Abstract
An apparatus and method for graphic conversion for electronic data processing wherein an image is converted to an electrical analog signal which is converted to digital data representing discrete segments of the image containing color value data. The digital data is converted to an analog signal by a curve fitting technique responsive to adjacent discrete segments and the analog signal drives a visual display means which recreates the original image. Means are provided to store and/or modify the digital data to effect predetermined changes in the recreated images.
