Detailed Description
In order to make the objects, features and advantages of the present invention more obvious and understandable, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention, and it is apparent that the described embodiments are only a part of the embodiments of the present invention, and not all of the embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present invention.
Fig. 1 is a schematic flow chart illustrating an implementation of a brightness adjustment method according to an embodiment of the present invention.
Referring to fig. 1, an aspect of the present invention provides a brightness adjustment method, including: an operation 101, receiving a mode conversion instruction for switching from a first graphics card mode to a second graphics card mode; operation 102, in response to the mode conversion instruction, acquiring the current brightness and the brightness threshold of the first graphics card mode; operation 103, performing matching processing on the current brightness and the brightness threshold of the first graphics card mode based on the first brightness matching range, and determining an expected brightness, where the expected brightness is used to represent a standard brightness corresponding to the current brightness of the first graphics card mode; operation 104, performing matching processing on the expected brightness based on the second brightness matching range, and determining the target brightness of the second graphics card mode; in operation 105, the screen brightness is adjusted to the target brightness according to the brightness adjustment rule.
The embodiment of the invention aims to provide a brightness adjusting method which is mainly applied to the technical field of computers, in particular to a dual-display-card computer and is used for ensuring that the brightness of a screen before and after mode conversion of a display card is unchanged, so that the discomfort of eyes of a user caused by the jump of the brightness after the mode conversion of the display card is avoided, and the function of protecting the vision of the user is achieved. Specifically, the brightness adjusting method provided in the embodiments of the present invention may obtain the current brightness and the brightness threshold of the first graphics card mode according to the received mode conversion instruction, match the current brightness and the brightness threshold of the first graphics card mode based on the current brightness and the brightness threshold of the first graphics card mode and the first brightness matching range, determine the expected brightness, finally match the expected brightness according to the second brightness matching range, determine the target brightness of the second graphics card mode, and adjust the screen brightness to the target brightness of the second graphics card mode according to the brightness adjusting rule.
Specifically explaining the operation process, when the brightness adjustment method provided by the embodiment of the present invention is applied to perform brightness adjustment, in operation 101, the first graphics card mode and the second graphics card mode may be any one of graphics card modes in the dual graphics card computer system, and may be determined by a graphics card that controls a display output source. The mode switching instruction is used for instructing the computer system to switch and control the display card of the display output source. Specifically, under an implementable condition, the brightness adjusting method provided by the embodiment of the invention can be applied to a dual-display-card notebook with an independent display card and an integrated display card. The display card mode can be divided into an independent display card mode and an integrated display card mode, wherein the independent display card mode can be a mode in which the independent display card controls the display output source, and the integrated display card mode can be a mode in which the integrated display card controls the display output source. Further, in the embodiment of the present invention, the first graphics card mode may be any one of an independent graphics card mode and an integrated graphics card mode, and the embodiment of the present invention does not limit the type of the first graphics card mode, and only needs to satisfy the requirement of not affecting the conversion of the graphics card mode. In addition, the second graphics card mode may be any one of an independent graphics card mode and an integrated graphics card mode, as opposed to the first graphics card mode. It should be clear that the type of the second graphics card mode may be the same as or different from the first graphics card mode, and only the mode switching of the graphics card is not affected. Therefore, the brightness adjusting method provided by the embodiment of the invention is still applicable to the situation that the first graphics card mode and the second graphics card mode are the same in type and the brands and/or performances of the graphics cards controlling the display output sources are different.
After receiving the mode conversion instruction, executing operation 102, and in response to the mode conversion instruction, obtaining the current brightness and the brightness threshold of the first graphics card mode; the current brightness of the first graphics card mode is a screen brightness value in the first graphics card mode, that is, a screen brightness value when no graphics card mode conversion is performed, and correspondingly, the brightness threshold of the first graphics card mode is a maximum screen brightness value in the first graphics card mode, it is clear that the screen brightness of the first graphics card mode and the screen brightness of the second graphics card mode can be adjusted by a Pulse Width Modulation (PWM), and the PWM values are in a proportional relationship with the adjusted screen brightness value. That is, in an implementable case, the current brightness and the brightness threshold of the first graphics card mode may be represented by corresponding PWM values, and thus, the obtaining of the current brightness and the brightness threshold of the first graphics card mode in operation 102 is to obtain the PWM value corresponding to the current brightness and the PWM value corresponding to the brightness threshold, respectively.
In operation 103, a current luminance of the first graphics card mode and a luminance threshold are matched based on the first luminance matching range, and an expected luminance is determined, where the expected luminance is used to represent a standard luminance corresponding to the current luminance of the first graphics card mode. The standard luminance is a measure of the brightness of the light emitting surface, and is a ratio of the light emission intensity of the light emitting surface in a predetermined direction to the area of the light emitting surface perpendicular to and in the predetermined direction. Correspondingly, the first brightness matching range may be a comparison table of the current brightness and the brightness threshold of the first graphics card mode and the standard brightness, and the first brightness matching range is determined by the graphics card corresponding to the first graphics card mode. Specifically, when the first graphics card mode is the integrated graphics card mode, the first brightness matching range is a comparison table of the current brightness and the brightness threshold of the integrated graphics card mode and the standard brightness. In an implementation case, the first brightness matching range may be information of a comparison relationship between PWM values corresponding to the current brightness and the brightness threshold respectively in the first graphics card mode and the standard brightness, and is used to determine the expected brightness according to the PWM value corresponding to the current brightness and the PWM value corresponding to the brightness threshold in the first graphics card mode. The expected brightness is one of the standard brightness in the first brightness matching range, and the expected brightness can be used for representing the standard brightness corresponding to the current brightness of the first graphics card mode. It should be clear that the expected brightness may be obtained by matching the PWM value corresponding to the current brightness in the first brightness matching range, or may be obtained by matching the PWM value corresponding to the current brightness and the PWM value corresponding to the brightness threshold in the first brightness matching range after being preprocessed. And the expected brightness may be used to indicate or determine a target brightness for the second graphics card mode.
Fig. 2 is a schematic diagram illustrating a process of determining an expected brightness of a brightness adjustment method according to an embodiment of the present invention.
Referring to fig. 2, in an implementation, the matching, in operation 103, the current luminance of the first graphics card mode and the luminance threshold based on the first luminance matching range to determine the expected luminance includes: operation 1031, integrating the current brightness and the brightness threshold of the first graphics card mode to obtain a first integration coefficient; in operation 1032, the first integration coefficient is matched based on the first luminance matching range to obtain the desired luminance.
Specifically, in order to obtain the expected brightness for indicating or determining the target brightness, in operation 1031, the current brightness and the brightness threshold of the first graphics card mode are integrated to obtain a first integration coefficient. In one implementation case, the first graphics card mode may be an integrated graphics card mode. The integration of the current brightness and the brightness threshold of the first graphics card mode may obtain a first integration coefficient, where the integration operation may be to obtain a ratio of the current brightness and the brightness threshold of the first graphics card mode, and at this time, the first integration coefficient is a ratio of a PWM value corresponding to the current brightness and a PWM value corresponding to the brightness threshold. Then, in operation 1032, matching is performed in the first luminance matching range according to the first integration coefficient, and a desired luminance is obtained. In an implementation case, the first luminance matching range may be a comparison table of the first integration coefficient of the first graphics card mode and the standard luminance, which may include a comparison relationship between the first integration coefficient and the standard luminance, and the expected luminance may be finally determined by performing matching in the first luminance matching range according to the first integration coefficient. Wherein the expected brightness is one of the standard brightness in the first brightness matching range.
After determining the expected brightness, in order to determine the target brightness of the second graphics card mode, in operation 104, the expected brightness is matched based on the second brightness matching range, and the target brightness of the second graphics card mode is determined. The second brightness matching range may be a comparison table of standard brightness and target brightness of the second graphics card mode. Specifically, the second brightness matching range may be a comparison table of the standard brightness and the PWM value corresponding to the target brightness in the second graphics card mode, and it is to be understood that the expected brightness is one of the standard brightness in the second brightness matching range, so that the second brightness matching range may be used to determine the PWM value corresponding to the target brightness in the second graphics card mode, that is, the target brightness in the second graphics card mode, based on the expected brightness. It should be clear that the standard brightness corresponding to the target brightness of the second graphics card mode should be consistent with the expected brightness.
Fig. 3 is a schematic diagram illustrating a target brightness determination process of a brightness adjustment method according to an embodiment of the present invention.
Referring to fig. 3, in an implementation, the operation 104, performing matching processing on the expected luminance based on the second luminance matching range to determine the target luminance of the second graphics card mode, includes: operation 1041, matching the expected brightness based on the second brightness matching range to obtain a second integration coefficient; in operation 1042, the target brightness of the second video card mode is determined according to the second integration coefficient.
Specifically, in operation 1041, in order to determine the target brightness of the second graphics card mode, the expected brightness is matched based on the second brightness matching range, and a second integration coefficient is obtained. In one implementation, the expected brightness may be determined by a first brightness matching range matching a current brightness of the first graphics card mode to a brightness threshold. The second luminance matching range may be a comparison table of the standard luminance and the second integration coefficient, which may include a comparison relationship of the standard luminance and the second integration coefficient. Further, the expected luminance may be one of the standard luminances in the second luminance matching range, and therefore, the second integration coefficient may be determined based on the expected luminance that can be matched in the second luminance matching range. The type of the second integration coefficient is not limited herein, but it is to be understood that the second integration coefficient has a contrast relationship with the target brightness of the second graphics card mode, and therefore, the operation 1042 may determine the target brightness of the second graphics card mode according to the second integration coefficient. In one implementation case, the second integration coefficient is the same kind as the first integration coefficient, and is a ratio of two PWM values.
Finally, operation 105 is performed to adjust the screen brightness to the target brightness according to the brightness adjustment rule. The brightness regulation rule is a rule for controlling the brightness regulation method, and it is clear that the brightness regulation method regulated by the rule precedes the brightness regulation rule itself, and the function of the rule is to control, change or unify the mode of the brightness regulation method.
In one embodiment, the brightness adjustment rule includes at least one of the following rules: a first brightness adjustment rule corresponding to the startup brightness; and a second brightness adjustment rule corresponding to the brightness gradual change mode.
The first brightness adjustment rule corresponding to the startup brightness is a brightness adjustment rule for adjusting the startup brightness, and can be applied to the conditions of startup, sleep termination and dormancy of a computer system. Specifically, when the computer is power-on self-test, the brightness value stored in the computer system may be the brightness information before the previous system shutdown. Further, the graphics card mode before the previous system shutdown is the integrated graphics card mode, and the integrated graphics card mode before the previous shutdown is determined as the first graphics card mode, so that the brightness setting may include current brightness information and brightness threshold information of the first graphics card mode. Further, the screen brightness is adjusted to a brightness threshold value by pulse width modulation according to the brightness threshold value information to indicate that the user computer is being powered on. After the computer system is started, in order to ensure that the brightness of the screen after the computer system is started is consistent with the brightness before the computer system is shut down for the previous time, the brightness of the screen is adjusted by pulse width modulation according to the current brightness information of the first display card mode.
Further, the second brightness adjustment rule corresponding to the brightness gradual change mode is a brightness adjustment rule for smoothly adjusting brightness, and can be applied to the situation of screen brightness jump, for example, when a user manually adjusts the screen brightness, the second brightness adjustment rule plays a role in smoothly adjusting the brightness. In an implementable situation, the second brightness adjustment rule provided in the embodiment of the present invention may be further applied to a process of adjusting the screen brightness according to the current brightness information of the first graphics card mode when the computer system is started. Specifically, after the computer system is started, in order to ensure that the brightness of the screen after the computer system is started is consistent with the brightness before the computer system is started, the brightness of the screen needs to be adjusted according to the current brightness information of the first graphics card mode, wherein the brightness of the screen after the computer system is started can be represented by a PWM value corresponding to a brightness threshold, correspondingly, the current brightness of the first graphics card mode can be represented by the PWM value corresponding to the current brightness, and in addition, the graphics card mode after the computer system is started is consistent with the graphics card mode before the computer system is stopped, so that a brightness difference value can be determined according to the PWM value corresponding to the brightness threshold and the PWM value corresponding to the current brightness, and is used for representing the difference between the PWM value corresponding to the brightness threshold and the PWM value corresponding to the current brightness. And finally, adjusting the brightness based on the equally divided brightness difference, thereby achieving the effect of smoothly adjusting the brightness when the brightness jumps. In addition, under another implementation condition, whether the user applies the shortcut key to adjust the brightness or not can be detected, when the condition that the user applies the shortcut key to adjust the brightness is detected, the brightness difference is obtained according to the brightness adjusting information of the user, and then the brightness can be adjusted based on the second brightness adjusting rule, so that the brightness can be smoothly adjusted.
In order to facilitate further understanding of the implementation method, a specific implementation scenario is provided below, where the brightness adjustment method provided in the embodiment of the present invention can keep the screen brightness unchanged before and after the mode switching of the graphics card, and has an effect of protecting the eyesight of the user. Specifically, in an implementation scenario of the embodiment of the present invention, the first graphics card mode is a mode in which the integrated graphics card controls the display output source, the second graphics card mode may be a mode in which the independent graphics card controls the display output source, and the current brightness of the first graphics card mode is a screen brightness value in the first graphics card mode, that is, a screen brightness value when the graphics card mode is not converted. Correspondingly, the brightness threshold of the first graphics card mode is the maximum screen brightness value in the first graphics card mode, in addition, the first brightness matching range may be a comparison table of the current brightness and the brightness threshold of the first graphics card mode and the standard brightness, and the second brightness matching range may be a comparison table of the standard brightness and the target brightness of the second graphics card mode. When the brightness adjusting method provided by the embodiment of the invention is applied, the PWM value corresponding to the current brightness of the first graphics card mode and the PWM value corresponding to the brightness threshold can be obtained according to the obtained mode conversion instruction, based on the PWM value corresponding to the current brightness of the first graphics card mode and the PWM value corresponding to the brightness threshold, matching the current brightness and the brightness threshold value of the first display card mode with a reference table of standard brightness to determine the standard brightness of the current screen, wherein the standard brightness is the expected brightness, which is used for indicating or determining the target brightness of the second graphics card mode, specifically, matching in the second brightness matching range according to the expected brightness in the standard brightness, determining the target brightness of the second graphics card mode, and finally, adjusting the screen brightness to the target brightness of the second video card mode based on the brightness adjusting rule according to the PWM value corresponding to the expected brightness in the second video card mode.
Fig. 4 is a schematic diagram of a luminance range obtaining process of a luminance adjusting method according to an embodiment of the present invention.
Referring to fig. 4, in an embodiment, the method further comprises: operation 401, detecting whether a dynamic display card switching mode is supported; in operation 402, when it is detected that the mode of dynamically switching the graphics card is supported, a first luminance matching range and a second luminance matching range are obtained.
In an implementation manner, before receiving a mode switching instruction for switching from the first graphics card mode to the second graphics card mode in operation 101, the method for adjusting brightness according to an embodiment of the present invention may further include operation 401 of detecting whether a dynamic switching graphics card mode is supported. The dynamic display card switching mode is a mode which can meet the requirement that an independent display card mode and an integrated display card mode are freely switched in a starting state, and is a mode which can exert the performance of a computer to a great extent. When the dynamic switching of the graphics card mode is detected, a first brightness matching range and a second brightness matching range are obtained according to operation 402. In an implementation case, the first brightness matching range may be a comparison table of the current brightness and the brightness threshold of the first display card mode and the standard brightness, and is determined by the first display card controlling the display output source. Correspondingly, the second brightness matching range may be a comparison table of the standard brightness and the target brightness of the second display card mode, and is determined by the second display card controlling the display output source. Further, the first luminance matching range and the second luminance matching range can be obtained by networking and downloading after being determined according to the display card, and can also be obtained after reading a bottom layer program of the display card.
In a specific implementation situation, an embodiment of the present invention provides a brightness adjustment method, which has an effect of keeping screen brightness unchanged before and after mode switching of a graphics card, and prevents discomfort of eyes of a user caused by screen brightness jump after switching of a display output source of the graphics card, thereby achieving an effect of protecting eyesight of the user. In an implementation situation, the brightness adjusting method provided in the embodiment of the present invention can be applied to a chip for adjusting the screen brightness of a dual-display-card computer. Specifically, in the embodiment of the present invention, the first graphics card mode is a mode in which the integrated graphics card controls the display output source, that is, an integrated graphics card mode. The second video card mode may be a mode in which the independent video card controls the display output source, i.e., an independent video card mode. The current brightness of the first graphics card mode is a screen brightness value in the first graphics card mode, that is, a screen brightness value when the graphics card mode conversion is not performed. Correspondingly, the brightness threshold of the first graphics card mode is the maximum screen brightness value in the first graphics card mode, in addition, the first brightness matching range may be a comparison table of the current brightness and the brightness threshold of the first graphics card mode and the standard brightness, and the second brightness matching range may be a comparison table of the standard brightness and the target brightness of the second graphics card mode.
Further, when the embodiment of the invention is applied, whether the dual-display-card computer supports the dynamic switching of the display card mode is detected, and when the dual-display-card computer supports the dynamic switching of the display card mode, the first brightness matching range and the second brightness matching range are determined to be obtained. Then, after receiving a mode conversion command for switching the integrated display card mode into the independent display card mode, acquiring a PWM value corresponding to the current brightness of the integrated graphics card mode and a PWM value corresponding to a brightness threshold according to the acquired mode conversion instruction, based on the PWM value corresponding to the current brightness of the integrated graphics card mode and the PWM value corresponding to the brightness threshold, matching the current brightness and the brightness threshold value of the integrated display card mode with a comparison table of standard brightness to determine the standard brightness of the current screen, wherein the standard brightness is the expected brightness, which is used for indicating or determining the target brightness of the independent graphics card mode, specifically, matching in the second brightness matching range according to the expected brightness in the standard brightness, determining the target brightness of the independent graphics card mode, and finally, adjusting the screen brightness to the target brightness of the independent display card mode based on the brightness adjusting rule according to the PWM value corresponding to the expected brightness in the independent display card mode. The brightness adjustment rule is a rule for controlling a brightness adjustment method, and the brightness adjustment method adjusted by the rule precedes the brightness adjustment rule. In one implementation, the brightness adjustment rule includes a first brightness adjustment rule corresponding to the starting brightness and a second brightness adjustment rule corresponding to the brightness gradual change mode. In addition, after the screen brightness is adjusted to the target brightness of the independent display card mode based on the brightness adjusting rule, the brightness progress bar can be synchronously adjusted according to the target brightness, and therefore the situation that the brightness is not matched or the difference is too large and inconsistent when the user uses the progress bar for adjustment due to the fact that the brightness progress bar is not matched with the brightness progress bar under the system is avoided.
