A GRAY SCALE INTERPOLATION TECHNIQUE ABSTRACT OF THE DISCLOSURE Expanded gray scale information is recovered from quantized video input data in a raster scanned imaging system by utilizing an interpolation process to predict a gray scale value for each element of output data from the quantized levels of a m x n matrix of input data elements. The prediction matrix for each output data element includes the spatially corresponding input data element, together with vertically and horizontally input data elements.
