SHAKE AMOUNT DETECTION DEVICE, IMAGING DEVICE AND SHAKE AMOUNT DETECTION METHOD

摘要

[Problem] To detect an accurate movement amount even when a shock is generated by a movable part such as a shutter. [Solution] A shake amount detection device according to the present invention is characterized by performing: a rotation radius calculation process for calculating a rotation radius from a speed change obtained by time-integrating an acceleration and an angular velocity; a speed calculation process for calculating a speed on the basis of an angular velocity and a rotation radius calculated before the start of exposure during a prescribed time period from the start of exposure, and calculating a speed by cumulatively adding an acceleration to a speed calculated during the prescribed time period after the prescribed time has passed; and a movement amount calculation process for calculating a movement amount by time-integrating the speed calculated by the speed calculation process.
