Abstract
A camera includes: 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 predetermined length of time has elapsed following an end of the focusing operation; a restart unit that engages the focusing operation unit in a focusing operation if the decision-making unit decides that the predetermined length of time has elapsed; and a time adjustment unit that changes the predetermined length of time.
