Abstract
The present invention provides 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 includes a correction vector calculation unit 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; a conversion ratio calculation unit for receiving at least the image signal, capturing conditions, and the correction vector, and for calculating a conversion ratio for scaling the color component in accordance with the coordinates of the pixel; and a resolution conversion unit for scaling the color component in accordance with the coordinates of the pixel on the basis of the conversion ratio.
