Abstract
An image processing apparatus processes image data configured of pixels disposed in grid form. The apparatus includes an obtaining unit that obtains distortion characteristics indicating characteristics of distortion in a target contained in original image data obtained by capturing an image of the target, and a correction unit that, using a sampling function, interpolates a pixel of interest in the original image data, based on pixels of the original image data present in a reference region in the periphery of the location of the pixel of interest. The correction unit changes the range of the reference region, the frequency characteristics of the sampling function, or both in accordance with the distortion characteristics.
