Fig. 1 is a schematic flowchart of a display control method according to an embodiment of the present application, and as shown in fig. 1, the flowchart may include steps 101 to 103:
step 101, obtaining first information.
The first information comprises display brightness of the display device when the display device displays the first data at the first moment.
In one embodiment, the first data may include static display data, such as static displayed text data, picture data, and the like; illustratively, the first data may include dynamic display data such as scrolling text data, video data, blinking controls, and time data, among others.

Illustratively, the first information may be obtained in real time by detecting display brightness of the display device; it may also be determined according to the display brightness of the third data displayed at the third time, that is, the first information may be predetermined; wherein the third time may include a time before the first time.
Step 102, determining second information based on the first information.
The second information comprises display brightness when the display device displays the second data at the second moment; the second time includes at least a next time to the first time.
In one embodiment, the second time may include a time adjacent to the first time, for example, during the playing of the video, the first data may be first frame data of the video data at the first time, and the second data may be second frame data of the video data at a time next to the first time; for example, the second time may include a time not adjacent to the second time, for example, when the first time displays the first data, the display screen is in an active state, and when the display screen is in a dormant state for a period of time after the first time, the display screen is reactivated at the second time, and when the second time is not adjacent to the first time.
In one embodiment, the type of the second data may be the same as the type of the first data, for example, the first data and the second data are both picture data; for example, the type of the second data may be different from the type of the first data, such as the first data being picture data and the second data being text data.
For example, the second information may be determined by any one of the following:
adjusting the first information according to the first type and the second type so as to determine second information; wherein the first type may be a type of first data, and the second type may be a type of second data; for example, if the first type is the same as the second type, the first information is adjusted to a first degree; if the first type is different from the second type, adjusting the first information to a second degree; wherein the first degree is different from the second degree.
Adjusting the first information according to the first quantity and the second quantity so as to determine second information; wherein the first amount may comprise a data amount and/or resolution of the first data and the second amount may comprise a data amount and/or resolution of the second data; if the absolute value of the difference between the first quantity and the second quantity is smaller than or equal to a preset threshold value, adjusting the first information to a third degree; if the absolute value of the difference between the first quantity and the second quantity is larger than a preset threshold value, adjusting the first information to a fourth degree; wherein the third degree and the fourth degree may be different.
According to the similarity degree of the first data and the second data, the first information is adjusted so as to determine the second information; for example, if the first data is the same as the second data, the second information may be the same as the first information; if the first data is different from the second data, the first information may be adjusted to determine the second information.
And 103, controlling the display device to display the second data based on the second information.
As can be seen from the above, the display control method provided in the embodiment of the present application can determine the second information based on the first information after acquiring the first information, which is the display brightness of the display device when displaying the first data at the first time, and control the display device to display the second data based on the second information; the second information comprises display brightness when the display device displays the second data at the second moment; the second time includes at least a next time to the first time.
Therefore, according to the display control method provided by the embodiment of the application, under the condition that the first time is the historical time and the second time is the current time, the current brightness of the current data displayed by the display device can be determined according to the historical brightness of the display device when the historical data is displayed, so that smooth adjustment from the historical brightness to the current brightness is realized, the probability of drastic change of the display brightness of the display screen is reduced, and the data display effect of the display screen is improved.
Based on the foregoing embodiment, in the display control method provided in the embodiment of the present application, the second information includes display brightness of at least a partial region when the display device displays the second data.
In one embodiment, the second information may include display brightness of a partial region when the second data is displayed, for example, a display region having a certain area with a midpoint of the display device as a center point, or a display region having a certain area and including a corner point of the display device; illustratively, the at least partial region may comprise the entire display area of the display device.
For example, the second information may be determined according to data display requirements, personal use habits of the user, a type of the second data, a resolution of the second data, a data amount of the second data, a number of windows currently displayed in the display device, and a window hierarchical relationship of at least one window displayed in the display device.
For example, if the second data is image data, and if the second data includes a target object set by a user, at least part of the area may include an area for displaying the target object, for example, under a condition that the target object is a mountain range, display luminance of a pixel area including the mountain range in the second data may be adjusted, and display luminance of a pixel area excluding the mountain range in the second data may be maintained as default luminance.
For example, whether to adjust the entire display area of the display device may be determined according to the type of the display device; for example, if the display device is an LCD, the second information may include an entire display area of the display device; if the display device is an OLED, the second information may include a partial display area or an entire display area of the display device.
For example, determining the second information based on the first information may be implemented by the process shown in fig. 2, where fig. 2 is a schematic view of the process for determining the second information provided in the embodiment of the present application, and as shown in fig. 2, the process may include steps 201 to 203:
step 201, a first brightness and a second brightness are obtained.
Wherein the first brightness comprises a brightness of at least a portion of the pixel region of the first data; the second brightness includes a brightness of at least a portion of the pixel region of the second data.
For example, the first brightness and the second brightness may be determined according to data characteristics of data included in the first data and the second data, that is, the first brightness and the second brightness may be determined before the first data and the second data are displayed on the display device.
Illustratively, the first brightness br is under the condition that the first data and the second data both include n pixel points A Can be obtained by the formula (1):

in the formula (1), the reaction mixture is,
Figure BDA0003785171110000082
representing the lightness of the ith pixel in the first dataIt can be calculated by equation (2):
Figure BDA0003785171110000091
in the equation (1), i represents the number or number of pixels in the first data,
Figure BDA0003785171110000092
RGB values that may represent the ith pixel of the first data; illustratively, br is the case where the value of i traverses 1 to n A Can represent the overall brightness of the first data, and the value of i is [1,n]In the case of a proper subset of (1), br A The brightness of the partial area of the first data may be represented.
Illustratively, the second brightness br B Can be obtained by the formula (3):
Figure BDA0003785171110000093
in the formula (3), the reaction mixture is,
Figure BDA0003785171110000094
the brightness of the ith pixel in the second data can be represented, which can be calculated by equation (4):
Figure BDA0003785171110000095
in equation (4), i represents the number or number of pixels in the second data,
Figure BDA0003785171110000096
RGB values that may represent the ith pixel of the second data; illustratively, br is the case where the value of i traverses 1 to n B The overall lightness of the first data can be represented, and the value of i is [1,n ]]In the case of proper subset of (1), br B The brightness of the partial area of the first data may be represented.
For example, the brightness of different colors may be different, and in practical applications, the brightness of different colors may be as follows: br (black-0,0,0) =0.000000; br (indigo-0,0, 255) =0.328424; br (red-255,0,0) =0.547373; br (purple-255,0, 255) =0.622073; br (green-0,255,0) =0.821060; br (aqua blue-0, 255, 255) =0.869083; br (yellow-255, 255,0) =0.959792; br (white-255, 255, 255) =1.000000.
Step 202, processing the first information based on the first brightness and the second brightness to obtain third information.
For example, the degree of adjustment of the first information may be determined based on a trend of change between the first brightness and the second brightness, and the first information may be adjusted based on the degree of adjustment, thereby obtaining the third information; for example, if the second brightness is a brightness enhancement trend relative to the first brightness, the first information may be subjected to enhancement processing to obtain third information; if the second lightness has a tendency of lightness change with respect to the first lightness, the first information may be subjected to a weakening process to obtain third information.
For example, the third information may include a weighting result obtained by weighting the second information.
And step 203, processing the third information to determine second information.
Illustratively, the second information may be implemented by any one of:
the third information is subjected to weighting processing, and the result of the weighting processing is determined as the second information.
Based on a difference between the first brightness and the second brightness, a weight coefficient is determined, the third information is weighted according to the weight coefficient, and a result of the weighting is determined as the second information.
As can be seen from the above, in the display control method provided in the embodiment of the present application, after the first brightness and the second brightness are obtained, the first information can be processed based on the first brightness and the second brightness to obtain the third information, and the third information is processed to determine the second information, where the first brightness includes the brightness of at least part of the pixel region of the first data; the second brightness includes a brightness of at least a portion of the pixel region of the second data.
Therefore, the first lightness and the second lightness can represent the pixel characteristics of the first data and the second data, so that the process of processing the first information based on the first lightness and the second lightness to obtain the third information reflects the adjustment of the historical display brightness of the display screen according to the pixel characteristics of the data displayed by the display screen, the second information can be kept smooth relative to the first information, the probability of sudden brightness change of the second data displayed by the display device is reduced, the second information can carry the lightness characteristics of the second data, and the display effect of the second data can be improved by the second information in a targeted manner.
Based on the foregoing embodiment, the display control method provided in the embodiment of the present application may be implemented by processing the first information based on the first brightness and the second brightness to obtain the third information, and by:
determining a brightness difference between the first brightness and the second brightness; and if the lightness difference is greater than or equal to the specified threshold value, processing the first information based on the first lightness and the second lightness to obtain third information.
For example, if the brightness difference is less than the specified threshold, then the processing of the first information at the second brightness from the first brightness to obtain the third information may not be performed.
In one embodiment, the designated threshold may be adjusted according to at least one of personal usage habits of a user, data display performance of the display device, application scenarios of display data of the display device, ambient light brightness, and ambient light temperature; illustratively, the specified threshold may also be manually set by the user.
In one embodiment, the lightness difference may be embodied by an absolute value of a difference between the first lightness and the second lightness; for example, the lightness difference may be embodied in a matrix, where the matrix may include the lightness differences between n pixel points in the first data and n pixel points in the second data; for example, the brightness difference may include an overall brightness difference between the first data and the second data, that is, a brightness difference between n pixel points in the first data and n pixel points in the second data; for example, the brightness difference may include brightness differences between partial regions in the first data and partial regions in the second data, for example, brightness differences between k pixel point to k + m pixel point in the first data and k pixel point to k + m pixel point in the second data, where k and m may be integers greater than or equal to 0, and k + m may be integers greater than or equal to 0 and less than n.
As can be seen from the above, in the display control method provided in the embodiment of the present application, when the brightness difference between the first brightness and the second brightness is determined and the brightness difference is greater than or equal to the specified threshold, the first information is processed to obtain the third information based on the first brightness and the second brightness.
Therefore, the display control method provided by the embodiment of the application processes the first information based on the first brightness and the second brightness when the brightness difference between the first brightness and the second brightness is determined to be greater than or equal to the specified threshold value, so that strict control over the processing of the first information is realized; and when the lightness difference between the first lightness and the second lightness is larger than or equal to the specified threshold value, the first information is processed based on the first lightness and the second lightness, so that the obvious lightness difference between the first lightness and the second lightness can be fully compensated in the processing process of the first information and the third information obtained by processing the first information, and the display effect of the second data is further improved.
Based on the foregoing embodiment, the display control method provided in the embodiment of the present application processes the first information based on the first brightness and the second brightness to obtain the third information, and can also be implemented by:
brightness contrast information of the first brightness and the second brightness is determined, and the first information is processed based on the brightness contrast information to obtain third information.
For example, the brightness contrast information may include contrast information between brightness of all pixel points of the first data and brightness of all pixel points of the second data; for example, the brightness contrast information may further include contrast information between brightness of a first set of pixel points in the first data and brightness of a second set of pixel points in the second data, where the first set of pixel points may correspond to the second set of pixel points; illustratively, the numbers of the pixels corresponding to the first pixel point set and the second pixel point set may be the same, for example, the first pixel point set includes k to k + m pixels in the first data, and the second pixel point set may include k to k + m pixels in the second data; for example, the display area corresponding to the first pixel point set and the display area corresponding to the second pixel point set may be the same; for example, the display object corresponding to the first pixel point set and the real object corresponding to the second pixel point set may be the same.
For example, the first information may be weighted based on the brightness contrast information, thereby obtaining the third information.
Illustratively, the third information x may be calculated by equation (5):
Figure BDA0003785171110000121
wherein α may be a brightness when the display screen displays the first data, that is, the first information, that is, a default brightness when the display screen displays the second data before the display brightness of the second data is not adjusted; for example, α may be a display luminance preset in the electronic device, or may be a display luminance determined based on third data displayed at a third time, that is, first information.
As can be seen from the above, in the display control method provided in the embodiment of the present application, after the brightness contrast information between the first brightness and the second brightness is determined, the first information can be processed based on the brightness contrast information, so as to obtain the third information.
Therefore, the brightness contrast information can show not only the trend of change of the second brightness relative to the first brightness, but also the change of the second brightness relative to the first brightness, so that the third information obtained by processing the first information based on the brightness contrast information can show not only the trend of change between the brightness of the first data and the brightness of the second data, but also the actual change of the brightness of the second data relative to the brightness of the first data, and the degree of consistency between the third information and the data display change of switching from the first data to the second data can be improved.
Based on the foregoing embodiment, the first information is processed based on the brightness contrast information to obtain the third information, which can be implemented through steps A1 to A3:
step A1, determining brightness adjustment parameters.
In one embodiment, the brightness adjustment parameter may represent a weight coefficient for adjusting the brightness contrast information; for example, the brightness adjustment parameter may vary with a usage scene of the display screen or the electronic device, and for example, the brightness adjustment parameter may have a one-to-one association relationship with the usage scene, for example, in an office scene, the brightness adjustment parameter may be a first parameter, and in a home scene, the brightness adjustment parameter may be a second parameter; for example, the brightness adjustment parameter may be related to a usage period of the display screen or the electronic device, such as when the usage period is an office period, the brightness adjustment parameter is a third parameter, and when the usage period is a rest period, the brightness adjustment parameter may be a fourth parameter.
And A2, adjusting the brightness contrast information based on the brightness adjustment parameters to obtain a brightness adjustment result.
For example, the brightness adjustment result may include a result of enhancing or deemphasizing the brightness contrast information.
For example, an adjustment algorithm may be determined, and then the brightness contrast information is adjusted based on the brightness adjustment parameter by the adjustment algorithm, so as to obtain a brightness adjustment result; for example, the adjustment algorithm may correspond to a usage period and/or a usage scenario of the display device or the electronic device, which is not limited in the embodiment of the present application.

And A3, adjusting the first information based on the brightness adjustment result to obtain third information.
For example, if the brightness adjustment result indicates that the brightness contrast information is enhanced, the first information may be enhanced based on the brightness adjustment result, so as to obtain the third information; if the brightness adjustment result indicates that the brightness contrast information is weakened, the first information is subjected to subtraction processing based on the brightness adjustment result, and third information is obtained.
As can be seen from the above, in the display control method provided in the embodiment of the present application, after the brightness adjustment parameter is determined, the brightness contrast information is adjusted based on the brightness adjustment parameter to obtain the brightness adjustment result, and then the first information is adjusted based on the brightness adjustment result to obtain the third information.
Therefore, the display control method provided by the embodiment of the application adjusts the brightness contrast information based on the brightness adjustment parameter to obtain the brightness adjustment result, so that flexible, diversified and controllable adjustment of the brightness contrast and even the first information can be realized by adjusting the brightness adjustment parameter, and when the brightness adjustment parameter is associated with the actual display requirement, targeted, flexible and self-adaptive adjustment of the brightness contrast information and even the first information can be realized by adjusting the brightness adjustment parameter, thereby improving the display effect of the display device.
Based on the foregoing embodiments, in the display control method provided in the embodiments of the present application, determining the brightness adjustment parameter may be implemented by the process shown in fig. 3, and fig. 3 is a schematic diagram of the process for determining the brightness adjustment parameter provided in the embodiments of the present application, as shown in fig. 3, the process may include steps 301 to 304:
and step 301, responding to the adjustment operation of the first information to obtain initial brightness.
In one embodiment, the adjustment operation on the first information may include an operation triggered by a user, such as a touch operation or a slide operation input by the user to the display device, an adjustment operation input by the user to a peripheral control device of the electronic apparatus; illustratively, the peripheral control devices may include a mouse or a keyboard, or the like.
In one embodiment, the adjustment operation on the first information may include an operation automatically triggered by the electronic device, for example, when a usage scene or a usage period of the electronic device or the display screen changes or an environmental state changes, the adjustment operation on the first information may be automatically triggered.
In one embodiment, the initial brightness may include an increased, decreased, or maintained brightness of the first information after quantizing the adjustment operation.
Step 302, obtaining an initial brightness adjustment parameter.
In one embodiment, the initial brightness adjustment parameter may be stored in the electronic device; for example, the initial brightness adjustment parameters may be different for different models or types of display screens; for example, the initial brightness adjustment parameter may be adjusted according to at least one of a size, a process, a material, an age, power consumption, and an operation mode of the display screen.
For example, the usage scenario and/or the usage period of the electronic device or the display screen may have a one-to-one association relationship with the initial brightness adjustment parameter, which is not limited in this embodiment of the present application.
Step 303, determining a brightness adjustment step size based on the first information and the initial brightness.
For example, the brightness adjustment step may include a brightness step in which the initial brightness is adjusted step by step; for example, the brightness adjustment step size may include at least one brightness adjustment unit; the brightness adjustment unit may include a basic unit of brightness adjustment of the electronic device.
For example, the brightness adjustment step size may be determined by:
obtaining an operation parameter for adjusting the operation from the first information to the initial brightness, and determining a brightness adjustment step length based on the operation parameter; wherein the operation parameter may include the number of times of execution of an adjustment operation from the first information adjustment to the initial brightness; for example, the brightness adjustment step size is determined based on the operation parameter, which may be a quotient of a brightness difference between the first information and the initial brightness, and the number of times of execution.
Step 304, determining a brightness adjustment parameter based on the brightness adjustment step size and the initial brightness adjustment parameter.
For example, the initial brightness adjustment parameter may be corrected based on the brightness adjustment step size, and the correction result may be determined as the brightness adjustment parameter.
As can be seen from the above, in the display control method provided in the embodiment of the present application, the initial brightness is obtained in response to the adjustment operation on the first information, and after the initial brightness adjustment parameter is obtained, the brightness adjustment parameter can be determined based on the first information and the initial brightness adjustment parameter.
Therefore, in the display control method provided by the embodiment of the application, the initial brightness obtained according to the adjustment operation on the first information is added in the process of determining the brightness adjustment parameter, so that the brightness adjustment parameter can be dynamically adjustable and controllable, and the determination mode of the brightness adjustment parameter is more flexible and controllable; the brightness adjustment parameter is determined by a brightness adjustment step length determined based on the first information and the initial brightness, and the initial brightness adjustment parameter, so that the brightness adjustment parameter adjustment process not only includes the factors of the adjustment operation, but also includes the historical brightness information of the display device, and further the brightness adjustment parameter can better conform to the actual data display state of the display device.
Based on the foregoing embodiment, in the display control method provided in the embodiment of the present application, determining the brightness adjustment step size based on the first information and the initial brightness may be implemented in the following manner:
and if the first condition or the second condition is met, determining the brightness adjustment step size as a first step size.
Wherein the first condition comprises that the first brightness is less than the second brightness and the first information is less than the initial brightness; the second condition includes the first value being greater than the second value and the first information being greater than the initial brightness.
For example, if the first condition is not satisfied and the second condition is not satisfied, it may be determined that the brightness adjustment step size is not the first step size.
Illustratively, determining the brightness adjustment step size based on the first information and the initial brightness may also be implemented by:
and if the third condition or the fourth condition is met, determining the brightness adjustment step size as a second step size.
Wherein the third condition includes the first lightness being less than the second lightness and the first information being greater than the initial brightness; the fourth condition includes the first brightness being greater than the second brightness and the first information being less than the initial brightness.
For example, if the third condition and the fourth condition are not satisfied, it may be determined that the brightness adjustment step size is not the second step size.
In one embodiment, the first information being less than the initial brightness may include the adjustment operation of the first information including an operation of increasing brightness; the adjusting operation of the first information to be greater than the initial brightness may include a brightness decreasing operation.
Illustratively, the first step size and the second step size may be different.
Exemplary, in br A <br B And the adjustment operation is a brightness increase operation, or br A >br B When the adjustment operation is a brightness reduction operation, the brightness adjustment step length, i.e., the first step length, may be δ; illustratively, the initial brightness adjustment parameter is γ 0 Under the condition that the lightness adjustment parameter is represented as γ, γ can be calculated by the general formula (6):
γ＝γ 0 +l*δ (6)
where l may be an integer greater than or equal to 1, representing the adjustment of the parameter γ to the initial brightness 0 The number of adjustments.
Illustratively, inbr A <br B And the adjustment operation is a brightness reduction operation, or br A >br B When the adjustment operation is a brightness increase operation, the brightness adjustment step length, namely the first step length, can be delta; illustratively, the initial brightness adjustment parameter is γ 0 Under the condition that the lightness adjustment parameter is represented as γ, γ can be calculated by the general formula (7):
γ＝γ 0 -l*δ (7)
for example, in the case that the first condition, the second condition, the third condition, and the fourth condition are not satisfied, the brightness adjustment step size may be determined to be 0, that is, the initial brightness adjustment parameter is determined to be the brightness adjustment parameter.
As can be seen from the above, in the display control method provided in the embodiment of the present application, if the first condition or the second condition is satisfied, the brightness adjustment step size is determined as the first step size; if the third condition or the fourth condition is met, determining the brightness adjustment step length as a second step length, wherein the first condition comprises that the first brightness is smaller than the second brightness and the first information is smaller than the initialized brightness, and the second condition comprises that the first brightness is larger than the second brightness and the first information is larger than the initial brightness; the third condition includes the first brightness being less than the second brightness and the first information being greater than the initial brightness, and the fourth condition includes the first brightness being greater than the second brightness and the first information being less than the initial brightness.
Therefore, the display control method provided by the embodiment of the application can flexibly determine the brightness adjustment step length under various different conditions according to the first brightness, the second brightness, the first information and the size relationship between the initial brightness, so that diversified brightness adjustment step lengths are obtained, and the actual display adjustment requirement of a display screen can be met; in addition, in the process of determining the brightness adjustment step length, the first brightness, the second brightness, the first information and the initial brightness are fully considered, so that the brightness adjustment step length not only contains the characteristic information of the display data, but also contains the brightness adjustment information of the display screen, and the accuracy of the brightness adjustment step length is further improved.
Based on the foregoing embodiment, in the display control method provided in the embodiment of the present application, the processing of the third information and the determination of the second information may be implemented in the following manner:
determining a luminous flux parameter; the third information is processed based on the luminous flux parameter to determine second information.
Wherein the luminous flux parameter comprises a luminous flux contrast parameter when the display device switches from displaying the first data to displaying the second data.
Luminous flux refers to the amount of derivative of radiant flux evaluated according to the standard human eye visual characteristics specified internationally, and is equal to the product of radiant energy in a certain wavelength band per unit time and the relative visibility of that wavelength band. The unit of luminous flux is lm (lumen); luminance refers to the luminous flux emitted by a light source in a unit solid angle of forward projection unit surface area on a plane perpendicular to its direction of light transmission, in candelas per square meter (cd/m) 2 ) Also known as nit; solid angle represents the angle of an object to the three-dimensional space of a particular point, and is an analogy of the plane angle in three-dimensional space.
For example, assuming that the display area of the display device is S and n pixel points are arranged in the display device, the luminous flux of the display device is equal to the sum of the luminous fluxes of the pixel points, and the luminous flux of the display device, in terms of the relationship between the luminous flux and the luminance, is equal to the sum of the luminance of each pixel point multiplied by the surface area and the solid angle, that is, as shown in equation (8):
φ＝φ 1 +φ 2 +…+φ n ＝(L 1 +L 2 +…+L n )ΩS (8)
wherein phi 1 、φ 2 …, and phi n The luminous fluxes of the first, second, … and the nth pixel point of the display device are shown; l is 1 、L 2 …, and L 2 The luminance of the first pixel point, the second pixel point, the … and the nth pixel point are respectively.
For example, the light flux parameter may include a difference between a light flux when the display device displays the first data with the first information to a light flux when the display device displays the second data with a default brightness; for example, the light flux parameter may include a ratio between a light flux when the display device displays the first data with the first information to a light flux when the display device displays the second data with a default brightness; for example, the default brightness may include a preset display brightness of the display device; illustratively, the default brightness may be different from the first information, or may be the first information.
For example, the third information may be subjected to weighting processing based on the light flux parameter, thereby determining the second information.
As can be seen from the above, in the display control method provided in the embodiment of the present application, after the luminous flux is determined, the third information can be processed based on the luminous flux parameter, so as to determine the second information; wherein the luminous flux parameter comprises a luminous flux contrast parameter when the display device switches from displaying the first data to displaying the second data.
Therefore, in the display control method provided by the embodiment of the application, when the second information is determined, the luminous flux when the display device displays the first data and the second data is taken into consideration, so that the second information not only includes static factors such as data display performance of the display device, but also includes dynamic factors when the display device displays the first data and the second data, and the display effect of the second information on the second data can be effectively improved within the performance parameter range of the display device.
Based on the foregoing embodiments, in the display control method provided in the embodiments of the present application, determining the light flux parameter may be implemented in the following manner:
acquiring a first luminous flux; determining a second luminous flux based on the first information; a luminous flux parameter is determined based on the first luminous flux and the second luminous flux.
Wherein the second luminous flux includes a luminous flux when the display device displays the second data based on the first information.
The first luminous flux may include a luminous flux when the display device displays the first data with the first information, and the first luminous flux and the second luminous flux may include a luminous flux of at least partial regions when the display device displays the first data and the second data with the first information, respectively.
In one embodiment, the luminous flux parameter may include a ratio between the first luminous flux and the second luminous flux; illustratively, the first luminous flux phi A And a second luminous flux phi B Can be calculated by equations (9) to (10), respectively:
φ A ＝φ A1 +φ A2 +…+φ An ＝(L A1 +L A2 +…+L An )ΩS (9)
φ B ＝φ B1 +φ B2 +…+φ Bn ＝(L B1 +L B2 +…+L Bn )ΩS (10)
wherein S is the area of a display screen of the display device; phi is a A1 、φ A2 …, and phi An Luminous fluxes of first, second, …, and nth pixel point for representing the first data; l is A1 、L A2 …, and L An The luminance of the first, second, … and the nth pixel point used for representing the first data; omega is a solid angle; phi is a B1 、φ B2 …, and phi Bn The luminous fluxes of the first, second, … and the nth pixel point of the second data, respectively; l is B1 、L B2 …, and L Bn The first, second, … for representing the second data, and the luminance of the nth pixel point.
For example, the luminous flux parameter may include a ratio between the first luminous flux and the second luminous flux; illustratively, according to equations (9) to (10), determining the luminous flux parameter y can be represented by equation (11):
Figure BDA0003785171110000191
for example, in order to reduce the degree of the luminance step when the display device switches from displaying the first data to displaying the second data and to make the overall luminance output of the display device as smooth as possible, and integrate the differences of luminance display corresponding to different color definitions, the color definitions may be normalized based on the first luminous flux and the target luminous flux, and the results of the normalization of the color definitions based on the first luminous flux and the target luminous flux may be the same, as shown in equation (12):
Figure BDA0003785171110000201
wherein phi is B ' is a target luminous flux when the display device displays the second data, and the target luminous flux is an unknown number related to the second luminous flux; illustratively, target luminous flux phi B ' may be obtained by assuming the target luminance β, i.e., the second information, the first information, and the second luminous flux, as shown in equation (13):
Figure BDA0003785171110000202
then, according to equation (13), equation (12) can be converted to equation (14):
Figure BDA0003785171110000203
illustratively, adding the factor of the brightness adjustment parameter γ, equation (14) may be further converted into equation (15):
Figure BDA0003785171110000204
that is to say, when the display device switches from displaying the first data to displaying the second data, the display brightness of the display device is adjusted to the second information β, so that the brightness of the ith pixel point in the second data is uniformly adjusted to the second information β on the basis of the original brightness of the second data
Figure BDA0003785171110000205
For example, when each pixel of the first data and the second data is black, the display brightness of the display device may not be adjusted, that is, the first information may be kept unchanged.
For example, for an OLED, the display brightness of each pixel point can be controlled individually; for the LCD, since the backlight brightness can be obtained, the brightness of each pixel point can be obtained based on the brightness of the filtered RGB minimum unit obtained by factory test.
In the above embodiments, the lightness of a color is also called the brightness of a color, which is one of three elements of a color, in practical applications, different colors have differences in brightness, and the same color also has variations in brightness, for example, when the lightness of display data is low, such as black and indigo, the display effect of the display device is slightly affected by properly adjusting the display brightness; when the brightness of the display content is high, such as white and yellow, the influence of turning down the display brightness on the display effect of the display device is obvious.
As can be seen from the above, in the display control method provided in the embodiment of the present application, after the first luminous flux and the second luminous flux are obtained, the luminous flux parameter can be determined based on the first luminous flux and the second luminous flux, and the first luminous flux includes a luminous flux when the display device displays the first data, and the second luminous flux includes a luminous flux when the display device displays the second data with the first information.
Therefore, according to the display control method provided by the embodiment of the application, the luminous flux parameter can reflect the luminous flux difference when the display device displays the first data and the second data, and the second luminous flux is the luminous flux when the display device displays the second data based on the first information, so that the luminous flux parameter can contain historical brightness information of the display device, and the luminous flux parameter can reflect the historical data display state of the display device more accurately.
