ABSTRACT:
An apparatus which controls a video signal reproduced from a video compact disc to gradually fade in or out on a screen in a video disc reproducing system, is disclosed. When the video signals read out from the video disc are decoded by the MPEG video decoding section, the pulse signals are generated by the screen fade driving section responsive to both the control signal from the controlling section and the vertical synchronizing signal separated from the decoded video signal, and the restored luminance signal from the MPEG video decoding section is switched over according to the fade-in or fade-out operation by the screen fade driving section responsive to both the pulse signal and the switching control signal from the controlling section. While the decoded luminance signal is selectively provided from the screen fade driving section to the displaying equipment, the pictures fade in or out on the screen at the commencement or the end of the reproduction of the video signals. Consequently, since the pictures naturally and continuously appear and disappear on the screen, a viewer's spectral luminous efficacy is enhanced.
