Abstract
A method for testing a focusing characteristic of a camera may include setting a camera to align the camera and a first chart structured to provide a first scene for testing such that the camera is focused on the first chart disposed at a first distance from the camera, measuring a blur in an image of a second chart captured at a second distance from the camera, the second chart being structured to provide a second scene for testing, and evaluating a phase difference range (PDR) of the camera based on the measured blur and a blur calculated through a circle of confusion (CoC) model.
