Based on the hardware structure of the equipment, the embodiment of the quick refreshing method for the ink screen is provided.
Referring to fig. 2, in a first embodiment of the ink-water screen fast refreshing method of the present invention, the ink-water screen fast refreshing method includes:
step S10, when a screen refresh command is received, acquiring a current frame corresponding to the screen refresh command, and a previous frame and a next frame corresponding to the current frame.
The quick ink screen refreshing method in the present embodiment is applied to a device with an ink screen, for example, an electronic book, and an optimal device with an ink screen (hereinafter, collectively referred to as an ink screen device) in the present embodiment is an electronic ink screen supporting handwriting.
When the quick ink and water screen refreshing program receives a screen refreshing instruction, acquiring a current frame picture corresponding to the screen refreshing instruction, wherein the screen refreshing instruction can be sent by an application (or a system) in equipment with an ink and water screen, the current frame picture corresponding to the screen refreshing instruction refers to a picture which needs to be displayed by the electronic ink and water screen after the screen refreshing instruction is received, for example, when a clock program of the ink and water screen equipment needs to refresh a clock for display, a screen refreshing instruction is generated, and the screen refreshing instruction is sent to the quick ink and water screen refreshing program, for example, a picture which is refreshed from 12:26:50 to 12:26:51, 12:26:51 is the current frame picture in the embodiment, and the picture does not consider picture changes at other positions of the ink and the last frame picture in the embodiment refers to a picture displayed on the ink and water screen when the screen refreshing instruction is received, if the screen refresh command is received at the instant after the ink and wash screen device is started, the previous frame of picture is the start-up display picture of the ink and wash screen device, and the next frame of picture in this embodiment means that the application generally sends a plurality of frames of pictures to be displayed to the ink and wash screen fast refresh program in advance, and the picture next to and after the current frame of picture is the next frame of picture in this embodiment.
Step S20, performing absolute difference calculation on the current frame, the previous frame, and the next frame to obtain a first difference frame and a second difference frame, and determining a first pixel point in the first difference frame and a second pixel point in the second difference frame.
After a previous frame picture, a previous frame picture and a next frame picture are obtained, an ink-wash screen quick refreshing program can carry out absolute difference calculation on the previous frame picture, the previous frame picture and the next frame picture, specifically, the absolute difference calculation means that all pixel points forming the pictures of two adjacent frames are correspondingly compared, if the comparison results of the corresponding pixel points in the two adjacent frames are equal, the pixel point cannot exist in the difference picture obtained after the two adjacent frames are compared, particularly, if the two adjacent frames are completely same, no difference picture exists or the difference picture is empty, specifically, the absolute difference calculation is carried out on the current frame picture and the previous frame picture to obtain a first difference picture, the absolute difference calculation is carried out on the next frame picture and the current frame picture to obtain a second difference picture, and after the difference between the first difference picture and the second picture is obtained, the quick ink screen refreshing program can determine a first pixel point in the first difference picture and a second pixel point in the second difference picture.
Step S30, if the first pixel point and the second pixel point are not overlapped, performing a refresh operation on the second pixel point after the refresh of the first pixel point is completed.
In the electronic ink screen, the pixel points are actually electronic ink composed of tiny transparent particles, the time required for refreshing from one color to another color is very short, but the refreshing period of each piece of electronic ink is longer than the color refreshing time, that is, in one refreshing period, one pixel point can refresh the color only once, in this embodiment, the first pixel point and the second pixel point are not overlapped, that is, the position of the first pixel point and the position of the second pixel point are not intersected, and in this way, each pixel point in the ink screen has a fixed position, whether the first pixel point and the second pixel point are overlapped can be determined by determining the positions of the first pixel point and the second pixel point in the ink screen, if the first pixel point and the second pixel point are overlapped, the refreshing operation is performed on the second pixel point after the refreshing of the first pixel point is completed, the second pixel point is refreshed after the first pixel point finishes the whole refreshing period, the refreshing speed of the ink screen is visually improved, and therefore, if the first pixel point is overlapped with the second pixel point, one pixel point can refresh the color once in one refreshing period, and the second pixel point can only perform refreshing operation after the first pixel point finishes the whole refreshing period.
Specifically, the step of step S20 refinement includes:
step a1, if it is determined that the current frame is the same as the previous frame according to the calculation result of the absolute difference calculation, performing an ignoring operation on the screen refresh event corresponding to the current frame, and taking the next frame as the current frame after the ignoring operation.
Step a2, obtaining the next frame after the neglect operation, and returning to the step of calculating the absolute difference between the current frame, the previous frame and the next frame.
It can be known that, if it is determined that the current frame is the same as the previous frame according to the calculation result of the absolute difference calculation, that is, the first difference frame is empty, and there is no first pixel point, there is no judgment process for determining whether the first pixel point and the second pixel point coincide with each other, in this case, the rapid ink-wash screen refresh program ignores the screen refresh event corresponding to the current frame, specifically, the refresh of each frame corresponds to one screen refresh event, and the application or system refreshes the current frame by calling the screen refresh event, and after the screen refresh event is ignored, the rapid ink-wash screen refresh program ignores the refresh of the current frame corresponding to the screen refresh event, and then obtains the next frame of the next frame in the above-mentioned contents from the image storage area, that is, the next frame after the operation is ignored in this embodiment, then, the next frame of picture in the content is taken as the current frame of picture in the content, and it can be understood that the above operation is similar to queuing, when one frame of picture in the team is removed, the following pictures will be sequentially supplemented with the vacant positions, and the steps of performing the absolute difference calculation on the current frame of picture, the previous frame of picture and the next frame of picture are circularly performed on the respective positions until the first difference picture and the second difference picture which are not vacant are obtained.
In this embodiment, when the rapid ink-wash screen refresh program receives a screen refresh command, a current frame picture corresponding to the screen refresh command is obtained from a preset image storage area, that is, a picture to be displayed currently on the ink-wash screen, and a previous frame picture and a next frame picture corresponding to the current frame picture, and further, absolute difference calculation is performed on the current frame picture, the previous frame picture and the next frame picture to obtain a first difference picture and a second difference picture, then, a first pixel point in the first difference picture and a second pixel point in the second difference picture are determined, and finally, whether the first pixel point and the second pixel point are overlapped is determined, and if the first pixel point and the second pixel point are not overlapped, a refresh operation is performed on the second pixel point after the refresh of the first pixel point is completed. The second pixel points can execute the refreshing operation without waiting for the first pixel points to go through the whole refreshing period, the refreshing flow of the electronic ink screen is simplified, and the refreshing speed of the electronic ink screen is improved.
Further, referring to fig. 3, a second embodiment of the quick refresh method for the ink-jet screen according to the present invention is provided on the basis of the above-mentioned embodiment of the present invention.
This embodiment is a step before step S10 in the first embodiment, and the difference between this embodiment and the above-described embodiment of the present invention is:
step S40, when it is detected that the preset operating system is started, creating a system service, and switching a working mode corresponding to the system service to a peripheral mounting mode, so that the preset application generates an update screen.
Step S50, creating an image storage area in the system service, and saving the last displayed screen before the switching of the operation mode to the image storage area.
And step S60, when the updated picture is detected, saving the updated picture to the image storage area, and generating a screen refresh command through the preset application.
It should be noted that, the preset operating system in this embodiment refers to an operating system supported by the ink screen device, and is generally an android system, the system service in this embodiment refers to a program (application) that executes a specified system function, and the operating modes of the system service driver chip include a direct drive mode and a USB peripheral mounting mode, where the direct drive mode is not described in detail in this embodiment, the USB peripheral mounting mode is the peripheral mounting mode in the embodiment, when the ink screen device is powered on, the preset operating system is started and creates a system service, and then the operating mode of the system service driver chip is adjusted to the USB peripheral mounting mode, as can be appreciated, the operating modes of the two driver chips are mutually exclusive, and a delay of approximately 1.5 seconds is required to switch the two operating modes, therefore, when the preset operating system is started, the operating mode of the system service driver chip is immediately switched to the peripheral mounting mode, therefore, the updated picture in the embodiment includes a picture which is generated by the application autonomously to refresh the display picture of the ink-jet screen, and also includes a picture which is generated by the user using the external device to refresh the display picture of the ink-jet screen, for example, the user performs handwriting operation on the ink-jet screen by using electromagnetism, and a track handwritten by the user will cause the refresh of the display picture of the ink-jet screen. Therefore, after the system service is created, the ink and wash screen quick refresh program creates an image storage area in the system service for storing the picture to be updated, when the ink and wash screen quick refresh program detects the updated picture generated by the preset application, the updated picture generated by the preset application is stored in the image storage area, and then a screen refresh command is generated through the preset application.
Specifically, the step of step S10 refinement includes:
step b1, when receiving a screen refresh command sent by the preset application, acquiring the updated picture and the screen picture, and taking the screen picture as a previous frame picture, wherein the current frame picture and the next frame picture belong to the updated picture.
It should be noted that the updated frame in this embodiment is a frame to be displayed generated by a preset application, and it is understood that the updated frame includes more than one frame, and generally includes several frames of frames to be updated, and the frames of two adjacent frames in the updated frame do not necessarily change, the screen in this embodiment refers to a last frame displayed by the ink screen before the system service driver chip is switched to the peripheral mounting mode, if the operating mode of the system service driver chip is the peripheral mounting mode when the preset operating system is started, that is, there is no mode switching, the screen is a last frame displayed by the ink screen before the updated frame generated by the preset application after the preset operating system is started, and it is known that after the ink screen fast refresh program acquires the screen and the updated frame, the screen is taken as a previous frame in the above embodiment, and the current frame and the next frame belong to the updated frame, and the current frame picture is adjacent to the next frame picture and arranged at the front position in the updated picture.
Specifically, steps subsequent to step S50 include:
step c1, creating system interface service in the system service, wherein the system interface service comprises refresh mode switching service, peripheral detection service and manual image data transfer service.
Step c2, if the refresh mode is determined to be the manual refresh mode according to the detection result obtained by the peripheral detection service, obtaining manual image data corresponding to the manual image data transmission service, and using the manual image data as the update picture.
The system interface service in this embodiment is an interface definition language, and can implement services provided by free access between application programs, and the system interface service in this embodiment includes a refresh mode switching service, a peripheral detection service, and a manual image data transfer service, and specifically, the refresh mode switching service is a function of switching between an automatic refresh mode and a manual refresh mode, where the refresh mode switching service is a function of manually refreshing an ink screen by a user through a peripheral device, and the peripheral detection service is a function of detecting whether the ink screen device is connected to an external device, such as an electromagnetic pen, and the manual image data transfer service is a function of transferring a manually generated writing track screen. And if the refresh mode is determined to be the manual refresh mode according to the detection result obtained by the peripheral detection service, acquiring manual image data corresponding to the manual image data transmission service, and taking the manual image data as an update picture.
Specifically, the steps after step c2 include:
and d1, if the refresh mode is a manual refresh mode, determining a refresh area corresponding to the black-white pixel point in unit frame time when the black-white pixel point is detected, wherein the black-white pixel point is a pixel point which is changed in black and white.
Step d2, querying a target time point when the black-and-white pixel point in the refresh area is refreshed, obtaining a target picture generated by the preset application at the target time point, and overlapping the refreshed black-and-white pixel point with the target picture to obtain a picture as the updated picture.
It should be noted that the black and white pixel point in this embodiment is a pixel point that changes from black to white or from white to black, specifically, in this embodiment, the color change triggered by the electromagnetic pen is a black and white change, when the electromagnetic pen is used as a writing pen, the color change on the writing track is from white to black, when the electromagnetic pen is used as an eraser, the color change on the writing track is from black to white, if the refresh mode is a manual refresh mode, and a black and white pixel point with a black and white change is detected, a refresh area corresponding to the black and white pixel point within a unit frame time is determined, where the unit frame time is a time required for refreshing a frame of picture, for example, if the frame rate for refreshing the screen of the ink screen is 40, i.e., 40 times per second, the unit frame time is 25 milliseconds, a refresh area corresponding to the black and white stroke pixel point within the unit frame time is an electromagnetic track within 25 milliseconds, after a target time point when the refreshing of the black and white pixel points in the refreshing area is completed is inquired, the quick refreshing program of the ink-water screen acquires a target picture generated by the preset application at the target time point, and finally, a picture obtained by overlapping the refreshed black and white pixel points with the target picture is used as an updated picture, wherein the frequency of the updated picture generated by the preset application in the embodiment can be 40 per second, each updated picture is provided with a time label for determining the target picture generated by the preset application at the target time point, wherein the target picture belongs to the updated picture, and it can be understood that the overlapping of the refreshed black and white pixel points and the target picture is simple pixel coverage, namely the refreshed black and white pixel points cover pixel points at the same positions as the refreshed black and white pixel points in the target picture.
Specifically, the steps after step c1 include:
step e1, if the refresh mode is determined to be the auto-refresh mode according to the detection result obtained by the peripheral detection service, when it is detected that the screen refresh event is triggered, it is determined whether there is a target pixel point within a preset refresh period.
