Optical device, control method therefor, and storage medium storing control program therefor

摘要

An optical device that is capable of reducing eccentric aberration while reducing image blur. A first shake correction unit corrects image blur optically based on a shake amount that is detected by a shake detection unit. A second shake correction unit corrects image blur optically based on a shake amount that is detected by the shake detection unit. The second shake correction unit has a different image blur correction effect from the first shake correction unit. The optical device has a mode in which shake correction is performed using the first shake correction unit without using the second shake correction unit.

主权项

1. An optical device comprising:
a shake detection unit; a face detection unit; a first shake correction unit configured to correct image blur optically based on a shake amount that is detected by said shake detection unit; and a second shake correction unit configured to correct image blur optically based on a shake amount that is detected by said shake detection unit, wherein the image blur correction effect of said second shake correction unit is higher than that of said first shake correction unit, and image distortion amount with resect to a correction angle of said first shake correction unit is smaller than that of said second shake correction unit, wherein the image blur is optically corrected using said first shake correction unit when reliability of a face detection result by said face detection unit is not lower than a threshold, and wherein the image blur is optically corrected using said second shake correction unit when the reliability of the face detection result by said face detection unit is lower than the threshold.
