Abstract
An image blurring correction apparatus includes: an optical system that forms a subject image on an image formation plane; an acceleration sensor that detects an acceleration of an apparatus that has the image formation plane; a first calculation circuit that calculates a first state quantity by using the acceleration; a second calculation circuit that calculates, as a second state quantity, an estimate value obtained by estimating a true value of the first state quantity by using the first state quantity and a model; and a third calculation circuit that calculates an amount of image blurring on the image formation plane by using the second state quantity.
