What is the concept of12 million pixels?

Is a concept that describes the number of pixels that a camera or image sensor can capture.

In digital photography, pixels are the basic unit of an image, and their number determines the clarity and detail of the image. 12 million pixels means that a camera or image sensor can capture and process12 million pixels to generate an image composed of these pixels. Specifically, a higher number of pixels usually means that the image has a higher resolution and can display more details and clearer images. Therefore, the image with 6.5438+0.2 million pixels can still maintain high definition when it is enlarged or cropped.

The number of pixels is not the only criterion to measure the image quality. Other factors, such as lens quality, sensor technology and image processing algorithm, will also have an important impact on image quality. Therefore, when choosing a camera or evaluating the image quality, besides the number of pixels, other related factors should be considered.
