PROBLEM TO BE SOLVED: To correct camera shake due to translational motion by a simple configuration.SOLUTION: An imaging device includes: a first acceleration detecting section 127 detecting an acceleration in each axial direction acting on the imaging device as a first acceleration; a second acceleration detecting section 129 detecting a second acceleration; and an angular velocity detecting section 128 detecting an angular velocity in each direction around a first axis and a second axis as a first angular velocity. The imaging device also includes: an angular velocity calculating section calculating an angular velocity around a third axis as a second angular velocity on the basis of the first acceleration, the second acceleration and a predetermined distance; an initial posture computing section 81 calculating an initial posture value of the imaging device; a posture computing section 82 calculating a posture change amount from the initial posture value; a coordinate transform matrix computing section 83 calculating a coordinate transform matrix; and a translational camera shake correction amount computing section 87 calculating a translational camera shake correction amount that is a correction amount for camera shake caused by translational motion, on the basis of the first acceleration removed of a second gravitational acceleration. |
