Abstract:
An image correcting device includes an image input section, an image storage section, a correction table storage section, a geometry correcting section for geometrically correcting an input image stored in the image storage section, based on a correction table, and an image output section for output of the input image corrected by the geometry correcting section, wherein the correction table is created by calculating longitudes and latitudes that correspond to respective pixel positions on an output image that becomes the corrected image; calculating corrected latitudes through correction of the latitudes, based on the longitudes and the latitudes; calculating light directions in a subject space, the light directions corresponding to the longitudes and the corrected latitudes; and calculating positions on the input image as resampling positions, the positions corresponding to the respective light directions; and associating the resampling positions with the pixel positions on the output image.
