After signal comparison signals during focus information periods set until optimum correlation result. To realize both undisturbed scene as focusing while using one same purpose it operates consecutively television field period (TV) (TVS), (TFV) between at least (TAS TBS, respectively), first second being (TFA TFB, respectively)
