Abstract

PURPOSE:To make adjustment in a short time, independently of skillness of an adjusting person, by detecting a shift of a convergence adjusting pattern pictured on a screen of a color TV receiver through the use of a TV camera storing the amount of directional movement corresponding to an address signal for the adjusting point. CONSTITUTION:A deflection circuit 25 scans electron beam via a deflection yoke 22 in synchronizing with an incoming synchronizing signal. A video circuit 7 pictures dot patterns from a dot generator on a screen 19 at convergence adjustment via a projection type reception tube 20. A part of the adjusting pattern pictured on a screen 29 is extended and detected at an image sensor 26, where an angle position shift amount corresponding to each adjusting point of a TV camera head 27 corresponding to the write-in address from an input section 31 is stored in advance. With the constitution like this, when the address for the adjusting point is designated to an input section 31, the convergence of the designated adjusting point is automatically adjusted with good reproducibility via a digital convergence section 24.
