PROBLEM TO BE SOLVED: To perform focus adjustment in reference to a focus status displayed based on misalignment of images picked up while moving a diaphragm in a direction perpendicular to an optical axis. SOLUTION: An aperture diaphragm is provided, which can be shifted right and left on an object light path. An extent of out-of-focus is obtained by detecting misalignment between the image picked up when the aperture diaphragm is shifted right, and that picked up when it is shifted left. A split image is created based on the image picked up when the aperture diaphragm is shifted right and the image picked up when the aperture diaphragm is shifted left, and displayed on a monitor. An operation quantity of a focus ring is detected by a ring sensor 7a, a motion quantity of the split image is calculated based on the extent of out-of-focus, the operation quantity of the focus ring, and the split image moving relative to the focusing operation is displayed.
