Camera resolution refers to the size of an actual object expressed in pixelsum*umIndicated. The smaller the value, the higher the resolution.FOVIt refers to the actual shooting area of the camera being millimeters×Expressed in millimeters. In an image, the expression of image details is not determined by the number of pixels, but by the resolution. The resolution is determined by the focal length of the selected lens. For the same camera, lenses with different focal lengths have different resolutions.

Since the number of pixels does not determine the resolution (clarity) of an image, what are the benefits of a large-pixel camera? There is only one answer: Reduce the number of shots and increase the testing speed.
