What does 3mp mean?

Camera 3MP represents camera lens 3 million pixels. MP in 3MP is the abbreviation of Megapixel. If the aspect ratio is 16:9, the resolution should be 2048 times 1536.

Megapixel lens is also called high-definition lens, and it can only be called megapixel lens when it reaches 720 pp. In the past, it was generally believed that the interlaced image clarity of 4CIF(704×576) or D 1(720×480) can be called megapixel lens. Megapixel lenses are divided into1500,000 pixel lenses and 5 million pixel lenses.

Digital camera is a product integrating optics, machinery and electronics. It integrates the conversion, storage and transmission of image information, and has the characteristics of digital access, interactive processing with computer and real-time shooting. Light enters the camera through a lens or lens group, and is converted into a digital signal through an imaging element of a digital camera, and the digital signal is stored in a storage device through an image operation chip. The imaging element of digital camera is CCD or CMOS, which is characterized in that when light passes through it, it can be converted into electrical signals according to different light. Digital cameras first appeared in America. More than 20 years ago, the United States used it to transmit photos to the ground via satellite. Later, digital photography was converted to civilian use, and its application scope continued to expand.
