Zusammenfassung:	An automatic lens detecting method is used for detecting the imaging quality of a lens, and includes steps as follows: an image collection module receives the image information from the lens, and sends the acquired image information to a positioning module; the positioning module positions the positions of a plurality of areas whose image information is required to be detected, and sends the positions of the areas to an image processing module; the image processing module calculates the contrast ratio of the image information in the position of each area, and outputs the contrast ratio to an output module; and the output module compares the contrast ratio with a preset standard contrast ratio to determine the imaging quality of the lens. Compared with the prior art, the method calculates the contrast ratio in the position of each area, and the output module compares the contrast ratio with the preset standard contrast ratio to determine the imaging quality of the lens.
