ABSTRACT:
An autofocus device and method for a camera that can process statistically the tracking and focusing of an object in high velocity motion. The device and method corrects the acceleration of the motion and computes a lens forwarding amount and an absolute position of the object. This is achieved by a camera system including a camera body and a focus lens. The camera body includes an autofocus detector, an autofocus processor section and a main CPU. The focus lens includes a lens, a lens driving gear, a lens CPU, and a motor. This structure, having an improved autofocus processor, enables highly accurate prediction tracking and autofocus control that accommodates fluctuations in an autofocus operation.
