Abstract:
The present disclosure overcomes the limitations of the prior art by using blurring of edges. For example, a first image may contain an edge and a second image may contain the same edge as the first image. The two images may be captured by imaging systems with blur characteristics that vary differently as a function of object depth. For example, a dual-aperture system may simultaneously capture a faster f-number visible image and a slower f-number infrared image. Depth information may be generated by comparing blurring of the same edge in the two images.
