Description

Technical Field

[0001] This invention relates to the field of display control, and more particularly to a TFT-LCD liquid crystal display based on intelligent control. Background Technology

[0002] The power consumption of TFT-LCD liquid crystal displays is a key evaluation factor in the battery life assessment of various mobile terminals. Therefore, the optimization of power consumption of TFT-LCD liquid crystal displays has received widespread attention. The reduction of power consumption of TFT-LCD liquid crystal displays mainly relies on the control of backlight intensity. While reducing the backlight intensity reduces the display's power consumption, it also affects the image display effect. Therefore, it is necessary to adjust the backlight intensity in real time according to the displayed image content. However, if the image content is highly complex or dynamic, it is difficult to ensure the overall coordination of the image and the smoothness of the real-time adjustment during actual real-time control. Therefore, how to reduce the display's power consumption while ensuring the overall coordination and smoothness of the displayed content during actual real-time control of the backlight is a problem that urgently needs to be solved by those skilled in the art.

[0003] Chinese Patent Publication No. CN101290754A discloses a method for reducing energy consumption in a liquid crystal display illuminated by a backlight device, comprising: dimming the backlight and adjusting the image brightness to compensate for the dimmed backlight. A backlight dimming factor is determined based on a limiting point, the limiting point being determined according to the pixel brightness distribution of the image signal. The image brightness is adjusted according to the dimming factor, wherein a first image signal mapping function is used to adjust the pixel brightness below a brightness threshold, and a second image signal mapping function is used to adjust the pixel brightness above the brightness threshold. However, the above technical solution has the following drawbacks: it fails to make targeted optimizations to the actual control process based on the actual complexity of the presented image and the impact of image changes on the real-time backlight control process, resulting in lower overall coordination and smoothness of the presented image during real-time backlight control. Summary of the Invention

[0004] To address this issue, the present invention provides a TFT-LCD liquid crystal display based on intelligent control, which overcomes the problem in the prior art that fails to optimize the actual control process based on the actual complexity and changes in the displayed image, resulting in low overall coordination and smoothness of the displayed image during real-time control of the backlight.

[0005] To achieve the above objectives, the present invention provides a TFT-LCD liquid crystal display based on intelligent control, comprising:

[0006] The display module is used to receive image signals and convert them into visual images;

[0007] The control analysis module, which is connected to the display module, is used to periodically detect the display dynamic index and the display complexity index, and determine the regional prediction strategy within the prediction analysis period based on the display dynamic index and the display complexity index. The regional prediction strategy is to set the predicted brightness parameters for each dynamic control area based on the predictive analysis method or the equalization analysis method.

[0008] The prediction processing module, which is connected to the control analysis module, is used to determine the prediction execution mode based on the trajectory freedom index and the master control execution dynamic index. The prediction execution mode is to determine the prediction key coefficient of each dynamic control region based on the regional key index and the master control execution dynamic index, or to determine the prediction key coefficient of each dynamic control region based on the regional trigger association index and the regional key index.

[0009] The prediction execution module is connected to the display module and the prediction processing module respectively. It is used to determine the estimated brightness parameters of each dynamic control area based on the prediction key coefficient and the reference area key coefficient, and to determine whether to adjust the estimated brightness parameters according to the area prediction difference coefficient.

[0010] The equalization processing module is connected to the display module and the control analysis module respectively. It is used to determine the estimated brightness parameters of each dynamic control area based on the complex parameters and dynamic parameters of the reference area, and to determine whether to adjust the estimated brightness parameters based on the relevant estimated difference coefficient.

[0011] The equalization execution module, which is connected to the equalization processing module, is used to determine the adjustment execution mode based on the execution distribution index and the execution proportion index. The adjustment execution mode is to adjust the estimated brightness parameters of each equalization processing area based on the reference dynamic variation coefficient and the reference estimated difference coefficient, or to determine the equalization control set based on the equalization overlap parameter.

[0012] Furthermore, if the predictive analysis condition of the control analysis module is that the display dynamic index is greater than the preset display dynamic index or the display complexity index is greater than the preset display complexity index, then the prediction processing module will set the predicted brightness parameters for each dynamic control area based on the predictive analysis method.

[0013] Furthermore, if the estimated analysis condition of the control analysis module response is that the display dynamic index is less than or equal to the preset display dynamic index and the display complexity index is less than or equal to the preset display complexity index, then the equalization processing module will set the estimated brightness parameters for each dynamic control area based on the equalization analysis method.

[0014] Furthermore, the prediction processing module responds to the display analysis conditions and determines the prediction execution mode based on the trajectory freedom index and the master control execution dynamic index, so as to determine the prediction key coefficients for each dynamic control region.

[0015] The prediction execution condition of the prediction processing module is that the trajectory freedom index is less than or equal to the preset trajectory freedom index and the master control execution dynamic index is less than or equal to the preset master control execution dynamic index. Then, the prediction key coefficient of each dynamic control area is determined according to the regional key index and the master control execution dynamic index.

[0016] The display analysis conditions are determined by the control analysis module and set by the prediction processing module based on the prediction analysis method for the predicted brightness parameters of each dynamic control area within the predicted analysis period.

[0017] Furthermore, if the prediction execution condition of the prediction processing module is that the trajectory freedom index is greater than the preset trajectory freedom index or the master control execution dynamic index is greater than the preset master control execution dynamic index, then it is determined that the prediction key coefficient of each dynamic control region is determined based on the regional trigger association index and the regional key index, and whether to adjust the prediction key coefficient of each dynamic control region is determined based on the master control execution dynamic index.

[0018] The key adjustment condition for the prediction processing module to respond is that the main control execution dynamic index is greater than the preset main control execution dynamic index. Then, the prediction key coefficient is increased according to the control dynamic parameters.

[0019] The predicted key coefficients are positively correlated with the regional triggering correlation index and the regional key index, respectively, and the increase in the predicted key coefficients is positively correlated with the control dynamic parameters.

[0020] Furthermore, the prediction execution module responds to the prediction setting conditions, determines the predicted brightness parameters of each dynamic control region based on the prediction key coefficient and the reference region key coefficient, and determines whether to adjust the predicted brightness parameters of each dynamic control region according to the region prediction difference coefficient.

[0021] The estimated brightness parameters are positively correlated with the prediction key coefficient and the reference area key coefficient, respectively. The prediction setting condition is that the prediction key coefficients of each dynamic control area have been determined.

[0022] Furthermore, the adjustment evaluation condition for the response of the prediction execution module is that the estimated difference coefficient of the region with a dynamic execution region is greater than the preset estimated difference coefficient, and then it is determined that the estimated brightness parameter of the dynamic execution region should be adjusted based on the evaluation reference difference coefficient.

[0023] The adjustment value of the estimated brightness parameter is negatively correlated with the evaluation reference difference coefficient.

[0024] Furthermore, the equalization processing module responds to the equalization analysis conditions, determines the estimated brightness parameters of each dynamic control region based on the complex parameters and dynamic parameters of the reference region, and determines whether to adjust the estimated brightness parameters of each dynamic control region based on the relevant estimated difference coefficient.

[0025] The adjustment evaluation condition for the equalization processing module response is that the relevant estimated difference coefficient of the dynamic control region is greater than the preset relevant estimated difference coefficient. Then, it is determined that the equalization execution module adjusts the estimated brightness parameter of the dynamic control region and records the dynamic control region as the equalization execution region.

[0026] The equalization analysis conditions are determined by the control analysis module and set by the equalization processing module for the estimated brightness parameters of each dynamic control area based on the equalization analysis method within the estimated analysis period.

[0027] Furthermore, the balanced execution module responds to the balanced adjustment conditions and determines the adjustment execution method based on the execution distribution index and the execution proportion index;

[0028] The adjustment judgment condition for the response of the equalization execution module is that the execution distribution index is less than or equal to the preset execution distribution index and the execution proportion index is less than or equal to the preset execution proportion index. The estimated brightness parameters of each equalization processing area are adjusted according to the reference dynamic variation coefficient and the reference estimated difference coefficient.

[0029] The equalization adjustment condition is that there is a dynamic control region, which is determined by the equalization processing module and adjusted according to the estimated brightness parameters.

[0030] Furthermore, the adjustment judgment condition for the response of the equalization execution module is that the execution distribution index is greater than the preset execution distribution index or the execution proportion index is greater than the preset execution proportion index. Then, the equalization control set is determined according to the equalization overlap parameter, and the estimated brightness parameter of each equalization processing area in each equalization control set is adjusted according to the execution key parameter.

[0031] The adjustment value of the estimated brightness parameter is positively correlated with the key execution parameter.

[0032] Compared with the prior art, the beneficial effects of the present invention are as follows: the technical solution of the present invention determines the regional prediction strategy within the prediction analysis period based on the display dynamic index and the display complexity index, so as to make targeted selections in the process of determining the prediction brightness parameters of the dynamic control area, ensuring the accuracy of the determination results of the prediction brightness parameters of the dynamic control area, and determining the benchmark value of the backlight brightness within the prediction analysis period in advance by predicting the brightness parameters, so as to make initial settings for the subsequent actual control process. The present invention reduces the energy consumption of TFT-LCD liquid crystal display while ensuring the overall coordination and smoothness of the presented picture.

[0033] Furthermore, in this invention, the display dynamic index and display complexity index are used to characterize the degree of change and complexity of the image displayed by the display control target in the recent period, and to assist in the determination of the region prediction strategy. When the display dynamic index or display complexity index is large, the backlight brightness control process will be adjusted more frequently, which will affect the coordination and smoothness of the image presentation. Therefore, the content that may be displayed within the prediction analysis period is predicted, and the predicted brightness parameters are determined accordingly.

[0034] Furthermore, in this invention, when setting the estimated brightness parameters for each dynamic control region based on predictive analysis, the predictive execution method is determined according to the trajectory freedom index and the master control execution dynamic index. This further ensures the accuracy of the determination results for the predictive key coefficients of the dynamic control region. The trajectory freedom index and the master control execution dynamic index determine the degree of limitation of the movement range of the predictive control target within the predictive analysis period, i.e., the richness of different images that may need to be presented. When both the trajectory freedom index and the master control execution dynamic index are small, the predictive key coefficients for each dynamic control region are determined according to the regional key index and the master control execution dynamic index. The regional key index and the master control execution dynamic index characterize the load of each dynamic control region on the presentation of complex images. This invention ensures the accuracy of the determination results for the predictive key coefficients of the dynamic control region, thereby improving the overall coordination and smoothness of the images presented during the actual control process.

[0035] Furthermore, in this invention, when the trajectory freedom index or the master control execution dynamic index is large, the predicted key coefficients of each dynamic control region are determined based on the region trigger correlation index and the region key index. The master control execution dynamic index is used to determine whether to adjust the predicted key coefficients. In such cases, the predicted control target's movement range within the prediction analysis period is relatively wide, potentially leading to abundant key display resources in most dynamic control regions. The region trigger correlation index characterizes the correlation between potentially displayed key display resources, further distinguishing the load on complex image presentation in each dynamic control region within the prediction analysis period. This invention ensures the accuracy of the predicted key coefficients determination results for the dynamic control regions.

[0036] Furthermore, in this invention, when setting the estimated brightness parameters for each dynamic control area based on predictive analysis, the estimated brightness parameters are determined based on the prediction key coefficient and the reference area key coefficient. The adjustment of the estimated brightness parameters is determined based on the area prediction difference coefficient. While ensuring the reliability of the setting results of the estimated brightness parameters for each dynamic execution area, this invention also ensures the balance of the backlight brightness of the overall display control target. This invention improves the overall coordination and smoothness of the image presented during the actual control process.

[0037] Furthermore, in this invention, when both the display dynamic index and the display complexity index are relatively small, the game screen presented in the previous stage before the estimated analysis period is relatively stable. In the actual control of the backlight brightness, the adjustment operation is not frequent, and the impact on the smoothness of the image presentation is small. Therefore, it is necessary to ensure the balance of the estimated brightness parameter setting result with the overall display control target, and determine the adjustment execution method according to the execution distribution index and the execution proportion index, so that the adjustment process of the estimated brightness parameter is more in line with the actual situation, thereby ensuring the effectiveness of the estimated brightness parameter determination result and improving the overall coordination and smoothness of the screen presented in the actual control process.

[0046] Please see Figures 1 to 4 As shown, the present invention provides a TFT-LCD liquid crystal display based on intelligent control, comprising:

[0047] The display module is used to receive image signals and convert them into visual images;

[0048] The control analysis module, which is connected to the display module, is used to periodically detect the display dynamic index and the display complexity index, and determine the regional prediction strategy within the prediction analysis period based on the display dynamic index and the display complexity index. The regional prediction strategy is to set the predicted brightness parameters for each dynamic control area based on the predictive analysis method or the equalization analysis method.

[0049] The prediction processing module, which is connected to the control analysis module, is used to determine the prediction execution mode based on the trajectory freedom index and the master control execution dynamic index. The prediction execution mode is to determine the prediction key coefficient of each dynamic control region based on the regional key index and the master control execution dynamic index, or to determine the prediction key coefficient of each dynamic control region based on the regional trigger association index and the regional key index.

[0050] The prediction execution module is connected to the display module and the prediction processing module respectively. It is used to determine the estimated brightness parameters of each dynamic control area based on the prediction key coefficient and the reference area key coefficient, and to determine whether to adjust the estimated brightness parameters according to the area prediction difference coefficient.

[0051] The equalization processing module is connected to the display module and the control analysis module respectively. It is used to determine the estimated brightness parameters of each dynamic control area based on the complex parameters and dynamic parameters of the reference area, and to determine whether to adjust the estimated brightness parameters based on the relevant estimated difference coefficient.

[0052] The equalization execution module, which is connected to the equalization processing module, is used to determine the adjustment execution mode based on the execution distribution index and the execution proportion index. The adjustment execution mode is to adjust the estimated brightness parameters of each equalization processing area based on the reference dynamic variation coefficient and the reference estimated difference coefficient, or to determine the equalization control set based on the equalization overlap parameter.

[0053] This invention relates to the control of backlight brightness in a TFT-LCD liquid crystal display during gameplay. In games, the image display task is often not fully known, requiring real-time, zoned control of the TFT-LCD backlight brightness based on the image content presented at each moment. This reduces power consumption while maintaining image quality. In this invention, the display module is a TFT-LCD, and each pixel has a thin-film transistor. Light emitted from the backlight passes through optical components and enters the liquid crystal layer. The thin-film transistor generates voltage, controlling the rotation direction of the liquid crystal molecules, thereby adjusting the amount of light transmitted and creating different pixel brightness levels. Adjusting the backlight intensity effectively reduces power consumption. The TFT-LCD under zoned real-time control is designated as the display control target, and the screen area corresponding to the display control target is divided into several sections. Rectangular areas with the same area are denoted as dynamic control areas. Users can set the number of dynamic control areas according to actual working conditions. The higher the user's requirements for the backlight control quality of the display control target, the larger the number of dynamic control areas. After the estimated brightness parameters of each dynamic control area are determined, the reference backlight brightness of each dynamic control area is determined according to the estimated brightness parameters. The reference backlight brightness is positively correlated with the estimated brightness parameters. During the backlight brightness adjustment process of each dynamic control area within the estimation analysis period, the reference backlight brightness of each dynamic control area is adjusted according to the actual displayed image. This can ensure the timeliness of the backlight brightness adjustment results and the image presentation effect while reducing the power consumption of the display control target. How to adjust the reference backlight brightness of each dynamic control area according to the actual displayed image is a topic that is already known to those skilled in the art and will not be elaborated here.

[0054] This invention utilizes several backlight control records. Each backlight control record records at least one instance of real-time adjustment of the backlight intensity for the display control target, including display dynamic index, display complexity index, trajectory freedom index, master control execution dynamic index, area prediction difference coefficient, area interval parameter, related prediction difference coefficient, execution distribution index, execution proportion index, and balance overlap parameter. Each backlight control record also has a corresponding pass / fail marker, which indicates whether the backlight adjustment quality for the display control target meets the user's requirements.

[0055] Specifically, if the predicted analysis condition of the control analysis module is that the display dynamic index is greater than the preset display dynamic index or the display complexity index is greater than the preset display complexity index, then the prediction processing module will set the predicted brightness parameters for each dynamic control area based on the prediction analysis method.

[0056] Specifically, if the predicted analysis condition of the control analysis module is that the display dynamic index is less than or equal to the preset display dynamic index and the display complexity index is less than or equal to the preset display complexity index, then the equalization processing module will set the predicted brightness parameters for each dynamic control area based on the equalization analysis method.

[0057] In this invention, a display analysis cycle is applied, the duration of which can be determined by the user. The higher the user's requirements for the backlight control quality of the display control target, the shorter the duration of the display analysis cycle. A value for the duration of the display analysis cycle is provided, which is 1 minute. At the end of each display analysis cycle, the display dynamic index and display complexity index are detected. Since the image content to be presented during the actual game is not fully known, it is impossible to pre-set the backlight brightness according to the image to be displayed at each moment. Therefore, it is necessary to make targeted predictions for the image to be presented and determine the targeted prediction process based on the actual display situation.

[0058] If the current time is the end time of a display analysis cycle, the display dynamic index and display complexity index of that display analysis cycle are detected to determine the region prediction strategy within the predicted analysis cycle. The image frames displayed at each time point within the display analysis cycle are obtained and recorded as display analysis images. The display dynamic index is the average of the display dynamic parameters of each adjacent display image combination within the display analysis cycle. If there are two display analysis images whose corresponding times do not have other display analysis images, these two display analysis images are recorded as an adjacent display image combination. For a single adjacent display image combination, the display dynamic parameter is equal to the value of the display dynamic parameters within that adjacent display image combination. The average absolute value of the difference between the pixel brightness values ​​at the same pixel position in two display analysis images / the maximum pixel brightness value in the two display analysis images within the adjacent display image combination; the display complexity index is the average value of the image complexity parameters of each display analysis image within the display analysis period; for a single display analysis image, the image complexity parameter = (maximum brightness value of each pixel in the display analysis image - minimum brightness value of each pixel in the display analysis image) / maximum brightness value of each pixel in each display analysis image within the display analysis period; the estimated analysis period is the display analysis period starting from the current time.

[0059] The values ​​of the preset display dynamic index and the preset display complexity index can be determined by the user according to the actual working scenario. For example, the user can set them based on the backlight control records. The higher the user's requirements for the backlight control quality of the display control target, the smaller the value of the preset display dynamic index and the smaller the value of the preset display complexity index. A method for determining the value of the preset display dynamic index is provided, in which the backlight control records set based on the equalization analysis method for the estimated brightness parameters of each dynamic control area are recorded as display reference records, and the average value of the display dynamic index in the display reference records that meet the user's requirements for the backlight control quality of the display control target is recorded as the preset display dynamic index. A method for determining the value of the preset display complexity index is provided, in which the average value of the display complexity index in the display reference records that meet the user's requirements for the backlight control quality of the display control target is recorded as the preset display complexity index.

[0060] Specifically, the prediction processing module responds to the display analysis conditions, determines the prediction execution mode based on the trajectory freedom index and the master control execution dynamic index, and determines the prediction key coefficients for each dynamic control region.

[0061] The prediction execution condition of the prediction processing module is that the trajectory freedom index is less than or equal to the preset trajectory freedom index and the master control execution dynamic index is less than or equal to the preset master control execution dynamic index. Then, the prediction key coefficient of each dynamic control area is determined according to the regional key index and the master control execution dynamic index.

[0062] The display analysis conditions are determined by the control analysis module and set by the prediction processing module based on the prediction analysis method for the predicted brightness parameters of each dynamic control area within the predicted analysis period.

[0063] If the display dynamic index is greater than the preset display dynamic index or the display complexity index is greater than the preset display complexity index, it indicates that the degree of change of the displayed image or the complexity of the displayed image is relatively high in the previous stage of the estimated analysis period. In the process of controlling the backlight brightness of different areas in real time according to the displayed content, the degree of change and complexity of the image can easily lead to frequent adjustments in the control of backlight brightness, which will affect the coordination and smoothness of the image presentation and affect the user experience. In this case, it is necessary to predict the image situation to be presented in the estimated analysis period, and then determine the prediction key coefficient of each dynamic control area to characterize the backlight brightness requirement of each dynamic control area in the estimated analysis period. The prediction execution method is determined according to the trajectory freedom index and the master control execution dynamic index.

[0064] The specific target whose position change is achieved through the user's operation of the displayed control target during the game is recorded as the predicted control target. The trajectory freedom index and the master control execution dynamic index are detected. In the process of determining the trajectory freedom index and the master control execution dynamic index, the position change should be limited to a plane parallel to the actual game map. The trajectory freedom index is the sum of the coverage angle parameters of each control execution trajectory of the predicted control target at the current moment / 360°. The control execution trajectory is the trajectory that the predicted control target can achieve position change at the current position. For a single execution control trajectory, the coverage angle parameter is the maximum angle value of the angle formed between the current position of the predicted control target and any position in the execution control trajectory - the minimum angle value of the angle formed between the current position of the predicted control target and any position in the execution control trajectory. In the process of determining the angle, the current position of the predicted control target is taken as the origin, and the horizontal direction to the right is taken as the baseline.

[0065] This invention applies a control monitoring cycle, the duration of which can be determined by the user. The higher the user's requirements for the backlight adjustment quality of the display control target, the shorter the control monitoring cycle. One possible value for the control monitoring cycle length is 2 seconds. At the end of each control monitoring cycle, the acceleration of the predicted control target is detected. The main control execution dynamic index is the sum of the control movement parameter and the control dynamic parameter. The control movement parameter = the average value of the predicted acceleration of the control target obtained in each display analysis cycle preceding the estimated analysis cycle / the maximum value of the predicted acceleration of the control target obtained in each display analysis cycle preceding the estimated analysis cycle. The control dynamic parameter... s represents the number of times the acceleration of the predictive control target is detected in the previous display analysis period of the prediction analysis period, dt represents the value of the acceleration of the predictive control target obtained in the t-th time in the previous display analysis period of the prediction analysis period, and L0 represents the average value of the acceleration values ​​of the predictive control target obtained in each time in the previous display analysis period of the prediction analysis period.

[0066] The values ​​of the preset trajectory freedom index and the preset master control execution dynamic index can be determined by the user according to the actual working scenario. For example, the user can set them according to the backlight control records. A method for determining the value of the preset trajectory freedom index is provided, in which the backlight control records that determine the predicted key coefficients of each dynamic control area based on the regional key index and the master control execution dynamic index are recorded as the prediction reference records, and the maximum value of the trajectory freedom index in the prediction reference records that meets the user's backlight control quality requirements for the display control target is recorded as the preset trajectory freedom index. A method for determining the value of the preset master control execution dynamic index is provided, in which the maximum value of the master control execution dynamic index in the prediction reference records that meets the user's backlight control quality requirements for the display control target is recorded as the preset master control execution dynamic index.

[0067] When the trajectory freedom index is less than or equal to the preset trajectory freedom index and the master control execution dynamic index is less than or equal to the preset master control execution dynamic index, it indicates that the movement range of the predicted control target within the prediction analysis period is relatively limited. Therefore, by predicting the content that may be triggered within the prediction analysis period and judging the prediction key coefficient of each dynamic control area, the game image information triggered by the predicted control target at any position within the prediction processing range is obtained. For a single position, the triggered game image information is the dynamic control area involved by each key display resource that can be triggered when the target is at that position. The key display resource is the triggering resource that the predicted control target needs to complete when it is at that position. The triggering resource is the non-player controlled character that needs to be displayed after meeting the predetermined conditions. How to obtain the key display resources that can be triggered at each position is a content that is easy for those skilled in the art to understand and will not be elaborated here. The prediction processing range is a circular area with the current position as the center and the prediction processing length as the radius. The prediction processing length is positively correlated with the master control execution dynamic index.

[0068] For a single dynamic control region, the predicted critical coefficient is positively correlated with the region richness reference value. The region richness reference value is the sum of the region critical index and the master control execution dynamic index. The region critical index is calculated as the number of critical display resources involved in the dynamic control region within the estimated analysis period / the number of critical display resources involved in the display control target within the estimated analysis period. By using the region critical index and the master control execution dynamic index, the burden on complex resource presentation and the changes in the image of each dynamic control region within the estimated analysis period are determined, so as to ensure that the setting of the estimated brightness parameters for the dynamic control region can meet the actual display quality requirements.

[0069] Specifically, if the prediction execution condition of the prediction processing module is that the trajectory freedom index is greater than the preset trajectory freedom index or the master control execution dynamic index is greater than the preset master control execution dynamic index, then it is determined that the prediction key coefficient of each dynamic control area is determined according to the regional trigger association index and the regional key index, and whether to adjust the prediction key coefficient of each dynamic control area is determined according to the master control execution dynamic index.

[0070] The key adjustment condition for the prediction processing module to respond is that the main control execution dynamic index is greater than the preset main control execution dynamic index. Then, the prediction key coefficient is increased according to the control dynamic parameters.

[0071] The predicted key coefficients are positively correlated with the regional triggering correlation index and the regional key index, respectively, and the increase in the predicted key coefficients is positively correlated with the control dynamic parameters.

[0072] When the trajectory freedom index is greater than the preset trajectory freedom index or the master control execution dynamic index is greater than the preset master control execution dynamic index, it indicates that the movement range of the predicted control target within the prediction analysis period is relatively wide. Therefore, when predicting the content that may be triggered within the prediction analysis period, the triggering resources involved are too numerous. Further analysis of the correlation between different triggering resources is needed to ensure the effectiveness of the determined prediction key coefficient. For a single dynamic control area, the prediction key coefficient is positively correlated with the effective triggering reference value of the area. The effective triggering reference value of the area is the sum of the area triggering correlation index and the area key index. The area triggering correlation index = the maximum value of the triggering correlation parameter of each control execution trajectory within the prediction analysis period / the number of key display resources involved in the dynamic control area within the prediction analysis period. For a single control execution trajectory, the triggering correlation parameter is the number of key display resources involved in the dynamic control area within the prediction analysis period whose corresponding positions are located within the control execution trajectory when they are determined to be key display resources.

[0073] Specifically, the prediction execution module responds to the prediction setting conditions, determines the predicted brightness parameters of each dynamic control area based on the prediction key coefficient and the reference area key coefficient, and determines whether to adjust the predicted brightness parameters of each dynamic control area according to the area prediction difference coefficient.

[0074] The estimated brightness parameters are positively correlated with the prediction key coefficient and the reference area key coefficient, respectively. The prediction setting condition is that the prediction key coefficients of each dynamic control area have been determined.

[0075] Specifically, for a single dynamic control area, the estimated brightness parameter and the display reference coefficient are positively correlated. The display reference coefficient = the predicted critical coefficient of the dynamic control area × the reference area focus coefficient. The reference area focus coefficient is the average of the area focus coefficients of each display analysis cycle within the reference evaluation phase of the estimated analysis cycle. The end time of the reference evaluation phase is the start time of the estimated analysis cycle. The duration of the reference evaluation phase can be set by the user according to actual needs. The higher the user's requirements for the backlight control quality of the display control target, the longer the duration of the reference evaluation phase. One possible value for the duration of the reference evaluation phase is ten times the duration of the display analysis cycle. For a single display analysis cycle, the area focus coefficient = the maximum value of the backlight brightness of the dynamic control area reached within the display analysis cycle / the maximum value that the backlight brightness of the dynamic control area can reach.

[0076] Specifically, the adjustment evaluation condition for the response of the prediction execution module is that if the estimated difference coefficient of the region with a dynamic execution area is greater than the preset estimated difference coefficient, then it is determined that the estimated brightness parameter of the dynamic execution area should be adjusted based on the evaluation reference difference coefficient.

[0077] The adjustment value of the estimated brightness parameter is negatively correlated with the evaluation reference difference coefficient.

[0078] Specifically, for a single dynamic execution region that has completed the determination of the estimated brightness parameters, the dynamic execution region is denoted as the target evaluation region. The region estimation difference coefficient is the average value of the estimated brightness difference values ​​of each dynamic execution region in the evaluation execution set of the target evaluation region / the maximum value of the estimated brightness difference values ​​of each dynamic execution region in the evaluation execution set of the target evaluation region. The evaluation execution set is a set of several dynamic execution regions. The region interval parameter of each dynamic execution region in the evaluation execution set is less than the preset region interval parameter. For any dynamic execution region in the evaluation execution set, the estimated brightness difference value is the absolute value of the difference between the estimated brightness parameter of the dynamic execution region and the estimated brightness parameter of the target evaluation region. The region interval parameter is the distance between the centroid of the corresponding range of the dynamic execution region and the center point of the corresponding range of the target evaluation region in the evaluation execution set.

[0079] The values ​​of the preset area estimated difference coefficient and the preset area interval parameter can be determined by the user according to the actual working scenario. For example, the user can set them according to the backlight control record. The higher the user's requirements for the backlight adjustment quality of the display control target, the smaller the value of the preset area estimated difference coefficient and the smaller the value of the preset area interval parameter. A method for determining the value of the preset area estimated difference coefficient is provided, in which the backlight control record that adjusts the estimated brightness parameter of the dynamic execution area based on the evaluation reference difference coefficient is recorded as the reference display adjustment record, and the average value of the area estimated difference coefficient of each dynamic execution area in the reference display adjustment record that meets the user's backlight adjustment quality requirements for the display control target is recorded as the preset area estimated difference coefficient. A method for determining the value of the preset area interval parameter is provided, in which the maximum value of the area interval parameter of each dynamic execution area in the evaluation execution set of the backlight control record that meets the user's backlight adjustment quality requirements for the display control target is recorded as the preset area interval parameter.

[0080] If the estimated difference coefficient of a dynamic control region is greater than the preset estimated difference coefficient, it indicates that there is a significant difference between the estimated brightness parameters determined by this dynamic control region and the estimated brightness parameters of similar dynamic control regions. To avoid excessive differences in backlight brightness between different dynamic control regions and to ensure the actual image presentation effect, it is necessary to adjust the estimated brightness parameters of the dynamic control region. For a dynamic control region where the estimated difference coefficient is greater than the preset estimated difference coefficient, the evaluation reference difference coefficient is the average of the estimated brightness difference values ​​of each dynamic execution region within the evaluation execution set of this dynamic control region. The dominant difference index of this dynamic control region is detected. n is the number of dynamic execution regions within the evaluation execution set of the dynamic control region, y is the estimated brightness parameter of the dynamic control region, and yi is the estimated brightness parameter of the i-th dynamic execution region within the evaluation execution set of the dynamic control region. If the dominant difference index of the dynamic control region is greater than 0, the estimated brightness parameter of the dynamic execution region is reduced. If the dominant proportion trend value of the dynamic control region is less than or equal to 0, the estimated brightness parameter of the dynamic execution region is increased.

[0081] Specifically, the equalization processing module responds to the equalization analysis conditions, determines the estimated brightness parameters of each dynamic control region based on the complex parameters and dynamic parameters of the reference region, and determines whether to adjust the estimated brightness parameters of each dynamic control region based on the relevant estimated difference coefficient.

[0082] The adjustment evaluation condition for the equalization processing module response is that the relevant estimated difference coefficient of the dynamic control region is greater than the preset relevant estimated difference coefficient. Then, it is determined that the equalization execution module adjusts the estimated brightness parameter of the dynamic control region and records the dynamic control region as the equalization execution region.

[0083] The equalization analysis conditions are determined by the control analysis module and set by the equalization processing module for the estimated brightness parameters of each dynamic control area based on the equalization analysis method within the estimated analysis period.

[0084] If the display dynamic index is less than or equal to the preset display dynamic index and the display complexity index is less than or equal to the preset display complexity index, it indicates that the degree of change and load of the displayed image in the previous stage of the estimated analysis period are both low. In other words, the picture presented in the game is relatively stable. The actual control operation of the backlight brightness is not frequent and has little impact on the smoothness of the image presentation. Therefore, only the coordination of the picture presentation is evaluated and further adjustments are made.

[0085] When setting the estimated brightness parameters for each dynamic control region based on the equalization analysis method, for a single dynamic control region, the estimated brightness parameter and the region reference coefficient are positively correlated. The region reference coefficient is the sum of the reference region complexity parameter and the reference region dynamic parameter for that dynamic control region. A portion of the images within the range corresponding to that dynamic control region in each display analysis image within the previous display analysis cycle is recorded as the equalization reference image for that dynamic control region. The reference region complexity coefficient is the average of the region complexity parameters of each equalization reference image, and the reference region dynamic parameter is the average of the region dynamic parameters of the combination of adjacent reference images. For a single equalization reference image, the region... Complex parameter = (maximum brightness value of each pixel in the equalization reference image - minimum brightness value of each pixel in the equalization reference image) / maximum brightness value of each pixel in each display analysis image within the equalization reference image. If there are two equalization reference images and no other equalization reference images exist between them, these two equalization reference images are recorded as an adjacent reference image combination. For a single adjacent reference image combination, the region dynamic parameter = the average of the absolute values ​​of the differences between the pixel brightness values ​​at the same pixel position in the two equalization reference images within the adjacent reference image combination / the maximum value of the pixel brightness values ​​in the two equalization reference images within the adjacent reference image combination. The relevant prediction difference coefficient... e represents the number of dynamic execution regions within the evaluation execution set of the target evaluation region, Lf represents the estimated brightness parameter of the f-th dynamic execution region within the evaluation execution set of the target evaluation region, and L0 represents the average value of the estimated brightness parameters of each dynamic execution region within the evaluation execution set of the target evaluation region.

[0086] The value of the preset related estimated difference coefficient can be determined by the user according to the actual working scenario. For example, the user can set it according to the backlight control record. The higher the user's requirements for the backlight control quality of the display control target, the smaller the value of the preset related estimated difference coefficient. A method for determining the value of the preset related estimated difference coefficient is provided, in which the backlight control record that adjusts the estimated brightness parameters of the dynamic control area under the equalization analysis condition is recorded as the equalization control record, and the minimum value of the related estimated difference coefficient in the equalization control record that meets the user's requirements for the backlight control quality of the display control target is recorded as the preset related estimated difference coefficient.

[0087] Specifically, the balanced execution module responds to the balanced adjustment conditions and determines the adjustment execution method based on the execution distribution index and the execution proportion index;

[0088] The adjustment judgment condition for the response of the equalization execution module is that the execution distribution index is less than or equal to the preset execution distribution index and the execution proportion index is less than or equal to the preset execution proportion index. The estimated brightness parameters of each equalization processing area are adjusted according to the reference dynamic variation coefficient and the reference estimated difference coefficient.

[0089] The equalization adjustment condition is that there is a dynamic control region, which is determined by the equalization processing module and adjusted according to the estimated brightness parameters.

[0090] Wherein, the execution distribution index is the average number of equal processing regions existing in the evaluation execution set of each equal processing region, and the execution proportion index is equal to the number of equal processing regions existing in the display control target / the number of dynamic control regions existing in the display control target. The values ​​of the preset execution distribution index and the preset execution proportion index can be determined by the user according to the actual working scenario. For example, the user can set them according to the backlight control record. A method for determining the value of the preset execution distribution index is provided, in which the backlight control record that adjusts the estimated brightness parameters of each equal processing region according to the reference dynamic variation coefficient and the reference estimated parameter is recorded as the equal control reference record, and the maximum value of the execution distribution index in the equal control reference record that meets the user's backlight control quality requirements for the display control target is recorded as the preset execution distribution index. A method for determining the value of the preset execution proportion index is provided, in which the maximum value of the execution proportion index in the equal control reference record that meets the user's backlight control quality requirements for the display control target is recorded as the preset execution proportion index.

[0091] If the execution distribution index is less than or equal to the preset execution distribution index and the execution proportion index is less than or equal to the preset execution proportion index, it indicates that there are few dynamic control areas in the display control target that need to be balanced, and the distribution of the balanced processing areas is relatively scattered. Therefore, by processing a single balanced processing area, the overall balance of the screen can be improved. For a single balanced processing area, the reference dynamic variation coefficient = (maximum value of the regional dynamic parameters of each adjacent reference image combination - minimum value of the regional dynamic parameters of each adjacent reference image combination) / average value of the regional dynamic parameters of each adjacent reference image combination. The reference estimated difference coefficient is the absolute value of the regional estimated difference coefficient. m is the number of dynamic execution regions within the evaluation execution set of the equalization processing region, p is the estimated brightness parameter of the equalization processing region, and pj is the estimated brightness parameter of the j-th dynamic execution region within the evaluation execution set of the equalization processing region. If the regional estimated difference coefficient of the equalization processing region is greater than 0, the estimated brightness parameter of the equalization processing region is decreased; if the regional estimated difference coefficient of the equalization processing region is less than or equal to 0, the estimated brightness parameter of the equalization processing region is increased. The adjusted value of the estimated brightness parameter is positively correlated with the independent control parameter, which is equal to the reference estimated difference coefficient and the reference dynamic variation coefficient. This ensures that the backlight brightness of different regions is balanced while taking into account the actual display requirements of the screen during the adjustment process.

[0092] Specifically, the adjustment judgment condition of the equalization execution module response is that the execution distribution index is greater than the preset execution distribution index or the execution proportion index is greater than the preset execution proportion index. Then, the equalization control set is determined according to the equalization overlap parameter, and the estimated brightness parameter of each equalization processing area in each equalization control set is adjusted according to the execution key parameter.

[0093] The adjustment value of the estimated brightness parameter is positively correlated with the key execution parameter.

[0094] If the execution distribution index is greater than the preset execution distribution index or the execution ratio index is greater than the preset execution ratio index, it indicates that there are many dynamic control areas of the display control target that need to be balanced or the distribution of the balanced processing areas is relatively concentrated. It is necessary to adjust according to the overall situation of the main concentrated areas of the balanced processing areas to ensure the overall balance of the screen.

[0095] The equalization control set is divided according to the equalization processing area where the display control target exists. The equalization overlap parameter of each equalization control set is greater than the preset equalization overlap parameter. For a single equalization control set, the equalization overlap parameter is the average number of equalization processing areas in the equalization control set within the evaluation execution set of each equalization processing area in the equalization control set. For any equalization processing area in the equalization control set, the adjustment value of the estimated brightness parameter is positively correlated with the execution key parameter. The execution key parameter = the relevant estimated difference coefficient of the equalization processing area / the relevant estimated difference coefficient of each equalization processing area in the equalization control set. If the area estimated difference coefficient of the equalization processing area is greater than 0, the estimated brightness parameter of the equalization processing area is decreased. If the area estimated difference coefficient of the equalization processing area is less than or equal to 0, the estimated brightness parameter of the equalization processing area is increased.

[0096] The value of the preset equalization overlap parameter can be determined by the user according to the actual working scenario. For example, the user can set it according to the backlight control record. The higher the user's requirements for the backlight control quality of the display control target, the larger the value of the preset equalization overlap parameter. A method for determining the value of the preset equalization overlap parameter is provided, which records the minimum value of the equalization overlap parameter of each equalization control set in the backlight control record that meets the user's requirements for the backlight control quality of the display control target as the preset equalization overlap parameter.
