Embodiment Construction
[0014] The present invention will be described in detail below in conjunction with specific examples.
[0015] According to the imaging principle of the convex lens, when the object forms a clear image, there is
[0016] Where u is the object distance, f is the focal length of the convex lens, and v is the image distance. It can be obtained from the above formula that as long as any two parameters are determined, the other parameter is also determined.
[0017] The lens of a digital camera is composed of multiple groups of lenses. When focusing, by adjusting the different positions of each group of lenses, within the focal length range of the lens, the focused object can form a clear image on the photosensitive element. When the digital camera finishes focusing on an object, the lens barrel stops stretching. At this time, the focal length value of the lens is determined, and the position of the CCD is also determined, so the image distance v at this time can also be determ...
