ABSTRACT:
An apparatus and method for controlling a convergence of a projection television includes a pattern generator which generates R, G, and B video patterns used for controlling the convergence and then outputs the R, G, and B video patterns to a display, and a controller which compares position coordinates and luminance levels of the R, G, and B video patterns with position coordinates and luminance levels of reference R, G, and B video patterns to adjust the luminance levels of the R, G, and B video patterns to the luminance levels of the reference R, G, and B video patterns.
