"Pixel" consists of letters of the words "picture" and "element", which is the unit used to calculate digital images. Just like photos, digital images have continuous shadows. If you enlarge the image several times, you will find that these continuous tones are actually composed of many small squares with similar colors, which are the smallest unit "pixels" that make up the image. This smallest graphic unit can usually display a coloring point on the screen. The higher the pixel, the richer the sample and the more realistic the color is.
The photo we took is made up of n pixels. The more pixels, the bigger the picture. You can see the resolution of the monitor. If it is 1024*968, then it is 1024dpi high and 968dpi wide.
