Based on the above problems, embodiments of the present application provide a method, an apparatus, a storage medium, and a terminal for processing file display, which can effectively reduce power consumption of the terminal. 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 flowchart illustrating a file display processing method according to an embodiment of the present disclosure. The file display processing method can be applied to mobile terminals such as terminals, tablet computers, notebook computers, palm computers, Portable Media Players (PMPs), and fixed terminals such as desktop computers. The processing method of the document display is to adjust the brightness of the display screen locally, so the display screen can be a Light-Emitting Diode (LED) display screen. The specific flow of the processing method for file display may be as follows:
101. and when the file is detected to be displayed, acquiring a display picture of the current display screen.
Specifically, the file display instruction can be triggered through touch operation of a user, and the file selected by the user is displayed on the current display screen according to the file display instruction, so that the file display can be detected. The format of the file may be various, for example, the file may be a picture, a video, a document, and so on.
When the display screen is detected to display the file, a display picture of the current display screen can be acquired, and the current display picture can be represented as an image. For example, the display file may be a picture, and the display picture acquired by the current display screen may be a picture image; or the display file may be a video, the display picture acquired to the current display screen may be a certain frame of video image of the video, and so on.
102. And determining a plurality of areas to be processed according to the display picture.
Specifically, after the display screen is acquired, a plurality of regions to be processed may be obtained according to the display screen. The to-be-processed area may be a partial area of the display screen, and the to-be-processed area may be divided for the display screen according to different characteristics, for example, the characteristics may be a content type of the display screen, a content location of the display screen, and the like.
In some embodiments, the step of "determining a plurality of regions to be processed according to the display screen" may include the following processes:
acquiring the display content of the display picture;
and dividing the display picture according to the type of the display content to obtain a plurality of regions to be processed.
Specifically, the display content of the display screen is obtained, and the display content may include multiple types, for example, the type of the display content may be characters, patterns, colors, and the like. When the display screen is divided into regions, the display screen may be divided according to the type of the display content.
For example, the current display screen may be divided according to the type of the characters, that is, the area containing the characters is divided into a plurality of areas according to different display positions of the characters, and the area not containing the characters is divided into one area, that is, a plurality of areas to be processed may be obtained; or, the current display picture can be divided according to the pattern types, and different patterns displayed by the display picture are divided into a plurality of display areas to be processed; or the current display picture can be divided according to the color types, and the areas with different colors are divided into a plurality of areas to be processed.
103. And acquiring image display information of the area to be processed.
Specifically, display information of the image to be processed is obtained, and the display information may include definition. The definition refers to the definition of an image macroscopically seen by human eyes, and is the subjective feeling of people on a final image caused by the comprehensive result of the objective performance of a system and equipment, the subjective feeling of the definition can be quantitatively tested, namely the subjective feeling can be measured by the thickness of lines between black and white, and the definition is measured by a standard test method and a standard test chart, and the measured data of the definition has a definite unit, namely a television Line (TV Line).
In the display picture of the current display screen, the definition can be determined by the number of pixel points in the current display picture and the gray value of each pixel point. Refers to the color depth of points in a black and white image, generally ranging from 0 to 255, 255 for white and 0 for black. For black and white images, the R, G, B values are all equal, called gray scale values, and each pixel has a gray scale value, and for 8-bit gray scale images, the gray scale value ranges from 0 to 255. The color or gray level refers to the difference between brightness and darkness of pixels displayed in a black-and-white display, and is expressed as the difference between colors in a color display, and the more gray levels, the clearer and more vivid the image gradation. The grey scale level depends on the number of bits of the refreshed memory cells per pixel and the performance of the display itself.
Specifically, the image display information of the region to be processed is obtained, and the definition of the region to be processed may be represented by obtaining the number of the pixels in the region to be processed and the gray value of the pixels, for example, the pixel in the region to be processed may be 1 ten thousand pixels (pixels), and the gray value of the pixel may be 100.
104. A target processing region is determined from the plurality of regions to be processed based on the image display information.
Specifically, the target processing region is determined from the plurality of regions to be processed based on the image display information, and the region to be processed may be determined from the plurality of regions to be processed according to the obtained definition of each region to be processed.
In some embodiments, the step of "determining a target processing region from a plurality of regions to be processed based on the image display information" may include the following flow:
comparing the display definition of the area to be processed with a preset display definition;
and if the display definition is smaller than the preset display definition, taking the to-be-processed area corresponding to the display definition as a target processing area.
Specifically, the display definition of the region to be processed is compared with a preset display definition, and the preset display definition can be the optimal display definition of the current display picture.
And comparing the display definition value of each to-be-processed area with a preset definition value, and if the display definition value is smaller than the preset definition value, determining the to-be-processed area corresponding to the display definition value smaller than the preset definition value as a target processing area. The target processing area is an area which needs to be subjected to definition processing.
For example, the region to be processed may include a region 1, a region 2, a region 3, a region 4, and the like, the sharpness value may be represented by the number of pixels and the gray level value of the pixels, the pixel in the region 1 may be 2 ten thousand pixels, the gray level value of the pixels may be 200, the pixel in the region 2 may be 2 ten thousand pixels, the gray level value of the pixels may be 150, the pixel in the region 3 may be 3 ten thousand pixels, the gray level value of the pixels may be 200, the pixel in the region 4 may be 1 ten thousand pixels, the gray level value of the pixels may be 100, the preset sharpness may represent that the pixels are 2 ten thousand pixels, and the gray level value of the pixels may be 200, and then the region 2 may be determined by comparing the sharpness of the region to be processed with the preset sharpness, and the region 4 may be the target. The target processing area can be quickly determined by acquiring the display information, i.e. the definition, of each to-be-processed area.
In some embodiments, when the display definition of the to-be-processed area is greater than or equal to the preset display definition, in order to reduce the power consumption of the terminal, the definition processing may not be performed on the to-be-processed area. The following steps may also be included:
and if the display definition is greater than or equal to the preset display definition, keeping the current display brightness to display the to-be-processed area.
Specifically, when the display definition of the display area is obtained to be greater than or equal to the preset definition, that is, the pixel value of the to-be-processed area and the pixel gray value of the to-be-processed area are greater than or equal to the preset pixel value and the pixel gray value, the to-be-processed area can be determined to be the area with clear display, the brightness of the area does not need to be adjusted, and the display screen can continue to maintain the previous brightness to display the display area.
For example, in the region to be processed, the pixels in the region 1 may be 2 ten thousand pixels, the gray value of the pixel point may be 200, the preset pixels are 2 ten thousand pixels, and the gray value of the pixel point may be 200, so that the definition of the region 1 meets the preset definition, and the display screen light source corresponding to the region 1 may continue to maintain the current brightness to display the region 1, which may effectively reduce the power consumption of the terminal.
In some embodiments, in order to ensure display consistency of the current display screen and improve user experience, if the to-be-processed area may be determined based on a difference in definition between each to-be-processed area, the step "determining the target processing area from the plurality of to-be-processed areas based on the image display information" may further include the following steps:
acquiring a definition difference value between every two to-be-processed areas;
judging whether the definition difference value is less than or equal to a preset difference value or not;
and if not, taking the to-be-processed area with smaller definition in the two to-be-processed areas as a target processing area.
Specifically, a definition difference value between every two regions to be processed is obtained, the definition difference value is compared with a preset difference value, and whether the definition difference value is smaller than the preset difference value is judged. The preset difference value can be expressed as a display definition difference which can be accepted by a user between the two to-be-processed areas.
If the definition difference value of the two to-be-processed areas is larger than the preset difference value, the to-be-processed area with smaller definition in the two to-be-processed areas can be determined as the target processing area.
For example, the region to be processed may include a region 1 and a region 2, where pixels in the region 1 may be 2 thousand pixels, a gray level value of a pixel may be 200, pixels in the region 2 may be 2 thousand pixels, a gray level value of a pixel may be 150, a pixel difference value between the region 1 and the region 2 is 0, a gray level difference value of a pixel is 50, a preset pixel difference may be 5000 pixels, and a gray level difference value of a preset pixel may be 20, and then it may be determined that a difference value of sharpness between the region 1 and the region 2 is greater than a preset difference value, and then the region 2 may be determined as the target processing region.
105. And adjusting the brightness of the target processing area.
Specifically, after the target processing region is determined, the brightness adjustment may be performed on the target processing region. In adjusting the luminance of the target processing region, the luminance of the target processing region may be adjusted with reference to the luminance value of a region adjacent to the target processing region.
In some embodiments, the step of "adjusting brightness of the target processing region" may include the following steps:
acquiring brightness information of a to-be-processed area adjacent to the target processing area;
determining the target brightness according to the brightness information;
acquiring the display position of the target processing area on the display screen;
and adjusting the brightness of the display position to the target brightness.
Specifically, the brightness information of the to-be-processed area adjacent to the target processing area is obtained, and the brightness information may include a display screen light source brightness value. After the brightness information of the to-be-processed areas adjacent to the target processing area is acquired, the target brightness can be determined according to the brightness information of the to-be-processed areas, wherein the target brightness is the final display brightness of the target processing area.
For example, the to-be-processed area adjacent to the target processing area may be an area a, an area B, an area C, and the like, the display luminance of the area a may be 170Lux (Lux), the display luminance of the area B may be 200Lux, and the display luminance of the area C may be 190Lux, and then the luminance average value of the area a, the area B, and the area C may be taken, and the average value may be used as the target luminance, that is, the average value 186Lux may be used as the target luminance of the target processing area.
After the target brightness is determined, the display position of the target processing area on the display screen can be obtained, and the display positions of the target processing area on the display screens of different terminals are different because the display screens of different terminals are different in size. The display position may include position coordinates and a region size. The brightness of the display screen at the display position can be adjusted to the target brightness, after the brightness of the target processing area is adjusted, the definition of the target processing area can be increased, meanwhile, the brightness difference value between the target processing area and the adjacent area is reduced, and the display quality of the picture of the display screen can be effectively improved.
In some embodiments, the step of "adjusting the brightness of the display position to the target brightness" may include the following steps:
determining an electric pulse signal according to the display position;
driving a light source corresponding to the display position to emit light based on the electric pulse signal;
and adjusting the brightness of the display position to the target brightness according to the light.
Specifically, the electrical pulse signal is determined according to the display position, and the electrical pulse signal may include a signal width and a signal amplitude. And then, the light source corresponding to the display position can be driven to emit light through the electric pulse signal, a bright light environment can be generated according to the light, and the bright light environment can be used for enhancing the brightness of the display position of the display screen.
For example, the light is driven by the electric pulse signal to form a bright light environment, the electric pulse is controlled to drive the display position light source in a centralized manner, the driving time of the display position light source is far shorter than the light emitting time of the light source, and the light sources in other areas are isolated, so that the light sources in other areas cannot emit light when the display position area is driven by the electric pulse. The electric pulse signal width can be correspondingly set to be narrow, namely the electric pulse signal width t is less than 0.5us (microsecond), the electric pulse signal width is used for outputting a plurality of electric pulses quickly and driving the light group to diffuse to quickly form a bright light ray area, wherein the light group can be light output by more than 2 light sources and forms the bright light ray area by driving the light group to diffuse.
The amplitude of the electric pulse signal can be set to be wide and can be larger than 2.8V, the electric pulse signal drives the optical group to form a bright light environment through wide amplitude, if the electric pulse signal can be in a very short time, namely time t is less than 0.01us, a plurality of electric pulses are output to drive the optical group to form the bright light environment, the electric pulse signal needs to output a signal t with narrow width to be less than 0.5us, at the moment, the electric pulse signal can drive the optical group fast, the time for generating the bright light environment is reduced, and the power consumption of the mobile terminal can be reduced.
The embodiment of the application discloses a file display processing method, which comprises the following steps: when the file is detected to be displayed, acquiring a display picture of a current display screen; determining a plurality of areas to be processed according to the display picture; acquiring image display information of a region to be processed; determining a target processing area from a plurality of areas to be processed based on the image display information; and adjusting the brightness of the target processing area. According to the embodiment of the application, when the file is displayed at the terminal, the area needing brightness adjustment is determined according to the definition of each area of the display picture, the brightness adjustment is further carried out on the area, full-screen brightness adjustment is not needed, the quality of reading the file by a user is guaranteed, and meanwhile the power consumption of the terminal can be effectively reduced.
Referring to fig. 2, fig. 2 is a schematic flowchart of a processing method for displaying a second file according to an embodiment of the present application. The specific scene application of the processing method for file display may be as follows:
201. and the terminal determines a display file according to the touch operation of the user and displays the display file on a display screen.
Specifically, when a user views a file through the terminal, the terminal can be started, corresponding touch operation is executed on a terminal interface according to a terminal prompt, the file is determined to be displayed, and the displayed file can be the file viewed by the user. The display file can be a video file, and the terminal displays the display file on the display screen according to touch operation of a user.
When the terminal displays the display file on the display screen, the display file may be displayed according to an initial display attribute of the display file, where the display attribute may include multiple types, for example, the display attribute may include a format, and the like.
For example, the display file may be a video file, the display attribute of the video file, that is, the display format may be a standard definition, and when the terminal displays the video file, the display file is displayed on the display screen in the standard definition format.
202. And the terminal acquires a display interface of the display screen at preset time intervals.
Specifically, the terminal acquires the display interface of the display screen at preset time intervals, when the terminal displays the display file, the display interface can be changed in real time according to the content of the display file, so that the area of the display interface to be adjusted can be changed at different display interfaces, the display interface of the display screen can be acquired at the preset time intervals, the terminal can rapidly adjust each area of the display interface in real time, and the adjustment efficiency of the display interface is improved.
203. The terminal acquires display information of a display interface and divides a display picture into a plurality of areas to be processed according to the display information.
Specifically, the terminal may obtain display information of the display interface after obtaining the display interface, where the display information may refer to display contents included in the display interface, for example, the display contents may include characters, character images, and the like.
After the display information of the display interface is acquired, the display screen can be divided into a plurality of areas to be processed according to the display information. Specifically, the display information may be characters, character images, and the like, and the terminal may divide character modules in different areas of the display interface into a plurality of areas to be processed, divide the character images into a plurality of areas to be processed according to different character images, divide a blank area that does not include the display content into one area to be processed, and the like.
204. And the terminal acquires the brightness difference between the areas to be processed.
Specifically, the terminal obtains the brightness difference value between the regions to be processed, and the terminal can calculate the brightness difference value between every two regions to be processed to obtain the brightness difference value between the regions to be processed, so that the brightness difference of different regions of a display picture can be determined, and the display picture can be quickly adjusted according to the difference.
For example, the regions to be processed may include a region 6, a region 7, a region 8, and the like, and first, the luminance value of each region to be processed may be obtained, where the luminance value of the region 6 may be 100 lux, the luminance value of the region 7 may be 150 lux, and the luminance value of the region 8 may be 180 lux, and then it may be determined that the luminance difference between the region 6 and the region 7 is 50 lux, the luminance difference between the region 6 and the region 8 is 80 lux, and the luminance difference between the region 7 and the region 8 is 30 lux.
205. And the terminal judges whether the brightness difference value is larger than a preset difference value or not.
Specifically, after the brightness difference values between the regions to be processed are obtained, each brightness difference value may be compared with a preset difference value, and whether the brightness difference value is greater than the preset difference value is determined, so that the region to be brightness-adjusted may be determined.
For example, if the predetermined brightness difference may be 50 lux, the brightness difference between the region 6 and the region 7 may be 50 lux, the brightness difference between the region 6 and the region 8 may be 80 lux, and the brightness difference between the region 7 and the region 8 may be 30 lux, then it may be determined that the brightness difference between the region 6 and the region 8 is greater than the predetermined brightness difference, and then step 206 may be performed on the region 6 and the region 8.
For another example, the predetermined difference may be 50 lux, and if the brightness difference between the regions to be processed is less than 50 lux, step 208 may be executed.
206. And the terminal determines the area to be processed with lower brightness value as the target processing area.
Specifically, when the brightness difference between the determined area 6 and the determined area 8 is greater than the preset difference, the terminal determines the area to be processed with a lower brightness value in the area 6 and the area 8 as the target processing area, and the target processing area may be an area requiring brightness adjustment.
207. And the terminal adjusts the brightness of the target processing area.
Specifically, the terminal adjusts the brightness of the target processing area, the terminal may obtain the brightness value of the to-be-processed area adjacent to the target processing area, the target brightness is determined according to the brightness value of the adjacent to-be-processed area, the target brightness may be the final display brightness of the target processing area, and then the brightness of the target display area may be adjusted to the target brightness to complete brightness adjustment.
For example, the areas to be processed adjacent to the target processing area may be an area 7 and an area 8, the luminance value of the area 7 may be 150 lux, the luminance value of the area 7 may be 180 lux, the luminance average value of the area 7 and the area 8 is obtained, that is, the luminance average value is 165 lux, it may be determined that the target luminance is 165 lux, and then the light source of the display screen corresponding to the target processing area is adjusted to 165 lux, that is, the luminance adjustment of the display screen may be completed, so that the definition of the display screen is improved and the user experience is improved on the premise of ensuring the uniformity of the display screen.
208. And the terminal finishes the operation.
Specifically, when the brightness difference values between the areas to be processed are smaller than the preset difference value, the display picture does not need to be adjusted, the current display brightness of each area can ensure that a user does not have an impression when viewing files, and the power consumption of the terminal can be reduced.
The embodiment of the application discloses a file display processing method, which comprises the following steps: when the file is detected to be displayed, acquiring a display picture of a current display screen; determining a plurality of areas to be processed according to the display picture; acquiring image display information of a region to be processed; determining a target processing area from a plurality of areas to be processed based on the image display information; and adjusting the brightness of the target processing area.
