An image processing device, an image processing method, and an image processing program by which deformation such as distortion caused by an imaging optical system can be corrected with high precision without increase in memory capacity and processing time. The image processing device comprises a vertex sampling coordinate computing section (30) for computing a sampling position on an input image by a high-order expression so as to cancel out distortion at the position of a predetermined pixel of an output image, a sampling coordinate interpolation computing section (31) for interpolating the sampling position on the input image, at the position of a pixel other than the position of the predetermined pixel of the output image, from a sampling position of a predetermined output pixel located near the pixel, and a sampling unit (32) for sampling a pixel value of the input image at the sampling position computed via the vertex sampling coordinate computing section (30) and the sampling coordinate interpolation computing section (31). |
