    • An apparatus for detecting focus conditions of an imaging optical system is disclosed. The apparatus comprises a light flux dividing means having a plurality of light flux dividing elements arranged at a predetermined focal plane or near a plane conjugated therewith, a photoelectric conversion means having a plurality of light receiving elements arranged to receive light fluxes divided by respective light flux dividing elements in line therewith and means for detecting focus conditions of the imaging optical system based on the outputs of the light receiving elements. The photoelectronic conversion means is so arranged that the cross-section of light fluxes incident upon respective light receiving elements at the exit pupil of the imaging optical system includes regions which are not overlapped with each other.

    • A focus indicator for a TV camera includes a first image sensor and a video processor which convert an object image to a first video signal, an optical system for exit pupil dividing part of the object image to prepare a split image, and a second image sensor for converting the split image to a second video signal. A composing circuit generates a composite video signal from the first and second video signals in such a way as to include the split image component, and a viewfinder displays an image including the split image. A user of the TV camera thus can perform focusing by observing the split image in the viewfinder.
    • 电视摄像机的聚焦指示器包括第一图像传感器和将对象图像转换为第一视频信号的视频处理器,用于将对象图像的一部分进行出射光瞳分割以准备分割图像的光学系统,以及第二图像传感器 用于将分割图像转换为第二视频信号。 合成电路以包括分割图像分量的方式从第一和第二视频信号生成复合视频信号,并且取景器显示包括分割图像的图像。 因此,电视摄像机的用户可以通过观察取景器中的分割图像来进行聚焦。
