Abstract:
A focus adjustment device obtains a correction value for correcting a result of autofocus, from aberration information regarding at least one of an astigmatism, a chromatic aberration, and a spherical aberration of an imaging optical system, and focus detection information regarding the autofocus. The focus adjustment device then controls a position of a focusing lens that the imaging optical system has, based on a result of the autofocus corrected using the correction value. By correcting the result of the autofocus while considering at least a focus condition of a photographic image, a focus detection error caused by an aberration of the optical system can be accurately corrected.

Claim (Index 8):
A focus adjustment method for adjusting an autofocus position of a focusing lens obtained by executing autofocus by at least one of a phase-difference detection method and a contrast detection method, the method comprising:\n obtaining a correction value based on an evaluation band of a focus detection signal used in executing the autofocus, an evaluation band of an image signal to be captured, and information on aberrations of the imaging optical system; correcting the focus detection result by using the correction value; and controlling a position of the focusing lens that an imaging optical system has, based on the result of the autofocus corrected using the correction value, wherein the information on aberrations comprises (i) first band information that corresponds to at least one of astigmatism, chromatic aberration, and spherical aberration of the imaging optical system and (ii) aberration information corresponding to the first band information, and wherein the obtaining (i) calculates, based on the first band information and the aberration information corresponding to the first band information, aberration information corresponding to a band that is within a second band except the first band, and (ii) obtains the correction value based on the evaluation band of a focus detection signal used in executing the autofocus, the evaluation band of an image signal to be captured, and the calculated aberration information.
