1. An image stabilization device comprising:
- a motion sensor that detects motion data of the image stabilization device;
an image data display that displays image data; and
a computer configured to;
calculate a shake coefficient indicating intensity of shaking based on time-series motion data detected by the motion sensor, the shake coefficient being an amplitude value obtained in a predetermined frequency domain above a predetermined frequency threshold among the time-series motion data;
perform control of the image data display, in a case that the shake coefficient is obtained in the predetermined frequency domain above the predetermined frequency threshold, and the shake coefficient calculated by the computer becomes less than a predetermined first threshold, to move an entire area of the image data in a direction of cancelling the shaking; and
end the control to move the entire area of the image data in the direction of cancelling the shaking in a case that the shake coefficient calculated by the computer becomes less than a predetermined second threshold that is less than the predetermined first threshold.
