Depth of Field Control Method for Small Digital Still Camera

Abstract

By the photography, there is the expression technique to let a person of appreciation watch a main subject closely by shading off a background with a focus on a main subject such as people. However, depth of field is deep and cannot satisfy a demand for the photograph expression of the user to shade off the background of the subject because there is it for a one-severalth of the film camera at the size of the imaging element with almost digital cameras. Therefore, in this study, a method to correct the depth of field of images photographed by digital cameras in degree same as film cameras are suggested to by software.
