If a means to broadcast become diversified and still more programs are demanded, to advance and simplifying technique of making contents are necessary. When we input the posture of agent to operate the virtual CG actor, we want to not use a special studio and devices. In this paper, we suggest the extracting method from a picture by using defocusing estimation. If the object in picture is in focus, others in picture are out of focus. Then, this method extracts the object by estimating defocuses each pixel using partial autocorrelation and removing parts have a great distance from a focus. We make the experiment with a picture that is in focus taken by Digital Camera, and a satisfactory result is obtained.
