ABSTRACT:
Image processing apparatus for performing transformation from a source image to a target image along a number of consecutive lines parallel to a coordinate axis of the source image of said target image. The apparatus includes a point generator that sequentially determines target image points near a desired hyperbola, and outputs a number of lattice points as an approximation of the hyperbola. The apparatus maps between coordinates of pixels of the source image and coordinates of pixels of the target image based on the output of the points generator; and determines pixel values of the target image based on results of the mapping and the values of source image pixels.
