Vertical/horizontal interpolation device and method in convergence system

A method for performing horizontal/vertical interpolation in a convergence system for a plurality of modes, comprising:

• (a) horizontal high order interpolating convergence adjustment data of a first set of prescribed positions using received horizontal/vertical convergence adjustment data regardless of a selected one of the plurality of modes;
• (b) horizontal first order interpolating convergence adjustment data of a second set of prescribed positions using the received horizontal/vertical convergence adjustment data regardless of the selected mode;
• (c) adjustment point processing convergence adjustment data of a third set of prescribed positions using the received horizontal/vertical convergence adjustment data regardless of the selected mode;
• and
• (d) vertical interpolating the horizontally interpolated data.

A method for performing horizontal/vertical interpolation in a convergence system, comprising:

• (a) horizontal high order interpolating step for making horizontal high order interpolations of convergence adjustment data of first prescribed positions of received horizontal/vertical convergence adjustment data regardless of modes;
• (b) a first horizontal first order interpolating step for making horizontal first order interpolations of convergence adjustment data of second prescribed positions of the received horizontal/vertical convergence adjustment data regardless of modes;
• (c) a first adjustment point processing step for subjecting convergence adjustment data of third prescribed positions to adjustment point data processing of the received horizontal/vertical convergence adjustment data regardless of modes, wherein the first, second and third prescribed positions constitute data for a horizontal row, wherein the data are used to prepare a correction waveform;
• (d) a second adjustment point processing step for overwriting a subset of the second prescribed positions using adjustment point processing in a first mode and for overwriting a subset of the first prescribed positions using adjustment point processing in a second mode;
