ABSTRACT:
Disclosed is a projection image display apparatus, specified in a convergence adjusting apparatus employing a spline interpolation scheme. In the projection image display apparatus, the convergence adjusting apparatus includes controller for selecting sections arranged between seeds of convergence adjustment among a plurality of horizontal and vertical lines and for interpolating first through fourth position coefficients of control seeds assigned to the selected section, a position coordinate generator for performing operations on the number of the horizontal lines and its squared and cubed values by counting horizontal synchronization signals and generating the same, a multiplier for multiplying the horizontal line number output from the position coordinate generator and its squared and cubed values by each of the first through fourth position coefficients output from the controller, and an adder for summing the first position coefficient output from the controller and an output of the multiplier to generate values of the sections interpolated.
