Abstract

Abstract The present invention provides an image processing system capable of enlarging and reducing operations by means of an interpolation circuits in which a interpolation data memory for producing an image data interpolating between plural sets of adjacent image information and a selection signal memory for outputting a selection signals to the interpolation data memory in accordance with the designated magnification. The interpolation data memory has a plurality of data tables having different conversion characteristics with each others and the data table can be selected in accordance with the property of the original image.
