ABSTRACT:
A frame of information to be displayed in the form of a row and column matrix of display elements is created from a corresponding group of data cells stored functionally in the form of a row and column matrix where the number of rows and columns in the stored matrix is less than the number of rows and columns in the displayed matrix. The value of each display element is determined by obtaining the average of the values of the data cells with which the display elements immediately adjacent the display element, the value of which is to be determined, correspond summed with n times the value of the data cell corresponding to the display element, the value of which is to be determined, where n is an integer greater than one.
