Abstract:
1. A camera comprising: an image-capturing element that captures a subject image through a photographic lens; an evaluation value calculation unit that calculates a focus evaluation value based upon an image-capturing signal output from the image-capturing element; a focusing operation unit that performs a focusing operation at the photographic lens based upon the focus evaluation value; a decision-making unit that makes a decision as to whether or not a focus evaluation value calculated by the evaluation value calculation unit manifests a change by an extent larger than a predetermined value relative to a focus evaluation value calculated at a focusing operation end after a predetermined length of time has elapsed following the focusing operation end; a restart unit that enables the focusing operation unit in a focusing operation when the decision-making unit decides that the change by the extent larger than the predetermined value has occurred; and a time adjustment unit that changes the predetermined length of time.
