Abstract

PURPOSE: To obtain the special effect of the screen in a highly effective way by adding together the video signal and the inverse signal of 1-frame preceding video signal obtained at the output side of the frame memory and then delivering and memorizing the added signals in the form of the mobile video signals in case the output of the added signal is over the threshold level.
CONSTITUTION: The video signal given from input terminal 1 are supplied to output terminal 4 via connection switch 10, and the video signal and the inverse signal of the 1-frame preceding video signal obtained at the output side of frame memory 3 are supplied to adder circuit 5. Here, whether the output of circuit 5 is over the threshold level or not is detected. And in case the output is over the threshold level, the signals of memory 13 are memorized and also delivered through terminal 4 in the form of the mobile video signals. Thus, the mobile video information is preserved accurately regardless of its age to be used effectively for the special effect of the TV screen.
