Abstract

PURPOSE: The mth picture element signal in the lth column is predicted by means of the difference between "the sum of the values of decoded picture elements on the (m-1)th of the lth column and on the mth of the (l-2)th column and "the decoded value of the (m-1)th of the (l-2)the column,"thereby obtaining a simple but highly accurate prediction system.
