Precision automatic scrolling for an image display system

A method for processing an image for display on a video screen comprising the steps of:

• selecting a first point within a component of the image on said video screen, said component having a first portion within a first display frame currently visible on said video screen and a second portion which may not be currently visible in said first display frame;
• selecting a vector function to determine a second point on said image, said second point being within said second portion of said image;
• responsive to said selecting a vector function, processing first coordinates indicative of said first point and definitional characteristics of said component so as to determine second coordinates of said second point on said component;
• and
• responsive to said processing, displaying in a second display frame an area of said component including said second point.

A system for processing an image displayed on a video screen comprising:

• means for selecting a first point within a component of the image on said video screen, said component may or may not have a portion currently visible on said video screen;
• using vector format means for comparing first coordinates indicative of said first point with a definitional characteristics of said component;
• means, coupled to said vector format means for comparing, for determining second coordinates of a second point on said component furthest from said first point;
• and
• means, connected to receive said second coordinates from said means for determining, for displaying an area of said component centered around said second point.
