We introduce a new concept called defocus morphing in real aperture images in this paper. View morphing is an existing example of shape preserving image morphing based on the motion cue. We prove that images can also be morphed based on the depth related defocus cue. This illustrates that the morphing operation is not necessarily a geometric process alone; one can also perform a photometry based morphing wherein the shape information is implicitly buried in the image intensity field. A

Mathematically we show that, given two observations of a 3D scene for different camera parameter settings, we can obtain a virtual observation for any camera parameter setting through a simple nonlinear combination of these observations.
