A camera includes: an image-capturing element that captures a subject
image through a photographic lens having a focusing lens; an evaluation
value calculation unit that calculates focus evaluation values at a
plurality of lens positions assumed by the focusing lens based upon an
image-capturing signal output by the image-capturing element; a weighting
unit that weights the focus evaluation values calculated by the
evaluation value calculation unit in correspondence to the lens positions
of the focusing lens assumed when the focus evaluation values are
calculated respectively; and a focusing operation unit that performs a
focusing operation for the photographic lens based upon the weighted
focus evaluation values.
