20250095236
The present application relates to the technical field of electronic devices, and in particular to an accelerated writing method, apparatus, electronic device and computer-readable storage medium.
Existing electronic devices, such as interactive large screens, normally have two operating systems, which are Windows and Android. Users use the Windows system, a picture of the Windows system is displayed by the Android system, but an interactive large screen is interacted with outside through the Android system, and is displayed by the Android system. When users input on the interactive large screen by writing, first the Android system sends interactive information to the Windows system, which processes the interactive information, and then the Windows system sends the display information to the Android system so as to display it on the large screen. Because the whole process is relatively complex, delay may occur especially when a trajectory is drawn on the interactive large screen.
To solve the technical problem of delay, an accelerated layer is disposed, i.e., a display cache area of the same writing trajectory directly drawn by the Android system is disposed on the interactive large screen. Because the trajectory drawn by the Android system is overlapped with the trajectory drawn by the Android system, and the speed of drawing the trajectory by the Android system is faster than the Windows system, Users may feel that the while trajectory is a trajectory in the Windows system, so that the problem of the delayed display is solved.

Referring to
For the ease of understanding, the final displays of the first writing trajectory, the second writing trajectory, the first preset trajectory and the second preset trajectory in the present application all are displayed by the display screen of the electronic screen, but displaying the first writing trajectory, the first preset trajectory and the second preset trajectory is implemented on the display screen by the first system through the second system (for the convenience of description, hereafter referred to as “displayed by the first system”), and the second writing trajectory is directly displayed on the display screen by the second system (for the convenience of description, hereafter referred to as “displayed by the second system”).
The accelerated writing method of the present application comprises the following steps S100-S500:
In step S100, the writing input information comprises a writing trajectory and a writing color (a first color). Therefore, the first system can start the first writing operation according to the writing input information, so that the first writing trajectory is displayed with the first color. Here, the writing input information may specifically be a touch information.
The first system may have multiple display modes, for example, a standard mode, a bright mode, a vivid mode, an eye-protecting mode and so on, and a same color has different RGB values of the color in different display modes. For example, the RGB value of red is (255, 1, 0) in the standard mode, (255, 0, 0) in the vivid mode, and (252, 1, 0) in the eye-protecting mode.
In step S100, the first system performs the writing operation (i.e., displaying the first writing trajectory) following the writing input information, and simultaneously the first system sends the first color to the second system.
In step S200, after the second system receives the first color, to obtain the actual color (i.e., the following rendering color) displayed on the display screen by the first color, the second system may send the display request comprising the first preset position of the display screen, so that the proceeding first system may display the first preset trajectory with the first color at a specified position (the first preset position) of the second system to facilitate that the second system obtains the rendering color from the position.
The first preset position is a position specified by the second system. That is to say, the first preset position is not constant, but the first preset position is determined by the second system according to the actual display situation of the display screen.
In some situations, the first system is not displayed in full screen, and the position of the first system may adjusted as needed. Meanwhile, the second system determines the first preset position within a display range of the first system according to the actual display situation of the first system.
The second system in the present application determines the first preset position according to the display of the first system, and the position is sent to the first system to ensure that the position that the second system obtains the rendering color is consistent with the position that the first system display the first preset trajectory.
In step S300, the first system may display the first preset trajectory with the first color at the first preset position of the display screen, so that the display screen may display the first color in the current display mode of the first system. Specifically, the first preset trajectory may be displayed by the second system on the display screen after the first system writes the first preset trajectory with the first color. Therefore, the color displayed on the display screen for the first preset trajectory is completely consistent with the color displayed on the display screen for the first writing trajectory to facilitate subsequently obtaining the actual first color (i.e., the color displayed on the display screen for the first color) by the second system from the first preset trajectory, so that the color of the second writing trajectory subsequently displayed by the second system is completely consistent with the color displayed on the display screen for the first writing trajectory.
Furthermore, the position displayed on the display screen for the first preset trajectory is the first preset position determined by the second system to facilitate that the second system obtains the rendering color from the specific position.
A size of the first preset trajectory may be selected to be relatively small, so that users basically does not perceive the existence of the first preset trajectory, thereby avoiding the influence of the first preset trajectory on users and ensuring the user experience. The shape of the first preset trajectory may be a square block, a circular block, a triangular block, or any other shape, as long as it is ensured that the second system may obtain the corresponding rendering color from the first preset trajectory in the subsequent step S400.
The time for displaying the first preset trajectory is the first preset time. After the first preset time elapses, the first preset trajectory should be cleared to avoid that the first preset trajectory is displayed on the display screen for too long time, and also to avoid that the first preset trajectory exists for a long time to possibly affect the user operation, so that the user experience is better improved.
The first preset time may set as need, and for example, the first preset time is 500-1500 ms, such as 500 ms, 600 ms, 800 ms, 1000 ms, 1200 ms or 1500 ms and so on.
In step S300, the second system may send the completing command, as long as the display screen displays the first preset trajectory.
In step S400, after the second system receives the completing command, the rendering color of the first preset trajectory may be obtained at the first preset position of the display screen, and the obtained rendering color may be referred to as the second color.
After the second system receives the completing command, rather than the rendering color being obtained at the first preset position immediately, the rendering color should be obtained after waiting the second preset time. Although the first system displays the first preset trajectory by the display screen, the display screen may have certain delay because the same reason in the background, rather than the first preset trajectory being displayed at the first time. The second preset time may cover the delay, so that the first preset position may actually display the first preset trajectory after the second preset time, thereby ensuring that the second system may accurately obtain the rendering color, and avoiding that the second system obtains a wrong color because the delay display.
The foregoing delay time of displaying the first preset trajectory normally is 0-100 ms, for example, Oms, 20 ms, 40 ms, 60 ms, 80 ms or 100 ms, which depend on the actual situation and here are given just for example. The second preset time is longer than the delay time, and shorter than the first preset time. The second preset time is set as specifically needed, and may be 100-300 ms, for example, 100 ms, 150 ms, 200 ms, 250 ms or 300 ms.
In step S500, the second system starts the second writing operation according to the writing input information, so that the second writing trajectory is displayed on the display screen, and the second color is taken as the color of the second writing trajectory. The colors eventually displayed on the display screen for the first writing trajectory and the second writing trajectory are exactly the same, because the second color is identical to the rendering color of the first preset trajectory which color is identical to the color displayed on the display screen for the first writing trajectory.
The first writing trajectory and the second writing trajectory are formed according to the same writing input information, i.e., the shape of the first writing trajectory is exactly consistent with the shape of the second writing trajectory, and the first writing trajectory overlaps the second writing trajectory on the display screen. The second writing trajectory is displayed by the second system, and may be displayed faster on the display screen than the first writing trajectory, so that the second writing trajectory may implement the acceleration of the first writing trajectory. After completing the first writing trajectory (when the current writing input information ends; specifically, when the writing termination command may be detected), the second writing trajectory may be cleared. Then, only the first writing trajectory is displayed on the display screen. Because the second writing trajectory is completely identical to the first writing trajectory, users may not perceive that the second writing trajectory is eliminated, so that the user experience is ensured.
In some embodiments, the electronic device pre-stores the corresponding relationship among the first color, the display mode and the second color, and the second system may directly obtain the second color according to the corresponding relationship, so that no further foregoing step S300 and step S400 need to be performed.
In the embodiment, step S200 comprises the following steps S210-S230:
In step S200, it is determined first whether the first color and the second color corresponding to the current display mode of the first system exist in the corresponding relationship, and if the corresponding relationship exists, the second color may be directly obtained according to the corresponding relationship, so that step S500 may be directly performed subsequently.
If the corresponding relationship does not exist, step S300 and step S400 should be performed, so that the corresponding relationship obtains the second color. In step S200, if the determination result is no, the command (the display request) should be sent to the first system, so that step S300 is performed by the first system.
After completing step S400, the corresponding relationship among the first color, the current display mode and the second color is obtained. Then, the corresponding relationship may be stored in the electronic device, so that the whole range of corresponding relationships is extended to facilitate the subsequent writing, and the second color is directly obtained in the case of the same first color and display mode without performing steps S300 and S400 any more. Therefore, the time for obtaining the second color is shortened, the formation of the second writing trajectory is further accelerated, and the accelerated writing efficiency of the second system is improved.
There are some differences among the display screens of different electronic devices, so that different electronic devices have the problem of color deviation when displaying the same color. Additionally, given that the electronic device may age after longtime use, the foregoing corresponding relationship need to be adaptively adjusted according to different electronic devices and durations of use.
As a result, in a preferred embodiment of the present application, the second system does not pre-store the corresponding relationship among the first color, the current display mode and the second color, but a corresponding relationship table may be temporarily stored each time the writing software is started. The corresponding relationship table is cleared when the current writing software is shut down. Specifically, after each time the writing software is started, the corresponding relationship among the first color, the current display mode and the second color is obtained after step S400 is performed, so that it is ensured that the corresponding relationship as obtained may be completely matched with the electronic device, and then if the first color and the current display mode existing in the corresponding relationship occur subsequently, and the second color matched with the first color may be directly obtained according to the corresponding relationship in step S200. Therefore, the time of obtaining the second color is shortened, the formation of the second writing trajectory is further accelerated, and the accelerated writing efficiency of the second system is improved. Furthermore, the accelerated writing method further comprises step S600, which clears the corresponding relationship among the first color, the current display mode and the second color in a system when the writing termination command is ended.
The corresponding relationship among the first color, the current display mode and the second color in the present application works only when the accelerated writing method is performed. When the writing termination command is detected, it is indicated that no writing input information is further performed, so that the foregoing corresponding relationship may be deleted so as to reduce the system burden. Specifically, the writing termination command may be a command of shutting down the writing software. That is to say, the corresponding relationship among the first color, the current display mode and the second color is restored each time the writing software is reloaded.
Undoubtedly, step S600 can be not performed. That is to say, after the writing ends, the foregoing corresponding relationship may still be stored in the system to facilitate invoking the writing input information at the next time.
In an embodiment in which the corresponding relationship is still stored in the system, the corresponding relationship should be cleared after ending a writing. For example, it is cleared once for 3 months (it may also be other time, for example, 6 months or 1 years, etc., and the time of periodic clearing is manually set), so as to prevent the electronic device from aging causing deviation of the corresponding relationship.
To the first preset position, the first preset position is preferably located in the non-user operation area of the display screen.
An image displayed by the first system through the display screen comprises the user operation area and non-user operation area. Users perform a writing input in the user operation area, so that the first preset position is disposed in the non-user operation area by the second system. Therefore, in step S300, it may be avoided that the first preset trajectory displayed by the first system disturbs the user operation area and also that the displayed first preset trajectory is disturbed by other information inputted by users or even erased by users before the displayed first preset trajectory is obtained by the second system so as to render the obtained second color inaccurate.
Taking a drawing as an example, the first system displays a whiteboard for drawing and an external frame outside the whiteboard. The whiteboard is the user operation area, and the external frame is the non-user operation area. During drawing, the user performs a writing operation in the area of the whiteboard, so that the first preset position is located on the external frame to avoid disturbing the writing input information.
Undoubtedly, in another embodiment, the first preset position may be located in the user operation area of the display screen, or in the marginal position of the user operation area, so that the disturbing of the writing operation is reduced; the position where the beginning end of the first writing trajectory is located is taken as the first preset position, and a trajectory of the beginning end is taken as the first preset trajectory.
In an embodiment in which the first preset position is in the non-user operation area, non-user operation area have four corner positions. In an embodiment, one first preset position is disposed and specifically may be one of corner positions. In another embodiment, two first preset positions are disposed and are two corner positions of a diagonal of the non-user operation area respectively, and in this embodiment, step S400 comprises:
obtaining, by the second system, the rendering color of the first preset trajectory at each of the first preset positions after waiting the second preset time; comparing the two rendering colors to determine whether they are consistent with each other; and under the condition that the two rendering colors are consistent with each other, taking the rendering colors as the second color.
In some situations, because some known or unknown reasons, the first preset trajectory is not displayed at the first preset position when the first system attempts to display the first preset trajectory at the first preset position, so that there is some difference between the position of the first preset trajectory and the first preset position. In step S400, the second system still obtains the rendering color at the first preset position, which results in the rendering color obtained by the second system being different from the color of the first preset trajectory.
To solve the problem, in an embodiment of the present application, two first preset positions are disposed, and these two preset positions are located at two corner positions of a diagonal of the non-user operation area respectively. In step S300, the first system displays the first preset trajectory at the two first preset positions. In actual applications, a side of the display screen of the electronic device has a lower probability of being shifted, for example, an upper side is shifted by certain size downwards, so that one of the first preset positions may not display the first preset trajectory, and the situation in which the wrong rendering color is obtained may occur. Additionally, the two first preset positions are disposed at the two corner positions of a diagonal. Normally, only the situation in which the display panel have one shifted side may occur. Therefore, only the situation of one wrong rendering color may occur when one side is shifted. It may be determined whether the rendering colors respectively obtained by the two first preset positions are consistent with each other; if yes, the rendering color may be the second color; otherwise, it may mean that at least one of the first preset positions may not display the first preset trajectory, so that the second color cannot be determined.
Furthermore, whether the two rendering colors are consistent with each other means that the RGB values of the two rendering colors are close to each other. Specifically, each difference value of R, G and B between the two rendering colors is calculated separately; if the three difference values all are less than a set value, which normally may be 3-5, for example, 3, 4 and 5, then the two rendering colors may be considered close; otherwise, the two rendering colors may be considered inconsistent with each other.
Furthermore, in another embodiment of the present application, if the two rendering colors are inconsistent with each other, the second color may not be obtained, and therefore step S500 need not to be performed, i.e., the second system does not accelerate the second writing trajectory.
Undoubtedly, in some situations, a situation that two opposite sides of the display screen shift may occur, for example, an upper side shifts downwards, and an lower side shifts upwards, so that the upper and lower sides have a black edge simultaneously, and both the two first preset trajectories have color deviation. Then, both the two rendering colors as obtained are black (the color of the black edge), leading to the situation in which the wrong second color is obtained.
To avoid occurring the situation of obtaining a wrong color, in an embodiment of the present application, in step S200, the display request further comprises: displaying the third color at the second preset position of the display screen, wherein there are two second preset positions, which are two corner positions of another diagonal in the non-user operation area, respectively, and the third color is the color that is different from the first color.
In step S300, before the sending of the completing command, step S300 further comprises: rendering the second preset trajectory with the third color in the first preset time at each of the second preset positions. That is to say, the first system displays the first preset trajectory with the first color at the first preset position, and the second preset trajectory with the third color at the second preset position; and the first preset trajectory and the second preset trajectory are displayed and disappeared simultaneously.
In step S400, when receiving the completing command and after waiting for the second preset time, the second system obtains the rendering color of the first preset trajectory at each of the first preset positions and colors of the second preset trajectories at the second preset positions, and taking colors of the second preset trajectories at the second preset positions as a first check color and a second check color, respectively;
the second system compares the rendering color of the first preset trajectory at each of the first preset positions, the first check color and the second check color, and if the following conditions are satisfied, takes the rendering color as the second color:
condition 1: the two rendering colors are consistent with each other;
condition 2: the first check color is consistent with the second check color; and
condition 3: the first check color and the second check color are inconsistent with the respective adjacent rendering colors.
As an example, the two first preset positions are located at the upper left corner and the lower right corner of the non-user operation area respectively, and the two second preset positions are located at the lower left corner and the upper right corner of the non-user operation area.
In step S400, the second system obtains the colors at four preset positions. The colors obtained at two first preset positions are the rendering colors, which are the actual color of the first color theoretically. Two check colors are obtained at two second preset positions obtain. For example, the first check color is obtained at the second preset position of the lower left corners, and the second check color is obtained at the second preset position of the upper right corner. Theoretically the first check color should be identical to the second check color, and the first check color and the second check color are the color in which the third color actually displayed through the display screen.
In the situation in which both the upper side and the lower side are black edges, the two check colors as obtained are black. Then, the obtained rendering colors are consistent with the two check colors, resulting in failure to satisfy the condition 3, so that it can be determined that a wrong rendering color is obtained, and the rendering color shall not be taken as the second color.
Furthermore, if the first color is a bright color, the third color may be dark gray; if the first color is a dark color, the third color may be bright; wherein the bright color is the color whose RGB value is larger than a preset value.
If the first color is a bright color, the rendering color should also be bright; if the third color is dark gray, the first check color and the second check color should also be dark gray; therefore, it is easy for the second system to determine whether the foregoing condition 3 is satisfied. Likewise, if the first color is dark, the rendering color should also be dark; if the third color is bright gray, the first check color and the second check color are also bright gray, so that no matter the first color is bright or dark, it is easy for the second system to determine whether the condition 3 is satisfied through the third color corresponding to the first color.
In the embodiment, a bright or dark color of gray is selected as the third color, or a bright or dark color of other colors is selected as the third color.
The R value of the RGB value of the foregoing bright color is larger than 180, the G value thereof is larger than 180, and the B value thereof is larger than 180.
At least one value of the R value, G value and B value in the RGB value of the dark color is less than or equal to 180.
As previously mentioned, the second preset trajectories are located at two corner positions of the other diagonal of the non-user operation area. Generally the positions of the second preset trajectories may overlap a title bar and a task bar, and the selection of gray may result in the color of the second preset trajectory is close to the color of the title bar and the task bar, thereby avoiding disturbing users. Furthermore, the R value, G value and B value of gray are equal, so that only one value need to be obtained so as to perform the comparisons required by the condition 2 and the condition 3, thereby making the processing convenient. The third color may adopt a bright color or a dark color of other colors, for example, a bright red color, a dark red color, a bright yellow color or a dark yellow color.
In other embodiments, the third color may be an invert color of the first color, but in some situations, the invert color of some color is close to the first color, so that the determination of the condition 3 by the second system may be affected.
For example, the RGB value of gray is (127, 127, 127), its invert color is gray (128, 128, 128), and therefore the first color is relatively close to the third color at this time, so that the determination of the condition 3 is not facilitated.
Therefore, in the embodiment in which the third color is the invert color of the first color, the invert color of the first color is obtained first according to the first color, and then a similarity of the first color with the invert color thereof is determined. If the similarity of the first color with the invert color thereof is beyond the similarity range, i.e., the first color is quite different from the invert thereof, then the invert of the first color may be taken as the third color; otherwise (within the similarity range), the invert color of the first color may not be taken as the third color.
To determine whether the similarity of the first color with the inverse color of the first color is beyond the similarity range or not, the R value, G value and B value of the first color are compared with the R value, G value and B value of the invert color of the first color, respectively; if the differences of the R value, G value and B value between the two colors are within the preset range, then the two colors are not beyond the similarity range. For example, the preset range is from 1 to 50, and may be adjusted as needed.
If it is determined that the invert color of the first color cannot be taken as the third color, the third color may be determined as dark gray or bright gray according to the bright color or dark color of the foregoing first color, and details are not described herein again.
When receiving the termination command of the current writing input information, the second system erases the second writing trajectory.
Taking a drawing as an example, the user performs the writing input information on the display screen of the electronic device through a finger or a stylus, and when the writing input information ends (the stylus is lifted), the second system displays the second writing trajectory, and should erase the second writing trajectory after the first system completes the first writing trajectory.

Under a condition that the first system of the present application displays the first writing trajectory with the first color according to the writing input information, the first system further displays the first preset trajectory with the first color, the second system obtains a color of the first preset trajectory, and the second writing trajectory is started in the color of the first preset trajectory, so that the color of the first writing trajectory is consistent with the color of the second writing trajectory, and the user experience is ensured.
