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; send the second frame image having the corrected second imaging direction to a display unit; and control the display unit to display a route on a map, wherein the route corresponds to frame images that constitute the moving image.
