Abstract
Alphanumeric characters are stored in compressed form by creating a character list of information describing each character. The character is divided into rows and columns. To reconstruct the character, a position register is provided to accommodate successive positional values in a column where a transition from white/black (or vice versa) occurs. A decoder circuit, which has a number of outputs corresponding to the number of positional values possible, is coupled to the position register and provides an output associated with each of the transition values. The decoder circuit is followed by control means which is operable in response to the energized outputs of the decoder circuit to generate control signals which energize a utilization device to reconstruct continuous black areas in a column extending from transition value to transition value.
