Color monitor with improved digital convergence

摘要

A color video monitor is disclosed which includes improved digital convergence using a plurality of memory means in which vertical convergence correction values are stored, one memory each for red, green, blue and lateral blue convergence values. Interpolation means provide additional values between the points stored in memory such that a smooth transition between successive lines of the display is achieved. The correction values stored in the memories are generated by means of a high-order polynomial function.
