An electronic camera includes an imager which outputs an object scene image in a designated cycle. The first changer changes a distance from a focus lens to the imaging surface. The first adjustor adjusts the designated cycle to a length corresponding to an illuminance of the object scene in association with a process of the first changer. The first specifier specifies a distance range including a focal point in parallel with the process of the first changer. The second changer changes the distance from the focus lens to the imaging surface in the distance range specified by the first specifier. The second adjustor adjusts the designated cycle to a length corresponding to a contrast of the object scene in association with a process of the second changer. The second specifier specifies the distance corresponding to the focal point in parallel with the process of the second changer.
