摘要： An automatic focus adjusting apparatus of a camera calculates amount of defocus of an object, and repeatedly calculates the speed of the image plane of the object based on the amount of defocus. When releasing operation of the camera is started, image plane speed of the object at the time of exposure is estimated by using a secondary curve based on the speed of the image plane, and the lens is driven based on the data thereof. Since the image plane speed of the object is estimated by using the secondary curve equation, correction of the amount of defocus can be accurately done regardless of the speed of movement of the object.
