The purpose of this study is to construct a model of an optical lens by using a multi camera array. It is known that
virtually focused images can be produced by synthetic aperture focusing techniques. However there is a difference
between the blur of the virtually focused image and the blur of an image produced by an optical lens. We suggest a method
to correct this difference. Using our method, it is possible to create images that have multiple discrete focus depths,
something that is impossible using an optical lens. Basic experiments were conducted, and the effectiveness of the
approach was demonstrated.
