ABSTRACT:
A display apparatus capable of displaying, by use of an ordinary television set function, character/figure information having a higher display density than standard chemistry character figure information. The apparatus includes a first reducing device for reducing into a pixel a partition having vertical and horizontal lengths respectively twice the vertical and horizontal lengths of a smallest pixel zone associated with a dot pattern signal, character generators and a second reducing device for producing a reduced character pattern associated with character codes in a received signal, and a third reducing device for reducing into a block a partition having vertical and horizontal lengths respectively twice the vertical and horizontal lengths of an attribute data specification block specifying a character/figure display attribute in the signal. The reduced character/figure image signals of the entire screen information obtained through the constituent components above are displayed via a display processing circuit. In a display area appropriately selected by the user, a partial image can be displayed in a specified display density.
