Working principle of the color palette)

The display can be set to 16, 256, 64 K, true color, and other display modes. The first two modes require a color palette. In 16 or 256 color mode, Program You must correctly set the color you want to display to the color

Logical color palette and system color palette

First, we will explain the concept of Bitmap and palette with common statements. We know that all colors in nature can be composed of red, green, and blue (R, G, B. It can be divided into 0 ~ There are 255 levels, and different combinations of red, green, and blue are 256x256x256, so they can represent 16 million colors (16 m ). For human eyes, this is already "true color. This is a 24-Bit Bitmap or a large

values, 256 green values, and 256 blue values, all the colors that can be obtained are about 1. 670 million (256 x 256 x 256) species. It looks like it's already a lot of colors, but don't forget, these are just a few of the colors that are visible in nature. However, 1. The 670 million colors are sufficient to replicate crystal-clear digitized images on a monitor that is connected to a computer that is equipped with a 24-bit color. In this section,

data of the memory or display in a bits without being compressed, therefore, it is called a bitmap file. Because its file extension is BMP, it is called a BMP file format, or BMP file for short. The Algorithm Programming of images in this book is aimed at BMP image files. Therefore, we will introduce the structure of BMP files and Their read/write operations in detail in this chapter to deepen our understanding of image data. A bmp file consists of four parts: the bitmap file header, b

(red), when a pixel is red, you only need to indicate0. Let's calculate it again: 16 states can be expressed in 4 bits, so a pixel needs to be halfBytes. The entire image should contain 200*200*0.5, about 20 K bytes, plus 3*16 = 48 bytes in the preceding table.The total number of bytes occupied is about 1/6.This RGB table is also called the color palette (palette

specific set of colors (such as a color palette), and then deleting the unused colors in the image, you reduce the number of colors used in the file, and the size of the file is correspondingly reduced. However, the number of colors is too few to affect the quality of the image, so the user must test the effects of various palettes to find a balance between the image size and quality. As shown in Figure 2.

[Conversion] LCD palette

For a display device, the data update rate is proportional to the product of the number of frames and the color depth. In an embedded Linux system, the CPU resource configuration and computing capability are restricted. When large resolution is used for display (for example, on some terminals with large screen sizes, usually 640 × 480 or more), to reduce the color depth of the display. Otherwise, image jitt

Therefore, "A: Social Networking" has the greatest value;I

Principle of Converting color BMP into Grayscale Images

In image processing, most of the processing methods need to convert a color image into a grayscale image in advance for calculation and recognition.The principle of converting a grayscale image from a color chart is as follows:We know that the color bitmap consists of three components: R/G/B, and its file storage format isBitmapfileheader + bitmapinfoheader:If it
