<P>PROBLEM TO BE SOLVED: To provide an image blur correction device that provides a vibration-proof effect required according to a situation and, at the same time, is able to restrain a phenomenon in which a vibration-proof lens stays at the maximum driven position and also able to restrain image quality degradation resulting from deviation of a vibration-proof lens from the center of an optical axis. <P>SOLUTION: In the case where a shutter speed when photographing is carried out with an optical instrument using the image blur correction device is higher than a predetermined value and is lower than a second predetermined value that is higher than the first predetermined value, a vibration-proof drive part 104 increases the movable range of the vibration-proof lens compared to the case where the shutter sipped is lower than the first predetermined value or higher than the second predetermined value. <P>COPYRIGHT: (C)2013,JPO&INPIT |
