PURPOSE:To attain the adjustment of an inside adjusting point once, by writing the same correcting amount the same as a convergence correcting amount at the inside also to the outermost circumference adjusting point, in adjusting the adjusting point at the immediate inside of the outermost circumference adjusting point of a screen. CONSTITUTION:When the same correcting amount is written in the inside adjusting point (b) and the outermost circumference adjusting point (a), since the same correcting amount is written also in a virtual adjusting point, the correcting amount of the virtual adjusting point overflows and the required correcting amount of the inside adjusting point is written in a 1-frame memory 5 without inversion. In adjusting the adjusting points in the screen other than the outermost circumference and the inside adjusting points, since only the address represented with a cursor counter 10 is applied to the memory 5 via a multiplexer 22 and an address multiplexer 11, the correcting amount is written in the memory 5 by the same operation as conventional examples. |
