Abstract:
1. An image correction device for correcting at least one image that has been captured by a camera provided in a moving object, the image correction device comprising: an image acquisition unit operable to acquire an image captured by a camera; a difference acquisition unit operable to acquire positional difference information indicating a difference between (i) a scheduled camera position in which the camera is scheduled to be positioned at a scheduled time to capture the image and (ii) an actual camera position in which the camera is positioned at the scheduled time; a determination unit operable to determine an output image frame, by correcting a standard image frame in accordance with the acquired positional difference information; a corrected image output unit operable to (i) trim the captured image in accordance with the determined output image frame to generate a corrected image that is enclosed by the determined output image frame, and (ii) output the corrected image; a camera information acquisition unit operable to acquire imaging direction information indicating at least one of (i) an actual imaging direction in a range of an optical axis of the camera along which the camera captures the image from the actual camera position, and (ii) a scheduled imaging direction in a range of an optical axis of the camera along which the camera is scheduled to perform an image capturing from the scheduled camera position, wherein the standard image frame is located within the captured image in a position that is determined by a first reference point, and the determination unit comprises: a decomposition subunit operable to, in accordance with the acquired imaging direction information, decompose the difference indicated by the positional difference information into (i) a first component that extends along the imaging direction indicated by the imaging direction information, and (ii) a second component that extends along a plane orthogonal to the imaging direction; a size calculation subunit operable to determine a size of the output image frame, by correcting a size of the standard image frame in accordance with the first component; and a point calculation subunit operable to determine a second reference point that determines a position in which the output image frame is located within the captured image, by shifting the first reference point of the standard image frame in accordance with the second component.
