发明名称 Image sensing apparatus providing driving direction of focus lens for attaining in-focus state and control method therefor
摘要 In an image sensing apparatus including an image sensing unit with an image sensor and an EVF, first image signals obtained every preset number of frames, of image signals output from the image sensing unit are displayed on the EVF, focus evaluation values indicating a focus state of an image are obtained from second image signals obtained in frames other than the frames for the first image signals of the image signals output from the image sensing unit, a direction of driving a focus lens for an in-focus state is determined on the basis of the obtained focus evaluation values, and the determined driving direction is displayed on the EVF. Further, the focus lens is moved for image sensing in the frames for the second image signals to carry out image sensing of the subject at different focus lens positions for each frame.
