Patent 7623153 was granted and assigned to Sanyo Electric Co Ltd on November, 2009 by the United States Patent and Trademark Office.
Provided is an unintentional hand movement canceling device, comprising: swing detecting means detecting a swing of an image; and a correction quantity generating means generating a correction quantity to calculate a correction position based on a swing quantity detected by the swing detection means, a damping coefficient of a swing quantity for controlling a characteristic of a non-corrected residue percent at a swing frequency and a damping center for controlling a centering velocity at which a correction position is caused to move to an initial position before correction, the correction quantity having a variable characteristic of a non-corrected residue percent at a frequency of the swing and a variable centering velocity at which a correction position is caused to move to an initial position before correction, wherein the correction quantity generating means includes means updating the damping center based on a preset damping coefficient of the damping center.
