    • An automatic focusing device for camera is provided which makes it possible to sequentially photograph a large number of frames while ensuring a high focusing accuracy. A first focusing unit carries out a first focusing operation. After the first focusing unit carries out the first focusing operation, a second focusing unit carries out a second focusing operation. A storage device stores a difference in results obtained by the first and second focusing operations. In sequential shooting, a controller causes the first focusing unit to correct the result of the first focusing operation according to the stored difference, and inhibits the second focusing unit from carrying out the second focusing operation.
    • 提供一种用于照相机的自动对焦装置,其可以在确保高聚焦精度的同时顺序拍摄大量的帧。 第一聚焦单元执行第一聚焦操作。 在第一聚焦单元执行第一聚焦操作之后,第二聚焦单元执行第二聚焦操作。 存储装置存储通过第一和第二聚焦操作获得的结果的差异。 在顺序拍摄中,控制器使得第一聚焦单元根据存储的差异校正第一聚焦操作的结果,并且禁止第二聚焦单元执行第二聚焦操作。
