ABSTRACT:
Apparatus and method of generating variable size, point-display type characters. Each character is defined through a matrix comprising a plurality of identical block elements. One of a predetermined number of geometric patterns forming a section of each character is disposed within each block element. A distinct binary index code is assigned to each geometric pattern on a row-by-row, column-by-column basis of each character matrix for the entire character set to be displayed and stored in a first memory. A binary code defining the sequence of binary states of the points in the point display of each geometric pattern is assigned to each geometric pattern on a line-by-line basis for each block element of the character matrix. The first set of binary codes are selected on a row-by-row, column-by-column basis for the character matrix of the selected character. A second set of binary codes are generated in response to the selected first binary codes, with the second binary codes corresponding to the sequence of binary states of the points defining the point matrix on a line-by-line basis for each block element of the selected character matrix. A binary sequence of signals is generated in response to the second binary codes which are used to generate each character point-by-point.
