<p>An image capture device according to an aspect of the present invention comprises: an image capture element; a lens optical assembly including a focus lens; a drive unit which drives either the image capture element or the focus lens; a displacement control unit which, based on a prescribed displacement pattern, controls the displacement of either the driven image capture element or the driven focus lens; an iris, disposed in the lens optical assembly, and provided with an aperture of variable size; an aperture control unit which controls the size of the iris aperture; a synchronization unit which, based on the exposure timing, controls the displacement control unit and the aperture control unit; and an image capture parameter establishment unit which establishes the exposure time, the size of the iris aperture, and the displacement pattern. The prescribed displacement pattern includes a first-type displacement pattern and a second-type displacement pattern in which either the image capture element or the focus lens is displaced at different ranges between a first focus location and a second focus location in an image capture scene. The first-type displacement pattern and the second-type displacement pattern are alternately repeated. Based on the timing from the synchronization unit, the aperture control unit controls the iris to have a first aperture and a second aperture with a different size from that of the first aperture in the first-type displacement pattern and the second-type displacement pattern.</p> |
