    • A focus condition detecting device which generated first and second light intensity distribution signals representing light intensity distributions on first and second arrays arranged to receive lights having passed through different areas of the exit pupil of an objective lens is arranged so as to divide the first light intensity distribution signal into a plurality of blocks. Each of the portions of the first light intensity distribution signal belonging to the respective blocks is shifted relative to the second light intensity distribution signal by sequentially changing an amount of shift, so that correlations therebetween are calculated for finding the amount of shift providing the highest correlation. In accordance with the amount of shift found to provide the highest correlation through the correlation calculation with use of the portion of the first light intensity distribution signal belonging to one of the blocks, the shift range for the succeeding correlation calculation with use of the portion of the first light intensity distribution signal belonging to another one of the blocks is restricted to shorten the period of time required for the succeeding correlation calculation.

    • A camera with a multi-zone focus detecting device has an objective lens mounted on a camera. An image formed by the objective lens is divided into a plurality of zones. In each zone, a focusing condition is detected based on the image formed by the objective lens so as to produce a plurality of focusing condition data. Based on the result of the focusing conditions, one zone is selected. Furthermore, a light which has passed through the objective lens is measured separately in each zone so as to produce a plurality of measured light data. Based on a focusing condition data obtained from the selected zone, the objective lens is driven to an infocus condition. When the objective lens is driven to the infocus condition, a measured light data obtained from the selected zone is used for calculating exposure data with which the exposure is controlled.
    • 具有多区域焦点检测装置的相机具有安装在相机上的物镜。 由物镜形成的图像被分成多个区域。 在每个区域中,基于由物镜形成的图像来检测聚焦条件,以产生多个聚焦条件数据。 根据聚焦条件的结果,选择一个区域。 此外,在每个区域分别测量已经通过物镜的光,以便产生多个测量的光数据。 基于从所选择的区域获得的聚焦条件数据,物镜被驱动到聚焦条件。 当物镜被驱动到聚焦条件时,从所选择的区域获得的测量光数据被用于计算曝光被控制的曝光数据。
