1. An image processing device for correcting aberrations caused by a capturing lens for an image signal to which light passing through the capturing lens is electrically converted, the image processing device comprising:
correction vector calculation means for calculating a correction vector in accordance with coordinates of each pixel of each color component contained in the image signal on the basis of at least data on chromatic aberration and distortion aberration caused by the capturing lens;
conversion ratio calculation means for receiving at least the image signal, capturing conditions of the capturing lens, and the calculated correction vector, and for calculating a conversion ratio for scaling the color component in accordance with the coordinates of the pixel; and
resolution conversion means for scaling the color component in accordance with the coordinates of the pixel on the basis of the calculated conversion ratio.
