Abstract
Double line sequential scanning is performed on a display apparatus which displays, for example, a television signal and a character and graphics signal. When only a television signal is to be displayed, priority is given to the resolution of the image. When a character an graphics signal is to be displayed superimposed on the television signal, double line sequential non-interlace scanning is performed by force. In this manner, the problem of sticking or ghosting of the character and graphic images is reduced.
