Abstract
An information processing apparatus is provided and includes: a first storage section to store coordinates of luminance change points in a calibration pattern having a luminance distribution in two axis directions orthogonal to each other; a generation section to generate standard pattern information on a luminance distribution of a calibration image; a determination section to determine coordinates of a luminance change point of the calibration image, as coordinates of a correction luminance change point; a first calculation section to calculate a difference between the stored coordinates of the luminance change points and the coordinates of the correction luminance change points, as a distortion vector field; a second calculation section to calculate a component obtained by removing a translation component and a rotational component from the distortion vector field, as a correction vector field; and a correction section to correct an image captured by the imaging section by using the calculated correction vector field.
