Fig. 1 is a flow chart of a method for controlling a screen split refresh rate of an intelligent wearable watch according to an embodiment of the present invention;
fig. 2 is a schematic diagram of a smart wearable watch screen partition.
Detailed Description
The following description of the embodiments of the present invention will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present invention, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the invention without making any inventive effort, are intended to be within the scope of the invention.
Referring to fig. 1, a flowchart of a method for controlling a screen zone refresh rate of an intelligent wearable watch according to an embodiment of the invention is shown, and the method includes the following steps:
step S001, acquiring intelligent wearable watch screen operation parameters.
It should be noted that, in general, the image is characterized by static change, but due to the persistence effect, when the display screen is refreshed and played at a speed of 24 frames per second, the static image is characterized by dynamic continuity. Therefore, in order to ensure smooth display of the screen images of the intelligent wearable watch, the screen refresh rate needs to be adjusted in combination with the actual running state of the screen of the current intelligent wearable watch, and at this time, the state parameters of the screen of the intelligent wearable watch and the data of the buffer zone need to be acquired, including the size of the screen of the intelligent wearable watch and the data of the display buffer zone.
Step S002, obtaining short-time segments of the intelligent wearing watch screen operation parameters, calculating frequent interaction mark characteristics of each short-time segment according to the intelligent wearing watch screen operation parameters, dividing the intelligent wearing watch into frequent interaction states and inactive interaction states by using the frequent interaction characteristics, and setting the refresh frequency of the intelligent wearing watch screen in the inactive interaction states as a first refresh rate.
It should be noted that, in order to extend the actual endurance time of the smart wearable watch as far as possible, the refresh frequency of the screen of the smart wearable watch needs to be optimally controlled according to the running states of the smart wearable watch at different moments, so that the running states of the smart wearable watch at different moments need to be detected first.
Specifically, in time of dayThe touch point level data as the starting point is taken forward by length +.>Short-time segment of->Taking a preset experience value of->The frequent interaction state of the intelligent wearable watch can be calculated and characterized by short time segments at different time positions.
In the method, in the process of the invention,represents +.>Touch point level maximum value of intelligent wearable watch in short time segment, +.>Represents +.>Touch level minimum value of smart wearable watch in short time segment, < >>Represents +.>Total number of touch interactions in a short time segment, +.>Representing the magnitude of the frequent interaction preset threshold, < >>Represents +.>Frequent interaction at short time segments marks features.
When a user interacts with the intelligent wearable watch, the touch level in the touch area becomes higher relative to the touch levels in other non-touch areas, so that the larger the difference between the maximum value and the minimum value of the touch level of the intelligent wearable watch is in a short time segment, the interaction between the user and the intelligent wearable watch is indicated in the short time segment, and meanwhile, the higher the number of times of the touch level value of the intelligent wearable watch in the short time segment is when the interaction response between the user and the intelligent wearable watch is more frequent. In particular, in order to avoid frequent interaction sign feature changes caused by higher touch level values of the intelligent wearable watch due to false touches, the invention sets a frequent interaction preset threshold to be an experience value of 3, and in specific application, an implementer can set according to specific situations. The method comprises the steps that when the number of times that the intelligent wearable watch touches the high level is greater than 3 in a short time segment, the user is considered to interact with the intelligent wearable watch truly, the frequent interaction sign characteristic of the short time segment is 1, otherwise, the frequent interaction sign characteristic of the short time segment is 0, and the fact that the intelligent wearable watch is in an inactive interaction state at the current moment is indicated.
Step S003, calculating intelligent wearing watch screen association display coefficients at different moments according to intelligent wearing watch screen operation parameters, acquiring an intelligent wearing watch full-screen refreshing state according to the intelligent wearing watch screen association display coefficients at different moments, and setting screen refreshing frequency of the full-screen refreshing state as a second refreshing frequency.
It should be noted that, when the intelligent wearable watch is in the inactive interaction state, in order to achieve the purpose of energy-saving and power-saving of the intelligent wearable watch and prolonging the endurance time of the intelligent wearable watch, the normal clock display state is considered to be maintained, the screen refresh rate of the intelligent wearable watch needs to be maintained at a relatively low frequency, otherwise, if the intelligent wearable watch is in the active interaction operation state, the screen of the intelligent wearable watch needs to be maintained at a relatively high frequency in order to ensure the normal and smooth display of the screen of the intelligent wearable watch.
Specifically, the invention inquires the frequent interaction mark characteristic of the intelligent wearing watch once every a short time segment length, if the intelligent wearing watch is in an inactive running state at the current moment, the value of the frequent interaction mark characteristic corresponding to the intelligent wearing watch is 0, so that the screen refreshing frequency of the intelligent wearing watch in the inactive state is maintained to be the first refreshing frequency,i.e. refreshed once a second, consistent with the display change of the clock.
Particularly, when the frequent interaction characteristic value of the intelligent wearable watch is 1, the intelligent wearable watch is in an active running state in the current state, and the screen of the intelligent wearable watch is updated according to the row sequence from top to bottom in the refreshing processThe screen is refreshed at different locations. Because the round screen of the watch is worn intelligently, the number of the display array LEDs of each different row in the round screen is different, and the moment is assumedThe smart wearable watch screen display buffer length of (1) can support +.>LED display of a different smart wearable watch.
It should be noted that, in a normal display process of video animation display, a complete frame of picture needs to be sent each time, so as to achieve normal refresh display in the screen display process. However, most of the physical indexes of the intelligent wearable watch are monitored and displayed in real time in the instant messaging or the movement process in the actual application scene, the display picture of the intelligent wearable watch does not need to be refreshed completely, but only the local display area of the intelligent wearable watch is refreshed, so that the display picture refreshing area of the screen of the intelligent wearable watch needs to be adjusted.
Specifically, the screen refreshing state of the intelligent wearable watch needs to be calculated and characterized according to the data of the display refreshing area of the intelligent wearable watch and the current screen display data state of the intelligent wearable watch.
；
In the method, in the process of the invention,、/>representing maximum and minimum functions, respectively, < ->、/>Respectively show the width and height dimensions of the display screen of the smart wearable watch, < >>Represents +.>Intelligent wearable watch screen at moment +.>Line->The magnitude of the value of the display screen level of the intelligent wearable watch at the position of the column, < >>Represents +.>Intelligent wearable watch screen at moment +.>Line->Column display buffer level value size, < >>Representing the cosine similarity function between two different vectors,/>Time +.>Intelligent wearable watch display vector at department, +.>Time +.>Intelligent wearable watch display bufferVector (S)>Time +.>The smart wearable watch screen at the location correlates display coefficients.
It should be noted that, the row level data in the display screen of the intelligent wearing watch at different moments is used as the first dimension of the display vector of the intelligent wearing watch, the column level data in the display screen of the intelligent wearing watch at different moments is used as the second dimension of the display vector of the intelligent wearing watch, the row level data in the display buffer of the intelligent wearing watch at different moments is used as the first dimension of the display buffer vector of the intelligent wearing watch, and the column level data in the display buffer of the intelligent wearing watch at different moments is used as the second dimension of the display buffer vector of the intelligent wearing watch.
The related display coefficient of the display screen of the intelligent wearing watch can be calculated through the above formula, the display buffer zone data of the intelligent wearing watch represents the picture data of the next frame of display in the display screen of the intelligent wearing watch, if the similarity coincidence degree between the level data of the current picture of the intelligent wearing watch and the data of the next frame of display picture in the display buffer zone is higher, because the level value at the corresponding position of the intelligent wearing watch should be relatively higher when the picture is displayed in the display screen of the intelligent wearing watch, if the intelligent wearing watch is not in the video playing display state, the ratio of the display level of the screen of the intelligent wearing watch to the level value sum of the display buffer zone is relatively close, and meanwhile, the similarity of the display vectors of the intelligent wearing watch calculated at different positions is also higher, therefore, if the screen of the intelligent wearing watch is not in the full-screen video playing display state, the related display coefficient of the screen of the intelligent wearing watch calculated at the moment is not in the full-screen video playing display stateThe value of (2) will be relatively large.
It should be noted that, if the screen of the smart wearable watch does not need to be refreshed, the value of the screen association display coefficient of the smart wearable watch should be relatively large in a short time segment, that is, the screen data of the smart wearable watch should have a strong similar association change characteristic in the short time segment, so that the change condition of the screen display data of the smart wearable watch needs to be analyzed.
Specifically, first for a length ofThe screen associated display coefficient of the intelligent watch at the corresponding moment can be calculated at each position at different moments in the short time segment of (a), when the moment +.>When the associated display coefficient of the intelligent wearable watch screen is larger than or equal to the average value of the associated display coefficients at all different moments in the short-time segment, the similarity between different picture frame data in the intelligent wearable watch screen is smaller, so that the current moment->The intelligent wearing watch screen is in a full screen refreshing state, the refreshing rate of the intelligent wearing watch screen is set to be a second refreshing frequency,/the intelligent wearing watch screen is in a full screen refreshing state>。
Step S004, dividing the screen of the intelligent wearing watch into different refreshing display areas, calculating different display characteristics according to the display refreshing areas of the screen of the intelligent wearing watch, calculating the combined refreshing display areas of the screen of the intelligent wearing watch according to the different display characteristics, calculating the refreshing frequency of dynamic partitions according to the combined refreshing display areas of the screen of the intelligent wearing watch, and controlling the refreshing rate of the screen of the intelligent wearing watch by utilizing the refreshing frequency of the dynamic partitions.
When the moment isWhen the associated display coefficient of the intelligent wearable watch screen is smaller than the average value of the associated display coefficients at all different moments in the short-time segment, the intelligent wearable watch screen is describedThe different frame data in the wearable watch screen have strong similar correlation characteristics, so that a dynamic display area is required to be acquired in the intelligent wearable watch screen, and the intelligent wearable watch screen is subjected to partition refreshing adjustment.
As shown in fig. 2, the smart wearable watch screen is divided into three equal parts in the horizontal and vertical directions, wherein the central area of the smart wearable watch screen is recorded as the main refreshing display area、/>、/>、/>And the secondary refresh display area is marked +>、/>、/>、/>Normally, the pictures of the intelligent wearing watch screen are refreshed in the main refreshing display area, and the probability of high-frequency refreshing of the pictures in the secondary refreshing display area is relatively low, so that the intelligent wearing watch screen can be refreshed and displayed according to the positions of different display areas in the intelligent wearing watch screen.
It should be noted that, through roughly dividing the intelligent wearing watch screen into different display areas, the picture is divided into different display areas, in order to accurately obtain the area of refreshing display of the intelligent wearing watch screen at different moments, the display content of the area of the intelligent wearing watch screen needs to be combined for processing.

Typically, the smart wearable watch has its picture focused on the primary refresh display area、/>、/>、/>Therefore, the difference display characteristics of the two different areas can be obtained by calculating the main refreshing display area of the intelligent wearable watch screen through the above method, and as the images displayed in the intelligent wearable watch screen have certain similarity, in the display area of the intelligent wearable watch screen, if the difference display characteristic value calculated between the two different display areas is larger, the similarity of the display images in the corresponding two areas is higher.
