Patent ID: 8736690

Claim:
An image pickup apparatus having an imaging device disposed on an imaging optical axis, an imaging optical system for forming an image of a subject on said imaging device, and a movable section that causes an internal acceleration during operation thereof, said image pickup apparatus comprising: an angular velocity detector for detecting an angular velocity in accordance with rotation of said image pickup apparatus; an acceleration detector for detecting a first translational acceleration in accordance with translational movement of said image pickup apparatus; a translational acceleration calculator for calculating a second translational acceleration caused by an external factor on said image pickup apparatus by subtracting said internal acceleration from said first translational acceleration; a translational velocity calculator for calculating a translational velocity by integrating said second translational acceleration; a rotation radius calculator for calculating a rotation radius based on said angular velocity and said translational velocity; a rotation angle calculator for calculating a rotation angle by integrating said angular velocity; a shake amount calculator for calculating a camera shake amount containing an angle camera shake and an shift camera shake based on said rotation angle and said rotation radius, said angle camera shake occurring due to rotation of said imaging optical axis, and said shift camera shake occurring due to parallel shifting of said imaging optical axis; and a driver for moving said imaging optical system as a whole or an optical component constituting said imaging optical system, or moving said imaging device, in a direction for canceling said camera shake amount, so as to correct said angle camera shake and said shift camera shake.
