Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and examples. It is to be understood that the specific embodiments described herein are for purposes of illustration and not limitation. It should be further noted that, for the convenience of description, only some of the structures related to the present invention are shown in the drawings, not all of the structures.
It should be noted that, for the sake of brevity, this description does not exhaust all alternative embodiments, and it should be understood by those skilled in the art after reading this description that any combination of features may constitute an alternative embodiment as long as the features are not mutually inconsistent.
The following provides a detailed description of various embodiments of the present invention.
Fig. 1 is a flowchart of a jitter optimization display method according to an embodiment of the present invention. The jitter optimization display method is used for terminal equipment, in particular for terminal equipment using an ink screen for display, and as shown in the figure, the jitter optimization display method comprises the following steps:
step S110: and acquiring frame picture data to be displayed.
In the display process of the electronic equipment, a processor of the electronic equipment generates a display picture according to an interface component of a currently running program, and the running program or an interface in the running program changes according to the operation of a user so as to regenerate the display picture correspondingly. Each display frame corresponds to one frame picture data. For the electronic device, the content to be displayed after the currently displayed frame image data corresponds to the frame image data to be displayed. For different programs, there are different combinations of components and colors, and the display images formed by the combination are generally images with rich colors, that is, the frame image data correspondingly carries rich color contents.
In the electronic equipment based on optical display module realization such as liquid crystal display, OLED display screen, the media of control formation of image need maintain drive signal in real time and can guarantee the existence of formation of image, for example liquid crystal display needs electric field control deflection angle, otherwise the liquid crystal resumes unordered distribution, shelters from all light-emitting and can not maintain the formation of image effect. Therefore, in the optical display module, even if the current display content is not changed, the frame picture data to be displayed needs to be acquired correspondingly, and only the frame picture data to be displayed is the same as the frame picture data of the previous frame. Compared with the electronic equipment based on the optical display module, the electronic equipment based on the ink screen can confirm to acquire frame picture data to be displayed when the display content changes.
Step S120: and generating gray scale image data according to the frame image data.
When the black-white ink screen is displayed, because the position of the pigment particles is adjusted through the driving of the electric field, imaging is realized, the colors of the configurable pigment particles are limited, and the imaging effect with rich colors cannot be realized. Therefore, to realize normal display of the ink screen, it is necessary to generate gradation picture data from the color frame picture data. The specific generation process is only to perform gray scale conversion according to the color data corresponding to each pixel, which is a general implementation manner of color processing and will not be described herein.
Step S130: and generating jittering picture data corresponding to the frame picture data according to the historical gray scale data and the historical jittering data cached in the image cache region.
The historical gray scale data refers to gray scale image data correspondingly generated in the display process of the current frame image data, the historical jitter data refers to jitter data corresponding to a final presented image when the ink screen is controlled to display in the display process of the current frame image data, and the data is not necessarily completely consistent with the jitter image data obtained by directly performing jitter processing on the current frame image. And the historical gray data and historical jitter data buffer and image buffer area is used for generating jitter image data which is actually given to the ink screen when the frame image data to be displayed is displayed.
In the actual display process, the frame image data to be displayed may correspond to an independently displayed image, at this time, no historical gray scale data and historical jitter data are used as the display reference in the image buffer area, the frame image data normally generates gray scale image data and jitter image data in sequence, and then the gray scale image data and the jitter image data are displayed according to the jitter image data, and the gray scale image data and the jitter image data are directly stored in the image buffer area.
If the frame image data to be displayed has pre-frame image data, namely historical gray data and historical jitter data are correspondingly existed, the gray image data and the historical gray data need to be compared, the change area of the gray image data relative to the historical gray data is confirmed, after the initial jitter data is generated according to the gray image data, the data corresponding to the change area in the initial jitter data is replaced to the historical jitter data, and the jitter image data corresponding to the frame image to be displayed is generated.
If the frame image data is only the color change with little local difference, and the comparison result of the corresponding gray scale image data is not changed, the subsequent processing process can be directly stopped at this time, the original display state can be maintained, for example, the color of a certain part of characters is automatically adjusted from (255 ) to (255, 254), and at this time, white is actually displayed.
The dither picture data is used to control the actual display effect of the ink screen, and the specific display control process is already implemented in the ink screen, which is not described herein again.
Step S140: and updating the gray scale picture data and the jitter picture data corresponding to the frame picture data to the image buffer area.
The gray scale data generated in step S120 and the dither data generated in step S130 are updated to the image buffer area to replace the original historical gray scale data and historical dither data, so as to implement the display process for the next frame.
In the jitter optimization display method, frame picture data to be displayed are acquired; generating gray scale picture data according to the frame picture data; generating shaking picture data corresponding to the frame picture data according to the historical gray scale data and the historical shaking data cached in the image cache region; and updating the gray scale picture data and the jitter picture data corresponding to the frame picture data to the image buffer area. By comparing the gray scale image data of two adjacent frames, the dithering image data of the frame to be displayed is generated on the basis of the dithering image data corresponding to the image data of the previous frame, thereby improving the smoothness of the display content of the changed area and avoiding the whole image from being updated.
In a specific implementation manner, the image buffer area comprises a first buffer area and a second buffer area;
correspondingly, the process of updating the jittered picture data and the related data in step S130 and step S140 may specifically include:
step S131: and if the historical gray scale data are not cached in the first cache region, caching the gray scale image data into the first cache region as the historical gray scale data.
Step S132: and generating shaking picture data according to the gray picture data, and caching the shaking picture data into a preset second cache region as historical shaking data.
Step S133: if historical gray scale data is cached in the first cache region, comparing the gray scale image data with the historical gray scale data to obtain a change region in the gray scale image data.
Step S134: and updating the gray picture data to the first cache region as historical gray data.
Step S135: and generating initial jitter data according to the gray scale image data, and replacing the data of the change area in the initial jitter data to the corresponding position of the historical jitter data to obtain jitter image data.
Step S136: and updating the jittered picture data to the second buffer area as historical jittering data.
The specific processing procedure in steps S131 to S136 is further described with reference to fig. 2 in conjunction with steps S110 and S120. As shown in fig. 2, assuming that the electronic device based on the ink screen is powered on again after being powered off, the processor may obtain first frame picture data 11a for displaying when the electronic device is powered on, at this time, two sub-partitions (i.e., the first buffer area and the second buffer area) in the image buffer area 20 do not buffer the historical grayscale data and the historical shaking data, the first frame picture data 11a correspondingly generates first grayscale picture data 11b, and performs shaking processing on the first grayscale picture data 11b to obtain first shaking picture data 11d, where the first grayscale picture data 11b and the first shaking picture data 11d are respectively stored in the first buffer area and the second buffer area as the historical grayscale data and the historical shaking data.
After the power-on operation is detected, the power-on display image needs to respond correspondingly, the display content (actually determined by the first jittering image data 11 d) corresponding to the currently displayed first frame image data 11a needs to change, and the frame image data corresponding to the first user operation is responded as the second frame image data 12a, namely the frame image data to be displayed after the first frame image data 11a is displayed is the second frame image data 12a. Accordingly, when the display process of the second frame picture data 12a is processed, the history gradation data and the history dither data buffered in the image buffer area 20 are the first gradation picture data 11b and the first dither picture data 11d, respectively. The second frame image data 12a correspondingly generates second gray scale image data 12b, the second gray scale image data 12b is compared with the first gray scale image data 11b cached in the image cache area 20, a second change area 12c relative to the first gray scale image data 11b in the second gray scale image data 12b is obtained, and the second gray scale image data 12b is subjected to dithering processing to obtain second initial dithering data. The data corresponding to the second change area 12c in the second initial shaking data is replaced with the first shaking picture data 11d buffered in the image buffer 20 to obtain the second shaking picture data 12d corresponding to the second frame picture data 12a, that is, the second shaking picture data 12d is not the shaking result directly corresponding to the second frame picture data 12a, but the data corresponding to the second change area 12c in the direct shaking result is extracted and replaced with the mixed result of the first shaking picture data 11d. In the specific display process corresponding to the second frame picture data 12a, the second gray scale picture data 12b and the second shaking picture data 12d are also stored in the first buffer area and the second buffer area, respectively, as new historical gray scale data and historical shaking data.
After the first user operation, a second user operation is detected, and the display content (actually determined by the second jittered picture data 12 d) corresponding to the currently displayed second frame picture data 12a needs to be changed corresponding to the second user operation, and the frame picture data corresponding to the second user operation is responded as the third frame picture data 13a, that is, the frame picture data to be displayed after the second frame picture data 12a is completely displayed is the third frame picture data 13a. Accordingly, when the display process of the third frame picture data 13a is processed, the history gradation data and the history dither data buffered in the image buffer area 20 are the second gradation picture data 12b and the second dither picture data 12d, respectively. The third frame image data 13a generates third gray scale image data 13b correspondingly, the third gray scale image data 13b is compared with the second gray scale image data 12b cached in the image cache area 20 to obtain a third change area 13c relative to the second gray scale image data 12b in the third gray scale image data 13b, the third gray scale image data 13b is subjected to dithering to obtain third initial dithering data, data corresponding to the third change area 13c in the third initial dithering data is replaced with the second dithering image data 12d cached in the image cache area 20, and third dithering image data 13d corresponding to the third frame image data 13a is obtained. That is, the third shaken image data 13d is not a shake result directly corresponding to the third frame image data 13a, but a mixed result obtained by extracting data corresponding to the third change area 13c in the direct shake result and replacing the extracted data with the second shaken image data 12d, and the third shaken image data 13d is actually a combination of shake results directly corresponding to the first frame image data 11a, the second frame image data 12a, and the third frame image data 13a. In the specific display process corresponding to the third frame picture data 13a, the third grayscale picture data 13b and the third dithering picture data 13d are also stored in the first buffer area and the second buffer area respectively as new historical grayscale data and new historical dithering data.
It can be found that, based on the above processing procedure, each frame of picture data is entirely dithered, the dithering result of each pixel is comprehensively affected by all other pixels, especially the dithering process of the change area can be affected by data outside the change area, based on this, the change area and the area outside the change area can naturally transit, and initial dithering data with good smoothness is obtained, the display picture corresponding to the initial dithering data has good integrity, and the data outside the change area is the same as the data of the corresponding area in the historical gray scale data.
In another optional implementation manner, in an actual processing process, the gray scale image data is updated to the first buffer area to serve as historical gray scale data, and it may also be determined that a ratio of an area of the change region to the gray scale image data is smaller than a preset first threshold value, that is, in the actual processing process, it is determined that the change region is smaller first, so that it is ensured that the change region has less influence on the overall shaking processing, and can be smoothly superimposed on the historical shaking data.
On the basis of the area ratio judgment, another optional implementation manner is that if the ratio of the area of the change region to the area of the gray scale image data is above the first threshold value, the gray scale image data is cached in the first cache region to serve as historical gray scale data; and generating shaking picture data according to the gray scale picture data, and caching the shaking picture data in a preset second cache region as historical shaking data. That is, in the actual processing, if it is confirmed that the change area is large, the influence on the entire dithering process is correspondingly large, and when the dithering process is completed, the data difference between the area outside the change area and the corresponding area in the history dithering data may be obvious, and the display of the change area and the other areas in the history dithering data may be large and poor in smoothness due to continuous superposition, at this time, the data in the image buffer area may be updated from zero directly from the frame of picture data.
In the specific implementation process, the first threshold in one specific display process may be a default preset threshold, a preset threshold automatically adjusted, or a preset threshold according to a user operation. The default preset threshold is a system default first threshold, and may be kept unchanged in the whole screen display process, or may be restored to the default first threshold after being changed, and a specific default first threshold is determined according to the device type and the application scenario, for example, 10%, 15%, and the like, and the specific numerical value is not an exclusive limitation of the present scheme. The preset threshold value can be automatically adjusted according to the change speed of the historical picture, for example, the faster the change speed is, the higher the first threshold value can be, thereby ensuring that the display process is completed as soon as possible when the picture is changed rapidly; the slower the change speed, the lower the first threshold value may be, and each change may have enough time to perform a global update, providing a smooth display. Of course, the automatic adjustment of the preset threshold value may be reconfirmation according to the operation type. The threshold value preset by the user operation is mainly preset by the operation based on the display mode, for example, if the user operation confirms the speed priority mode, the first threshold value is relatively large; the user operates the confirmation quality priority mode, and the first threshold value is relatively small. It should be noted that, in the process of displaying a screen once, the first threshold value can only be determined in one of the manners, but for the entire scheme, various preset manners may be supported, and the first threshold value is determined according to the current preset manner when displaying specifically. In addition, statistics can be carried out on the updating times of the historical gray data, and when the updating times of the historical gray data reach a preset second threshold value, the image cache region is emptied. According to the scheme, the jittering picture data is generated in a mode of integral jittering and partial replacement, but the difference of data cannot be eliminated, after a certain number of times of replacement, the frame picture data to be displayed and the frame picture data which is a few frames away from the frame picture data are possibly greatly distinguished, the earlier frame picture data are still displayed correspondingly, and the difference between the display of a change area and the initial jittering picture of the change area is obvious due to continuous superposition display.
