Abstract
An image processing system for altering the size of an image represented by a plurality of input video signals including a controller for producing a scale factor and a scale factor valid signal. The controller also includes a padder which is used to increase the accuracy of the scale factor during the operation of the controller. The signals generated by the controller are passed to an interpolator suitable for producing an output signal as a function of one or more of the input video signals in response to the scale factor and scale factor valid signal.
