1. An image processing device comprising: at least one processor configured to: acquire information on a first frame image, a second frame image and a third frame image that constitute a moving image obtained through capturing by an imaging unit, the second frame image being between the first frame image and the third frame image; correct a second imaging direction of the second frame image based on at least one of a first imaging direction of the first frame image and a third imaging direction of the third frame image to reduce differences between the first imaging direction, the second imaging direction and the third imaging direction; and send the second frame image having the corrected second imaging direction to a display unit.
