| 1. An imaging apparatus comprising:
a solid-state imaging unit configured to receive an image of a subject formed through a lens unit configured to perform focusing
and to output an image signal composed of a plurality of continuous images;
a detecting unit configured to detect a motion vector of each of the plurality of images;
a combining unit configured to combine the plurality of images in accordance with each motion vector detected by the detecting
unit to produce a composite image;
an extracting unit capable of extracting a first signal corresponding to a focusing state of the lens unit from the combined
image, and a second signal corresponding to a focusing state of the lens unit with respect to a subject from the plurality
of images before being combined; and
a focus controlling unit configured to control the lens unit in accordance with the extracted first signal and the second
signal to perform focusing.
