Abstract
An image correction device trims an image, which has been captured by a camera provided in a moving object, in accordance with a predetermined image frame to generate a corrected image that is enclosed by the predetermined image frame, and then outputs the corrected image as an output image. Even when there is an error between an actual camera position in which the camera is actually positioned and a scheduled camera position in which the camera is scheduled to be positioned, the image correction device (i) decomposes the error into a first component that extends along an imaging direction of the camera and a second component that extends along a plane orthogonal to the imaging direction, (ii) shifts the image frame in accordance with the first component, and (iii) enlarges or shrinks a size of the image frame in accordance with the second component.
