The front camera has the function of 720P high-definition photography. What does 720p mean?

720P refers to the high-definition video with the screen resolution of 1280×720, where 720P refers to the vertical pixels of the video. Nowadays, popular high-definition movies and videos refer to 1080p, and 720p refers to the definition. 1080 is actually1920×1080,720 stands for 1280×720. But don't think that the resolution of 720 is necessarily lower than 1080. In fact, P of 720P refers to progressive scanning, and I of 1080i refers to interlaced scanning, which is also a scanning frequency. Progressive images are more stable, flicker-free and better than interlaced images! In fact, the effect after 1080i conversion is only equivalent to 540P, which is definitely not as good as 720P.
