Detailed Description
The terminology used in the description of the embodiments section of the present application is for the purpose of describing particular embodiments of the present application only and is not intended to be limiting of the present application.
As shown in fig. 1, an embodiment of the present application provides a screen display method, including:
step 101, reading an identification compressed file when the electronic equipment is in a preset scene state;
and 102, taking an identification file corresponding to the current preset scene state in the identification compressed files as a target file for decompression, and displaying an identification according to the decompressed target file.
Specifically, for example, the identified picture file is compressed at the stage of compiling the operating system image file, and the compressed file is written to the operating system. In step 101, the preset scene state is a specific state of the electronic device, for example, an initial power-on state of the electronic device, and in this state, the data of the target file at the specified address is extracted and decompressed to the specified memory address, and the corresponding identifier is displayed according to the decompressed target file.
According to the picture display method in the embodiment of the application, the identification compressed file is read and decompressed, the decompressed identification file is obtained, the identification is displayed according to the decompressed identification file, and due to the compression of the identification file, the identification corresponding to more scenes can be stored, namely, the identification display can be realized in more scenes.
In a possible embodiment, as shown in fig. 2, the markup compressed file includes header information and a plurality of markup files, the markup files may be, for example, files in a bin format, for example, the plurality of markup files include a first markup file logo1.Bin, a second markup file logo2.Bin, a third markup file logo3.Bin, \\ 8230, and an nth markup file logon. Bin, each markup file corresponds to a preset scene state, different markup files correspond to different preset scene states, the header information includes a correspondence between the plurality of markup files and different preset scene states, for example, the markup file corresponding to the initial power-on state in the header information is the first markup file logo1.Bin, and the markup file corresponding to the battery low-voltage state is the third markup file logo3.Bin; as shown in fig. 3, the step 102 of decompressing, as the target file, the markup file corresponding to the current preset scene state in the markup compressed files, and displaying the markup according to the decompressed target file includes:
step 1021, acquiring a current preset scene state;
step 1022, reading the header information, and taking the identification file corresponding to the current preset scene state as a target file according to the header information;
step 1023, decompressing the target file;
and step 1024, displaying the identification according to the decompressed target file.
Specifically, for example, the identified picture file is compressed at the stage of compiling the image file of the operating system, and assuming that the identified picture file includes a file in the bmp format, the bmp file can be compressed into a bin file, the compression rate of the file is high, and the compression rate of the file can reach 96% in the test, that is, the bmp file with the size of 5Mb, for example, can be compressed into the size of 10 to 20 kb. As shown in fig. 4, the first identification picture file logo1.Bmp is compressed into the first identification file logo1.Bin, the second identification picture file logo2.Bmp is compressed into the second identification file logo2.Bin, the third identification picture file logo3.Bmp is compressed into the third identification file logo3.Bin, and so on until the nth identification picture file logo. Bmp is compressed into the nth identification file logo.bin, in order to ensure the integrity of the compressed files, the scattered plurality of compressed identification files are spliced, the spliced files are temporary identification files temp _ logo.bin, the temporary identification files are sequentially spliced by the first to nth identification files, and header information header _ info is added to the header of the temporary files to form the identification compressed files final _ logo. And replacing the original picture file in the bmp format with the identification compressed file final _ logo. The markup files in the markup compressed file can be arranged in sequence according to the sequence numbers, for example, the first markup file is a first markup file logo1.Bin, the second markup file is a second markup file logo2.Bin, and so on, and the last markup file is an nth markup file logo1. Bin. The function of step 1011 is to determine what identifier the electronic device needs to display currently, for example, assuming that the current preset scene state obtained in step 1011 is low battery level, a target file in the multiple identifier files is determined in step 1012 according to the header information, and since the current preset scene state is low battery level, a corresponding third identifier file logo3 is determined as the target file according to the header information, and then the third identifier file logo3 is decompressed in step 103, and a corresponding identifier is displayed according to the decompressed third identifier file logo3 in step 1014.
In one possible embodiment, the header information further includes a size of each identification file; as shown in fig. 5 and 6, before decompressing the target file in step 1023, the method further includes:
step 10220, determining the start address of the target file according to the start address of the header information, the size of the header information, and the size of each markup file before the target file;
step 1023, decompressing the target file comprises: and 10230, decompressing the target file according to the initial address and the size of the target file.
Specifically, the markup files in the markup compressed file are arranged according to a preset setting, that is, each markup file before the target file is known, for example, the markup compressed file is formed by sequentially arranging and splicing according to the order from the first to the nth, and the fourth markup file is the target file, then the start address of the target markup file can be obtained only by adding an offset to the start address of the header information, where the offset = the size of the header information + the size of the first markup file + the size of the second markup file + the size of the third markup file, and the target file can be obtained according to the size of the target file.
In one possible implementation, the compressed file is identified as a bin format file and the identified file is identified as a bin format file. In addition, in order to be compatible with the existing logo display method, a picture file in the bmp format may be added to the logo compressed file.
In one possible implementation, as shown in fig. 7 and 8, the step 1024 of displaying the identifier according to the decompressed target file includes:
step 10241, determining and extracting effective pattern data of the decompressed target file through a data recognition algorithm;
step 10242, display the identified pattern based on the valid pattern data.
Specifically, in the process of decompressing the target file in step 10230, the data of the target file may be read and decompressed to a specified memory address to obtain all the data of the decompressed target file, a start address and an end address of effective pattern data may be found out in a memory area corresponding to the decompressed target file through a data recognition algorithm, the identification picture has a pattern and a background, the effective pattern data refers to an area having pattern features, the effective pattern data is extracted through an address and a size of the effective pattern data to perform image processing and output for display, in the process of display, a long-wide pixel value of the display panel may be determined, the effective pattern is displayed on the display panel horizontally in a centered manner, and for the vertical direction, the display position may be freely adjusted through a preset start height. In this way, the data processing amount of the target file can be reduced by determining and acquiring the effective pattern data through the data recognition algorithm. The picture display process of the electronic equipment in the preset scene state is different from picture display in a common scene, the picture display in the state aims to prompt the user that the electronic equipment is in a specific current state, and the state is different from other states in normal work, such as an initial power-on state, a battery low-voltage state or a power-off charging state, so that a picture needing to be displayed by the electronic equipment in the process is usually a pattern with obvious characteristics in a middle area of a display screen under a pure-color background so as to efficiently prompt the specific current state of the electronic equipment for the user.
In a possible implementation, as shown in fig. 7, the step 1024 of displaying the identifier according to the decompressed target file further includes:
step 10243, determining invalid pattern data of the decompressed target file through a data recognition algorithm, and extracting a background color according to the invalid pattern data;
step 10244, display the identified background based on the background color.
Specifically, the clipping of the effective pattern, i.e., the extraction of the effective area data, can be realized by the steps 10241 and 10242 to realize the display of the effective pattern content in the effective area, the step 10243 can realize the extraction of the background color, and the step 10244 can fill the extracted background color outside the effective area in the display panel to realize the more efficient background display without image processing on all the data in the target file. For a scene displayed by a logo, usually, only a part of effective patterns need to be displayed in a large piece of solid background, so that the extraction and processing of effective area data and the extraction of background colors in the embodiment of the application can increase the processing efficiency and save the memory space.
In one possible implementation, the preset scene state includes a power-on state, a battery low-voltage state, a power-off charging state, and the like.
