    • An object of this invention is to provide an autofocus method and apparatus capable of always performing proper focusing operation. To achieve this object, a control device drives a focus lens in accordance with the operation of an operation device, and stores the stop position of the focus lens. While the focus lens is driven within a predetermined range using the stop position as a reference, the control device stores an output from an extraction device in association with the position of the focus lens. The control device determines the focusing state of the focus lens from the output from the extraction device, and when determining from the determination result that the focus lens is incapable of focusing, drives the focus lens to the stop position.
    • 本发明的目的是提供一种能够始终执行适当聚焦操作的自动聚焦方法和装置。 为了实现该目的,控制装置根据操作装置的操作来驱动聚焦透镜,并且存储聚焦透镜的停止位置。 当使用停止位置作为基准将聚焦透镜驱动在预定范围内时,控制装置将与提取装置的输出相关联地存储在聚焦透镜的位置上。 控制装置从提取装置的输出确定聚焦透镜的聚焦状态,并且当从确定结果确定聚焦透镜不能聚焦时,将聚焦透镜驱动到停止位置。
