Description

Start-up method of computer system and processing method of start-up screen

technical field

The invention relates to a processing method of a start-up picture, and in particular to a processing method of a start-up picture related to the technology of merging colors.

Background technique

When a computer system is turned on, a startup screen will be displayed on its screen, as shown in FIG. 1 . FIG. 1 is a boot screen diagram of a computer system. Generally, the start-up screen may include text information and a start-up pattern, for example, the prompt information at the bottom of Fig. 2 is text information.

In addition, if the computer system uses a processor of a certain brand, there will be a screen mark of the brand in the lower right corner or upper right corner of the startup screen shown in FIG. 1 , as shown in FIG. 3 . That is to say, in some startup screens, text information screens, screen marks, and startup patterns are included.

Taking the current computer system as an example, due to factors such as system compatibility and file size, the display mode of 256 colors is used when the computer system is turned on. That is to say, when the computer system is turned on, 256 colors can be provided to form the startup screen. Generally speaking, the number of colors used in the text information screen (as shown in FIG. 2 ) and the screen mark is fixed, and they are all 16 colors. That is to say, the computer system can provide 224 colors for the boot pattern.

However, since the boot pattern can be specified by the user, the required number of colors is not fixed. If the required colors for the boot pattern exceed 224 colors, there will be distortion in the boot screen. The known solution is to use drawing software to first open the boot pattern, and then use the recognition of human eyes to delete some similar colors until the number of colors forming the boot pattern is less than or equal to 224 colors.

As can be seen from the above, the known technology is to use manpower to process the colors that make up the boot pattern. Thus, known techniques are not efficient to implement. In addition, since everyone has different sensitivity to color, there is no uniform standard for processing the boot logo, resulting in unnatural color performance of the processed boot logo. In addition, processing the boot pattern through known techniques will permanently damage the boot pattern.

In this way, the processing method of the present invention can merge some colors in the color gamut distribution of the boot pattern into a single color according to the above-mentioned calculation value, so as to reduce the number of colors that make up the boot pattern, and generate at least the latest boot pattern startup screen.

In addition, the present invention can further provide text information screens and screen marks.

In an embodiment of the present invention, the above-mentioned step of reducing the number of colors that make up the boot pattern includes calculating the distance between the color value of each color and the color values of other colors in the color gamut distribution of the boot pattern, and obtaining multiple distance value. Also, compare the magnitudes of these distance values. When there is only a minimum distance value among the distance values, the two colors with the minimum distance are combined into a single color, so as to reduce the quantity of the above-mentioned colors forming the start-up pattern.

In addition, if there are multiple minimum distance values in the distance value, compare the number of occurrences of the two color values corresponding to each minimum distance value in the color gamut distribution of the power-on pattern. In this way, the present invention can combine the colors corresponding to the two color values having the smallest distance value and appearing the least times in the color gamut distribution of the boot pattern into a single color, so as to reduce the number of these colors forming the boot pattern.

From the above, it can be seen that the processing method proposed by the present invention can combine some colors forming the start-up pattern into a single color, so as to reduce the number of colors forming the start-up pattern. Thereby, the present invention can efficiently process the start-up picture, and make the color expression of the start-up picture more natural.

The CPU 402 is coupled to a chipset 404 , and is coupled to a BIOS unit 406 and a memory 408 through the chipset 04 . In general, chipset 404 may include, for example, a north bridge chip and a south bridge chip.

FIG. 5 is a flow chart showing the steps of a booting method of a computer system according to a preferred embodiment of the present invention. Please refer to FIG. 4 and FIG. 5 together. When the computer system 400 is turned on, it can perform a power-on self-test (POST) as described in step S502, and the BIOS program code embedded in the BIOS unit 406 can be decompressed, and then passed through the chipset. 404 is loaded into the memory 408 for execution, that is, the content of step S504. In this embodiment, the BIOS unit 406 can be implemented by using a flash memory. In addition, the memory 408 can be a random access memory (DRAM), a synchronous random access memory (SDRAM), or a doubling random access memory (DDRAM).

In particular, when the BIOS program code is loaded from the BIOS unit 406 into the memory 408 for execution, the boot pattern can be decompressed. In this embodiment, the boot pattern, as shown in FIG. 3 , can be composed of multiple colors, and its format can be a bitmap file, and can be compressed and stored in the BIOS unit 406 . By decompressing the boot icon, this embodiment can proceed to step S506, which is to provide text information, screen marks and the decompressed boot icon. It should be noted that after the boot pattern is decompressed, it does not need to be stored back into the BIOS unit 406 . Therefore, the source file of the boot pattern will not be changed in any way. Wherein, the so-called text information can be, for example, the text prompt information shown in the lower left corner of FIG. 2 .

Please continue to refer to FIG. 4 and FIG. 5 , after step S506 is completed, this embodiment can adjust the number of colors forming the boot pattern as described in step S508 . In this way, the present embodiment can generate a startup screen according to the text information screen, the screen mark and the startup pattern, and display it to the user when the computer system 400 is turned on.

FIG. 6 is a flow chart showing the steps of a method for processing the start-up screen according to a preferred embodiment of the present invention, which can be applied to step S508 in FIG. 5 . Please refer to FIG. 6 . In this embodiment, when processing the above-mentioned text information screen, screen mark and boot pattern, the color wheel data may be firstly provided as described in step S602 . In the color wheel data, multiple colors can be provided to process the startup screen of the computer system. In this embodiment, the color wheel data can provide, for example, 256-color color data. Wherein, these color data have corresponding color values in the color gamut distribution.

In addition, the processing method of this embodiment can perform steps S604 and S606, which is to calculate the number of colors that make up the text information screen and the screen mark. In this embodiment, the text information screen and the screen mark can be composed of 16 colors respectively. For example, the colors that make up the text information screen can include black, blue, green, cyan, red, purple, brown, white, dark gray, light blue, light green, light cyan, pink, light purple, yellow, bright White. In addition, in some optional embodiments, the 16 colors that make up the text information screen and the screen mark can be respectively configured in the first and last 16 color data of the color wheel data.

Next, the processing method of this embodiment can go to step S608, which is to calculate the number of colors that make up the boot pattern. Since the colors that make up the text message screen and the screen mark are relatively fixed, the number of colors that make up the boot pattern is not fixed because the user can specify it. Therefore, in this embodiment, as described in step S610, it may be checked whether the number of colors currently forming the boot pattern is greater than the preset value of the number of colors provided by the color wheel data. Assuming that the color wheel data can provide up to 256 colors of color data, and the number of colors that make up the text information screen and the screen mark is 16 colors as mentioned above, then the colors that the color wheel data can provide for the boot pattern may only be 224 colors. In other words, the preset value in step S610 may be equal to 224.

When the number of colors required by the boot pattern selected by the user exceeds the number of colors (for example, 224) that the color wheel data can provide to the boot pattern (that is, "yes" marked in step S610), then the present embodiment The processing method may calculate the color value of each color in the color gamut distribution of the current boot pattern with the color values of other colors to obtain a plurality of calculated values (step S612 ). In this way, the present embodiment can combine the colors of the start-up pattern into a single color according to these calculation values (step S614 ), so as to reduce the number of colors forming the start-up pattern.

Next, in the processing method of this embodiment, step S610 may be repeated after step S614 is performed. If the number of colors that make up the boot pattern still exceeds the preset value of the number of colors provided by the color wheel data, then continue to repeat steps such as steps S612 and S614 until the number of colors required for the boot pattern is less than or equal to that provided by the color wheel data. The default value for the number of colors. If the number of colors that make up the boot pattern is less than or equal to the preset value (such as 224) (that is, "No" indicated in step S610), then this embodiment can be described in step S616, according to the text information screen, the screen mark and the boot pattern. pattern to generate the startup screen.

In this embodiment, there may be many kinds of operation methods of step S612, such as Dithering method, Floyd-Steinberg algorithm, etc., which are not limited in this embodiment. In addition, the present invention provides an algorithm to process the number of colors of the boot pattern, as shown in FIG. 7 .

FIG. 7 is a flow chart showing the steps of a method for reducing the number of colors constituting the start-up pattern according to a preferred embodiment of the present invention. Please refer to FIG. 7, when the startup pattern is checked in step S612 of FIG. 6, for example, the required color quantity is greater than the preset value of the color data quantity provided by the color wheel data, then it can be as described in step S702. , in the color gamut distribution of the boot pattern, calculate the distance between the color value of each color and the color values of other colors, and obtain multiple distance values.

Suppose, the color value of one of the colors constituting the start-up pattern can be represented by (R1, G1, B1), and the color value of the other color can be represented by (R2, G2, B2). And step S702 can be represented by the following mathematical formula:

d=(R2-R1) ² +(G2-G1) ² +(B2-B1) ²

Among them, d is the distance value of the two color values in the color gamut distribution, and the R1, R2, G1, G2, B1, B2 values represent the red, green and blue components of the color respectively.

After these distance values are calculated, the present embodiment can compare the sizes of these distance values (step S704), and find the smallest distance value among these distance values (step S706). In this embodiment, it may also be determined whether there are multiple minimum distance values as described in step S708. If there is only one minimum distance value among these distance values (that is, "No" indicated in step S708), the colors corresponding to the two color values with the minimum distance value are merged into a single color.

Relatively, when there are a plurality of distance values that are the minimum value among the distance values and are equal to each other (that is, "yes" indicated in step S708), then as described in step S712, compare the values corresponding to each minimum distance value The number of times the two colors appear in the gamut distribution of the boot pattern. In addition, in this embodiment, as described in step S714, the color with the smallest distance value and the least number of occurrences in the color gamut distribution of the power-on pattern can be combined into a single color. Thereby, this embodiment can effectively reduce the number of colors constituting the boot pattern.

To sum up, because the present invention can use some algorithms to combine some of the colors used to form the boot pattern into a single color. Therefore, the present invention can effectively reduce the number of colors constituting the start-up pattern, so that the start-up picture of the computer system can be more natural.

In addition, in the present invention, since the boot pattern is compressed and stored in the storage area, it will not be decompressed and processed until the system is booted. Therefore, the original boot pattern will not be destroyed.

Although the present invention has been disclosed above with preferred embodiments, it is not intended to limit the present invention. Anyone with ordinary knowledge in the technical field may make some modifications and changes without departing from the spirit and scope of the present invention. modification, so the scope of protection of the present invention should be defined by the claims.
