Abstract: A stereoscopic feeling can be easily emphasized by properly applying seven items of: a front/rear feeling and depth feeling circuit 14 constructed by a front/rear feeling to shift a position of an image in the horizontal direction on the basis of edge information of a video signal and add to a binocular parallax and a depth feeling to set a center fusion image plane to a position behind a display surface; a glossy feeling and contrast emphasizing circuit 15 for detecting a glossy portion of the video signal and emphasizing a contrast of a single eye and both eyes in the glossy portion; a V aperture control and coring sharpness circuit 16 constructed by a vertical aperture control to raise frequencies of a middle low band or higher at a change point in the vertical direction and a coring sharpness to give a sharpness to only an edge having a large amplitude and high frequency components; and a color emphasizing circuit 17 for emphasizing color contrasts of colors other than a skin color.

Abstract: When a 2-dimensional video image is displayed, a front/rear feeling and a stereoscopic feeling are enabled to be expressed. A detection signal Sd is formed by a high pass filter 25 and a rectifying circuit 26 in accordance with an amount of edge information. The detection signal Sd is supplied to a variable delay circuit 14L. A detection signal Sd′ is supplied to a variable delay circuit 14R. The variable delay circuits 14L and 14R are controlled in accordance with the edge information amount so that a video image for the left eye and a video image for the right eye are moved in the opposite directions. Thus, an imaginary image is synthesized to the front or rear side from a display plane. The left and right video images are displayed on CRTs 20L and 20R. The projection light passes through a horizontal polarizing filter 21L and a vertical polarizing filter 21R and the left and right video images are overlapped on a screen 22.

Abstract: A vertical deflection control circuit includes a double-speed counter (18) for counting a clock with a frequency of 2f.sub.H, f.sub.H representing a horizontal frequency of an inputted video signal, in synchronism with a vertical sync signal, timing generating means (20) for judging even-field/odd-field of the input video signal and generating a timing signal based on a judged result, and offset signal adding circuitry (28) for adding an offset value to an output of the double-speed counter (18) at a timing of the timing signal, thereby a video signal in a vertical deflection system can be double-scanning-converted with a simple arrangement.
