    • An optical apparatus is disclosed which achieves high focusing accuracy and favorable responsiveness in AF control. The apparatus includes a signal generator which extracts signals in a plurality of frequency bands from an output from an image-pickup part and generates focus signals from the extracted signals, and a controller which performs focus control such that the focus signal approaches the highest value. The controller uses a first focus signal and a second focus signal in the focus control. The second focus signal is a synthesis signal formed by synthesizing a focus signal in a relatively high or the highest frequency band of the plurality of frequency bands and a focus signal in another frequency band and contains a component of the focus signal in the relatively high or highest frequency band at a higher ratio as compared with the first focus signal.
    • 公开了一种在AF控制中实现高聚焦精度和良好响应性的光学装置。 该装置包括:信号发生器,其从图像拾取部分的输出中提取多个频带中的信号,并从所提取的信号中产生聚焦信号;以及控制器,其执行聚焦控制使得聚焦信号接近最高值。 控制器在聚焦控制中使用第一聚焦信号和第二聚焦信号。 第二聚焦信号是通过合成多个频带的相对高或最高频带中的聚焦信号和另一个频带中的聚焦信号而形成的合成信号,并且包含相对高的聚焦信号的分量或 与第一聚焦信号相比,具有较高比率的最高频带。
