An Interesting Patent by Canon

Camera manufacturer Canon applied for a patent for the invention of the lens that cleans the dust inside the device.

The lens, whose patent application filed in Japan, takes air inside, this air creates a vortex in the image sensor inside the body of the camera, and then this air comes out. In this way, the camera gets rid of internal dust that causes dark spots in photos.

Also, the lens developed by Canon draws in the air outside through the channels around the outer frame on the front side. This air is directed into the mirror box of DSLR. Meanwhile, the mirror rises and the sensor remains open. Then, this dusty air is ejected through channels around the lens.
