Imaging device having motion detector and in-focus position estimating unit, and imaging method

摘要

An imaging device is configured to include an imaging lens, an imaging unit which acquires image data based on an optical image of a subject received via the imaging lens, a motion detector which detects a motion of the subject based on image data sequentially obtained from the imaging unit, a focus detector which calculates focus position data based on the image data obtained from the imaging lens when the motion detector detects a motion of the subject, and an in-focus position estimating unit which estimates an in-focus position based on the calculated focus position data.

1. An imaging device comprising:
an imaging lens; an imaging unit which acquires image data based on an optical image of a subject received via the imaging lens; a motion detector which detects motion of the subject from image data sequentially acquired from the imaging unit; a focus detector which calculates focus position data based on the image data acquired via the imaging lens which is driven in a second drive range smaller than a first drive range in which the imaging lens is movable upon a press of a release operation member, in response to detection of motion of the subject by the motion detector; and an in-focus position estimating unit which estimates an in-focus position based on the calculated focus position data, and wherein, when the in-focus position is not present in the second drive range, and the release operation member is pressed, an end position of the second drive range adjacent to the estimated in-focus position is set to a drive start position of the imaging lens.
