Abstract

PURPOSE:To realize the reproduction of a picture in which an accurate field interlace is kept, by shifting the phase of the horizontal synchronous signal with every 2nd field in a TV picture receiver that has a double number of scanning lines. CONSTITUTION:The number of scanning lines is doubled by extracting the video signals equivalent to a frame and supplied to a TV picture receiver as the video signals equivalent to a frame. At the same time, the phase of the horizontal synchronous signal is shifted by TH/4 through a TH/4 delaying circuit 1 and with every 2nd field to perform the signal process. Thus the screen display is carried out. As a result, a picture in which the field interlace is accurately kept can be reproduced.
