An imaging device includes a lens and a circuit configured to control the lens to move in a first direction along an optical axis of the lens, control capture of a plurality of first images via the lens when the lens is positioned at a plurality of first positions, respectively, control the lens to move in a second direction opposite to the first direction, control capture of one or more second images via the lens when the lens is positioned at one or more second positions, respectively, and determine a focus position based on one or more of a plurality of first evaluation values calculated from the plurality of first images and one or more second evaluation values calculated from the one or more second images. Each of the plurality of first evaluation values and the one or more second evaluation values indicates a corresponding focus state.
