Abstract:
The present application discloses a lens, camera, package inspection system and image processing method. The lens comprises an optical lens and a photosensitive chip, and further comprises an optical filter comprising a first filter portion and a second filter portion and disposed between the optical lens and the photosensitive chip, wherein a first object point is imaged on the photosensitive chip through the optical lens and the first filter portion, and a second object point is imaged on the photosensitive chip through the optical lens and the second filter portion, the first filter portion having a thickness greater than that of the second filter portion. The technical problem of a lens in relevant art having a relatively small DOF is solved by the present application.

Claim (Index 15):
The method of  claim 14 , wherein before obtaining the first target image and the second target image, the method further comprises:\n obtaining a first proportion and a second proportion, wherein the first proportion is the proportion of the image of the target object to be detected in a first region of the image to be processed, and the second proportion is the proportion of the image of the target object to be detected in a second region of the image to be processed; determining whether the difference between the first proportion and the second proportion reaches a predetermined threshold, wherein the first proportion is larger than the second proportion; and adjusting the position of the optical filter to increase the second proportion and re-obtaining the image to be processed if it is determined that the difference between the first proportion and the second proportion reaches the predetermined threshold.
