Resolution and Pixel of Digital Camera

When we come across digital cameras, we often see such parameters as "2304X 1728, 1600X 1200,1027x768,640x480", which is also commonly known as the resolution. So what do they mean? I believe that mosaics are well-known building materials, so these parameters are like the number of horizontal mosaics multiplied by the number of vertical mosaics, and each mosaic represents a pixel. A picture is made up of these colorful mosaics. Enlarge the part of the lotus in the picture below by 1600 times, and we can clearly see that the color blocks of the mosaic are actually the corresponding pixels.

The highest shooting resolution of a camera is generally similar to its pixels. Take 2304X 1728 given above as an example, then the maximum effective image number of this camera is 2304 *1728 = 3981312, and the approximate value is 4 million. In other words, this is a 4 megapixel digital camera. Similarly, we can also calculate the pixels corresponding to other camera resolutions. The author gives the corresponding reference table here. Of course, the camera settings are different, which may be different. Generally, as long as you choose a camera from a specific manufacturer, the given resolution is fixed, and users can switch between different resolutions but can't customize the resolution.
