An image-capturing apparatus includes a focus lens that forms an object image of the object, an image sensor that produces image data by capturing the object image, and a controller that controls the focus lens. The focus lens has a focal position. The controller is operable to detect a change of a distance from the image-capturing apparatus to the object during a first exposure period based on image data produced by capturing the object image with the image sensor during the first exposure period. The controller is operable to determine, based on the detected change in the distance, a control amount which controls a moving velocity at which the focal position moves during a second exposure period after the first exposure period. The controller is operable to move the focal position at a moving velocity corresponding to the determined control amount, and cause the image sensor to capture the object image during the second exposure period. |

1. An image-capturing apparatus that captures an image of an object, the image-capturing apparatus comprising:
a focus lens that forms an object image of the object, the focus lens having a focal position; an image sensor that produces image data by capturing the object image; and a controller that controls the focus lens, wherein the controller is operable to
detect a change of a distance from the image-capturing apparatus to the object during a first exposure period based on image data produced by capturing the object image with the image sensor during the first exposure period,determine, based on the detected change of the distance, a control amount which controls a moving velocity at which the focal position moves during a second exposure period after the first exposure period, andmove the focal position at a moving velocity corresponding to the determined control amount, and cause the image sensor to capture the object image during the second exposure period. |
