What are the tens of thousands of pixels in the camera?

Pixel refers to the number of CCD or CMOS imaging units in the camera. Regardless of the shooting distance, the higher the pixel, the higher the image definition of the photo. The production requirements of CCD are relatively high, and the cost is also high, so many SLR cameras produced by manufacturers generally use CMOS imaging, which can reduce the cost and the price is low. Generally speaking, photos taken by a 5-megapixel camera can be enlarged to more than 20 inches. Good marksmanship, of course!
