Using Two Lenses for Depth Estimation and Simulation of Low Depth-of-Field Lenses

One of such possibilities that has yet to be explored in the literature, is using inexpensive 2-lens cameras to simulate the artistic effect of low depth-of-field (DOF) lenses. These low DOF images which maintains focus on a small area of the scene, and blurs out the background are often the hallmark of professional and artistic photography. The way these lenses achieve low DOF is by using large apertures. Unfortunately, these low DOF lenses are very expensive themselves and can only be used in expensive digital single lens reflex (DSLR) cameras. One viable alternative is to use inexpensive 2-lens cameras to simulate the out of focus blurring effect of high-end lenses and cameras.
