How to explain the pixel of mobile phone?

The so-called "pixel" of a digital camera refers to the "resolution" of the picture that can be seen on our computer monitor, that is. What is the resolution? This is the display size of your computer. For example, a digital camera with 800X600 or 1024X768 can take photos with a length of 1024 and a height of 768 (resolution) (that is, the photos of a digital camera with 800x600 can fill the screen on your monitor. 300 Vientiane digital cameras can take photos with a length of 2048 and a height of 1536 (resolution). You must drag the scroll bar to browse all parts of the image. 400 Vientiane -500 Vientiane is larger in size. Pixel refers to the size of the picture (regardless of photo quality). Pixel-resolution = picture size (don't think that pixel and resolution are image sharpness). If you don't understand, look at the photos taken by 200 Vientiane cameras below. The photos taken by 300 Vientiane cameras are generally large (on the monitor), and the photos taken by 500 Vientiane cameras (on the monitor) are very large. 1000 photos taken by Vientiane camera (on the monitor) are so big that this means ~ 200 Vientiane digital cameras, the maximum size (pixel) you can take is a photo of length 1600 height 1200. After transmission to the computer, the image is enlarged to 2048X 1536 by software. You can also say that this image is a 300 Vientiane image (this is called software interpolation). Many cameras say (100 Vientiane interpolation is 200 Vientiane). For example, many Fuji machines are interpolated from 300 Vientiane to 600 Vientiane. In fact, the enlarged image quality is not as good as the original image, which has no practical significance. Then you know what a pixel is! So when you buy a digital camera, you must look at the image quality of the machine you want to buy. It is not feasible to look at pixels blindly. As long as the image taken by 80000 Vientiane digital camera can be enlarged to 1000 Vientiane ... 2000 Vientiane software ... but if you look at the enlarged image, you will feel that the pixel is = what is the image quality? Look at the photos of the digital camera you want to buy. For example, two different brands of 400 Vientiane digital cameras have different picture quality in the same position and under the same light (under exactly the same shooting conditions). This is the detail expression ability we discussed. It doesn't mean that a photo with a large pixel must look good but not rough, and the quality of the photo has little to do with the pixel. The quality depends on the compression ratio of lens CCD and the output of color management system.
