Imaging device and method based on difference compound eye lens

The invention discloses an imaging device and method based on a difference compound eye lens. On the basis of the structure of the compound eye lens and an imaging principle, images are formed on a photoelectric sensor through the compound eye lens and the combination between a propagation function feature extraction technology and a difference image processing technology, image region segmentation, propagation function processing and information difference processing are conducted on the images, and finally, image fusion is conducted, so that output of the needed image and needed information is achieved.
