Abstract
A digital convergence correcting apparatus for a projection-type television set performs an interpolation calculation by employing an auxiliary calculating processor, to thereby perform faster convergence correction. In addition, an OSD block permitting user interface is unified with a test pattern generating block, thereby simplifying the overall hardware structure. A method for operating the digital convergence correcting apparatus is also described.
