Patent ID: 7962024

Claim:
A blur correcting device comprising: a shake detecting unit configured to detect a shake and output a detection signal indicating a result of the detection; a drive unit configured to displace a relative positional relationship between a lens unit and an image pickup element relative to an optical axis such that a position of an optical image formed on an image pickup surface of the image pickup element is displaced on the image pickup surface; and a control unit configured to control the drive unit to displace the relative positional relationship between the lens unit and the image pickup element within a displacement range in accordance with the detection signal, and thereby correct a blur of the optical image on the image pickup surface caused by the shake detected by the shake detecting unit, wherein, the control unit is configured to limit said displacement range to a first range narrower than a maximum displacement range in accordance with a zoom position, the control unit is configured to limit said displacement range to said first range when the amount of shake indicated by the detection signal is smaller than a predetermined level, and the control unit is configured to limit said displacement range to a second range when the amount of shake indicated by the detection signal is larger than said predetermined level, wherein said second range is increased relative to said first range.
