Detailed Description
The technical solutions in the embodiments of the present application will be described clearly and completely with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are only a part of the embodiments of the present application, 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 application.
Based on the above problems, embodiments of the present application provide a brightness adjustment method, device, computer-readable storage medium, and terminal, which can effectively improve brightness adjustment efficiency. The following are detailed below. It should be noted that the following description of the embodiments is not intended to limit the preferred order of the embodiments.
Referring to fig. 1, fig. 1 is a schematic flow chart of a brightness adjusting method according to an embodiment of the present disclosure. The brightness adjustment method may be applied to mobile terminals such as mobile phones, tablet computers, notebook computers, palm computers, Portable Media Players (PMPs), and fixed terminals such as desktop computers. The specific flow of the brightness adjusting method can be as follows:
101. and acquiring the screen brightness of the current equipment.
Specifically, the screen brightness of the current device may be obtained by reading from a driver for controlling the screen brightness, where the screen brightness may refer to a brightness value of a screen surface when the terminal device displays the same screen. For example, the luminance value may be 1cd/m2(candelas per square meter), etc.
In some embodiments, after the screen brightness is obtained, in order to quickly adjust the screen brightness, the brightness adjustment information may be stored in the terminal memory in advance, that is, before the step "obtaining the screen brightness of the current device", the following process may be further included:
determining the brightness information base according to a preset brightness range;
converting the information in the brightness information base into data in a specified format;
and burning the data into the memory.
The preset luminance range may be set according to actual conditions, and may be set to various luminance ranges, for example, the preset luminance range may be 0 to 10cd/m2And the like. The brightness information base may be a brightness information table. Specifically, after the preset brightness range is determined, the brightness information table is established according to the preset brightness range. The brightness adjustment information of each brightness within the preset brightness range may be recorded in the brightness information table.
Specifically, the luminance information table may include luminance levels and input luminance and output luminance corresponding to each luminance level. The brightness level can be determined by a preset brightness range, for example, the preset brightness range can be 0-10 cd/m2The preset luminance range can be divided into 10 luminance levels, wherein the luminance value is 0-1 cd/m2The level can be set to 1 st level, and the brightness value is 2-3 cd/m2A level of 2 may be set, and so on.
The input brightness may represent a gamma (gray scale) value of each area of the screen display area at the current screen brightness. The gray scale is a change in luminance between the brightest and darkest, and is divided into a plurality of parts. So as to control the screen brightness corresponding to the signal input. Each digital image is composed of a plurality of dots, also called pixels (pixels), each of which can usually represent a plurality of different colors, and is composed of three sub-pixels of red, green and blue (RGB). Each sub-pixel, the light source behind it, may exhibit a different brightness level. And the gray levels represent gradation levels of different brightness from the darkest to the brightest. The more the intermediate levels are, the more exquisite the picture effect can be presented.
The output brightness may represent a corresponding brightness adjustment parameter determined according to a gamma value of a screen display area when the terminal screen is at a certain brightness level. The terminal can adjust the display brightness of the terminal device through the output brightness.
Specifically, after determining the brightness information table, the brightness information table is converted into a data format, where the data format may include multiple formats, for example, the data format may be a binary format, and the like. Further, all data representing the luminance information table may be saved in a folder, which is stored in a recordable format, for example, the recordable file format may be a bin (binary) file format.
Specifically, data is burned into the memory. The brightness information data file can be burned into the screen driving chip in an OTP (One-time Password) manner. The burning method may include a plurality of ways, for example, manual burning may be performed by connecting a burner, or online burning may be performed by using a program code.
In some embodiments, the step of "burning data into a memory" may include the following steps:
determining a register to be read and written from a screen driving chip of the equipment;
and writing the data into the register to be read and written.
Specifically, the register to be read and written is determined from a screen driving chip of the device. A set of readable and writable registers can be searched from all registers by reading all registers on a terminal screen driving chip. Among them, a register is a very important kind of memory cell in an integrated circuit, and is usually composed of flip-flops. In integrated circuit design, registers can be divided into two categories, registers used inside the circuit and registers that serve as internal and external interfaces.
After the readable and writable register is determined, the brightness information data is written into the register in a burning mode. The brightness adjustment of the screen is realized by burning brightness adjustment parameters on the display driving chip in a hardware mode, so that the image quality damage caused by a software scheme can be avoided.
102. Matching the screen brightness with a preset brightness range, judging whether the screen brightness accords with the preset brightness range, and if so, executing the step 104; if not, go to step 103.
In some embodiments, specifically, matching the screen brightness with the preset brightness range may have an error in the matching, for example, the brightness value may be a small value, and when the brightness value is a small value, the matching result may be inaccurate. In order to improve the matching accuracy, the brightness may be graded and the matching of the brightness level may be performed. That is, the step of "matching the screen brightness with the preset brightness range" includes the following steps:
determining the screen brightness level corresponding to the screen brightness;
determining a brightness level based on a preset brightness range;
and matching the screen brightness level with the brightness level.
Specifically, the screen brightness level corresponding to the screen brightness is determined. After the terminal acquires the screen brightness, the screen brightness level can be determined according to the acquired screen brightness. Among them, there are various ways of dividing the brightness levels. For example, the maximum brightness and the minimum brightness of the screen may be obtained according to the actual situation, that is, the maximum brightness and the minimum brightness of the terminal screen are obtained, the brightness is determined to be divided into a plurality of levels, and different brightness levels are corresponded to different brightness levels.
For example, the maximum luminance of the terminal may be 100cd/m2The minimum luminance may be 0cd/m2The brightness level of the terminal may be divided into 10 levels, that is, may be divided into: the 1 st level corresponds to a luminance of 0 to 10cd/m2The 2 nd level brightness may be 10-20 cd/m2(excluding 10 cd/m)2) The 3 rd level brightness may be 20-30 cd/m2(excluding 20 cd/m)2) And (5) equalizing the brightness division mode. If the acquired screen brightness can be 10cd/m2Then the corresponding screen brightness level may be level 1.
Specifically, the brightness level is determined based on a preset brightness range, where the preset brightness range may refer to that when the screen brightness is in the brightness interval, the current dimming mode of the terminal may be switched. For example, the predetermined brightness range may be 0 to 30cd/m2The corresponding brightness levels may be level 1, level 2, level 3.
After determining the screen brightness level and the brightness level, the screen brightness level and the brightness level are matched. For example, the screen brightness level may be level 1, and the brightness level may be level 1, level 2, or level 3, and if the screen brightness level and the brightness level are successfully matched according to the matching result, step 104 may be performed.
For another example, if the screen brightness level may be level 4, and the brightness level may be level 1, level 2, or level 3, and the screen brightness level and the brightness level fail to be matched according to the matching result, step 103 may be executed.
103. And finishing the operation.
When the screen brightness fails to match the preset brightness range, the terminal may stop the related operations, and maintain the initial dimming mode to adjust the screen brightness, for example, the initial dimming mode may be DC dimming, etc.
104. If yes, determining brightness adjusting information of the screen brightness from a brightness information base, wherein the brightness information base comprises all brightness adjusting information in a preset brightness range.
Specifically, when it is detected that the screen brightness is within the preset brightness range, the brightness adjustment information of the screen brightness can be searched from the brightness information base. The brightness adjustment information may be a brightness adjustment parameter. For example, the brightness adjustment parameter may be an input brightness gray scale value and an output brightness gray scale value.
Specifically, after the screen brightness level is determined according to the screen brightness, the input gray level value and the output gray level value corresponding to the screen brightness level can be searched according to the brightness information table. For example, the screen brightness level may be level 1, and the brightness adjustment information with the brightness level of level 1 found according to the brightness information table may be: the input brightness is 0 and the output brightness is 0; the input brightness is 1, and the output brightness is 1; input luminance is 2, output luminance is 2, and so on.
105. And adjusting the display brightness of the equipment based on the brightness adjusting information, wherein the display brightness is the brightness of a content display area in the equipment.
Specifically, the display brightness of the device is adjusted based on the brightness adjustment information. The display brightness can refer to different brightness of different areas when the same picture is displayed on the terminal, and the effect of the same brightness of the terminal screen can be achieved by changing the gray scale of the display content.
In some embodiments, the step "adjusting the display brightness of the device based on the brightness adjustment information" may include the following processes:
acquiring a brightness value of display brightness;
determining brightness adjusting parameters corresponding to the brightness values based on the brightness adjusting information;
and adjusting the display brightness to the target brightness according to the brightness adjusting parameter.
Specifically, the brightness value of the display brightness is obtained, where the display brightness may include multiple brightnesses, and the terminal screen may present different brightnesses in different areas when displaying the same picture. The brightness value may be the brightness value of any content in the current terminal screen display area, and the brightness value may be represented as a gray-scale value. For example, the brightness value may be the brightest area in the current screen display area, and the gray scale value of the brightest area may be 3.
After the brightness value is determined, the terminal can search the brightness adjusting parameter corresponding to the brightness value according to the data in the brightness information base. The brightness value can be modified according to the brightness adjusting parameter, so that the brightness of the display area where the brightness value is grown is adjusted to the target brightness.
For example, the brightness level may be level 1, the brightness value, that is, the input brightness may be 1, it may be determined that the adjustment parameter of the brightness value, that is, the output brightness value is 1, and the terminal may modify the brightness value to 1, that is, may adjust the brightness of the area where the brightness value is located in the screen to the brightness corresponding to the brightness level of the screen.
The method comprises the steps of obtaining the screen brightness of the current equipment, matching the screen brightness with a preset brightness range, judging whether the screen brightness accords with the preset brightness range, if so, determining the brightness adjusting information of the screen brightness from a brightness information base, wherein the brightness information base comprises adjusting information of all brightness in the preset brightness range, adjusting the display brightness of the equipment based on the brightness adjusting information, and the display brightness is the brightness of a content display area in the equipment. According to the scheme, the brightness information data is burnt on the display driving chip, low-brightness DC dimming of the display device is achieved based on a hardware mode, damage to image display quality is avoided, and brightness adjusting efficiency can be effectively improved.
Referring to fig. 2, fig. 2 is a flowchart illustrating a second brightness adjustment method according to an embodiment of the present disclosure. In this embodiment, the specific scene application of the brightness adjustment method may be as follows:
201. and the terminal burns the brightness information base into the screen driving chip.
In this embodiment, the terminal records the luminance information base into the screen driving chip, wherein the terminal may obtain the luminance information base before recording. Specifically, the brightness information base can be formulated by the user according to actual conditions.
The terminal Display screen may include various types, such as an LCD (Liquid Crystal Display), an OLED (Organic Light-Emitting Diode), an AMOLED (Active-matrix Organic Light-Emitting Diode), and the like.
Specifically, the brightness adjustment manner of the terminal screen may include various manners, such as a DC dimming manner (a technique of adjusting brightness by directly controlling the magnitude of current on both sides of the light emitting assembly), a PWM dimming manner (a technique of changing the brightness of the screen by changing the duty ratio by controlling the length of the power-on time, and controlling the brightness by rapidly switching on and off the light source of the screen), and the like.
In this embodiment, the screen type of the terminal may be AMOLED, and the dimming mode may be a DC dimming mode or a PWM dimming mode.
Specifically, the brightness information base may be set according to a preset brightness range. Wherein. The preset brightness range can be a low brightness range displayed by the terminal screen, and the maximum brightness value in the brightness range can be a dimming switching threshold, that is, when the maximum brightness value is greater than the dimming switching threshold, the terminal screen can perform a DC dimming mode; when the maximum brightness value is less than or equal to the dimming switching threshold value, the terminal screen can switch the current dimming mode and the like.
The brightness information base is burned into the screen driving chip, and various burning modes can be provided. For example, first, the terminal may obtain all read-write registers in the display driver chip, and may determine a set of readable-writable memories from all the read-write registers, where no data is stored in the readable-writable memories. After the readable and writable register is determined, the terminal can convert the brightness information base into a binary data format and then store all data as a file, wherein the file format can be a bin file format. The programmed bin file (including all luminance data) can be burned into the set of readable and writable registers by OTP.
202. The terminal detects the brightness level of the current screen and judges whether the brightness level is less than a preset level, if so, step 203 is executed; if not, go to step 204.
Specifically, the terminal may obtain the current screen brightness by reading the brightness register data in the screen driving memory to detect the brightness level of the current screen. The terminal may determine the corresponding screen brightness level according to the screen brightness, and the specific manner may be seen in the above embodiments, which is not described herein.
After the terminal determines the screen brightness level, the screen brightness level is compared with a preset level, wherein the preset level can be set according to the adjustable maximum brightness and the adjustable minimum brightness of the screen.
For example, if the terminal screen brightness level may be 63, the preset level may be 64, and the screen brightness level is less than the preset level, step 203 may be performed.
For another example, the terminal screen brightness level may be 65 levels, the preset level may be 64 levels, and if the screen brightness level is greater than the preset level, step 204 may be executed.
203. And the terminal determines corresponding brightness adjusting information in the brightness information base according to the brightness grade.
Specifically, the terminal determines corresponding brightness adjustment information in the brightness information base according to the brightness level. Referring to fig. 6, the table in fig. 6 may be a brightness level and a brightness adjustment parameter corresponding to the brightness level. Fig. 6 includes luminance levels and input luminance and output luminance corresponding to each luminance level. The brightness level A can be determined by a preset brightness range, for example, the preset brightness range can be 0-10 cd/m2The preset luminance range can be divided into 10 luminance levels, wherein the luminance value is 0-1 cd/m2The level can be set to 1 st level, and the brightness value is 2-3 cd/m2A level of 2 may be set, and so on.
Referring to fig. 6, the input luminance C may represent a gamma value of each region of the screen display region at the current screen luminance. The output brightness B may represent a corresponding brightness adjustment parameter determined according to a gamma value of a screen display area when the terminal screen is at a certain brightness level. The terminal can adjust the display brightness of the terminal device through the output brightness. The brightness information table shown in fig. 6 can be set according to actual conditions, and the brightness of the screen display can be quickly adjusted through the brightness information table.
The terminal may formulate a brightness adjustment curve according to the brightness level and the adjustment parameter corresponding to the brightness level, see fig. 7, and fig. 7 is a schematic diagram of the brightness adjustment curve of the brightness adjustment method provided in the embodiment of the present application.
For example, the brightness adjustment curve a shown in fig. 7 may be a brightness adjustment parameter curve of any brightness within a preset brightness range, wherein the abscissa of the graph may represent the input brightness value and the ordinate may represent the output brightness value. The graph may be established according to the correspondence relationship of each brightness adjustment parameter in the brightness information base shown in fig. 6.
As the brightness adjustment curve a shown in fig. 7, the conclusion of brightness adjustment can be obtained: the screen brightness of the same level is higher when the input brightness is higher, the output brightness is also higher, and the brightness adjustment is in an ascending trend along with the increase of the input brightness. By setting the coordinate graph, the terminal can quickly acquire brightness adjustment parameter information corresponding to each brightness level so as to adjust different input brightness values of each brightness level.
204. And finishing the operation.
Specifically, when the screen brightness level may be greater than or equal to the preset level, that is, the screen brightness does not fall within the preset brightness range, at this time, the terminal may not perform related operation any more. The terminal may maintain an initial dimming mode to adjust the screen brightness, for example, the initial dimming mode may be DC dimming or the like.
205. And the terminal adjusts the display brightness of the current screen according to the brightness adjusting information.
Specifically, the terminal may adjust the display brightness of the current screen according to the brightness adjustment information in various manners. For example, the terminal may obtain the brightness adjustment parameter according to the brightness adjustment information, where the brightness adjustment parameter may be a target brightness value, and the input brightness value may be modified to the target brightness value, so as to complete brightness adjustment. For example, the input brightness value may be 1, and the brightness adjustment parameter may be 3, and the terminal may modify the input brightness value from 1 to 3, so as to complete the brightness adjustment.
For another example, the brightness adjustment parameter may be a brightness difference, and the brightness value may be calculated by the brightness difference to obtain a target brightness value, where the calculation between the brightness value and the brightness difference may be an addition calculation, for example, the input brightness value may be 1, and the brightness adjustment parameter may be 3, and then the terminal may modify the input brightness value from 1 to 4, so as to complete the brightness adjustment.
The method comprises the steps of obtaining the screen brightness of the current equipment, matching the screen brightness with a preset brightness range, judging whether the screen brightness accords with the preset brightness range, if so, determining the brightness adjusting information of the screen brightness from a brightness information base, wherein the brightness information base comprises adjusting information of all brightness in the preset brightness range, adjusting the display brightness of the equipment based on the brightness adjusting information, and the display brightness is the brightness of a content display area in the equipment.
