  • Patent number: 4168489
    Abstract: An electronic system for reducing a full page of text to fit onto the visual display screen of a partial page display word processing device for purposes of reviewing the format and page layout of the text. The text is not always legible in this condensed mode, which is switch selectable by the operator, but while in this mode the text may be edited and manipulated in the normal manner provided by the controls of the word processing device. The system utilizes both electronic digital logic and analog circuits to condense the size of an entire page of text by approximately a factor of three. The digital logic selects and displays only five of the normal fourteen horizontal lines of dots comprising each row of characters within the page of text to be reduced, thus condensing the characters vertically.
