ABSTRACT:
A method is disclosed for creating simultaneously viewable coarse and fine resolution displays, respectively presenting an "entire image" with coarse resolution of detail and a selected portion of that image in an enlarged view with fine resolution of detail. The method also provides for creation of cursor and crosshair images overlying the portion of the coarse display selected for enlarged viewing, and creation of an enlarged crosshair image overlying the enlarged display. The cursor image is in the form of a rectangle outlining the portion selected for "magnified" viewing in the fine display segment. The crosshairs provide relatively scaled position references on the coarse and fine views for enabling operators to accurately locate points within fine segments for specification to a computer system.
