and at this time, the lower frame edge stops at the position 82.
And S706, when the instruction of finishing the long screenshot is received, selecting the currently selected screenshot area of the screenshot box as a target screenshot area, and controlling to screenshot the image in the target screenshot area to obtain a target screenshot image.
And S707, controlling the target screenshot picture to be displayed in a full screen or in a small window on the flexible screen.
The target screenshot picture obtained by screenshot the image in the target screenshot area can also be directly displayed on the flexible screen in a full screen mode or a small window mode for a user to view and process.
