Mega pixels是甚麼意思

"Mega pixels" (MP) is a term used to describe the resolution of digital images and cameras. It refers to one million (1,000,000) pixels, which are the tiny dots that make up an image. The more megapixels a camera or image has, the higher its resolution and the more detail it can capture. High-resolution images are desirable because they can be enlarged without losing detail, and they can produce high-quality prints. However, more megapixels also mean larger file sizes, which can take up more storage space and may take longer to transfer or upload.
