ABSTRACT:
An image processing apparatus for forming a modified image from an original image, in which addresses for the modified image are calculated, and corresponding addresses of the original image are calculated, both sets of calculations being performed in such a manner that a substantial amount of the data needed for the calculations is prestored in a look-up table or the like. In addition, the calculations are carried out in such a manner as to reduce the number of multiplications and divisions (versus additions) which must be performed, to increase calculation speed.
