ABSTRACT:
In an apparatus for position transformation of input image data according to a transformation function to thereby generate image data at the position of each pixel of an output image, it is detected whether or not each position is located inside the boundary of the input image and, if so, the input image data for that position is transformed according to the transformation function, but if not, stored background image data is transformed according to the transformation function instead.
