<p>Image processing apparatus is disclosed for performing projective transformation from a source image to a target image along a plurality of consecutive lines parallel to one of the coordinate axes of the source image or the target image, the image processing apparatus comprising;a hyperbola generator that sequentially examines rectangular lattice points near a desired hyperbola sequentially along the hyperbola, and outputs a chain of the determined lattice points as an approximate curve of the hyperbola, mapping means that determines a mapping between the coordinates of the pixels of the source image and coordinates of the pixels of the target image based on the output of the hyperbola generator, and means that determines the values of the pixels of the target image based on the mapping and the values of pixels of the source image.</p> |
