Abstract

PURPOSE:To quickly and accurately perform convergence adjustments by displaying information on the completion of correction of each adjusting point. CONSTITUTION:Dot patterns projected on a screen 32 represent adjusting points on which the convergence correction is performed. A television camera 30 detects convergence lag and, by its detecting signal, convergence amounts are automatically written in the memory of a digital convergence section 24. When corrections of an adjusting point are completed, a coincidence detecting signal is added to a pattern generating section 16 through a completion displaying counter 28 from a convergence coincidence detecting section 31, and the completion of the correction of the adjusting point is displayed on the screen 32. Corrections of each adjusting point are performed by repeating this procedure. Since adjusting points on which corrections are completed become clear, convergence adjustment is performed quickly and accurately.
