Patent ID: 7633525

Claim:
An unintentional hand movement canceling device, comprising: swing detecting means detecting a swing of an image; state discriminating means discriminating a swing state due to an intentional camera motion by a cameraman or a camerawomen from an unintentional hand movement state; a first correction quantity generating means, when it is determined by the state discriminating mean that a current state is an unintentional hand movement state, 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 swing frequency and a variable centering velocity at which a correction position is caused to move to an initial position before correction, a second correction quantity generating means, when it is determined that a current state is an intentional camera motion by a cameraman or a camerawomen, adopting a correction quantity of the immediately proceeding frame as a correction quantity for calculating a correction position; and means, when it is detected by the state discriminating means that an intentional camera motion by a cameraman or a camerawomen has changed to an unintentional hand movement state, setting a damping center to a correction position corresponding to the correction quantity at that time, wherein the first correction quantity generating means includes means to update the damping center based on a preset damping coefficient of the damping center.
