Description

TECHNICAL FIELD

[0001] The present application relates to the handwriting field, and particularly relates to a method and device for beautifying ink screen handwriting strokes, an electronic device and a storage medium. BACKGROUND

[0002] With the development and popularity of touch screen technology, handwriting input is also more and more widely used in electronic devices such as mobile phone terminals, tablet computers, handwriting boards and smart televisions. Compared with keyboard input, handwriting input has the advantages of being more intuitive, convenient and user-friendly. However, if the electronic device directly displays the strokes corresponding to the handwriting input report point data, the strokes appear to be rigid and lack of aesthetic sense, and the user experience is poor. In order to improve the user experience, in recent years, various methods for beautifying the handwriting in the style of calligraphy based on user input have appeared. The existing handwriting beautifying methods generally beautify the handwriting strokes, and some of the beautifying methods are performed after a character is written by the user, and some of the beautifying methods are performed after a stroke is written by the user. These methods have achieved some beautifying effects, but because there is a certain delay compared with the user input, the user cannot obtain timely feedback and good user experience. In particular, when handwriting is input on an ink screen, the display delay problem is more obvious, because compared with the liquid crystal display screen of a general electronic device, the display frame rate of the ink screen is much slower, and if the beautifying is performed after a character or a stroke is written by the user, the display delay will be more obvious.

[0024] The beautifying method provided by the application examples can be used on the ink screen, especially on the electronic device with the ink screen. The electronic device can be a tablet computer, a mobile phone, an electronic reader, a personal digital assistant (PDA) and the like based on the ink screen. Specifically, the electronic device can include an ink screen, a communication module, a digital signal processor, an image processing module, a microcontroller, a screen driving module, a timing control circuit, and a power supply control circuit.

[0025] The application examples are described in detail below.

[0026] Figure 1The flowchart of the embodiment one of the ink screen handwriting stroke beautifying method provided in the application can be executed by a display device, which can be realized by hardware and / or software and integrated in an ink screen.

[0027] The ink screen handwriting stroke beautifying method executed by a display device is described below. Referring to Figure 1 A method for beautifying ink screen handwriting strokes, the method comprising: In step S10, handwriting stroke report point data input by a handwriting pen is acquired.

[0028] After the ink screen enters a handwriting mode, a user inputs handwriting strokes by a handwriting pen, and handwriting stroke report point data is formed on the ink screen by the handwriting pen input. It can be understood that the report point data herein refers to data of a series of continuous or discontinuous handwriting report points drawn by the user on the ink screen, and the report point data includes but is not limited to coordinate information, time information, handwriting type and handwriting width, handwriting pressure information and handwriting tilt information, etc. The report point data can be acquired by real-time reading by a handwriting pen sensing device, or by reading touch point coordinates by the ink screen, which is not limited herein.

[0029] In addition, the handwriting pressure information and the handwriting tilt information can be acquired based on the handwriting pen. For example, the handwriting pen feeds back corresponding handwriting pressure information and handwriting tilt information to the ink screen in real time based on the tip pressure and the body tilt angle detected by the handwriting pen; or the ink screen detects the tip pressure and the body tilt angle of the handwriting pen to obtain the handwriting pressure information and the handwriting tilt information. Meanwhile, the ink screen determines report point coordinates and report point time based on handwriting operation, and determines handwriting input information based on the report point coordinates and the report point time, the handwriting pressure information and / or the handwriting tilt information. The handwriting type and the handwriting width are pre-set or set by the user in the ink screen.

[0030] In step S20, a first handwriting stroke is generated according to the handwriting stroke report point data.

[0031] Specifically, the handwriting stroke report point data is rendered and drawn to generate the first handwriting stroke.

[0032] In step S30, the first handwriting stroke is driven and displayed on the ink screen.

[0033] In the embodiment of the application, when the handwriting stroke input has not ended, handwriting stroke report point data input by the handwriting pen is continuously acquired according to the frequency of acquiring the report point data by the ink screen, and the first handwriting stroke is generated according to the handwriting stroke report point data, and the first handwriting stroke is continuously driven and displayed on the ink screen.

[0034] In step S40, the first handwriting stroke is beautified according to a first preset rule to obtain a second handwriting stroke, and a pixel area corresponding to the second handwriting stroke covers a pixel area corresponding to the first handwriting stroke.

[0035] In the application, the first handwriting stroke is taken as a skeleton, and the first handwriting stroke is beautified on the basis of the first handwriting stroke to obtain the second handwriting stroke. Moreover, a pixel area corresponding to the second handwriting stroke covers a pixel area corresponding to the first handwriting stroke. Therefore, the pen width of the first handwriting stroke is usually set as a standard width, and then the first handwriting stroke is beautified according to the first preset rule, for example, the first handwriting stroke is formed to have a thin starting end, a thick middle part and a thin ending end, so as to obtain the second handwriting stroke. In this way, the second handwriting stroke has artistic beauty, and the user experience is better.

[0036] In step S50, the second handwriting stroke is driven and displayed on the ink screen.

[0037] That is, the first handwriting stroke is driven and displayed on the ink screen, and the first handwriting stroke is beautified according to the first preset rule to obtain the second handwriting stroke. Then, the second handwriting stroke is driven and displayed on the ink screen. In this way, the handwriting stroke can be beautified and displayed during handwriting, and the handwriting stroke does not need to be beautified and displayed after being completed. Therefore, the handwriting beautification and display effect of the ink screen is obviously improved.

[0038] Please refer to Figure 2 , Figure 2 The flow chart of the embodiment one of step S50 of the handwriting stroke beautification method of the ink screen provided by the application is provided. Further, on the basis of the beautification method provided by the application, Figure 1 The step of driving and displaying the second handwriting stroke on the ink screen includes: In step S51, the area of the second handwriting stroke that overlaps the first handwriting stroke is removed to obtain a third handwriting stroke. In step S52, the third handwriting stroke is driven and displayed on the ink screen.

[0039] Since the pixel area corresponding to the second handwriting stroke covers the pixel area corresponding to the first handwriting stroke, the second handwriting stroke and the first handwriting stroke have an overlapping area. When actually displaying, the area of the second handwriting stroke overlapping with the first handwriting stroke has been refreshed in the display of the first handwriting stroke, so when displaying the second handwriting stroke, only the area of the second handwriting stroke not overlapping with the first handwriting stroke, i.e. the third handwriting stroke, can be refreshed, or the second handwriting stroke can be refreshed once. In the embodiment of the present application, the third handwriting stroke is obtained by removing the area of the second handwriting stroke overlapping with the first handwriting stroke, and then the third handwriting stroke is driven and displayed on the ink screen, so that the second handwriting stroke is completely displayed, which is beneficial to reduce the display energy consumption and improve the processing performance.

[0040] Further, refer to Figure 3 and Figure 4 , Figure 3 the flowchart of step S30 of the beautifying method of the handwriting stroke of the ink screen provided in the present application, Figure 4 the flowchart of the second embodiment of step S30 of the beautifying method of the handwriting stroke of the ink screen provided in the present application. In Figure 1 the beautifying method provided, in an embodiment of the present application, the step of driving and displaying the first handwriting stroke on the ink screen comprises: step S31, obtaining a first driving waveform of the first handwriting stroke according to a first refresh mode; step S32, driving the ink screen to display the first handwriting stroke according to the first driving waveform; the step of driving and displaying the second handwriting stroke on the ink screen comprises: step S53, obtaining a second driving waveform of the second handwriting stroke according to a second refresh mode; step S54, driving the ink screen to display the second handwriting stroke according to the second driving waveform; the first refresh mode is different from the second refresh mode, and the refresh time length of the first refresh mode is less than the refresh time length of the second refresh mode.

[0041] That is, in the embodiment of the present application, the first handwriting stroke and the second handwriting stroke are displayed by using different refresh modes respectively, that is, a first driving waveform of the first handwriting stroke is obtained according to a first refresh mode, and the ink screen is driven according to the first driving waveform to display the first handwriting stroke; then a second driving waveform of the second handwriting stroke is obtained according to a second refresh mode, and the ink screen is driven according to the second driving waveform to display the second handwriting stroke. Moreover, the refresh time length of the first refresh mode is less than that of the second refresh mode, because when the first handwriting stroke is displayed, the first handwriting stroke needs to be displayed quickly, so the first refresh mode is used to drive the first handwriting stroke to reduce the delay of handwriting stroke display; and when the second handwriting stroke is displayed, the display quality needs to be emphasized, so the second refresh mode is used to drive the second handwriting stroke to improve the display quality of handwriting stroke.

[0042] Further, in the embodiment of the present application, the first refresh mode is a DU refresh mode, and the second refresh mode is a GU refresh mode. Of course, it is easily thought that the first refresh mode and the second refresh mode can also be other refresh modes, as long as the refresh time length of the first refresh mode is less than that of the second refresh mode.

[0043] The refresh modes of the ink screen include: an A2 refresh mode, a DU refresh mode, a GC refresh mode (including a GC4 refresh mode, a GC8 refresh mode and a GC16 refresh mode), a GU refresh mode, a GL refresh mode and a GLR refresh mode. Specifically: The A2 refresh mode: the originally displayed gray scale content is presented in black and white to reduce the time and power consumption caused by rendering gray scale, and the refresh speed is the fastest.

[0044] The DU refresh mode: the originally displayed gray scale content is presented in black and white, and the refresh speed is only second to the A2 refresh mode, but the ghosting is less than that of the A2 refresh mode.

[0045] The GC refresh mode: all pixels are re-output, and a screen clearing operation is performed before output, which can be subdivided into a GC4 refresh mode, a GC8 refresh mode and a GC16 refresh mode, which respectively represent that 4, 8 and 16 gray scales can be supported, and the refresh speed is the slowest, but the ghosting is the least. The GC refresh mode is also called full screen refresh, that is, the entire page is refreshed once, regardless of whether the gray scale of the same pixel changes before and after.

[0046] GU refresh mode: no clearing operation before data output, directly outputting pixels changed from the last output, including GU8 refresh mode, GU16 refresh mode, etc., representing support for 8 and 16 gray scales respectively, which is slower than A2 refresh mode and DU refresh mode, but faster than GC refresh mode. GU refresh mode is also called partial refresh, which is acceptable in terms of speed and smoothness of page changes.

[0047] GL refresh mode: no clearing operation before data output, generally GL16 refresh mode, that is, supporting 16 gray scales, which is slower than A2 refresh mode and DU refresh mode, but faster than GC refresh mode. GL refresh mode is also a partial refresh.

[0048] GLR refresh mode: also known as "regal", generally GLR16 refresh mode, that is, supporting 16 gray scales, similar to partial refresh, the refresh mode depends on the difference between the previous and subsequent pictures, and the special feature is that if the previous and subsequent pictures are black to black, it will go through black-white-black flashing. The refresh speed is close to the aforementioned partial refresh mode, and the residual image is less.

[0049] Please refer to Figure 5 , Figure 5 The flowchart of step S40 of the ink screen handwriting stroke beautification method provided in the present application. Further, on the basis of the beautification method provided in Figure 1 In an embodiment of the present application, the step of beautifying the first handwriting stroke according to the first preset rule to obtain a second handwriting stroke includes: Step S41, divide the first handwriting stroke into a head section, a middle section and a tail section, obtain the point number or length of the head section according to the speed of the handwriting pen, obtain the point number or length of the tail section according to the current speed of the pen nib outside the head section area, and obtain the point number of the middle section by subtracting the point number of the head section and the point number of the tail section from the point number of the first handwriting stroke, or obtain the length of the middle section by subtracting the length of the head section and the length of the tail section from the length of the first handwriting stroke. Step S42, obtaining a first beautifying width of a start end of the head section, a first beautifying width of an end of the head section, a first beautifying width of a start end of the tail section, and a first beautifying width of an end of the tail section, wherein the first beautifying width of the start end of the head section is less than or equal to the first beautifying width of the end of the head section, the first beautifying width of the section between the start end of the head section and the end of the head section is smoothly changed, the first beautifying width of the end of the head section, the first beautifying width of the middle section, and the first beautifying width of the start end of the tail section are the same, the first beautifying width of the start end of the tail section is greater than or equal to the first beautifying width of the end of the tail section, and the first beautifying width of the section between the start end of the tail section and the end of the tail section is smoothly changed. Step S43, performing shape beautification on the first handwriting stroke according to the first beautifying width of the start end of the head section, the first beautifying width of the end of the head section, the first beautifying width of the start end of the tail section, and the first beautifying width of the end of the tail section to obtain a second handwriting stroke.

[0050] Specifically, first, the first handwriting stroke is divided into a head section, a middle section, and a tail section, then the number of points or length of the head section is obtained according to the speed of the handwriting pen when the handwriting pen starts to write, that is, when the handwriting pen starts to write, the speed of the handwriting pen can be obtained, then the number of points or length of the tail section is obtained according to the current speed of the pen nib outside the head section area when the handwriting pen writes the middle section and the tail section, so the number of points or length of the tail section is obtained according to the current speed of the pen nib, and the change of the current speed of the pen nib corresponds to the change of the number of points or length of the tail section; finally, the number of points of the middle section is obtained by subtracting the number of points of the head section and the number of points of the tail section from the number of points of the first handwriting stroke, or the length of the middle section is obtained by subtracting the length of the head section and the length of the tail section from the length of the first handwriting stroke. That is, the number of points or length of the middle section is obtained by subtracting the number of points or length of the head section and the number of points or length of the tail section from the number of points or length of the first handwriting stroke in turn after the number of points or length of the head section and the number of points or length of the tail section are determined. When the result of subtracting the number of points or length of the head section and the number of points or length of the tail section from the number of points or length of the first handwriting stroke in turn is zero or negative, it represents that the number of points or length of the middle section is zero, and at this time, the middle section of the first handwriting stroke does not exist; when the result of subtracting the number of points or length of the head section and the number of points or length of the tail section from the number of points or length of the first handwriting stroke in turn is positive, the middle section of the first handwriting stroke is displayed.

[0051] Secondly, a first beautifying width of the start end of the head section, a first beautifying width of the end of the head section, a first beautifying width of the start end of the tail section and a first beautifying width of the end of the tail section are obtained, wherein the first beautifying width of the start end of the head section is less than or equal to the first beautifying width of the end of the head section, the first beautifying width of the section between the start end of the head section and the end of the head section is changed smoothly, the first beautifying width of the end of the head section, the first beautifying width of the middle section and the first beautifying width of the start end of the tail section are the same, the first beautifying width of the start end of the tail section is greater than or equal to the first beautifying width of the end of the tail section, and the first beautifying width of the section between the start end of the tail section and the end of the tail section is changed smoothly. The first beautifying width of the section between the start end of the head section and the end of the head section can be changed linearly or curvilinearly, and the first beautifying width of the section between the start end of the tail section and the end of the tail section can be changed linearly or curvilinearly.

[0052] Finally, the first handwriting stroke is beautified according to the first beautifying width of the start end of the head section, the first beautifying width of the end of the head section, the first beautifying width of the start end of the tail section and the first beautifying width of the end of the tail section to obtain a second handwriting stroke.

[0053] Further, in an embodiment of the present application, the first beautifying width of the start end of the head section, the first beautifying width of the end of the head section, the first beautifying width of the start end of the tail section and the first beautifying width of the end of the tail section are all preset widths. At this time, the first handwriting stroke is beautified according to the head section, the middle section and the tail section of the first handwriting stroke to obtain a second handwriting stroke.

[0054] Please refer to Figure 6 , Figure 6 The flow chart of step S42 of the method for beautifying the ink screen handwriting stroke provided by the present application. Further, in Figure 5 the method provided by the present application, the step of obtaining the first beautifying width of the start end of the head section, the first beautifying width of the end of the head section, the first beautifying width of the start end of the tail section and the first beautifying width of the end of the tail section comprises: Step S421, obtaining the first beautifying width of the start end of the head section and the first beautifying width of the end of the head section according to the speed of the handwriting pen when landing; Step S422, obtaining the first beautifying width of the end of the tail section according to the current speed of the nib of the handwriting pen outside the head section area.

[0055] That is, in the embodiment of the present application, the first beautifying width of the start end of the head section and the first beautifying width of the end of the head section are obtained according to the pen-down speed of the handwriting pen, and the first beautifying width of the end of the tail section is obtained according to the current pen tip speed of the handwriting pen outside the head section area. At this time, the first mapping relationship of the pen-down speed and the first beautifying width of the start end of the head section and the first beautifying width of the end of the head section, and the second mapping relationship of the current pen tip speed of the handwriting pen outside the head section area and the first beautifying width of the end of the tail section can be preset, the first beautifying width of the start end of the head section and the first beautifying width of the end of the head section can be obtained by querying the first mapping relationship according to the pen-down speed, and the first beautifying width of the end of the tail section can be obtained by querying the second mapping relationship according to the current pen tip speed of the handwriting pen outside the head section area.

[0056] Please refer to Figure 7 , Figure 7 The flow chart of step S41 of the ink screen handwriting stroke beautifying method provided by the present application. Further, on the basis of the beautifying method provided by the present application, in an embodiment of the present application, the step of obtaining the point number or length of the tail section according to the current pen tip speed of the handwriting pen outside the head section area comprises: Figure 5 Step S411, obtaining a first point number or a first length according to the current pen tip speed of the handwriting pen outside the head section area; Step S412, judging whether the point number of the first handwriting stroke is greater than the sum of the point number of the head section and the first point number, or judging whether the length of the first handwriting stroke is greater than the sum of the length of the head section and the first length; Step S413, if yes, the point number of the tail section is the first point number, and the length of the tail section is the first length; Step S414, if no, the point number of the tail section is obtained by subtracting the point number of the head section from the point number of the first handwriting stroke, and the length of the tail section is obtained by subtracting the length of the head section from the length of the first handwriting stroke.

[0057] ​The first point number or the first length is obtained according to the current stylus tip speed outside the head section area. A mapping relationship between the current stylus tip speed and the point number or the length can be preset. Then, when the current stylus tip speed outside the head section area is obtained, the first point number or the first length corresponding to the current stylus tip speed can be obtained on the mapping relationship. Then, it is judged whether the point number of the first handwriting stroke is greater than the sum of the point number of the head section and the first point number, or whether the length of the first handwriting stroke is greater than the sum of the length of the head section and the first length. When the point number of the first handwriting stroke is greater than the sum of the point number of the head section and the first point number, or the length of the first handwriting stroke is greater than the sum of the length of the head section and the first length, the point number of the tail section is the first point number, and the length of the tail section is the first length.

[0058] When the point number of the first handwriting stroke is less than or equal to the sum of the point number of the head section and the first point number, or the length of the first handwriting stroke is less than or equal to the sum of the length of the head section and the first length, it is represented that the middle section of the first handwriting stroke does not exist at this time. The point number of the tail section is obtained by subtracting the point number of the head section from the point number of the first handwriting stroke, and the length of the tail section is obtained by subtracting the length of the head section from the length of the first handwriting stroke.

[0059] Please refer to Figure 8 , Figure 8 The flow chart of Embodiment Two of the handwriting stroke beautifying method of the ink screen provided in the present application is provided. Further, on the basis of the beautifying method provided in the present application, in an embodiment of the present application, the beautifying method further comprises: Figure 1 Step S60, detecting an end signal of handwriting stroke input; Step S70, when the end signal of handwriting stroke input is detected, obtaining the point number of the handwriting stroke or the length of the handwriting stroke according to the latest handwriting stroke point data; Step S80, judging whether the point number of the handwriting stroke is greater than the quantity threshold value or judging whether the length of the handwriting stroke is greater than the length threshold value; Step S90, if not, performing shape beautification on the latest handwriting stroke point data according to a second preset rule to obtain a fourth handwriting stroke; Step SA0, obtaining a fourth driving waveform according to the fourth handwriting stroke; Step SB0, driving the ink screen according to the fourth driving waveform to display the fourth handwriting stroke.

[0060] ​That is, the application detects an end signal of the handwriting pen stroke input, wherein in an embodiment of the application, the end signal includes pen-up information of the handwriting pen, that is, when the pen-up information of the handwriting pen is detected, it is judged that the handwriting pen stroke input has ended. When the end signal of the handwriting pen stroke input is detected, the number of points of the handwriting pen stroke or the length of the handwriting pen stroke is obtained according to the latest handwriting pen stroke point reporting data, and then it is judged whether the number of points of the handwriting pen stroke is greater than the number threshold or whether the length of the handwriting pen stroke is greater than the length threshold, that is, if the number of points of the handwriting pen stroke is greater than the number threshold or the length of the handwriting pen stroke is greater than the length threshold, it indicates that the number of points of the handwriting pen stroke or the length of the handwriting pen stroke is large enough to form a complete stroke, so the second handwriting pen stroke is a complete stroke and does not need to be re-beautified.

[0061] If the number of points of the handwriting pen stroke is less than or equal to the number threshold or the length of the handwriting pen stroke is less than or equal to the length threshold, it indicates that the number of points of the handwriting pen stroke or the length of the handwriting pen stroke is small, and the second handwriting pen stroke is not a complete stroke, for example, after the handwriting pen stroke input ends, the second handwriting pen stroke displayed on the ink screen only has a head segment and a tail segment and does not have a middle segment, or the second handwriting pen stroke displayed on the ink screen only has a head segment and does not have a tail segment and a middle segment, so the fourth handwriting pen stroke is obtained by re-beautifying the shape of the latest handwriting pen stroke point reporting data according to a second preset rule, and then a fourth driving waveform is obtained according to the fourth handwriting pen stroke; and the fourth handwriting pen stroke is displayed on the ink screen according to the fourth driving waveform. According to the second preset rule, the fourth handwriting pen stroke is obtained by re-beautifying the shape of the latest handwriting pen stroke point reporting data, so that the handwriting pen stroke beautification shape can be adjusted again according to the handwriting result, which is beneficial to improve the beauty of the handwriting pen stroke and the user experience.

[0062] Please refer to Figure 9 , Figure 9 The flowchart of step S90 of the handwriting pen stroke beautification method provided by the application is provided. Further, on the basis of the beautification method provided by Figure 8 In an embodiment of the application, the step of obtaining the fourth handwriting pen stroke by beautifying the shape of the latest handwriting pen stroke point reporting data according to a second preset rule includes: Step S91, dividing the latest handwriting pen stroke point reporting data into a head segment, a middle segment and a tail segment according to a preset ratio; In step S92, a second beautifying width of the start end of the head section, a second beautifying width of the end end of the head section, a second beautifying width of the start end of the tail section, and a second beautifying width of the end end of the tail section are obtained, the second beautifying width of the start end of the head section is less than the second beautifying width of the end end of the head section, the second beautifying width of the section between the start end of the head section and the end end of the head section is smoothly changed, the second beautifying width of the end end of the head section, the second beautifying width of the middle section, and the second beautifying width of the start end of the tail section are the same, the second beautifying width of the start end of the tail section is greater than the second beautifying width of the end end of the tail section, and the second beautifying width of the section between the start end of the tail section and the end end of the tail section is smoothly changed. In step S93, the latest hand-written stroke report point data is beautified in shape according to the second beautifying width of the start end of the head section, the second beautifying width of the end end of the head section, the second beautifying width of the start end of the tail section, and the second beautifying width of the end end of the tail section to obtain a fourth hand-written stroke.

[0063] That is, in the embodiment of the present application, when the report point number of the hand-written stroke is less than or equal to the number threshold value or the length of the hand-written stroke is less than or equal to the length threshold value, the latest hand-written stroke report point data is divided into a head section, a middle section, and a tail section according to a preset ratio, then a second beautifying width of the start end of the head section, a second beautifying width of the end end of the head section, a second beautifying width of the start end of the tail section, and a second beautifying width of the end end of the tail section are obtained, and then the latest hand-written stroke report point data is beautified in shape according to the second beautifying width of the start end of the head section, the second beautifying width of the end end of the head section, the second beautifying width of the start end of the tail section, and the second beautifying width of the end end of the tail section to obtain a fourth hand-written stroke. The second beautifying width of the section between the start end of the head section and the end end of the head section can be linearly smoothly changed or can be curvedly smoothly changed, and the second beautifying width of the section between the start end of the tail section and the end end of the tail section can be linearly smoothly changed or can be curvedly smoothly changed.

[0064] In an embodiment of the present application, the ratio of the head section, the middle section, and the tail section is 1:0:0, that is, only the head section is displayed without the middle section and the tail section. Of course, it is easily thought that the ratio of the head section, the middle section, and the tail section can also be other values, but the ratio value of the head section is not zero.

[0065] In addition, in another embodiment of the present application, the preset ratio of the head section, the middle section, and the tail section can be obtained according to one of a pen-down speed, a pen-up speed, and an average speed of a hand-writing pen in a hand-writing process.

[0066] In yet another embodiment of the present application, the preset proportions of the head section, the middle section and the tail section can be calculated according to the pen-down speed, the pen-up speed and the average speed of the stylus during the handwriting process.

[0067] Further, based on the beautifying method provided, Figure 9 In an embodiment of the present application, based on the beautifying method provided, the step of dividing the latest stylus stroke report point data into a head section, a middle section and a tail section according to preset proportions comprises: dividing the report point number of the latest stylus stroke report point data according to preset proportions so as to divide the latest stylus stroke report point data into a head section, a middle section and a tail section; or dividing the length corresponding to the latest stylus stroke report point data according to preset proportions so as to divide the latest stylus stroke report point data into a head section, a middle section and a tail section.

[0068] Still further, please refer to Figure 10 , Figure 10 The flow chart of the step S92 of the beautifying method of the ink screen stylus stroke provided by the present application.

[0069] Specifically, first, the latest stylus stroke report point data is divided into a head section, a middle section and a tail section according to preset proportions, and then the second beautifying width of the starting end of the head section and the second beautifying width of the ending end of the head section are obtained according to the report point number or the length of the head section, and the second beautifying width of the ending end of the tail section is obtained according to the report point number or the length of the tail section.
